Filed: 1981-01-31
Abstract: PURPOSE:To enable to control the water level in a stable manner, by providing two water-level responsive switches in a high and a low stages, and keeping a water head by driving a pump through operation of the two switches. CONSTITUTION:A water-level responsive switch menas shown in the drawing comprises a first water-level responsive switch 7 in addition to a second water- level responsive switch 10. These two switches 7, 10 are disposed with a level difference to have a water head (H2-H1) corresponding to a capacity 60% or more of the content of a water drawing hose 25. Therefore, if air is drawn into the pump, the level of water in a water storage tnak 2 does not lower to the level H1 where the first water-level responsive switch 7 is set into operation, and the switch 7 continues to operate for operating a pump 13 continuously, so that the water level can be controlled in a stable manner.

Abstract: PURPOSE:To permit the detection of racing and sliding surely, by a method wherein the output of a rotating number changing rate operating means is inputted into a plurality of comparison means while the outputs of these comparison means are inputted into corresponding time limit means respectively. CONSTITUTION:A changing rate operating means 41 inputs the output signal Fr of a rotating number detector to operate the changing rare of the number of rotation of a motor and output it to a racing and sliding detecting means 42. Respective comparison means 421a-421c output predetermined signals when the values of changing rate of the number of rotation operated by the changing rate operating means 41, become larger than respective racing and sliding detecting levels Fa-Fc. Then, time limit means 422a-422c, provided so as to correspond to respective comparison means, output signals SLa-SLc when the predetermined signals, outputted from respective comparison means, are continued longer than predetermined times Ta-Tc. An outputting unit 423 inputs the output signals SLa-SLc, outputted from respective time limit units and outputs a racing and sliding detecting signal SL.

Abstract: PURPOSE:To control the speed and direction of rotation by comparing the outputs of a cantilever made of a light-transmissive member, a light emitting element provided to the base of the cantilever, and two photodetecting elements provided opposite the tip of the cantilever. CONSTITUTION:A video disk 1 rotates and a scanning stylus 13 moves as shown by an arrow A. A light-transmissive cantilever 11 slants around a damper 12 as shown by an arrow A through a chip holder 14. Light from a light emitting element 15 is projected on two pieces 23a at right angles, transmitted in the cantilever 11 by repeated nearly-total reflection, and emitted from two pieces of a wedge 23b to reach photodetecting elements 16a and 16b. When the cantilever 11 slants as shown by the arrow A as the video disk 1 rotates, the quantity of light incident to the photodetecting elements 16a and 16b varies. The output voltages of the photodetecting elements 16a and 16b are applied to a comparator 17, and their difference in output voltage is applied through a low-pass filter 18 and a hysteresis comparator 19 to a motor driving circuit 20 which controls the turning speed, etc., of an arm leading motor 21.

Abstract: PURPOSE:To prevent damage of a solder balls and to make it possible to control the thickness of a brazing filler metal that is present on a sealing surface, by providing a plurality of projections on at least one sealing surface of a cap and a substrate. CONSTITUTION:A tungsten metallized layer (not show) is formed on a sealing surface 1d of a substrate 1 and a sealing surface 2a of a cap 2. A solder layer is deposited to a specified thickness. A semiconductor pellet 3 is mounted on the substrate 3 through a plurality of solder balls 3a by a solder ball bonding method and the like. A solder layer constituting a brazing filler metal is deposited on the back surface of the pellet 3 to a specified thickness. When the cap 2 is pushed to the substrate 1 in a specified temperature atmosphere, the solder layer that is deposited on the back surface of the pellet 3 is fused into the brazing filler material 3b. Thus, the pellet 3 is connected to the inner surface of the cap 2. At the same time, the solder layer on the sealing surface 2a and the sealing surface 1d is fused so as to become a brazing filler metal 4. Thus, the cap 2 and the substrate 1 are sealed. Since projections 2b are provided here, the thickness of the brazing filler metal 4 can be made approximately equal to the height of the projections.

Inventor: ITO YUTAKA
IPC: H03K17/16
Filed: 1989-01-24
Abstract: PURPOSE:To suppress the transient overvoltage of a fly-wheel diode at the time of restoring an inverse characteristic and to allow the withstand voltage selection of a diode to be appropriate by installing the diode generating a bypass line for discharging accumulated energy in a wiring inductance on the output side of a switching element.

When the transient voltage of the diode Dw corresponding to the ON-operation of te switching element 2 at the time of restoring the inverse characteristic is superposed on a DC power voltage Ed and inversely impressed on the diode Dw, a charge current Isn with respect to the capacitor Cn is conducted in correspondence with the difference voltage of the superimposed voltage and the normal terminal voltage of the capacitor Cn. Then, the accumulated energy of a wiring inductance 4 part is discharged. Thus, the abnormal rise of transient backward electromotive force is controlled and the enhancing the withstand voltage of the fly-wheel diode is eliminated.

Title: Electron beam exposure
Inventor: SAITO MASAYUKI
IPC: H01L21/027
Filed: 1989-01-24
Abstract: PURPOSE:To improve the dimensional stability of a pattern in a deflection field by obtaining a dosage at which the dispersion in pattern dimensions is made minimum beforehand, and exposing resist applied to a substrate to said dosage using an electron beam. CONSTITUTION:On the current density curve P1 of an exposing part at the central part in a deflection field, the current density increases with the change in dosage, but the beam width is hardly changed. On the current density curve P2 at the peripheral part, both the current density and the beam width are changed by changing the dosage owing to the deviation of a focal point based on spherical aberration. Then, various kinds of dosages for the pattern width at each point of the deflection field are obtained, and the dosage at which the dispersion S in dimension at each point becomes minimum is obtained. Each deflection field of many substrates is exposed based on the obtained dosage. Thus the exposure of patterns having excellent dimensional stability can be performed.

Title: Fuel injection system for internal combustion engine
Inventor: MIZUNO HIROHISA
IPC: F02M69/04
Filed: 1981-02-03
Abstract: PURPOSE:To reduce the variation in the concentration of mixture gas by a construction wherein injected fuel is made to collide with a throttle value within the range of 1/3-2/3 of the radius thereof irrespective of the opening of the throttle valve. CONSTITUTION:When the radius of a throttle valve 7 is represented by r, the fuel injecting direction of a fuel injection valve 17 is arranged to be directed toward r/3-2r/3 from the center of rotation. Since the fuel is injected upward and leftward of the valve 7 in the idling operation of an engine in which the opening of the valve is small in this manner, the fuel is generally uniformly spread to the entire surface of the valve 7 slightly inclined and is flowed from the periphery of the valve 7. At this time, the fuel is finely atomized by the air stream which passes through the peripheral gap between the wall surface of the suction gas passage and the valve 7, thereby providing uniform concentration mixture gas.
