Filed: 1986-04-12
Abstract: PURPOSE:To aim at improvement in polishing efficiency, by having an abrasive member vibrated or rotatively moved within one flat surface, while vibrating it in a direction being crossed with the moving direction. CONSTITUTION:A casing 11 with a built-in air motor 10 is hangingly supported on the lower end of a hone 9 of an ultrasonic vibration generator system 3. At the lower side of this casing 11, there is provided with a support member 12 to be reciprocatively vibrated with a horizontal plate by operation of the air motor 10, and an abrasive member 13 is clamped to the lower end. With extension of a piston rod 4, the abrasive member 13 is forcedly pressed to the lower part of a metal mold with the specified pressure via the ultrasonic vibration generator system 3. And, the air motor 10 is operated and the abrasive member 13 is reciprocatively vibrated within the holizontal plate, thus a metal mold F is polished. Under this state, if the ultrasonic vibration generator system 3 is operated, vertical ultrasonic vibrations are generated from the hone 9, whereby the abrasive member 13 is vibrated up and down. With this beating action, erosion to the metal mold F is speeded up and simultaneously chips or swarf between the metal mold F and the abrasive member 13 are discharged out, thus polishing efficiency is improved.

Title: Buffer control system
Inventor: FUJIMURA NORIAKI
IPC: G06F5/14
Filed: 1979-07-06
Abstract: PURPOSE:To prevent both the underflow and the overflow by setting some of plural numbers of monitor buffers under the data full state and then setting other monitor buffers under the data vacant state each, thus ensuring the proper control for the buffer. CONSTITUTION:Data buffers 311 and 312 are set under the data vacant state; while data buffers 313 and 314 are set under the data full state respectively. And the memory state is monitored for each of buffers 311-314 by data buffers 321-324.  Then transmitting data signal SD1 is written into buffer 311 with the fall of transmitting timing signal ST1, and at the same time buffer 321 is set under the data full  state by the output of fall detecting circuit 33. Then the contents of buffer 311 is  transferred to buffer 312 by clock CLK and via gates G1 and G4 owing to the fact  that buffer 322 is under the data vacant state. Thus buffer 322 is set under the data  vacant state. But the contents of buffer 312 is maintained there since buffer 313 is  under the data full state. As a result, both the underflow and the overflow can be  prevented, thus ensuring the proper control of the buffer.
