Title: Bias circuit
Inventor: TAKAHASHI YASUSHI
IPC: H03M1/74
Filed: 1991-04-01
Abstract: PURPOSE:To reduce current consumption without deteriorating the operating speed by connecting a resistor and three MOS transistors (TRs) in series, dividing a power supply voltage so as to generate a bias voltage thereby outputting the voltage via a source follower comprising the MOSTRs. CONSTITUTION:The circuit is provided with a MOSTRQ2 whose gate electrode and drain electrode are connected to a power supply via a resistor 1, a MOSTRQ3 whose gate electrode and drain electrode are connected to a source electrode of the TRQ2, a M0STRQ4 whose gate electrode and drain electrode are connected to a source electrode of the TRQ3 and whose source electrode connects to ground, a MOSTRQ6 whose gate electrode connects to the power supply and whose gate electrode is connected to the gate and the drain electrode of the TRQ2, a MOSTRQ5 whose gate and drain electrodes are connected to the source electrode of the TRQ6 and a M0STRQ7 whose gate and drain electrodes are connected to the source electrode of the TRQ5 and whose source electrode connects to ground. Since the TRQ6 acts like a source follower, the output impedance is set low and an output voltage fluctuation by a load current is suppressed.

Title: Fine electric discharge device
Inventor: MIZUTANI TAKESHI
IPC: B23H1/00
Filed: 1989-03-20
Abstract: PURPOSE:To variably set the floating capacity in an RC discharging circuit optionally by providing an adjusting means provided in a work tank and for optionally changing the gap between the work tank bottom face and a placing base for fitting the body to be worked or an electrode forming block. CONSTITUTION:The distance between the work tank 6 bottom face and a placing base 9 to which the body 10 be worked or an electrode forming block is fitted is adjusted by an adjusting means 7. The floating capacity can be changed optionally and selectively. In this case, due to the capacitor 14 of an RC discharging circuit 12 being variable in its capacity, discharging is executed by adding both, or discharging can be performed with the small energy of a proper floating capacity only.

Title: Car washing system
Inventor: YOSHIKAWA MASANAGA
IPC: B60S3/06
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To properly operate an upper surface treating device for a car body without reducing a relative moving speed even during high-speed washing by controlling the relative moving speed according to the length of set washing time and controlling the vertical moving speed of the upper surface treating device according to a detected car shape and the set relative moving speed. SOLUTION: Traveling speeds for low-speed washing time and high-speed washing time are inputted and set by means of the value of a power supply frequency supplied to a washing system traveling motor. For high-speed washing, the system is moved by a set speed of about 60 Hz and, if the inclination of a car shape detected by a car shape detecting means is equal to about 20 deg. or lower, the vertical moving speed of an upper surface washing brush exceeds about 20 Hz and about 20 deg., and if the inclination is equal to about 30 deg. or lower, the speed is about 40 Hz, and if horizontal, the speed is maintained. Also, for low-speed washing, in addition to traveling at a set speed of about 30 Hz, as in the case of high-speed washing, a vertical movement is controlled at a speed predetermined according to the traveling speed of the washing system and the inclining angle of the car body.  Thus, safe washing is carried out without deteriorating washing performance or any parts remaining unwashed.
