Title: Wavelength tunable laser device
Inventor: KAWAHARA HIDETO
IPC: H01S3/106
Filed: 1989-09-04
Abstract: PURPOSE:To accurately detect the center wavelength of laser rays for a long term by a method wherein the intensity of a part of the laser rays is compared with that of another part of the laser rays which penetrate through an absorbent. CONSTITUTION:Laser rays, which are set narrow in bandwidth and to a prescribed wavelength, are separated into a first laser ray 181 and a second laser ray 182 through beam splitter 131 and 132, and the laser rays 181 and 182 are directed to an absorption cell 14 and a laser ray intensity detector 152 respectively. The absorption cell 14 is charged with vapor possessed of an absorption line of frequency nearly equal to the set frequency. The first laser ray 181 which penetrates through the absorption cell 14 is directed to a laser ray intensity detector 151. The laser rays measured by the laser ray intensity detectors 151 and 152 are compared with each other in intensity, whereby the center wavelength of the laser rays are detected. By this setup, the center wavelength of laser rays can be accurately detected for a long term independent of influences such as the fluctuation of the output of a laser in continuous operation.

Title: Electrophotographic device using photoconductive toner
Inventor: YAMAOKI TOSHIHIKO
IPC: G03G15/05
Filed: 1989-09-04
Abstract: PURPOSE:To improve transfer efficiency without dropping development characteristics by exposing photoconductive toner for being served as the conductive toner during development and electrification and eliminating the need of giving light to the photoconductive toner for being served as high-resistance toner during transfer. CONSTITUTION:When infrared rays expose the photoconductive toner 21 during the electrification and the development, the resistance of the toner 21 drops and acts as the conductive toner. A strong electric field is given between the surface of a brush 2 and an electrostatic latent image carrier 1, and triboelectrification is carried out in that condition. When an optical image projected from a recording head 3 is made incident ton the optical conductive layer 14 from the inside of the transparent supporting body 11, the potential of the exposed part drops and the toner adheres to the surface of the carrier 1 from the magnetic blush 2. Since the transferred part is in a position where light from an infrared rays source 22 is covered, the photoconductive toner acts as insulating toner. Therefore, an actual toner image on the surface of the carrier 1 is efficiently transferred to a recording sheet 5 by a transfer roller 4.

Title: Controlling method and device of electric railcar chopper
Inventor: UENISHI AKIRA
IPC: H02P7/03
Filed: 1983-12-06
Abstract: PURPOSE:To prevent a semiconductor switch from damaging by setting both an armature current and a field current to zero when an operation command is released and then opening a breaker. CONSTITUTION:When an operation command is released, switches SW1a, SW1b are opened, and SW1b, SW2, SW3 are changed. Thus, a conduction rate command gammaa of an armature chopper is outputted in response to a value produced by subtracting a current pattern Ip gradually decreasing from an armature current Ia when an operation command outputted from a memory 1 is released by the armature current Ia. On the other hand, a conduction rate command gammaf of a field chopper is outputted in response to a value produced by subtracting a value mutliplied by the conduction rate (If/Ia) and the current Ia when the operation command is released by a field current If. When the currents Ia and If become zero, a breaker is opened.

Title: Game object lending system
Inventor: KISHIDA ICHIRO
IPC: A63F7/02
Filed: 1987-09-16
Abstract: PURPOSE:To judge what causes abnormalities in the reception of data by receiving a responsive signal delayed according to its own address in the reception of predetermined data to judge whether or not its own lending machine is abnormal on the basis of the abnormal condition detected by an abnormally detecting means. CONSTITUTION:To one set of a controller are connected a plurality of card system ball lending machines. Addressing switches 130 are differently addressed to discriminate these lending machines. The transmission and reception section 113 of said machine in the reception of security data generates the responsive signal delayed by a time corresponding to its own address. Thus, if the addresses of said machine are set overlapping each other erroneously, the responsive signals are simultaneously sent from said machines to a transmission line TL. Then, signals on the transmission line TL are disturbed to be judged as abnormal responsive reception. Thus, only said machine indicated to have errors is examined so that the addressing overlaps can be found.

Title: Diagnosing system for logical circuit
Inventor: HIYAMA TORU
IPC: G01R31/28
Filed: 1984-11-02
Abstract: PURPOSE:To facilitate the diagnosis with a light detection rate, by performing the diagnosis with the scanning in and out of a switch insertion circuit section after a logical circuit is traced in the fan-in direction to determine the insertion position of a switch from the number of gates. CONSTITUTION:The partial circuit of a large logical circuit is divided into subdivision circuits 1-4. The subdivision circuit 1 is allowed to set data through a switch circuit from alpha, beta and gamma to make the data observable through the switch circuit from FF(a). Likewise, subdivision circuits 2-4 can be diagnosed individually as small circuit using FF (l), (m), (n) and (o) as scan input points and alpha, beta and gamma as scan output points. Upto the present, giant circuits is hard to diagnose because it cannot be handled by the ordinary divided circuit or unavoidably requires huge processing time. But according to this invention, it can be divided into split circuits easy to handle and scanning in or out can be done freely from division points such as alpha, beta and gamma thereby assuring a high diagnosis detection rate and processing speed.
