Title: Electromagnetic pump
Inventor: KURAKAWA HISAO
IPC: F04B17/04
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To reduce noise by improving the structure of an electromagnetic pump. SOLUTION: A piston 20 abuts against an electromagnetic plunger 16 accommodated in a guide pipe 9 which is fixed in an electromagnetic coil 2, coaxial therewith, by springs 9, 21 through the intermediary of a cushioning material 5, and is reciprocatably supported. Accordingly, noise upon a bump between the electromagnetic plunger 16 and the piston 20 is eliminated while fluid blocks from flowing into through a gap between the electromagnetic plunger 16 and the piston 20 in order to stabilize the motion of a discharge valve 31, thereby making it possible to restrain occurrence of abnormal sound.  The diameter of an intake valve 30 provided upstream of the piston 20 is larger than that of the discharge valve 31 provided downstream thereof, and accordingly, the diameter of a seat part 13a onto which a valve element 30b of the intake valve 30 is seated, is larger than that of a seat part onto which a valve element 31b of the discharge valve 31 is seated. Accordingly, the suction efficiency of fluid can be enhanced so as to reduce the degree of lift of the valve element 30b of the intake valve 30, thereby making it possible to reduce noise produced by the valve.

Title: Voltage amplifier
Inventor: MOLDSVOR OEYSTEIN
IPC: H03M1/44
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a technique of linearization for an analog/digital converter for improving a sprious-free dynamic range or full higher harmonic distortion by providing a control means for determining the connection of a switching capacitor and a pseudo binary random number generator for controlling the control means. SOLUTION: A switching capacitor type amplifier having a gain equal to '2' is operated in two phases. In the first phase (sampling phase), a switch Φ1 is closed and an input signal is connected to capacitors CF and CS. While using the state of a digital signal DS generated by the pseudo binary random number generator, the control means determines which of capacitors CS and CF is to be used as a feedback capacitor for each clock cycle. In the second phase (amplifying phase), a switch Φ2 is closed. For example, all the charges stored in the capacitor CS are transferred to the capacitor CF and a gain (CS+ CF)/CF is obtained.

Title: Vulcanizer of tire
Inventor: KINO NATSUSHIRO
IPC: B29C33/02
Filed: 1993-10-29
Abstract: PURPOSE:To miniaturize structure for elevation of a mold and make elevation distance long, by a method wherein a crank fulcrum performing circular motion and a point of action of a top slide are connected by a second link and first link with each other through a lever. CONSTITUTION:A crank gear 11 performs circular motion reciprocating between a point A on this side of an upper dead center and a point B on this side of a lower dead center by a pinion gear 12. A crank stroke H1 of the crank gear 11 is amplified by a lever action by a lever 16. By setting appropriately a lever ratio, a vertical elevation distance H2 necessary for taking out of a vulcanization-molded tire or fitting of a green tire can be secured between a top and bottom molds 4, 5. Although a crank mechanism which is a mechanical type and has simple structure is used, it can be made into an inexpensive and highly-accurate vertical type tire vulcanizing machine without enlarging the crank gear 11 more than it is necessary, and the structure can be made simple.

Title: Placing apparatus of rocking vibration table type
Inventor: MURATA HIKARI
IPC: B28B1/087
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently use the vibrating energy of a vibrator as the placing energy of concrete by providing a table rockably mounted at an indicating member, and directing a pair of eccentric weights oppositely to the loading direction. SOLUTION: Vibration motors 5a, 5b are installed at both ends of a table 2. Eccentric weights 6a, 6b are respectively assembled with the motors 5a, 5b and rotated by the motors. The weights 6a, 6b are deviated at the positions of the centers of gravities at 180 deg. to be rotated around the rotary shaft. Thus, when the weight 6a side is disposed at the highest position, the weight 6b becomes the lowest position. Since the displacement by the vibration of the motor 5a becomes reverse in phase to that of the vibration of the motor 5b, the right and left ends of the table 2 are alternately lifted and vibrated in a seesaw manner around a fulcrum 4.

Title: Antenna direction setter
Inventor: ISOBE SEIJI
IPC: H01Q3/00
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To direct an antenna correctly toward the incoming direction of signal by extracting the horizontally and vertically polarized components of a receiving signal while separating from each other and then mixing the extracted signal components thereby detecting the incoming direction of signal surely. SOLUTION: A broadcast signal received by an antenna 11 is separated through a separator 12 into horizontally and vertically polarized components H, V which are then mixed through a mixer 17. The horizontally and vertically polarized components H, V have been modulated by an identical signal and have an identical frequency. The horizontally and vertically polarized components H, V are mixed through the mixer 17 to produce a DC component. The DC component is passed through a low-pass filter 20 in order to remove noise component and then applied to a level detector 21 in order to detect the level of signal component. When the antenna 11 is directed correctly toward the incoming direction of signal, signal component of vertically polarized signal V goes zero and the signal component is reduced.  Consequently, when the antenna 11 is set in the direction of reduced signal component, it is matched with the incoming direction of signal.
