摘要:
Water content sensing and informing system for a disposable diaper consisting of water permeable inner sheet, water absorber, and water impermeable outer sheet, comprises at least one pair of metal layers, one surface of one layer being covered with an electric insulating layer, formed between the water impermeable outer sheet and the water absorber, a detector for detecting water content absorbed in the diaper, and an informing mechanism for informing the detected result. The pair of metal layers is isolated with constant distance to each other and extended in the longitudinal direction of the diaper. The pair of metal layers is formed in a thin layer by a lamination or vacuum evaporation of a metal leaf. The informing mechanism is selected from a visual, auditory, remote informing device using an oscillator and receiver, or combination of these.

A gain control circuit comprising a pair of transistors constituting a differential amplifier, and a pair of resistors each connected to the emitter of one of the transistors and having a sufficiently great resistance value compared with 1/gm of the transistor in the transistor operating range, the resistors being connected to a common regulated current supply to supply the halves of control current from the regulated current supply to the respective transistors, a pair of diodes are connected to the collectors of the respective transistors as a load, and a first variable resistor means is disposed in the current path traced from the diodes to the regulated current supply via the transistors and resistors for compensating fluctuation of the diffused resistance of the diodes. Further, a second variable resistor means is disposed in the base bias circuit for the transistors for compensating fluctuation of the base-emitter voltage of the transistors.

An image forming apparatus includes: a deciding unit that decides whether in-monitoring assertion information representing is recorded in the information storing unit by another image forming apparatus or not; a recording unit that generates new in-monitoring assertion information; an acquiring unit that acquires information to be an image forming target; and an executing unit that executes an image formation processing. The recording unit decides that the condition of the expiration is satisfied when an expiration date represented by information indicative of the expiration date elapses if the information is included in the in-monitoring assertion information recorded by the another image forming apparatus, and the recording unit does not generate the in-monitoring assertion information and the executing unit does not execute the image formation processing in that case when the predetermined condition of the expiration is not satisfied.

A stacked-type, multi-flow heat exchanger includes a first header pipe and a second header pipe formed opposite the first header pipe. The heat exchanger also includes a plurality of heat transfer tubes extending between the first header pipe and the second header pipe, such that the first header pipe and the second header pipe are in fluid communication via the heat transfer tubes. The heat exchanger further includes a plurality of fins alternately stacked with the plurality of heat transfer tubes. Moreover each of the ends of the first header pipe includes a first tapered portion having a reduced diameter relative to a diameter of a center portion of the first header pipe. In another embodiment, each of the ends of the second header pipe includes a second tapered portion having a reduced diameter relative to a diameter of a center portion of the second header pipe.

At least one flow control member (127a) is fitted in a fitting groove (133) formed in a tank (121). An insertion hole (204) is formed in at least a part of the fitting groove (133). The flow control member (127a) has a projection (205) to be inserted into the insertion hole (204). The projection (205) is smaller in size than the insertion hole (204). The flow control member (127a) is arranged at a predetermined position within the tank (121). The fitting groove (133) is defined by a pair of side wall portions (203b) formed by internally cutting a tank wall of the tank (121) in a thickness direction along a pair of parallel cutting lines, and a guide portion (203a) formed by extruding a portion of the tank wall between the side wall portions (203b). The insertion hole (204) penetrates the guide portion (203a). The projection (205) has first and second tapered portions (351, 352, 354, 355) so that the thickness and the width are reduced towards the top end.

A magnetic recording and reproducing apparatus including a recording head, reproducing heads and reproducing pre-amplifiers each mounted on a rotating cylinder for allowing recording and reproducing operations at the same time, in which two signal channels are defined by first and second double azimuth heads each made up of two reproducing heads and first and second integrated circuits are arranged on the rotating cylinder in close proximity to the first and second double azimuth heads, respectively. Each of the integrated circuits includes two pre-amplifiers corresponding to two reproducing heads of the first or second double azimuth head and selectively outputs one of two amplified reproduced signals from the above pre-amplifiers which is higher in signal level, and a head discrimination signal is added to the output signal. The input part of each reproducing pre-amplifier is constructed to perform a differential operation, and one of the output signals of the first and second integrated circuits is selectively sent to a fixed side through a single transmission means in accordance with a control signal supplied from the outside. The magnetic recording and reproducing apparatus having the above construction can be made small in jitter and crosstalk, and can reduce the number of elements for transmitting signals between the rotating cylinder and the fixed side.

A discharge lamp comprises a cylindrical lamp casing substantially formed of a metallic material, a transparent glass plate air-tightly fitted to one of the opened end of the lamp casing, a sealing stem air-tightly closing the other opened end of the lamp casing, and a pair of cathode and anode elements sealed in the lamp casing together with discharge gas. The lower portion of the lamp casing may be made in square or circular structure and may be composed of a metallic cylindrical portion extending to a half way of an axial length of the cylindrical lamp casing and a cylindrical transparent glass portion tightly surrounding the outer periphery of the metallic cylindrical portion of the further extending portion and having a front end extending to the sealing stem closing the other end of the lamp casing. The discharge lamp further comprises a member for regulating discharge generated between the paired cathode and anode elements and the interior of the discharge regulating member is divided into a plurality of luminous chambers so that the discharge lamp operates as a fluorescent lamp. The improved structure of the discharge regulating member can improve the light distribution characteristic of the fluorescent lamp.
摘要:
A variable capacity vane compressor has an annular control element angularly displaceably received within an annular recess formed in one of side blocks defining a cylinder. The control element is angularly displaced in response to a difference in pressure between first and second pressure chambers formed in the one side block and communicating with a zone under lower pressure and a zone under higher pressure, respectively, and to the biasing force of a biasing member, thereby varying the opening angle of at least one second inlet port formed in the one side block and hence controlling the capacity of the compressor. A positioning device is provided at a radially inner portion of the control element to radially position the control element in place within the annular recess of the one side block with reference to the radially inner portion of the control element, thus relieving the hysteresis between angular displacement of the control element in one circumferential directions and that in the opposite direction. At least one oil groove is formed in the inner peripheral surface of the control element to guide lubricating oil for lubricating the same element and its associated sliding parts to a sufficient degree to further reduce the hysteresis.
