Title: Wire-cut electric discharge machine
Inventor: ITOU TETSUROU
IPC: B23H7/04
Filed: 1982-08-02
Abstract: PURPOSE:To prevent snapping of a wire by detecting an electric discharge position from a current wave form which is expressed as the function of inductance at the discharge point so as to discriminate existence of any concentration of discharge positions and varying a voltage value accordingly. CONSTITUTION:The interpole current I which flows between an article 1 to be worked and a wire electrode 2 is detected by a current transformer CT. The wave form of the interpole current I is different accoding to the inductance determined by the distance L1, L2 between a current feeder 9 and electric discharge points. When the electric discharge points are concentrated, the continuous values of the electric discharge current I during a time T are nearly equal. A detector 30 detects existence of concentration of electric discharge on the basis of this principle.

Title: Optical signal changeover switch
Inventor: KASAHARA MASAO
IPC: H04B10/27
Filed: 1987-05-29
Abstract: PURPOSE:To switch the high-speed/wide-band information signals without losing the high-speed properties by using plural output circuits which produce the answer outputs in response to plural discrimination pulses and detecting a switch changeover signal out of a digital optical reception signal when the coincidence is secured between the output forms of said output circuits and a prescribed signal form. CONSTITUTION:An electric switch driving circuit 2 is set at an optional time position in an optical digital pulse train and this circuit 2 owns plural discriminator pulses and a detector for detection of these pulses. An optical switch is driven by the circuit 2 when the coincidence is secured between the form of the discrimination pulse and the form of the detector. Then the corresponding optical switch circuit 3 is opened and the digital pulse train passes through the circuit 3. In such a constitution, the optical digital pulse signals which are supplied continuously and at high speed can be processed in parallel even with a low-speed signal processing circuit which is so far unable to process those digital pulse signals with no deterioration of the high-speed properties. In addition, the high-speed processing is possible with a latch function added to a buffer amplifier.

Title: Light beam scanner
Inventor: MARUO SEIJI
IPC: H04N1/04
Filed: 1990-05-25
Abstract: PURPOSE:To correct the deviation of optical path difference with a simple structure by approximately matching the axial line of rotation of a scanning mirror to a line including the point on which a light beam is made incident on a scan face. CONSTITUTION:Cylindrical lenses 22 and 23 which shape the laser light emitted from a light source (semiconductor laser oscillator) 1 to spot light, a scanning mirror 33 which scans this spot light, a rotating motor 32 which rotates the scanning mirror 33, and an image forming lens 26 which uses a reflection plate 27 to reflect scanned light to form its image on a recording member 28 are provided. The axial line of rotation of the scanning mirror 33 approximately coincides with a line including the point on which the light beam is made incident on the scan face. Therefore, the optical path difference is approximately eliminated because the laser light is made incident on only one point of the scan line which approximately coincides with the axial line of rotation even during rotation of the scanning mirror 33. Thus, the deviation of optical path difference is corrected with an image forming lens 26 having the simple structure.
