Title: Magnetic recording medium having excellent electromagnetic conversion characteristics and traveling durability
Inventor: NAKANO YASUSHI
IPC: G11B5/702
Filed: 1989-03-29
Abstract: PURPOSE:To improve electromagnetic conversion characteristics and traveling durability by using Co-contg. iron oxide containing Si and having specific value of coercive force as the magnetic material for a second magnetic layer, using both of modified polyurethane and modified vinyl chloride-vinyl acetate copolymer having negative functional groups as a binder and using chromium oxide as an abrasive. CONSTITUTION:Co-contg. iron oxide containing Si and having the coercive force (Hc) of 750 - 1,200 Oe. is used as the magnetic material in the second magnetic layer. Modified polyurethane and modified vinyl chloride-vinyl acetate copolymer having negative functional groups are both used as the binder and chromium oxide is used as the abrasive. By incorporating Si, dispersibility of the magnetic material is improved. By using the magnetic material of high coercive force in the second layer, output in high frequency region can be improved, as well as the output in low frequency region can be enhanced by the presence of the first (lower) layer. Thereby, the electromagnetic conversion characteristics and traveling durability can be improved.

Title: Method and device for broadside rolling of plate material
Inventor: AWATSUHARA HIROSHI
IPC: B21B1/22
Filed: 1981-05-27
Abstract: PURPOSE:To decrease the deformation quantity of fish tails while improving the deformation power in the central part of a plate material in broadside rolling of the plate material, by maintaining both end parts in the press down direction of the plate material beforehand at a temp. lower than that in the central part. CONSTITUTION:After a plate material 1 heated to a prescribed temp. in a heating furnace 12 is removed onto a table 13, it is conveyed on a run table 14 to a  broadside rolling mill 3. During this course, the material 1 is cooled at both  broadside end parts in a cooler 11, so that it is given the temp. distribution lower than that in the central part of lthe plate width. Then, the material 1 presses between rolls 2 and 2 in that state, whereby it is subjected to prescribed broadside rolling at a uniform draft over the entire length in a conveying direction and a rectangular direction. At this time, the compressive plastic strain of high temp. parts is made larger than that of the low temp. parts and therefore the central part of the material 1 extends longer than the broadside end parts, and if the temp. difference between both is adequate, fish tails are negated by the difference between the both elongation rates and are eliminated.

Title: Passivation for super lsi
Inventor: KOBAYASHI KEIJI
IPC: H01L21/316
Filed: 1987-04-02
Abstract: PURPOSE:To improve the blocking effect of impurity ions and humidity resistance and to enhance reliability, by using two or more layers for passivation films, diffusing ions in another layer of an amorphous film into the grain boundary of one layer of a crystalline film of said two layers, and enhancing the potential barrier of the grain boundary. CONSTITUTION:An amorphous thin film 1 and a crystalline thin film 3 are provided at adjacent positions. As the crystalline thin film 3, an insulating film, which has a grain boundary comprising polysilicon, SiO2, SiN and other oxide and fluoride and the like, is used. As the amorphous film 1, As doped phospho-silicate glass is used. As a crystalline film 2, silicon nitride film 2 is used. Both thin films are bonded and then undergo heat treatment at 500 deg.C for 15 minutes. Thus As is diffused into the grain boundary 2. As a result, the potential barrier of the grain boundary 2 after the As diffusion can be improved to about 0.75 eV in comparison with the low potential barrier of 0.2 eV in the grain boundary of ordinary silicon nitride. Since the movement of impurity ions in the crystal grain boundary 2 is suppressed in this way, the characteristics of a semiconductor element at high temperature and high humidity can be enhanced by about two-three times, thereby the passivation for a highly reliable super LSI can be obtained.
