Filed: 2000-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a path setting device and method with which number of labels in use can be decreased to enhance the transfer capability, in a label switching network employing a distance vector type routing protocol. SOLUTION: Upon the receipt of a label request with respect to a new flow, a same path discrimination processing section 28 of a label management section 23 retrieves a label switched path(LSP), having already been set and compares the path with a path included in the label request. When an LSP of the same path as that in the label request exists, the label management section 23 assigns the same label to the label request, and when the LSP as above is not in existence, the label management section 23 assigns a new label to the label request. A switch-setting section 22 sets the LSP, based on the label assigned by the label management section 23.

Title: Stage device equipped with overrun sensor
Inventor: SUZUKI SHIGERU
IPC: H01L21/027
Filed: 2000-05-09
Abstract: PROBLEM TO BE SOLVED: To enable a stage device which moves a stage in X-, Y-, and θdirections by means of three driving elements to secure the normal movement of the stage by independently detecting the overrun of the stage in the X-, Y-, and θ directions. SOLUTION: When the stage 20 is moved in the X- and Y-directions, a dog 1 in the X direction approaches an X-direction sensor 2b or a dog in the Y direction approaches a Y-direction sensor 4b. When the moving amount of the stage 20 in the X- and Y-directions exceeds a limit value, the X-direction sensor 2b or Y-direction sensor 4b stops the stage 20 for preventing the overrun of the stage 20 by generating an output. When the stage 20 rotates (in the θdirection), only one of two push rods 5 and 6 is pushed and moves in the +X-direction and the other rod moves in the -X-direction. Consequently, a dog bar 7 and a sensor bar 8 rotate in the opposite directions. When the rotational amount of the stage 20 exceeds the limit value, a θsensor 8b stops the movement of the stage 20 for preventing the overrun of the stage 20 by generating an output.

Abstract: PROBLEM TO BE SOLVED: To achieve a discharge of balls to be dispensed in a proper form reflecting the ball dispensing operation by simplifying the control at a discharge control means in a game machine in which a discharge mechanism for discharging game balls as prize balls or balls to be dispensed is controlled by a discharge control means. SOLUTION: In the discharge of prize balls, the demanded number of prize balls to be discharged from a game controller 100 are cumulatively stored into a storage counter and a discharge unit 600 is made to perform discharging operation corresponding to a value of a discharge counter set based on the residual number of the storage counter. The number of balls discharged detected by a prize ball detection sensor 713 is directly subtracted from the storage counter while when a dispensing ball discharge command is given, the unit number of balls to be dispensed from a card unit 500 is set on a discharge counter being given preference to the residual number of the storage counter.  At the same time, the number of discharged balls detected by a dispensed ball detection sensor 714 is subtracted from the discharge counter and while the residual number is left in the discharge counter, balls left are discharged corresponding to the residual number.

Title: Fuel cell apparatus
Inventor: SANO SEIJI
IPC: H01M8/24
Filed: 2000-05-11
Abstract: PROBLEM TO BE SOLVED: To provide an operation of a fuel cell in a good condition by improving a condition of water in the fuel cell. SOLUTION: The condition of water content inside a fuel cell stack 30 is determined based on an exhaust gas flow from flow meters 72, 82, an exhaust gas pressure from pressure gauges 74, 84, an exhaust gas temperature from thermometers 76, 86, and an output current from an ammeter 56. A compressive stress mechanism 40 is driven so that a compressive stress for the fuel cell stack 30 is reduced when a flooding condition is judged from the condition of the water content and increased when a dry-up condition is judged from the condition of the water content. Compressive stress adjustment leads to an adjustment of water movement space inside the fuel cell stack 30, thus providing a proper condition of the water content inside the fuel cell stack 30. This allows the operation of the fuel cell stack 30 in a good condition.
