  • Patent number: 6905413
    Abstract: Each of communication controllers sends a count value of a timer corresponding to the lapse of time from a starting point of reproduction during the reproduction of a music to a communication cable. Each of game controllers calculates, while a multi-play mode is executed in an other game apparatus, a reproducing position of the music in the other game apparatus based on the count value sent from the communication controller and transfers a music data from the calculated reproducing position on to a sound source memory upon the receipt of an instruction signal outputted from a confirmation button of an instructing section and representing confirmation of selection of the multi-play mode. While one game player is playing a music game, another game player can participate in this game in the middle of a music number.

  • Patent number: 5843293
    Abstract: The arc-type evaporator of the present invention includes an anode and a cathode for generating arc discharging, a trigger electrode and a gas supply pipe. The trigger electrode is contacted with the cathode to cause a first spark, and thereafter is separated from the cathode to occur the arc discharge between the anode and the cathode. The gas supply pipe is provided independently of the trigger electrode, and supplies the cathode a reactive gas which reacts with a substance forming the cathode to produce a chemical compound. The gas supply pipe includes a gas blow-out port formed in the neighborhood of the side portion or rear side portion of the cathode to face the cathode. The reactive gas is supplied from the gas blow-out port to an area including the front surface of the cathode.
