Title: Welding of lead wire of resistor
Inventor: ARAI TOSHIO
IPC: H01C17/28
Filed: 1988-03-16
Abstract: PURPOSE:To stabilize the welding strength and to prevent an electrode from being worn away by a method wherein, when a lead wire is to be welded to a resistor electrode; electricity is applied to form a waveform so as to make an applied electric current zero and a welding operation is executed after the waveform has been raised to a welding current value along a curve of secondary degree while a pressure is being applied to a tip part of the lead wire which has been cut to be V-shaped and to a part adjacent to the resistance electrode and it has been kept at a peak current value for a prescribed time. CONSTITUTION:A lead wire tip part 5 is cut to be V-shaped; while a pressure of 3-4kg is applied from a lead wire holding electrode 3 in order to raise an electric current value corresponding to a V-shaped volume and a welding process, a raise waveform corresponding to a high portion of a specific resistance of a lead wire of a current waveform is delayed. By this setup, the tip part of the lead wire 5 which has been cut to be V-shaped is softened slowly; the Joule heat is generated also at a resistor electrode 2; the rise waveform is raised suddenly within 3-4msec before being melted; a peak current is held for a short time of 3-4msec; a welding operation is executed. By this setup, the lead wire 5 is not melted up to the tip part of the lead wire holding electrode 3; accordingly, the tip part of the lead wire holding electrode 3 is not worn away.

Filed: 1988-03-16
Abstract: PURPOSE:To enable the sufficient heat treatment for curing an oriented film for a liquid crystal by providing a coloring agent supplying layer contg. a coloring agent on a glass substrate to a prescribed shape and subjecting the layer to a heating treatment, thereby coloring the glass substrate to the prescribed shape. CONSTITUTION:The coloring agent supplying layer 9 contg. a pigment which forms a red color is spin-coated on the glass substrate 1 and thereafter, a photosensitive resin film 8 is coated over the entire surface. A photomask 10 having the pattern corresponding to a red filter part is pressed to said film and the photosensitive resin film 8 is exposed by UV light and is developed so that the coloring agent supplying layer 9 remains only on the part desired to be dyed on the glass substrate 1. The photosensitive resin film 8 is removed by a remover. The layer is then subjected to the heating treatment to color the glass substrate 1. The coloring agent supplying layer 8 is removed by fuming nitric acid to complete the red filter part 4. Since the glass substrate itself is colored, the color filter which withstands the heating treatment at the time of curing the oriented film is obtd.

Abstract: PROBLEM TO BE SOLVED: To raise the output of a nitride semiconductor element and also to raise the luminous efficiency of the element by a method wherein the film thickness of at least either of a first nitride semiconductor layer containing In and a second nitride semiconductor layer having a composition different from that of the first nitride semiconductor layer is formed in a film thickness of a specified value or lower. SOLUTION: An N side nitride semiconductor layer, which is the N side nitride semiconductor layer on one side of P side and N side nitride semiconductor layers sandwiching an active layer 7 between them and is located under the lower part of the layer 7, has an N side multilayer film layer 6 formed by stacking a first nitride semiconductor layer containing In and a second nitride semiconductor layer having a composition different from that of the first nitride semiconductor layer. The film thickness of at least either of the first nitride semiconductor layer and the second nitride semiconductor layer is formed in a film thickness of 100 angstroms or thinner.  Thereby, a thin film layer of the N side nitride semiconductor layer is formed in a film thickness thinner than an elastic critical film thickness to modify the crystal of the thin film layer and the crystallizability of the first or second nitride semiconductor layer, which is stacked on the thin film layer, is modified. Accordingly, as the crystallizability of the whole multilayer film layer is modified, the output of a nitride semiconductor element having the active layer between the P side and N side nitride semiconductor layers can be raised.
