Abstract: An optical semiconductor device comprises: a semiconductor layer in which a resonator is formed; a reflective film covering both end faces of the semiconductor layer; an electrode pad formed by stacking metal layers; a support member arranged in each of positions on a mounting surface close to both the end faces, having a support face with a maximum height from the mounting surface and supporting a holder when the reflective film is coated; and a shield in which a portion higher than a bonding surface extends between each of sides of the mounting surface that are adjacent to both the end faces and the bonding surface so as to cover a region in which the bonding surface is formed in a left-right direction.

Abstract: A control unit for an air conditioning system for a motor vehicle calculates a target blowing air temperature based on a temperature of a passenger's clothing detected by a no contact temperature sensor. An air conditioning operation is performed based on the calculated target blowing air temperature. In particular, when calculating the target temperature in the summer or in the winter season, a change of the detected temperature of the passenger's clothing is used, so that the change of detected temperature is reflected in the target temperature with a time delay.

Abstract: A control unit for an air conditioning system for a motor vehicle calculates a target blowing air temperature based on a temperature of a passenger's dressing detected by a contact-less temperature sensor. An air conditioning operation is performed based on the calculated target blowing air temperature. In particular, when calculating the target temperature in the summer or in the winter season, a change of the detected temperature of the passenger's dressing is used, so that the change of detected temperature is reflected in the target temperature with a time delay.
