Title: Etching of semiconductor substrate
Inventor: OKAMOTO TETSUMASA
IPC: H01L21/306
Filed: 1988-06-24
Abstract: PURPOSE:To form fine, high-aspect ratio and favorably shaped grooves to correspond to a VLSI by a method wherein a uniform amount of oxygen is doped in the depth direction using a variable acceleration voltage ion-implantation device, oxygen implanted regions are turned into SiO2 regions by annealing and the SiO2 regions are removed to form the grooves. CONSTITUTION:A photosensitive organic film 1 is applied on a semiconductor substrate or a thin insulating film and the film 1 is pattered by a photolithography. Then, while an acceleration voltage is varied from 1KeV to 10MeV using a variable acceleration voltage ion-implantation device, oxygen is ion-implanted 3. Then, the film 1 is removed and thereafter, oxygen implanted regions 4 are altered into SiO2 regions by performing an annealing (d) at a high temperature of 1000 deg.C or higher and the SiO2 regions, which are the implanted regions, are removed by wet etching using an HF to form grooves. Moreover, an oxide film is used as a mask for oxygen ion-implantation and the configuration of the grooves can be controlled by the tapered configuration of this oxide film.

Title: Current source circuit
Inventor: ETOU TOSHIYUKI
IPC: H03F3/34
Filed: 1983-08-29
Abstract: PURPOSE:To change a current amplification factor with good accuracy by adding a few transistors (TR) to a current source circuit. CONSTITUTION:The relation of VTlnIIN/IS10+VTlnI1/IS10= VTlnI2/IS12+VTln IOUT/IS15 (1) is established, where IIN is a current of an input signal source 11, I1 and I2 are respectively collector currents of TRs 13, 14 and IOUT is a collector current of a TR15, that is, the relation of IIN.I1/IS10.IS12=I2.IOUT/ IS12.IS15 (2) is established, thus the relation of IOUT/IIN=IS12.IS15/IS10.IS12X(I1/ I2)=IS15/IS10 X(I1/I2) (3) is obtained. The relation of IS10=IS15 is realized easily in an integrated circuit. Equation (3) in this case becomes IOUT/IIN=I1/I2 (4). The current amplification factor is varied easily by controlling the collector current of the TRS 13, 14 in this way. Further equation (4) is realized with high accuracy in an integrated circuit easily.

IPC: F23D11/02
Filed: 1989-06-20
Abstract: PURPOSE:To improve tarring resistance by a method wherein a filter having an inlet and an outlet filter formed integrally with each other is mounted throughout the whole area of the lower inner part of a gasifying pipe to gasify liquid fuel, an air layer is formed to the upper part of the filter, and a communicating pipe through which an oil feed port and a nozzle are intercommunicated is opened in the air layer. CONSTITUTION:A filter 28 located throughout the whole area of the lower inner part of a gasifying pipe 4 is formed of a porous foamed metallic material of Ni-Cr. An oil feed port 5 and a communicating pipe 11 are opened to an air layer 29 formed throughout the whole area of the upper part of the filter 28. By arranging the filter 28 in a manner described above throughout the whole area of the lower inner part of a gasifying pipe to gasify liquid fuel, a gasifying condition is improved, for example, a gasifying area is increased, and the generation of a tar content is difficult to make. Even when a tar content is generated, tar is prevented to the utmost from flowing in the communicating pipe 11 by means of the filter 28, and adhesion of tar to a nozzle 7 can be difficult to make. This constitution enables improvement of tarring resistance.

Abstract: PURPOSE:To make the manufacture of high-characteristic optical guide sheet easy by flowing a high refractive index polymer soln. contg. an ultraviolet polymerizable low refractive index monomer on a transparent substrate which has beforehand been printed on with mask patterns, allowing the solvent to evaporate, irradiating ultraviolet rays from the back of the substrate to polymerize the monomer and allowing the unreacted monomer to evaporate. CONSTITUTION:Mask patterns are beforehand printed on a transparent substrate of quartz, glass, etc. Mixture of one or more kinds of methyl acrylate, m-methyl acrylate and other ultraviolet polymerizable low-refractive index monomers and polycarbonate, polystyrene and other high-refractive index polymers is dissolved in a solvent, and the soln. thereof is flowed on the substrate. After the solvent is allowed to evaporate, ultraviolet rays are irradiated from the back side, whereby the low-refractive index monomer is polymerized and a clad part 2 is made. Next, the unreacted monomer remaining in the part of an optical guide 1 is heated to evaporate in a vacuum vessel. The sheet thus made is stripped from the surface. Thereby, the high-characteristic optical guide sheet of a large refractive index difference between the guide 1 and the clad part 2 is easily manufactured.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray spectroscope capable of controlling the cooling perfor mance with time variation of radiation intensity and obtain constant monochrome light for long time by designing the dimension of cooling structure for refrigerant path on the back of spectral plane of an X-ray spectral crystal in micron order or less and optimizing. SOLUTION: Cooling groove structure with high aspect ratio is formed on the cooling plane of spectral crystal by applying micromachining technic for example, risography technic with the use of X-ray and electrolytic plastic technic, which realizes a cooling mechanism with wide cooling area and active control. By the machining of this cooling groove, temperature distribution in the spectral plane is kept uniform regardless of time variation of radiation light and monochrome light with high quality is obtained for long time. As the machining accuracy is micron order, mechanical defects and distortion for the spectral crystal does not occur and the perfectness of the crystal is maintainable even after the machining.  Also as the strength of the base is improved and the thickness of the crystal is made thin, the heat generated on the spectral plane is efficiently removed and the pattern shape of the groove can be freely designed.
