Title: Kerosene burner
Inventor: NAKAMURA KAZUHARU
IPC: F23D5/12
Filed: 1984-12-03
Abstract: PURPOSE:To enable to nearly perfectly remove the malodor at the fire extinction for a long term by forming a structure wherein a porous plate catalyzer is arranged in a vaporized gas ascending passage at a position higher than a fuel feeding port and the main combustion zone of mixed gas is formed above the plate catalyzer. CONSTITUTION:A porous plate catalyzer 5 is arranged in a vaporized gas ascending passage at a position higher than a fuel feeding port 4 in a pot 1. The mixed gas past through the porous plate catalyzer 5 is caused to be burnt completely in a main combustion zone located above the pot 1. The temperature of the completely burnt mixed gas does not rise extremely high and remains to be as low as the temperature of a mixing member 3. Further, though the catalyst has little effect during normal combustion, the porous plate catalyzer 5 completely oxidizes the vaporized gas, the amount of which becomes smaller, after the fire extinguishing operation. On the other hand, even the state that dense vaporized gas exists on the bottom surface 1' of the pot 1 just after the fire extinction occurs, said dense vaporized gas gradually disperse and passes through the plate catalyzer 5 and consequently no malodor is discharged outside a burner.

Title: Drive method for pulse motor
Inventor: YANAGIURA TAKASHI
IPC: H02P8/14
Filed: 1986-10-28
Abstract: PURPOSE:To conduct initial drive up to a home position positively without using a sensor by driving a pulse motor in the fixed direction of rotation by self-start excitation extending over steps in the same number as the number of excitation phases before starting. CONSTITUTION:A pulse motor is excited at the predetermined self-start pulse rate of high torque of steps in the same number as the phase number of a four-phase motor, four steps. The speed of the pulse motor is held until the vibrations of a rotor are damped so that out-of-step due to resonance on acceleration is not generated at four steps (four phase), and speed is increased gradually through a conventional acceleration method. The number of steps where the motor is turned in one direction (in the intentional direction of rotation) can be taken by two steps or more even when the motor is stopped in any phase first by performing self-start excitation at four steps, thus accelerating the motor in the intentional direction.

Filed: 1984-12-07
Abstract: PURPOSE:To obtain a gas-insulated transformer which is highly reliable in insulation, by gas-dividing and placing a non-linear resistance element for suppressing potential oscillation in a pressure-resistant insulating cylinder, and making the gas pressure of the non-linear resistance element side higher than in the main body of the transformer. CONSTITUTION:A non-linear resistance element 15 to be provided on a high-voltage winding 4 is disposed so as to be received within a pressure-resistant insulating cylinder 16. The pressure-resistant insulating cylinder 16 has one end thereof fixed to the core 1 side and the other end thereof airtightly opened in a tank 8, and this opening is airtightly provided with a cover 17. An insulating gas 18 such as SF6 gas is sealed in the pressure-resistant insulating cylinder 16 with a pressure higher than the insulating gas 19 of the main body side in the tank 8. In a case of penetration of a surge voltage, potential oscillation is suppressed because of the non-linear resistance element 15 being connected. In addition, since the insulating gas 18 is sealed in the pressure- resistant insulating cylinder 16 with a high pressure, the dielectric strength of the surface of the non-linear resistance element 15 becomes high. Moreover, since the non-linear resistance element 15 is gas-divided from the main body side, inspection or repair can readily be performed.
