Abstract: PURPOSE:To detect leakage of gas from a gas pipe connected to each gas combustion apparatus before combustion is started, by providing a controller to drive solenoid valves, as well as to receive a signal from a gas pressure sensor fitted in the position of a gas pipe at the inlet of a combustion apparatus. CONSTITUTION:A gas pressure sensor 8 is provided between a gas control valve 10 to control gas rate to the burner 9 of a combustion apparatus together with a gas governer 11, and a gas pipe 7. A controller 12 drives a gas solenoid valve 6, as well as to receive a signal from the gas pressure sensor 8. Whether the inside of a gas pipe is under the specified pressure without gas leakage or not is checked in the non-combustion time before the burner gets into a combustion mode, in such a manner that a signal from the gas pressure sensor 8 is fed into the controller 12 in the state that a solenoid valve SV1 is opened and a solenoid valve SV2 is closed as long as a predetermined time (t1-t2). The gas pressure sensor 8 will not give a predetermined value to the controller even if gas leakage at the degree no enough to actuate a gas shut down mechanism is occurring, so that the controller 2 can decide gas leakage from the gas pipe line, and can close the solenoid valve 6 afterwards.

Title: Stepping motor
Inventor: YAMAMOTO MASARU
IPC: H02K37/16
Filed: 1991-05-24
Abstract: PURPOSE:To alleviate a holding torque to realize driving with a small electrical power by causing pole sections of a first yoke and a second yoke to show poles in different polarities due to a permanent magnet while the power source is not supplied. CONSTITUTION:A permanent magnet 31 is provided between an upper first yoke 29 and a lower second yoke 30 with the upper surface defined as N-pole while the lower surface as S-pole. In the case of supplying no electrical power to a stepping motor, poles of different polarities appear at the pole end of the first yoke 1 and that of the second yoke 30 due to the operation of the permanent magnet 31. Therefore, a rotor 21 receives a repulsive force against the one yoke and an attractive force for the other yoke. A holding torque thereof is reduced due to simultaneous effect of the repulsion and attraction. When electrical power is supplied to the stepping motor, electromagnets 25 to 28 are energized, magnetizing the first and second yokes in the same direction to rotate the rotor 21.
