Abstract: PURPOSE:To restrict a temperature rise at a central part of downstream side of a catalyst layer from being increased and improve a durability of carrier by a method wherein fuel is supplied to a cental part of the catalyst stored in a mixture flow passage. CONSTITUTION:A catalyst 2 is formed such that a plurality of cylindrical catalyst layers are concentrically and integrally made, and a hollow tube 5 having its downstream end closed is arranged at the central part of the catalyst. A cylindrical wick 8 is closely fitted to an inner surface of the hollow tube 5 and a fuel supplying pipe 9 is removably fitted to a hollow part of the wick 8. When the combustion of the catalyst is started, the catalyst 2 is heated up to a hot temperature under combustion heat, the nearer to the downstream side, the higher the central part of the catalyst. The fuel from the fuel supplying pipe 9 at first cools the downstream side of the catalyst 2, is reversed toward the upstream side through the wick 8 and is gradually gasified while removing the heat from the central part of the catalyst 2, with the result that the downstream side of the catalyst 2 and its central part are cooled to prevent the deterioration of the catalyst 2 and thus the life of the catalyst can excessively be increased.

IPC: G01P3/486
Filed: 1981-08-25
Abstract: PURPOSE:To obtain a tachometer tolerant of external noise light by utilizing the reflected light self-coupling operation of a laser and measuring the number of revolution of a revolving body to be measured. CONSTITUTION:A light emitted from the rear part of a semiconductor laser LD is received by a photodiode D, whose output electric signal is compared with a reference voltage SV to drive the semiconductor laser LD by an amplifier A for an LD driver so that the difference becomes zero. Consequently, the semiconductor laser LD outputs light PD having specified intensity invariably. The output light PD of the semiconductor laser LD is projected on a revolving body RO through a lens. Its projected light is reflected by a reflective film RF to return the light emission surface of the semiconductor laser LD through the lens L. Consequently, a current ID for driving the laser LD varies with the rotation of the body RO and an impulsive voltage is developed across a resistance RO. Its pulses are counted by a counter COU, whose output is displayed on a display device DIS.
