Patent JP-H04304016-A (JP)
Title: Output buffer circuit
Inventor: HATTA TOSHIYA
IPC: H03K17/16
Filed: 1991-04-01
Abstract: PURPOSE:To reduce the production of noise by controlling the gate potential of a P-channel transistor(TR) and the N-channel TR of a CMOS inverter configuration being a main buffer circuit driving an output terminal. CONSTITUTION:When a signal at an input terminal transits from L to H, the outputs of CMOS inverters G1, G2 transit from H to L and the output of a CMOS inverter G3 transits from L to H. Till the output of the inverter G3 goes to the high threshold level of a CMOS inverter G4, since a CMOS inverter C6 outputs an L level, a P-channel TR P4 is turned on and an N-channel TR N4 is turned off and the output of the inverter G1 gets higher than a ground potential by the potential of the TR P4. Thus, a TRP3 ON-current is reduced, a potential transition at an output terminal 2 is slower and the peak level of a supply current from the power supply is reduced. Similarly, even when a level at the input terminal 1 transits from H to L, the transition of the potential at the output terminal is slow. Thus, noise is reduced.

Title: Dye cell
Inventor: SATO TOSHIO
IPC: H01S3/213
Filed: 1987-03-23
Abstract: PURPOSE:To obtain dye laser having Gauss distribution or light intensity distribution similar to the Gauss distribution, by forming scattering surface on the excitation laser-light transmitting surface of a dye cell. CONSTITUTION:Exciting laser light W is condensed through a cylindrical lens 12 with respect to the forming direction of a dye flow path 11, i.e., the flowing direction S of a dye solution. The light is projected on a ground-glass state scattering surface 13 of a coloring matter cell 10. Since the light W is scattered when the light is transmitted through the surface 13, the intensity distribution of the light W in the flow path 11 becomes uniform. Therefore, even if the lateral modes of the light W are multiple and the intensity distribution has a doughnut shape, the effect of the light intensity distribution is not imparted. The intensity distribution of the excitation laser light W becomes uniform in the flow path. As a result, oscillating dye laser light Qa has Gauss distribution or distribution similar to the Gauss distribution.

Title: Liquid pressure controlling device for dual piping system
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/26
Filed: 1981-05-07
Abstract: PURPOSE:To eliminate the overshooting of liquid pressure in spite of the generation of pressure difference by a structure wherein a valve in a balancing system, which actuates in cooperation with a main system, consists of a ball and a spring, the force of which is designed to be cpmparatively strong and to be released just before the seating of the ball onto a valve seat. CONSTITUTION:The liquid pressure in the main system a is proportionally controlled by means of a controlling piston 17 and a controlling spring 19, while the liquid pressure in the valancing system b is controlled so as to be equal to the liquid pressure in the main system a by means of a balancing piston 13 and the valve (a valve seat 23 and a ball 25). The valve of the balancing system b consists of the ball 25, the valve seat 23 and the energizing spring 24, the force of which is released just before the seating of the valve ball 25 onto the valve seat 23. Owing to the structure as mentioned above, the stroke necessary for the equilibrium of the liquid pressure of the main system and of the balancing system becomes extremely small, resulting in eliminating the overshooting of liquid pressure.

Filed: 1982-04-26
Abstract: PURPOSE:To simplify the control and lower the cost, by arranging rotatably a rotor between fixed plates having passages, the rotor being for changing over the passages and for shutting off the passages.
