Title: Auto-focusing device
Inventor: OGASAWARA AKIRA
IPC: G02B7/28
Filed: 1981-08-20
Abstract: PURPOSE:To prevent malfunctions such as the hunting operation of a photographic lens, by driving the lens in accordance with the optical image output of a photoelectric element array which is generated in the state where the lens is stopped practically. CONSTITUTION:Optical image signals are inputted successively to an operation processing circuit 4 to generate a strobe pulse P2 together with a control output P1. When the pulse P2 is applied to a controlling circuit 9, the controlling circuit 9 inhibits the read of the control output hereafter and permits the driving of a motor M. A lens 7 is driven to the focus position in accordance with the control output. When a focus error signal and a lens displacement quantity signal have a prescribed relation, the controlling circuit 9 stops the driving of the motor and permits the read of the control output. The operation processing  circuit 4 operates the control output on a basis of the optical image output in  the state where the movement of the lens is stopped. Consequently, malfunctions  such as the hunting operation of the lens are prevented.

Abstract: PURPOSE:To relax the concentration of a stress due to the elongation of a pattern circuit conductor and to prevent the fracture of the conductor by a method wherein the pattern circuit conductor is formed of a material whose elongation percentage is a prescribed value or higher. CONSTITUTION:A prepreg which has been impregnated with a glass cloth epoxy resin as an insulating substrate 1 and copper foils whose elongation percentage is 10% or higher at room temperature and whose elongation percentage is 10% or higher at 180 deg.C are pressurized and heated; and a copper-clad laminated board is formed. Then, ultraviolet-hardening etching resist films are laminated on both faces of the copper-clad laminated board; a photomask in a desired pattern is brought into close contact; and the board is irradiated with ultraviolet rays and developed. Thereby, a desired etching pattern is formed. After that, inessential copper foils are etched and removed; and a desired circuit pattern circuit conductor 3 is formed. Since the pattern circuit conductor 3 is formed in this manner, the concentration of a stress due to the difference in a coefficient of thermal expansion can be absorbed and dispersed by the elongation of the pattern circuit conductor. Even when the pattern circuit conductor is made thin, it is not subjected to a stress fracture, high connecting reliability is ensured and a fine circuit can be formed.

Abstract: PROBLEM TO BE SOLVED: To provide a secondary battery with high capacity and high charge and discharge efficiency by covering a layer consisting of carbon by a method of subjecting the surface of a negative electrode active material consisting of a Li-storable alloy to CVD treatment or covering it with an organic matter followed by baking. SOLUTION: The surface of a negative electrode active material using a Li-storable alloy is covered with a layer consisting of carbon. To uniformly cover the layer consisting of carbon, CVD treatment is effectively used. The layer consisting of carbon is formed on the surface of the alloy particle by covering the alloy particle surface forming the base with an organic material followed by baking. The Li-storable allay means a compound consisting of two or more metals, or a metal and a half metal. Of these Li-storable alloys showing high storability to Li, alloys including Al, Ge, Si, and Zn in the composition particularly have capacity and energy density higher than carbon negative electrode active materials, and are also excellent in cycle characteristic when they are repeatedly charged and discharged.
