Title: Direction detector
Inventor: YAMAMOTO TAKASHI
IPC: G01P13/04
Filed: 1979-12-14
Abstract: PURPOSE: To ensure a wide-range detection for the subject to be detected, by forming the center part of the condensing optical element such as a convex lens or concave mirror and producing two or more focuses.  
     CONSTITUTION: If the subject 8 to be detected shifts from A to B, the subject 8 is within the irradiating range l 1  of the light given from the light emitting element 3 1  and at the position A. Thus the photodetector 5 receives the reflected light of the element 3 1 . Then the subject 8 is at the overlap position of the irradiating ranges of the light emitting elements 3 1  and 3 2 , and accordingly the photodetector 5 receives the reflected light of the elements 3 1  and 3 2  each. And the photodetector 5 receives the reflected light of the element 3 2  when the subject 8 is at the position B. Accordingly, the photodetector 5 receives successively the ranges l 1 , l 1  and then l 2  and l 2  to identify the reflected light. Thus the shift of the subject 8 is decided. In such way, a detection is possible over a wide range.

Abstract: PURPOSE: To keep a pump maintain constant discharge pressure, by setting a driving mechanism which can periodically expand, to a certain position, a fluid actuating unit which is communicated with a pumping chamber and which has elastic retaining strength for changing its capacity.  
     CONSTITUTION: A fluid actuating unit 6, expandable with elastic retaining strength for changing its capacity, is fixed to and communicated with a pumping chamber 2. A equation P=A×X applies here, where X is displacement of the unit 6, P is pressure in the pumping chamber 2, and A is a constant. That is, the displacement X of the fluid actuating unit 6 is proportionate to pressure P in the pumping chamber 2. When the pressure reaches a level P=AXc, where Xc is displacement of eccentric stength A13 and Xc=X=P/A, the unit 6 is always kept expanded. This means that the discharge pressure of the pump is normally kept below a certain level, and if the pressure goes beyond the level, the eccentric cam 13 does not apply strength to the fluid actuating unit 6 and the pumping action is interrupted.
