Title: Range finder
Inventor: ODA YASUO
IPC: G01C3/06
Filed: 1980-03-28
Abstract: PURPOSE:To make high-precision measurement possible to improve the steel piece yield, by constituting the range finder so that the condition that the projection angle for the object to be measured is constant is satisfied in scanning of the light beam. CONSTITUTION:Gas laser 2 is installed just above total reflective prism 1 which is arranged in the side of steel piece SP and is a reflective material. The laser beam generated from laser 2 is incident to the horizontal face of prism 1 perpendicularly and is reflected horizontally by the reflection surface and is projected to the opposite side face of steel piece SPO when the horizontal position of prism is changed by driving of step motor 5, the region of laser beam projection on the side face of steel piece SP is changed vertically. That is, the laser beam is scanned vertically on the side face of steel piece SP. Image sensor 4 is provided off to the upper position of condenser lens 3 to receive the reflection beam fromsteel piece SP. Step motor 5 is driven regularly, and the average distance to the side face of steel piece SP is obtained on a basis of data from sensor 4 and displacement meter 6 obtained during this regular driving.

Title: Semiconductor device and manufacture thereof
Inventor: IMAI SHINICHI
IPC: H01L21/316
Filed: 1993-03-02
Abstract: PURPOSE:To enable a thermal treatment carried out for flattening an insulating film to be lessened in temperature without deteriorating the insulating film in electrical properties by a method wherein auxiliary elements connected to main elements which form the matrix of the insulating film are substituted with non-crosslinked elements. CONSTITUTION:When a silicon oxide film is used as an insulating film, a network structural formula 1 is composed of silicon atoms which serve as the main elements and oxygen atoms which serve as the auxiliary elements. Oxygen atoms O as auxiliary elements in this matrix are substituted with non- crosslinked elements such as halogen atoms or fluorine atoms F of monovalence. By this setup, crosslink between Si-Si through the intermediary of O is cut off, whereby the insulating film is lessened in viscosity and flow temperature. For instance, when oxygen atoms O in a BPSG film are partially substituted with fluorine atoms F to turn the film into an FPSG film, and a flow temperature is decreased from 900 deg.C to 850 deg.C, so that an interlayer insulating film can be made to flow at a temperature at which a short channel effect is not produced in a semiconductor device.

IPC: G01N29/14
Filed: 1990-02-21
Abstract: PURPOSE:To shorten the time for an environmental test and to make the precise on-the-spot detection of a microscopic peeling breakdown by subjecting the signal past a band-pass frequency discriminator to analysis processing. CONSTITUTION:An acoustic emission sensor (AE sensor) 3 of a high-temp., high-pressure resistance and waterproof type is mounted to a test piece 2 installed in the test environment atmosphere 1a of an environmental tester 1. The AE signal detected by this AE sensor 3 is amplified by preamplifiers 4, 4 and is inputted via a band-pass filter 5 and the discriminator 6 to a personal computer AE analyzing apparatus 7. The discriminator 6 discriminates a noise and the AE signal. Further, a coincidence processing function is added to the apparatus 7 so that only the AE signal generated from the test piece 2 is taken out. The AE signal having high SN ratio is measured in this way by the noise cut based on the amplitude distribution by the discriminator 6, the frequency distribution by the filter 5 and the signal generating position distribution by the coincidence processing.
