Title: Multiwire saw
Inventor: OKUBO KAZUYA
IPC: B28D5/04
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To effectively supply slurry to a wire row by providing a guide body arranged in a comb-teeth shape so as to form the wire-traveling wire traveling groove part extending in the wire direction from the slurry supply part. SOLUTION: Slurry S is simultaneously supplied from both end parts 22 of a pipe 11 to inside of the pipe 11, and a diameter of the central part of a slurry blowoff hole 23 of the pipe 11 is formed larger than a diameter in the vicinity of both end parts 22. Thus, the slurry S is uniformly blown off from the slurry blowoff hole 23 arranged over the total length of the pipe 11 so that the slurry S is uniformly blown off in the shaft direction of a semiconductor ingot 7. The slurry S is reliably and uniformly sprayed on and applied to a wire row 4 traveling in the wire traveling groove part 14 formed between the guide plate parts 13 without scattering the slurry S in large quantities to the periphery.

Title: Digital radio communication equipment and its offset correction method
Inventor: OTSUKA MASANORI
IPC: H04L27/20
Filed: 1993-07-07
Abstract: PURPOSE:To attain automatic offset correction with high accuracy repeating the operation of correcting a differential offset in the negative direction when the offset detected by a voltage comparator is positive and in the positive direction when the offset detected by the voltage comparator is negative in the non-transmission so as to reduce the differential offset. CONSTITUTION:A differential offset is detected in the non-transmission state in the usual operation mode, generated correction data are added to input transmission data and the sum is inputted to a D/A converter 206, in which the data are converted into analog data, which are inputted to an orthogonal modulator 213. In the correction data generating mode, a sum of 1-all 0 signal and correction data is inputted as an input of the converter 206 so that a noninverting output and an inverting output are identical to each other and the output in the buffer 208 is detected by a voltage comparator 209. When the offset is positive, correction data are reduced by one step and when negative conversely, the correction data are increased by one step. The operation above is repeated till the offset reaches a detection limit of the comparator to generate correction data.

IPC: F02D41/14
Filed: 1983-09-12
Abstract: PURPOSE:To prevent deterioration of the driving performance and the specific fuel consumption of an engine, by executing learning control when an intake throttle valve and the engine load are feedback-controlled under specific conditions and the temperature of intake air is whithin a prescribed range. CONSTITUTION:A control circuit 61 executes learning of values to be learnt when an intake throttle valve and the engine load are feedback controlled under specific conditions. For this purpose, judgement is made at first that the intake throttle valve is not in its idling position and then judgement is made whether the pressure PM in an intake pipe has entered into learning region or not. In case that the judgement is YES, learning of values to be learnt is executed when the air-fuel ratio is under feedback control, the temperature THW of engine cooling water becomes higher than a prescribed value, the temperature of intake air is within a prescribed range and skipping of an air-fuel ratio feedback correction factor FAF is caused. By employing such a method, it is enabled to reduce the number of bits of memory and the number of words of a program and to prevent deterioration of the driving performance and the specific fuel consumption of an engine due to errors of learnt values.

Title: Double tub washing machine
Inventor: MATSUMOTO MASAKAZU
IPC: D06F37/42
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To efficiently transport washing water from a first washing tub to a second washing tub, by closing a connecting water passage during transporting washing water to prevent reverse flow of washing water by dehydrating motion even if the pump action is lowered by opening a lid. SOLUTION: When rinsing is completed to start a recycling process, valves 1 and 2 are opened. Washing water starts to flow from a first washing tub 20 to a second washing tub through a connection water passage by the water level difference, and washing water is transported until water levels in both tubs equals (level L1 = level L2). Then a drive device 24 starts dehydrating action and the washing water in the first washing tub 20 is smoothly transported by the pumping action to raise the water level into the second washing tub 40. If a lid 12 is opened during that period, a valve V2 is closed to close the connecting water passage and a motor 25 is simultaneously stopped. The water transportation process is performed when the drive device 24 is executing dehydration work and the transportation is continued during the former half.

IPC: H01M4/04
Filed: 1988-07-06
Abstract: PURPOSE:To obtain an alkaline storage battery with the excellent cycle characteristic by adding polysaccharide with the polymerization degree of 320 or above and its derivative to a sintered cadmium negative electrode. CONSTITUTION:Polysaccharide with the polymerization degree of 320 or above and its derivative are added to a sintered cadmium negative electrode. Since the polysaccharide with the polymerization degree of 320 or above and its derivative have a strong binding force, dropping from the negative electrode due to the charge and discharge cycle rarely occurs, and the active material utilization factor (capacity) reduction preventing effect can be maintained for a long time with the addition of a small quantity. The approach of the oxygen gas to the active material at the time of the oxygen gas absorption and reaction is not impaired, and the oxygen gas absorption performance is not adversely affected. The accumulation of inert undischarged metal cadmium is thereby suppressed, the reduction of the negative electrode capacity is suppressed, and an alkaline storage battery with the excellent cycle characteristic is obtained.

Abstract: PURPOSE:To prevent overheat of a shape memory alloy and characteristics deterioration of the shape memory alloy, by using a positive-characteristics resistor as a heater for heating the shape memory alloy, and utilizing a self- temperature control function of the positive-characteristics resistor. CONSTITUTION:A plate-like shape memory alloy 1 such as Ti-Ni alloy and a positive-characteristics resistor 2 are sandwichedly combined with each other through a silicone resin 3 as an insulating material having good heat conductivity to form an actuator.

Abstract: PURPOSE:To make the size of the thermal cathode smaller while securing the required thermal cathode area on the side of the main discharge room by providing roughness on the surface on the main discharge side of the thermal cathode. CONSTITUTION:The surface on the side of the main discharge room 4 of the thermal cathode 5 is provided with roughness. When the representative length indicating the degree of said roughness is sufficiently larger than the Debye length to be decided by the electrons, the temperature and the density in the plasma generated inside the main discharge room 4, the effective area increases due to the roughness provided on the surface of the thermal cathode 5. Thereby, the size of the thermal cathode 5 can be reduced without changing the thermal cathode area on the side of the main discharge room 4 so as to reduce all power to heat the structure holding it, the auxiliary discharge room 8 and the thermal cathode emitting radiation heat entering the auxiliary discharge room.
