Title: Manufacture of magnetic head
Inventor: MATONO NAOTO
IPC: G11B5/23
Filed: 1985-02-18
Abstract: PURPOSE:To dissolve a step difference of a gap part and a swelling of a spot weld zone, etc., and to improve the yield by obtaining a butt pressure and a push pressure by utilizing a magnetic attracting force, and executing a spot welding by a laser beam. CONSTITUTION:A suitable current is conducted electrically to coils 11, 11, and as a result, magnetic fluxes phi1, phi2 are generated. By the magnetic flux phi1 passing through a butt surface containing a gap 3, a magnetic attracting force is generated on the butt surface of core half bodies 1a, 1b, and this attracting force is about 2g. The magnetic fluxes phi, phi2 pass through the inside of the core half bodies 1a, 1b from a plane base 8 and go into the plane base 8 again, but the magnetic attracting force is generated on a contact surface of the plane base 8 and the core half bodies 1a, 1b, as well and the attracting force of the latter becomes a push pressure. In this way, a spot welding is executed by irradiating a laser beam 6 to a prescribed part, in a state that a butt and push state utilizing the magnetic attracting force has been embodied.

Filed: 1985-02-20
Abstract: PURPOSE:To elevate the measuring accuracy of the degree of weathering, by determining a reference fluidity curve from a reflectance distribution of vitrinite and the amount of inert components in coal to be compared to an actually measured fluidity curve. CONSTITUTION:First, relationship curves 1-4 are determined between the average reflectance of vitrinite and the amount of inert components in various unit coals and the max. fluidity, softening start temperature, max. fluidity temperature and solidification temperature in a gieseler's plastometer.

The max. fluidity, softening start temperature, max. fluidity tempera ture and solidification temperature are determined for each reflectance division from the curves 1-4 as given when the total inert components are zero. Then, the fluidity curve 5 is approximated using a triangle or figures of curves higher than the second order and the fluidity curve 6 obtained for each reflectance division is enhanced by the division-wise content of vitrite. Furthermore, a reference fluidity curve 7 of the subject coal is determined from the curve 6 and the amount of inert components and thus, the degree of wethering is decided by comparing the curve 7 to the actually measured fluidity curve.

Title: Device and method for decoding, and storage medium
Inventor: KOIKE SHOJI
IPC: G06F3/12
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To obtain a smooth dot pattern fast by finding the number of change points from an encoded line code and calculating a coordinate position, and performing expansion with an enlargement multiple corresponding to the variation quantity. SOLUTION: A bit-map expanded pattern is scanned in a specific direction and all code data and the number of all lines corresponding to it are read out of an intermediate data memory 7 to a work area in a RAM 5. A CPU 3 clears all line tables in the work area and reads line codes out in order to store an increase or decrease of edges in a table in the RAM. The start codes of black dots and white dots to be expanded are calculated from the number of decoded edges and edge positions of respective lines after enlargement are stored. After all the lines are processed, a bit-map expanded pattern is generated in the RAM 5 and the decoding process is completed. Consequently, the edge position of a current line can be held not in the RAM, but in a register of a CPU or SRAM, so that the processing is completed in a short time.
