IPC: H01L31/0232
Filed: 1981-12-18
Abstract: PURPOSE:To provide a firm adhesive photo sensor which is capable of dot-illuminating an original with a high illuminance, by method wherein a reflected light detecting mechanism is located around a through-hole in one main surface of a substrate which has the through-hole in the other main surface that is open to a light source and has an approximately V-shaped section. CONSTITUTION:A first V-groove 14 and a second V-groove 15 are formed in (100) surface silicone substrate 11 by an anisotropic etching. An incident light 13 not only passes through directly an opening A' which measures, for example, 100mum in width and is provided in the V-groove 14, but some of it passes  through the opening A' in a condition to be multireflected by the slope of the V- groove 14, which enables to perform a high-illuminance dot-illumination on an illuminating point 17 on an original 12 surface. Light, focused to the illuminating point 17, is multireflected by the V-grooves 15 and 15' to be guided to a collecting element 18.

IPC: H01L21/66
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent dewing on the back of a socket from generating in low price construction by heating a wiring board arranged outside the opening part of a chamber by heat-transfer from a heating board fitted to the circumference of the chamber opening part. SOLUTION: A socket adapter 98 is connected with the back of a socket 20 (outside a chamber 6) held with a socket guide 82, and the terminal of the socket 20 and a wiring board 100 arranged outside a chamber opening part 92 are electrically connected together through the adapter 98. A heating board 106 is fitted to the circumference of the chamber opening part 92, and the wiring board 100 is heated by heat transfer through a wiring board presser ring 114. Hereby, even when the inside of the chamber 6 is cooled under ordinary temperature, because the wiring board 100 is heated at temperature over the dew point of the atmospheric gas, dewing on the wiring board 100 and a test head 10 is prevented from generating. Further, because the electric route between the socket 20 and the wiring board 100 can be shortened, generation of noise is restrained, and reliability of the test is improved.

IPC: C22C38/16
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To provide a water resistant long-life rolling bearing whose life is long even under an environment where water mixes into a lubricant.

Title: Digital relay
Inventor: FUKUMURA MASAKI
IPC: H02H3/02
Filed: 1994-08-30
Abstract: PURPOSE: To make the software processing unnecessary for sampling number creation and transfer by generating a reset signal for one round sampling period from a data collecting module and by internally creating sampling No. by using reset signal as initializing timing signal by analog input module. CONSTITUTION: In sampling of analog input signal, the signal is taken in analog input modules 1 and 2 in a constant period. A reset signal is sent from a data collection module 4 to the analog input modules 1 and 2, processing of sampling No. is set to zero (initialize), and thereafter count processing for the sequential increment of the sampling Nos. is performed in conformity with the sampling synchronizing signal. Analog input modules 1 and 2 transfer the sampling Nos. by count to the data collection module 4 in addition to the digital data. By doing this, the data collection module 4 does not require the software processing for sampling No. creation and transfer.
