Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To improve the decoding accuracy and to accelerate decoding processing by decoding a data stream bit by bit each time of one-step trace back with a fixed state determined by the value of a tail bit as an origin state. SOLUTION: Before ACS operation reaches a number X of convolved data except for the tail bit, a viterbi decoder 37 decodes data bit by bit, while successively performing the trace back just for a path memory length with the maximum likelihood state which has the least value of path metric as an origin. Before the ACS operation reaches the final ACS operation, data are decoded bit by bit each time the trace back for the path memory length is finished, while successively performing the trace back just by the path memory length with the maximum likelihood state selected out of state candidates determined by the tail bit as the origin. When the ACS operation reaches the final ACS operation of a reception symbol D26, data are decoded bit by bit each time one-step trace back is performed with a specified state 00 as the origin.

Title: Method for monitoring slag bath depth
Inventor: FUJIYAMA HIROHISA
IPC: B23K25/00
Filed: 1985-04-03
Abstract: PURPOSE:To prevent the decrease in the depth of a slag bath and to obtain a defectless welded joint by detecting the abnormal oscillation generated when the depth of the slag bath decreases in excess of an adequate value range or the oscillation of a molten pool by a small explosion. CONSTITUTION:The voltage proportional to the magnitude of the oscillation is outputted from a detector 1 when the depth of the slag bath decreases in excess of the adequate value range and when the small explosion or abnormal oscillation arises. The voltage is amplified by an amplifier 2 and is then inputted to a filter 3 for taking out only the desired signal. The output from the filter 3 is compared with the output from a reference voltage generating circuit 4 in a comparator circuit 5 and the output signal is outputted only when the level of the abnormal signal is higher than the reference voltage level. The outputted voltage is amplified by an amplifier 6 and operates an alarm lamp 7. The depth of the slag bath is immediately restored to the adquate value range when the welder feeds the flux into the molten pool immediately when the lamp 7 operates. The welding is thus made normal.

Filed: 1990-03-20
Abstract: PURPOSE:To develop a rolling bearing sufficiently usable in a wide temperature range from room temperature to high temperature by using material obtained by pressure- molding, and sintering complex raw material composed of boron carbide and mesophase carbon sphaerites. CONSTITUTION:B4C powder used mainly as boron carbide is mixed with carbon material and made into a complex by high temperature baking after being molded. An optically anisotropic carbonaceous globule known also as the name of a mesophase carbon sphaerite is globular and manufactured by pitch heat treatment. Pulverization is performed by shock, abrasion, jet grinding, or the like. The mixed powder is molded by a hydraulic press or the like, and the molded body is subjected to temperature rise in coke breeze under the non-oxidizing gas atmosphere. After removing the volatile part, the molded body is cooled under the non-oxidizing gas atmosphere so as to be formed into a pre-burned product, and the pre-burned product is subjected to heat treatment under the inactive gas atmosphere or under reduced pressure to become a burned body. The thus obtained carbon-boron carbide sintered body is of high strength and also excellent in heat resistant impulse, oxidation resistance and machinability.
