IPC: F02M37/00
Filed: 1991-01-19
Abstract: PURPOSE:To thaw the frozen fuel in the case where fuel is frozen in a part in a fuel feeder at cold climate, and thereby an engine fails to start. CONSTITUTION:A fuel return passage 5 of a fuel feeder is short-circuited to a fuel feed passage at a short passage 6. With short-circuiting, fuel is circulated around through those of short passage 6, fuel feed passage 2, fuel filter 3, fuel injection pump 4, fuel return passage 5 and short passage 6 in order, thus a short circulating passage 8 is formed in this way. Then, a temperature sensor 0, an electric heater 10 and an electric motor 11 are all installed in this short circulating passage 8, and when the detected temperature of this temperature sensor 9 is less than the setting temperature, the heater 10 and the pump 11 are operated via a control unit 12. Thus, the fuel is circulated around as heating it by means of electric control like this, through which frozen fuel is thawed. With this constitution, the frozen fuel is thawable earlier in a simple manner.

Abstract: PURPOSE: To confine light in an active layer, and to make possible laser oscillation by reducing the loss of light emitted to the outside of the active layer of a nitride semiconductor laser element by making the stripe width fo an N-type nitride semiconductor layer narrower than the width of a substrate. CONSTITUTION: At least N-type nitride semiconductor layers and P-type nitride semiconductor layers are laminated successively on a substrate 1 in an electrode stripe type laser element, and the laser element is formed in a striped shape. Since the width (b) of the N-type nitride semiconductor layer 2 electrically connected to a negative electrode 10 is made smaller than that (a) of the substrate 1 so that the emission of an active layer 5 can not spread to the N-type nitride semiconductor layer 2, the emission of the active layer 5 is confined into the striped nitride semiconductor layers and loss is reduced, and oscillation is possible at all times. When the favorable stripe width (b) of the N-type nitride semiconductor layers is set in 1-50μm, emission is not spread and a threshold current is not increased, and difficulty on manufacture is not generated.
