  • Patent number: 5813691
    Abstract: A twist beam type suspension has a twist beam having an increased rigidity. Each of a pair of trailing arms has a front end pivotally mounted on a body of the vehicle and a rear end rotatably supporting a wheel. A twist beam extends between the trailing arms in a side-to-side direction of the vehicle. Opposite ends of the twist beam are connected to the respective trailing arms. The twist beam has a bent portion projecting upwardly in the center of the twist beam.

  • Patent number: 5766375
    Abstract: A non-oriented magnetic steel sheet having excellent bending workability and magnetic characteristics is obtained by continuous annealing. The non-oriented magnetic steel sheet is obtained by the method comprising cold rolling a hot-rolled steel sheet, continuously annealing the steel sheet, and then performing skin pass rolling; the steel has a composition comprising about 0.005 mass % or less of C, about 0.05 to 0.30 mass % of Si, about 0.10 to 0.50 mass % of Mn, about 0.15 to 0.50 mass % of Al, and about 0.0050 mass % or less of N.

  • Patent number: 5699171
    Abstract: A facsimile machine including a data obtaining device which obtains a plurality of sets of own-call-number data each set of which identifies a corresponding one of a plurality of different own call numbers allotted to the facsimile machine according to a common numbering rule, each of the different own call numbers identifying the facsimile machine from other facsimile machines to which other call numbers different from the own call numbers are allotted according to the common numbering rule, a plurality of memories which are related with the different own call numbers, respectively, and in which a plurality of batches of information are stored, respectively, and a transmitter which transmits, to one of the other facsimile machines, the batch of information stored in one of the memories which corresponds to one of the different own call numbers identified by one of the sets of own-call-number data obtained by the data obtaining device.

  • Patent number: 5288966
    Abstract: A cutting mechanism for use in an electrical discharge cutting machine that has a frame mounting a wire electrode cutter, a pair of rollers to feeder the wire electrode and a sensor for detecting the presence of the wire electrode. The frame can be moved from side-to-side so that it may be positioned to feed the wire electrode to a machining zone or to a disposal box when a portion of the wire electrode is to be cut off following a breakage of the wire electrode.

  • Patent number: 5268551
    Abstract: While a workpiece is processed, a wire electrode is fed in the first direction by a drive roller from a wire bobbin energized in the second direction which is the reverse direction of the first direction. A brake roller installed between the wire bobbin and the drive roller supplies the wire electrode installed between the wire bobbin and the drive roller with additional tension. If the wire electrode is broken, the wire bobbin winds up the broken wire electrode. A wire end detecting sensor detects the end of the broken wire electrode when the wire electrode is wound up so that the end of the wire is stopped at a predetermined position.
