Title: Combustion device
Inventor: HIRATA YASUSHI
IPC: F23D14/18
Filed: 1986-03-25
Abstract: PURPOSE:To obtain a combustion device, wide in the regulating range of the amount of combustion and stable in combustion, by providing a far infrared rays radiating coating on the inner wall surface of a burner head. CONSTITUTION:Far infrared rays radiating coating 4, which consists of polyborosiloxane resin, zirconia, alumina and solvent, is applied to the inner wall surface of a burner head 1. Fuel and air, injected from a fuel nozzle 11 and an air discharging port 12, are premixed in a heated evaporating tube 6 and are changed into premixed gas, thereafter, the premixed gas is injected from the flame port 2 of a burner head 1 through a gas passageway 9 and forms flames on the surface of a wire net 3. Far infrared rays radiating coating 4 is applied to the inner wall surface of the burner head 1, therefore, an emmisivity from the burner head 1 is increased whereby the temperature increase of the burner head 1 is restricted, the temperature of the flame port wire net 3 is reduced and the heat resistant property of a combustion part C is improved. According to this method, a combustion device, in which the deformation as well as the breakage of the combustion part C are eliminated, the regulating range of the amount of combustion is widened and the generation of poisonous discharging substances is very little, may be obtained.

IPC: B62D55/30
Filed: 1995-03-01
Abstract: PURPOSE: To sharply improve the reliability by preventing damage from occurring at the screw end, etc., between the rod on the other side of a tension adjusting cylinder and a nut by the use for a long period. CONSTITUTION: On the insider periphery side of a nut 32 is an annular release groove 33 made between the end face 32A and an internal thread part 32B, and release groove 33 surrounds the end, etc., of the external thread part 15A of the rod 15 on the other side all around from periphery side. Hereby, the screw end part 34 between the external thread part 15A and a nut 232 can be separated largely from the side of abutment with a spring receiver 16 on the other side, so even in case that the nut 32 repeats the collision against the spring receiver 16 on the other side, the interposition of the escape groove 33 can prevent the collision force at this time from working directly on the screw end 34 between the external thread part 15A of the rod 15 on the other side and the nut 32.

Abstract: PURPOSE:To reduce power consumption without simultaneous turning-on of plural analog switches by setting a ratio of the width of P-channel and N- channel transistors(TRs) to the length of a gate to a different value from 1st and 2nd CMOS inverters. CONSTITUTION:Let a ratio of the ratio of the width of a P-channel TR3 to the length of the gate to the ratio of the width of an N-channel TR4 to the length of a gate be A, then let a ratio of the ratio of the width of a P-channel TR8 to the length of the gate to the ratio of the width of an N-channel TR9 to the length of the gate be B. The ratios A, B are set different to form the threshold level of CMOS inverters 5, 10 different. Thus, when an input waveform is applied to an input terminal 1, the simultaneous turning-on of a 1st analog switch 12 and a 2nd analog switch 13 is avoided, and the circuit is operated with a prescribed time difference. Thus, the power consumption is reduced.
