Patent JP-H05299770-A (JP)
Title: Semiconductor laser device
Inventor: NAKANISHI CHITOSE
IPC: H01S5/00
Filed: 1992-04-24
Abstract: PURPOSE:To obtain a structure wherein the title laser device can be manufactured at good yield and with good reproducibility by a method wherein the equivalent refractive index of the title laser device in the horizontal direction including a stripe part is divided into at least three regions or higher. CONSTITUTION:The relationship of equivalent refractive indexes is a relationship that it is larger in the order of an equivalent regractive index n1 in a protruding part inside a stripe and an equivalent refractive index n2 in a recessed part inside the stripe (n1>n2). The protruding part exists in the equivalent refractive index in a region which is narrower than the width of the stripe. As a result, the width of a waveguide can be made substantially narrower than the width of the stripe in the horizontal direction. In addition, an absorption coefficient alpha1 in the protruding part inside the stripe and an absorption coefficient alpha2 in the recessed part are set to a value close to almost zero. As a result, waves are guided not at an absorption loss but are guided at a perfectly actual refractive index. In addition, the relationship between a waveguide loss alphamn0 in a fundamental transverse mode and a waveguide loss alphamn1 in a primary waveguide mode satisfies ¦alphamn0¦<10cm<-1> and ¦alphamn0¦<¦alphamn1¦, and a mode can be controlled stably even in a high-output operation.

Filed: 1993-05-07
Abstract: PURPOSE:To remove a surface defect caused by fine defects by heating a slab than hot-scarfing it before hot rolling it, hot-rolling it within a specific time and setting each time between rolling passes within a specific time. CONSTITUTION:After the steel slab is heated by a heating furnace 1, the upper and lower surfaces of the steel slab and both longitudinal side surfaces are hot-scarfed, oxygen of high purity is jetted from a nozzle to oxidize, melt and cut the iron. In this way, fine flaws are removed. Rough rolling is performed by a rough rolling mill 5 within one minute after scarfing. When one minute passes after scarfing, the grain field may be oxidized, corroded again to generate fine cracks and to bring a surface defect in succeeding stages. Descaling devices 4 are provided after and before the roughing mill 5. The steel slab is rolled by a roughing mills 6, finishing mills 7 and coiled by a coiler 10. The times between passes of these rolling mills 5, 6, 7, too, are set within one minute.

Title: Juraku-tone wall material and production thereof
Inventor: INAZU TEIZO
IPC: B32B33/00
Filed: 1986-05-09
Abstract: PURPOSE:To obtain a wall-covering material having JURAKU-tone pattern and feeling (a kind of sand wall), by laminating a synthetic resin layer and a thin paper sheet to a base paper and pressing the laminate to squeeze out a part of said resin layer through said thin paper, thereby forming a number of minute protrusions. CONSTITUTION:A base paper 2 (e.g. an air-permeable flame-retardant paper) is coated with a fluid synthetic resin 3 such as polyvinyl chloride and the coated surface is laminated with a moisture-absorbing thin paper 4 having a moisture absorption of >=4mm. The obtained laminate is pressed with a squeezing roll to squeeze out said synthetic resin through minute gaps between the fibers of the thin paper or through minute holes opened by the breakage of minute weak parts of the thin paper. Minute sharp protrusions 5 resembling sand particles are formed by the protruded resin to obtain a JURAKU-tone wall- covering material. A part of fibers continuing to the thin paper are embedded in the minute protrusions and act as an anchor bonding the protrusions to the synthetic resin layer. Accordingly, the falling off of the protrusions can be prevented and the wall-covering sheet can maintain its original feeling over a long period.

Abstract: PURPOSE:To stably perform transmission and reception even in the case that the oscillation frequency error is not small and to extend the error correction range of a reference oscillator by adding an offset to the frequency of the phase reference signal of a demodulator.

Title: Aerosol device
Inventor: MEKATA SATOSHI
IPC: B65D83/14
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent surely a leakage of contents during injection, by fitting a push-button into the stem of a valve via an aligning part. SOLUTION: By detaching a cap 5 to use and then depressing a push-button 9 with an aerosol device erected, the push button 9 inclines around the aligning part 19 of a stem engagement body 18 engaged with a stem 7, and pushes the stem 7 down. By depressing the push-button 9 further, the stem 7 deforms stem rubber 11b and moves down inside a housing 11a, so that the inside and outside of a container 4 communicate with each other. Consequently, contents filled in the container 4 are injected from an injection cylinder 8 via an outlet and an injection passage under gas pressure. Because a bending deformation does not occur in the stem 7 at the time, the stem rubber 11b deforms uniformly to retain hermetic seal performance. As a result, the contents are prevented from oozing from the stem rubber 11b during the injection.

Filed: 1993-04-09
Abstract: PURPOSE:To a stable layer insulating film and flatten it by stabilizing the contact resistance and rising the heat treatment temperature thereafter in such a wiring construction for a semiconductor device that has a contact hole with a large aspect ratio. CONSTITUTION:After a TiN film 6 is formed on the inside of a contact hole 5, a tungsten film 7 is buried into the inside thereof by a CVD method. Then a TiN film 8 is formed thereon to make a wiring layer. Since the film 8 has a higher melting point than that of aluminum, the high-temperature treatment of at least 500 deg.C can be applied thereto after the film 8 is completed. Therefore, the film-formation temperature for a layer insulating film 9 can be increased and the flattening treatment for the film 9 can be also conducted at a high temperature.

Title: Plastic liquid crystal display element
Inventor: KURISU YASUYUKI
IPC: G02F1/133
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain a plastic liquid crystal display element which has a constant inter-substrate connection and is excellent in the uniformity of substrate gaps by using the mixture of two kinds of conductive beads which are formed by applying a metallic plating to plastic minute balls and whose average particle diameters are different by a specific length as the conductive material of a conductive connection part. SOLUTION: A mixture of first conductive beads which are formed by applying a metallic plating to plastic minute balls and second conductive beads whose material are the same as that of the first beads and whose avarage particle diameters are larger than that of the beads by 0.1-0.5 μm, preferably, by 0.2-0.5 μm is used as the conductive material of an inter-substrate conductive connection part. Particles whose particle diameter are large penetratingly enter into substrates at the time of pressing the substrates to increase contact areas of electrodes on the substrates and they stabilize the conductive connection. Particles having particle diameters close to the avarage particle diameters of the first beads occupying the major part of all particles contribute to the making of substrate gaps uniform.  When the difference between avarage particle diameters is too small, the stablizing effect of the conductive connection is lowered and, besides, when the difference is too large, it becomes the cause of ununiformity of the substrate gaps.
