Title: Multiplier
Inventor: KURODA YASUHIRO
IPC: G06F7/527
Filed: 1982-06-30
Abstract: PURPOSE:To realize pipeline constitution without causing a decrease in arithmetic speed, by sectioning a multiplier into plural bits and multiplying a multiplicand by a corresponding decoded value, and inverting the sign bits of partial products and then summing up the resulting partial products in a digit-shifted state. CONSTITUTION:The multiplier is sectioned into plural bits and the multiplicand is multiplied by the corresponding decoded value; and the sign bits of partial products corresponding to respective sectioned bit groups and the resulting partial products are shifted in digit and summed up together with a correcting value with a predetermined pattern. For example, partial products A, B, and C corresponding to sectioned bit groups are set in registers 5-0, 5-1, and 5-2 and the sign bits A0, B0, and B0 of the partial products are inverted. The resulting partial products (-A0A1A2-A6), (-B0B1B2-B6), and (-C0C1C2-C6) are shifted in digit and summed up by a partial product adding circuit 6 together with the correcting value with the specific pattern, and the sum result is sent out to an output register 7.

Title: Communication control equipment
Inventor: MARUYAMA MASATO
IPC: H04L69/14
Filed: 1983-06-22
Abstract: PURPOSE:To reduce the quantity of hardware of a communication control equipment by providing a memory which holds numerous combinations of answer information commonly to plural circuits. CONSTITUTION:When a transmission controlling section 220 receives a next transmitting character request signal from a character buffer section 231i of the i-th circuit, the section 220 reads out a circuit state word for the i-th circuit in a circuit state word holding section 221. When an answer information effective bit is ''1'', the controlling section 220 does not make any DMA transmitting process and reads out one character from an answer information holding memory 224 by means of an answer information memory address contained in the circuit state word, and then, decrements the lowest two bits of the answer information memory address after setting the one character in the character buffer section 231i.

IPC: H02M7/12
Filed: 1994-04-28
Abstract: PURPOSE:To discharge the energy stored in reactors to a load through inverse- parallel circuits by alternately controlling the turn-on/off of two switching elements connected to each other in series at a frequency higher than that of AC power supply. CONSTITUTION:A sine wave rectifier circuit is provided with capacitors 2a, 2b, and 2c and serial circuits of a diode 3a and reactor 4a, diode 3c and reactor 4b, and diode 3e and reactor 4c corresponding to each phase of AC power supply 1.

Title: Control system for scratch memory
Inventor: ASAMI RIYOUICHI
IPC: G06F12/00
Filed: 1977-09-21
Abstract: PURPOSE:To increase the speed of the data processor by giving a parallel action to the read and write of the scratch memory and the operation wihtout changing the basic itime (clock). CONSTITUTION:Scratch memory 2 performs both reading and writing actions within one clock. In other words, the selected 5 reading address is set to address register 1 at the reading action time to carry out the reading of memory 2, and the data is read out to be set to data register 6. Then the writing action is given, and address selector circuit 5 selects the read-in address through control of read/write control circuit 8 to set it to register 1. Through this address, the contents of writing data register 7 are written into memory 2. After this, the calculated result (operation-1) of arithmetic circuit 3 is written into memory 2 (solid line). At the same time, the data of memory 2 read out at preceding R-1 is trasferred to circuit 3 to perform operation-2 (dotted line). Thus, the read/write action of memory 2 is carried out in parallel to the action of circuit 3.

Abstract: PURPOSE:To reduce sliding load between the projection of a main body on replenishing part and the seal of a cartridge by providing a rotating member the head of the projection for opening the main body replenishing part in a 2nd area. CONSTITUTION:The openings 7, 11 of the cartridge 1 are inserted into the inlet 20 of the toner replenishing part 2. When the projection 21 is abutted upon the seal 8 covering the opening 11 in the 2nd area 10 and pressed into the opening 11 through the rotating member 22, the part 14 of the seal 8 is taken off from the opening 7 and toner 6 is supplied to the developing device side replenishing part 2 through the openings 7, 23. When the cartridge 1 is lifted up after supplying the whole quantity of toner, the cartridge 1 is taken out in the state that the seal 8 is fixed on the cartridge 1 on both end sides and stored in the area 10. Since the seal 8 is folded through the member 22, frictional force due to sliding is not almost generated and the sliding load between the projection 21 of the body supplying part and the seal 8 of the cartridge 1 can be reduced.
