Patent JP-H0234028-A (JP)
Title: Radiant-ray proof mis type semiconductor integrated circuit device
Inventor: KOMATSU MICHIO
IPC: H03K19/003
Filed: 1988-07-25
Abstract: PURPOSE:To decrease an electric field applied to a gate oxide film of a MIS TR to <=1mV/cm and to reduce the fluctuation of the characteristic of a transistor(TR) after being exposed by a radiant-ray by arranging a 2nd MIS TR in series between the gate of a 1st MIS TR and an input terminal. CONSTITUTION:The same N-channel MIS TR is used for an input electric field limit TR 13 as an N-channel MIS TR 12 and a gate voltage +V is selected so that the electric field of a gate oxide film of the TR 12 is less than 1mV/cm. For example, when the thickness of the gate oxide film of the TR 12 is selected to be 300Angstrom , the gate voltage +VC is selected less than 3V+VT, e.g.,2.5V+VT where VT is a threshold voltage of the TR 13. The threshold voltage of the P-channel MIS TR 11 is about -0.5 to -1.0V, and that of the MIS TRs 12, 13 is about +0.5-1.0V. Thus, the fluctuation in the characteristic of TRs after being exposed is reduced.

IPC: G08B29/14
Filed: 1989-07-20
Abstract: PURPOSE: To make function test for a photoelectric sensor possible by incorporating a testing apparatus into a part of a photoelectric sensor circuit. CONSTITUTION: In a photoelectric sensor 13, the photoinadiation pattern of a main light source matches with the visual range of a photodetector, and the photodetector outputs an output signal which is in a first state if it detects light and in a second state if it does not detect light. Here, a test controller 11 is connected to the sensor 13 and generates on-test and off-test signals, and an LED is arranged in a vicinity of the photoelectric detecting element of the sensor 13. And at the time of on-test testing the LED is turned on only when a current is caused to flow in the main light source, and there is a fault if the output of the sensor does not show the detection of light at that time. And, at the time of an off-test, the main light source is prevented from carrying current, and there is a fault if the output of the sensor 13 shows the detection of light at this time.  In the controller 11, there is a failure output that indicates whether or not the sensor 13 has passed the on-test and the off-test, and besides an LED1 in a self test indicator 15 remains on while a fault continues.

Abstract: PROBLEM TO BE SOLVED: To assemble segments so that the cutters are not caught by the ground and the shield machine body is not retracted during the assembling work of the segments, in a driving controller for the shield jack of the shield excavating machine. SOLUTION: An electromagnetic proportional relief valve 5 is connected to the delivery pipe line 10A of a hydraulic pump 1. A conditional judge and operation processor 40 detects the number of shield jacks 4 selected by a selection switch 31 during the assembling work of the segments and computes such a control pressure that the gross shielding thrust by the stretching operation of the contracted shield jack 4 becomes smaller than the preset limit value of the gross thrust, on the basis of the detected data, and generates and outputs an instruction signal to regulate the relief pressure of the electromagnetic proportional relief valve 5 within the control pressure. The control part 41 of the electromagnetic proportional relief valve outputs a control signal corresponding to the instruction signal and sets the relief pressure of the electromagnetic proportional relief valve 5.
