Filed: 1982-05-14
Abstract: PURPOSE:To prevent generation elements from being given any thermal influence by providing an inward projection near the opening of a battery exterior can in which the generation elements are installed, attaching a sealing lid to the inward projection, and irradiating laser light on the joined part so as to fuse the sealing lid and the inward projection. CONSTITUTION:An inward projection 10 is formed by seam work near the opening of a cylindrical battery exterior can 1 which also serves as a positive terminal and contains generation elements such as a positive electrode 2 and a negative electrode 4. Next, a metallic sealing lid 7 having a center penetrating hole to which a negative terminal member 6 is stuck through an insulating member 5, is placed on the projection 10. After that, laser light 12 is irradiated on the joined part between the exterior can 1 and the sealing lid 7 while rotating the exterior can 1 by means of a supporting jig 11, thereby sealing the battery by welding. As a result, since the top surfaces of the exterior can 1 and the sealing lid 7 are located on the same level owing to the inward projection 10, a secure welding can be obtained. Besides, since there is no possibility that the laser light 10 enters through a space into the generation elements contained in the battery, any thermal influence can be prevented.

Abstract: PURPOSE:To prevent a control circuit from malfunctioning and to detect an information signal stably, by providing a means of lowering the resonance frequency of a resonance circuit below the oscillation frequency of an oscillation circuit. CONSTITUTION:The means of lowering the resonance frequency of the resonance frequency below the osicllation frequency between power-on operation and signal detecting operation is provided. For example, when a switch A is closed at time t1, the oscillation circuit 1 connected to a power source 5 at the time t0 and supplied with rated electric power, but the control circuit 4 is supplied with rated electric power, but the control circuit 4 is connected to the power source 5 through a delay circuit 8 and not supplied with the rated value at the time t0, so that its output voltage is lowered almost to 0V.

Then, once the power source is turned off at t4, the oscillation circuit 1 and control circuit 4 are disconnected from the power supply.
