    摘要: For evaporating a protective coating on a light emitting end surface 51a of a laser chip 51, there is formed first an Si film 52a, which is free from generation of oxygen due to decomposition. Thus, there is created a coating in the vicinity of the light emitting end surface 51a immediately after start of evaporation process under conditions of low partial pressure of oxygen. At the same time, in the later evaporation process of the protective coating 52b, if oxygen is generated due to decomposition of the evaporation material Al2O3, and oxygen partial pressure is increased, collision or bonding of the oxygen with the end surface 51a is prevented, thereby decreasing damages given to the end surface 51a in the process of protective coating creation. Further, the Si film 52a has a film thickness as small as approx. 20 Å. This controls generation of leakage current in the Si film 52a (or the end surface 51a), and prevents negative influence on oscillation characteristics.

    摘要: An antenna structure for vehicles capable of minimizing the distance between a first contact member and a signal processing circuit and ensuring stable antenna performance without using a connection line of a lengthy wire rod is provided. To realize this advantage, an antenna element is disposed on a rear window glass, and the first contact member is disposed at an end of the antenna element. Further, an amplifier case having an attachment flange facing the rear window glass is fixed to a roof panel, and the signal processing circuit is disposed in the amplifier case at a position sandwiching the attachment flange.

    摘要: The present invention relates to a semiconductor laser device having a protective coating with a high-reliability formed on an end surface, and to a method for manufacturing the same. According to the present invention, in forming a semiconductor laser device, an electrode comprising Au is patterned so that the electrode does not exist in the vicinity of a light emitting end surface. Thereby, even when an Si film is formed on the light emitting end surface, the Si film is prevented from contacting with the light emitting end surface. In addition, after patterning the electrode, an insulating film (a silicon nitride film) is formed on the electrode for preventing the Si in the protective coating on the end surface from contacting with Au in the electrode, even when the Si film contacts with a surface of the electrode.
