Abstract: A steering and ground speed control mechanism of a vehicle equipped with a dual-path hydrostatic drive system includes a pivot plate fixed to a vertical pivot post at a location between and equidistant from a pair of locations respectively linked to a pair of pump displacement control arms of a pair of pumps respectively coupled for delivering fluid to right- and left-hand drive motors coupled to right-and left-hand ground wheels.  A train of elements for transferring steering inputs from a steering wheel to the pivot plate includes a timed belt and sprocket set with one of the sprockets being fixed to the pivot post and the other mounted to a fixed post together with a quadrant-shaped steering rack for pivotal movement about the fixed post in concert with the rack.  Pivoting the pivot plate in opposite directions from a centered position causes different displacements of the pumps and, hence, in the two drive motors being driven at different speeds.  A train of elements for transferring speed inputs from a speed control lever to shift the pivot plate back and forth in a nearly straight path includes a push-pull cable coupled between the lever and an arm having the pivot post pivotally mounted in one end thereof, with the arm being mounted for pivoting about the fixed post exclusive of the rack and sprocket.  A spring-applied, hydraulically released latch is provided for latching the steering wheel and speed control lever in their respective "centered" and "neutral" positions when hydraulic pressure is absent and a "neutral" start switch is positioned for being activated for completing a vehicle starting circuit only when the steering wheel and speed control lever are in these positions.

Title: Drive circuit for display device
Inventor: ONODERA JUNICHI
IPC: G09G3/296
Filed: 1996-07-15
Granted: 2005-02-08
Abstract: In a display device in which each group of plural drive elements 10 takes charge of the drive of plural picture elements (pixels) and the display luminance changes as the number of sustaining pulses changes that are supplied to PDP16, a constant emission luminance characteristic is maintained by increasing the number of sustaining pulses for larger load when the display load factor is large, and decreasing the number of sustaining pulses for smaller load when the display load factor is small. When displaying multi-tone image by subfield drive method, a display area detect circuit 20 allows to display image always with constant luminance characteristic despite the variation of the display load factor, and to prevent the deterioration of tone characteristic due to the subfield drive method, and further a half tone display circuit 30 allows to decrease the bit number thereby simplifying the configuration of the display area detect circuit 20.

Abstract: A radiator support includes a rigid inner tube member, a rigid outer tube member, and a rubber elastic member. The rigid inner tube member has a radial through concavity formed through the inner peripheral portion in the radial direction, or the rigid outer tube member has a radial through concavity formed through theouter peripheral portion in the radial direction. The rubber-elastic member has a convexity formed at least on one of the inner peripheral portion and the outer peripheral portion. The convexity extends inward or outward, and fits into the radial through concavity of the rigid inner tube member to inwardly project from the inner peripheral portion thereof, or into the radial through concavity of the rigid outer tube member to outwardly project from the outer peripheral portion thereof. Thus, therigid inner tube member can be assembled with an engagement pin of a radiator infavorable engagement, and the rigid outer tube member can be assembled with an engagement hole of a vehicle-side installation member in favorable engagement. As a result, the radiator support can inhibit abnormal noises from generating, and is less likely to come off from the radiator.

Title: Short channel fermi-threshold field effect transistors
Inventor: DENNEN MICHAEL WILLIAM
IPC: H01L29/10
Filed: 1996-07-19
Granted: 2007-10-16
Abstract: A Fermi-threshold field effect transistor includes spaced-apart source and drain regions which extend beyond the Fermi-tub in the depth direction and which may also extend beyond the Fermi-tub in the latera l direction. In order to compensate for the junction with the substrate, the doping density of the substrate region is raised to counterac t the shared charge. Furthermore, the proximity of the source and drain regions leads to a potential leakage due to the drain field which can be compensated for by reducing the maximum tub depth compared to a low capacitance Fermi-FET and a contoured-tub Fermi-FET while still satisfying the Fermi-FET criteria. The tub depth is maintained below a maximum tub depth. Short channel effects may also be reduced by providing source and drain extension regions in the substrate, adjacent the source and drain regions and extending towards t he channel regions. The source and drain extension regions are doped the same conductivity type and doping concentration as the source and drain themselves. A Fermi-FET which is particularly suitable for small linewidths is thereby provided.

IPC: G02B6/38
Filed: 1998-03-27
Granted: 2006-11-28
Abstract: An physical-contact optical fiber connector for optical fibers has improved long-term stability. The fiber surface ends of the optical fibers are coated with a thin, absorption-free film made of very hard material, whereby the resistance to scoring is considerably increased. The thickness of the protective film is such that interfering reflection losses due to differences in the refraction indices are largely avoided. The hardness of the film is greater than that of the optical fiber material. Its optical thickness is also small compared to the operating wavelength. For optical fibers made of quartz glass, a protective film of Al2O3 is used. Other oxides, nitrides, borides, and carbides are also used. For optical fibers made of multicomponent glass or plastic, the protective film is made of an absorption-free material of greater hardness.  The optical thickness of the protective film is between 1/1000 and 1/10 of the operating wavelength. The films are applied using ion-supported processes or ion-beam sputtering or the MicroPlasma process. Due to the small diameter of the rods, a large number can be placed into the coating system and coated at the same time. Thus physical-contact optical fiber connectors are obtained that have virtually unlimited service life and have extremely small insertion losses or connection losses.
