Title: Method for controlling medium thickness detecting mechanism
Inventor: OTANI KIYOSHI
IPC: G01B21/08
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling medium thickness detecting mechanism in which no high parts accuracy nor assembling accuracy is required, no much maintenance work is required, and the installed environment of the mechanism is not required to be maintained constantly. SOLUTION: At the time of initializing a mechanism for measuring thickness of medium, the average value of the thickness measured data of a standard medium is used as a reference value. At the time of operating the mechanism (ST10-ST16), the acceptance/nonacceptance of a medium is decided by comparing an average measured value calculated from the measured thickness data of the medium with a tolerance which is set based on the above-mentioned reference value as the measured thickness value of the medium. When the medium is discriminated as an acceptable, the reference value is corrected based on the average measured value of the medium through a correcting process (ST14).  At the time of correcting the reference value, the reference value is corrected so that the rate of contribution of the uncorrected reference value to the corrected reference value may become larger than that of the average measured value to the corrected reference value.

Title: Hetero junction type semiconductor device
Inventor: SHIGEKAWA NAOTERU
IPC: H01L31/108
Filed: 1992-06-10
Abstract: PURPOSE:To obtain a function as a hetero junction type semiconductor photodetector at a high speed by incorporating a valence band uppermost end at an energy position higher than a semiconductor well layer in a semiconductor barrier layer. CONSTITUTION:Electrons of electron.hole pairs generated in a semiconductor well layer 12 by irradiating a hetero junction type semiconductor photodetector with a light transit toward an anode layer 16 confined in the layer 12, arrive at the layer 16 and annihilates. However, the holes are confined in the layer 12, not transited toward the layer 12, but diffused in a semiconductor barrier layer 14, and immediately vanished by recombination on a surface of the layer 14. Thus, a time from an irradiation finishing time of the light to the photodetector to a time required for annihilate the holes is remarkably shorter than the time for ' the electrons and hence a function as the photodetector can be obtained at a high speed.

A generator motor 13 is turned and driven by the revolution of the pumped hydraulic turbine 5 at that time, and generated electricity is transmitted to an electric power company 18. Consequently, the outside is supplied with power at the same time as the salination of sea water, and sea water discharged from the pumped hydraulic turbine 5 is stored temporarily in an underground sea-water storage tank 7.  Sea water in the sea water storage tank 7 is pumped up into a water storage tank 9, and utilized for a salt-making industry, etc. Accordingly, since power obtained in the daytime is used for the electric power company and power pumped up is used at night, facilities having high economical efficiency can be prepared.
