Title: Lighting device
Inventor: FUTAMI KAZUMITSU
IPC: H02K15/03
Filed: 2000-03-09
Abstract: PROBLEM TO BE SOLVED: To provide sufficient illumination even with a small pedaling force. SOLUTION: The rotation load of a rotor (not shown in Fig.) is reduced because the amount of magnetization of the magnetic body (not shown in Fig.) of a block dynamo 10 is smaller than usual. A voltage comparison part 44 compares a preset voltage value Vs with the peak value of a half-wave rectified voltage, and when the peak value is less than Vs, a switch 46 is held closed to perform energy compensation control using electric energy. Thus, sufficient illumination can be achieved even with a small pedaling force.

Abstract: PROBLEM TO BE SOLVED: To provide a repair method for optical cables, a method with a short required time. SOLUTION: In repairing a metallic tube 4 for covering an optical cable 1 by means of a resistance welding machine, the shape of the electrodes 10, 11 of the machine is made to coincide with the outer circumferential shape of the metallic tube 4 to be repaired; consequently, the pressurizing force of the electrodes 10, 11 is imparted uniformly in the circumferential direction of the metallic tube 4, enabling brazing to be surely and evenly performed to the end face of a repairing metallic piece 12. The material of the electrodes 10, 11 is such that an electrode with a large electrical resistance is used on the brazing side, so that generation of heat is concentrated therein, heating only the defective part 6 of the metallic tube 4 and enabling efficient welding without wasting energy.  In other words, the metallic piece 12 is fixed, through a filler metal 13, on the defective part of the metallic tube 4 of the optical cable 1, while the metallic tube 4 is fixed on the other electrode 11, and then, after being clamped with one electrode 10, the metallic tube 4 is pressurized and energized; as a result, the filler metal 13 melts at the contact zone between the upper electrode 10 and the metallic piece 12, which is uniformly joined to the metallic tube 4.

Title: Game machine and memory medium
Inventor: KISHI ISAO
IPC: A63F7/02
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a game machine allowing a player to continue a game even when premium balls or rental balls are out. SOLUTION: When a game ball enters winning hole for delivering fifteen premium balls, '1' is stored in a winning ball number memory region 214c corresponding to the address 0FH of the fifteen ball delivery in a winning ball number table 214b stored in a RAM 216. After that, '1' is added to the winning number memory region 214c whenever a game ball enters the winning hole. A sub-CPU installed on a delivery control circuit board drives a premium ball unit to deliver premium balls according to the number of winning balls stored in the winning ball number memory region 214c. Since premium balls can be delivered in this way based on the number of winning balls stored in the winning ball memory region, it is not necessary to store winning balls.  When premium balls and rental balls are out, the drive of the premium ball unit is stopped though the drive of a ball shooting motor is not stopped. Therefore, a game will not be suspended on the way, and a player will not lose interest in the game.

Title: Method of producing quartz glass crucible
Inventor: AKIYASU KAZUHIRO
IPC: C30B15/10
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To prevent inhibiting the quartz glass from forming single crystal, when the crucible is pulled up, by pulling up the crucible so that the bubbles occluded in the quartz crucible may not be broken even under high heat load. SOLUTION: When the starting powder is molten in the mold 1, H2 gas and O2 gas are introduced immediately after the start of arc discharge to remove the graphite component of the electrodes and the impurities in the starting quartz powder whereby the contamination of the crucible products with the graphite and the impurities can be inhibited and the expansion coefficient of the bubbles can be suppressed and the pressure in the bubbles can be reduced. In addition, a helium gas is fed from the mold to the sedimentary layers of the quartz powder formed in the mold 1 thereby replacing the gas in the voids in the sedimentary layers with helium.  Since the bubbles in the opaque layers are made less expandable to inhibit the reduction of the thermal conductivity, the temperature increase in the crucible can be suppressed on use and resultantly, the bubbles in the clear layers can be prevented from bursting.
