Abstract: The present invention provides a Vertical Cavity Surface Emitting Laser including: a first multilayer film reflector; an active layer having a light emission region; a second multilayer film reflector; and a reflectance adjustment layer in this order on a substrate side. The first multilayer film reflector and the second multilayer film reflector have a laminated structure in which reflectance of oscillation wavelength λx is almost constant without depending on temperature change. The active layer is made of a material with which a maximum gain is obtained at temperature higher than ambient temperature. The reflectance adjustment layer has a laminated structure in which difference ΔR(=Rx−Ry) between reflectance Rx of a region opposed to a central region of the light emission region and reflectance Ry of a region opposed to an outer edge region of the light emission region is increased associated with temperature increase from ambient temperature to high temperature.

Abstract: A combustion variation value is detected, and a function that uses the detected combustion variation value is added to CVAR(i−1) to obtain CVAR(i); and using the resulting value, an exhaust gas recirculation amount and an ignition timing are obtained. A combustion variation is detected, and if the detected combustion variation value is equal to or greater than a predetermined value, the value of flag is set to be 1, and the exhaust gas recirculation amount and the ignition timing are reset to previous values. If the detected combustion variation value is less than the predetermined value, the value of the flag is set to be zero, and a current combustion variation manipulation correcting amount CVAR(i) is updated. If the value of flag is 1, the process is immediately terminated.

Abstract: A tuner unit includes a unit board. The unit board is formed, at its lower end, with a protrusion to have a terminal pattern formed on the protrusion. A frame chassis has a side plate having, at its lower end, a protrusion having a tapered side face in one of side faces. When the protrusion of the unit board is inserted in a hole of a main board, the tapered side face is inserted while abutted against an inner edge of a hole of the main board. This urges the protrusion in a direction that the terminal pattern is brought close to the connection pattern of the main board.

Abstract: A part holder includes a part holding portion. In this part holding portion, a leadless part is held by a part receiving portion and an engaging piece. In such a state, the leadless part is inserted in a hole formed in a printed circuit board. At this time, a resilient piece provided on a leg of the part holder comes into abutment against an inner edge of the hole, whereby the part holder is fixed by the hole. Also, the part inserted in the hole is urged onto one surface of the hole by a resilient portion of the part holder. Thus, a pattern formed on one main surface of the part is closely contacted with a pattern formed on a backside of the printed circuit board.
