Abstract: A printed wiring board includes an insulating resinous substrate having an aperture unit, a first terminal unit and a second terminal unit consisting of a conductor and formed on top of the resinous substrate, and a fuse unit that electrically couples the first terminal unit and the second terminal unit to each other. At least a part of the fuse unit is disposed over the aperture unit, and in addition, is covered by a porous inorganic covering material having insulating properties.

Abstract: A slot machine 10 includes: reels 101-105 each having symbols 501; backlight devices M7 which individually light the symbols 501; a display window 150 which displays the symbols 501; and a motherboard 70 programmed to run a game in which the reels 101-105 are rotated to rearrange the symbols 501, and a prize is awarded according to a combination of the symbols 501. The motherboard 70 (a1) drives and rotating the reels 101-105; (a2) stops the rotation of a predetermined reel; (a3) causes a backlight source M70 of a backlight device M7, which corresponds to a winning-related symbol 501 out of the symbols 501 rearranged, to be in an on-state while causing a backlight source M70 of a backlight device M7 corresponding to a non-winning-related symbol 501 to be in an off-state; and (a4) executes (a3) every time the rotation of at least one of the reels 101-105 is stopped.

Abstract: A four-cycle engine fueled by a mixture of fuel and lubricant and including valve actuation mechanism contained in the path of the fuel flow. A component of the mechanism including a rotating gear having a gear shaft journalled between wall portions of the engine whereat the wall portions define in part the flow path of the fuel. Through holes provided in the walls to direct fuel-lubricant to the shaft ends journalled in the wall portions for lubrication of the said shaft ends.
