Title: Reciprocating pump and reciprocating pump device
Inventor: KAWAGUCHI HIROSUKE
IPC: F04B53/10
Filed: 1993-06-22
Abstract: PURPOSE:To increase a peak value of a discharge pressure in a plunger pump which intermittently injects water with high pressure while utilizing pulsative motion of discharge pressure together with a suction/discharge cycle. CONSTITUTION:A pump chamber 28, varied inits volume by reciprocation of a plunger 26, is communicated with a storage chamber 60. A piston 62 is energized in a direction of decreasing the volume of the storage chamber 60 by a compressive coil spring 68. A secondary discharge valve 70 always interrupts the connection between the storage chamber 60 and a secondary discharge port 56 by means of a compressive coil spring 72. An operation bar 76 has a base end screwed to a leading end of the plunger 26, and has a leading end in abutment against a secondary discharge valve 70 in the vicinity of a top dead center of the plunger 26, for forcibly opening the secondary discharge valve 70.

Title: Discharge lamp, lamp device and liquid crystal projector
Inventor: KAWASHIMA HIROMICHI
IPC: H01J61/20
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent generation of discharge at the root. SOLUTION: A discharge lamp comprises: an air-tight container 2 made of quartz glass; a discharge medium enclosed inside the air-tight container 2 and including at least metal halide; an anode 5 and a cathode 6 disposed opposite to each other inside the air-tight container 2 with a predetermined interval therebetween; and a projection 8 projecting toward the anode 5 around a portion where the cathode 6 penetrates at the inner circumferential surface of the air-tight container 2. Although the metal halide inside the air-tight container 2 is vaporized during lighting while solidified when extinguished, the formation of the projection 8 formed at the root of the cathode 6 can prevent the solidified metal halide from staying at the root of the cathode 6, thereby preventing generation of discharge at the root during the lighting.

Title: Coil winding apparatus
Inventor: HAMANE TOKUHITO
IPC: H02K15/04
Filed: 1980-12-09
Abstract: PURPOSE:To eliminate possible elongation and flaw of a coil when it is raked down by bending a slant plate up at the position deviated to the axis from the point at which the slant plate engages a transmission means. CONSTITUTION:A slant plate 11 is bent at a mobile winding frame 3b up to an angle greater than that of the inclination thereof. The proper bending position is located on the side of axis from a transmission means comprising a spherical bearing 8 and a bearing holder 9. In this example, the slant plate is bent at the axis. This maintains the height of the lower dead point constant at a coil holding rod 5b of the mobile winding frame regardless of the position of the mobile winding frame 3b. Therefore, a slightly greater length of the coil holding rod 5b than that of the coil holding rod 5a enables the coil to be lowered almost horizontally with the coil holding rods 5 even when the coil is formed according to any laying thickness.

Abstract: PURPOSE:To prevent the hazard of oils being mixed by pulling out a key from a lock after locking with an intermediate valve closed, and running a trailer tank truck leaving a brake lever for a trailer on a driver seat unlocked with this key. CONSTITUTION:A first locking mechanism 32 for locking an opening and closing lever 30 for an intermediate valve 18 on a first discharging pipe 16a when it is closed and a second locking mechanism 62 for locking a brake lever 60 for a trailer on a driver seat in a tractor 56 upon brake application are alternately locked and released with a key of the same kind. In doing so, a trailer tank truck, unable to lock and release the trailer brake lever 60 without the intermediate valve 18 being closed, cannot travel to the next loading location. This method prevents an operator from forgetting to close the intermediate valve 18 after being opened. A key pulled out of a first lock 44 after locking the opening and closing lever 30 by inserting the same thereinto with the intermediate valve 18 closed is inserted into a lock hole 72 of a second lock 64 on the trailer brake lever 60 to run the trailer tank truck leaving a brake lever unlocked.
