Title: Actuator driving device
Inventor: FUJIWARA AKIHIRO
IPC: G03B5/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To allow an amplification means amplifying output from a difference arithmetic means to have the function of an amplification means required by the difference arithmetic means, to reduce the number of parts and to realize the reduction of the cost and saving space by arranging a phase compensating means between a state detection means and the difference arithmetic means. SOLUTION: At least one of phase compensation circuits 17 is arranged between a displacement amount detection circuit 16 and a difference arithmetic circuit 11. A difference between a target signal supplied from a shake detection sensor and a detection signal outputted from the circuit 16 through the circuit 17 is arithmetically calculated by the circuit 11, amplified in terms of power by a power amplification circuit 13 at a next stage and supplied to a driving circuit 14. A variable apex angle prism(VAP) 15 is displaced in accordance with power by which it is driven, and a displacement amount is detected by the circuit 16, compensated in terms of phase by the circuit 17 and supplied to the circuit 11. Thus, the positional control of the VAP 15 is performed so that the difference between the target signal and the detection signal may be zero.

Title: Driving unit for retractable head lamp
Inventor: FUKAE TOORU
IPC: B60Q1/05
Filed: 1982-08-25
Abstract: PURPOSE:To make a head lamp driving unit compact and light as the whole by rotating a head lamp from its stowage position to illuminating position by using as driving force the force of either a shape-memorizing-alloy coil spring or an ordinary coil spring. CONSTITUTION:No.2 coil spring 18 is formed by using a shape-memorizing-alloy spring which enables that the spring force of No.2 coil spring is smaller than that of No.1 coil spring 17 at the temperature lower than the prespecified temperature but it becomes greater than that of No.1 coil spring 17 when the temperature becomes higher than the prespecified temperature. When No.2 coil spring 18 is electrified and heated while a head lamp 3 is in the stowage position, the spring force of the spring 18 becomes greater to compress No.1 coil spring 17, and a slider 11 slides on a guide shaft 9, thereby also making a rack 12 travel. Movement of the rack 12 rotates No.1 and No.2 pinions 13 and 16. Thus, a sector-gear 2 rotates a rotating shaft 1 in the direction of arrow mark ''a'' so that the head lamp 3 moves up from the stowage position to the illuminating position.

Title: Molten carbonate fuel cell
Inventor: HADO KAZUHITO
IPC: H01M4/86
Filed: 1986-06-23
Abstract: PURPOSE:To increase corrosion resistance of metal bulk of a cathode by using a foamed metal comprising nickel-chromium alloy in a cathode united with a current collector. CONSTITUTION:A nickel-chromium alloy is used in a foamed metal serving as a cathode in which oxidizing gas can freely diffuse through open pores of porous electrode substrate and a current collector is practically unnecessary. By utilizing strong oxide film of chromium, the foamed metal comprising nickel- chromium alloy is used in the cathode to increase corrosion resistance. Although the surface of the foamed metal comprising nickel-chromium alloy is oxidized and doped with lithium, the bulk keeps metallic state, and the skeleton can retain shape and strength. Thereby, the electrode united with current collector can be made thin, the construction is made simple, and the cell performance is stabilized for a long time.

Title: Injection mold for thin molded article
Inventor: YAMAGISHI HIDEKI
IPC: B29C45/37
Filed: 1978-11-28
Abstract: PURPOSE:To reduce the amount of resin used and facilitate afterworking and mold release upon molding by gradually enlarging the gap of a cavity over the course from before the flow limit distance of a molten resin to the cavity end. CONSTITUTION:Where the gap of a cavity 3 is t0 and the flow limit distance of a molten resin filled into the cavity from a gate 4 is l0, the gap is gradually enlarged over the course from before the flow limit distance l0 to the end B of the cavity 3 so that the ratio l/t of the distance l between the gate 4 and an arbitrary point to the gap t at the point is roughly equal to l0/t0. When the molten resin forced in from a runner 5 is filled into the cavity 3 through the gate 4, it does not stop flowing at the flow limit point A; instead, it flows as far as the end B of the cavity 3 to thoroughly fill up the cavity 3. After the resin has filled up the cavity 3 and been cooled to solidify, the molded article is released from the mold.
