IPC: F02D41/00
Filed: 1986-01-31
Abstract: PURPOSE:To prevent an over rich state caused by a choke, by controlling air- fuel ratio, when an engine temperature is in a predetermined value or less, while returning an air-fuel ratio correction value, when it reaches an upper limit value, to the fixed correction value when the engine temperature increases to the predetermined value or more, in the case of an engine having an automatic choke mechanism. CONSTITUTION:An output from an O2 sensor 18 is input to a control part 14, comprising a reference voltage comparator circuit 20, input circuit 26, CPU28 and an output circuit 30, and a valve 16 in a carburetor 6 is controlled through the output circuit 30, regulating air-fuel ratio.

Title: Solid state laser oscillator
Inventor: ISHIKAWA KEN
IPC: H01S3/042
Filed: 1986-01-31
Abstract: PURPOSE:To prevent the center part along the axial direction of a laser material from being heated more than the other part and prevent a large thermal stress from being induced in the center part to avoid cracking by a method wherein the distribution of the temperature rise along the axial direction of the laser material is approximately made uniform over the whole length. CONSTITUTION:As some portions of the lights outputted from exciting lamps 4 are scattered by a light reducing part 11 of 1st flow pipe 5 in which a laser rod 3 is housed, the luminance of the exciting light applied to the center part along the axial direction of the laser rod 3 is almost the same as those of the lights applied to both end parts. If the luminance of the exciting light applied to the center part along the axial direction of the laser rod 3 is made to be almost the same as those of the lights applied to both end parts, the temperature of the laser rod 3 rises approximately uniform over the whole length along the axial direction. With this constitution, the temperature rise at the center part along the axial direction of the laser rod 3 higher than the rises at both ends of the rod 3, which is induced by the increase of the input power to the exciting lamps 4 for the purpose of obtaining a high power laser beam L, can be avoided so that a large thermal stress at the center part along the axial direction which creates crackings can be avoided.
