Title: Work holding chuck for rotary table
Inventor: SHINKAWA HIDEJI
IPC: B23B31/177
Filed: 1986-04-10
Abstract: PURPOSE:To simplify holding operations and adjust the center position of works in irregular shapes accurately in a chuck for works, which are to be fitted on a rotary table of a vertical lathe etc., by performing simultaneous advance/ retraction of a plurality of pawls, manual advance/retraction of individual pieces and holding mutual location and thereby providing a construction capable of simultaneous advance/retraction. CONSTITUTION:A threaded rod 11 is mounted on each pawl seat 3 arranged slidably in the radial direction of a rotary table 1, wherein the rods correspond parallelly in the direction of sliding and rotated synchronously by transmissions 13, 14, 15 and ones 12, 16. A plurality of pawl seats 3 are advanced/retracted simultaneously through a flat gear 25 by rotation of the rods 11 and the pawl seats 3, i.e. gripping pawls 4, can be advanced/retracted individually by rotating a manual rotary shaft 31. If the position of individual gripping pawls 4 are once adjusted in accordance with the shape of the work, each gripping pawl 4 will thereafter advance/retract while the mutual positions are retained by simultaneously rotating the rods 11 with the driver device 14.

Title: Oil pressure oscillator
Inventor: NAGANO TOSHIMI
IPC: B06B1/18
Filed: 1982-05-19
Abstract: PURPOSE:To allow a reduction in length size by providing one or both of a fixed pressure chamber and an alternating pressure chamber in an oil pressure piston which is oscillated by means of pressure oil transferred and controlled by a spool. CONSTITUTION:When pressure oil is fed to a feed oil passage 35 through a connection port 33 from an oil pressure source, the pressure oil first enters the fixed pressure chamber 9 of a pilot valve 2 through a hole 9' and moves a spool 5 downward via an operation lever 7. The pressure oil also enters a fixed pressure chamber 23 through a feed oil port 15 and a communicating passage 27 and moves an oil pressure piston 4 upward. When a communicating passage 16 is communicated to the feed oil port 15 through a communicating chamber 20 during the upward movement of the piston 4, the pressure oil enters an alternating pressure chamber 10 through an oil passage 38 and moves the spool 5 downward. Then, the pressure oil is introduced into an alternating pressure chamber 24 through passages 11, 6, 12, 37, 22, 28 and moves the oil pressure piston 4 downward. By repeating the above operation, the oil pressure piston 4 is oscillated.

Filed: 1983-05-11
Abstract: PURPOSE:To prevent abnormality generated due to the backup operation of a CPU by forming a cicuit making a waiting system CPU track to a process value when the control output value of a main system CPU is different from that of the waiting system CPU. CONSTITUTION:A control output comparing program formed in addition to ordinary software checks the existence of a difference between an operation output from the main system CPU3 or 4 and an operation output arithmetic value operated at the waiting system CPU4 or 3. When the difference exists, the waiting system CPU4 or 3 outputs an alarm to the external, makes the self-memory contents track to a process value inputted from a process I/O unit 5 and bypasses the receiving data entry processing of a computer coupling device 9. When there is a difference between the outputs of the main and waiting CPUs, the abnormality generated due to the backup of the CPU can be prevented by making the waiting system CPU track to the process value.

Title: Current detecting circuit
Inventor: TERAMOTO AKIYOSHI
IPC: G01R15/14
Filed: 1979-07-02
Abstract: PURPOSE: To increase the detecting accuracy by flowing for detection an output ?current via a 1st resistance in which the diodes are connected in parallel plus the resistance having a smaller resistance value than the 1st resistance.  
     CONSTITUTION: The current in line 2 flows through resistance 6 owing to the barrier layer voltage V 7  of diode 7 in the region up to minute current I 1 , and is then detected from both ends of resistance 6 to be dilivered via amplifier 9, switch 8-2 and others. On the other hand, most in the current of line 2 flows via diode 7 in the region exceeding current I 1 , and thus the voltage at both ends of resistance 6 decreases. However, the voltage at both ends of resistance 3 is high enough and then delivered outside in the form of the current signal and via amplifier 4 and switch 8-1 each. Switches 8-1 and 8-2 are switched automatically in correspondence to current I 1 . Thus the current signals obtained through the 1st and 2nd resistances are delivered in the case of the minute current and other currents respectively. As a result, the detecting accuracy can be increased for the current.
