Title: Leakage flux-variable magnetic apparatus
Inventor: KAKEHASHI HIDENORI
IPC: H01F21/08
Filed: 1982-05-15
Abstract: PURPOSE:To finely control the amount of leakage flux, by providing a core constituted by an elastic ferromagnetic alloy sheet, with an external-force application means which changes the shape of the core, thereby to regulate the external force. CONSTITUTION:A ferromagnetic alloy sheet 1 made of an amorphous alloy is wound a multiplicity of turns to form a loop-like core 2. A winding 3 is provided around the core 2 to form an inductance element. A pressing device 6 has a pair of pressing members 71, 72 and pressing screws 81, 82. The regulation of the pressing screws 81, 82 allows the adjustment of the distance between the pressing members 71, 72. As the pressures F applied to the core 2 increase, the distance (d) between the opposing sides of the core 2 decreases, so that the magnetic reluctance decreases, and the leakage fluxes phi1, phi2 increase. In consequence, the inductance increases. Accordingly, the variation of the pressures F applied by the pressing device 3 permits the inductance to be adjusted.

Abstract: PURPOSE:To measure the concn. of a metal with high sensitivity and high accuracy b irradiating an electromagnetic wave in the presence of a semiconductor photocatalyst, etc., to a soln. to unite the valency of the measuring metal in the soln., then making measurement. CONSTITUTION:A sample 1 contg. Ru in a retreated soln. is fed to a vessel 10 and photocatalyst+hydrogen peroxide 2 are fed to a vessel 10 in the measurement of, for example, the concn. of Ru. Visible light or UV light is projected from a light source 7 to the sample 1 through a quartz window 5.

Title: Driving method of piezoelectric actuator
Inventor: INAGAWA MASAKO
IPC: H01L41/053
Filed: 1991-04-15
Abstract: PURPOSE:To prevent a discharge breakdown clue to humidity, even if an apparatus is continuously used at a limiting working voltage, by causing a piezoelectric element, to which pulse voltage is applied continuously, to generate heat and by driving the piezo-electric element lest water should enter the element. CONSTITUTION:For example, a rectangular wave of 150V amplitude, 0.15mS pulse width and 500Hz repetition frequency is continuously applied to a piezoelectric element to drive said element. Then, as the result of conducting a reliability test and damp-proof load life test in this state, the lifetime of the piezoelectric element can be increased by about 15 times as compared with the case of continuously applying e.g. 150V DC voltage to drive the element. Thus, when pulse is continuously applied to the piezo-electric element, heat is generated by dielectric loss, etc., and the temperature of the piezoelectric element is higher than ambient temperature so that water in the ambient atmosphere is prevented from entering a sheathing resin 4. Therefore, even if an apparatus is continuously used at a limiting working voltage, it is possible to prevent a discharge breakdown due to humidity.

IPC: B02C15/04
Filed: 1988-04-05
Abstract: PURPOSE:To finely crush a raw material such as chaff efficiently by increasing the peripheral turning velocity difference between a crushing roller and a turntable, by forming the crushing roller into an inverted conical shape increasing in its diameter toward the center direction of the turntable. CONSTITUTION:When a speed reducer is started and a turntable 3 is rotated to supply a raw material to the center part region of the turntable 3, the raw material draws a vortex like locus by the centrifugal force generated by the rotation of the turntable 3 and moved to the outer peripheral part, where a crushing roller 4 rotates, of the turntable 4. Herein, the turntable 3 is highest in peripheral velocity at the outer peripheral end thereof and becomes zero in said velocity at the center part thereof. Since the crushing roller 4 forms an inverted conical shape increasing a diameter toward the center of the turntable 3, the peripheral velocity thereof is smallest at the outer peripheral end thereof and becomes max. at the inner peripheral end and the peripheral velocity difference between them becomes large. Since the point of the peripheral velocity difference being zero is always moved left and right according to the biting state of the article to be crushed present between both of them, the raw material is crushed efficiently.
