Filed: 1993-03-04
Abstract: PURPOSE:To enable working of a prepared hole and tapping by one working process by forming a blade edge for working the prepared hole for tapping at the tip of a punching die and successively providing a tap part for tapping. CONSTITUTION:The punching die 57 is composed of the blade 65 and the tap part 67. The prepared hole is worked on the work W with the blade 65 by lowering the die 57. Further, a screw is formed on the surface of the worked prepared hole with the tap part 67 by lowering the die 57 while rotating it. When the screw is formed, the die is lifted while rotating it reversely and working is completed by drawing the die 57 out of the work W. In this way, working is not executed separately in respective processes but working is executed at one time, so the process is reduced to half and workability is improved.

Abstract: PURPOSE:To prevent occurrence of a non-brake condition by making methods of setting a pseudo-vehicle speed upon brake operation and upon non-brake operation different from each other so as to inhibit the pseudo-vehicle speed from shifting away from an actual vehicle speed in association with the racing of wheels before anti-lock control being started. CONSTITUTION:Upon brake operation a high select circuit 14 in a pseudo-speed vehicle speed computing circuit 13 selects a maximum wheel speed VmH among four wheel speeds Vw1 to Vw4 which are obtained by computing circuits 5 to 8, and sets the maximum wheel speed as a pseudo-vehicle speed Vv. Further, the maximum wheel speed VmH becomes lower than the pseudo-vehicle speed Vv, a decay valve DV is controlled so as to start the reduction of the brake hydraulic pressure. In such a control process, a low select circuit 21 selects a minimum wheel speed VwL among the four wheel speeds upon non-brake operation. A speed at which an acceleration side followable limit corresponding to this minimum wheel speed VwL is turned into an acceleration value which is less than an acceleration side followable limit of the pseudo-vehicle speed Vv upon brake operation, is set as the pseudo-vehicle speed Vv.
