Abstract: PURPOSE:To make a bed so as not to be deformed as well as to make such electro-discharge machining as excellent in accuracy performable, by installing each supporting device, supporting the bed, in center positions of a mounted work, a saddle, etc., beneath the machine bed. CONSTITUTION:An actuator 11 detects a center-of-gravity X-Y plane surface of the total weight of a bed 1, a saddle 4, a table 6 and a work 7 and is set up beneath a machine bed 1, having an arm 13 which comes into contact with a lower surface of the bed 1 and smoothly slides on a base 12, shiftable to the center-of- gravity position. And, each of support blocks 14a-14d is set up with a slight clearance delta with the lower surface of the bed in the upper end, and locked to the base 12. Thus, the arm 13 is automatically shifted to a spot just under the center-of-gravity position of the total weight of the bed 1, the saddle 4, the table 6 and the work 7, supporting the total weight. Therefore, maintenance of the squareness between the bed 1 and a column 2 is improved and, what is more, it is no longer required to improve rigidity for a part along a guide rail 3 of the bed 1 with a reinforcing rib.

Title: Frame step-out detecting system
Inventor: YOSHIDA ATSUSHI
IPC: H04L7/00
Filed: 1987-03-24
Abstract: PURPOSE:To surely detect frame step out without increasing transmission speed, by applying a vioration operation on a transmission data. CONSTITUTION:When the phases of frame synchronizing pulses WT and WR in transmission/reception, with those of pseudo random number generators 4 and 10 in the transmission/reception coincide, it is resulted that an encoding signal Y0 equals Q0, and no errors except one on a transmission line 8 are generated. If the step out is generated, it is resulting that the encoding signal Y0 does not equal Q0, then the error is generated, and so that the error is much larger, and continues, than the error generated on the transmission line 8, it is possible to detect it by a detector 15, Therefore, it is possible to surely detect the frame step out by allowing to coincide the phases of the frame synchronizing pulses WT and WR, with those of the pseudo random number generators 4 and 10 in he transmission/reception, at time of initialization, and taking synchronization again in case of detecting a large and continuous error by the detector 15.

Filed: 1989-03-20
Abstract: PURPOSE:To concentrate machining points of a punch for a pressed work at one point and precisely machine it by providing sticking means closely sticking the pressed work along the receiving section of a die. CONSTITUTION:When a pressed work 12 is closely stuck along a receiving section 13 formed with the curved surface of a die 11 by sticking means (guide rollers) 19 and 20, tensile stress is generated on the surface side of the pressed work 12 on the receiving section 13 of the die 11, and compression stress is generated on the rear side. As a result, machining points of a punch 1 for the pressed work 12 are concentrated at one point, and precise machining can be performed. When the punch 1 is pulled out, the pressed work 12 is closely stuck to the receiving section 13 formed with the curved surface of the die 11, thus it is not separated from the die 11, the occurrence of burrs and the breakage of the punch 1 caused by the pulling out can be prevented, and the punch 1 can be easily pulled out.

Abstract: PURPOSE:To hold secondary pressure as set by supplying the secondary pressure to the diaphragm chamber of a pressure control valve, and admitting pressure which is adjusted by a control valve to a bellows phragm chamber, and controlling the pressure in the bellows phragm chamber stably. CONSTITUTION:The secondary pressure P2 from downstream-side piping is admitted to the diaphragm chamber 10 through branch piping (2nd conduit) 13. The control valve 3 reduces the primary pressure P1 from the branch piping 14 to specific pressure set by a spring 17 through a valve body 20 and supplies the controlled pressure Ps to the bellows phragm chamber 11a through a communication pipe 15. Namely, the pressure control valve 2 has its valve opening extent adjusted according to the secondary pressure P2 supplied to the diaphragm chamber 10a and the control pressure Ps supplied to the bellows phragm chamber 11 to control the primary pressure P1 so that the secondary pressure P2 in the downstream piping 6 is the set pressure. Consequently, the pressure control valve 2 controls the secondary pressure P2 to the specific set pressure almost without being affected by variation in the primary pressure P1.
