Title: Opening delay relay with backup function during momentary interruption of relay drive power supply
Inventor: NORIHISA KAZUHIKO
IPC: H01H47/18
Filed: 1991-06-04
Abstract: PURPOSE:To reduce the number of components of an opening delay relay and to add a backup function for momentary interruption of relay drive power supply. CONSTITUTION:An electric double-layer capacitor 2, 3, 4 is selected using a setting switch 5, 6, 7. While an operating switch 10 is on, the electric double- layer capacitor selected by means of the setting switch is charged by means of a relay drive power supply 9 and a contact output circuit 8 is then closed. While the operating switch 10 is off, the electric double-layer capacitor discharges. While the discharge current is at or above the return voltage of an opening delay relay 1, the contact output circuit 8 of the opening delay relay keeps a closing state. If the relay drive power supply 8 is interrupted momentarily while the contact output circuit 9 is being closed, the electric double-layer capacitor discharges and the contact output circuit 8 keeps a closing state.

Abstract: PURPOSE:To make it possible to condense steam generated in a heat exchanger within a tank by disposing a tank which causes a heat medium in a circulating pipe, and forming a heat medium suction port of the tank at a level which is lower than a discharge port. CONSTITUTION:A heat exchanger 1 is formed by turning a heating pipe 10 through which a heat medium 3 passes vertically in a helical shape, and a circul a ting pipe 4 is connected to both upper and lower ends of the heating pipe 10. A heat medium 3 within the heating pipe 10 which is heated with the exhaust heat of a combustion apparatus 1 is circulated into a floor heating panel which is a space heating apparatus 5 via the circulating pipe 4 by means of a circulation pump 11. The tank 6 which causes the heat medium 3 to stay is disposed in the circulating pipe 4 between the heat exchanger 2 and the space heating apparatus 5, and a pump unit 13 is formed by the circulating pump 11 and the tank 6. Since the suction port 7 of the tank 6 for sucking up the heat medium 3is formed at a level lower than that of a discharge port 8, the heat medium 3 is supplied through a cap 14 of the tank 6. Since the suction port 7 of the tank 6, which sucks up the heat medium 3is formed at a level lower than the discharge port 8, the heat medium 3 stays constantly at a level higher than the suction port 7 and remains within the tank 6, and a steam 12 is condensed by the heat medium 3 within the tank 6.

Title: Actuator
Inventor: YAMAGUCHI ZENTARO
IPC: F16H25/20
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an actuator to simplify structure and ensure safety. SOLUTION: An actuator is formed such that a nut 18 for a feed is forward and backward movably joined in a screwed-in state with a male screw part 16 formed at the outer periphery of a shaft 15 forward and backward rotationally driven by a motor and a moving cylinder 22 moved axially along the outside of the shaft is coupled to a nut 18. The moving cylinder 22 and the nut 18 are intercoupled through a screw coupling part 22a and a plurality of slip-off preventing pins 23 is peripherally and radially inserted in the screw coupling part 22a and the tip part of each slip-off preventing pin 23 is inserted with the screw root of the male screw part 16 of the shaft 15 having a margin.  This constitution, since load distribution of a moving cylinder and a female screw part is widely and uniformly distributed by a screw coupling part, prevents the occurrence of displacement between the moving cylinder and the female screw part, whereby a female screw member coupled to the moving cylinder is prevented from unexpected floating and safety is ensured.

Title: Surface acoustic wave filter
Inventor: HIROTA EIJI
IPC: H01P7/00
Filed: 1993-06-04
Abstract: PURPOSE:To improve the yield of the surface acoustic wave filter by forming a short-circuit pattern along a scribe line for dividing filters formed on a piezoelectric substrate wafer so as to prevent destruction of an electrode finger produced in the manufacture process. CONSTITUTION:Scribe lines 11 used to divide each surface acoustic wave filters 1 are formed on a piezoelectric substrate wafer 2. The lines 11 are made of wiring patterns having a conductivity to form a shortcircuit pattern. Interdigital electrodes 5, 7 forming IDTs 3, 4 are connected to the lines 11. In the surface acoustic wave filter 1, an electric charge caused by pyroelectricity is caused to provide a potential and it is led forcibly to electrode fingers 5b, 7b of the electrodes 5, 7 in the IDTs 5, 7. However, since the electrodes 5, 5 (7, 7) are short-circuited via the lines 11, they are at an equi-potential. Thus, the dipole moment is suppressed in the electrode fingers 5b, 7b and a high potential causing discharge between the electrode fingers 5b, 5b (7b, 7b) is not produced and destruction due to the discharge is not caused.

Filed: 1991-06-06
Abstract: PURPOSE:To slide a movable contact point to a fixed contact point and lower the operation noise by bringing a tilting collision giving surface in a movable core side into collision with a collision receiving surface in a cover side. CONSTITUTION:A tilting collision receiving surface 5a against which a collision giving surface 2a of a block 2 is brought into collision at the time a movable core 1 proceeds to the operation dead center 11 is installed in the back side of an upper wall of a base 6. A resin material having good sliding property is used for these surfaces 2a and 5a. In the resting conditions, being drawn by a recovery spring 3, the movable core 1 is located at the resting point 10. Consequently. the movable contact point 7 and a fixed contact point 4 are in the condition of being parted each other, that is, in open condition as a relay. When the coil 1a is excited and the coil 1a proceeds to the operation dead point 11, the giving surface 2a of the block 2 and the receiving surface 5a of the cover 5 are brought into collision. At that time, since the giving surface 2a and the receiving surface 5a come into collision with each other while they are tilting, the impact of the proceeding core 1 is moderated and the contact points 7, 4 slides well and have a touch.
