Title: Cubic boron nitride composite sintered compact and its production
Inventor: KURATOMI TATSURO
IPC: C22C1/05
Filed: 1986-06-13
Abstract: PURPOSE:To easily and inexpensively manufacture a cubic BN composite sintered compact by blending respective powders of amorphous BN, metals such as Mg, etc., and hard materials such as carbides, etc., in a specific ratio and by sintering the resulting mixture at and under the high temp. and high pressure under proper conditions. CONSTITUTION:The amorphous BN powder (55-75% by volume), the principal metal powder (5-15%) of <=700 deg.C melting point, such as Mg, Sb, Sn, etc., and the hard material powder (40-10%) of carbides, borides, nitrides, silicides, oxides, etc., are mixed to be formed into a starting material for sintering. The above material is heated until 700 deg.C is reached under a sintering pressure of 33,000-61,000kg/cm<2>, so that above-mentioned principal metal powder is melted. Then, heating is intensified with applying hydrostatic pressure to other powder grains via the above molten principal metal and the temp. and pressure conditions in the cubic BN-stabilized region are satisfied, so that individual amorphous BN grains are subjected to transition into cubic BN grains. In this way, the molten principal metal applies liquid-phase sintering to the cubic BN grains and hard material grains. This liquid phase sintered compact is cooled down to 300 deg.C, so that cubic BN composite sintered compact suitable for super hard tool material of solid phase sintered compact can be obtained.

Title: Optical information recording medium
Inventor: SATO TSUTOMU
IPC: G11B7/24035
Filed: 1985-06-24
Abstract: PURPOSE:To eliminate the need for guide grooves and to provide a reduction of cost and improvement of productivity by providing an org. dye recording film by soln. coating on a substrate consisting of a polymethyl pentene resin. CONSTITUTION:The recording film in common use as guide grooves is formed on the substrate by utilizing the difference in the wettability with solvents between the surface treated part and non-surface treated part of the polymethyl pentene resin substrate. More specifically, the org. dye recording film is provided by soln. coating on the substrate consisting of the polymethyl pentene resin to a spiral, concentrical or linear shape. However the polymethyl pentene resin is poor wettability with solvents while having good solvent resistance ad therefore the wettability with solvents is required to be improved by treating the same with either electron ray irradiation or UV ray irradiation. The UV irradiation is preferably, so-called vacuum ultraviolet rays having <=200nm wavelength.

Title: Pulling up semiconductor single crystal
Inventor: FUSEGAWA IZUMI
IPC: C30B30/04
Filed: 1990-05-25
Abstract: PURPOSE:To obtain semiconductor single crystal having a given oxygen concentration distribution by changing intensity of magnetic field applied to semiconductor melt maintained in a quartz glass crucible corresponding to length of single crystal bar pulled up. CONSTITUTION:A silicon single crystal bar 1 is formed by pulling up seed crystal 4 in contact with the surface of melt 3 in the pulling direction at low speed (v) while rotating a quartz crucible 2 and the seed crystal in fixed low speed. Oxygen dissolved in the melt 3 is bonded to Si, made into volatile SiO, released from the melt 3, entrained and removed with an argon gas. However, since oxygen not released and removed as SiO is left in the melt 3, the silicon single crystal bar 1 does not become completely pure and contains oxygen. Since oxygen contained in the silicon single crystal 1 consists essentially of interstitial oxygen in a bonded state to silicon atom, concentration of oxygen existing in the silicon single crystal can be known by measuring concentration of interstitial oxygen.

Title: Rotary kiln with combustion chamber for semi-fused reduction smelting
Inventor: ARAI HARUO
IPC: C22B1/16
Filed: 1982-08-09
Abstract: PURPOSE:To increase the yield of valuable metals by a structure wherein the distance between the tip of a burner and the discharge end of the kiln and the length of the combustion chamber in the same direction as the axis line direction of the kiln are made at the ratio of specified percentages of the inner diameter of a shell. CONSTITUTION:When the burner is at the position indicated by the burner 5a, a slag ring first appears at the position abut 15 meters inside the kiln from the discharge end thereof, while, when the burner is at the position indicated by the burner 5b, the slag ring appears in the first place at the position about 18.5 meters inside the kiln from the discharge end thereof. As a result, the effect of suppression of charging amount of raw material to be charged due to slag ring is remarkably influenced by the position in which the slag ring appears in the first place or the deeper the dam ring is formed within the kiln the lower the production efficiency becomes. Furthermore, when the relative position of the tip of the burner to the discharge end of the kiln is smaller than 70% of said inner diameter, the temperature of the product stopped by the dam ring can not be maintained within its suitable temperature range. On the other hand, when siad relative position is larger than 90%, not only the stagnation of the flow of charging raw material and consequently lowering of the productivity are resulted, but also the service life of the kiln is shortened. Consequently, said relative position must be kept in the range of 70-90% of the inner diameter of the shell.

On the other hand, a proper ventilation is set so that the drying medium M flows, for example, at approximately 1 m/s within the drying machine 2 and garbage A with, for example, water content of 55% W.B is dried so that the wafer content reaches 10% W.B.

Title: Mask for exposure and its material
Inventor: SHINDOU MASANARI
IPC: G03F1/54
Filed: 1982-08-07
Abstract: PURPOSE:To improve the surface strength, see-through effect and light shielding effect at wavelengths of light for exposure by using an amorphous semiconductro layer, especially an a-Si:H layer as a light shielding film. CONSTITUTION:An a-Si:H layer 3 is uniformly coated with a known photoresist 28, a previously manufactured mask 7 for exposure is mounted, and exposure is carried out. The under photoresist 28 is exposed to beams 8 for exposure in the form of a prescribed pattern through the non-mask parts 9 of the mask 7. The unexposed of the photoresist 28 are removed by etching. The under a-Si:H layer 3 is etched by plasma etching using the hotoresist 28 as a mask. In spite of the local action of charges of plasma on a substrate, the charges are not locally accumulated on the substrate because the charges are freely moved in an electrically conductive transparent layer 4. Thus, a mask 11 for exposure is formed.
