Title: Dividing circuit
Inventor: KAWAMOTO YASUHIKO
IPC: G06F7/52
Filed: 1989-08-28
Abstract: PURPOSE:To execute the dividing operation at high speed without increasing hardware by providing two multiplexers and a detecting circuit for detecting whether or not the high-order bit data of a divisor is zero, and controlling the data selecting action of a multiplexer with a detecting signal from the detecting circuit. CONSTITUTION:Since the high-order bit data of a remainder becomes zero when the high-order bit data of a divisor is zero, only the subtraction of the low-order bit data of the divisor and the contents of a remainder register is executed. On the other hand, since the high-order bit data of a quotient becomes zero when the high-order bit data of the divisor is not zero, the subtraction of the low-order bit data of the divisor and the high-order bit data of a dividend and the subtraction of the high-order bit data of the divisor and the contents of the remainder register are executed. Thus, when the divisor and the dividend are set to N bits, in both cases, the prescribed quotient and dividend can be obtained by the subtraction operation of N times by using the subtracter of an N/2 bit length processing.

Title: Core clamping device of stationary induction machine
Inventor: WATANABE TORU
IPC: H01F27/26
Filed: 1984-10-24
Abstract: PURPOSE:To reduce the weight of inverted U-shaped coupling fittings engaged with core clamping fittings by obliquely forming at the corner the coupling fittings along the shape of a core, thereby reducing the bending moment of the welded portion of the coupling fittings. CONSTITUTION:Coupling fittings 3 are inclined at both ends to reduce L1, and when the strength of the fittings 3 is considered to be equivalently both end supports and equally distributed load, a bending moment M acted at the corner decreases, and the thickness T1 reduces. The oblique sizes A1, B1 of an upper tank 10 in the drawing can be increased as compared with the oblique size of the corresponding conventional upper tank. From this, the thickness of the fittings 3 can be reduced as compared with the conventional on to reduce the weight. Further, the oblique size of the tank 10 is increased to reduce the inner volume of the upper tank, and oil amount can be decreased. Moreover, the height of the upper tank 19 can be reduced in the amount of the thickness reduction of the fittings 3 by equalizing gaps between the fittings 3 and the tank 10.

Title: Image forming device
Inventor: TSURU TETSUHIRO
IPC: G03G15/08
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of obtaining an image of high quality by preventing the chemical change and filming of a photoreceptor caused by ozone and NOx . SOLUTION: The difference in circumferential speed between the photoreceptor 1 and a developing roller 5, in nondevelopment is made larger than that in development and the circumferential speed of the developing roller 5 in the nondevelopment is lower than that in the development. When voltages applied to the developing roller 5 and a toner supplying roller 6, in the nondevelopment are defined as VB and VSR respectively, the relation of |VSR|<|VB| is satisfied, where the VB has the same polarity as that of the charge of toner 10 or the opposite polarity relation of the VSR to the polarity of the charge of the toner 10 is satisfied.  Or the relation of |VSR|>|VB| is satisfied, where the VB has the polarity opposite to that of the charge of the toner 10 or the VSR has the polarity opposite to that of the charge of the toner 10, where VB=0. Thus, the shortening of the life of a developing unit is prevented so that the chemical change and filming of the photoreceptor 1 caused by ozone and NOx can be prevented as well.

Abstract: PURPOSE:To continuously record and reproduce sound data beyond the capacity of a memory by reading or writing the sound data after the sound data to be read or written is temporarily transferred to an auxiliary memory if writing the sound data to a main memory overlaps with reading it to the main memory. CONSTITUTION:When sound signals that an input terminal 7 can obtain continuously for 20 sec are recorded, sound signals in the next ten sec are supplied to an input terminal 10c in the middle of reading and recording data out of a memory 10. Hence the sound signals that the input terminal 10c obtains are stored in the auxiliary 10b about every 89 musec. Right after signals are completely read out of the main memory 10a, the sound signal stored in the auxiliary memory 10b are read in a short time, and written in the main memory 10a as it is. Thus the sound signals for 20 sec are continuously recorded on a disk D.
