Abstract:
To avoid degradation of performance of a storage apparatus even when access biased to writing or reading of data is performed in a buffer memory that adopts a dual ring buffer system as a data structure. A sector buffer for caching an access request is provided in a DRAM of the storage apparatus. The sector buffer has a first ring buffer (BUF_W) that temporarily holds an external write request for a recording medium in advance of its process to the recording medium, and a second ring buffer (BUF_R) that retains data read from the recording medium according to an external read request for the recording medium. An MPU of the storage apparatus shifts a BPAGE of the BUF_R or BUF_W according to external access patterns to the recording medium to thereby change the buffer sizes of the BUF_R and BUF_W.
Abstract:
A production method of an insulating layer includes a step of forming a first wire, a step of forming an insulating layer as a stack of M layers by repeatedly carrying out steps of laying and baking an insulating material on the first wire M times (M is an integer satisfying M≧3), and a step of forming a second wire on the insulating layer. An N-th insulating material used in formation of the N-th insulating layer (N is an integer satisfying 2≦N≦M−1) is baked at a temperature lower than a softening point of the N-th insulating material, and baking temperatures in formation of the (N+1)th to the M-th insulating layers are not more than the baking temperature in formation of the N-th insulating layer.
Abstract:
A steering wheel which has a core, a cover covering at least a part of the core, a mount member mounted on the cover and a finisher mounted on the mount member. The mount member is fixed to the cover, and the finisher is fixed to the cover through the mount member. The finisher is engaged with the mount member. The core, the cover, the mount member and the finisher in combination form a grip of the steering wheel. The cover is lower in hardness than the core. The mount member is higher in hardness than the cover. The mount member is formed through an insert molding method.
Abstract:
The present invention relates to efficient execution of signal read error recovery processing in a signal recording and regenerating apparatus. A table is used to define the execution sequence of a plurality of error recovery processings, one structure is assigned to the table correspondingly to each error recovery processing, and an address for calling a corresponding error processing and moreover and a structure address corresponding to an error recovery processing to be executed before and after the present structure are included in each structure. By rewriting the address of the previous and forward structures by the LRU method or the weighting method, it is possible to change the chained relation between structures and more quickly execute the optimum error processing.
Abstract:
A ferrous alloy is formed with a Fe--Cr stainless steel having a Vickers hardness of 400 or more as a substrate and a Fe--Al diffusion layer having a thickness of 2 to 50 .mu.m. The diffusion layer contains at least 90 vol % of an intermetallic compound of Al and Fe relative to a total volume of the diffusion layer. The Al content included within a depth of at least 2 .mu.m of the diffusion layer is 35 to 65% by weight based upon total weight of a region of the diffusion layer ranging up to the thickness of at least 2 .mu.m. It is preferred to use as the substrate a precipitation-hardening stainless steel comprising 66 to 81.9 wt % of Fe, 15 to 20 wt % of Cr, 3 to 13 wt % of Ni, and one element selected from 3 to 6 wt % of Cu, 0.5 to 2 wt % of Al, and 0.01 to 0.2 wt % of a total of C and N, or a high carbon stainless steel comprising 73 to 89.9 wt % of Fe, 10 to 19 wt % of Cr, 0.1 to 1.2 wt % of C, and less than 3 wt % of Ni. The ferrous alloy may be used for sliding parts such as gears or bearings, and blades of electric shavers or hair clippers.

Abstract:
A system for communicating data between two control units each capable of executing independent operations and having a memory for operations, the system is provided with a new data generator on one control unit. The new data generator generates new data for a selected item of the other control unit. The new data is combined with address data corresponding to the selected item of the memory of the other control unit to generate transmission data. The transmission data is sent to the other control unit and the new item data is written on the memory at the address specified by the transmission data. The data communication system communicates between the two control units data for a first kind of operations and data for a second kind of operations selectively. The first kind data is communicated repeatedly while the second kind data is communicated a single time.

Abstract:
A silver base electrical contact material with superior resistance to arc erosion along with improved wear and welding resistance. The contact material consists essentially of 0.5 to 39.9 wt % of nickel, 0.14 to 7.0 wt % of nickel oxides, and balance silver. The material contains not less than 0.4 wt % of nickel responsible for constituting minute nickel and nickel particles which have a particle size of not more than 1 .mu.m and are dispersed in a silver matrix for strengthening the material to give improved wear and welding resistance. The dispersed minute nickel oxide particles are included to stabilize arcing occurring at the time of opening and closing contacts in such a manner as to anchor one end of an arc substantially at any immediately available point over the entire contact surface as soon as the arcing occurs, thereby preventing the arc end from moving violently across or beyond the contact surface and therefore minimizing arc related damages or arc erosion. The contact material is made in accordance with a novel method which can disperse the minute nickel and nickel oxide particles in adequate quantities and eliminate the inclusion of undesired bulk and coarse nickel particles which would otherwise deteriorate the contact properties.
