摘要:
A cooking heating apparatus is provided in which an object to be heated is subject to char cooking, the apparatus having a detector circuit for detecting the charred condition by detecting the intensity of reflected visible light from the surface of the object and a heating device for burning and removing foreign materials created upon heating the object and deposited on a transparent glass which is provided for preventing the foreign materials from reaching a light source which provides the visible light and a photosensor which detects the reflected visible light. The apparatus may further comprise means for forcing off the foreign materials burnt by the burning and removing elements by means of a forced air flow and/or a device for scattering the foreign materials given off from the object upon heating to prevent the foreign materials from reaching the transparent glass.

Disclosed is an improved burn-in and test method of semiconductor wafers each having numerous integrated circuits formed therein. It includes the steps of dividing each semiconductor wafer into blocks each including some integrated circuits; giving each block an address to indicate in which part of the semiconductor wafer the integrated circuits of the block are placed; recording the addresses of all blocks; preparing burn-in boards each having sockets to detachably hold carriers each bearing an identification code; loading each carrier with a block to be tested; fitting each carrier in a selected socket in the burn-in board; and carrying out the burn-in and required tests on the blocks of each burn-in board. Analysis of test results permits the locating of defective integrated circuits, if any in semiconductor wafers in terms of the recorded addresses of the blocks and the identification codes of the carriers.

A stripline patch antenna having a slot plate which is capable of obtaining higher antenna gain, while reducing the loss due to the feed lines. The antenna includes at least one radiating element for transmitting and receiving radio waves; a feed line for transmitting signals to and from the radiating element; a dielectric substrate for supporting the radiating element means and the feed line means; a grounding conductor located below the dielectric substrate; and a slot plate located above the dielectric substrate, having a plurality of slots more numerous than the radiating element. The triplate substrate can be adapted to this antenna. A plurality of antenna units so constructed can be arranged in array such that at least one of the slots of each antenna unit is shared with a neighboring antenna unit.

Disclosed is a microwave heating apparatus which comprises a turntable for reducing the irregularity of heat with the rotation movement of a subject to be heated within a heat chamber, a bread casing used for automatically performing an entire process of kneading raw ingredients, fermentation, gas escape, baking and the like, a first driving shaft made of a metal pipe and provided to drive a kneading blade mounted within the bread casing, and a second driving shaft made of a microwave-permeable dielectric substance provided to drive the turntable, the second shaft being arranged to pierce a hollow portion of the first driving shaft. According to the aforementioned construction, the turntable and the kneading blade can be effectively driven by the respective optimum motors. A choke cavity and a disk shaped conductive plate prevent microwave energy from leaking out of the heat chamber along the respective driving shafts.

A heat sensitive record material comprising a support sheet and a record layer formed on the support sheet, the record layer being composed essentially of a colorless or light-colored fluoran compound, an acidic substance which is thermally reactive with the fluoran compound to develop a color and a binder, characterized in that said record layer contains an effective amount of at least one benzenesulfonamide compound represented by the general formula: ##STR1## where R.sub.1 is a hydrogen atom, a C.sub.1 -C.sub.5 alkyl group, an acetylamino group or a halogen atom, R.sub.2 is a hydrogen atom, a C.sub.1 -C.sub.5 alkyl group, a cyclohexyl group or a phenyl group which may be substituted and R.sub.3 is a C.sub.1 -C.sub.5 alkyl group, a cyclohexyl group or a phenyl group which may be substituted, provided R.sub.2 and R.sub.3 may form together with N a saturated ring.
摘要:
A method of producing resin powder in which a resin solution prepared by dissolving a resin in a water-miscible solvent is sprayed from a nozzle while spraying water from another nozzle located close to the first-said nozzle so as to form fine emulsified droplets of said resin solution in water, then at least a substantial portion of the water-miscible solvent in said emulsified droplets is rapidly transferred into water to produce a suspension of resin powder. The suspension is then filtered. Apparatus for practicing this method is also provided.

A solid-liquid separation device includes a plurality of fixed members and movable members that are movably disposed between the adjacent fixed members, and a screw extending through the fixed members and the movable members in a state where the screw is not in contact with the fixed members and the movable members. The screw is rotationally driven about a center axis line thereof. A filtrate separated from an object is discharged to the outside of the solid-liquid separation portion through filtrate discharge gaps, and the object that has a reduced liquid content ratio is discharged from the outlet to the outside. In order to increase significantly a dewatering ratio, the movable members are formed to move while penetrating closer to the center axis line of the screw than an outer circumferential edge of the blade of the screw, without coming into contact with the screw.

The pattern line width of a coil is partially widened in a predetermined dimension and wiring patterns of a coil on the surface side and a coil on the rear side are arranged so as not to be in overlapped positions. Consequently, a direct current resistance of the coil can be reduced and an adverse influence by a self resonance of the coil on a communication can be reduced.
