Title: Preparation of single crystal
Inventor: SHIMADA TAKASHI
IPC: H01L21/208
Filed: 1985-04-23
Abstract: PURPOSE:To obtain a single crystal having high quality with almost uniform concentration of impurity in the direction along a longitudinal axis by pulling a single crystal from melt of the starting material contg. an impurity, reducing the pulling speed in accordance with increase of percentage of solidification. CONSTITUTION:GaAs polycrystal, In as impurity, and B2O3 as sealing material, etc., are charged to a bottomed cylindrical quartz crucible 1 opened at the top and provided freely revolvably by supporting the external periphery on a supporting bed 2 of the crucible which is fixedly attached to a revolvable shaft 3. The content of the crucible is melted by heating at ca. 1,240 deg.C with a graphite heater 5. The surface of the melt 4 of the starting material is covered with a sealing material 10 and, at the same time, the inside of a pressure vessel 8 housing the crucible is held at high pressure with inert gas such as Ar. Then, a seed crystal 6 is dipped in the surface of the melt 4 of the starting material and the seed crystal 6 and the crucible 1 side are revolved in opposite direction to each other with a pulling shaft 7 for revolution and vertically movable pulling shaft 7 to pull the seed crystal 6 and to grow the single crystal 9 gradually. Further, the pulling speed is continuously reduced gradually in accordance with the increase of the percentage of solidification reducing the segregation coefft. and a single crystal 9 is thus pulled up.

Title: Ultrasonic sensor
Inventor: AZUMA NAOYA
IPC: G01S15/87
Filed: 1986-04-14
Abstract: PURPOSE:To prevent incorrect information due to changes in environmental conditions and the like by providing a first detection means for detecting the presence of an object to be detected in a detecting area and a second detection means for continually detecting the object to be detected in an area larger the detecting area. CONSTITUTION:A receiving unit 112 is provided as a second detection means in addition to a receiving unit 111 as first detection unit. By making the amplification factor of the amplifier circuit 52 in the receiving unit 112 larger than that of an amplifier circuit 51, the width of a detecting area is enlarged. Further, by making a time during which the gate of a signal processing circuit 72 is opened longer than a time during which the gate of a signal processing circuit 71 is opened, the range of the detecting area in the direction of a distance is enlarged. Accordingly, since the distribution between both areas is facilitated by continually detecting the enlarged area of the receiving unit 112, incorrect information due to changes in various environmental conditions is prevented.
