Title: Obstacle locator
Inventor: TAKAGI TOSHIKAZU
IPC: G01S7/03
Filed: 1994-09-28
Abstract: PURPOSE: To protect the antenna housing against the pressure of earth and sand or water and to enhance the efficiency in the maintenance work of a dielectric resin plate by providing a joint, having a level difference, at the opening of a metal housing and coupling the dielectric resin plate. CONSTITUTION: A joint 20 having level difference parts 24, 25, is welded to the opening of a metal housing 10 and a dielectric resin plate 21 is fitted to the level difference part 24. Another dielectric resin plate 22 is coupled with an antenna housing 11 having a flange 26 disposed in the metal housing 10 and fitted to the level difference part 25. Since the level difference at the part 25 is larger than the total thickness of the flange 26 and the dielectric resin plate 22, a gap appears between the dielectric resin plates 21, 22 fitted to the joint 20. Consequently, the dielectric resin plate 22 can be protected even if the dielectric resin plate 21 is subjected to external pressure of earth and sand or water and pressed. Furthermore, the antenna housing 11 is provided with vibration resistance.

Title: Hydrogenation of polysilicon
Inventor: OKAMURA MASAMICHI
IPC: H01L21/336
Filed: 1994-10-25
Abstract: PURPOSE: To hydrogenate a polysilicon thin film transistor with high throughput by heat treating the polysilicon in an atmosphere containing hydrogen within a predetermined temperature range and then sustaining the heat treatment while lowering the temperature. CONSTITUTION: A gas 51 containing hydrogen is fed into a vessel 53 and polysilicon thin film transistors 56 mounted on a substrate supporting base 57 are heat treated by means of a substrate heater 58. Heat treatment is carried out at a temperature of 350-400 deg.C and then the heat treatment is continued while lowering the temperature down to 200 deg.C or below. Since hydrogen plasma is not employed, pressure reduced state is not required and since an atmosphere containing hydrogen is employed, hydrogen in the atmosphere has higher partial pressure as compared with plasma hydrogenation. Consequently, hydrogen can be diffused quickly into the polysilicon thin film as compared with plasma hydrogenation and the hydrogenation time can be shortened.  Furthermore, since a system for generating hydrogen plasma under reduced pressure is not required, a large number of substrates can be treated simultaneously.
