Title: Control device for shield machine
Inventor: YAGISHITA NAGAMITSU
IPC: E21D9/093
Filed: 1992-03-09
Abstract: PURPOSE:To obtain a required construction curvature by installing an articulation angle revision control means which operates an articulation mechanism until the articulation angle has reached a revised indication value based on an articulation angle revision indicated value of an articulation angle revision indicating means and a measured value of an articulated state. CONSTITUTION:An articulation controller 25 selects and drives articulation operation valves 22 and 23 by way of a sequencer 26 based on an instruction from an outside control device. Based on articulation angle indicated values previously input and measured data of an articulation stroke sensor 27 and a pressure sensor 28, the controller 25 selectively drives articulation jacks (9-1) to (9-4) and (9-5) to (9-8) out of each group on both sides until the control variables of the variation angle reach an indicated value or the operational hydraulic pressure rises dramatically within the indicated value. When the articulation angle is changed during construction work, the control device transmits an articulation angle revision indicated value to the controller 25. The controller 25 selectively drives the jacks (9-1) to (9-8) until the control variable of the articulation angle reaches the revision indicated value.

Title: Combustor
Inventor: OTOMO ICHIRO
IPC: F23N1/02
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To realize more appropriate extinguishing by an arrangement wherein fuel supply to a fuel regulating means is not interrupted immediately but reduced gradually when combustion is interrupted. SOLUTION: Output phase timing at the output port of a control section is controlled from a fan motor to decrease air supply slightly earlier (S1). Upon elapsing a specified time (S2), output phase timing at the output port of the control section is controlled to decrease the capacity of a solenoid pump gradually (S3). After decreasing the capacity gradually for a short time (S4), output at the output port of the control section is controlled to stop the solenoid pump (S5) and post-purge operation is performed by rotating only the fan motor for a specified time (S6). Consequently, combustion gas in the combustion chamber is exhausted and the inner temperature thereof is lowered before stopping the fan motor (S7) and ending soft extinguishing operation.  Soft extinguishing can be realized by decreasing fuel gradually for a specified time after starting extinguishments and then interrupting fuel supply immediately.
