Title: Amorphous iron alloy with resistance to pitting corrosion, crevice corrosion, stress corrosion cracking and hydrogen embrittlement
Inventor: MASUMOTO TAKESHI
IPC: C22C45/02
Filed: 1982-11-15
Abstract: PURPOSE:To obtain an amorphous Fe-Cr-P alloy with superior resistance to pitting corrosion, crevice corrosion, stress corrosion cracking and hydrogen embrittlement by specifying the amounts of Cr, C, B, C+B, P and C+B+P in an Fe-Cr-P alloy. CONSTITUTION:A molten alloy is sprayed on the inside of a drum rotating at a high speed in an inert atmosphere and cooled at a very high cooling rate to obtain an amorphous alloy. At this time, the alloy is composed of, by atom, 1- 40% Cr, >=0.01% C, >=0.01% B (C+B=2-35%), >0-33% P(C+B+P=7-35)  and the balance Fe. In case of less than the lower limit of Cr, the resistance to  pitting corrosion, crevice corrosion, stress corrosion cracking and hydrogen embrittlement is deteriorated, and in case of more than the upper limit of Cr, it is  difficult to manufacture the amorphous alloy. C and B promote the formation  of the amorphous structure, and P promotes the formation and enhances the corrosion resistance. Only when the amounts of C+B, P and C+B+P are within  said ranges, the amorphous alloy can be manufactured.

Title: Grinding method of rolling roll
Inventor: IIFUSHI JUNICHI
IPC: B21B28/04
Filed: 1984-09-25
Abstract: PURPOSE:To grind efficiently a rolling roll without causing a nicking of whetstone by pressing a whetstone against the surface of a rotating roll and slanting the whetstone reversely to the rotating direction with respect to the direction of a rotating center of rolling roll. CONSTITUTION:In grinding a rolling roll 1 by pressing a whetstone 2 against the surface of rotating roll 1, the pressing direction of whetstone 2, with respect to the direction from a contact point between the whetstone 2 and the roll 1 to a rotating center C, is slanted so that the pressing force F has a component in the direction reverse to the rotating direction of roll 1 shown by the arrow. A degree of 5-40 deg. angle is preferable for a slanting angle theta of whetstone 2. In this way, a reaction against the pressing force of whetstone 2 is relaxed, and the reaction acting on the front-end lower part BM of whetstone 2 is reduced, and the nicking of whetstone 2 is prevented.

IPC: H01L33/00
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To provide an LED display device in which a sheet which is provided around an LED that is fixed to a board is improved in assembling properties. SOLUTION: In this LED display device, a small hole 11 is expanded so as to enable the light emitting part of the LED 10 to pass through it when a sheet 13 is fixed to an LED unit 12, and the sheet 13 is fixed between the lower end edge of the light emitting part of the LED 10 and a board 7. The opening area of the small hole 11 is smaller than the sectional area of the LED 10, and as the small hole 11 is so small as not to come into contact with the outer edge face of a stopper formed on the terminal of the LED 10 with a stopper, so that the small hole 11 functions as a stopper to prevent the sheet 13 from falling out of the LED unit 12 due to the oscillations of the sheet 13 after the sheet 13 is fixed to the LED unit 12. Therefore, the sheet 13 can be held, without applying adhesive agents such as an adhesive double coated tape.
