Title: Overvoltage detecting circuit
Inventor: YOSHIDA TOSHIHISA
IPC: H02H3/20
Filed: 1991-03-13
Abstract: PURPOSE:To set the time before the overvoltage of a power control circuit judging it as overvoltage accurately and programably with digital data. CONSTITUTION:When the voltage of a terminal 109 becomes higher than reference voltage 108, the output of a voltage comparison circuit 101 gets on a high level, and the clock from a clock generating circuit 100 is outputted from an AND gate 105. When a programmable counter 102 counts it by the number of counts being decided by setting terminal 103, it sets a flip flop 104, and though the output of a PWM circuit 107, which makes a modulated signal out of the output signal of a differential circuit 112, is input into a logical sum 106, it does not go down to a terminal 111. By the clock frequency of a clock generating circuit 100 and the number of counts being set with the external setting terminals 103, the time from the voltage rise of the terminal 109 to the output stoppage of the PWM circuit is set accurately.

Filed: 1988-02-29
Abstract: PURPOSE:To make an actual object to be sketched and a virtual image of the object in a transparent plate simultaneously viewable by a sketcher in parallel with each other without moving the transparent plate by carving mesh lines on the transparent plate on which narrow grooves at which deflection of the same direction and same angle is produced. CONSTITUTION:A transparent plate 3 is prepared by cutting off the peripheral area around the center of a Fresnel concave lens into rectangles. Then a square frame 5 is fitted to the surrounding of the plate 3 after mesh lines 4... are carved on the plate 3. When an object 6 to be sketched is viewed through the plate 3, the image of the object 6 is not obtained on the straight line 8 connecting the object 6 with the eyes 7 of the sketcher, but the virtual image 6a of the object can be been through the transparent plate 3, if the plate is moved lower than the line 8 when the plate 3 is used at a position outside the line 6, for example, at the position shown in the figure. At the same time, the real image of the object 6 can be seen along the straight line 8. Therefore, it is not necessary to move the transparent plate 3 to meet and separate from the eyes of the sketcher.

IPC: B60T8/26
Filed: 1982-03-25
Abstract: PURPOSE:To make accurate a confining pressure even when the viscosity of a brake fluid is lowered due to a temperature rise, by a method wherein an orifice provided in a passage between an inertia valve and an actuator piston is throttled to change the cross-sectional area thereof in accordance with a change in temperature. CONSTITUTION:The inertia valve 1 controls the confining pressure of the actuator piston 2 in accordance with a decelerating rate, thereby determining the decompression-starting liquid pressures of liquid pressure control valves 7, 8.

The orifice 4 consists of a component member 10 and a stepped hole 13 formed in a retainer seat 9, which members are formed of metals having different coefficients of thermal expansion. Accordingly, the cross-sectional area of the orifice is reduced when the temperature of the brake fluid is raised, so that the confining pressure is not raised even when the viscosity of the fluid is lowered.

CONSTITUTION:A graphite substrate 2 is placed in a container 1, a liquid A for precipitation and containing metallic powder 3 of a molybdenum alloy and a tungsten alloy is poured from the upper side of the container 1, excessive liquid A is discharged from a discharging outlet 4 so as to form a metallic layer 5 of the molybdenum alloy and the tungsten alloy on the substrate 2, and the layer 5 is heated at 400-1000 deg.C in vacuum or an H-containing inert gas to remove remaining organic compounds in the layer 5 and prevent oxidation and at the same time to calcine the layer 5. Then, under sealed vacuum condition, thermal isotropic compressing treatment is carried out to diffuse the metallic powder and make the metallic layer 5 dense and at the same time to bind the substrate 2 and the metallic layer 5 firmly. Owing to the lower temperature in this binding method than in soldering method, formation of carbides are greatly decreased and a long life target with high bonding strength between a substrate and a metallic layer is prepared economically.

Abstract: PURPOSE:To prevent color purity from deteriorating by providing a glass layer sealed in connected to the main face on the side of an electron gun of a shadow mask through high temperature heat treatment and setting on its surface of a coating layer with specific conductivity. CONSTITUTION:The thermal expansion coefficient of a shadow mask 5 made up of a cold rolling steel plate is about 1.2X10<-5>/ deg.C, while the thermal expansion coefficient of lead borate glass with PbOwt% of 70-80% is 0.7-1.2X10<-5>/ deg.C, generating residual tensile stress in the shadow mask and residual compressive stress in glass after sealing. Accordingly, thermal expansion in the initial stage of temperature rise of the shadow mask due to an electron beam is suppressed and a doming phenomenon is suppressed. When, however, the part of the locally high density of an electron current is generated, the doming phenomenon is generated in said part but as a coating layer 14-2 with conductivity of 10<-5>-10<-12>OMEGA<-1>m<-1> is formed on the surface of the coating layer 14-1, the negative charge, which is negatively electrified corresponding to the electron current density while being electrified on the surface on the side of the tube axis 16 of a through hole 15, deflects an orbit 10a in the direction to keep an electron beam 11 away from the tube axis 16. Accordingly, mislanding of the electron beam can be suppressed and reduced.
