Title: Coppery sintered friction material and its production
Inventor: ISHIBASHI KEIJI
IPC: B22F3/105
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To increase a coefficient of friction and to improve wear resistance by regulating the porosity of a sintered friction material, prepared by solidifying a raw- material powder composed essentially of copper, to a value in a specific range. SOLUTION: The porosity of the coppery sintered friction material is regulated to 35 to 60%. By this method, the increase in a friction coefficient can be made effective by the permeation of lubricating oil existing in the contact interface between a friction material and a mating material and the increase of contact area due to reduction in rigidity. This material has hard grains and a copper alloy matrix as the balance of them, and the hard grains are contained by 5 to 40% by weight and the copper alloy matrix as the balance has copper or copper alloy, lubricant, and inevitable impurities. As the hard grains, a ferrous intermetallic compound is particularly preferred from the view point of an increase in friction coefficient and excellent machinability. Further, it is preferable to regulate the average grain size of the hard grains to <=20 μm.  Material powders are mixed into a prescribed composition, and the resultant powder mixture is press-compacted in a die and also pressurized under electrification, and the resultant sintered compact is heat treated at 700 to 1,000 deg.C.

Filed: 1985-10-25
Abstract: PURPOSE:To prevent a correctable small dropout from being treated as a faulty product, by performing signal reproducing operations before data are recorded on an optical disk and detecting the part where levels of reproduced signals exceed a set range as a dropout. CONSTITUTION:A signal read out by means of a pickup 1 from an optical disk 12 is amplified by a preamplifier 2 and converted into a digital signal by a data slicer 3.

The output of the preamplifier 2 is converted into digital signals by slicing the output at a high level (a) and low level (b) by using level slicers 5 and 6 and a signal C is outputted through an OR gate 8. The signal C is gated by the gate signal B at an AND gate 9. A signal D outputted from the AND gate 9 becomes a signal which indicates a dropout only to the additional area.

Title: Heat treating method for metal powder and metallic thin strip and treated metallic body
Inventor: NISHIKAWA SHUNICHIRO
IPC: B22F1/00
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent the oxidation of powder or a thin strip in heat treatment by controlling the mimimum side of a vessel filled with powder or a thin strip to the value equal to or below the specified one and also controlling the ratio of the interface area of an atmosphere to the filling volume thereof to the value equal to or below the specified one. SOLUTION: In a material with the shape of powder, a thin strip or a thin piece, the conduction of heat between grains is inferior, and for making the temp. of the whole into the uniform one, much time is required. Therefore, there is a need of reducing the distance in which heat conducts between the metals by filling the material into a thin vessel, and the mimimum side of the vessel is controlled to <=0.4 m. Moreover, an alloy containing rare earth elements and active metals such as Ti is prone to form a compound with oxygen, and as to the shape having a large specific surface area, e.g. of powder, a thin strip or the like, the tendency is remakable thereby deterioration in the characteristics thereof is caused by heat treatment.  Thus, the ratio of the interface area of the atmosphere to the volume in the case of being filled with the powder, thin strip or the like is controlled to <=10.0 (l/m), so that the production of oxide on the metallic surface is reduced.
