  • Publication number: 20220323967
    Abstract: An electric pulse decomposition method for separating a composite material by an electric pulse, the composite material being obtained by bonding or joining a plurality of conductors to each other with an insulating member, the electric pulse decomposition method including a protrusion formation step for forming a protrusion in a specific site, on a side on which the composite material is arranged, of at least one of the plurality of conductors, and a separation step for separating the plurality of conductors in the composite material 1 by respectively bringing electrodes into contact with surfaces of the plurality of conductors and applying an electric pulse between the electrodes to destroy the insulating member. This makes it possible to separate the plurality of conductors from the composite material by making a shock wave caused by a current of the dielectric breakdown functioning as an adhesive to effectively destroy the insulating member.

  • Patent number: 8123601
    Abstract: To provide a game device capable of realizing a user interface that makes it easier for a player to realize a reference trajectory to input and a time to begin inputting of the reference trajectory. A display unit (74) displays a game screen including a moving image and a trajectory image for indicating a reference trajectory. The moving image moves from a given initial position to the start point of the reference trajectory. In the case where the moving image reaches the start point of the reference trajectory, the moving image moves along the reference trajectory. A determination unit (78) determines whether or not the position designated by a player is located within an area based on the position of the moving image during a period when the moving image is moving along the reference trajectory. A game process is carried out based on a result of determination.

  • Patent number: 6469242
    Abstract: In a substrate-integration-type thin-film solar cell module wherein an element is directly formed on a transparent insulating substrate, wiring between a bus region and a terminal box is formed of a solder-plated copper foil. To ensure insulation between a device surface and the solder-plated copper foil, an insulating sheet buried in a filler is inserted in a gap therebetween. A glass nonwoven fabric sheet or a 160° C.-heat-resistant synthetic fiber fabric sheet can be used for the insulating sheet. Contact between an edge of an opening in a back protection cover and the wiring is prevented by positioning output wiring by means of an insulating sheet portion. An insulating sheet for preventing entrance of water from the opening is disposed at the opening.
