Title: Photo trigger thyristor
Inventor: NIWAYAMA KAZUHIKO
IPC: H01L31/111
Filed: 1982-06-19
Abstract: PURPOSE:To obtain the photo trigger thyristor having the required photo trigger by a method wherein a thickly formed NE layer is thinned off by performing an etching. CONSTITUTION:The NE layer of light-receiving part is formed simultaneoulsy with the NE layer of an ordinary thyristor under the same condition. In regard to the distribution diagram for impurity density, the abscissa (x) indicates the depth from the wafer surface, (a) region indicates NE layer 4, and (b) region indicates PE layer 3. The ordinate (y) indicates the impurity density in logarithmic scale. After the diffusion as indicated in the diagram has been performed, the light-irradiated part 8 on the NE layer is thinned off by performing an etching. As indicated in the diagram, the impurity density of the NE layer 4 on the light-irradiated part 8, which is left by etching, is reduced and the sheet resistance PS is increased. Accordingly, the NE layer suitable for the phot trigger thyristor can be formed by properly controlling the amount of etching. As the thickness of the NE layer on the light-receiving part is formed in 5-10mum in thickness without having a special process and the sheet resistance is set at 50OMEGA or above, an excellent photo trigger characteristics can be obtained.

Title: Treatment of base material for optical glass
Inventor: YANO SHINICHI
IPC: C03B37/018
Filed: 1984-05-25
Abstract: PURPOSE:To obtain a base material for optical glass having high dimensional accuracy and enabling the easy calculation of the ratio in outside diameter by heat treating a porous glass layer around a rodlike base material after supporting both ends of the base material. CONSTITUTION:The upper and lower ends of a rodlike quartz base material 1 having a porous quartz glass layer 2 around it are attached to support members 7a, 7b, and the base material 1 is slowly moved into the core pipe 4 of a heating furnace 3 while rotating the members 7a, 7b. The porous glass layer 2 is converted into a glass layer 2' by sintering, vitrification or other method. Since the expansion and contraction of the rodlike base material 1 in the longitudinal direction are hindered by the supported ends, the length L1 of the base material 1 before the treatment is equal to the length L2 of the base material 1 after the treatment, and the size of the treated base material consisting of the rodlike base material 1 and the glass layer 2' in the diametral direction is made accurately uniform, giving optical glass of high quality. The diameter of the rodlike base material 1 is known and is not changed, and the diameter of the glass layer 2' can be easily measured by a conventional means, so the ratio in outside diameter between the base material 1 and the glass layer 2' is calculated without requiring the trouble-some measurement of the refractive index distribution.

Title: Torque variation absorbing damper
Inventor: OGISHIMA KOICHI
IPC: F16F15/12
Filed: 1995-04-07
Abstract: PURPOSE: To realize a whirl-stop action even without a whirl-stop pin thereby reduce the number of a part item while having a function same as in a case wherein the stop pin is provided, by providing a recessed part, wherein a bearing is fitted to be engaged in a diameter direction, on the inner peripheral surface of a pulley. CONSTITUTION: In a torque variation absorbing damper, since a resin-made bearing 5 is fitted to be engaged in a diameter direction with a recessed part 5c provided on the inner peripheral surface of a pulley 5, the whirl-stop between the pulley 5 and the bearing 9 is performed. Consequently, a whirl-stop action can be made without a whirl-stop pin. Also when the resin-made bearing 9 is thermally expanded, resin 9a is increasingly entered into the recessed part to absorb an expanded part by a certain degree. Consequently, the excessive increase of slide resistance can be eliminated at the time of the thermal expansion of the bearing 9, thereby preventing the hindrance to a necessary slide rotation.

Abstract: PURPOSE:To make it possible to simultaneously measure a short-term exposed dose and a long-term accumulated exposed term, by inputting an accumulated dose value to an operator to calculate the difference of the accumulated exposed dose and the accumulated dose value. CONSTITUTION:Fluorescence (b) is allowed to generate from an exposure element 2 by the excitation of ultraviolet rays (a) and supplied to a photoelectric converter 3 to be converted to an electric signal which is, in turn, supplied to an operator 4 to obtain an accumulated exposed does (c). On the other hand, the accumulated dose value (d) mueaured at the previous measuring time is read from a data memory element 7 by a data reading writing apparatus 8 to be inputted to the operator 4 and the lately short-term exposed dose (e) can be obtained from the difference of the accumulated exposed dose (c) and the accumulate dose value (d). In this case, the accumulated dose value (d) corresponding to the accumulated exposed dose (c) is re-written in the data memory element 7. By using this mechanism in personal radiation exposure control or environmental radiation exposure control, both of a short-term exposed dose and a long-term accumulated exposed dose can be simply known within a short time by one measuring element.
