Title: Endless rolling method in stretch reducer
Inventor: MIZUNUMA SUSUMU
IPC: B21B15/00
Filed: 1982-04-23
Abstract: PURPOSE:To prevent the thickness increase phenomenon at the forward and rear ends of a pipe by beforehand reducing the outside diameter at the pipe end in front of a reheating furnace, welding both base pipes between the reheating furnace and a stretch reducer, and cooling the coupled part to a specific temp. just prior to rolling. CONSTITUTION:The outside diameter of a pipe end is reduced to the diameter smaller than the caliber diameter of the final stand of a stretch reducer in the stage of reducing the metallic base pipe with the stretch reducer. The pipe end is reduced to about 1/3 the diameter of the pipe at the largest. Thereafter, the reduced end parts of the base pipe are butted and joined by welding between a reheating furnace and the stretch reducer. The coupled part is cooled to the temp. lower by >=50 deg.C than the temp. of the base pipes just prior to the rolling. The thickness increase phenomenon at the forward and rear ends of the product is thus prevented in the stage of producing a circular pipe of small diameter.

Title: Recording medium
Inventor: CHIBA MASAHIRO
IPC: B41M5/52
Filed: 1986-03-25
Abstract: PURPOSE:To obtain a recording image having high optical density and excellent in hue, color development, resolving power and background whitness, by providing a porous ink pervious layer and an unporous ink holding layer and containing an undyeable particle having a refractive index of 1.4 or more in the ink pervious layer with respect to a recording agent. CONSTITUTION:Because recording is performed on an ink pervious layer being a recording side by a recording liquid and a recording image is observed from an ink holding layer being an observation side, it is necessary that the ink pervious layer has high affinity to the liquid medium in the recording liquid and low affinity to a recording agent while, because the ink holding layer absorbs and catches the recording liquid temporarily absorbed by the ink pervious layer, it is necessary that the absorbing force to the recording liquid is stronger than that of the ink pervious layer and the affinity to the recording agent is high. In order to improve ink absorbability and to enhance background whiteness, the refractive index of the undyeable particle (thermoplastic or thermosetting org. resin particle) contained in the ink pervious layer is pref. set to 1.45 or more. As the binder for particles or the ink holding layer, a known one having the aforementioned function can be used.

Title: Wiring in semiconductor device
Inventor: ARAKI RIYOUSUKE
IPC: H01L21/768
Filed: 1981-05-06
Abstract: PURPOSE:To reduce the space for connection by a method wherein, when the first and the second polycrystalline Si layers with the different conductive types come into contact with each other to be connected, a metal is placed on this connection to be heat-treated so that said Si layers may be connected with each other through the intermediary of the spike of the metal infiltrated into said Si layers. CONSTITUTION:When the polycrystalline Si wirings 31 and 32 come into contact with each other to be connected, the ohmic connection is obstructed by the resultant PN joint, therefore a metal such as Al placed on the connection is heat-treated at 300-500 deg.C making Al infiltrate into the ends of the wirings 31 and 32 to make the ends conductive through the intermediary of the resultant spike of Al. Through these procedures, the integration of IC and the like may be improved by means of the direct ohmic connection between the polycrystalline Si wirings with the different conductive types.

Abstract: PURPOSE:To easily obtain a pulse output with high accuracy by using magnetic attractive force between a magnetic body fixed to a float and a magnetic body contact on a conductor film which measures a liquid level. CONSTITUTION:A connector 2 is fixed to a flange 1 and the lead terminal 3 from the connector 2 is connected to a conductor film plate 6 for level measurement through a lead wire 12. Further, the thin wire type conductor film is formed on the surface of the conductor film plate 6 and another thin wire type conductor film is also formed in parallel to the former film so that the both are insulated from each other.

The rotary contact 7 is put outside a rectangular tube 5 and coupled magnetically with a magnetic body 9 fixed to part of the doughnut-shaped float 8. Therefore, when the float 8 moves up and down according to the position of the liquid level 10, the contact 7 also moves following up it, so a resistance value corresponding to the height of the liquid surface is outputted.
