Title: Resistance welding method of laminate
Inventor: SHIBATA YOUICHI
IPC: B23K11/16
Filed: 1983-05-04
Abstract: PURPOSE:To perform titled welding with good productivity without deteriorating non-conductive plates by irradiating an energy beam to the surface of the laminate to open a small hole on the metallic facing plate and a large hole on the non-conductive plates and conducting electricity to both laminates in both hole parts under pressurization by electrodes. CONSTITUTION:Lap resistance welding of, for example, laminates 1, 2 are accomplished by condensing first, for example, a laser beam 8 by a condenser lens 9 to the intended resistance welding position of the metallic facing plate 1a of the laminate 1 to perforate the hole penetrating through the laminates 1, 2. The m.p. and b.p. of the resin which forms resin layers 1c, 2c are much lower than those of the metals of the metallic facing plates 1a, 2a, 1b, 2b and therefore the hole 10a perforated on the facing plates is considerably smaller sized than the hole 10b perforated on the resin layers 1c, 2c. The positions of the small hole 10a and large hole 10b provided to the laminates 1, 2 are pressurized by electrodes 5, 6 of a resistance welding device and the electricity from a transformer 7 is conducted thereto to weld securely the laminates 1, 2.

Title: Coordinate generating device
Inventor: YAMAZAKI EIICHI
IPC: G06F3/0354
Filed: 1990-03-28
Abstract: PURPOSE:To generate three-dimensional coordinate by plural operations on the same plane by substituting the displacement of the 3rd coordinates for one of two-dimensional displacement consisting of the 1st and 2nd coordinates and sending the substituted displacement. CONSTITUTION:When a mouse is moved from a point A to a point B on an XY plane without depressing a three-dimensional sensor switch (SW) 25, a displacement detecting part 1 detects displacement dX, dY and stores the dX, dY respectively in X and Y coordinate registers 32, 33. Since the points A, B are respectively positioned on contours L2, L4, a distance from a point A1 to a point B1 is displacement dZ on a straight line vertical to the XY plane. When the mouse is moved only the dZ along the X coordinate by depressing the SW 25, a value corresponding to the displacement dZ is written in an X displacement register 22 and stored in a Z-coordinate register 34. At that time, the contents of a Y displacement register 23 and a status register 21 are not read out. On the other hand, a status value register 31, and the registers 32, 33 still store the preceding values.

Filed: 1984-04-20
Abstract: PURPOSE:To attain the editing of punch-in, etc. by setting a reproduction head before a record head for DA (digital audio) signal and therefore reproducing the record conents of an optional DA track prior to the record to said track. CONSTITUTION:A magnetic head HDA-PB for reproduction is set before a magnetic head HDA-REC for record of DA signal. Therefore the record contents of an optional DA track can be reproduced prior to the record to said track.
