Title: Bit line sensing circuit of semiconductor memory device
Inventor: CHIYOU MASAATSU
IPC: G11C11/409
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain the bit line sense circuit which can be placed in high-speed stable sensing operation by enabling both power source noise suppression and high-speed operation. SOLUTION: The bit line sensing circuit consists of an N type sense amplifier for preoperation and a P type sense amplifier for postoperation which are provided between a couple of bits, and is made to operate by applying a pull- down voltage to the N type sense amplifier and a pull-up voltage LA to the P type sense amplifier. The pull-up voltage LA is applied to a transistor(TR) 121 under control with a pull-up control signal LAPG, but if the pull-up control signal LAPG has steep active transition, the peak current is large to possibly cause noise generation, but when the transition is gentle, a sense time becomes long. Therefore, the signal LAPG is given the gentle transition until bit line potential expansion advances to some extent and the steep transition thereafter.  For the purpose, a pull-up control signal generating circuit is provided with a PMOS transistor 516 and an NMOS transistor 515.

Title: Video game machine
Inventor: NAKAKUKI SEIICHI
Filed: 1994-12-13
Abstract: PURPOSE: To make the prediction of a locus difficult in a video game machine and enhance the feeling of satisfaction regarding a game by applying the constitution that a piece shot in a slantwise direction rebounds, upon collision with a wall. CONSTITUTION: When a ball 22 is shot from a turret 20, the preset displacement is added to the current position of the ball 22 for the travel thereof. For example, the preset displacement is added to the Y-coordinate of the ball 22, and the preset displacement is deducted from the X-coordinate thereof, thereby displaying the ball 22 as if moving in a left upward direction. Then, judgement is made as to whether the collision of the ball 22 relates to a right wall or a left wall 23 for performing the required rebound process. In the case of collision with the left wall 23, for example, the rebound process is performed by adding displacement along the X-axis. In the case of collision with the right wall, displacement is reversed in a direction for deduction. As a result, a player can see the ball 22 as if rebounded from the wall 23.
