Title: Method of controlling power up noise of bidirectional latching circuit
Inventor: HIYUNNSABU CHIYUN
IPC: G06F3/00
Filed: 1989-04-05
Abstract: PURPOSE: To minimize peak current at the time of power-up without reducing a driving capability to each direction and to restrain power up noise by having a stage which changes the trip point of each directional inverter that constitutes a bidirectional latch circuit. CONSTITUTION: The scale of a pull-up transistor 14 and a pull-down transistor M2 is different from the one of a pull-up transistor M3 and a pull-down transistor M4 , and they are not matching. Thus, the trip point of an inverter which consists of M1 and M2 is different from the one of an inverter that consists of M3 and M4 . Therefore, at the time of power-up, an inverter which has a trip point that is always reached earlier is first operated and the level of latch can always continues to be constant. Also, when the level of nodes B and C changes, their threshold on voltage and threshold off voltage are decided in such a way that they are different from each other, and the formation of a current path between M3 and M4 , or M1 and M2 . is prevented.

Title: Device for preventing conveyance of overlaid sheets in imaging apparatus
Inventor: MIZUNUMA NOBORU
IPC: B65H3/52
Filed: 1983-05-17
Abstract: PURPOSE:To prevent the conveyance of overlaid sheets of copying paper in an imaging apparatus, by using an overlaid sheet conveyance detector to control an overlaid sheet coneyance preventer to separate one sheet from the others and convey the sheets at necessary intervals. CONSTITUTION:When the front edge of one of three overlaid sheets 2 of paper is detected by a sensor 31 during the conveyance of the overlaid sheets, signals S2, S3 with levels h2, h3, respectively, are generated so that rollers 29, 10 continue to rotate, the front edge of the sheet 2 collides against the roller 29 and the sheet is slightly curved. After that, the rollers 29 still keeps rotating but the level of the signal S3 is made zero to stop the rotation of the rollers 10 to continue to convey only the uppermost sheet 2b of paper. When the rear edge of the uppermost sheet 2b has passed through the sensor 31, the sensor detects the other two overlaid sheets 2c, 2d so that the rotation of the rollers 29 is stopped a necessary time after the uppermost sheet 2b has passed through between the rollers 29.

Title: Recording and reproducing device for digital signal
Inventor: SHIMEKI TAIJI
IPC: G11B20/14
Filed: 1981-06-02
Abstract: PURPOSE:To realize high-eensity recording and reproduction which has less errors in demodulation while extracting clock information specially by an NRZ or NRZi modulation system, by inverting bits ''0'' and ''1'' at intervals of N bits. CONSTITUTION:A digital signal sequence whose frame is constituted by a frame constituting circuit 2 is supplied to a group bit inverting circuit 3, which inverts bits ''0'' and ''1'' at intervals of N-bit groups following a signal SYNC. The digital signal sequence whose frame is constituted after the group bit inversion is converted by a modulating circuit 4 into a signal necessary for recording. For NRZ modulation, modulating operation is unnucessary and for NRZi modulation, the modulating circuit 4 generates a signal for level inversion where a bit is ''1''.  A recording amplifier 5 performs amplification and the resulting signal is recorded on a recording medium.

Title: Forming method of magnetic bubble transfer path
Inventor: MATSUDERA HISAO
IPC: G11C19/08
Filed: 1984-04-27
Abstract: PURPOSE:To form a magnetic bubble transfer path having a sufficiently large difference (DELTAHk) between anisotropic magnetic fields of non-implantation area and an implantation area and an excellent temperature characteristic by implanting ions and again implanting them after annealing at a prescribed temperature. CONSTITUTION:After a mask for shielding the ion implantation is formed on a magnetic garnet monocrystal film, ions are implanted for forming a magnetic bubble transfer path. When the path is annealed at 600 deg.C or above, the lattice distortion caused by the ion implantation returns to a small value, while Curie temperature returns to an approximately original temperature. On the other hand a magnetic anisotropic constant value will not return to its original value but becomes smaller. When a small amount of ions are implanted under this condition on the outer circumference of the transfer path to the extent where the difference is produced in the inner surface direction of anisotropy, the magnetic bubble transfer path can be formed which has a slight decrease in the Curie temperature, a sufficiently large DELTAHk and excellent transfer and temperature characteristics.

Title: Fixing device
Inventor: TAKEDA KENJI
IPC: B05C1/02
Filed: 1991-04-17
Abstract: PURPOSE:To prevent the operability of transparency material and image quality from being deteriorated by changing an oil application amount to a fixing roller from an oil applying means according to the kind of the transcription material and to improve the consuming efficiency of oil by eliminating the needless oil which is taken out with a transcription material. CONSTITUTION:The hook of a spring 7 is varied to a position 71 and a position 72. Namely, when the hook is at the position 72 where the oil application amount from an oil felt 4 to the fixing roller 1 is changed, force generated by the spring 7 is larger than when it is at the position 71, so that the press-contact force of the oil felt 4 is large and an oil oozing amount from the oil felt 4 is increased. Therefore, the oil application amount to the fixing roller 1 becomes large. That is, when the hook is at the position 72, a plain paper is set as the transfer material and when it is at the position 71, the transparency is set as the transcription material.

Title: Pm analog modulation communication system
Inventor: ICHIYOSHI OSAMU
IPC: H03D3/06
Filed: 1990-03-30
Abstract: PURPOSE:To realize high S/N characteristic by forming a transmission signal with constant amplitude by synthesizing the output of two modulation multipliers at a transmission side, and outputting a signal from the phases of the output of two demodulation multipliers from a reception side to suppress a carrier. CONSTITUTION:The modulation multiplier 2a forms a signal in which a carrier signal is multiplied by a value B of constant level, and inputs it to a synthesizer 5, and obtains the output s'(t). An original sound signal is modulated with a deep modulation factor, and the modulation spectrum of the transmission signal shows the one in which the carrier is suppressed as shown in figure. At a reception side device, a reproducing carrier signal is multiplied by a reception signal r(t) by the demodulation multiplier 11. A demodulation signal d(t) is outputted from a conversion table 12 by receiving the output of the demodulation multiplier 9 and that of the multiplier 11. In other words, a ratio of low frequency component of the output of the multiplier 9 to that of the multiplier 11 is set in advance at the table 12, therefore, the signal d(t) can be immediately obtained. A signal to be modulated includes remarkable amount of distortion components due to the deep modulation factor, however, the distortion component can be eliminated at the table 12, and the original audio signal without generating the distortion can be demodulated and reproduced, which enables an S/N to be improved to the one multiplied by (A/B).
