  • Patent number: 5611656
    Abstract: A linkage arrangement for guiding and manipulating a work implement, such as a bucket, includes a V-shaped guide link and a curved implement link. A plurality of pin joints connect the implement link to the bucket, the guide link, and to a fluid cylinder. The fluid cylinder, the guide link, and the implement link cooperate to rotate the bucket between open and closed positions, for digging and carrying materials. The linkage arrangement provides high forces for digging and bucket rotation and desirable lower rotational velocity for clamping object in the fully closed position.

  • Patent number: 5464751
    Abstract: A purified proteinaceous substance bindable with p185, the translation product of the neu oncogene is disclosed. The purified proteinaceous substance may be characterized in that it increases the activity of the tyrosine kinase contained in the neu oncogene product but does not increase the activity of tyrosine kinase of epidermal growth factor receptor; induces p185 dimerization and internalization; affects the growth of cells which express p185 in a dose dependent manner; is heat stable from about 56.degree. C. to about 100.degree. C.; is degradable by protease; and has a molecular weight of from about 7,000 to about 14,000 daltons in its smallest active form as determined by gel filtration and ultrafiltration membrane analysis. Methods of detecting p185 on the surfaces of tumor cells are also disclosed.

  • Patent number: 5426452
    Abstract: A laser imaging apparatus includes a laser diode which is controlled to produce a laser beam the power of which varies linearly as a function of a digital image input signal. The laser beam is deflected by scanning optics to expose photosensitive media such as film. When the digital image input signal is in a first range of values to operate the laser diode in its linear region, the laser diode is controlled to operate in an amplitude modulation mode. When the digital image input signal is in a second, lower, range of values which would operate the laser diode in its non-linear operating region, the laser diode is controlled to operate in the linear region but in a pulse amplitude modulation mode.

  • Patent number: 5276697
    Abstract: A laser imaging system includes a laser diode and an automatic power control circuit with a laser diode protection circuit. The protection circuit includes a shunt circuit for shunting power around the laser diode in response to one or more of the following conditions: laser light power over a predetermined maximum value, temperature of the laser diode is below or above a predetermined temperature range, the electrical power supply is below or above predetermined voltage values during power up and power down.

  • Patent number: 5260955
    Abstract: A technique for automatically setting a threshold current for a laser diode which has a linear laser operating region and a lower non-linear operating region. The laser diode is controlled (1) during a warm-up period during which no operating current is supplied to the laser diode, to allow the electronics and laser diode to stabilize; (2) during an initialization period, during which the current through the laser diode is brought up to a threshold operating point above said non-linear operating region and during which no image data is applied to the laser diode; and (3) during an operating period in which digital image data is applied to the laser diode to operate it in the linear laser operating region.

  • Patent number: 5197076
    Abstract: Laser apparatus containing an electrically operated laser (laser diode) is temperature stabilized so that it is able to generate a beam of laser light of sufficient intensity to be suitable for use in a laser printer without entering a failure mode due to overheating. The laser diode is integrated into a hybrid thick film integrated circuit wherein the laser diode is bonded to one side of the hybrid's substrate of thermally conductive and electrically insulating material of the hybrid. The hybrid has conductors thereon which are connected to the leads from the laser diode. A circuit containing temperature sensitive material (elements formed of positive or negative temperature co-efficient resistive material) is distributed in spaced areas on the opposite side of the hybrid's substrate from the laser diode. The distributed thermistor circuit and its close thermal coupling to the cooler and the diode laser reduce thermal mass (capacitance), which must be heated or cooled, to maintain athermal conditions.

  • Patent number: 4781119
    Abstract: A solar-powered rapid transit system is provided, which travels suspended above ground along a horizontal rail, supported by vertical/horizontal supports. The guide rail is basically a parallelogram, with five inner surfaces. It can be configured as either an overhead monorail system, or a birail system. The rail car is attached to and suspended from such rail by power transmission and support shafts, each of which attaches to a wheel box that fits into the horizontal guide rail. Power is transmitted to the wheels in each wheel box from several electric motors by a series of pulleys and belts in a unique configuration. Such wheels then propel the rail car or cars, which can be connected in series, down the rail. Power for electric motors is supplied by rectangular solar panels supported by vertical supports attached to the roof of each rail car, which extend several feet above the rail car and guide rails.

  • Patent number: 4774710
    Abstract: A controller for a laser diode causes the diode to generate an illuminative output which varies linearly in response to changes in image signals which range between minimum and maximum brightness levels. A switchover point between first and second modes of operation is selected to be above the knee region of the laser diode operating curve. If the input signal values are above the switchover point, diode illuminative output is a function of these signal values. However, if the input signal values are below the switchover point, then the input signals are modulated to switch the diode several times between an "on" state which is above the knee region and an "off" state, to form one picture element (pixel). In order to vary the illuminative output as a linear function of the change in image signal level, the diode "on" time during formation of one pixel is a function of the image signal value.
