Abstract: PURPOSE: To maintain close contact between the valve seat sealing part and an elastic member during valve closing and provide a valve with perfect closing function and function not to exceed the lower combustion limit by installing a magnetic member or a permanent magnet ring in the valve chamber on the upstream or the downstream side of a valve seat, in the proportional control valve for gas combustion apparatus.  
     CONSTITUTION: A proportional control valve is equipped with the valve seat 11 detachably installed in a valve box 10 and the valve 12 which is raised through excitation of a solenoid 13. On the under surface of the flange 26 installed on a valve shaft 24, the elastic member 28 such as rubber plate etc. for close contact with the valve seat sealing part 27 is installed. The magnetic member or a permanent magnet ring 30 whcih attracts the top edge of the valve body and brings it to contact with is put freely in the annular concaved groov 29 formed in a lower valve chamber 16. With such a constitution, as the excitation current which flows in the solenoid 13 increases, the valve body 12 is magnetized and attracts the ring 30, and when the attracting force of the solenoid 13 increases over the saturated attracting force, it overwhelms the pressing force of the elastic member 28 and the attraction force of the valve 12 and the ring 30, and the valve is opened. When the attracting force decreases below the excitation current in valve opening, the valve 12 is attracted to the ring 30, and perfect closing is formed.

Title: Switching mechanism for rotational-linear movement
Inventor: MARUYAMA FUMIYASU
IPC: G11B15/675
Filed: 1982-05-28
Abstract: PURPOSE:To shift a rotational movement to a linear movement in a condition that a sliding member is held in an elastic manner, by bringing the sliding member into a linear movement by dint of tensile forces of two elastic members corresponding to gears engaging each other. CONSTITUTION:Tensile forces F1 and F2 of springs are exerted on a pin 23 of a sliding plate 22. The tensile force F1 is exerted in the direction of an arrow mark B, the tensile force F2 in the direction of an arrow mark A or in a reverse direction to that of the tensile force F1, and F1 is larger than F2. Thus, the sliding plate 22 is brought into a stabilized state in which it is energized in the direction of the arrow mark B. When gears 9 and 10 spin in directions of arrow marks D and E by an angle beta (=90 deg.), tensile forces F5 and F6 are exerted on the pin 23 of the sliding plate 22. The sliding plate 22 moves in the direction of the arrow mark A to a position where the tensile force F5 is balanced with the tensile force F6. Thus, the sliding plate 22 is brought into a stabilized state. The state is a dead point in that, when a force is exerted from the exterior, the sliding plate 22 commits a toggle motion in the direction (the direction of the arrow mark A or B) of the force exerted thereon.

Title: Method and apparatus for applying intermittent voltage to electrode
Inventor: PEETAA HAFUNAA
IPC: G01F1/60
Filed: 1989-04-12
Abstract: PURPOSE: To prevent the effect of noise based on a switch for applying voltage by connecting the potential of an electrode with one or a plurality of terminals during a time interval when no voltage is applied and excluding the terminal part from the electrode. CONSTITUTION: A voltage supply U is connected with an electrode through switch units SU 2, 7 and an electrode 1 is connected with a differential amplifier 5 through a switch unit SU 3. Consequently, when both electrodes 1 are cleaned electrically, a time control section T controls the SU 2, 7 to close contact pieces 2a, 2b, 7a, 7b and a voltage U is fed in order to clean the electrode, while at the same time, contact pieces 3a, 3b of the SU 3 are turned to block position. During normal measuring operation, potential difference is substantially eliminated between the terminal part on the electrode side and the terminal part of SU 2 on the side opposite to the electrode 1 by means of impedance converters 4a, 4b.  Since fluctuation of voltage is substantially eliminated at the terminal part of SU 2, parasitic capacitance of the SU 2 has no effect on the signal being taken out from the electrode 1.
