Filed: 1984-06-05
Abstract: PURPOSE:To attain execution of an instruction with the fixed execution time and without discontinuing calculation even in case the divisor is equal to ''0'', by preventing an over-digit phenomenon of a multiplier in case the divisor equal to ''0'' in an arithmetic of a pipeline system. CONSTITUTION:A divisor D is set to a register 2 and a reciprocal table 12 is retrieved to obtain an approximate reciprocal T. The divisor D is supplied to a dividend register 1 from the register 2, and the reciprocal T is set to a multiplication register 3. The divisor D is multiplied by the reciprocal T and a product D.T is obtained at a register 6. Then a dividend N is supplied to the register 1 and multiplied by the reciprocal T. When the residue R1 equal to N.T is obtained at the register 6, the code, integer part and a bit down to a decimal point are supplied to a partial quotient calculation correcting circuit 11. The corrected partial quotient Qi obtained from the circuit 11 is sent to a register 7 and fed to the lowest digit of the register 7. Then the preceding contents are shifted to the left by a digit.

Title: Optical writing device
Inventor: YAGI MICHIO
IPC: G03G15/04
Filed: 1990-04-27
Abstract: PURPOSE:To prevent color slurring and the lowering of resolution without strictly regulating the positional deviation of a photosensitive body in a main scanning direction in the case of performing multiple writing by providing a mechanism which detects the positional deviation of the photosensitive body and corrects an optical writing position corresponding to the detected result. CONSTITUTION:The position of the photosensitive body is detected by a photosensitive body position detecting means 5 by judging a boundary between a cell which receives and detects light from an LED 14 by a photosensitive body position detecting sensor 15 in an array state and a cell which does not receive and detect the light. A write timing decision means 7 receives a signal PS from the means 5 and an index signal ID from an index sensor 6 and adjusts write start timing so as to correct the writing position corresponding to the positional deviation of the photosensitive belt 4. It is desirable to perform the correction every time one line of write is performed, but the correction is performed once or plural times for the write of one image or the correction is performed once for the write of plural images.

IPC: F02D41/02
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To restrict the increase of NOx exhausted quantity so as to always maintain the excellent exhaust gas characteristic by setting a degree of richness of air-fuel mixture larger, as much as the exhaust gas flow or exhaust gas flow speed is increased, in a reducing means for increasing richness of the air-fuel mixture so as to reduce NOx , which is absorbed by the NOx absorbent. SOLUTION: When an engine 1 is operated in the condition that the feedback control is carried on in response to a detection value of a LAF sensor 14, an ECU 5 judges operating condition whether the lean burn control is necessary or not. In the case where a judgment is YES, an increased variable of a counter is computed in the condition that a target equivalent ratio is equal to the predetermined equivalent ratio, which is set a little nearly close to a lean side, or less. Continuously, a value of the counter is incremented by the increased value, and in the case where a value of the counter is equal to the predetermined threshold value, a down count timer is set at the predetermined time for low rotation in a low rotation area. Thereafter, the timer is started, and the reduction richness target equivalent ratio is computed, and a constant of the final target air-fuel ratio is set at a value of the reduction richness target equivalent ratio.

Title: Ion generating device
Inventor: UCHIDA TSUTOMU
IPC: F24F1/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent contamination of a product and a peripheral wall due to electrostatic charge through a comparatively simple circuit by intermittently applying a pulse wave on a radiation electrode by a high voltage generating circuit. SOLUTION: An ion generating device regulates an ion generating amount by a relay 27, arranged between a high pressure generating circuit 26 and a power source, in a way that a radiation electrode 17 composed of a pointed aluminum sheet and a needle is connected to a high voltage generating circuit 26, which boosts an AC 100 volt 50 Hz or 60 Hz commercial power source to a potential of a DC approximate -8 kV by a pulse wave having a 4 μSec width, such that the potential of the radiation electrode 17 reaches approximate -8 kV, and an ion generating amount is regulated by a relay 27 arranged between the high voltage generating circuit 26 and a power source. When an ion generation switch is turned on, a relay 27 is turned on, and the ion generating device repeats intermittent operation of ten-minute operation and one-minute stop.  This constitution reduces adhesion of electrostatic charged dust and smoke to a product and a peripheral wall since negative ion drifting at the periphery of an air-conditioner and a casing surface is damped. Further, in this case, ozone harmful to a human body is hardly generated.

Abstract: PURPOSE:To increase a breakdown strength in a well region and to improve a load-resistant amount by a method wherein, after the well region is formed, a high-concentration region is formed selectively at the bottom of the well region by a high-energy ion implantation method. CONSTITUTION:An N<-> type epitaxial layer 2 is grown on the surface of an N<+> type semiconductor substrate 1; after that, an oxide film 3 is formed on its surface; a window 3a is opened in the film 3. Then, a P-type well region 4 is formed by making use of it as a mask; after that, a resist 5 is formed; the resist at the part of the window 3a is removed; high-energy ions are implanted through the window 3a; an N<+> region 6 is formed at the bottom of the region 4, i.e., at the boundary part to the layer 2. Since the high- concentration N<+> region exists at a P-N junction part of the region 4 to the layer 2, a breakdown strength at the region 4 is enhanced, and electric current hardly flows to an N<->-P-N<+> parasitic transistor constituted of the layer 2, the region 4 and an N<+> type source region 10, and a load-resistant amount is enhanced. Thereby, a breakdown strength is increased at a well region and the load-resistant a mount can be improved.

Title: Hot water supply combined with space heating system utilizing solar heat
Inventor: OOTSUKA NOBUO
IPC: F24S90/00
Filed: 1982-07-01
Abstract: PURPOSE:To increase the availability of a heat storage tank and the rate of dependability of the system on solar heat by a method wherein the titled hot water supply system is formed to have a simple structure such that heat collecting heat exchangers are arranged at the intermediate part and the lower part, respectively, of a heat storage tank, a space heating heat exchanger is arranged at the upper part of the heat storage tank and hot water supply ports are formed in the intermediate part and the upper part, respectively. CONSTITUTION:When the amount of insolation increases, an operating liquid in a heat collecting circuit pipe 3 flows into a second heat exchanger 2B through a first heat exchanger 2A from a solar heat collector 4 due to the action of a hot water circulating pump 5 operated according to a command signal from a differential thermostat. The operating liquid heated by the solar heat collector 4 exchanges heat with water in the heat storage tank 1 at the first heat exchanger 2A to thereby heat the water while the temperature of the liquid itself drops. Then the operating liquid enters the second heat exchanger 2B to heat the water between the second heat exchanger 2B and the first heat exchanger 2A in the heat storage tank 1 so that the temperature of the operating liquid drops further and the liquid returns to the solar heat collector 4 again. Further, except in the space heating season, it is preferable to operate the system by opening the upper hot water feed valve 18 and closing the intermediate hot water feed valve 20.
