Title: Control method of automatic bolt tightening device
Inventor: OZAWA HAJIME
IPC: E21D11/40
Filed: 1991-10-24
Abstract: PURPOSE:To eliminate interference generated when the tightening is completed, and enable secure detachment of holding arms from bolts and nuts without upsizing the device itself in a bolt automatic tightening device to be employed in a segment assembling operation within a tunnel. CONSTITUTION:After the tightening is completed, an arm-moving means is controlled so that the evacuating action may be implemented intermittently from at least either of the tightening position of bolt-holding arms and nut- holding arms. In this case, it is much more effective if the arm-moving means is controlled so that the advancing action may be added during the stopping time of the evacuating action. It is also effective to control the tightening part moving means so that fine vibration may be given to the whole tightening part in the direction normal to the axial line of the bolts in addition to the evacuation of the bolt-holding arms and the nut-holding arms.

Title: Semiconductor memory
Inventor: OKU SATORU
IPC: G11C11/413
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To enable shortening a standby time from stop of operation of a sense amplifier to recovery by providing a first input means inputting a first control signal stopping operation of a sense amplifier and a second input means inputting a second control signal stopping operation of a reference voltage generating circuit. SOLUTION: A first control signal HALT is inputted to sense amplifiers 51 -5n respectively, a second control signal STANBY is inputted to a reference voltage generating circuit 6, and they can be controlled independently. When read-out operation is restarted, only the sense amplifier is stopped by the first control signal HALT. In this case, as the reference voltage generating circuit 6 is operated, operation can be started sooner. When current consumption is desired to suppress, a current can be largely reduced by stopping the sense amplifiers and the reference voltage generating circuit 6 by two signals of the first control signal HALT and the second control signal STANBY.
