Title: Toner supplying method to donor peripheral surface
Inventor: NOMURA MASAAKI
IPC: G03G15/09
Filed: 1978-02-20
Abstract: PURPOSE: To achieve the improvement of toner supply efficiency to donor and the replenishment characteristic of toner by generating the vibrating magnetic fields wherein the AC components of vibration frequencies to the extent of collapsing the ears of the toner are superposed on DC components, near the peripheral surface of the donor.  
     CONSTITUTION: In the toner supply part, the first magnet 4 is disposed near the inside peripheral surface on the inner side of a donor 2 and the second magnet 5 is disposed on the outer side of the doner 2 so as to opposite to the first magnet 4 and yet an electromagnet 8 is provided in proximity to the peripheral surface of the donor on the inner side of the donor 2. The raised parts, etc. of  the fine undulation structure are magnetized by the ferromagnetism thereof. The direction of said magnetization is in the direction promoting the magnetization of the abovementioned raised parts, etc. by a pair of the magnets 4, 5 and this is accomplished by the selection of currents. Thereby, sufficient magnetic force may be acted upon the toner being supplied, hence the supply efficiency of toner to the donor 2 may be improved.

Title: Tone ringer circuit for telephone set
Inventor: NISHIMURA SHINJI
IPC: H04M1/00
Filed: 1982-02-10
Abstract: PURPOSE:To reduce a necessary amount of hardware for a digital circuit, by obtaining low alternating frequencies used as a control signal for outputting  plural frequencies to be alternated from the frequency of a call signal from a  station. CONSTITUTION:The call signal from a station of 16Hz is applied between input terminals 1 and 2, passed through a DC stopping capacitor C1, and rectified on full-wave basis through diodes D1-D4 to obtain a full-wave rectified voltage of 32Hz. Only when this rectified voltage rises above the sum of the charging voltage of a capacitor C2 and the Zener voltage VZ of a Zener element Z, a current flows to a call signal detecting circuit 11. Therefore, the ON-OFF frequency of a transistor TR becomes equal to the 32Hz frequency of the full-wave rectified waveform and from a collector current as the output of the call signal detecting circuit 11, the digital circuit 5 generates a clock of 32Hz for the generation of the control signal for outputting two frequencies alternately.

Title: Complementary type integrated circuit device
Inventor: SAEKI YUKIHIRO
IPC: H01L29/78
Filed: 1985-02-04
Abstract: PURPOSE:To inhibit a latch-up phenomenon without increasing chip size by forming an N-type semiconductor substrate, a first P-type diffusion layer, which is shaped onto the surface of the substrate and connected electrically to the outside, a second P-type diffusion layer, which is formed onto the surface of the substrate and connected at ground potential or higher, and an N-type diffusion layer, which is each shaped adjacent to the first and second P-type diffusion layers and connected at supply potential. CONSTITUTION:Structure in which an annular N<+> type diffusion layer 23 connected at supply potential and an annular P-type diffusion layer 24 connected at ground potential are each shaped onto the surface of a substrate in the periphery of a P<+> type diffusion layer 22 electrically connected to the outside is formed. When the P<+> type diffusion layer 22 is brought to potential higher than supply potential, collector currents I2 flow into ground potential through a P well 24b and a P<+> type diffusion layer 24a. Consequently, currents I2 do not participate in a latch-up. Currents I3, which are injected from the P<+> type diffusion layer 22, cross the P well 24b and flow to the inside, are brought to a value extremely smaller than conventional devices.

Title: Clock receiving circuit
Inventor: SUZUKI KATSUO
IPC: F02B75/02
Filed: 1990-01-30
Abstract: PURPOSE:To supply a clock which is free from the influence of the waveform distortion of an input clock to a high speed logic circuit by securing an exclusive OR of outputs between a frequency-dividing part which divides frequency of the input clock, and a delaying part which delays the output of the frequency- dividing part by a specific cycle. CONSTITUTION:A frequency dividing part 2 is provided to divide the frequency of an input clock together with a delaying part 3 which delays the output of the part 2 by (4n+1)/4 cycle, and an exclusive OR part 4 which secures an exclusive OR of outputs between both parts 2 and 3 and transmits this OR as an output clock. Then an OR is secured between the frequency-divided output which frequency-divided the input clock and and a delayed frequency divided output obtained by delaying the preceding dividing output by 1/4 cycle. So that a clock having the same frequency as the input clock is obtained. In such a case, a flip-flop that works only at the rise-up point of the input clock is used for the dividing operation. Therefore, the influences of the phase and amplitude distortions can be omitted. As a result, a clock which is substantially free from the influence of the waveform distortion of the input clock is supplied to a high speed logic circuit.
