Title: Improvement of delayed fracture resistance of high tensile strength bolt
Inventor: KATO TAKEHIKO
IPC: C21D1/76
Filed: 1990-02-20
Abstract: PURPOSE:To improve the delayed fracture resistance of a high tensile strength bolt by subjecting a bolt prepared by cold-forming a phosphated steel stock to intermediate heat treatment in an oxidizing atmosphere under specific conditions and then to quench-and-temper treatment. CONSTITUTION:Cold forming is applied to a steel stock previously subjected to phosphate treatment aiming lubricating treatment at the time of cold forging is cold-formed into a bolt. At the time of heat-treating this bolt, intermediate heat treatment is carried out under an oxidizing atmosphere under the conditions satisfying relational inequalities, 600<=T<=750 deg.C and t>=0.002T<2>-3.2T+1,290(min), [where T means heating temp. and (t) means holding time at a temp.T). Then the above bolt is subjected to quench-and-temper treatment. Owing to the above intermediate heat treatment, the phosphate film on the bolt can be oxidized and removed, and phosphorizing can be prevented in the subsequent quench-and- temper treatment. By this method, the delayed fracture resistance of the high tensile strength bolt can be improved.

Title: Silver-cadmium oxide type electrical contact material
Inventor: YAMAMOTO HIRONOBU
IPC: C22C5/08
Filed: 1979-04-04
Abstract: PURPOSE: To obtain an electrical contact material having superior fusion bonding resistance and workability and undergoing little abnormal consumption by adding a specified slight amt. of Co to an Ag-Cd-Sn alloy followed by internal oxidation.  
     CONSTITUTION: An alloy consisting of Cd 1W20%, Sn 0.1W5%, Co 0.001W0.5% and the balance Ag is refined by melting Cd and Sn in a graphite crucible and adding Co and Ag in this order followed by melting. This molten alloy is cast, and the resulting ingot is worked into predetermined form and internally oxidized at 750°C under an oxygen partial press. of 3 atm. Thus, the Cd and Sn are selectively oxidized, and the oxides are dispersed in the Ag matrix. The Co added results in grain refining after the internal oxidation, and the oxides are distributed finely and uniformly to give an electrical contact material having superior workability, fusion bonding resistance and consumption resistance.

Title: Image processor and method therefor
Inventor: MATSUMOTO ATSUSHI
IPC: G06T5/00
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To make image data useful for an excellent image formation, suppressing the generation of a pseudo contour, etc., even if a visible image is formed with the image data after a conversion and preserving the density for the whole of the image, when image data of multigradation is converted into the image data of the gradation which is fewer than the multigradation. SOLUTION: In a ROM 5, two thresholds are preliminarily stored to be flacutated and read. When a ternary coding is performed for an 8-bit image data (256 gradation image data), a threshold switching device 104 reads the two thresholds necessary when the ternary coding is performed from the ROM 105 and supplies them to a threshold processor 103. The threshold processor 103 compares the picture element data (the data corrected in an error distribution processor 102) in the inputted image data and the two supplied thresholds and outputs either one of the picture element data for which the ternary coding is performed of 0, 1 and 2. An error arithmetic processor 106 takes the difference of the ternary coding result and the picture element data at the stage before the ternary coding, calculates the error and distributes the error to unprocesed picture element locations.  The above processings are performed one after another.
