Title: Choke coil
Inventor: TAKAGI KUSUO
IPC: H01F17/06
Filed: 1989-03-02
Abstract: PURPOSE:To prevent a noise of a wide frequency band from creeping by a method wherein a core composed of two closed magnetic circuits having one part of a magnetic path jointly is installed and windings are wound in opposite directions so as to be faced mutually on the closed magnetic circuits. CONSTITUTION:The winding sets L11, L12 wound in opposite directions so as to be faced mutually on a closed magnetic circuit C1 containing a jointly owned magnetic path C0 constitute a first choke coil Ch1 having a resonance frequency f1. The winding sets L11, L12 and winding sets L21, L22 connected respectively in series and wound in opposite directions so as to be faced mutually on a closed magnetic circuit C2 containing the jointly owned magnetic path C0 constitute a second choke coil Ch2 having a resonance frequency f2 which is higher than the resonance frequency f1 of the winding sets L11, L12. By this constitution, the respective frequencies f1 and f2 of the choke coil Ch1 and the choke coil Ch2 are different; accordingly, the choke coils have a high attenuation characteristic against a noise of a wide frequency band.

Title: Method for dispensing fluid product packaged in container
Inventor: BROWN PAUL E
IPC: B65D33/38
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for dispensing a fluid product, in a package filled with a fluid product and provided with a dispensing valve which seals by itself. SOLUTION: In a method for dispensing a fluid product filled in a container which, when an external pressure is applied to its side-wall, is deformed and increases internal pressure and which, when the external force is released, restores, the container 2 has a dispensing valve 3 in a discharging opening. The dispensing valve 3 comprises a seal means 4 sealing an area around the discharging opening, a valve head 5 having an orifice 6 which is freely opened and closed, and an elastic diaphragm means 7 sealing a space between the valve head 5 and seal means 4 and also being able to shift the valve head 5 between an inward storage-position and an outward acting- position. By increasing the internal pressure of the container 2, the valve head 5 is shifted to the outward acting-position from the inward storage-position.  However, until the valve head 5 is shifted to the outward acting-position, the orifice 6 is kept closed. And by a further increase in the internal pressure of the container 2, the orifice 6 of the valve head 5 put in the outward acting-position is opened to allow the flow of the fluid.

Title: Manufacture of battery
Inventor: EDA NOBUO
IPC: H01M6/22
Filed: 1983-03-23
Abstract: PURPOSE:To enable a liquid-holding member containing gel electrolyte to be manufacture in a short time successively by irradiating microwave on a gelling agent and electrolyte to turn them into a gel or a solid. CONSTITUTION:After the amount of electrolyte to be held by a nonwoven polypropylene fabric used as a base material is set, the amount of PMMA to be applied to the above nonwoven polypropylene fabric is calculated from the set amount and the specific gravity of the electrolyte. After the calculated amount of PMMA is weighed, it is dissolved in a proper amount of tetrahydrofuran or methyl ethyl ketone which is a good solvent for PMMA. After the base material coated with PMMA is put in a heat-resisting glass Petri dish, 45mul of the electrolyte is poured onto the base material and an upper lid is placed over the dish, then this is put in a microwave range having a frequency of 2,450MHz and an output of 600W before being subjected to microwave irradiation. As a result, a gel-like electrolyte is easily obtained since gamma-butyrolactone having a high boiling point is evaporated with difficulty. The thus obtained electrolyte layer 5 is combined with a sealing plate 1, a case 4, a polypropylene gasket 6 and the like, thereby constituting a battery.

Title: Arc starting method in automatic tig welding of stationary pipe
Inventor: ISHIDA YOUICHI
IPC: B23K9/16
Filed: 1979-04-24
Abstract: PURPOSE: To form the stable weld zone free from burn-through by contacting the backing strip of the specific shape to the arbitrary position on the back side of the groove of butted stationary pipes and applying arc welding with the position of the vertex of said contact surface as a start point.  
     CONSTITUTION: In automatic TIG welding of the butt portions of stationary pipes 1a, 1b, a short-length backing strip 2 having the radius of curvature smaller than the inside diameter of the pipes is contacted to the arbitrary position on the back side of the groove and the TIG welding is started by generating an arc from an electrode 4 while spouting shielding gas from a welding torch 2 to the groove part 2a in the vertex position of said contact surface. Since the radius of curvature of the backing strip is smaller than the inside diameter of the pipe, the contact becomes linear and the spacing between the inside surface of the pipes and the groove bottom of the backing strip is maintained constant, and this makes possible the stable arc starting. In addition, the sheilding gas flows along the curved surface of the backing strip and therefore there is no likelihood for causing turbulence and the weld beads free from defects are formed.
