Title: Disk substrate
Inventor: KAIZUKA TAKANORI
IPC: G11B5/82
Filed: 1983-03-30
Abstract: PURPOSE:To obtain a substrate relieving stress due to the difference in expansion coefft. between the substrate and magnetic layers formed on the substrate by coating both sides of a disk substrate with a hard valve metal or its nitride and forming surface layers of the oxide of the metal. CONSTITUTION:Ta, Ti, Zr, Hf, W, Sb, Bi, Nb or Mo as a valve metal or its nitride is deposited on both sides of the base material 1' of a disk substrate such as Al by sputtering, ion plating or other method to form films 4a, 4b. The surfaces of the films 4a, 4b are then oxidized by anodic oxidation, thermal oxidation or other method to form oxide layers 5a, 5b. The pores in the oxide of the valve metal are well sealed, and the oxide undergoes little change with the lapse of time. Since the layers 4a, 4b are present between the layers 5a, 5b and the material 1', stress due to the difference in hardness and expansion coefft. between the material 1' and layers 2'a, 2'b of a magnetic recording medium formed on the layers 5a, 5b is relieved, so the floating stability of a head is improved.

Title: Strain measuring method
Inventor: ITOU HITOMI
IPC: G01B15/06
Filed: 1981-04-08
Abstract: PURPOSE:To measure strain precisely and quantitatively by utilizing correlation between the number of electron channeling patterns and the strain. CONSTITUTION:In general, when an angle of incidence is varied while an electron beam is caused by a scanning electron microscope to strike a crystalline conductive material, such as a metallic material, at one point, an electron channeling pattern appears. This pattern loses contrast when a sample is distorted, so a sample free of strain by sufficient annealing and another sample having prescribed strain are used and the number of pattern lines crossing a prescribed circle drawn on a pattern image is counted. Then, correlation between the number of the lines and the strain is found. This relation is linear, so that the extent of strain is found from said number of lines.

Abstract: PURPOSE:To call for attention of the persons living near the area where a gas sensor is installed and to make it possible to avoid unnecessary confusion for the gas sensor of a 4-line type centralized monitor system by sounding buzzers in the gas sensor before issuing proper alarm. CONSTITUTION:A DC-AC inverter 6 for raising voltage is connected to the power line 1. The AC output of this inverter 6 is supplied to the heater 18a of a gas sensing element 18. When a sintered body that consists of SNO2, etc. as main ingredients and installed between the heater 18a and the element 18 and the other electrode 18b contacts gas, its resistance drops. By making use of this voltage drop, the secondary voltage of a voltage boosting transformer 11 is transmitted to the electrode 18. After a certain time has passed since the output of the comparator (COM) 14 becomes ''H'' level by the output of the element 14, the output of COM17 becomes ''H'' level, and a thyristor 20 is turned on and a relay 4 is actuated. On the other hand COM16 operates before COM17, and when the output of COM16 becomes ''H'' level, local alarming is issued by means of buzzers 21a. If the output of the COM14 is the same still after the local alarming, proper alarming is issued.

Abstract: PURPOSE:To prevent the generation of the abrasion of a magnetic core, the breaking of wire of a detecting coil or the like, and to improve a durability, and to obtain a high reliability inputting pen by covering the magnetic core and the detecting coil, wound around the outer circumference of the core, by a protecting tube. CONSTITUTION:When the apex of the inputting pen is pressed to the surface of an input plate 14, a switch 5 comes to ON, and at the same time, a magnet field, generated from orthogonally intersecting electrodes 12, 13, acts to the detecting coil 2 through the protecting tube 8, and an induced voltage is generated at the detecting coil 2. The said induced voltage is led to an external part through a lead wire 4, connected by a switch, made to ON, and a shield wire 7. In these actions, because the magnetic core 1 is covered by the protecting tube 8, it is never abraded by a direct touch to the input plate 14, and because the detecting coil is covered by the protecting tube 8 as well, there is no fear that it is disconnected by the touch to other things.

Abstract: PURPOSE: To form an excellent resist film having no pinholes on an insulating protection film by deaerating the air remaining between the protection film having a wrong coverage and a fist resist by heating a semiconductor substrate. CONSTITUTION: An insulating protection film 3 is formed on a metal wiring pattern formed on a semiconductor substrate 1, and a resist film 4 is formed on the film 3.

At this time, when the substrate 1 is heated, the air remaining in the hole is deaerated by thermal expansion, and removed from the hole 5. The hole 5 after the deaeration becomes a pressure reduced state, and resist 6 is invaded. Then, organic solvent is dropped on the film 4 while rotating the substrate 1, the upper layer of the film 4 is removed, and flattened. Further, the substrate 1 is heated, dried, a resist film 7 is formed, and then the substrate 1 is baked on a hot plate.
