Title: Power circuit for starting horizontal oscillation
Inventor: TSUDA HIDETOSHI
IPC: H04N3/16
Filed: 1979-01-13
Abstract: PURPOSE:To make it possible to start horizontal oscillation even when an AC voltage increases gradually, by actuating a horizontal driver circuit by making use of a blocking oscillation output. CONSTITUTION:To point B, a DC voltage is applied by resistance R1 and capacitor C4, and transistor Q1 is applied at its base with a constant voltage divided by resistances R2 and R3. In the beginning when the DC voltage is applied from point B via capacitor C5, the emitter potential of Q1 is equal to a potential at point B, but once capacitor C5 is charged with the time constant of resistance R4 and capacitor C5, it falls gradually by a value equivalent to the charge. With the emitter potential of Q1 decreases below the base potential, Q1 conducts to flow a collector current through the primary winding of transformer T5, and it is positively fed back via capacitor C6, so that Q1 will momentarily be saturated to charge capacitor C5 via Q1. With capacitor C5 charged, the emitter potential of Q1 increases up to the potential of point B and Q1 turns OFF. Although this operation is repeated, a voltage induced across the secondary winding of transformer T5 is rectified and smoothed by diode D1 and capacitor C1 and then supplied as the starting power supply of horizontal oscillation driver circuit 3.

Abstract: PROBLEM TO BE SOLVED: To allow an electrolytic reaction to proceed rapidly in high yield and to easily obtain a product reflecting the physical properties such as the granular shape of a raw material by using a porous body such as a foamed body having a three-dimensional structure as a working electrode and using a raw material insoluble or sparingly soluble in an electrolyte or a fused salt. SOLUTION: A porous body such as a metallic-nickel foamed body having a three-dimensional structure is used as a working electrode, a powder of nickel hydroxide, or the like, insoluble in an electrolyte such as an. aq. sodium hydroxide soln. is dispersed as a raw material in the electrolyte, and a constant voltage is impressed between the working electrode and a counter electrode to conduct electrolysis. In this case, the average grain diameter of the aggregated particles of a solid material as the reactant is made smaller than the pore diameter of the working electrode, and the reactant is easily infiltrated into the porous body by agitating the electrolyte. Consequently, the contact interface of the reactant on the working electrode is increased to promote the synthetic reaction, and the reaction product such as nickel oxyhydroxide is rapidly obtained as a granular body having the same shape as the raw material.

Title: Fluid transport pipe
Inventor: MOTODA KENRO
IPC: B65G27/00
Filed: 1985-01-18
Abstract: PURPOSE:To transmit a signal with good responsibility even if fluid has viscosity and a pipe has a small bore by mounting an ultrasonic and a pipe has a small bore by mounting an ultrasonic vibrator on the outer surface of the pipe formed by an elastic body, and driving the vibrator to generate a surface progreeive elastic wave in the inner surface of the above pipe. CONSTITUTION:Ultrasonic vibrators E are mounted on the outer periphery of a fluid transport pipe 1 formed by a pipe made of an elastic body. When the vibrators E are driven to propagate the progressive wave of the longitudinal wave and transversal wave of ultrasonic wave to the pipe 1, fluid contacting the iner wall of the pipe 1 is caused to move. Thus, though usually the velocity of flow of the fluid contacting the inner wall is slower than that of fluid in the other portions due to frictional resistance between the fluid and the pipe 1, the usual velocity of flow is increased by action of the surface progressive elastic wave. Therefore, as a whole, the fluid is reduced in resistance to increase the velocity of flow.

Abstract: PURPOSE:To attain lean-combustion where fuel concentration of premixture air is thinned to the utmost, and suppress generation of nitrogen oxide so as to maintain a stable lean combustion condition, since reduction in nitrogen oxide included in combustion exhaust gas in the premixture combustor of a gas turbine and the like is required keenly. CONSTITUTION:Premixture air-fuel concentration of a mixing chamber 8 is detected, and the exhaust hole 34 of a local fuel leading-in mechanism is provided on the auxiliary chamber 4 side outlet end of the mixing chamber 8. The amount of local fuel supplied from the exhaust hole 34 is adjusted moderately, and thereby, pre-mixture air fuel concentration of the outlet of the mixing chamber 8 is concentrated in a local part. It is thus possible to maintain a stable combustion condition even if secondary premixture air is in a lean side. As a result, it is possible to suppress forming of nitrogen oxide in combustion exhaust gas, and to widen a pre-mixture combustion range toward fuel concentration lean side especially.
