Patent JP-H01145819-A (JP)
Title: Manufacture of semiconductor device
Inventor: NISHIMUTA TAKESHI
IPC: H01L21/316
Filed: 1987-12-01
Abstract: PURPOSE:To reduce leakage current easily generated in a boundary between a P<-> type silicon layer and a silicon oxide film by removing by etching the surface region of the P<-> silicon layer to be easily inverted to an N-type, and forming a final silicon oxide film thereon. CONSTITUTION:Before a final oxidizing step, a surface region is etched to a depth of approx. 0.5mum, thereby removing a P<--> type layer. A final SiO2 film 19 is formed thereon. Accordingly, in a finally obtained configuration, a boundary 12a of a p<-> type silicon layer 12 from the film (surface protective film) 19 and its near region (boundary region) is affected by only one oxidation (final oxidation). Accordingly, the part becoming of P<--> type does not exist. From this, even if the film 19 is formed and a reverse voltage is further applied between a p<+> type region 15 and an n<+> type region 18, a boundary region is hardly inverted to be of n-type, and a channel 1a is not formed. That is, the leakage current of the boundary can be sufficiently suppressed.

Title: Tension levelleer line
Inventor: KANETANI TETSUO
IPC: B21D1/05
Filed: 1990-11-13
Abstract: PURPOSE:To straighten even the thinner sheet without making the diameter of work roll smaller by setting the trimmer for trimming the ear part of the material to be straightened at the upstream side of the tension leveller. CONSTITUTION:At first, an ear part having fine cracks generated on the rolling process, etc., is removed with a trimmer 6, then, the tension is applied with the roll group 1-2, and it is straightened by working with bending with the work roll 3. Therefore, the extra fine sheet can be straightened even without making the diameter of the work roll smaller, and the sheet passing speed can be made higher and the high productivity can be realized and even for the thick plate, the shape can be straightened with the same equipment.

Title: Rotary displacement type actuator
Inventor: YAMAMOTO HIROSHI
IPC: H01L41/09
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the size of an actuator by a simple structure by providing the actuator with an end cap having arms which are inclined to a specified direction from the lines which connect connections between the periphery and a central plate of the end cap and the center of the central plate. SOLUTION: An end cap 2 consists of the periphery 3, a central plate 5, and a plurality of arms 4. When an electric field of a specified magnitude is applied between an upper and a lower electrode layer 20, the electric field works on a cylinder-shaped piezoelectric layer in its thickness direction and thereby contraction force F which goes toward the center appears at the periphery of the layer due to a piezoelectric effect. The contraction force F works on the periphery 3 of the end cap 2 and pushes the ends of the arms 4 toward the center and thereby torque which rotates the central plate 5 in a specified rotary direction is generated and then the central plate 5 rotates around a central axis which passes the central point 0.  At that time, the generated rotation torque is effectively transmitted to the central plate 5 because the arms 4 are inclined to a specified direction from the radius direction. As a result, the size of an actuator can be reduced by a simple structure.

Title: Magnetic recording medium
Inventor: UCHINAMI SHUNICHI
IPC: G11B5/71
Filed: 1989-11-22
Abstract: PURPOSE:To attain high-density recording without deteriorating lubricity in the environment where the medium is used by forming a magnetic layer on a flat substrate having <=50 Angstrom  center line average roughness Ra and applying a lubricant having >=50 deg.C m.p. on the surface of the medium. CONSTITUTION:The magnetic recording medium is provided with the flat sub strate 1 having <=50 Angstrom  center line average roughness Ra and the lubricant 5 which is solid at ordinary temp and has >=50 deg.C m.p. In this case, since the lubricating oil is solid in the environment where the medium is used, the oil is hardly moved on the surface of a disk, the oil is not absorbed even by the flat substrate, and the dissipation of oil is hardly caused due to rotation. Further more, a functional group is incorporated into the lubricant to enhance its binding power with the protective film such as carbon film and SiO2 film on the disk surface, hence the lubricant is not moved on the disk surface, and the above- mentioned action is further enhanced.

Title: Method for energizing metal strip
Inventor: HIROTA YOSHIAKI
IPC: H05B3/00
Filed: 1992-10-19
Abstract: PURPOSE:To uniformly load the pressure to a metal strip and to prevent the generation of spark and defective form by holding the metal strip therebetween while directly and mutually bringing both rolls into contact with each other at the outside of both edge parts of the metal strip and energizing them. CONSTITUTION:While directly and mutually bringing both rolls 1, i.e., both energizing rolls or the energizing roll and a pressing roll into contact with each other at the outside of both edge parts of the metal strip 2, the metal strip 2 is held therebetween. Since the pressure is concentrated to the mutual contacting part 3 of both rolls 1, 1, the deformation of the edge parts of the metal strip 2 by excess pressure causing the development of the defective form can be prevented. Further, since the metal strip 2 receives the uniform pressure from the energizing roll, the generator of spark caused by the defective contact can be prevented. As the roll 1, it is desirable to use a roll having small Young's modulus.

IPC: B60H1/32
Filed: 1994-12-08
Abstract: PURPOSE: To prevent water condensed over the outer surface of a cooler case for the vehicular air conditioner from falling down in a cabin. CONSTITUTION: In a cooler case 10 housing an evaporator 7 inside, at least a part of the outer surfaces of parts set in the inside of a cabin is formed into a plurality of dewing prevention ribs 24. Even if the inside of the cooler case 10 is cooled by the evaporator 7, since heat exchanging is well performed of its outer surface by the ribs 24 the large surfaces of which are brought into contact with air within the cabin, the surface of the cooler case 10 is so increased in temperature as to be close to the temperature of cabin air, and moisture contained in cabin air is thereby condensed over the outer surface, so that dew condensation is thereby prevented. Therefore, there is no fear of dropping condensed water in the cabin even if an insulator as recommended in the past technique is not used.

Abstract: PURPOSE:To quicken hardening time and to improve facilities in transportation and handling by enclosing the core material of a tension steel member with an after-curing composition, and covering it with a sheath having an electric heating conductive member buried in its outer periphery. CONSTITUTION:An after-hardening composition 2 is applied to the circumference of a steel member 1 serving as core material to proper thickness to form an inner filled up layer.
