Title: Pilot hydraulic system for operating derectional control valve
Inventor: DATSUMI AKIRA
IPC: F15B11/00
Filed: 1986-12-27
Granted: 1990-03-19
Abstract: A variable displacement hydraulic pump (14) is driven by an engine (12).  A pump regulator (15) controls the displacement volume of the pump. At leaset one actuator (11,17,43,50) is driven by pressurised fluid delivered by the hydraulic pump.  The number of engine revolutions can be controlled or altered between different maximum values by altering devices (18,38,41,13,52).  The maximum displacement volume can be altered between maximum values. The maximum revolution number and maximum displacement volume altering devices are controlled by the information providers (20, 25,60,36,40,44,54,55).  A product of the maximum displacement volume and the number of revolutions becomes at a constant always at the same time when the maximum displacement volume of the pump is varied in response to an output signal of the providers, where a change in the quantity of pumped liquid can be avoided when the maximum displacement volume of the pump is altered.

Granted: 1996-04-23
Abstract: This potentiometer presents a parallelepiped casing having a quadrangular plan and is provided with recesses for the coupling of the connecting terminals which are definitely joined by plastic deformation of the pivots of the said casing. It also incorporates by-pass holes for the said terminals towards the ends of the resistive plate, as well as recesses for securing the collector by deformable flanges existing at the edges of the said collector. The central hole of the collector is flanged, constituting a bearing for the rotor-actuated cursor, which incorporates at diametrically opposed areas thereof, as contacting elements with the resistive plate and the collector, pairs of countersunks determining rounded supports on the said elements. These elements are assembled automatically and continuously. The terminals form part of a continuous band on which they are duly stamped, as occurs with the cursors and the collectors. Each terminal-casing-resistive plate subassembly, on the one hand, and each rotor-cursor-collector subassembly, on the other, is firstly mounted, maintaining the continuity through the said bands. Finally, one subassembly is secured to the other and the bands which maintained the continuity thereof are eliminated. The resistive plate is obtained from an electroisolating substrate on which a resistive paint is firstly applied and then a silver glaze, with intermediate drying phases in respective furnaces.

Abstract: 본 발명은 일반식 Pb 1-x La x (Zr y Ti 1-y ) 1-x/4 O 3 (식중 X,Y는 0.1 또는 1보다 작은 소수)으로 표시되는 Pb함유 강유전체로 이루어지며, 그 유전체에 함유되는 알칼리금속불순물의 함유량이 1ppm이거나, 유전체에 함유되는 알칼리금속불순물의 함유량이 0.1ppm이하이고, U, Th의 합계함유량이 10ppb이하인 것을 특징으로 하는 초고순도 강유전체박막을 개시한다. 
     이 초고순도강유전체박막은 누설전류의 레벨이 대단히 낮으므로, 적외선센서, 압전필터, 진동자, 레이저변조소자, 광셔터, 커패시터막, 불휘발성기억장치 등에 적용할 수 있다.
