Abstract: PURPOSE: To speedily move a pointer to optional coordinates on a screen by constituting an operation part so that it can slide and move on a plane in all directions and in parallel and also return to an origin. CONSTITUTION: When a resin-molded button 1 is moved with a finger, etc., a 1st magnet 3 while mutually attracting a 2nd magnet 6 is restricted by a sphere 4 at a certain distance, and also slides and moves in parallel on the sphere 4 as a roll. Consequently, the magnetic force balance between the 1st magnet 3 and 2nd magnet 6 is lost and the balance of magnetic fields among detecting elements 4 provided at four peripheral positions of the 2nd magnet 6 is also lost; and respective electric output balances are lost and in which direction and how much the magnet moves are detected in the form of signals. When the finger is put away from the resin-molded button 1, the 1st permanent magnet 3 and 2nd permanent magnet 6 try to keep the magnetic force balance and attract each other to return to the origins.  Thus, the simple constitution wherein the sphere 4 is interposed between the 1st permanent magnet 3 and 2nd permanent magnet 6 makes possible the parallel slide movement and the origin return.

IPC: H01L21/56
Filed: 1991-11-25
Abstract: PURPOSE:To obtain a semiconductor device having a structure wherein air bubbles are not generated in adhesive agent, by a method wherein, when a semiconductor chip is bonded to a bed with pressure, air bubbles generated in sandwiched adhesive agent are made to escape to the rear through a plurality of holes formed in the bed. CONSTITUTION:When a semiconductor chip 10 is mounted on a bed 12, said chip 10 is bonded with pressure by using mount paste 11. Air bubbles generated in the mount paste 11 are pushed out on the rear side of the bed 12, through- holes 16 of the bed 12, by the pressure of bonding. Hence the air bubbles do not remain in the mount paste 11 after bonding with pressure, so that cracks due to the air bubbles in the mount paste are not generated in a package 15 or the semiconductor chip 10 when heat is applied at the time of mounting by soldering or the like. Thus a semiconductor device having a structure wherein air bubbles are not generated in the adhesive agent at the time of fixing the chip on the bed by using the adhesive agent can be realized.

Abstract: PURPOSE: To provide a game machine with which a progress of a game can be grasped at a glance, and with which a game that is highly interesting but simple can be enjoyed by elevating a target game board incorporating a hit sensor while changing the widthwise direction thereof, by retarding the elevation thereof when a ball dropping a stable position strikes upon a target. CONSTITUTION: When a game is started, targets 6a to 6c incorporating hit sensors therein ascend while change their widthwise positions along their game boards 3a to 3c. At an upper stand-by position, manipulating buttons 10a to 10c are depressed with suitable timings while balls 7 are rotated by guide plates 9a to 9c so as to drop balls 7. When the balls 7 strike upon the targets 6a to 6c, the incorporated hit sensors detect hitting of the balls 7 upon the targets 6a to 6c so as to deliver hit signals. Accordingly, a control device which receives the hit signals from the sensors retards the ascent of the targets 6a to 6c. Whether the game is in success or not depends upon whether the targets 6a to 6c come to a predetermined position or not.
