Title: Optical coupling device
Inventor: SAKATA FUSAKO
IPC: H01S5/00
Filed: 1985-02-13
Abstract: PURPOSE:To enable fixture with high junction efficiency by a method wherein a resin introduced groove, which can flow excessive resin, is formed to a bottom part of a concave section formed on a compound semiconductor substrate. CONSTITUTION:An activator region 3, which is extended to [110] face direction, is formed with regard to [100] face of an InP substrate and a window 7 is made after masking an SiO2 film e.g. on the whole face, then an (a) section of the window 7 becomes a V-groove guide 4 after etching thereof and (b) section becomes a resin introduced groove 5. When H3PO4/HCl system etching is performed for the substrate crystal, the V-groove appears finely on the V- groove guide, then the groove 5 is formed to the groove introduced section due to crystal orientation dependability of etching. In the groove depth, the resin introduced groove 5 side is trimmed to be about several mum deeper than the V groove 4 side. When the optical fiber is fixed on the V-groove guide, optical output, which the optical fiber accepts from laser active region, is almost the same value as that before introducing resin. Thereby, loss before and after fixing of the optical fiber is made zero, therefore high efficient junction can be performed in that respect and it becomes a stable optical coupling device.

Title: Solar power generating apparatus
Inventor: TANI TATSUO
IPC: E06B7/086
Filed: 1984-02-13
Abstract: PURPOSE:To improve incident efficiency, to improve time performance and to lower wind-pressure load, by arranging a plurality of stripe shaped photoelectric conversion panels in parallel, turning the panels in a linked mode, and tracking the sun light. CONSTITUTION:A plurality of stripe shaped photoelectric conversion panels are arranged in parallel and turned by tracking and driving shafts 8 in a linked mode. The tracking and driving shafts 8 are rotated by a tracking linked rod 5 in a linked mode. When the light receiving surface of the panel 1 is in an evacuated state, the light receiving surface 1a faces downward. When the light receiving surface is tracking incident sun light 16, the surface 1a faces upward. By using a structure, in which the panel width is made small and a specified interval is provided in a plane, wind pressure can be reduced to a large extent. Since the sun light is tracked by the rotation, the amount of the incident light is increased.

Title: Information transmission device
Inventor: MUTSUSHIMA SHIYOUJI
IPC: H04B7/26
Filed: 1978-03-06
Abstract: PURPOSE:To ensure the transmission of the information for the sensor on the road with the mobile object in the fixed direction by locating the bar antennas of the mobile object and the sensor with the 45-degree angle to the vertical direction so that the upper side of the antenna may turn the outside of the road each. CONSTITUTION:The 45-degree angle is given to bar antennas 3 provided to both mobile object 1 and sensor 2 on the road against the vertical direction and so that the upper side of antenna 3 may turn the outside of the road each. For instance,  antenna 3-1b of mobile object 1-1 and antenna 3-1a of sensor 2-1 on the road to  transmit the information are turned to the same direction within the vertical plane.  But the antenna direction cross each other with antenna 2-2a of sensor 2-2 on the  road at the side where no information of the opposite side should be transmitted.  Thus, the information of only the necessary direction is transmitted. As a result,  sensor 2 identifies the tranvelling direction of the mobile object and thus can perform the information transmission with the mobile object in the fixed direction.
