Title: Large sized three-piece solid golf ball
Inventor: NAKAHARA AKIHIRO
IPC: A63B37/00
Filed: 1989-03-01
Abstract: PURPOSE:To enable a three-piece golf ball to possess a higher repellence than the conventional two-piece golf ball and to improve the impulse force at striking by making a difference between the central hardness of a ball's inner core and the hardness of covering to the extent of 10 or more, and satisfying the equation involving the specific gravity of inner core and the specific gravity of covering; 1.0< the specific gravity of inner core <= the specific gravity of covering <1.3. CONSTITUTION:A three-piece solid golf ball is such that the diameter of inner core 1 is 29-36mm, the diameter of solid core is 37-41mm, the central hardness of inner core is 25-70, the hardness of covering is 80-95, the difference between the central hardness of inner core and the hardness of covering 2 is 10 or more, and the equation is satisfied involving the specific gravity of inner core and the specific gravity of covering; 1.0< the specific gravity of inner core <= the specific gravity of covering <1.3. The compound ingredients of solid core include base material rubber, cross linking agent, co-cross linking agent and inert filler. It is desirable that the inner core be much softer thant the covering. If the difference is 10 or less, the repellence is lowered and the impulse force at striking is increased.

Title: Dc power supply circuit
Inventor: KAKIMOTO KOJI
IPC: G05F1/56
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a DC power supply circuit with which a rush current is limited by taking the start delay time of DC/DC converter when a power source is turned on again even just after the instantaneous reduction or hit of input voltage. SOLUTION: A delay reset circuit 1 is provided between a DC supply power source 2 and a delay start-up circuit 5. The delay start-up circuit 5 limits the rush current by taking the start delay time of DC/DC converter 3 on the next stage corresponding to the charging time of capacitor Cset. Because of hit at the DC supply power source 2, a transistor Qs for delay reset is changed from OFF to ON based on the time constants of resistor Rb and capacitor Cb. Since the transistor Qs for delay reset is turned on by the charging voltage of capacitor Cset, the capacitor Cset is discharged by turning on the transistor Qs for delay reset. Therefore, since the capacitor Cset can keep the charging time, even when the hit frequently occurs, the rush current at the time of turning on the power source can be limited and reliability in practical use can be secured.

IPC: G06F1/14
Filed: 1979-04-24
Abstract: PURPOSE: To make use of a program counter as a timer with efficiency by actuating the program counter as a timer and then by restoring the contents of a stand-by register in the program counter while removing a prohibition of instruction inputting to an instruction register when the count value of the program counter reaches a fixed value.

When the count value of counter 3 reaches a fixed value, the prohibition of instruction inputting to gate 8 is removed and the stand-by contents of register 9 are restored in counter 3. Consequently, counter 3 can efficiently be used as a timer.
