  • Patent number: 5472076
    Abstract: Two cooperating spiral conveyors are provided between a transport device having a transport plane and a transport segment. The conveyors are driven in opposite directions and are provided with opposite thread directions. The axes of the spiral conveyors are disposed at the height of the transport plane. The pitch and the thread clearance of peripheral recesses of the spiral conveyors decrease continuously from the transport device to the transport segment. A support surface for a lid is disposed between the two spiral conveyors. At the end contiguous to the transport device, the support surface has the same height as the transport plane, and at the end contiguous to the transport segment, its height is lower by half of the lid diameter.

  • Patent number: 5473529
    Abstract: In accordance with the present invention, two unsymmetrical differential amplifier stages are fed from a common signal source that supplies an AC voltage signal, but to which the two differential amplifier stages are connected with respect to the unsymmetry in opposite senses. The outputs of the two differential amplifier stages, however, are connected with respect to the unsymmetry in like sense and to an output circuit that provides the load resistances and whose output supplies the rectified a.c. voltage signal that also has an approximately quadratic characteristic.

  • Patent number: 5471360
    Abstract: A DC electromagnet apparatus that can prevent an excessive making coil current caused by changes in a power supply voltage. The electromagnet has an operation coil, a switching device, and a current detecting resistor connected in series. A one-shot pulse generating circuit produces a one-shot pulse having a pulse width corresponding to the duration of the making coil current flowing through the operation coil to close the electromagnet. A Miller circuit generates, based on the one-shot pulse, a trapezoidal pulse having a predetermined rising rate, a predetermined peak value, and a pulse width substantially equal to that of the one-shot pulse. A comparator produces an ON control signal that controls the switching device in such a manner that the making coil current becomes proportional to the trapezoidal pulse.

    Abstract: A write once type information recording medium having a recording format that includes sectors. Each Sector includes x pieces of p-bit frames. Each frame contains an f-bit synchronization signal region and a d-bit data region. Each bit of at least one x-bit packet in which a v-bit error correction code has been added to u-bit data, is distributed to each one of the data regions of the x pieces of frames. This makes it possible for the write once type information recording medium to have an increased data storage efficiency and an effective error correction capability for a burst error.

  • Patent number: 5469323
    Abstract: A method and apparatus for trapping charged particles employs at least one central electrode. An AC voltage and a DC voltage are superimposed and are applied to the central electrode resulting in an AC electric field having an intensity which declines with an increase in the distance from the central electrode, and a DC electric field which attracts charged particles forces toward the central electrodes. Charge particles are trapped in the space outside the central electrode by these fields. A wide trapping range in terms of mass and energy can be achieved with a high trapping density. The central electrode can consist of four element electrodes which are supplied with AC voltages superimposed on a DC bias voltage in such a manner that respective adjacent element electrodes are supplied with opposite phase AC voltages.
