Title: Charging method for battery of unmanned vehicle
Inventor: HOSOBUCHI EIJI
IPC: H02J7/00
Filed: 1990-03-27
Abstract: PURPOSE:To improve a charging efficiency by running an unmanned vehicle to a charger if the capacity of a battery of the unmanned vehicle is lower than a predetermined value, charging the battery, and charging the battery by a charger when the unmanned vehicle stops if the capacity is the predetermined value or larger. CONSTITUTION:A battery capacity detector 6 provided in an unmanned vehicle 1 always detects the capacity of a battery 2. If it is judged that the capacity is smaller than a reference value, the vehicle 1 carrying the battery 2 is traveled to a working station 3a having a charger 4 at the nearest position by a command from a central controller 5, and the battery is charged by the command from the controller 5 until the capacity of the battery 2 reaches a predetermined value. On the other hand, if the capacity of the battery 2 is the reference value or larger, the vehicle 1 works based on a command from the controller 5, but if it stops at working stations 3a, 3c having the charger 4, it is charged by a command from the controller 5.

Title: Method of partially plating plastics
Inventor: ICHINOSE KOUJI
IPC: C25D5/56
Filed: 1982-05-06
Abstract: PURPOSE:To plate a part only other than a part covered with a covering material, by applying an etching-resistant ultraviolet rays-curing type covering material onto the surface of plastics, curing it, and activating, electrolessly plating and then electroplating an etched surface. CONSTITUTION:The ultraviolet rays-curing type covering material (e.g. unsaturated polyester resin) which is not spoiled by a liquid etchant is applied onto the part of the surface of plastics such as ABS resin from which plating metal will be removed. After said covering material is cured by ultraviolet rays irradiation, the obtd. covered plastics is dipped in a liquid etchant such as chromic anhydride-sulfuric acid, to etch the uncovered part only. Thereafter, the etched surface of the plastics is electrolessly plated and then electroplated, to form a plating layer on the part only other than the part covered with the covering material.

Title: Optical head
Inventor: ISHIBASHI KENZO
IPC: G11B7/09
Filed: 1986-04-02
Abstract: PURPOSE:To detect a good tracking error signal even from an elliptic light spot, by providing a light selecting means which selects spatially a part of reflected light after passing through a diaphragm lens, and an optical detector. CONSTITUTION:A light beam (m) emitted from a semiconductor laser 13 is made incident on a deflection angle prism 4 through a condenser lens 14, and a reflecting mirror 22, and a light beam (m1) is made incident on an optical detector 19 through a deflecting beam splitter 10, etc. In this case, light made incident on the detector 19 become light spots M1' and M2', and through an optical mask 5, the M2' is shielded and only the incident beam of light M1' is made incident actually. In other words, only the reflected light M1' corresponding to the light spot M1 on an optical disk 1 is made incident on the detector 19. In this way, since it is possible to use only the reflected light of the light spot M1 having a strong light intensity, and a small spot diameter on an information track, out of light spot groups forming an elliptic light spot M, for the detection of the tracking error signal, a good tracking error signal can be obtained.

Title: Translucent processing system in smooth shading
Inventor: SUZUKI MASAHIRO
IPC: G06T15/80
Filed: 1987-03-31
Abstract: PURPOSE:To execute a translucent processing based on a complicated Z value interface by holding a Z boundary value corresponding to respective shading object (X, Y) in a Z boundary value buffer. CONSTITUTION:A comparator 6 compares the Z value outputted from a Z boundary value buffer 5 corresponding to the shading object point (X, Y) and the Z value outputted from a shading circuit 1. If the Z value from the shading circuit 1 is smaller than the Z value from the Z boundary value buffer 5, a selection circuit 7 output a luminance value (i) to a signal line (a), and if not, outputs the luminance value (i) to a signal line (b). The luminance value (i) outputted to the signal line (b) passes an OR circuit 11 and is written in an address part corresponding to the shading point (X, Y) which is given from the shading circuit 1 of a frame buffer 8. On the other hand, the luminance value (i) outputted to the signal line (a) is inputted to a gate 10. It is controlled to be opened and closed by a translucent pattern value corresponding to the (X, Y) point stored in a register 9. Thus, the translucent processing can be executed in three dimension.

Abstract: PURPOSE: To provide a low-cost rubber mat having adequate cushion property by mixing refuse tyre fragments with an aqueous emulsion of a specified copolymer and with cement, forming the mixture into the shape of a mat, and curing it.  
     CONSTITUTION: 30 to 70 parts of fragments of under 20mm which have been formed by cutting or craching refuse tyres are mixed with 30 to 15 parts of a 50% aqueous emulsion of a copolymer consisting of 50 to 75% of vinyl acetate, 20 to 10% of ethylene, and 30 to 15% of versatic acid, 30 to 14.9 parts of cement, and 10 to 0.1 parts of cement high-early-strengthening agent. The mixture is extended into the shape of a mat, which cures in 2 to 3 hours. The obtained form exhibits adequately limited rubber elasticity and cushion property suitable for walking on. Because the filmization of the emulsion is effected by consumption of water by the cement, there is produced a rubber mat of stable quality.

Title: Synthetic resin cap
Inventor: HAYASHIDA TERUAKI
IPC: B65D47/06
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To certainly prevent an upper cap from opening inadvertently by increase of pressure in the upper cap by a method wherein an air relief means in which an annular contacting surface is joined with an annular sealing surface is provided at least at one out of an annular holding part of a middle cap and an annular holding part of the upper cap being in engagement with the aforementioned annular sealing surface. SOLUTION: As the temperature of an air A in an interior seal-up chamber 28 rises, the pressure in the chamber 28 increases, and therefore a top plate 21 of an upper cap is pressed and deformed, making an annular projected part separate from a spouting tube 5 to form a gap in between. As a result, the air A passes through the gap and flows into an exterior seal-up chamber 29. As the pressure in the interior seal-up chamber 28 increases further, a side wall 22 is displaced upward, and its engagement protuberance 25 rises, sliding over an annular sealing surface 9a or the like of an engagement indent 9 of a middle cap.  As an annular sealing surface 25a of the engagement protuberance 25 separates from the annular sealing surface 9a of the engagement indent 9, an annular contacting surface 25b comes into contact with the annular sealing surface 9a and at the same time, the exterior seal-up chamber 29 is made to communicate with the outside air through an air relief groove 26.
