Filed: 1988-09-20
Abstract: PURPOSE:To make an oil pressure same as the atmospheric pressure and prevent the generation of a cavitation by making a filter shape conical and exposing a part of the filter from a liquid surface in a reservoir provided with the filter which can filter oil flowing from a suction pipe to a delivery pipe. CONSTITUTION:A returning oil enters in a vessel 10 from a suction pipe 20, being led in a circumferential direction by a guide 21 and then flows along a cylindrical part 12 so as to generate an eddy in the vessel 10. The eddied oil is led to the inner space of a filter 17a through the filter 17a and sucked in the suction side of a pump through a delivery pipe 24 connected to the vessel in the radial direction of the cylindrical part 12. While, holes 42 and grooves 43 are formed on a gum packing 40 located under a cap 41 and as the oil staying inside the filter 17a flows outside the vessel 10 through a filter 17b thereby, its pressure is almost same as the atmospheric pressure. Consequently, the generation of a cavitation becomes difficult regardless of any change in the viscosity of oil.

Inventor: YAMAZAKI SHUNPEI
IPC: G02F1/136
Filed: 1995-08-22
Abstract: PURPOSE: To provide a thin-film transistor(TFT) which is lessened in leakage current. CONSTITUTION: Electrodes formed to a shape approximately resembling the outside shape of the TFT is arranged concentrically on an active layer 504 consisting of a semiconductor film. The gate electrode 502 and the electrode 503 of the shape lacking a part of a torus are so arranged as to enclose the outside of circular electrode 501.

Either one of the electrode 501 and the electrode 503 is formed as a source electrode and the other as a drain electrode.  As a result, the edges of the active layer 504 do not exist on a line connecting the source electrode and the drain electrode and, therefore, the constitution that the drain electrode and the source electrode are not shorted by the gate electrode is obtained. Consequently, the leak current is lessened.

Title: Charge pump for semiconductor substrate
Inventor: PROEBSTING ROBERT J
IPC: H01L27/108
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a charge pump for producing a negative substrate bias in a CMOS integrated circuit. SOLUTION: A low voltage current source 24 generates low voltage signals to feed a variable frequency oscillator 28. The low voltage signals are at a slightly higher voltage until a negative substrate bias is achieved. The oscillator 28 operates at a low frequency for low power consumption when no charge pumping is needed and at a higher frequency when charge pumping is needed or when charge pumping is in fact needed or when charge pumping is most likely to be needed. The oscillator 28 controls a timing signal generator 24 which controls the overall operations of a charge pump system to generate timing signals. A comparator 52 compares the output of a voltage conversion circuitry 44 which converts the substrate voltage from its negative value to a positive, value with a reference voltage.  If the substrate voltage is above the desired level, the comparator 52 generates a pump activating signal to a pump signal generator 64 which, in turn, generates a necessary signal to make a charge pump 80 operate.
