Title: Fuel injector
Inventor: SUDA KOUICHI
IPC: F02M69/00
Filed: 1980-06-11
Abstract: PURPOSE: To stabilize performance in high temperature and improve durability of the equipment in such a way that a fuel path is formed inside the core, and fuel from a fuel pump is forcibly flowed through the fuel path into a fuel pressure regulator.  
     CONSTITUTION: A fuel path 21a is formed on the core 21 of a fuel injector 20, a coil 23 is wound up around a bobbin 22 positioned bordering on the core 21, and its terminal block is connected through a terminal 24 to an electronic controller (unshown in the figure). Fuel which is discharged from a fuel pump 2 comes through  the fuel path 21a of a fuel injector 20 to a needle 26, part of which is injected  through between a needle 26 and a seal 27 into the engine, and the remainder flows  through a port 28 into a fuel pressure regulator 4. In that event, since fuel absorbs  heat of the coil 23 itself and conductive radiant heat, etc., it can prevent the coil  part from rise in the temperature, increase high temperature performance, and preclude the coil 23 from seizure, etc.

IPC: E04H7/18
Filed: 1982-05-10
Abstract: PURPOSE:To reduce the weight of a cryostat roof itself and thickness of a roof material and side wall material for cost reduction by insulating the cryostat roof from heat with a film structure. CONSTITUTION:A storage section 3 has the bottom 3a and the side wall 3b respectively formed with double structures of inner tank 4 and outer tank 5, and a keeping cool material 6 is filled between both tanks. A dome-like roof 2 is mounted on the upper end of the side wall. The whole storage section exposed to the ground surface is covered with a film structure 8 made of materials like lattice film to form a space 9 insulated from the atmosphere. The film structure 8 is expanded by blowing air into the space 9 through a pipe 16 from a blower 17. Air is cooled and blown then so that the keeping-cool effect is improved. When the film structure is of double structure, the keeping-cool is further improved.

Abstract: PURPOSE:To easily practice a piercing work for a relatively short sized material, by pushing a piercing plug into a round bar shaped blank along its central axis in order to apply a piercing work, while rotating and pressing the round bar shaped blank with a couple of press rolls rotating in the same direction. CONSTITUTION:A short sized, round bar shaped blank S is put between a piercing plug 9 and a blank holding jig 71, and is rigidly clamped by upper and lower rolls 1, 2. The upper and lower rolls 1, 2 are rotated in the same direction, and their roll gap is narrowed. Hereby, one or more turns of rolling compression are given to the blank S. At the same time, a plug 9 is pushed into the blank S along its central axis, that is, the piercing work is applied to the blank S. Since the pierced part Sa of the blank S is restrained by guides 8, the flattening deformation of the pierced part Sa is restrained. The press rolls 1, 2 are then released from the load, their roll gap is widened, and the blank S is finished between the guides 8. Moreover, by attaching suitable dies to the surface of upper and lower rolls 1, 2, a stepped uneven pattern is formed in the surface of the blank S.

Filed: 1986-04-09
Abstract: PURPOSE:To synchronize the speeds of both right and left shift levers and to speed up and ease an operation and inspection by disposing the cylinders of said levers on the side near the center of a roll turn table to trancated chevron shape and forming triangular actuating links thereof into a anti-congruent type. CONSTITUTION:The cylinders 8 of the right and left roll shift levers 6 on the side near the center 12 of the turn table 1 for moving in and out of the rolls are disposed to trancated chevron shape and the cylinders on the other side are disposed in approximately parallel with the axial direction of a rolling mill. The link shape of the link mechanism constituted of pins 7 at the rotating center of the shift levers 6, trunnion pins 10 of the shift cylinders 8, and pins 9 for connecting the shift cylinders 8 and shift levers 6 is made into the anti- congruent type in the right and left shift lever mechanisms. The speeds of the two levers 6 are synchronized in such mechanism. The spacing S between the two adjacently provided cylinders 8 is widened to permit easy inspection. The distance l between the center of the rolling mill and the center 12 of the turn table 11 is shortened to decrease the floor area of the device and to speed up the roll change operation. The operating efficiency is thus improved.

Title: Molding metal mold of rubber
Inventor: OOTSUBO HISAKI
IPC: B29C45/00
Filed: 1978-06-30
Abstract: PURPOSE: To shorten vulcanization time, by forming one portion of a material passage of a metal mold in a thin shape, and by mounting a heating means to said thin shape portion.  
     CONSTITUTION: Plastic compound preheated is projected into a metal mold 10 from a projection nozzle 1. Compound projected into the metal mold 10 is injected to cavities 19 through a spool 15, a runner 17 and gates 18. In this case, the temperature of an outer surface of a torpedo 13, in which a heater 16 is buried, becomes to temperature, which can be increased, in cooperation with the frictional heat of compound up to temperature near approximate vulcanization temperature at a point of time when compound reaches the cavities 19. Thus, the temperature of the compound projected from the projection nozzle 1 rises up to temperature near appro imate vulcanization temperature because frictional heat is generated during the time when the compound passes through the spool 15 since the portion is thin and cylindrical and heat is smoothly transmitted from the torpedo 13.

Title: Load carrying facility
Inventor: KITA HIROAKI
IPC: G05D1/02
Filed: 1991-04-15
Abstract: PURPOSE:To present a load carrying facility having the carrying efficiently improved by enabling free-running truck to move back. CONSTITUTION:A free-running truck 2 is provided with a covered distance detecting means which detects the covered distance from the base point of a running rail, a transmission/reception means to a ground controller 1, and a main body controller 8, and this controller 8 compares the distance from the base point to the distination inputted from the transmission/reception means with the covered distance inputted from the covered distance detecting means and runs its own free-running truck in the opposite direction when judging that the destination is within a prescribed distance range and is in the direction opposite to the normal running direction. The distance from the base point to the destination and the covered distance of its own free-running truck are compared with each other; and when it is judged that the destination is within the prescribed distance range and is in the direction opposite to the normal running direction, the free-running truck is run in the opposite direction; and thereby, one circulation of the free-running truck 2 is unnecessary to shorten the carrying time. Thus, the carrying efficiently is improved.

Title: Electrolyzing method
Inventor: TAKESUE MASAHIRO
IPC: C25B9/19
Filed: 1984-04-23
Abstract: PURPOSE:To suppress an increase in liquid temp. and to improve electrolyzing efficiency in cation exchange membrane electrolysis of an aq. alkaline metallic salt soln. by increasing the inside pressure of an anode chamber to make hydrophilic the membrane, bringing the membrane into contact with a cathode surface and decreasing the electrolytic voltage under the strong current at the specific current density or above. CONSTITUTION:The cation exchange membrane consisting essentially of carboxylic acid which is perfluorocarbon is interposed in the spacing where anode and cathode surfaces are spaced from each other at >=0.5mm. and about 1-4mm.. The membrane is brought into contact with the cathode surface by exerting 10- 100cm H2O pressure to the aq. alkaline metallic salt soln. in the anode chamber. The surface of the membrane on the side in contact with the cathode surface is preliminarily made hydrophilic by providing about 1-3mu ruggedness thereto by chemical plating of platinum. The electrolytic voltage is decreased by >=0.2V even with >=40A/dm<2> current conduction which is not possible in the conventional practice. The failure of the membrane and the increase of the liquid temp. are thus suppressed. The electrolyzing efficiency is thus improved by the safe increase in the electrolytic current efficiency.
