Title: Thyristor stack
Inventor: FUJIMOTO TAKAFUMI
IPC: H01L25/11
Filed: 1993-12-24
Abstract: PURPOSE:To prevent the breakdown of a thyristor due to the insufficiency of pressing force of thyristors, by bonding and fixing a resistance strain gauge on the surface of an FRP insulating band, and detecting the quantity of electricity converted by the resistance strain gauge when the FRP insulating band is displaced more than a specific distance. CONSTITUTION:Thyristors 1, heat sinks 2 for cooling the thyristors 1, a block 4 for holding the thyristors connected in series from both sides, and a insulating band made of reinforced plastic (FRP insulating band) 5 for pressing and holding the thyristors 1 and the heat sinks 2 are installed. A resistance strain gauge 6 which converts the displacement of the FRP insulating band 5 into a quantity of electricity is stuck on the surface of the FRP insulating band 5. When the FRP insulating band is displaced more than a specific distance, the converted quantity of electricity is detected by the resistance strain gauge 6. That is, the change of pressing force of the thyristors 1 is caputured as the displacement of the FRP insulating band 5. This displacement can be detected as a voltage, with the resistance strain gauge 6.

IPC: G02B3/08
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To accurately machine an original die for forming Fresnel lenses having an ideal blaze-grating. SOLUTION: The path and the feed quantity of a diamond bit 6 in relation to a blank are controlled so that an edge 6b of the diamond bit 6 is moved toward the center 0 of rotation the blank while it traces a target two dimensional contour line 30. Besides, the target two dimensional contour line is referred to a contour line of the crosssectional shape of an ideal blaze-grating. Since the edge 6b of the diamond bit 6 has roundness having the diameter (3μm or more and 10μm or less) determined by the feed rate, the spherical shape of the edge 6b of the diamond bit 6 is transferred to the surface of the blank as the blank A is rotated.

Title: Dispenser for dispensing liquid or creamlike substance in small drops and dispensing assembly including the same
Inventor: KUROODO JIYUIYA
IPC: B05B11/00
Filed: 1989-12-20
Abstract: PURPOSE: To deliver liquid drops with small volumes by forming a pump chamber equipped with a surrounding body having a bottom wall and an opening at a most distal end from the bottom wall within a pump main body and arranging an exit valve between a central passage of a rod and a delivering orifice of an end tip. CONSTITUTION: When a movable assembly (a rod piston 3 equipped with a check valve) and an end tip 2 are lifted, a volume in a chamber C increases and drawing in the chamber also increases until a piston head part 31 is separated from a bottom wall of a pump chamber C to stop attaching with a surrounding body 11. Then, by returning the movable assembly to a rest position by means of a spring 4, a pressure increases in a volume consisting of the chamber C, a passage 34 and a duct 35. The pressure separates the check valve 5 from an opening 34' and released via a passage 24' of an end tip 2 by the volume of the chamber C. A head part of a piston 31 contacts with a bottom wall of the pump chamber to make the volume of the chamber approximately zero at an end of a stroke.  In the case that an outer diameter L of an orifice 24 of the end tip 2 is sufficiently small, released liquid drops are separated. In order to make priming easy, the volume of the passage 34 is determined to be smaller than the volume of the chamber C and the volume of the chamber C is equalized to a volume of liquid drops to be delivered.

Filed: 1992-12-10
Abstract: PURPOSE:To prevent excess wiring and signal reflection by sending an input signal to a reserve terminal through a 2nd switch group constructed in the tournament system to a reserve transmission/reception section when a fault occurs in an active transmission or reception section. CONSTITUTION:When a fault occurs, for example, in a transmission/reception section 100-1 from among active transmission/reception sections 100-1 to 100-n, an active terminal for a 1st switch group corresponding to the transmission/reception section 100-1 is switched to the reserve terminal. An input signal applied to the reserve terminal is sent to the reserve transmission/ reception section 100-p through a 2:1 switch 500 of a 2nd switch group and a 2:1 switch 500 of the final stage constructed in the tournament system. Thus, excess wiring is eliminated and time release end of the switch 500 is not connected to the reserve transmission/reception section 100-p, resulting in preventing the reflection of signal due to the release end of the 2:1 switch 500.
