Filed: 2002-11-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an accelerator pedal operating device for a motor-driven vehicle which is constituted so that, when the relation of an accelerator opening degree and a motor output relative to the changes in the motor temperature, a triver is informed of this in an intuitive manner through changes in the reaction force of the accelerator pedal.  <P>SOLUTION: The accelerator opening degree signal of an accelerator opening degree sensor 12 and the temperature detection signal of a motor temperature sensor 14 are inputted in a controller 15. The relation between an accelerator opening degree and a motor output, relative to a motor temperature, is detected.

Abstract: <P>PROBLEM TO BE SOLVED: To provide a game machine which is allowed to keep novelty in a game rendition by using a liquid crystal display panel arranged in front of a variable display means for variably displaying picture patterns as a new equipment configuration element for performing the game rendition.  <P>SOLUTION: The game rendition is displayed in each liquid crystal panel 39d which is arranged in a reel display window part 39 during the game of a slot machine. The liquid crystal panel 39d functions as the new equipment configuration element for performing the game rendition. Thus, the new game rendition is enabled by the liquid crystal panel 39d, so that novelty is easily kept in the game rendition. Since peripheral edge corner parts at the side of the rear surfaces of the opening parts 5c, 6c, 7c are scraped, a player does not visually recognize the peripheral edge corner parts when viewing reels 2-4 behind the liquid crystal panel 39d through a transparent acrylic board 39a. Consequently, the player becomes unconscious of the thickness of a rear holder 39h and the thickness of the whole reel display window part 39.  <P>COPYRIGHT: (C)2004,JPO
