Title: Manufacture of electric contact point
Inventor: NAKABAYASHI TAKASHI
IPC: H01H11/04
Filed: 1987-11-09
Abstract: PURPOSE:To make it possible to obtain an electric contact point with the Ag surface of a contact point material being less likely to be sulfurized, without limitation in the contact point, and with less variance in contact resistance by making the contact point material surface rough simultaneously with its forming. CONSTITUTION:A contact point material surface is simultaneously formed and roughened by using a forming punch with its punch surface roughened to 3-10mum. The Ag surface of the contact point material is cleaned by the destruction of a sulfurized film at the time of forming. The irregularity of the roughened Ag surface increases the number of contact points. As a result, contact forces of the electric contact points are concentratedly applied to each of the raised points. This makes the Ag surface of the contact point material less likely to be sulfurized, increases the number of contact point, and makes it possible to obtain an electric contact point with less variance in contact resistances and stabilized performance.

Title: Semiconductor light emitting element
Inventor: YAMAMOTO MASAHIRO
IPC: H01S5/343
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To realize a structure wherein mode control is easy by forming a structure wherein refractive index is highest in a light emission part and light distribution reduces monotonously from the center in a region of a specific range of light confinement. SOLUTION: In a semiconductor light emission device with an InGaAlN layer in an electrode lower part, for example, lamination is carried out so that refractive index is highest in a light emission part of the laminated InGaAlN layer. The device is constituted so that light distribution decreases monotonously from a center at 90% of light confinement and an electrode contact layer is a GaN layer. That is, an active layer has maximum refractive index and refractive index of a semiconductor layer positioned in an outside thereof inclines to reduce to realize a structure to decrease light distribution monotonously at 90% of light confinement. Since the highest refractive index is possible as for a light emission part by using this structure, mode control is possible. Furthermore, a light emission element of low operational voltage can be realized.

Title: Input device for handwritten character
Inventor: KONISHI YOSHIHARU
IPC: G06F3/041
Filed: 1986-12-01
Abstract: PURPOSE:To eliminate the apparent shift between the input and display positions by calculating the shift value of an input character received from a center coordinates of a character frame against this center coordinates and displaying the character holograph with the next input character with a shift given from a position indicated by an indicating part in the direction opposite to the shift direction by the shift value of the center coordinates. CONSTITUTION:An eye 8 of an input operator is shifted in the direction 11 from a point right above the indicating position of a stylus pen 1 and views a picture element 9 from the direction set at an angle theta. Thus the operator sees apparently the element 9 displayed on the surface of the protection glass 3-b at a position 10 shifted from the position indicated by the pen 1 in the direction 11 by a distance DELTAl=tXtantheta (t: thickness of glass 3-b). Thus the holograph of the input character seems as if it shifted from the input position of the pen 1 in the direction 11 by the distance DELTAl. In this respect, the element 9 is displayed with shift given in the direction opposite to the direction 11 by the parallax value DELTAl as long as this value DELTAl is known. Thus the element 9 is apparently displayed at the position designated by the pen 1 for the operator due to the parallax. In such a way, an apparent shift is eliminated between the input and display positions and the natural input of characters is secured like such a case where characters are written on the paper.

Title: Magnetic multilayer film
Inventor: KOMURO MATAHIRO
IPC: C23C14/58
Filed: 1986-12-01
Abstract: PURPOSE:To enlarge an interatomic distance of Fe to increase saturation magnetization and magnetic permeability thereof, by alternately stacking layers of Fe and of a metal having a coefficient fo thermal expansion higher than that of Fe at a substrate temperature fo TM/2 or below and then rapidly heating the stacked body at a specific heating rate. CONSTITUTION:Layers of Fe and of a metal having a coefficient of thermal expansion higher than that of Fe are alternately stacked at a substrate temperature of TM/2 or below (TM: melting temperature). The stacked body is then heated rapidly at a heating rate of 200 deg.C/min. Said element having a coefficient of thermal expansion higher than that of Fe may be Ag, Al, Au, Cu, Co, In, Mg, Ni, Pb, Sn or Zn. If the substrate temperature is higher than TM/2, energy for activating mutual diffusion among atoms is decreased and lattice vibration is increased, whereby interfaces of the multi-layer film become unstable. The rapid heating enlarges lattices of the element having a higher coefficient of thermal expansion, and this acts on the ferromagnetic transistion metal as tension stress. Lattices of the ferromagnetic transistion metal are thereby enlarged and the saturation magnetization and magnetic permeability are improved.

Inventor: BOKU SHOMIN
IPC: H01L21/768
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To improve the diffusion preventing function of a barrier metal film, by annealing the barrier metal film and then by annealing it in situ in sequence with oxygen. SOLUTION: An insulating film 110 having a contact hole and a metal film 130 for an ohmic contact are formed on a substrate 100. Next, a barrier metal film 140 is formed on the metal film 130 and then is annealed. Then, the metal film 140 is annealed with oxygen. A wiring film is formed on the top of the barrier metal film 140 subjected to the oxygen annealing. Therefore, the defects or the fine cracks of the barrier metal film 140 are filled with oxygen to form a thin oxide film, which eliminate the possibility that a substance constituting the wiring film formed on the barrier metal film 140 is diffused in the defects or the fine cracks to produce a junction spike. This can improve the diffusion preventing function of the barrier metal film.
