Title: Evaluating method of abnormality occurring positions of revolving machines by acoustic signals
Inventor: SATOU MOTOHIRO
IPC: G01M99/00
Filed: 1978-06-14
Abstract: PURPOSE: To evalulate the abnormality-occurring range of a rotator by making an acoustic histogram by the acoustic signal from a suitable acoustic sensor out of acoustic sensors and revolution pulse signals.  
     CONSTITUTION: A revolution pulse generator and three or more acoustic sensors 24 thru 27 are installed to a revolving machine. Evaluation of the abnormality-occurring position on the stator 23 side is accomplished from the time differences of the acoustic signals and the time difference between the revolution pulse signal P from the revolution pulse generator and the acoustic signal arrived first out of the acoustic sensors is detected. Time compensation at which time delay becomes minimum for the range that can be covered by one acoustic sensor is accomplished to this time difference, whereby the evaluation of the abnormality-occurring position on the rotator 22 side is performed. Next, an acoustic histogram is made from the acoustic signal from a suitable acoustic sensor out of the acoustic sensors and the revolution pulse signal P. From this histogram, the abnormality-occurring range on the rotator side may be evaluated.

Title: Manufacture of photodetector
Inventor: DAIKU HIROSHI
IPC: H01L27/14
Filed: 1990-03-20
Abstract: PURPOSE:To enable high-density layout and to prevent crosstalks by selectively removing the insulating film and the crystal layer under it after a crystal layer of prescribed pattern is transformed selectively into element-forming compound semiconductor crystals to form photodetectors in them. CONSTITUTION:After an insulating film 8 is formed selectively on a CdTe crystal 2 deposited on a sapphire substrate 1, the region except the insulating film region is transformed into Hg1-xCdxTe crystal 6 by isothermal vapor phase growth with the insulating film 8 as the mask. After an electrode 9 is formed on this Hg1-xCdxTe crystal 6, the insulating film 8 and the CdTe crystal 2 under it are selectively removed. Therefore, the mask alignment of a resist film serving as a mask in forming the electrode 9 can be made with high precision as the substrate surface remains flat, so that devices can be formed easily with high precision. This design can provide multi-element photodiodes free of crosstalks even in high-density layout of elements on a crystal substrate.
