Abstract: PURPOSE:To produce spheroidal graphite cast iron surely by constituting a titled device of a mold, an agitator dispoed above the mold, a controller which controls the operation of the agitator, a charging device, and an adding device for spheroidizing agents. CONSTITUTION:Molten metal is charged from a charging device 5 into a crucible 7, and spheroidizing agents are added thereto from an adding device 6 for spheroidizing agents. When a detector 17 detects the flow of said molten metal, a circuit part 19 closes switching contacts 14a. Thus, large electric power is supplied to a coil unit 8, and large agitating force is applied to the molten metal in the crucible 7 in the magnetic field generated by the coil unit. Upon lapse of a prescribed time, the contacts 14a are opened, and switching contacts 14b are closed, so that small electric power is supplied to the unit 8. Thus the flow of the molten metal is decreased, slag floats, and the molten metal contg. no slag is charged through a charging nozzle 9 into a mold 2.

Title: Manufacture of heat-fixing roll
Inventor: KON SHUJI
IPC: G03G15/20
Filed: 1987-06-24
Abstract: PURPOSE:To improve productivity of a heat-fixing roll, to prevent a rubber layer of the roll from thermal deterioration, and to stabilize the quality of the roll by inserting a metallic core shaft covered with fluororesin into an induction heating coil and baking the shaft by heating. CONSTITUTION:Fluororesin 2 is covered directly or indirectly interposing a rubber layer on a metallic core shaft 3, then the covered metallic shaft 3 is baked. In this stage, the covered metallic shaft 3 is inserted into an induction heating coil 1, and the shaft is calcined by heating. Since the covering fluororesin 2 is heated quickly to a specified temp. with the induction heating coil 1 fitted to the outside of the shaft and baked, only extremely short heating time is necessary for the calcination. By this process, the productivity of the heat-fixing roll is improved, the thermal deterioration of the rubber layer in accompany with the calcination is prevented, and variation of quality of the roll is eliminated since the whole body of the roll is heated uniformly.

Title: Transmission modulator
Inventor: OFUJI MICHIO
IPC: H04B10/116
Filed: 1991-06-03
Abstract: PURPOSE:To prevent interception of a voice signal by sending a modulated optical signal corresponding to a sound from a sound source and converting the optical signal into a radio wave corresponding to the sound of the sound source and relaying the converted signal so as to reduce leakage electric field strength. CONSTITUTION:A voice output signal of a movie enters an amplification modulator 12 from a movie set 11, in which the signal is amplified and modulated and the result is sent to an infrared ray transmitter 13. The infrared ray transmitter 13 emits a modulated infrared ray signal 22 and gives the signal 22 to a relay pole 25. The signal is converted into a voice output signal corresponding to the voice output signal of the sound source by the converter and sent to an FM car radio set 50 as an FM radio wave 90. Then a movie voice is reproduced from the FM car radio set 50. Thus, leaked electric field due to leakage of a radio wave between the sound source and the relay means is reduced and interception is prevented.

Abstract: PURPOSE:To prevent the efficiency of power generation from being decreased by a means for boosting the pressure of reformed gas by providing a steam ejector in a desulfurizing recycling gas line, and supplying the steam of a steam separator to the steam ejector. CONSTITUTION:A steam ejector 10 provided in a desulfurizing recycling line 11 is supplied with steam from a steam separator 3 that generates steam by means of heat generated by a fuel cell 7. With the steam as a drive source, part of reformed gas produced by a reformer 4 has its pressure boosted, is mixed with the steam, and supplied to a region upstream of a desulfurizer 1.

Title: Automatic clearance adjuster for brake
Inventor: IKEGAMI HIROSHI
IPC: F16D65/56
Filed: 1987-06-26
Abstract: PURPOSE:To improve the durability in a title device as well as to facilitate the setting work of a normal working clearance in the initial stage by having an automatic clearance adjuster built in a cylinder body, and making an adjuster nut so as to be automatically adjusted by an operating piston or the like. CONSTITUTION:If brake fluid is fed to a hydraulic chamber 12, each of brake shoes 11 and 24 is slidden to a brake drum, thus braking effort is securable. Now, if a working clearance is within the normal clearance, an operating piston 5 receives hydraulic pressure, and an adjuster nut 16 receives the resilient force of a spring 19 so that they are solidly operated forward within the range of backlash of a reversible screw 17, thus the braking force is secured. When the brake shoe 11 is worn out and the working clearance is larger than the normal clearance, the backlash of the reversible screw 17 is reduced and then the operating piston 5 is further operated forward. At this time, a clutch 18 is disengaged, while the adjuster nut 16 receives the resilient force of the spring 19 and thereby it is screwed out by the reversible screw 17, thus the working clearance is automatically adjusted.

Title: Exhaust device of two-cycle engine
Inventor: MIKAMI TOSHIO
IPC: F02B75/02
Filed: 1984-07-30
Abstract: PURPOSE:To have a high output power both at low and high speed by inserting the tail part of the exhaust pipe in the expansion chamber of maffler, putting an external cylinder rotatably in the tail part of exhaust pipe, and allowing this external cylinder to rotate in accordance with the revolving speed of engine, and thereby putting the exhaust pipe in communication with the expansion chamber selectively. CONSTITUTION:In low speed range of engine, a plurality of horizontal holes 4 provided in that portion of exhaust pipe 1, which is inserted into the expansion chamber 3 of muffler 2, are shut by an external cylinder 5 fitted on the exhaust pipe 1 rotatably. This secures the exhaust pipe 1 with sufficient length as well as provides pulsation effect in the low speed range to lead to high output. In the high speed range, on the other hand, said external cylinder 5 is rotated by a lever 7 working interlocked with revolutions of the engine so that horizontal holes 6 provided in the external cylinder 5 mate with the above-mentioned horizontal holes 4 in the wall of exhaust pipe 1. This allows the exhaust gas, which comes up through the exhaust pipe 1, to flow into the expansion chamber 3 through the horizontal holes 4, 6. Thus the same effect is obtained as shortening of exhaust pipe 1, which can enhance the output through accomplishment of pulsation effect even in high speed range.
