Abstract: A digital-to-analog converter for generating output waveforms with less distortion without the need for high-speed components. The digital-to-analog converter comprises a D/A converter, four voltage holding sections, four step function waveform generators, a voltage summing section, two integrators and a timing controller. The voltages corresponding to four sequential digital data inputs are held in the voltage holding sections, respectively, and the step function generators generate step function waveforms at the voltage levels corresponding to the held voltages. The voltage summing section combines the step function waveforms generated in the step function waveform generators, and two integrators integrate this combined waveform two times, thus producing a continuous analog voltage composed of the input digital data.

Abstract: A method for preparing a colorful sole for a shoe, which laminates a membrane with patterns on the sole. The membrane is made of a polymer to merge with the sole to firmly combine with the sole. Additionally, the patterns are printed on the membrane, thus the patterns can be complicated and special to make a variety of changes in appearance to the colorful sole.

Abstract: A hypocycloid drive device for adjusting slat angles of a venetian blind includes a housing, a roller, a hypocycloid drive reducer, a tilt cord and a tilt rod. The roller is rotatably mounted in the housing and is rotated by pulling the tilt cord. The hypocycloid drive reducer is coupled to the roller and is used to reduce an angular speed of and rotate the tilt rod. The tilt rod is adapted to change slat angles of the venetian blind. Consequently, volume of the hypocycloid drive device is minimized to accommodate convenient installation of the hypocycloid drive device.

Abstract: A data interpolating system by which the operating quantity can be decreased and no truncation error is produced. A data processor comprises a discrete value extracting section 10, a sampling function operating section 20, and a convolution operating section 30 so as to perform interpolation between discrete values. The discrete value extracting section 10 extracts just previous four value from successively inputted discrete data, and the sampling function operating section 20 calculates, when the data interpolating position is specified, the value of the interpolating position based on the distances between the data interpolating position and the discrete values by using a sampling function of local support which can be differentiated only once over the whole region. The convolution operating section 30 multiplies the values of the four sampling functions by the discrete values, and adds up the products, thus performing convolution operation and outputting the interpolation value.

Abstract: A traveling wave tube includes a glass or other insulating envelope having a plurality of substantially parallel glass rods supported therewithin which in turn support an electron gun, a collector and an intermediate slow wave structure. The slow wave structure itself provides electrostatic focussing of a central electron beam thereby eliminating the need for focussing magnetics and materially decreasing the cost of construction as well as enabling miniaturization. The slow wave structure advantageously includes cavities along the electron beam through which the r.f. energy is propagated, or a double, interleaved ring loop structure supported by dielectric fins within a ground plane cylinder disposed coaxially within the glass envelope.

Abstract: A hinge for a notebook computer is composed of an upper seat, a lower seat, and two arms. The upper seat is rotatably mounted in the lower seat, and the arms are mounted on the upper seat. A monitor of the computer is installed on the arms, and the lower seat is secured on a body of the computer. Therefore, the monitor can be turned about the arms to raise from the body, and turned along with the upper seat about a vertical axis of the lower seat to adjust a visible scope.

Abstract: The invention provides a two-stage laser mode of photolithographic molecular fluorine laser system for matching the center wavelength of an oscillation-stage laser to the center wavelength of an amplification-stage laser, thereby oscillating a laser beam having a low spectral purity and a narrow linewidth. The laser system is of the two-stage mode comprising an oscillation-stage laser 10 and an amplification-stage mode 20. The center wavelength of a laser beam emitted out of the oscillation-stage laser 10 is compared with and substantially matched to the center wavelength of a laser beam emitted out of the amplification-stage laser 20 when the latter is oscillated by itself.

Abstract: A data interpolating method capable of reducing an operation volume without the occurrence of a truncation error. Each of four step function generators generates a preset step function. Multipliers each multiply step function values output from relative step function generators by discrete data values held cyclically in data holding sections. An adding unit adds together the multiplied results output from respective multipliers in response to the respective four discrete data and the added values is integrated twice by integrators, an interpolation value between the discrete data being then output from the second-stage integrator.

The cart body, including a chassis part, a neck part and a steering device part, is formed as an integral hollow piece using the rotational molding method. The wheel system provided under the chassis consists of one front wheel and two rear wheels, with the front wheel being mounted pivotally on a suspension as a free wheel, while the rear wheels are driving wheels using a differential gear device driven by a motor. At the center of the handlebars, which are made of circular rods, a dial-type speed controller is located, and a brake lever is provided under the steering device, together with a lock mechanism.

Abstract: An electrode-less lamp equipment with higher luminance by higher lamp-cooling efficiency wherein the airflow generated by the blower 9 goes through the ventilation hole 12 and spouts out from the open end of the lamp-cooling nozzle 15 and cools the surface of the electrode-less lamp 1 is provided. The velocity of the airflow is accordingly high around the lamp surface enough to efficiently cool the lamp. This makes it possible to raise the input power density to the lamp and to increase luminance.

The battery holder is mounted on the bottom surface of the handle and has a pair of parallel channels that can contain the dovetail keys of the handle. When using the portable electric tool with a mountable bi-directionally battery holder in accordance with the present invention, users can rotate the connecting direction of the battery holder to provide a convenient way in use.

Abstract: A clasp knife is composed of a handle and a blade pivotally mounted on the handle. The handle has a fastening member and a locking member provided therein. The blade has a taper hole, a tongue slot, and a locking surface. When the blade is received in the handle, the fastening member is positioned in the taper hole and the locking member can abut the locking surface of the blade, so that the blade cannot be freely pivoted outwards to extend from the handle without the operation of the user. When the blade is extended, the locking member can be inserted in the tongue slot to prevent the blade from freely pivoting.
