Abstract: PURPOSE: To enhance mechanical strength, particularly, elasticity of a structure layer, and to reduce an abrasion rate of a friction layer by including the structure layer consisting of a composite carbon-carbon material and a friction coating of a composite carbon-carbon material for covering one surface by being fixed to at least one surface of the structure layer. CONSTITUTION: A structure layer 1 is formed of a fibrous material of the so- called 'coarse' texture 5g including rovings of carbon fiber or a carbon fiber precursor and having an average hole diameter exceeding 100 μm. A friction layer 2 is formed of a fibrous material of the so-called 'fine' texture 5f including irregularly distributed carbon or a carbon precursor and having an average hole diameter less than 50 μm. The length of a roving segment is 5 to 60 mm, and the length of a fiber segment is 0.05 to 60 mm.

Title: Control method for power steering unit
Inventor: OKADA KUNIO
IPC: B62D6/02
Filed: 1986-06-11
Abstract: PURPOSE:To eliminate the precipitous feeling which effects during large angle steering operation, by making the output of a steering angle PS device inversely proportional to the steering angle of a vehicle when the vehicle speed exceeds a predetermined value and the steering angle is below a certain angle, and by making the output of the steering angle PS device proportional to the steering angle when the steering angle exceeds the certain angle. CONSTITUTION:When the vehicle speed exceeds a predetermined value such as, for example, 30km/hr, data taken on registers, 4, 5 have less values as the steering angle increases up to a steering angle theta1. At this time a polarity reversing unit 8 delivers an input data thereof as it is since the output of a subtractor 6 is in the direction in which the steering angle increases, and is therefore positive. Accordingly, a subtracter 9 subtracts the result of computation by the subtracter 6 from a value read out from a ROM 3 one clock pulse before. Further, a multiplier 10 converts the value into a solenoid current, and therefore, the output of the PS device is inversely proportional to the steering angle until the steering angle increases to the value of theta1 when the vehicle speed exceeds 30km/hr.

Title: Memory access control system
Inventor: KOREKATA KENJI
IPC: G06F15/17
Filed: 1988-05-31
Abstract: PURPOSE:To prevent the deterioration of the throughput of an access source having a high throughput by inhibiting the access request given from an access source having a low throughput via a preference selection means and sending the access request received from the access source of a high throughput to a main memory with preference. CONSTITUTION:When a conflict is caused between the continuous block accesses given from both access sources B and A, a conflict detecting means 4 produces the conflict detection output. This output is supplied to a preference selection means 5. The means 5 receives said output and inhibits the access request received from the source B having a low throughput at occurrence of a conflict. Then the means 5 produces a control signal to select the access request of the source A having a high throughput. Thus it is possible to control the conflict so as to avoid the deterioration of the throughput of an access source having a high throughput even in case a conflict occurs between the continuous block accesses of two access sources having different through puts.

Title: Rolling bearing and rolling element therefor
Inventor: GABELLI ANTONIO
IPC: F16C33/32
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To relieve the influence of impressions generated on the raceway surface or the surface of a rolling element so as to improve wear resistance and contamination resistance of a bearing by forming part of a plurality of rolling elements of zirconium material higher in hardness or rigidity than other rolling elements. SOLUTION: When a rolling element is rolled on an outer ring 6, impressions with small recessed parts 4 and protruding edge parts are formed by solid contaminant particles existing on the raceway surface. Rolling elements formed of zirconium material higher in hardness or rigidity than other rolling elements out of a plurality of rolling elements are therefore rolled on the impressions. Then the protruding edge parts are crushed to form a raised part 7 of a level corresponding to the undamaged surface 8 of the outer ring 6 so as to be able to recover a smooth characteristic on the raceway surface. Only the small recessed parts 4 remain but do not adversely affect the operating characteristic of a bearing and on the contrary helps lubrication of the rolling elements. The generation of cracks and friction is therefore suppressed and the operation or the bearing becomes silent.

Title: Zinc-chromium composite plated steel sheet excellent in spot weldability
Inventor: MATSUDA HIROSHI
IPC: C25D5/26
Filed: 1995-05-31
Abstract: PURPOSE: To provide a stable and prolonged electrode life and a plated steel sheet without performing complicated treatments, such as addition of iron group elements, etc., and multilayer formation, by lowering Cr concentration in a plating layer at a specific depth. CONSTITUTION: In a Zn-Cr composite plated steel sheet having a Zn-Cr plating film, Cr concentration in the surface layer part, between the surface of the plating film and a position at a depth of <0.5μm from the surface, is regulated to <1wt.% (including the case of zero). In the case where Cr oxides exist in the surface layer of the plating film, the electrification passage between the electrode and the plating layer at spot welding is limited by the oxides and, as a result, excessive heating is brought about between the electrode and the plating layer and spark and deposition occur and electrode life is decreased.  Accordingly, the regulating Cr concentration in the surface layer part between the surface of the plating film and a position at a depth of <0.5μm from the surface to <1wt.%, a stable and prolonged electrode life can be obtained and also the Zn-Cr composite plated steel sheet causing neither spark nor deposition at the time of welding and having excellent spot weldability can be obtained.
