Title: Hardening method for discoid workpiece
Inventor: SUGIYAMA SADAO
IPC: C21D9/00
Filed: 1981-02-24
Abstract: PURPOSE: To prevent overlapping of the start and end part of laser heating in hardening the discoid workpiece by means of laser beam by rotating the workpiece and moving the same in a radial direction.  
     CONSTITUTION: At the start of hardening, the workpiece 14 is beforehand set just before the place where one end of a laser spot 15 comes to the outside circumferential part of the workpiece, and the workpiece 14 is rotated by a jig rotating mechanism at the same instant when the laser of a transmitter 11 is irradiated. At this same instant, the workpiece 14 is moved in the central direction along the centerline 19. When the other one end of the laser spot 15 arrives at the inside circumferential part of the work 14, the irradiation of laser, the rotation and movement of the workpiece 14 are respectively stopped.

Title: Impact print head
Inventor: SHIRAISHI HAJIME
IPC: B41J2/295
Filed: 1990-02-02
Abstract: PURPOSE:To reduce electric power to be supplied to a coil from a power source by a method wherein electro motive force generated by impact force when an armature comes in contact with a core is utilized as a part of supply power to a coil when the armature is operated. CONSTITUTION:An armature 2 is attracted to a piezoelectric film 8 by magnetic force of a permanent magnet 4 under a state wherein a switch 20 is off. When the switch 20 turns off again, since denial with each other of the magnetic force of a coil 6 and the permanent magnet 6 by electrification disappears, the armature 2 is attracted to the piezoelectric film 8 due to the magnetic force of the permanent magnet 4. The piezoelectric film 8 generates strain electromotive force by impact force in this attraction. An electromotive force detection part 16 detects this electromotive force to emit a detection signal. By receiving this detection signal, a selection part 17 turns a transistor 18 off. Therefore, since an electric current generated with the piezoelectric element 8 flows in a path such as piezoelectric film 8   diode 19   capacitor 10  piezoelectric film 8, almost the electromotive force from the piezoelectric film 8 is charged in the capacitor 10.

Title: Bending part structure of endoscope

IPC: A61B1/00
Filed: 1993-02-17
Abstract: PURPOSE:To control the curvature of a flexible tube without using a sliding tube by using a spiral tube with interlock structure in which a plate with a cross section of S-shape is made spiral and its both edges are interlocked each other. CONSTITUTION:A spiral tube 11 in a flexible tube 4 is made by a method in which a band plate is folded to have a cross section of almost S-shape and its both edges are formed to have cross sections of U-shape to interlock each other. A space 13 exists between a pair of tips at folded parts 11a and 11b in this folded part 12. When this is bent or curved, the tips of the bending part 11a and 11b approach each other and the space 13 comes to a nonexisting state 14. In this state, the tips 11a and 11b play a role of lock and do not allow the tube to bend or curve any more. A distance L of the space 13 determines the least curvature radius of the spiral tube 11. By using this property, a depth of bending at each part of the spiral part 11 can be set up.
