Title: Preparation of semiconductor device
Inventor: KURODA HIROSHI
IPC: H01L21/3213
Filed: 1982-03-09
Abstract: PURPOSE:To improve manufacturing yield and reliability by leaving a conductive film, on the occasion of etching a conductive film formed on a semiconductor substrate, through the etching thereof in such a depth not reaching an insulating layer thereunder and by converting the remaining conductive layer into an insulating film through the anode oxidation. CONSTITUTION:A thin SiO2 film 22 and an Al film 23 are sequentially formed on a semiconductor substrate 21. A resist pattern 24 is then formed on the Al film 23. Thereafter, the etching is carried out to the film 23 in such a depth as not reaching the film 22 by the dry etching method. Then, the remaining film 23 is anode-oxidized and converted to an insulating film (Al2O3) 25 with the photo resist pattern 24 used directly as the mask. Since the film 23 is not totally etched and the remaining film 23 is converted into the insulating film 25, a problem of short-circuiting in wiring by the over etching of film 22 and the Al film remaining at a side can be solved.

Title: Grindstone piece and grindstone head for vertical shaft round table type surface grinder
Inventor: GOTOU TOMOAKI
IPC: B24D7/06
Filed: 1979-03-30
Abstract: PURPOSE: To reduce the grinding resistance of grindstone pieces and thereby improve the grinding efficiency, by forming a hollow space in the inner portion of the grindstone pieces so as to stay a part of chips therein.  
     CONSTITUTION: A contour line 5 of a grinding surface 8 of a grindstone piece 4 is similar to that of an equilateral triangle, which grindstone piece 4 has no vertical angle portion and no base angle portions. A hollow space 7 having a contour line 6 similar to the contour line 5 is formed in the inner portion of the grindstone piece 4 to allow a part of chips of a work, which occur during a grinding operation with the grinding surface 8, to escape and stay in the hollow space 7. This permits preventing chips from being accumulated in the central portion of the grinding surface 8, so that the generation of a resistance in the central portion of the grinding surface 8 can be prevented. Thus, the grinding resistance can be reduced and the grinding efficiency can be improved.

Title: Abnormality detection system
Inventor: FUJIKURA NOBUYUKI
IPC: H04L12/437
Filed: 1981-03-18
Abstract: PURPOSE:To orientate the position of a station, where a fault occurs, in a monitor station, by causing stations, which cannot receive alarm erasing data, to add their own addresses to alarm continuing data and transmit this data onto a loop. CONSTITUTION:If a transmission device N4 becomes faulty, data transmitted from processing devices H1-Hn disappear in the transmission device N4. Consequently, transmission devices except the device N4 output alarm data to respective processing devices. Meanwhile, the processing device H1 which monitors conditions of the whole of the system transmits alarm erasing data onto a loop transmission line L through a transmission device N1 when receiving alarm data. Processing devices which receive alarm erasing data stop the alarm output, and processing devices H5, H6- which do not receive alarm erasing data for a prescribed time add their own addresses to alarm continuing data and transmit this data onto the loop. On a basis of these address values, the processing device H1 discriminates that the processing device N4 is faulty.

Abstract: PURPOSE:To make possible the separate observation of symmetrical and non- symmetrical components of the aberration of the lens to be inspected by disposing a semispherical lens having the radius of curvature at the focal point of the lens. CONSTITUTION:When observing the symmetrical components of the aberration, that is, when desired to see the interference stripes of waves (a) and (b), the semispherical lens 3 is shifted in a direction perpendicular to the optical axis. The reflected light or wave (c) from a spherical surface 3'' is condensed at a position offset from the center on a spatial filter surface 8. This rays of light are cut so that only the symmetrical aberration of the lens to be inspected is observed. When observing non-symmetrical aberration components, that is, when it is desired to see the interference stripes of the waves (b) and (c), a plane surface primary standard 1 is tilted slightly. At this time, the reflected light or a wave (a) from the standard 1 is cut by the spatial filter 8 so that only the non-symmetrical aberration of the lens to be inspected is observed. When observing the overall aberration, that is, when it is desired to see the interference stripes of the waves (a) and (c), the standard 1 and the lens 3 are inclined by the same angle and the spatial filter 8 is moved therewith so that only the wave (b) is cut by the filter 8 so as to permit the observation of the overall aberration.
