Abstract:
The object of this invention is to produce a monitor which can correctly distinguish normal from abnormal vibration using automatically selected monitoring features and algorithms. The monitor can be used with a variety of devices with different vibration characteristics. The monitor according to this invention has a sensor that detects the vibration of an object. The monitor is operated in learning mode when the object is vibrating normally. The waveform of the vibration detected by this sensor is sampled over an appropriate period and analyzed. The data for each sampling feature are subjected to statistical processing, and the data which evince slight change are extracted as monitoring features. A monitoring algorithm is automatically made for these monitoring features. The algorithm selected in learning mode are used to evaluate the vibration of an object when the monitor is in operating mode. The operator does not need to set up the algorithm, and can monitor the object with a more reliable algorithm than the conventional one selected by fixed monitoring features.
Abstract:
An image display device capable of uniforming luminance over a whole display plane. The image display device includes a plurality of vertical selecting electrodes each adapted to adjust an intensity of each of electron beams for every one of a plurality of cathodes. The device may include a protective electrode for insulating a low voltage region for selecting and deflecting of each electron beam and a high voltage region for accelerating the electron beam from each other.
Abstract:
A camera is arranged such that when a film housed in a film cartridge is loaded into a film cartridge chamber of the camera with a leader portion of the film remaining outside the camera and upon closure of the film cartridge chamber, the leader portion of the film is retracted into the camera and the film is wound onto a film winding spool. This camera comprises a retracted-amount measuring system for measuring the retracted-amount of film when the leader portion thereof is retracted into the camera and a wound-amount detector responsive to an output of the retracted-amount measuring system to determine the amount of the film wound onto the film winding spool.
Abstract:
A reproduced signal switching circuit for a reproducing apparatus, comprises a switching circuit for switching output signals of rotary heads for special reproduction so as to obtain a continuous reproduced signal, a switching signal producing circuit for producing a switching signal responsive to an output pickup pulse of a rotation detecting circuit which detects the rotation of a rotary body which is mounted with the rotary heads, and for applying the switching signal to the switching circuit so as to switch the switching circuit, and a voltage supplying circuit for supplying a voltage which is in accordance with a tape moving speed to the switching signal producing circuit during the special reproduction. The switching signal producing circuit comprises time constant circuits for starting charging operations responsive to the pickup pulse, and a circuit for producing a switching signal having a polarity which changes when charged voltages in the time constant circuits reach a predetermined voltage. The voltage supplying circuit supplies the voltage to be charged to the time constant circuits.
Abstract:
In the disclosed circuit, an electromagnetically driven shutter is opened and closed by an electromagnetic drive device. A detector senses the current through or the voltage across an exciting member of the electromagnetic drive. A drive circuit is controlled by a comparator which compares the output of a constant voltage source with the output of the detector. The drive circuit is regulated so that when the shutter is opened and closed, the current is maintained at predetermined values so as to always keep the shutter characteristics constant.
Abstract:
In the drive system disclosed, a first power source supplies a driving current to drive a moving member of an electromagnetic shutter driving device in one direction or in the reverse direction a second power source device consisting of a DC booster circuit, a capacitor, etc.; a photo-to-electric converter circuit discerns the brightness level of an object to be photographed and controls the outputs of the first and second power source devices to shift between these two outputs. An automatic change-over supplies the output of the second power source to the electromagnetic shutter driving device when the level of the output of the photo-to-electric converter circuit is equal to or above a predetermined level and supplies the output of the first power source to the electromagnetic shutter driving device when the output level of the photo-to-electric converter circuit is lower than the predetermined level.

Abstract:
Since no access history is generated for when a file update which makes use of a copy and paste function is performed, it is difficult to detect the file that served as the reference source during the update. Hence, the present invention is provided to manage a client access history for each file that is stored in a storage device, and detect a file, which has been accessed between a time when a corresponding user logs into the storage device and a time when an updated file is updated based on information of the access history, as the reference source for the updated file.
Abstract:
The present invention relates to a Cu—Sn—O alloy plating having an oxygen content of 0.3 to 50 at %, a copper content of 20 to 80 at %, and a tin content of 10 to 70 at % in the plating. The present invention provides a copper tin alloy plating that has excellent plating adhesion and disengaging force stability and particularly a Cu—Sn—O alloy plating that has a blackish color tone without containing any controlled substances.
