Title: Catalytic combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23C99/00
Filed: 1987-03-16
Abstract: PURPOSE:To shift combustion to the same on a catalyst layer easily and surely by the slight change of air-fuel ratio, by a method wherein a control means air and/or fuel supply, which is operated in conjunction with the temperature detecting means of the catalyst layer, is provided while the flame port of a primary combustion unit is formed so as to be a flat shape, low in flame stability and having no rim substantially. CONSTITUTION:A primary combustion chamber 6 is provided with an oxidizing catalyst layer 9 at the downstream side thereof while the oxidizing catalyst layer 9 is equipped with a thermocouple 12 for detecting temperature, which is operated in conjunction with the solenoid valve 14 of the return pipe 13 of fuel through a control circuit 15. The primary combustion unit 6 is constituted of a tubular body, having a thin tip end, and the upper end of the tubular body, which becomes a flame port 6a, is a flat shape having no rim substantially whereby the flame generates blow-off condition easily by the slight change of an air-fuel ratio. When the thermocouple 12 detects that the temperature of the oxidizing catalyst layer 9 has arrived at a temperature whereat catalyst combustion is effected, the control circuit 15 releases the solenoid valve 14 and a part of fuel is returned into a tank 1 through a return pipe 13. The blow-off condition is generated in the primary combustion unit 6 and mixture gas is discharged as it is unburnt, whereby the catalytic combustion is started on the oxidizing catalyst layer 9 and perfect combustion is effected.

Title: Catalyzer deterioration deciding device
Inventor: OKABE SHINICHI
IPC: F01N3/20
Filed: 1994-03-30
Abstract: PURPOSE:To heighten the accuracy in deciding the degree of catalyzer deterioration by installing a front oxygen sensor and a rear oxygen sensor on the inlet side and on the outlet side of the catalyzer, respectively, and deciding the degree of deterioration based on a response delay, or a period from a time at which the output of the front oxygen sensor becomes lower than a standard value to another time at which the output of the rear oxygen sensor becomes lower than the standard value, taking almost one half the voltage value, or an amplitude, of each output signal as the standard value common to both sensors. CONSTITUTION:A front oxygen sensor 3 is installed in an exhaust pipe 2 on the inlet side of a catalyzer 1, which purifies exhaust gas from an engine, while a rear oxygen sensor 5 is installed in an exhaust pipe 4 on the outlet side. A catalyzer deterioration deciding device 6 is connected to both oxygen sensors 3, 5 so that the deterioration of the catalyzer can be decided from a response delay of both oxygen sensors. When the fuel supply to the engine is cut, the catalyzer deterioration is decided based on the response delay, or a period from a time at which the output of the front oxygen sensor becomes lower than a standard value to another time at which the output of the rear oxygen sensor becomes lower than the standard value, taking almost one half the voltage value, or an amplitude, of each output signal as the standard value common to both sensors. With this, arithmetic processing can be reduced and the accuracy can be hightened.

Title: Solenoid valve
Inventor: RUDORUFU BURUNNERU
IPC: F16K31/06
Filed: 1984-03-30
Abstract: An electromagnetically operable valve, comprising a coil and an electromagnet containing an armature, the armature of which impinges an actuating member connected to or forming an active member of the valve in operating connection and a lever mechanism arranged between the armature and the valve member for the step-up or step-down transmission of the stroke. In valves of this kind known from prior art a considerable expense in construction is incurred for the accommodation of the lever mechanism which offsets the savings with respect to the costs and the constructive area in long-stroke magnets; this is avoided by a novel construction incorporating the lever mechanism into the electromagnet and between the armature and the actuating member.

Abstract: PURPOSE:To ensure an assured prevention for the paper jam of a fixing device, by providing a guide member at the paper exhaustion side of a pressure roll with the tip part touching the circumference surface of the pressure roll and at the same time installing a paper holding saucer near the guide member. CONSTITUTION:A guide member 17 supported by a fixed member 16 stuck to the machine frame is installed nearly vertical to the side of the pressure roll 11. The member 17 is made of a metal or plastic thin plate having an elasticity and touches the circumference surface of the roll 11 of the paper exhaustion side at the tip side. A paper holding saucer 18 is provided under the member 17 by making use of the space area of the main body 1 to store the paper 8 taken off out of the circumference surface of the roll 11. In such constitution, if the passing of the subsequent paper is blocked by a jam caused by the paper passed through a fixing device, the subsequent paper is exhausted onto the saucer 18 and is never stuck round the roll 11. Thus a paper jam can be assuredly prevented.
