Title: Manufacture of contact hole
Inventor: MASUDA YOJI
IPC: H01L21/28
Filed: 1987-05-28
Abstract: PURPOSE:To protect a metallic wiring from being disconnected by a method wherein an insulating film layer to make contact holes is formed of a two- layered insulating layer comprising an insulating film layer to be fluidified by heat treatment and another insulating film layer not to be fluidified by heat treatment to make contact holes with almost vertical or stepped sidewalls. CONSTITUTION:A silicon oxide film (p-SiO2) 12 as an insulating film 12 not to be fluidified by heat treatment is deposited on a silicon substrate 11; then another silicon oxide film (PSG film) 13 with phosphorus added thereto as another insulating film 13 to be fluidified by heat treatment is deposited; and resist patterns 14 are formed on the insulating film 13. Next, the PSG film 13 and the p-SiO2 film 12 are anisotropically dryetched to make contact holes with almost vertical sidewalls. When, these contact holes are heat-treated after removal of the resist patterns 14, the PSG film 13 is melted away to make excellent contact holes in tapered shape without any overhang. Thus, a metallic wiring can be prevented from being disconnected.

Title: Production of carrier for oily material
Inventor: SUGAWARA AKIRA
IPC: C09K5/08
Filed: 1992-05-25
Abstract: PURPOSE:To obtain a carrier from which an oily material hardly ooze out by dispersing the oily material in a base material comprising an ethylene-alpha-olefin copolymer having a specified density and crosslinking the dispersion. CONSTITUTION:An oily material (e.g. a paraffin wax) is dispersed in a base material which comprises an ethylene-alpha-olefin copolymer (e.g. an ethylene- propylene copolymer) having a density of 0.88g/cm<3> or lower and, if necessary, contg. a polyolefin (e.g. a high-density polyethylene) for improving the strengths of the copolymer. The resulting dispersion is crosslinked (e.g. peroxide crosslinking) to give the objective carrier, which has a low tackiness and undergoes little shape change due to expansion and contraction caused by repeated heating and cooling. The strengths of the carrier can be increased by the addition of the polyolefin.

Filed: 1990-05-22
Abstract: PURPOSE:To minimize environmental pollution and to allow a short-time treatment by charging org. industrial waste subjected to a dehydration as a pretreatment into heated oil to dehydrate the remaining water, then incinerating the waste. CONSTITUTION:The raw sludge treated with a water treating device is dehydrated by a dehydrating machine down to about 85% moisture content. The oil, such as edible oil, is heated to 120 to 230 deg.C and the specified amt. of the dehydrated cake is charged continuously into this heated oil and is dehydrated and sterilized for a short period of time. The moisture in the dehydrated cake is fried to about <=10% moisture. The fried cake is taken out of the heated oil and drained of the oil. The cake is burned in some cases as it is without oil draining if such is convenient for the combustion in a post stage. The fried cake makes self combustion and is, therefore, incinerated in an incineration kiln. Since atm. pollutants are contained in the exhaust gases generated by the combustion, the direct discharge of the gases is not possible. The exhaust gases are, thereupon, introduced into a combustion device and are burned at >=600 deg.C.

Title: Method for preventing sheet thickness from varying by roll eccentricity
Inventor: OYAGI FUMIO
IPC: B21B37/66
Filed: 1989-05-26
Abstract: PURPOSE:To easily and at low cost prevent the sheet thickness from varying due to eccentricity of rolls by idling upper and lower backup rolls very small in a difference between outer diameters to each other and starting rolling in a phase minimizing load variation by the eccentricity of the detected rolls. CONSTITUTION:The upper and lower work rolls provided with backup rolls of a rolling mill are driven synchronously to perform rolling. In this rolling mill, the difference between the outer diameters of the upper and lower backup rolls is set in advance within a required fine range. Further, they are idled relatively and the relative phase in the rotational direction is changed. In that case, a kiss-roll operation is performed in each phase state and a relative phase minimizing the load variation due to roll eccentricity is detected and stored. Before the actual rolling is started, these upper and lower backup rolls are idled relatively and after they are paired at a position aiming at this detected relative phase they start rolling. Consequently, the variation of sheet thickness by eccentricity of the rolls is retained in a fine range, no roll slip is followed and high-quality rolling can be performed stably for a long period of time.
