Title: Silicone-covered roll and method for its production
Inventor: SHIMIZU KOJI
IPC: B29D99/00
Filed: 1987-12-30
Granted: 1992-06-02
Abstract: Abstract of the Disclosure This invention provides a silicone elastomer-covered roll consisting essentially of a central roll axle that is in contact with an inner layer of cured silicone elastomer having a hardness value no greater than 30 on the JIS A scale and an outer layer of cured silicone material having a hardness in excess of that of the inner layer.  The roll is resistant to assuming a permanent compression set during use, in addition to exhibiting excellent soiling resistance.  In particular, when used as a fixing roll in an electrophotographic copier, the contact area with the hard roll can increase, resulting in a clear image on the copy paper.

Title: Filter with valve-in-head construction
Inventor: SCHUMACHER ROBERT G II
IPC: B01D35/153
Filed: 1988-01-11
Granted: 1993-01-12
Abstract: ABSTRACT           A valve-in-head filter includes an outer housing (2) adapted to receive a fluid filter cartridge (4) therein.  A valve head (7) is provided which includes an annular stand pipe (22) for locating an end of the filter.  The stand pipe is cut away (32) on its downstream side to reduce fluid back pressure. Furthermore, a passage (13) is disposed between the head inlet (11) and outlet (12), with the passage receiving a slideable plunger (23) therein.  A manually actuatable handle (28) connects through a rotary actuator (29) to move the plunger. The actuator includes a stem (30) mounted eccentrically to the handle axis, with the stem received in a recess (31) in the plunger so that turning of the handle moves the plunger between "on" and "off" positions.  The plunger includes a seal (26) which continuously engages the passage wall in all plunger positions, and the construction provides full "on" and "off", with no fluid bypass in the "off" position.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus for setting an underwater conduc-tor pipe, in which the conductor pipe is lowered into the wellhole on a drill string as the borehole  is being formed by a drill bit and underreamer positioned at the end of the drill string below the end of the conductor pipe.  The drill string and conductor pipe are detachably interconnected by a housing latch which includes means for detachably securing the drill string and drilling assembly to the conductor pipe.  The drill string is provided with an upper latch sub, which retains and supports the drill string in its fully extended position within the conductor pipe, and a lower latch sub which retains and supports the drill string in the re-tracted position.  As the apparatus is lowered a drill motor actuates the drilling assembly such that the well hole is formed in the ocean floor.  Drilling continues until the permanent guide base of the conductor pipe engages the ocean floor.  Thereafter, the upper latch sub is released and the drill string is retracted until the lower latch engages the latchhousing.  The outer annulus of the conductor pipe is then cemented into place while pressure within the conductor pipe is maintained to prevent the cement from travelling up the inside of the conductor pipe.  Once the cement is set, the latchhousing is released so that the drill string and latchhousing can be removed from the conductor pipe.

Title: Automatic weight detecting device
Inventor: MIHARA MAKOTO
IPC: G01G7/06
Filed: 1988-07-12
Granted: 1992-06-09
Abstract: Abstract:    An automatic weight detecting device for use in an electronic oven is provided with a platform on which an object to be measured is placed.  A shaft supports the platform and is both rotatable and slidable vertically. A resilient member supports the shaft.  A load detecting device converts the weight of the object into an electrical amount, e.g. a capacitance, and a weight detecting circuit integrates the readings to obtain the average of the electrically physical amount while the platform is rotating.  The result is improved accuracy and less fluctuation of the instantaneous weight as the platform rotates.

Title: Optical transmitter driver with current peaking
Inventor: CAVANNA VICENTE V
IPC: H04B10/43
Filed: 1988-07-14
Granted: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURES    A driver for an electro-optical transducer, such as a light-emitting diode (LED) is disclosed which shapes current pulses so as to contain "spikes" during turn-on and turn-off in order to quickly charge and discharge the junction and stray capacitances of the LED.          Degeneration resistors interconnect the emitters of switching transistors used in a differential amplifier supplying the current to the LED and in a differential amplifier supplying a "peaking" current to the switching amplifier.  A capacitor couples the amplifiers to conduct the additional current to the LED when it is initially turned on and charges the cathode of the LED.          The emitter degeneration resistors couple the amplifiers to current sources and allow the amplifiers to be driven by emitter-coupled logic (ECL) gates without ringing.          The resistors also linearize the transfer functions of the amplifiers so that the voltage swing of the ECL driver does not overly turn-off the transistors within the amplifiers, thereby improving response time.

Granted: 1995-05-16
Abstract: A liquid-crystal display, preferably twenty-five lines of eighty characters each, is mounted in a case.  The temperature of the display medium is maintained within operating limits for the display -- notwithstanding ambient temperature and humidity variations over generally normal ranges for at least the temperate zones, and even if the display unit is placed to receive direct sunlight.  The unit works outdoors as well as in buildings that lack temperature control.  This is accomplished preferably by circulating air from outside the case through a space between the display face and an unperforated protective polycarbonate window.  Intake and exhaust plena are long and narrow enough to deter manual access to the display and thus vandalism; however, the plena are straight and sufficiently free of obstruction that the fan can be a very small, low-power, quiet unit.  A temperature sensor controls the fan, and also the contrast-adjusting voltage of the display -- base on data in a digital-memory "look up" table.  A heater is preferably provided, also temperature-controlled.  The plena face downward so that the unit is not sensitive to rain, and the entire unit can be flush-mounted in a wall without disrupting system cooling.  Visible glare arising in reflection at the window is reduced by an antireflection coating on the window.
