Title: Tracking system of non-stationary communication satellite
Inventor: FUKUDA KIYOMITSU
IPC: H04B7/155
Filed: 1982-11-27
Abstract: PURPOSE:To perform always the satellite communication, by allowing one or more non-stationary communication satellites to exist always in the area where the satellite communication between earth stations is possible and providing two antennas in each earth station. CONSTITUTION:Earth stations 10 and 20 have two antennas 11 and 12 and antennas 12 and 22 respectively, and each earth station uses two antennas alternately to track non-stationary communication satellites. When a non-stationary communication satellite 1 exists in an area S where the communication between earth stations 10 and 20 is possible, antennas 11 and 21 track the communication satellite 1, and antennas 12 and 22 are not operated. When a non- stationary communication satellite 2 comes into the area S, antennas 12 and 22 acquire the communication satellite 2, and the communication satellite 2 is tracked by antennas 12 and 22 before the communication satellite 1 gets out of the area S. Consequently, two antennas are used alternately to track non-stationary satellites successively, and thus, the satellite communication is always performed.

Title: Growth of crystal thin film
Inventor: KUMOMI HIDEYA
IPC: H01L29/06
Filed: 1990-08-08
Abstract: PURPOSE:To make it possible to grow a crystal thin film comprising large particle-sized crystal grain groups by forming a single crystalline nucleus or a crystalline region comprising crystal grains at a specified position of an amorphous thin film, ion-implanting an element comprising an amorphous substance in other regions where the above region is excluded, carrying out heat treatment, growing the crystalline nucleus or crystal grains along the plane direction of the amorphous thin film, and crystallizing the amorphous thin film based on the solid phase growth. CONSTITUTION:In two planes of an amorphous thin film 2 on a base substrate 1, a nucleus formation region 3 is laid out cyclically so that it may be surrounded by a non-nucleus formation region 4 where a single crystalline nucleus 5 is arranged to grow selectively in the nucleus formation region 3. Then, they are adapted to grow up to the surrounding non-nucleus formation region 4. Then, ions are locally implanted into other regions excluding the region where the crystal grains have grown, thereby non-crystallizing a random crystalline nucleus which inhibits the growth of the crystalline grains 6. In succession, heat treatment is carried out so as to promote the growth. If necessary, when local ion implantation and heat treatment is repeated again, the crystalline grains 6 will face crystalline grains 6' which have grown from the adjacent nucleus formation region 3, and form a crystal particle field 9 in contact with the growth end face of the grains 6, and crystallize every Wigner-Seits - Cell 7, thereby finishing the growth.
