  • Patent number: 6866582
    Abstract: In a slot machine, when a player actuates a start lever, three reels spin, thereby effecting internal drawing operation and determining a winning combination. When the player actuates stop buttons, predetermined stop control operations are performed. A combination of symbols corresponding to the winning combination are achieved along anyone of winning lines. A plurality of image data sets which can be displayed on a liquid-crystal display (21) are recorded in an image data ROM (44) provided in a liquid-crystal display unit (20) of the slot machine. When the player actuates a changeover switch (23), switch setting information is sent to a CPU (41). An image display LSI (45) reads out from the image data ROM image data corresponding to the setting information, thereby using the thus-read image data for display contents of the liquid-crystal display.

  • Patent number: 5601450
    Abstract: A bolt provided on a female connector housing is tightened relative to a nut, provided on a male connector housing, displacing the two connector housings relative to each other in a connecting direction, thereby fitting them together. An upwardly-extending, bar-like projection portion is provided on the male connector housing. A detection member is provided in an insertion hole formed in the female connector housing. When the two connector housings are displaced relative to each other in the connecting direction, the projection pin and the detection member cooperate to indicate a fitting-completed condition, enabling easily perceived completion of the connection. Alternatively, the male and female connector housings include electrically engageable sensing elements that indicate the fitting-completed condition.

  • Patent number: 5501609
    Abstract: This invention aims to provide a connector in which a stationary connector housing is provided on its flange with a cushion member to be closely attached to a panel to give a stable seal function regardless of a change of thickness of the panel. A male connector housing 13 of the connector is provided on an upper periphery on a hood 13b with a flange 13d. The male connector housing 13 is provided with securing fixtures 19 made of a leaf spring material. The housing 13 is secured to a periphery around an opening 12a in a panel 12 by clamping it between an upper elastic piece 19a and a flange 13d. The flange 13d is provided on its upper face with a cushion member 20 which is softer than a seal member 16 of a waterproofing cover 17. When a female connector housing 14 is fitted to the male connector housing 13, the seal member 16 closely contacts with a surface of the panel.

  • Patent number: 5482476
    Abstract: An electrical connector attached to a door or body panel of an automobile for wiring electrical parts includes a body having a front opening and holding, in it, terminals capable of fitting with counterpart terminals, respectively. A pair of locking arms each capable of flexing inwardly are provided at the outer periphery of the body. Each locking arm has a concave-convex engagement structure engaged with an edge of the panel defining a mounting hole when the connector is inserted into the mounting hole. A pair of deformation preventing portions are formed to the inside of the locking arms to be engaged with the locking arms, respectively. The deformation preventing portions prevent deformation of the locking arms by engaging the locking arms, respectively. The locking arms engage the respective deformation preventing portions when something strikes against the locking arms and the locking arms are flexed inwardly.

  • Patent number: 5480312
    Abstract: A protecting cap is used for protecting a plurality of terminals disposed in a cylindrical portion of an electrical connector to be inserted in a mounting hole formed in a panel so that an open end of the cylindrical portion faces the mounting hole. The protecting cap is attached to the open end of the cylindrical portion. The protecting cap includes a lid portion covering the open end of the cylindrical portion of the connector and a pair of engagement members attaching the lid portion to the cylindrical portion of the connector. The lid portion has inclined faces so that the lid portion tapers in a direction away from the open end of the cylindrical portion. Since the protecting cap is tapered, it can be readily inserted into the mounting hole. Upon insertion of the distal end of the cap into the mounting hole, the connector can be guided to a normal position even when it is positionally offset relative to the mounting hole.
