Title: Joining method and joining structure by spot welding using together press welding
Inventor: OMIYA SHINICHI
IPC: B23K11/11
Filed: 1993-12-24
Abstract: PURPOSE:To improve the strength of a coupler by spot welding by drawing down a spot welding electrode and the periphery of contact part of a material to be welded by using an insulater indenter when a power is supplied. CONSTITUTION:When the spot welding is performed, the material 13 to be welded is drawn down by bringing into contact with the spot welding electrode 11. Press welding is performed by drawing down the spot welding electrode 11 and the periphery of contact part of the material 13 to be welded by using the insulator indenter 12 when the power is supplied. In such a case, the width of a corona bond part 14 in the periphery of a nugget 15 is set at a value between 20-100% of a nugget diameter 17. In this way, solid joining can be performed by the synergetic effect of temperature and pressure, and a large corona bond part can be formed in the periphery of the nugget on which the spot welding is performed. Therefore, the coupler strength of a joint can be increased to expand a joining area from only a nugget area to the one on which a corona bond area is added.

Title: Photocopying device
Inventor: KUSUNOKI SHIGEO
IPC: G02F1/37
Filed: 1988-12-26
Abstract: PURPOSE:To shorten the time required for copying operation by applying an electrical field to pockels read-out memory crystal and copying an image through the use of the variation in transmissivity due to the incidence of ultraviolet rays. CONSTITUTION:When an original paper 6 reaches an exposure point 17, an exposing process starts here. The pockels read-out memory crystal, this is PROM crystal 3 produces the distribution of a transmission rate zero by the incidence of ultraviolet rays from a laser oscillator 1 to which a voltage is applied from electrodes 2 and 4. Primary light 11 from the laser oscillator 1 generates a secondary high-frequency generating element, that is a SHG 5 secondary high-frequency (ultraviolet ray) and a character pattern on the original paper 6 is recorded. A PROM drum keeps revolution. When an exposed part reaches a transfer point 18, the character pattern is recorded on a transfer paper. The PROM drum further continues to revolve and contents recorded on the crystal 3 are erased with an eraser 9 so that the operation is ready for fresh exposure. The transfer paper 7 moves away from the PROM drum point 18 and is developed by a developing unit 8. Therefore, since no conventional electrification process is required, the copying time is thus shortened.

IPC: A23B7/04
Filed: 1994-11-26
Abstract: PURPOSE: To prepare frozen vegetable giving a cooked food free from softening and boiling collapse after thawing and cooking and having excellent palatability. CONSTITUTION: A whole or roughly cut vegetable is subjected to the tissue strengthening treatment and frozen to prepare a frozen vegetable. This tissue strengthening treatment comprises a process containing the lst step to treat the vegetable at a high temperature and the 2nd step to heat the vegetable in a calcium-containing aqueous solution as essential steps or a process containing the above two steps and the 3rd step to treat the vegetable again at a high temperature. The vegetable is preferably potato. The calcium- containing aqueous solution is preferably an aqueous solution of calcium lactate. A whole or roughly cut vegetable can be frozen by this process without causing the browning of the vegetable, keeping good palatability and preventing the boiling collapse and softening in the thawing and cooking procedures.  This process can provide a frozen vegetable for secondary processing, e.g. plain dishes such as boiled meat and potato, a frozen vegetable to be heated for a long period such as the ingredients for Japanese hotchpotch and a frozen vegetable for retort-cooking resistant to the boiling collapse and softening even under severe heating condition such as heating in a retort.
