Title: Production of coil spring
Inventor: NAKANISHI MITSUAKI
IPC: C23C8/26
Filed: 1991-02-04
Abstract: PURPOSE:To provide the process for production of a coil spring having high fatigue strength which does not require a polishing stage and is simplified in stages and low in production cost. CONSTITUTION:This process for production of the coil spring consists in coiling an iron or steel wire having an oxide film, subjecting the coiled wire to a heat treatment, descaling the wire so as to have <5mum surface max. roughness Rmax and subjecting the wire to a nitriding treatment and a residual stress imparting treatment by shot peening. The wire is subjected to the nitriding treatment after the surface roughness at the time of the descaling treatment stage is lowered. An increase in the surface roughness in shot peening in a residual stress imparting stage is, therefore, effectively suppressed and the surface roughness is lowered. The need for a surface polishing stage after the residual stress imparting treatment stage is, therefore, eliminated.

Title: Memory device having redundant cell
Inventor: NAGAI HIDEKAZU
IPC: G11C29/04
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a memory device such as FeRAM with simplified redundant structure. SOLUTION: A redundant file memory RFL for recording replacement information indicating a defective cell to be replaced with a redundant cell or not is formed of a memory cell of the same structure as an ordinary memory cell and access is made to the redundant file simultaneously with the access to the ordinary memory cell. At the time of access to the ordinary memory cell, the replacement information recorded in the redundant file memory is read simultaneously and replacement to the redundant cell from defective cell is performed depending on the replacement information. With such structure, structure of the redundant file memory may be set equal in the ordinary memory cell and redundant cell and thereby the redundant circuit structure can be simplified.  Moreover, since the data can be written to the redundant file memory like the ordinary memory cell, replacement to the redundant cell from the defective cell and recording of the replacement information can be executed even after the memory chip is accommodated within a package.

CONSTITUTION:The backflow preventive weir 40 is formed from above to below in a blast passage 32 on the upstream side of the ozone generator 35 and the easy back flow of the ozonized air to a suction port 33 is prevented by the backflow resistance thereof in the event of the operation failure of a fan 37 by generation of a fault, such as locking of a fan 38 by foreign matter, etc., or the disconnection of the winding of a motor 39. The ozonized air stagnating in an ozone reaction part 41, therefore, flows gradually toward a discharge pot 34 in a normal route while this air is decomposed by the natural convection via an ozone decomposing catalyst 36. The quantity of the ozonized air which leaks into a refrigerating chamber 10 by blowing backward to the suction port 33 is eventually saturated and balanced while the quantity thereof is suppressed to a small quantity. The suppression of the concn. of the ozone leaking into a refrigerating chamber 10 to <=0.05ppm is sufficiently possible and there is no danger of oxidizing the food in the chamber 10 or harming the user's body. The deodorizing device which is safe even in the event of the generation of the fault in the fan 37 is provided in this way.
