Title: Dry etching method
Inventor: KADOMURA SHINGO
IPC: H01L21/3205
Filed: 1992-01-28
Abstract: PURPOSE:To suppress the loading effect and improve the selectiveness for a Ti barrier metal when a W layer (Blk-W layer) formed by the blanket CVD method is etched back. CONSTITUTION:In the etch back process of a Blk-W layer 5, Br gas is used at least in the vicinity of the interface with a TiN barrier metal 4 and a wafer is heated. The reaction product WBr6 of Br and W has relatively low vapor pressure and the reacting product TiBr4 of Br and Ti has relatively high vapor pressure. Namely, the etching speed is decreased and the loading effect is suppressed compared with the case that F gas is used for etch back and higher selection ratio is allowed compared with the case that Cl gas is used. For example, when HBr/SF6 mixed gas is used for just etching and HBr is used for over etching, a connecting hole 3a is flatly buried by the high-speed etch back.

Title: Fluid torque converter
Inventor: NISHIMURA SADANORI
IPC: F16H41/26
Filed: 1982-03-09
Abstract: PURPOSE:To provide a fluid torque converter which can make up for a decrease in passage width in a stator impeller with an increase in passage height to keep a passage area constant and fix a meridian surface component, so as to prevent disturbance of a flow. CONSTITUTION:The torque converter is a flat torque converter forming a truss having a meridian surface section, the radial size H of which is larger than the axial size L. A blade 8a of a stator impeller 8 is formed like a profile. In this case, the width of each passage 9 formed among the blades is narrower than that of each passage of other impellers 4, 5, because the thickness of each blade increases. An inner core 86 of the stator impeller 8 is deformed from a curve form A indicated by a dotted line to a form B indicated by a solid line, to make up for a decrease in passage width 1 with an increase in passage height b, so that velocity of flow meridian surface component Cm on the average streamline is kept constant.

Title: Production of electro-optic element
Inventor: MATSUKAWA FUMIO
IPC: G02F1/13
Filed: 1979-03-24
Abstract: PURPOSE: To prevent the entry of air bubbles into the liquid crystal in a hermetic case by directing the injection port of the case upward, holding the vessel containing fluid such as liquid crystal above the injection port and injecting the liquid crystal at the time of injecting the liquid crystal, etc. from the injection port of the hermetic case.  
     CONSTITUTION: At the time of injecting fluid, such as liquid crystal or electrochromic material, into the cell of the element, for example, liquid crystal 1 is put into a liquid crystal pot 12 up to the XX' line of the liquid crystal well 14 containing a net 15 of stainless steel or the like leading the liquid crystal in said pot to a dropping port 13. This pot 12 is held in a bell-jar 7 by supporting yarns 16a, 16b. An empty cell 6 is held with its injection port 5 being directed upward, on the movable holding table 17 of the jar 7 and is evacuated by a vacuum exhaust system 10, after which the table 17 is moved upward to let the injection port 5 touch the liquid crystal 1 bulging out at the dropping port 13. If the inside of the jar 7 is leaked after this, the liquid crystal 1 infilters into the empty cell 6. When the cell 6 inside is filled with the liquid crystal 1, the table 7 is lowered to detach the cell 6. Thus, should any air bubbles enter the cell 6, they may be readily removed by again evacuating the jar inside.

Title: Voice compression circuit
Inventor: KITAHARA KATSUYA
IPC: H04R3/00
Filed: 1992-02-24
Abstract: PURPOSE:To provide the compression circuit with an excellent characteristic at a low cost by decreasing a sound volume when a voice signal is large and increasing the sound volume when the voice signal is small. CONSTITUTION:This compression circuit is provided with an adder 4 for left/right voice signals, a rectifier circuit for the sum signal and a smoothing circuit for the rectified signal, and an output signal of the smoothing circuit 2 activates a voltage controlled amplifier circuit (VCA) or a conventional sound volume control circuit (or sound volume control IC). Thus, an output voltage of the smoothing circuit 2 is made correspondent to the mean level of the voice signal. When the voltage is inputted to a control terminal of the VCA 1 voice so that the voltage is smaller as the sound volume is larger, and when voice signal is larger, the control terminal voltage of the VCA 1 is decreased to decrease the sound volume, and when the voice signal is smaller, the control terminal voltage of the VCA 1 is increased to increase the sound volume. Furthermore, this is similar to the case of using a conventional sound volume control circuit without use of the VCA 1, and when an output voltage of the smoothing circuit 2 is subtracted from the sound volume control voltage, the sound volume is decreased when the voice signal is lager and the sound volume is increased when the voice signal is smaller.

Title: Semiconductor laser module
Inventor: UMEKI KAORU
IPC: H01S5/00
Filed: 1989-02-17
Abstract: PURPOSE:To obtain a module which can be miniaturized and has the optical axis easily adjusted and has a high productivity by arranging a multimode optical fiber having the same diameter as a single mode optical fiber so that this multimode optical fiber is unified with the single mode optical fiber. CONSTITUTION:A graded index type multimode optical fiber (MMF) having the same outside diameter as a single mode optical fiber (SFM) 8 is so arranged that this MMF 9 is unified with the front end of the SMF 8. Thus, the spot size of the SMF 8 is expanded by several times in the front end of the MMF 9, and a lens which is conventionally required in the front end of the SMF 8 to relax the precision of alignment of optical axes and has several to several tens mm<3> volume is unnecessary to miniaturize the module. Since it is sufficient for alignment of optical axes of fibers if outside diameters of optical fibers are matched to each other, the optical axis adjustment is very facilitated.

Filed: 1980-03-24
Abstract: PURPOSE: To eliminate a problem of the quality of cooling water for a mold by spray-coating a temp.-sensitive magnetic material on the outside wall surface of the mold to form a film thereof.  
     CONSTITUTION: A spot facing of a predetermined shape is beforehand performed on the outside wall of a mold 1 in the level detecting position for the molten steel 5 in the mold 1. After this spot-faced surface is pretreated, a power material or wire material having been controlled to the alloy components of the temp.-sensitive magnetic material is spray-coated, whereby a spray-coated film 7 is formed. The film 7 changes its specific magnetic permeability with a temp. change owing to the level change of the molten steel 5, and the impedance of a detecting coil 4 separately opposing said film 7 changes. This change is measured, whereby the molten steel level is detected. At this time, the film 7 does not peel off even if the cooling water for mold 6 is inferior in quality.
