Title: Welding method for preventing ignition and equipment therefor
Inventor: OGOSHI YOSHIHIRO
IPC: B23K11/11
Filed: 1987-03-03
Abstract: PURPOSE:To prevent an adhesive applied to weld zones from igniting by setting the blowoff time of air blown off toward the vicinity of the weld zones of base metal according a welding condition. CONSTITUTION:At the time of welding in order the weld zones A, B, C... of the base metal 30, the welding condition is set by a welding condition setting part 15 of a control panel 14 and the direction of an opening end 11' of an air nozzle 11 is set to the prescribed direction. A welding robot 1 is driven to position a welding gun 10 on the first weld zone A which is held between both electrodes 25 and 26. At the time of welding the welding zones A, B, C... in order with the sequential control in this state, a signal is outputted from the welding condition setting part 15 to an air valve 16 at the time of welding or just before the welding to open the air valve 16 and the air is blown off from the air nozzle 11. By this method, the adhesive for the temporary adhesion at the welding zones can be prevented from igniting and since a large- sized fan, etc., are not used, energy saving can be realized.

Title: Adjusting for air gap in linear motor device
Inventor: NAKAI KEIICHIRO
IPC: B66B9/02
Filed: 1989-02-28
Abstract: PURPOSE: To reduce travelling noise and at the same time surely ensure the minimum air gap by detachably mounting an elastic body having a contact part in the state of slidable contact on the opposed surface of the moving element of a stator in a linear motor device and maintaining an air gap to be not less than a predetermined gap. CONSTITUTION: An elastic body unit 15 surrounds the whole circumference of a column 10, and a wiping member 15c is always elastically brought into slidable contact with the surface of a column. The elastic body 15 is used for merely giving elastic force for maintaining contact with the wiping member and the surface of the column 10, and the contact resistance of the wiping member and the column, namely, the travelling resistance at the time of the travelling of a counter weight unit is very small. The elastic body 15 ensures a predetermined minimum air gap by restricting the relative displacement of the a coil unit 1. Therefore, the holding of a predetermined air gap between the column and the coil is ensured, thereby being able to minimize the generation of travelling noise.

Inventor: KUWABARA AKIYASU
IPC: F02M25/07
Filed: 1978-04-28
Abstract: PURPOSE: To reduce production of NO x  by feeding back the adquet amount of exhaust gas to an intake pipe according to the amount of air through an exhaust gas feedback valve which is provided in the intake pipe in a diesel engine coinciding with a regulation valve which opens or closes according to the opening of a throttle valve.  
     CONSTITUTION: A regulation valve 3 is provided in an intake pipe 1, using a lever 5 and rod 4 to coincide with a throttle valve not illustrated. An exhaust gas feedback valve 8 moves with the regulation valve 3, which opens or closes an exhaust gas feedback outlet port 6. Exhaust gas whose amount varies from opening of the throttle valve is fed back into the intake pipe 1 from an exhaust gas recirculation passage 7 laid on the outside of the intake pipe 1. Both currents upstream and down stream the regulation valve 3 are communicated by a bypass 9 aside the intake pipe 1. An electromagnetic valve 10 is provided above the passage 9, which makes the bypass 9 through only when an engine is cold.

Title: Light quantity controller
Inventor: SAKAKIBARA KENJI
IPC: G05D25/00
Filed: 1986-03-06
Abstract: PURPOSE:To attain the control of light quantity with satisfactory responsiveness even to a large quantity of light in a simple constitution, by controlling the temperature of a shield plate made of a shape memory alloy and set on an optical path to control the light quantity. CONSTITUTION:A light quantity control array 10 contains a light pass hole 12 at its center part and many light shield plates 14 made of a shape memory alloy are arranged regularly at the hole 12. The surface of the plate 14 is partially expanded for formation of a shield part 15 and therefore the incident light given from a light source 40 is cut off by the part 15 when no current flows to each plate 14. Thus the light does not reach a light entering part 50a of a Selfoc lens 50. Then the temperature of the plate 14 rises up in proportion to the internal resistance of the plate 14 when the current flows to each plate 14. Thus the plate 14 is displaced so that the surface of the plate itself is set in the direction vertical to the light traveling direction. Then the light of the source 40 reaches a photosensitive drum 60 through the lens 50.

Abstract: PURPOSE:To stabilize the vibration energy of a vibrator and to efficiently transmit the energy to an ink for the facilitation of a stable high speed printing operation, by supporting the vertically vibrating horn of a head at the node portion of the vibration, and providing an efflux line of the ink inside the horn. CONSTITUTION:A horn 1 is provided at its bottom part 2 with an electromagnetostrictive vibrator 3 for generating a supersonic vibration, and at its top part 6 with a nozzle plate 11 having a small opening 10. A part 4, which acts as a vibration node when the horn 1 vibrates, is supported by the bottom part 13 of an ink chamber 12. Inside the horn 1 is arranged an efflux line 9 of the ink comprising holes 5, 8. An ink is supplied through an ink feed pipe 15 to the efflux line 9 of the ink. When the electromagnetostrictive vibrator 3 is vibrated supersonically, the amplitude of the vibration is amplified and transmitted to flow out the ink through the small opening 10 from the efflux line 9. Consequently, the ink in the ink chamber 12 is ejected through a spout 17 at the front side 16. In the ink chamber 12 the ink whirls around the top part 6, so that an ink free from solid inclusions is constantly present near the spout 17.

Title: Method for analyzing chlorine in silane
Inventor: TAKAHASHI YASUHIRO
IPC: G01N30/88
Filed: 1993-03-11
Abstract: PURPOSE:To analyze impurities containing chlorine in a silane safely, simply and highly accurately by bringing the to-be-inspected silane in touch with water and detecting chlorine from the water in touch with the silane with the use of ion chromatography. CONSTITUTION:A to-be-inspected silane is brought in touch with water, and chlorine impurities are dissolved in water as chlorine ions. This water (absorbed water) is analyzed with the use of ion chromatography, whereby chlorine in the silane gas which would spontaneously ignite in the air is analyzed safely, easily and highly accurately. For example, the silane gas is introduced into an absorption container containing a predetermined volume of water and passed through the water to bubble. The silane gas passed through the water is guided outside the absorption container via a different conduit, transferred and processed in a harm-removing device. In order to analyze the concentration of chlorine ions in the absorbed water, chlorine ions are separated by a column in which an anion exchange resin is filled and quantified according to the ion chromatography.
