Title: Vertical shafat water turbine
Inventor: SHINOHARA MORIMICHI
IPC: F03B3/02
Filed: 1985-06-19
Abstract: PURPOSE:To dispense with a branch pipe, an effluent valve and an effluent pipe to reduce the volume, period and cost for building a power plant by moving a runner to provide effluence through a water turbine when it is stopped. CONSTITUTION:A runner 4 slidably engages axially a flange 7a of a spindle of a vertical shaft water turbine with a key coupling or the like. To the connecting plate 6 of the runner 4 is connected a piston 9 in a hydraulic cylinder 8. Also, above the runner 4 is formed a space 5a capable of receiving the runner 4. And when a guide vane 3 is closed and the water turbine is stopped necessitating effluence, oil pressure acts on the interior of the hydraulic cylinder 8 to move the runner 4 to the space 5a and then the guide vane 3 is opened to permit the effluence without passing through the runner.

Title: Power supply protective circuit
Inventor: MUKOHARA TAKUYA
IPC: H02H3/08
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To enhance the function for preventing smoking/firing due to tracking (carbonization) phenomenon of material at each part by providing a function for interrupting overcurrent even when a high voltage leak takes place in a high voltage generating circuit having failed intermittent oscillation circuit. SOLUTION: When a current of a specified level or above flows through a first resistor R30, a second transistor Q31 conducts and a thyristor function section 50 operates to conduct a third transistor Q32. Consequently, conduction of a first transistor Q30 is interrupted. Even if conduction of the second transistor Q31 is interrupted subsequently, operation of the thyristor function section 50 and conduction of the third transistor Q32 are sustained.

Abstract: PURPOSE:To enable the very high sensitive development, without entirely depressing the contrast by developing the resist material with a solvent mixture composed of a cyclic ether which has a four-six membered cyclic ring structure and is a good solvent for the titled resist, and a poor solvent for the titled resist. CONSTITUTION:In the development of the positive type radiation resist material composed of a copolymer obtd. by copolymerizing alpha-methylstyrene or its derivative, and an another comonomer capable of forming the positive type resist material, the mixed solvent composed of the cyclic ether which is the good solvent for the prescribed copolymer and has the four-six membered cyclic ring structure, and the poor solvent for said copolymer, is used to the developer. The more content of the cyclic ether which is the prescribed good solvent is high, the higher sensitive development becomes possible, but, the film of the unexposed part becomes remarkably thin, and the gamma-value of the titled resist is also reduced. On the contrary, when the content of the prescribed poor solvent in the resist is too large, the sensitive of the titled resist depressed. Thus, the mixed ratio of the cyclic ether of the prescribed good solvent and the prescribed poor solvent is a range of 5/95-95/5 vol. ratio, preferably 10/90-90/10 vol. ratio.

Filed: 1986-06-11
Abstract: PURPOSE:To detect the signal only of torsional vibration, by setting a reference pulse train counting the rotational irregularity of a rotary shaft to be a reference signal synchronous to the average number of rotations of the rotary shaft. CONSTITUTION:Electromagnetic pickups 2, 3 output pulse signals A1, A2 with the revolution of a gear 1 at each time when the teeth t1, t2, t3... traverse the front ends of said pickups. A pulse signal A' having a time width wherein an arbitrary tooth passes between the pickups 2, 3 is formed on the basis of the signals A1, A2 by a flip-flop (FF) circuit 7. The frequency of the signal A2 is divided in synchronous relation to the pulse of the signal A1 by the circuit 7 to be set to 1/2 to obtain the signal A' wherein pulses based on teeth t2, t4... are erased. Next, the signal A' of the circuit 7 is set to a gate signal and the pulse count value N of the reference pulse train signal B' contained in the pulse width of said gate signal is counted according to a predetermined formula by a counter 8. Further, the reciprocal of the value N is calculated by a reciprocal device 9 and converted by a D/A converter 10 to be outputted as an analogue output signal C. By this constitution, when torsional vibration is generated during the rotation of a rotary shaft at a constant speed, instantaneous angular velocity beings to vary around average angular velocity at the cycle of torsional vibration and this variation component is calculated as torsional vibration angular velocity.
