Abstract: PROBLEM TO BE SOLVED: To exactly control compensation of an input leak current by regulating a current to be the control source of a constant current circuit for applying the emitter current of a transistor while changing the value of a resistor connected between the emitter of the transistor constituting a current mirror circuit and a prescribed power source. SOLUTION: The average value or maximum value of the input leak current is calculated from current values measured by respective impressed voltages. The control value of the input leak current is determined in order to settle within the range of allowable values of the input leak current specified by the design specification of a semiconductor integrated circuit, and the control value of an emitter resistor R03 of a current mirror circuit 9 required for control is determined. Then, the emitter resistor R03 of the input leak current compensating circuit 1 of the semiconductor integrated circuit is worked into prescribed control value by a resistor working device. In such a case, working is performed while measuring a current at all the time for exact control into control value to be found.

Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To generate a sufficient resilient force from a fixing member having small volume by moving a piston such that the fixing member is opened by means of compressed gas and pressure fluid. SOLUTION: The body 1 of tool or sonde is lowered down into a longitudinal hole 2. It is pressed firmly against the wall as an anchor arm (fixing member) 4 turns and released therefrom through reverse motion. Motion of the arm 4 is controlled by the movement of a link 5 in a cylinder 6. More specifically, compressed gas in a chamber 7b pushes a piston 8 backward to compress the liquid in a chamber 7a. Pressure of gas is transmitted on the liquid in the cylinder 6 to move the link 5 which then opens the arm 4 until it is fixed to the wall of the longitudinal hole 2. When the operation proceeding at that stopping depth is finished and a transition is made to other depth, power supply to a motor 14 is controlled to compress the liquid being fed through a pump 13 thus retracting the piston 8 toward a stop part 19.
