Abstract: PURPOSE:To obtain stable laser outputs by a method wherein the time relation between the photo emission start timing of an excitation light source and the laser oscillation timing of a Q switch laser oscillator arranged at the front step is controlled with thre variation in temperature of a laser amplification element. CONSTITUTION:A posistor 11 is connected in close contact with a rubby rod 6 so as to turn the variation in resistance with its temperature into the variation in value of the time constant CR of the monostable multivibrator of a time delay circuit 7. Since the resistance value of the posistor 11 has positive characteristics with respect to temperature, the resistance R increases when the temperature of the rubby rod 6 rises in direct contact of the posistor with the resistor R of CR time constant, and the trigger P4 of the time delay circuit 7 turns into a trigger pulse P4' by a delay of td1 with the increase in time constant, an excited liquid P5 into P5', and a laser amplification gain P7 into P7'. At the point of passing through the rubby rod 6, a giant pulse P3 from the Q switch oscillator 4 comes into agreement with the laser oscillator gain P6 generating before its temperature rise, and then a giant pulse P8 after amplification can be obtained.

Abstract: PROBLEM TO BE SOLVED: To equalize thrust force of a shield jack by placing extension sides of the shield jack and contraction sides in a communication state, and blocking outflow of working fluid for the outside from the fluid pressure circuit of the extension side. SOLUTION: A jack selection valve 2 is provided in response to each shield jack 1, and a pressure sensor 3 is provided in a pipe passage between an extension side 1a and the selection valve 2. When pipe jacking is performed, it is judged by the sensor 3 whether the pressure of the extension side of the jack 1 is first set pressure or more. When it is detected that it is the set pressure or more, investigation is performed on the whole remaining jack 1. The whole jack 1 of the set pressure or more is selected and the selection valve 2 is opened. Thereby the extension sides of the opened jack 1 of the selection valve 2 communicate with each other.  High pressure does not act on the circuit of a valve 18 connected to the contraction side circuit of the jack 1, the valve 18 is not opened, and oil flowing in the direction of a valve 7 from the extension side circuit of the jack 1 does not occur. Thereby increase of thrust force of the partial jack can be prevented.
