Title: Isolation type digital input circuit
Inventor: TAKEGAKI TADAYUKI
IPC: H03K17/78
Filed: 1987-12-28
Abstract: PURPOSE:To prevent malfunction of a computer by providing a sensor having a common emitter open collector output, a pulse generating section driving a pulse transformer and a photocoupler extracting a sensor output state. CONSTITUTION:When a pulse signal is inputted to a base of a transistor(TR) Q1 from a pulse generating section 18, the TR Q1 repeats on/off. Thus, a pulse current as shown in figure (A) flows to the primary winding of a pulse transformer (Pt)PT. Thus, a pulse voltage as shown in figure (B) is induced at the secondary side of the (Pt)PT. When the TR Q is turned on, since a current flows to a photocoupler (Pc) 14, a signal is obtained from the output of the Pc14. When the TR Q is turned off, since no current flows to the Pc14, no internal processing input signal is obtained from the output of the Pc14. Thus, only when the TR Q is turned on, a current flows to the Pc14. Since the sensor state is extracted by using the Pc only when the TR is turned on in this way, the superimposition of the noise on the computer from the sensor is prevented.

Title: Balancing device for main spindle of machine tool
Inventor: ARIYOSHI YUKIHIKO
IPC: B23B19/02
Filed: 1990-11-30
Abstract: PURPOSE:To reduce size and to prevent protrusion of a balancer to the outside of a slide due to centrifugal force during operation by pivotally mounting the intermediate part of a primary balancer, having a weight secured to the tip of a support lever, on a rotary bed and slidably coupling the base end of the support lever to the longitudinal groove of the slide. CONSTITUTION:Through rightward movement of a pin 17, engaged with a groove 24 in the back of a slide 7, when a slide 7 is moved rightward, a weight 16 part at the tip of a primary balancer A is revolved in a leftward direction opposite to movement of the slide 7, and a balance on a rotary bed is mostly maintained. Since the moving locus of the primary balancer A is arcuate, the balancer is prevented from long protrusion like a conventional type. When, with this state, a main spindle 1 is rotated at a high speed, the weight 16 of the primary balancer A is about to return toward a central part. Since this force is exerted in a direction, in which movement of the slide 7 is blocked, through the lower end of a support lever 15, there is no fear of a moving distance of the slide 7 being increased.
