Title: Signal processing device, position detecting device and driving device
Inventor: TAKEISHI HIROAKI
IPC: H03M1/64
Filed: 1994-02-18
Abstract: PURPOSE:To prevent the mis-matching of the information and generation of errors, and improve the reliability and the accuracy of measurement by generating the interpolated signal of high resolution from the sine and cosine two-phase signals, counting the number of the fundamental wave periodicity for synthesizing, and correcting the relative error of the respective phase (position) information. CONSTITUTION:The A/D conversion 5 of the sine and cosine signals from an encoder 5 is realized and the converted signals are outputted as SINX and COSX of 12 bits. At the same time, the sine and cosine signals are inputted into a phase digitizer 2, and the digital data M of three bits are outputted. A high speed signal processing part 3 receives the output M and outputs the periodicity N of the sine wave signal and the logical signal PH. The DSP 4 generates the positional information using the inputted signal. First, the phase angle phi of the sine wave signal is obtained, and the judgement of mis-match is made if the phase angle phi is between 0 and 180 deg., and the logical signal PH is 0, and the periodicity N is increased by 1 to be corrected. This constitution prevents the mis-match between the data to be processed and eliminates the detected instantaneous errors.

Title: Gas lighter
Inventor: HONDA HIROHIDE
IPC: F23Q2/28
Filed: 1986-02-03
Abstract: PURPOSE:To improve ignitionability of a gas lighter, by matching a burner port to the upper edge of a cylindrical wall which is formed to surround a nozzle, excluding the side where a discharge electrode is disposed, by forming an inclined wall over the discharge electrode, inclining to the burner port, and by providing an air slot on one side of a cylindrical wall. CONSTITUTION:A combustion chamber 16 is formed by partitioning off part of a space inside a cylindrical wall 15 which is formed to surround a burner nozzle 10, excluding the side containing a primary combustion zone 14. The upper edge of a wall 15 is matched to a burner port 17, as the diameter of an edge is formed as the same as that of a burner port 17. The upper part of a wall above a discharge electrode 13, facing to the side containing the primary combustion zone 14, is formed into an inclined wall 18, which is inclined to the burner port 17. The extra sub-gas going up from the primary combustion zone 14 is discharged to the outside, joining the flowing direction of a main gas 19 flowing from the burner nozzle 10. Accordingly, good mixed gas is formed in the primary combustion zone 14. Besides an air slot 21 is formed on one side in the lower part of a wall 15. The air slot 21 helps suction and discharge of air to be performed smoothly, by purging the residual gas caused by a turbulence produced in the combustion chamber 16.

Title: Electron beam welding method
Inventor: TAMURA KOUJI
IPC: B23K15/00
Filed: 1980-02-25
Abstract: PURPOSE: To obtain a defect-free cratr by oscillating an electron beam in a circular shape at the time of decreasing the electron beam output by stopping the movement of the materials to be welded or an electron gun, that is, the movement of the irradiation spot of the electron beam.  
     CONSTITUTION: While the materials 3A, 3B to be welded are being rotated, an electron beam 4 is irradiated from the welding start part to the welding part and is reached to the welding start part by making a round. Welding is performed again by passing the beam twice perfectly through the start part and after the rotation of the materials 3A, 3B to be welded is stopped, the beam output of the electron beam 4 is gradually decreased. At this same instant, the beam 4 is oscillated in a circular shape, and a core wire 7 contg. Mn is fed to molten metal 6 to mix the melt of the core wire 7 into the molten metal 6, whereby the welding is completed. According to this method, the weld defects such as lack of fusion and cavities which are likely to be formed in the toe of penetration of welding are prevented; also, the temp gradient by welding is decreased and the occurrence of bead cracking and cracter cracking are prevented.

Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent a wire from being cut or damaged and at the same time, even when an error in carrying in/out a work occurs during carrying in/out the work with a work support mechanism and at the same time, make sure that the work is manually carried in/out safely even during the traveling of the wire by shielding the part, facing the work, of a row of wires using a cover. SOLUTION: A plain platelike cover 22 consisting of two split cover segments 22a is hinged 23, in an opening/closing rotatable manner, on the upper end parts of paired support frames 14, above a row of wires 18 between plural fabrication rollers 15-17. When a work 21 is carried in/out between a work support mechanism 20 and the outside, both cover segments 22a are rotated to a horizontal closing position and the overhead part of the row of wires 18 is closed. Consequently, even when an error in carrying in/out the work 21 with the work support mechanism 20 occurs, the falling work 21 is received by the cover segments 22a to be securely held. As a result, the work 21 is prevented from falling directly onto the row of wires 18 and thus the damage of the work 21 and the cut of the row of wires 18 are avoided before such accidents would happen.
