Title: Resin composition for sealing semiconductor
Inventor: ENDO TOSHINAGA
IPC: H01L23/31
Filed: 1987-12-09
Abstract: PURPOSE:To obtain a resin composition which protects a semiconductor from humidity, by mixing a liquid epoxy resin having at least two epoxy groups in the molecule with a specified aromatic diamine. CONSTITUTION:This resin composition essentially consists of a liquid epoxy resin (a) having at least two epoxy groups in the molecule and an aromatic diamine (b) having amino groups in the p and p' positions and containing 0.1% or below aromatic diamine isomers having amino groups in positions other than the p and p' positions. It is desirable that both of the epoxy resin and the aromatic diamine have the lowest possible chlorine content. It is desirable that the chlorine content is 500ppm or below because chloride ions extracted from the resin cause corrosion of the aluminum wiring on the surface of a semiconductor chip when it is excessively high. As said aromatic diamines, those having aromatic rings such as diaminodiphenylmethane, diaminodiphenyl sulfone, diaminodiphenyl ether or modified products thereof are desirable.

Abstract: PURPOSE:To save man power in processes of putting screening residue collected from a sewage treatment factory or the like into a bag in a specified quantity after applying crushing, washing and dehydration to the screening residue and of closing the mouth of the bag by a method wherein a mouth binding device is provided so that the mouth can be closed by pulling automatically strings provided to the mouth of the bag. CONSTITUTION:An empty bag is placed in a bag holding frame 9 on a turn table 8, and the bag is set with its mouth part turned down. Loop-shaped two binding strings L are inserted through the mouth part, and each one end of the strings is engaged, through holding pieces 12a and 12b, with a hanger of a slider 14 that is provided to a position moved up to the upper part of a guide 12. As the turn table 8 turns and as the set empty bag comes to a position for putting the screening residue therein, the screening residue in specified quantity is thrown into the bag. Then an ascending/ descending frame 13 is moved down by operation of a cylinder, and the slider 14 is pushed down by a push-down device 13d of a lower arm 13b. Thereby, the two strings L are pulled downward simultaneously, closing the mouth of the bag. At the same time, the strings held between the holding pieces 12a and 12b are cut off with a cutter 13c that is lowered together with the lowering of the upper arm 13a.

Title: Electric motor control device for motor-driven power steering
Inventor: KATO YOSHIFUMI
IPC: B62D119/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To exercise sufficient performance as a motor-driven power steering without using a complicated, high-cost analog circuit. SOLUTION: An actual motor current detected by a motor current sensor 27 is converted into digital data by an analog-to-digital converter 34 and the data is taken into a CPU 35, and the CPU 35 computes the command value to a motor driving circuit 36 on the basis of the actual motor current and the target current value. The motor current can therefore be controlled without using a complicated, high-cost analog circuit. In the case of realizing motor current control by feedback control, if a means for computing the driving command value is constituted to execute filter processing for eliminating higher frequency components than cutoff frequency (=R/L) when approximating the current response of the electric motor to applied voltage with the time lag of first order, the influence of zero-order hold is reduced to realize a nonvibrating current control system.

Filed: 1994-12-15
Abstract: PURPOSE: To improve power factor of a switching regulator by approximating the waveform of the input AC current of the regulator to that of the input AC voltage with a small-sized inexpensive constitution by providing a capacitor which divides the electric current flowing through a choke coil in such a way that the capacitor is charged with the electric current and, when the voltage of the capacitor reaches the charged voltage of a smoothing capacitor, the electric charges are discharged from the capacitor. CONSTITUTION: A capacitor Cp divides the electric current flowing through a choke coil CH into nearly rectangular waveforms in such a way that the capacitor Cp is charged with the electric current which flows from the output side of a rectifier 4 to the input side of the rectifier 4 through the choke coil CH, switching transistor, and the capacitor Cp when the switching transistor is turned on and, when the charged voltage of the capacitor Cp rises and reaches the charged voltage C1 of a smoothing capacitor, the electric charges are discharged from the capacitor CH. Therefore, when the switching means is turned on, the peak value of the electric current flowing through the choke coil can be reduced, because the waveform of the current does not become a triangular waveform, but the nearly rectangular waveforms.

IPC: G06F11/00
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To securely shift a system to a fail safe processing when a fault is detected in RAM diagnosis by storing the result of RAM diagnosis in a register and directly shifting the system to the fail safe processing from the register. SOLUTION: In a step (S) 2, data on RAM being a diagnosis object are saved in a buffer. In S7, data on objective RAM are compared with temporary data. When they differ, a diagnosis result NG (the existence of fault) is stored in a prescribed register as RAM diagnosis NG in S8. In S9, data of the buffer are restored in RAM being the diagnosis object. In S10, data of RAM being the diagnosis object are compared with data of the buffer. When they differ, the diagnosis results NG (existence of fault) are stored in the prescribed register as RAM diagnosis NG in S11. The diagnosis result is read from the prescribed register and it is judged whether diagnosis result = NG (existence of fault) or not. When there is diagnosis result = NG (existence of fault), a fail safe processing is executed.

Filed: 1992-11-20
Abstract: PURPOSE:To provide a temperature of vapor at an outlet port of a desired super-heater by a method wherein an amount of coal ash is adjusted to become its heat collecting amount at a furnace pipe wall similarly to that of using coal and the coal ash is mixed with fuel heavy oil and then supplied to a boiler furnace. CONSTITUTION:Coal ash (main component: silica) within a coal ash tank 8 is supplied to a mixing device 10, becomes a mixture substance with fuel heavy oil within the mixing device 10, the mixture is supplied from a fuel supplying pipe 6 into a burner 7 and then ignited within a boiler furnace 1. In this case, a mixing amount of coal ash is adjusted in such a way that it may provide the same effect as that offered by using coal as fuel in reference to a heat collecting amount at a furnace wall pipe 2. Due to this fact, in the case that a temperature at a gas inlet port of a super-heater 3 of the boiler is detected by a temperature sensor 11 and the detected gas temperature is lower than a lower limit set value, a mixing amount of coal ash into heavy oil is increased. With such an operation as above, even if heavy oil is used at the coal burning boiler, it is possible to get a temperature of vapor at an outlet port of the desired super-heater 3.
