Filed: 1985-05-22
Abstract: PURPOSE:To make a grinding mark inconspicuous as well as to improve operation efficiency so sharply, by setting a direction of rotation in a grindstone contacting with a wire rod to an optional angle ranging from a funning direction of the wire rod to a direction orthogonal with the running direction of the wire rod and also to such an angle not inclusive of the direction orthogonalized with the running direction of the wire rod. CONSTITUTION:When a flaw detector detects a flaw in a running state of a wire rod 1, a grindstone 3 during rotation, in response to this detection signal, comes into contact with the flawed part and grind it. At this time, a direction of rotation in this grindstone 3 is an almost running direction of the wire rod so that a grinding mark is inconspicuous. And that the running direction of the wire rod 1 and the rotational direction of the grindstone 3 are almost the same, so only with a revolving speed of the grindstone increased, grinding operation is performable without lowering the running speed of the wire rod so sharply.

Filed: 1977-09-19
Abstract: PURPOSE: To achieve breaking operation with a good reappearance property and generation of high voltage by starting the breaking operation at the time point which the current flowing through an energy storage coil is set equivalent to a predetermined value.  
     CONSTITUTION: Switches 3 and 4 are closed and a coil 5 is excited upto a predetermined value decided by a rectifier divice 1. Next, when a breaking instruction may be issued at he time T 1 , the firing phase of the rectifier device 1 is shifted and the output voltage thereof is converted. By taking into consideration the time delay which the voltage will be subrantially conversed a thyristor 7 is ignited at the time T 2 . The current flowing through the rectifier 1 is turned to the thyristor 7 and the rectifier 1 is bypassed. The open instruction to switches 3 and 4 is issuded at the time T 3  after recognizing that the currenton the rectifier 1 is set at a zero. Because the current on a coil 5 continues to attenuate still after issuing the breaking instruction, a thyristor 8 is turned on at the time T 5  which the current will be equivalent to a predeterminded value to break the current applied to the thyristor

Title: Sensor
Inventor: OOHASHI HIROSHI
IPC: G01V3/08
Filed: 1979-08-31
Abstract: PURPOSE: To permit the field-type sensor to detect the passing direction of an object without malfunction by arranging a plurality of sensing wires on both sides of an exciting wire to detect the  difference between the induced voltages of the sensing wires or the ratio of one induced voltage to  the other.  
     CONSTITUTION: When the object M to be sensed passes in the direction of from the sensing wire  3a to the sensing wire 3b, at a position (b) a difference voltage VA-VB between the induced voltages of the sensing wires 3a and 3b is produced. At a position (c) no difference voltage is produced, but at a position (d) a difference voltage is produced. When the object M moves in the  direction of from (a) to (e), VA-VB changes from negative to positive. On the other hand, when  the object M moves in the direction of from (e) to (a), VA-VB changes from positive to negative. In addition, when the output of a level slicing circuit 5 changes from negative to positive as  the object M moves, the output of an AND circuit 14b is obtained as a direction sensing output;  when the output of the circuit 5 changes from positive to negative, a different direction-sensing  output is obtained. By this, the crossing direction of the object M can be distinguished. The constitution, in which the induced voltage difference and the like are detected and passed through the  level slicing circuit, permits the detection of the passing direction of the object without malfunction.
