Title: Electrophotographic copying device
Inventor: SATO TSUMUTOSHI
IPC: G03G21/10
Filed: 1986-12-16
Abstract: PURPOSE:To prevent a cleaning magnetic brush from being deteriorated by controlling the emission of a light emitting diode in an erasing device at its non-image part and arranging a regulating member for regulating the effective width of a carrier for the cleaning magnetic brush near the sleeve in a magnetic brush cleaning device. CONSTITUTION:On a part of a photosensitive body on which no image is formed, electrostatic charge on a non-image part, e.g. a part W forming an image within a range D is not completely erased by radiating weak light by means of said erasing device and controlled so that slight charge is left, so that small quantity of toner is stuck to the non-image part in accordance with the left charge. The toner is scraped by a cleaning carrier 74 in a magnetic cleaning device. The scraped toner Z is stuck to the surface of the carrier 74. Since the toner Z stuck to the surface acts as a circulating material, a silicone coat film 74b on the surface of the carrier 74 is not peeled off and the carrier 74 can be prevented from being deteriorated.

Title: Analogue device calibration method,analogue integrated circuit and codec
Inventor: DAGURASU JIYOOJI MAASHIYU
IPC: H03M1/00
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To decide an effective gain required to calibrate each path not trimmed by comparing an output signal generated in the path not trimmed with a signal in a trimmed path. SOLUTION: A programmable CODEC 100 of 16 channels, for example, requires highly precise trimming for only one direction of channels of T75358 channel A/D-D/A converters 104/106. Then the trimmed path is used for a reference by a DSP as a reference to calibrate other 15 channel paths included in the converters. Then the DSP 102 applies a known voltage signal to generate an output signal to the respective paths and the output signal produced from the path not trimmed is compared with the signal generated by the trimmed path. Then the effective gain is decided to calibrate the path not trimmed.

Title: Receiver for master station of time division multi-direction multiplex communication system
Inventor: ITO NORIO
IPC: H04J3/00
Filed: 1988-11-29
Abstract: PURPOSE:To surely distinguish noise from a normal signal relating to a radio channel through which a burst signal is not sent from a slave station by providing a reception electric field detection circuit to a receiver for a master station, and detecting a received electric field from the slave station. CONSTITUTION:A signal received by an RF signal reception circuit 101 in relation to a radio channel through which a slave station sends a burst signal is demodulated into a base band signal by a demodulation circuit 103, and whether or not the signal has an error is checked by a bit error rate counter circuit 105 and a CRC check circuit 106. Then a reception signal discrimination circuit 107 discriminates it to be the reception of a normal signal only when all output signals are normal in the bit error rate counter circuit 105, the CRC check circuit 106 and a received electric field detection circuit 102. On the other hand, the circuit 101 receives noise and the circuit 103 demodulates the signal with respect to a radio channel through which the slave station does not send a burst signal, since the received electric field is not detected in the circuit 102, the circuit 107 does not discriminate it as the reception of the normal signal.

Title: Planetary gearing device of automatic transmission
Inventor: KITA AKIHIKO
IPC: F16H3/44
Filed: 1990-11-05
Abstract: PURPOSE:To increase the torque capacity of a planetary gearing capable of transmitting as a while by fixing the tip of each leg to a plate member, forming a space for pinion among the legs, shortening its length, and increasing the number of pinions. CONSTITUTION:If it is assumed that the torque which one pinion 22 can transmit is equal regardless of the number of pinion 22 mounted, five pinions 22 for example transmit as a whole a torque 1.2 times as large as four pinions. When the number of pinions 22 mounted is increased without changing the outside dia. of a carrier 23, the total of the coupling lengths d2 decreases as long as the mounting, length d1 per pinion is constant, which causes drop of the coupling strength of a flange 23a with a plate member 23b. Therefore, the mounting length d1 is lessened as much as possible for example by machining which can give a higher processing accuracy than press, etc., and the coupling length d2 is increased, and thereby the coupling strength between the flange 23a and plate member 23b is secured.

Title: Magnetic recorder and recording/reproducing method
Inventor: KATO TAKAHIKO
IPC: G11B5/02
Filed: 1988-11-30
Abstract: PURPOSE:To improve recording density in magnetic recording to the extent of the recording density obtained in magneto-optical recording by irradiating a superconducting part covering a magnetic recording part with light so that a normal conductive state may be obtained and allowing a part of the line of magnetic flux to pass there. CONSTITUTION:A superconducting layer 6 is provided between a magnetic pole part 3 and a magnetic layer 2. Next, the superconducting part 8 covering a part 7 where the magnetic recording is performed is irradiated with the light beam (laser light beam) 9 so as to destroy the superconducting state only at that part and obtain the normal conductive state. In such a state, a part of the line of magnetic flux 4 passes the normal conductive part 8 and inverts the spontaneous magnetism of the magnetic layer 2 to perform the magnetic recording. At such a time, the diameter of the magnetic flux which passes the normal conductive part 8 is converged to the same size as the diameter of the laser light 9 with which the part 8 is irradiated, so that the size of the magnetic recording part 7 is made small to the extent of the diameter of the laser light beam 9. Thus, the recording density in the magnetic recording is improved to the extent of that in the magneto-optical recording.
