Title: Electron beam welding method between different kinds of material
Inventor: KAMITO YOSHIMI
IPC: B23K103/04
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To realize a method for preventing misalignment of weld bead caused in welding different kinds of material by electron beam welding. SOLUTION: After demagnetizing inside the groove 7 formed between different kinds of material 4, 5, a space H is provided for a prescribed area between the tip end of an electron gun and the surface of the different kinds of material 4, 5, with a magnetic shield pipe 2 arranged at the tip end of the electron gun 1, and the groove 7 is irradiated by an electron beam 6 from the electron gun 1 through the magnetic shield pipe 2. As a result, since the inside of the groove 7 is demagnetized preliminarily, a weld bead 3 is free from misalignment from the center of the groove on the surface of the different kinds of material 4, 5.  In addition, since external magnetic field is shielded by the magnetic shield pipe 2, misalignment of the weld bead 3 is also eliminated inside the groove 7, enabling the different kinds of material 4, 5 to be joined while penetration is secured for a prescribed depth.

Title: Recording and reproducing device
Inventor: KUBO TOSHIMITSU
IPC: G11B5/53
Filed: 1990-01-24
Abstract: PURPOSE:To eliminate misrecording by switching and setting the rotating speed and tape feed speed of a rotary cylinder and enabling read-after-write operation at an operation speed a half as fast as the speed of fast recording and reproducing operation. CONSTITUTION:When the device is switched to an operation state where the tape feed speed is 0.5XNXV0 (N: positive integer) and the rotating speed of the rotary cylinder is 1.5X(N/n)Xomega0 (n: integer equal to or less than 2), the recording and reproducing speed is reduced to N/2 times. Digital data which is inputted in this operation state is stored temporarily in a memory 12 through a data bus line 15, read out and given an error correction code by a code generating and correcting circuit 11, and stored in the memory 12 again. This encoded digital data is read out of the memory 12 after being interleaved as specified, and sent to a digital signal processing circuit. It is checked whether or not the read data has an error to perform read-after-write recording, so the reliability of the recording is improved.

Abstract: PURPOSE:To measure easily and accurately the size of a real mold clamping force, by a method wherein a compression-deforming quantity of one like constituting a single toggle mechanism is detected at a nondividing part where the force is transmitted without being divided. CONSTITUTION:A mold is set up between a stationary platen 2 and movable platen 3, zero point adjustment of a strain gauge 16 is performed in a measuring instrument 19 under a mold breaking state and then a mold clamping actuation is performed. With this construction, since a driving side crank pin 12 is driven by a servomotor through a reduction gear 14, a driven side of the second like 9 is extruded through the first like 8 and a connecting crank pin 10, the movable platen 3 is moved forward through a driven side crank pin 11 and becomes a mold contacting state. Furthermore, when a servomoter 13 is driven, the mold is turned into a lock-lup state where the mold is press-bonded with the force commensurate with its extension. In this instance, since a nondividing part 17 of the second like 9 is compressed by receiving a mold clamping force, the mold clamping force is calculated by detecting its deforming quantity.
