Title: Ball-point pen
Inventor: KOBAYASHI SEIICHI
IPC: B43K7/10
Filed: 1994-04-12
Abstract: PURPOSE:To prevent a backflow of ink on the occasion of writing in an upward state or due to shock, and prevent a direct flow thereof at the time when a ball-point pen is put downward, regarding the ball-point pen using shear-rate thinning ink. CONSTITUTION:When a tip 5 is directed upward, a ball valve 15 comes into close contact with a ball seat 14 of a valve chamber 13 and closes up a guide hole 21 and, therefore, ink does not flow backward even when it is exhausted just under a point ball 5a. When the tip 5 is directed downward, accordingly, the ink can be made to flow out immediately and blurring in writing is prevented. Since the point ball 5 is always in close contact with the inner edge of a tip holding part, besides, the blurring in writing due to drying of a fore-end part is prevented. Sucking-in of air due to the writing in an upward state or a shock is prevented by a joint operation of the point ball 5a and the ball valve 15 and, therefore, no blurring in the writing occurs. By providing a winding part of a spring 17 properly in accordance with the shape of the inner hole part of the tip, the flow rate of the ink is regulated and the tendency of a backflow of the ink just under the point ball in the writing in the upward state is moderated.

Title: Game machine
Inventor: SATO ERIKO
IPC: H05F3/02
Filed: 1996-04-18
Abstract: PURPOSE: To improve workability in maintenance, inspection, etc., from the front side of a game machine. CONSTITUTION: The front face of a pachinko machine 10 is usually covered by an upper part front frame 14 and a tray part member 32. When the upper part front frame 14 is opened, approximately the whole play panel 12 and the surroundings are exposed. In addition, when the tray part member 32 is opened, the inside of the pachinko machine 10 on the front face side is almost exposed. Therefore, workability for maintenance, inspection, etc., from the front face side is improved. As even through the upper part front face frame 14 holds a glass frame 13, it does not hold such a heavy part as the play panel, a large force is not required for operation for opening and closing.

Abstract: PURPOSE:To improve an electric charge holding characteristic of a memory cell by suppressing a channel leak current of a memory transistor of a memory cell in a non-selection state, associated with potential variation of a word line and/or a bit line. CONSTITUTION:A level converter 31 converts word line group specifying signals having same amplitude as a power supply potential Vcc and a ground potential GND from a row decoder 20 into logical signals WD and ZWD in which amplitude are high voltage Vpp and a negative potential Vbb and which are complementary each other. A RX decoder 3 outputs a signal having amplitude of Vpp-Vbb specifying one word line out of word line group. A word driver provided corresponding to each word line transmits a word line specifying signal RX or the negative potential Vbb to corresponding word lines WL in accordance with the signal WD and ZWD from the level converting circuit. When a word line is in a non-selection state, the negative potential Vbb is applied to the word line through a MOS transistor N2 or N3. When a word line is in a selection state, the high voltage Vpp is applied to the word line through the MOS transistor N2.

Filed: 1989-04-19
Abstract: PURPOSE:To obtain the microactuator which can adjust a device finely by providing a moving mechanism made of a piezoelectric material, plural electrodes provided on beams, and a control circuit which moves a table. CONSTITUTION:The microactuator is constituted by providing the moving mechanism 10, the electrodes 17 - 20 provided on the beams 12 - 15, and the control circuit 21. When the control circuit 21 applies negative voltages having the same voltage level to the electrodes 17 and 18 and positive voltages to the electrodes 19 and 20, the beams 12 and 13 made of piezoelectric materials contract and the beams 14 and 15 expand. Their quantities of variation correspond to the voltage levels and they operate reversely when the voltages are applied reversely. Consequently, the table 16 is balanced and moves as shown by an arrow (a). Further, when the electrodes 17 and 20 are applied with negative voltages and the electrodes 18 and 19 are applied with positive voltages at the same time, the beams 12 and 15 contract and the beams 13 and 14 extend, so that the table 16 turns as shown by an arrow (b). The table rotates reversely when the voltages are applied reversely. Consequently, the fine table 16 can be moved to a desired position and a system to be adjusted is mounted on the table 16 to enable parallel movement and turning on the table plane, thereby adjusting the system to be adjusted finely.
