Title: Manufacture of etching mask
Inventor: KAWASHIMA KENJI
IPC: H01L21/302
Filed: 1988-08-04
Abstract: PURPOSE:To improve verticality and etching resistance by providing a mask material in an etching region formed on an object to be etched by etching, baking it at a high temperature, and masking the baked material. CONSTITUTION:A photolithography resist layer 2 is patterned on a substrate 1, and with the layer 2 as a mask a groove 1a is formed by etching. After the layer 2 is removed, it is again coated with a resist layer 3, and so developed that the layer 3 filled in the groove 1a remains as it is. Thereafter, the layer 3 is baked at a high temperature to enhance the etching resistance of the resin in the groove 1a, and with it as a mask a GaAs substrate 1 is etched by reactive ion beam etching using Cl2 gas plasma. Thus, a mask having large etching resistance and excellent verticality of its side face is formed, and it can be etched with high verticality.

Title: Wiring accessory mounting structure
Inventor: ETSUNO MASAYUKI
IPC: H02G3/02
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To facilitate work and have cold air hardly pass through by passing a wire arranged in a wall through a slit shape passage hole of an airtight packing and connecting it to a terminal of a wiring accessory. SOLUTION: A wire 5 arranged in a wall 6 is pulled out from an opening 61, passed through a slit-shape passage hole 35 in an airtight packing and connected to a terminal of a distribution board 1. Although the slit shape passage hole 35 is narrow and long, since the airtight packing 3 is sufficiently elastic, the wire 5 can be made to pass through by widening its width, for making a work easy. In addition, the opening of the slit shape passage hole 35 is shrunk through the elasticity of the airtight packing 3 and it is made difficult for air to pass through. Thus, the plural wires 5 arranged in the wall 6 are connected one by one to the terminals of the distribution board 1.  A natural rubber plate, a plate body of a synthetic rubber such as ethylene-propylene-diene terpolymer, a plate body made by foaming the rubber, foaming body of soft polyurethane resin are preferable for the airtight packing 3.

Title: Discharge tube apparatus
Inventor: MIURA MASAHISA
IPC: H01J61/10
Filed: 1982-11-08
Abstract: PURPOSE:To multiply brightness in order to increase efficiency and reduce power consumption by providing two or more second electrodes where beta<+> radioactive element metal is arranged like lattice are disposed in the intermediate space between two electrodes at both ends of discharge tube. CONSTITUTION:The electrons emitted from two electrodes 1 in both ends of discharge tube run toward the electrode in the tube, the internal electrons collide with the third electrode 3 made of metal thin plate of the beta<-> radioactive element (mixed and processed beryllium). Thereby, the secondary electrons are multiplied and reflected. These electrons, then, collide with the second electrode 4 formed like the lattice (or mesh) made of the beta<-> radioactive element (mixed and processed beryllium) metal. Since the second electrode 4 is emitting the position which is the beta<+> radioactive ray, said primary (and secondary electron beams severely collide with such positron and generate a large amount of ultraviolet ray. In case, the amount of electrons of such electron beam is equal to the amount of position, energy of such ultraviolet ray becomes the square times of such ultraviolet ray and the ultraviolet ray collides with the phosphor, emitting the light. Thereby, the brightness of square times the conventional one can be obtained with the same power and the energy can be saved.

Title: Optical modulating element
Inventor: SUZUKI MASATOSHI
IPC: G02F1/015
Filed: 1988-08-05
Abstract: PURPOSE:To execute optical modulation at high speed by a low voltage being free from the increase of a modulation voltage and the decrease of a band width by a space charge effect by constituting the optical modulating element so as to equalize the number of absorption carriers per unit length, so that an absorption coefficient becomes smaller on the incident end side where the light intensity is large and the absorption coefficient becomes larger on the emitting end side. CONSTITUTION:The upper or the lower clad layer of an optical waveguide layer is constituted of plural low impurity concentration areas 9 and plural high impurity concentration areas 10, and constituted so that each length of plural high impurity concentration areas 10 is made larger successively against the light advance direction, strength of an electric field in a waveguide is enlarged, and a variation of the number of absorption carriers per unit length is reduced. That is, when the absorption coefficient is made small in a part where the light quantity is large, and the absorption coefficient is made large in a part where the light quantity is small, deterioration of the band and an increase of a modulation voltage are not generated even when a high intensity light is made incident. In such a way, even if the incident light intensity increases, the optical modulating element which can modulate at high speed by a low voltage is obtained.

IPC: G11C11/15
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To realize easy writing and highly reliable memory by exhibiting a large magnetoresistance change even in a low magnetic field. SOLUTION: A conductor wire 8 is disposed on a magneto-resistance element part made of a metal artificial lattice layer 9 epitaxially formed on an SOI board 9 made of Si (100) single crystal layer 3 formed on an insulating film 2. Since the crystal is epitaxially grown on the board 9, no irregular thin film growth occurs in an insular growth. The contribution of the boundary, between soft, hard magnetic layers 4, 6 and a nonmagnetic layer 5 is large in the magnetoresistance effect of the lattice 9, but since the epitaxial film is uniformly crystal grown, a flat boundary can be realized to obtain a large magnetoresistance effect is obtained.  Since the epitaxial film (100) has an axis of easy magnetization in the direction (011) of the film surface, the square of a magnetization curve is excellent, and at the time of applying a magnetic field in the direction of the axis, the anti-parallel state of the magnetizations of the layers 4, 6 can be realized, and the magnetization resistance value becomes large as well.

Title: Variable coil with the aid of eddy current
Inventor: SATO KAZUNORI
IPC: H01F21/12
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost coil with a simple structure whose inductance is variable. SOLUTION: When a switch is turned off and an auxiliary coil 3 is open, the inductance of a main coil 2 is the same as that of a conventional coil, since the auxiliary coil 3 does not act on a ferrite core 1. When the switch is turned on and the auxiliary coil 3 is short-circuited, the auxiliary coil 3 becomes a loop which crosses the inner magnetic flux of the ferrite core 1. Accordingly, an eddy current is produced at the auxiliary coil 3 and the inductance of the main coil 2 becomes lower than that at the time of opening of the auxiliary coil 3. In this way, the inductance of the main coil 2 can be switched between two levels by opening and short-circuiting of the auxiliary coil 3.
