This voltage is added to an oscillation input coming from an oscillation circuit II which includes resistances 20, 21, 23, 25, PUT 22 and a capacitor 24. The resulting voltage is amplified to a transformer by an operation amplifier 30 the output from which is delivered 32. The output from the transformer 32 is rectified by a rectifier circuit V and is used for opening and closing a solenoid valve 7. A timer circuit III constituted by contact 26 adapted to be closed when the burner is put on and a capacitor 27 is interposed between the oscillation circuit II and the amplifier circuit IV. When the change of fluctuation of the flame is ceased in a predetermined period of time, the capacitor 27 makes a discharge to hold the output from the amplifier 30.

Title: Refrigerant pump
Inventor: ABE RYOICHI
IPC: F04C29/00
Filed: 1987-05-11
Abstract: PURPOSE:To improve the antiwear proper of slide portions by constituting a thrust bearing of a refrigerant pump from beta type silicon carbide ceramic and enclosed container portions slidably bearing against the thrust bearing from non-magnetic stainless steel. CONSTITUTION:A drive magnet 45 is rotated by driving a motor 43, and a rotor shaft 35 is rotated along with the rotation of a driven magnet 47 coupled magnetically with said magnet 45 to transfer liquid refrigerant. In a refrigerant pump thus operated, a powerful thrust caused by the magnetic coupling of drive magnet 45 with driven magnet 47 is supported by a thrust bearing 51 slidably bearing against an upper shell 42. Said bearing 51 is made of beta type silicon carbide ceramic and the coefficient of friction thereof in combination with the upper shell 42 of non-magnetic stainless steel is considerably small compared with conventional resin materials so that the wear amount of corresponding slide portion is about one twenty fifth of conventional one. Thus, a gap between the driven magnet 47 and the upper shell 42 is held approximately constant to improve the durability and reliability of pump.

Title: Inductor for metal pipe heating
Inventor: ISHIZAKA YUJI
IPC: H05B6/10
Filed: 1987-05-11
Abstract: PURPOSE:To aim at improvement in power efficiency for heating by constituting an inductor with a main conductor to be opposed to a slit of the conveyed metal pipe, an extension conductor being unitized with this main conductor and set up inside the slit and the core attached to the main conductor. CONSTITUTION:A medium-frequency current is made to flow into a main conductor 5 and an extension conductor 7 of an inductor while conveying a metal pipe 2 in the longitudinal direction, and this extension conductor 7 is set up in a slit 4. If so, two circulating passages by an induced current (i) flowing in an edge 2a are formed in both inner circumferential and outer circumferential surfaces of the metal pipe 2, whereby the edge 2a, where the induced current (i) concentratedly flows, is heated. Thus, the induced current (i) flows as being divided into the inner circumferential surface and the outer circumferential surface of the metal pipe 2 at parts other than the edge part and as being extensively dispersed over the whole circumference so that a temperature rise in both inner and outer circumferential surfaces other than the edge 2a is thus checked. With this constitution, heating efficiency in the heating power is conspicuously improved.

Title: Method and apparatus for exposure
Inventor: ATSUMI SHINOBU
IPC: G03F7/20
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To make a microdevice manufacturable in accordance with predetermined production planning by preventing the occurrence of a situation such where the service life of the laser light source of an exposing device ends at an unexpected time and maintenance is required. SOLUTION: In an exposure method, a high-voltage value HV impressed upon the laser oscillator oaf a laser light source is monitored as a parameter for predicting the service life of the laser light source, and when it is discriminated that the mean value of the impressed voltage HV during a prescribed period of time deviates from a prescribed threshold HVmax (for example, 90% of the specified upper limit value for the voltage V), the energy value which is set as the target value for controlling a pulse energy F outputted from the laser oscillator is lowered, for example, from F1 to F2. Since the mean value of the impressed voltage HV drops when the service life of the laser light source approaches its end, the service life of the light source can be prolonged adaptively to the then production planning.
