Title: Magnetic switch
Inventor: FUJIWARA ETSUO
IPC: H01S3/097
Filed: 1990-11-29
Abstract: PURPOSE:To ensure the prolonged life of the title switch by providing on a central axis a plurality of ring-shaped ferrites or amorphous metal magnetic materials to increase the inductance immediately after the onset of electric discharge of a thyratron. CONSTITUTION:Magnetic materials 6 such as a plurality of ring-shaped ferrites and ring-shaped amorphous metals are mounted on a central axis 5 at predetermined intervals, and cooling oil is injected from the other end of the central axis 5 and flows out from an opening 51 to the outside to cool the magnetic materials 6. Once one end of the central axis 5 is supplied with a current, the current flows toward the other end flows out from a flange 9 to an external cylinder 7. More specifically, since the plurality of the ring-shaped magnetic materials 6 are provided or the central axis 5, the inductance of the title switch is increased. When the switch is inserted into a laser electric discharge circuit, an initial current starting to flow through a thyratron is hard to flow, and hence energy consumed in the thyratron can be reduced. Hereby, deterioration of the thyratron is reduced and hence a long life of the switch is ensured.

Title: Luminaire for vehicle having discharge bulb
Inventor: TAKASAKI TOSHINOBU
IPC: F21Y101/00
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle luminaire capable of stabilizing the weight of a luminaire body to which a lighting circuit is fixed and decreasing the projecting amount downward in the vehicle luminaire using a discharge bulb as a light source. SOLUTION: A step difference S is formed in the bottom surface of a luminaire body 1 so that the bottom surface 1A of the luminaire body 1 of a lamp part LL having a discharge bulb 5 becomes higher than the bottom surface 1B of a lamp part HL. By fixing a lighting circuit case 16 of the discharge bulb 5 to the bottom surface 1A, the dimension projecting downward of the lighting circuit case 16 in the whole luminaire is decreased, and limitation in body design of an automobile is relaxed. Since a cord connecting the lighting circuit 15 and the discharge bulb 5 is shortened, electromagnetic wave radiation from the cord is suppressed, and influence of EMI on various kinds of on-vehicle electronic devices is decreased.

Title: Vertical shaft pump
Inventor: KONISHI MASAHIDE
IPC: F04D29/70
Filed: 1989-12-27
Abstract: PURPOSE:To prevent foreign materials from flowing in a U-shaped passage by closing the upper end of the U-shaped passage forming member by means of a cover member forming a hanging wall, setting the lower end of the hanging wall below the upper opening end of the U-shaped passage, and communicating the upper opening end with the outside via a space defined by the hanging wall and the U-shaped passage. CONSTITUTION:A level difference between a pumping start water level RWL and a pumping stop water level SWL is properly set by adjusting the levels of the upper end opening portion 12 of a U-shaped passage 21 and the returning point 13 thereof, so that the occurrence of a hunting phenomenon can be prevented. Although a water level rises from a level lower than that of the upper opening end 12 of the passage 21 to the same level as that of the upper opening end 12 and water flows in the passage 21, since the lower end of the hanging wall 35A of a cover member 35 is below the upper opening end 12, foreign materials floating on a water surface can not flow in the passage 21 together with water. Consequently, a good flowing condition in the passage 21 is obtained to avoid the lowering of the performance of pumping start and pumping stop.
