Abstract: PURPOSE:To prevent damage during a manufacturing process even in an electrolytic layer having sufficient rigidity and mechanically fragile strength by successively forming a dielectric layer, the electrolytic layer and a conductive layer into a recessed section and arranging anode bodies, in which oxide film layers are formed in one part or the whole of outer surfaces, on both surfaces of cathode bodies. CONSTITUTION:Mechanically fragile electrolytic layers 3 are formed into recessed sections 6 formed to one parts of an anode body 1 together with conductive layers 4, and surrounded by relative projecting sections 7. The anode bodies 1 are disposed on both surfaces of a beltlike cathode body 5. Consequently, the electrolytic layers 3 are interrupted from the outside by the anode bodies 1, and the electrolytic layers 3 need not be hermetically sealed from the outside air. Oxide film layers as a rigid insulator are formed onto surfaces except surfaces in the recessed sections 6 of the anode bodies 1, and the mechanical strength of the anode bodies 1 is increased, thus inhibiting the damage of the electrolytic layers 3 even in a manufacturing process and a mounting process to a printed board. The outer surfaces of the anode bodies 1 need not be insulated, and the cathode bodies 5 as cathode terminals and anode terminals 2 can be fast stuck along the outer surfaces of the anode bodies 1.

Title: Optical sensor
Inventor: TOJO MASAAKI
IPC: G01J1/02
Filed: 1986-04-16
Abstract: PURPOSE:To visually confirm whether an optical sensor is operated, by a method wherein the light transmitting through an optical fiber is set to visible light and the light emitted from said fiber when the optical sensor is operated is reflected to be made visible from the outside of an optical sensor housing. CONSTITUTION:A gap is provided between the leading ends of optical fibers (FB) 1a, 1b and the optical axes of both fibers are allowed to coincide using a V-groove 6 and the parts separated from the FB leading ends are fixed to the groove 6. At the time of ambient temp., the compression force of a coil spring 3 is larger than that of a shape memory alloy 4 and, therefore, a push rod 2 is pushed down and, because said rod 2 is not brought into contact with FB1b, the optical fibers 1a, 1b are coupled optically. At high temp., the compression force of the spring 3 becomes larger than that of the alloy 4 to push up the rod 2 and, at the same time, the rod 2 pushes up FB1b to optically cut off the optical fibers 1a, 1b. At this time, light is emitted from FB1b and reflected by the groove 6 to advance along light 7. Because the light emitted from FB1b is visible light, by providing a window comprising a glass plate 10 to the upper part of a housing 9, the light reflected by the groove 6 and emitted from FB1b can be visually confirmed.
