Title: Insulation-circulation type hot water supplier
Inventor: SHIROTA TETSUYA
IPC: F24H1/10
Filed: 1987-09-02
Abstract: PURPOSE:To improve follow-up property to the reduction in set temp. by a method wherein when actual hot water temp. is sufficiently higher than the set temp. at the change time of the set temp. for hot water supply, a circulation pump is driven to circulate the hot water and the circulation amount is larger than that at insulating operation with the OFF condition of a heater. CONSTITUTION:When set temp. for hot water supply is sufficiently reduced in an insulation mode and the hot water temp. is higher than a new set temp. by a constant temp. beta, e.g. 5 deg.C, a circulation pump 51 is ON with the OFF condition of an electric heater 53 and a control valve 5 for the water amount is widely opened. Thereby, a large amount of hot water is circulated to reduce the hot water temp. by the use of heat radiation during circulation. This opera tion is continued until the hot water temp. becomes lower than the set temp. + the constant temp. beta. By this constitution the follow-up property of the hot water supply temp. can be improved even though the set temp. is sufficiently reduced.

Title: Drive controller for motor vehicle
Inventor: SHIBATA AKIRA
IPC: B60L7/12
Filed: 1989-08-28
Abstract: PURPOSE:To maintain response characteristic and reduce ripple during drive control operation and to prevent impact upon abrupt brake operation by controlling the integration time constant of an integration circuit according to the opening of an accelerator and controlling the integration circuit such that the integration time constant for full close of the accelerator can be obtained upon full close of the accelerator. CONSTITUTION:An integration time constant control section 12 controls the integration time constant of an integration circuit 9 to increases as the opening of an accelerator decreases. An accelerator full close detecting section 21 controls the integration circuit 9 such that the integration time constant for full close of the accelerator can be obtained upon full close of the accelerator regardless of the operating condition of the integration time constant control section 12. By such arrangement, two contradictory requirements, i.e. retention of response characteristic and reduction of ripple during drive control operation, can be satisfied and impact due to abrupt variation of driving force can be prevented upon abrupt brake operation.

Title: Electric discharge machining device
Inventor: NABEKURA NOBUYOSHI
IPC: B23H1/02
Filed: 1984-10-23
Abstract: PURPOSE:To restrain the consumption of an electrode to an extremely low value even though water or machining liquid containing water as a main component is used, by ceasing the supply of machining pulses in accordance with the result of detection of electrolytic current generated under electrolytic action in an electric discharge gap. CONSTITUTION:An electric discharge machining device 1 is provided with a machining device body 2 and a machining pulse power source 3. When electrolytic action occurs during electrical discharge in the electrical discharge machining gap 12 of the electric discharge machining device 1, the current value I is increased due to electrolytic current, exceeding a predetermined value. As a result, the level of a detection voltage Vd exceeds the level of a reference voltage Vr, and therefore, the output power voltage level becomes high. Accordingly, a monostable multivibrator 23 is triggered to lower the level of an inhibiting signal for a short time, and therefore, an AND gate 19 is closed. Accordingly, a switching transistor 15 is deenergized to cease the electrolytic action in the machining gap 12. With this arrangement, it is possible to prevent electrolytic current from being fed to the electrical discharge machining gap 12, by means of a machining pulse supply control circuit 20.

Abstract: PURPOSE:To obtain adhesive tape which provide low adhesion in an early stage, and what is more, does not increase its adhesive power even if it is left over for long time after pasted by defining its early stage adhesive power with a mirror wafer within a specific range with the adhesive tape which uses a pressure sensitive adhesive which contains a specific surface activator and cross-link agent. CONSTITUTION:An acrylic group resin water emulsion type adhesive agent-compounding solution which includes a specific water-soluble organic compound, a specific interface activator and a specific cross-link agent is prepared. The compounding solution is coated and dried on the top of the base material film, which provides adhesive tape provided with a pressure sensitive agent layer whose adhesive power with a mirror wafer ranges from 50 to 450g/25mm. This construction makes it possible to obtain a reverse side grinding adhesive tape for semiconductor which provides strong early stage adhesion to a semiconductor mirror wafer and what is more, minimizes an increase in its adhesive power with the lapse of time. When the adhesive tape is applied to the surface of the semiconductor wafer to grind the reverse side of the semiconductor, this construction makes it possible to protect the semiconductor wafer from damage and separate the tape from the wafer with ease even if it is left over for about ten days and enhance workability.
