Patent JP-H05258752-A (JP)
Title: Manufacture of grating for lead-acid storage battery
IPC: B21D31/04
Filed: 1992-03-11
Abstract: PURPOSE:To enlarge the vertical length of each mesh by enlarging the maximal amount of expansion at the time of expanding a lead alloy made thin plate through heating the lead alloy made thin plate at a specified temperature not exceeding a temperature capable of recrystallizing it and then subjecting it to expanding operation. CONSTITUTION:A plurality of parallel slits 3 each having a length K are formed, in a zigzag manner, in a lead alloy made thin plate 2 whose grating 1 contains no antimony or only a small amount of antimony if any, in the horizontal direction thereof. The thin plate 2 is expanded orthogonally to the slits 3, thereby being subjected to expanding operation. In this case, after heated at a specified temperature not exceeding a temperature capable of recrystallization of the thin plate 2, this thin plate is expanded, by which the maximal amount of expansion at the time of expanding the thin plate 2 becomes large. As a result, the vertical length of each mesh 4 becomes large. This makes low the electrical resistance of the mesh gratings so as to facilitate the takeout of a large current necessary at the time of, for example, an engine start.

Title: Controller of refrigerator with freezer
Inventor: SUZUKI NAMIHEI
IPC: H02P6/08
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To provide the stable rotation to the fluctuation in the load torque by controlling the time from the reference rotational position in the rotor rotational period of a sensorless DC brushless motor to the appropriate energization control timing of the energizing phase as the energization control timing. SOLUTION: A pulse delay means 2 receives the output of a rotor position detecting means 1, and calculates the timing delayed by the time corresponding to a prescribed electrical angle from the period of the zero-cross pint (the reference rotational position) of energization phases 8, 9, 10. The delay pulse train is generated as the energization timing signal of each phase. An energization control generating means 3 obtains and outputs the generation timing of the energization control signal corresponding the delay pulse train from the pulse delay means 2 to the pulse train from the rotor position detecting means 1. Even when the load torque is different to the rotational angel, and the rotational speed is fluctuated, the optimum energization switching timing is obtained and the efficiency of the motor is improved.

Title: Mirror structure for synthesizing laser beam
Inventor: YAMANOUCHI YASUSHI
IPC: G02B27/14
Filed: 1995-02-17
Abstract: PURPOSE: To adequately synthesizes a laser beam of particularly a large power and a laser beam of a smaller power and to suppress the temp. rise of the mirror of a mirror structure for synthesizing two kinds of the laser beams varying in the powers and releasing the synthesized beam so as to have the same optical axis. CONSTITUTION: A through-hole 1a allowing the passage of the second laser beam LBw of the small power is formed in the central part of the mirror 1 having the reflection surface for the first laser beam LBs of the large power. Since the mirror 1 is formed of a total reflection type, groove holes 1b for passing a refrigerant are formable therein. The temp. rise of the mirror 1 is sufficiently suppressed as compared with the case of the transmission type mirrors, like the conventional mirrors, which allow the passage of the laser beam LBw . The burn thereof is thus prevented.

Title: Differential pressure piston for gas tracking
Inventor: YOSHIDA SADAYOSHI
IPC: F16K17/36
Filed: 1981-04-09
Abstract: PURPOSE:To obtain a fire hazard proof apparatus with high safety by a method wherein the change of gas itself flowing within a piping is measured and controlled by comparison on the association with apparatus in other system and its flow rate, flow direction and thermal change are detected so as to immediately stop the supply of gas in a main pipe part when the detected state turns to be dangerous. CONSTITUTION:When the differential pressure piston for gas tracking 8 is stopped in the state shifted leftward, the first two reed switches out of four ones 19 are put into operation in order to send a signal telling that gas has flowed to the comparing timer of a thermal detecting unit. At this time, when thermal reaction occurs at the thermal detecting unit, said signal sent to the comparison timer is cut-off and successive supply of gas is resulted. After that, when flame of gas is extinguished from one sause or another, the resultant internal change  of the thermal detecting unit causes to output a signal in order to issue a command to a shut-off valve in a main pipe part so as to stop the supply of gas.  Simultaneously an alarm is issued.

Title: Injection mold
Inventor: SUGIYAMA KOJI
IPC: B29C45/73
Filed: 1994-03-24
Abstract: PURPOSE:To provide an injection mold, which is simple in structure and greatly improves cooling efficiency. CONSTITUTION:Both molds on a fixed side and on a movable side are constituted by assembling a plurality of mold bases 3 to 8 and, at the time of mold opening after injection is finished, each of the mold bases 3 to 8 is automatically spaced from one another by resilient members 26, 27. Accordingly, the handling of the molds naturally becomes easy, and the cooling efficiency of the molds can be increased without particularly setting other complicated mechanisms. In particular, since the main mold bases 5, 8 on the fixed and movable sides, having a cavity, are temporarily separated from the other mold bases 3, 4; 6, 7, respectively, their latent heat is rapidly lowered to accelerate cooling, and an injection molding process can be expedited at high speed without increasing production cost.

Abstract: PURPOSE:To release coagulated glass attached to the inner face of pipe wall and to prevent clogging, by setting a temperature control means to provide an off-gas flow with temperature difference on the pipe wall in the vicinity of an opening of an off-gas exhaust pipe communicated with the interior of a melting tank. CONSTITUTION:An off-gas exhaust pipe 8 is set in a communicated state in a melting tank 1 and a jacket 9 surrounding the vicinity of an opening 8a of the off-gas exhaust pipe 8 is laid in a stuck state to a pipe wall. When coagulated glass G1 is attached to an inner wall face in the vicinity of the opening 8a of the off-gas exhaust pipe 8, cooling water is sent from a cooling water supply system 11 to a flow channel 10 in the jacket 9. Consequently, the pipe wall of the off-gas exhaust pipe 8 and the attached coagulated glass G1 are cooled to cause shrinkage. In the operation, since coefficient of thermal expansion of the off-gas exhaust pipe 8 is larger than that of the coagulated glass G1, the amount of the shrinkage is enlarged, shear is produced between the boundary part of them and the coagulated glass G1 is released from the wall face.

Abstract: PURPOSE:To uniformly activate the electron emission substance which is spread on the electrode of a discharge lamp without enclosing mercury, by using in parallel, the electric conductive heating and activation caused by discharge between the both ends of an electrode in inert gas. CONSTITUTION:An electrode 3 of a discharge lamp is coated with electron emission substance E made of ternary carbonate.

In this case, the current is adjusted so as to properly activate a central part A. At the time when CO gas and CO2 gas produced through this activation are almost exhausted, inert gas is enclosed in the bulb 1 through an exhaust pipe 4, and a high-frequency pulse voltage is impressed on both ends 3a, 3b of the electrode 3. Thereupon, the discharge is produced, the both ends B, B are heated, and the inactivated parts of the substance E are activated.
