Patent JP-S608815-A (JP)
Title: Dustproof cover for sunshine collector
Inventor: MORI TAKASHI
IPC: G02B19/00
Filed: 1983-06-29
Abstract: PURPOSE:To prevent dust from sticking to a parabolic reflecting mirror by covering the parabolic reflecting mirror with a dustproof cover which is made of a transparent insulating member and has an external convex surface. CONSTITUTION:The surface of the insulating member is rubbed against wind and charged electrostatically to the positive polarity when planar or concave or to the negative polarity when a convex. Minus charges floating in the air repulse dust charged negatively, so the dust is hard to stick to the convex surface. Consequently, the sticking of the dust to a lens having a planar surface or parabolic reflecting mirror having a concave surface is prevented effectively.

Title: Remote controller
Inventor: ISHIGAMI YOSHIHISA
IPC: H04Q9/06
Filed: 1988-05-13
Abstract: PURPOSE:To prevent erroneous function by connecting a third diode between one of switching terminals of a switch and one of the ends of an exciting coil with opposite polarity from that of a first diode. CONSTITUTION:Current produced through counter electromotive force of the exciting coil L1 in a remote control relay RY1 having longer operating time after polarity inversion of the voltage of an AC power source VAC scarcely passes through a remote control relay RY2 having shorter operating time, and the majority thereof passes through any one of third or fourth diodes D13, D14. Consequently, counter electromotive force is not produced in the exciting coil L2 of the remote control relay RY2 when the switch S1 for the remote control relay RY1 functions, and erroneous conduction of reverse-blocking switching elements SCR1, SCR2 in a remote control switch RS can be prevented.

Abstract: PURPOSE:To enable to supply high-frequency current securely in case of heavy load, by a method wherein recirculating current GTO thyristors are connected in inverse parallel with main switching GTO thyristors which compose a bridge circuit so that a voltage on a commutating capacitor is controlled steadily. CONSTITUTION:Gate turn-off (GTO) thyristors S1-S4 which are used as main switches are connected so as to compose a bridge circuit and current recirculating GTO thyristors D1-D4 are connected in inverse parallel with each of said thyristors S1-S4. A load resonance circuit with Lo and Co is connected to the output terminal of said bridge circuit through an inductance L and a capacitor C for series resonance. When the load is light, the current is controlled by switching of the GTO thyristos S1-S4. When the load is heavy (when the capacitor voltage Vc becomes more than twice of that of the source voltage E), the capacitor voltage Vc is limited within + or -2E by arc ignition control of the recirculating current GTO thyristors D1-D4.

Abstract: PURPOSE:To make the preparation of a scratchable printed matter possible using only a single printing device by coating offset-printed material containing information with an ultraviolet-curable ink using an offset printing technique, then forming a concealing film on the coat using the same technique after curing. CONSTITUTION:Information 10 is printed on paper P using an ordinary offset printing technique, then the entire area where information 10, 10... is printed, is coated with slightly tinted clear ink using the same technique. The clear ink is curable by ultraviolet ray and the vehicle is composed of prepolymer, monomer and sensitizer. In addition, 3 to 8wt.% of slip agent consisting of silicon resin fat is added, and a coated layer 20 is irradiated with ultraviolet ray for curing immediately after printing the layer 20. If the coated layer 20 has become cured completely, a concealing film 22 is likewise printed using the offset printing technique so that the contents of the information 10, 10... become invisible. Thus, all the scratchable printed matter can be printed using the offset printing technique and also the mass printing can be carried out at a low cost.
