Title: Position detector for ultrasonic probe
Inventor: SATO YASUAKI
IPC: G01N29/04
Filed: 1988-01-28
Abstract: PURPOSE:To improve operability, portability and economy, by separating mechanical connection between an ultrasonic probe and a probe position detector to detect the position of the probe even when the superconic probe moves singly. CONSTITUTION:An ultrasonic probe 1 is so arranged to be movable freely in a three-dimensional space. A position detecting means of the ultrasonic probe 1 comprises a transmitting element 3 provided in the probe 1, a position detecting sensor 4 provided with a wave receiving element 5 and held in an object 7 to be inspected and a position computing device 13 which computes the position of the probe 1 depending on a time difference among ultrasonic waves for detecting position received with the sensor 4. Thus, for example, four of the sensors 4 (4a-4d) are arranged in square and when time is measured until ultrasonic waves for detecting position reach the respective sensors 4 from the probe 1, the computing device 13 calculates the position of the probe 1 from intersection between hyperbolic curves alpha and beta as determined from an arrival time difference between the sensors 4a and 4c and the sensors 4b and 4d respectively on X and Y axes. This eliminates the need for a position detector having a mechanical connection with the probe 1.

Title: Method of numerically controlling machining of right-to-left symmetric workpiece
Inventor: SUZUKI WATARU
IPC: G05B19/4093
Filed: 1983-02-08
Abstract: PURPOSE:To dispense with the copying of data and the modification of a machining model, by reversing the order or reading of machining data, for a unit processing section in which the direction of the contact of a tool becomes opposite due to the symmetry of a workpiece, to numerically control a processing machine depending on the reversed data. CONSTITUTION:It is previously instructed through a keyboard 8 that processing is reversed and a processing data is converted as X -X. Between processing points a', b', a tape is skipped to a point Mb and the tape is then run in the opposite direction to read the data from the point Mb to another Ma. At that time, abscissas X are changed into those -X. The data is then transferred to a numerical controller 6 to feed a tool T upward oppositely to the forwardly- read data after quickly moving the tool T to the point b', so that the tool performs up-cutting to machine a workpiece under the same condition as the reference side. After the machining to the point a', the tape is skipped in the forward direction to start machining a next processing section. A die or the like is thus completed without copying the data and modifying a machining model.
