Abstract: PURPOSE:To realize a baffle and a lock construction of a holder and a protective resin by arranging a recess on an end face of an opening of the holder and a protrusion on the inner circumferential surface of the opening thereof integrally by a cauking. CONSTITUTION:A temperature sensor 3 is made up of a thermistor 4, a terminal 5, a lead 6 and a holder 7. A circumferential force applied to a protective resin body 8 while the holder 7 is fixed is received mainly with a sidewall with a depth A0 of a recess 7f1 of a cauking part 7f and a sidewall of a protrusion 7f2 with a width B0. An axial tension force applied to the resin body 8 while the holder 7 is fixed is received mainly with the protrusion 7f2 with the width B0 of the cauking part 7f. The resin body 8 is baffled with the recess 7f1 and protrusion 7f2 and locked with the protrusion 7f2. Such a cauking part 7f can be realized, for example, by one process of pressing thereby lowering a machining cost.

Title: Method and device for making focal position variable
Inventor: BABA TAKESHI
IPC: G11B7/135
Filed: 1983-04-18
Abstract: PURPOSE:To vary refractive index distribution in a medium, and to make a focal position of light which is made incident to the medium variable by giving heat to the medium whose refractive index is varied by temperature, generating refractive index distribution which follows a temperature distribution in the medium, and controlling quantity of heat given to the medium. CONSTITUTION:When a current is made to flow to electrode 3, a heating resistor 4 is heated, a medium 1 being in its vicinity is heated, its refractive index becomes ununiform as shown by a line 7, and it has an operation of a lens. Accordingly, a luminous flux 8 which is made incident to a device 9 is diverged or focused locally by the lens operation, and its degree is proportional to a variation quantity of the refractive index, namely, a current flowing in the heating resistor 4. As for the device 9, when the whole body is formed by an optical transparent body, it can be used as a lens, too, and when a protective film 5 is formed as a reflecting surface, it can be used as a reflector, too. In this way, it is possible to form a variable focus device which has a good responsiveness and also does not require a part to be moved as a mechanism, therefore, for instance, it can be applied effectively to an auto focusing mechanism, etc.

Filed: 1985-03-30
Abstract: PURPOSE:To simplify a construction by limiting a voltage applied to the auxiliary winding of a transformer in a suitable drive range of the transformer and holding it, thereby reducing the power loss of a feedback control circuit. CONSTITUTION:An amplitude control IC 2 controls On or OFF a transistor Q4 in response to a voltage applied to a load 1 with the output of a voltage limiter 10 as an operating power source. When the voltage of an AC power source S drops so that the output voltage of a rectifier REC2 is lower than the Zener voltage of a Zener diode ZD1, transistors Q2, Q3 are turned OFF to stop the supply of a DC voltage. Then, when the voltage of an AC power source S increases to exceed the Zener voltage of a Zener diode ZD2, the diode ZD2 is turned ON, and the transistor Q2 forms a constant-voltage circuit. Accordingly, an excess voltage is not applied to the IC2.

Abstract: PURPOSE: To raise surface hardness of a photoconductive film, or to restrict its peeling from a substrate in order to extend its life, by forming the photoconductive film having the lamination structure of an amorphous Se-layer and an Sb 2 Se 3 -layer.  
     CONSTITUTION: Layer 3 of 0.1W0.5μ thickness is vapor-deposited on the surface of conductive substrate 1 by evaporating Sb 2 Se 3  in vacuum at 600W650°C. Amorphous Se-layer 2 is formed on layer 3 by vapor-depositing Se at about 260°C to provide a photoconductive film. The total thickness of the photoconductive film is regulated to about 60μ, thus permitting the adhesion between substrate 1 and the photoconductive film to be raised, surface hardness to be also elevated, and printing resistance to be enhanced. In order to raise only surface hardness, amorphous Se-layer 2 is formed first on substrate 1, and second, Sb 2 Se 3 -layer 3 0.5W2μ thick. In order to raise both surface hardness and adhesion, Se-layer 2 is sandwitched with Sb 2 Se 3 - layers 3. This structure is optimal for extending the life of photoconductor.
