Title: Charge/discharge control circuit
Inventor: SUGIURA KAZUNARI
IPC: H02J7/00
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To stop discharge before a switching circuit generates heat and breaks down, by performing discharge control receiving the signals of a circuit which detects two kinds or more of different voltages of overcurrent detecting terminals, and exhibiting a discharge stopping function by an appropriate delay time, against two kinds or more of different load currents. SOLUTION: The reference voltage 111 of a reference voltage circuit 105 is set higher than the reference voltage 112 of a reference voltage circuit 106, and the delay time of a delay circuit 109 is set shorter than that of a delay circuit 110. By performing setting this way, a switching circuit 103 is turned off after the delay time preset by the delay circuit 110, when an overcurrent flows and the voltage of a current sensing resistor 104 is kept higher than the reference voltage 112 and lower than the reference voltage 111. Accordingly, it becomes possible to turn the switching circuit off by a shorter delay time than the switching circuit generates heat and breaks down, even if something abnormal happens and an excessive current flows.

Filed: 1996-01-15
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which is constituted to secure a sufficiently large design margin in the device, to make the occupying area of the device on a chip smaller, and to suppress the occurrence of faults caused by the electrical continuity of a remaining film and a fuse cutting method.

Title: Polishing fluid
Inventor: GENJIDA FUMIHIDE
IPC: B24B37/00
Filed: 1985-02-06
Abstract: PURPOSE:To provide good dispersion stability in machining fluid and prevent it from easily precipitating an abrasive grain by ageing, by containing polyvinylpyrrolidone, water and diamond abrasive grains. CONSTITUTION:Polyvinylpyrrolidone is used with molecular weight at least 10,000 particularly 20,000-80,000 preferable. The polyvinylpyrrolidone with molecular weight less than 10,000 provides a small effect stably dispersing a diamond abrasive grain in the water. While the diamond abrasive grain is used with its average grain size normally in 20mu or less preferably in 10mu or less. The diamond abrasive grain, if its size in 20mu or more, increases surface roughness of a polished surface, and it is necessary to again perform polishing by machining fluid using an abrasive grain of further smaller size. While it is difficult to stably disperse the grain in the water. While a content of the polyvinylpyrrolidone is set to 0.1-50%, and if the content is less than 0.1%, an effect of stably dispersing the diamond abrasive grain in the water decreases, while if the content exceeds 50%, viscosity of the machining fluid increases. A content of the diamond abrasive grain is set to 0.1-10%.

IPC: H02P3/06
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To expand the set range of the output setting element of an internal combustion engine by releasing a limit in the second operation state, and setting an output setting element to at least one mechanical stopper. SOLUTION: When an internal combustion engine is judged to be in the idling control range (102), whether the current I flowing in a servomotor exceeds the prescribed limit value I0 or not is inspected (112). If the current I does not exceed the limit value I0 , the set target value αsoll for a setting element is determined as the function of the target engine speed Nmotsoll and the actual engine speed Nmot based on an idling engine speed controller (110), and the action signal τ is determined based on the target value (108). If the current I exceeds the limit value, the set target value (the value calculated in 110) for the setting element is increased by the prescribed value Δ (114), and the action signal is formed (108). The set target value is repeatedly increased by the value Δ as long as the current I exceeds the limit value.

Abstract: PROBLEM TO BE SOLVED: To provide a low cost, precise, and reliable probe which detects current and voltage of RF electric power to be applied to a plasma chamber and precisely detects phase angle between the supplied voltage and the supplied current. SOLUTION: An RF probe of a plasma chamber 20 picks up data of current and voltage of an RF electric power applied to an RF plasma chamber and supplies waveforms of the RF electric voltage and current respectively to mixers 30, 36.
