Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To passivate a stainless steel in a neutral-weak acid soln. without using harmful substance and strong acid by coating the stainless steel with a soln. contg. a neutral salt electrolyte and hydrogen peroxide at concns. in specified ranges in liq. coating state and executing washing. SOLUTION: For example, a stainless steel strip subjected to final atmospheric annealing or final annealing and pickling, a soln. contg. a neutral salt (such as NaCl) with 0.1 to 5% concn. and hydrogen peroxide with 0.1 to 1% concn. is atomized or, it is immersed therein and is dried repeatedly, and after that, washing and drying are executed. The treating time depends on the temp., and in the case of 30 to 50 deg.C, it is preferably regulated to >=10 min. In this way, the passive coating can be increased more than that by the conventional method using nitric-hydrofluoric acid or nitric acid, and hydrogen peroxide chemically changes into water and oxygen by a treating process or the addition of a catalyst, by which post-treatment for the soln. can be simplified.  This passivating method can be applied to a stainless steel strip producing process and even to an outside job site where a device of stainless steel is assembled and installed.

Filed: 1984-05-08
Abstract: PURPOSE:To ensure the contact between a head and a disk, by positioning a point at which a pivot supports the head directly or under a condition where the pivot pushes the head through a gimbal spring, in the area of the head closer to the disk flowing out end side. CONSTITUTION:In the floppy disk device of this invention, a point at which a pivot 7 supports a head 1 directly or under a condition where the pivot pushes the head 1 through a gimbal spring 6 is positioned in the area of the head 1 closer to the disk flowing out end side. Therefore, the angle ABC can be made smaller and the pushing force f1 can be made stronger. On the other hand, the pushing force f1 can be made stronger and f2 can be made weaker, since the supporting system of this invention can make the f2 weaker from the opposite reason. Therefore, pushing force can be obtained over the entire surface of the head 1 and the pressure distribution does not fluctuate much. As a result, the contact between the head and disk can be ensured.

Title: Control circuit of pull-up resistance
Inventor: NAGAE YASUTAKA
IPC: H03K19/00
Filed: 1981-06-15
Abstract: PURPOSE:To reduce greatly the power consumption which is caused by the pull- up resistance, by separating the pull-up resistance when the input/output signal is set at a low level. CONSTITUTION:In the application mode of a power supply, a P-MOST3 is kept on until the power supply voltage VCC exceeds the threshold voltage of the P- MOST3. Thus an FF consisting of the NOR gates G1 and G2 is initialized. In other words, the points (a), (b) and (c) are set at a low level, a high level and a low level respectively. Thus an MOST2 is turned on to function as a pull-up resistance. Then the points (a), (b) and (c) are set at a high level, a low level and a high level respectively when the input of a terminal A is set at a low  level. As a result, the P-MOST2 is turned off, and the pull-up resistance is cut  off while the input is kept at a low level. When the input is set again at a high level, the point (c) is set at a low level and the terminal A is pulled up.
