Title: Continuous casting method by belt caster
Inventor: SUZUKI TAKAO
IPC: B22D11/06
Filed: 1987-10-13
Abstract: PURPOSE:To secure quality of a cast strip and to protect a belt by coating freon series solvent containing the specific graphite powder on surface of the belt. CONSTITUTION:In order to prevent crack caused dy solidified-shrinkage of the cast strip produced by belt caster, the solidified-shrinkage of the cast slab is needed to smoothly progress. For this purpose, the belt coating freon series solvent containing 5-30wt.% graphite powder having <=1mum average grain size on the surface is used. The graphite powder having <=1mum average grain size does not cause splash flaw and also reduces the expense, etc., for needing pulverized treatment of the graphite. Further, in order to improve the sticking with the belt and combination of the graphite powders in the coating agent, organic series resin, etc., may be added and mixed as binder. As the belt 1 in the belt caster is thermally and sufficiently protected and moisture influencing to surface of the cast strip can be perfectly removed from the belt surface, the cast slab having good surface characteristic without the splash flaw and longitudinal crack, etc., can be stably produced.

Abstract: PURPOSE:To quickly direct the television camera main body to an object by mounting the television camera main body, a half mirror and a projection means onto a universal head and projecting the video image picked up by the television camera main body onto the half mirror. CONSTITUTION:A picked-up light 32 is divided by a half mirror 16, an observed light 34 transmitted through the half mirror 16 is emitted to a camera man 30, the picked-up light 36 reflected in the half mirror 16 is emitted toward an image pickup lens 22 of a television camera main body 12. That is, the same image as that of the observed light 34 transmitted through the half mirror 16 observed by the camera man 30 is picked up by the television camera main body 12. Thus, the camera man 30 picks up an object by having only to change the direction of the television camera main body 12 in the same direction as its own visual field. Furthermore, since the video image picked up by the television camera main body 12 is projected onto the half mirror 16 by a liquid crystal display panel 18, the camera man 30 confirms the video image picked up at present on the half mirror 16.

Filed: 1984-12-11
Abstract: PURPOSE:To take a measurement at a high speed in safety by allowing a heat- resisting type optical fiber sensor to detect the quantity of a shift in position which is increased by a contactor and a speed increasing mechanism. CONSTITUTION:When the contactor 2 moves owing to the shift in the position of a moving, its quantity of displacement is increased according to the gear ratio of large and small gears 10 and 9 and the rack 8 at the side of the optical fiber sensor moves by the quantity of displacement.

Title: Variable prize ball device of pin ball machine
Inventor: UGAWA SHOZO
IPC: A63F7/02
Filed: 1988-10-14
Abstract: PURPOSE:To enhance the fan in playing with a pin ball machine by furnishing a prize ball hitting-back member to hit back a prize ball from one side of the prize space to the other side by the use of its own dropping force, and by making the motion of prize ball more complicated for prize ball under guidance of movable members. CONSTITUTION:The interval of energization/deenergization of opening/closing solenoids 65a, 65b is formed differently from the interval of energization/ deenergization of solenoid. Thereby the timing of a prize ball dropping onto a hitting-back plate 74 and the appearing timing of decoration plates 93a, 93b having defending function are varied, which gives many variations in the motion of each prize ball. A prize ball guided by opening/closing blades 53a, 53b as movable members falls in a prize space 68 to run against the hitting-back plate 74, and thereby another prize ball falling ahead the prize space 68 is jumped up up guide backward the space 68. This provides a unique locus for a falling prize ball to make its motion more complicated, which enhances the fan in playing with a pin ball machine.

Title: Input protecting circuit and semiconductor integrated circuit
Inventor: KUDO RYOTARO
IPC: H02H7/20
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To increase electrostatic breakdown strength, and to lower an input bias current by clamping the voltage of an input terminal approximately at a first source voltage, when a voltage which exceeds the first source voltage and is lower than a voltage which turns a first protective diode on, is applied to the input terminal. SOLUTION: If a voltage higher than a first source voltage is applied to an input terminal t2, and the MOSFET M1 of a clamping means 24a is turned on, the voltage of the input terminal t2 is clamped at the sum voltage of a threshold voltage and the source voltage Vdd of the MOSFET M1. When an abnormal voltage is applied long and its voltage value is especially large, a first protective diode D1 is turned on, a current flows from the input terminal t2 to the source voltage Vdd, the voltage of the input terminal t2 is clamped at the sum voltage of the source voltage Vdd and a forward bias voltage of the protective diode, and breakdown of elements is prevented. Consequently, a high-reliability circuit which does not malfunction easily is obtained without lowering strength against electrostatic breakdown.

Filed: 1985-11-20
Abstract: PURPOSE:To prevent a parasitic thyristor from latching up by providing a diode element connected at its cathode side with a common connection point with the drain of a P-channel transistor at its anode side in series-connection P- and N-channel transistors. CONSTITUTION:A P-channel transistor 3 is connected in series with an N-channel transistor 4 in an inverter output circuit of CMOS structure. A diode 5 is connected at its anode side with the drain of the transistor 3, and at its cathode side with the drain of the transistor 4 and an output terminal D. When a low level input is applied to an input C in this manner, the output D becomes a high level, the output D becomes a low level when a high level input is applied to the input C, and the circuit operates as an inverter. When a voltage higher than the power voltage Vcc is input from the output D due to a noise, the diode 5 prevents a P-N junction from becoming forward, thereby preventing a parasitic thyristor from latching up.
