Patent CA-2041795-A1 (CA)
Inventor: GOEWEY JAMES R
IPC: F16F1/387
Filed: 1991-05-03
Abstract: Abstract of the Disclosure A shock absorber mount is described as having two pressed fittings which are mounted in end-to-end relationship.  Each insert has two rigid, radially spaced cylindrical sleeves which are separated by a resilient rub-ber insert.  The inner sleeve of the vertically lowermost fitting, when the fittings are properly mounted on, for example, an automobile frame, extends upwardly beyond the associated outer sleeve and is coated with rubber to enter a hollow bore formed by the inner sleeve of the upper fitting.  The extension allows the lower fitting to initially absorb an upwardly applied axial force until it moves into shock absorbing relation with the upper fitting.  The extension also acts to bolster the radial shock absorbing characteristics of the upper fitting to provide improved shock absorbing characteristics of the mount; namely, low axial shock absorption and high radial shock absorption.
Patent CA-2043459-A1 (CA)
IPC: B60D1/14
Filed: 1991-05-29
Abstract: An improved arrangement for retention of a drawbar is provided in which a single retention member of unitary construction extends laterally within the center sill and fits completely about a longitudinal portion of the butt end of the drawbar.  A vertical connecting pin passes through a vertical opening in the drawbar and is also received in aligned vertical openings in the retention member to connect the drawbar to the retention member.  The longitudinal draft loads of the drawbar are distributed over the entire interfacing portions of the vertical connecting pin and the retention member for transfer to striker members which are integrated with the center sill and ultimately dispose the longitudinal draft loads into the center sill.  The retention arrangement is easily installed and removed and no welding is required between the retention member and the center sill.

Title: Sedimentation centrifuge
Inventor: SUZUKI SOUROKU
IPC: B04B1/20
Filed: 1991-08-14
Abstract: ABSTRACT OF THE DISCLOSURE        A sedimentation centrifuge includes a bowl which is supplied with a feed mixture, i.e., a solid-liquid mixture, from a supply pipe.  When the bowl rotates at high speed, heavy solids are displaced radially outwardly toward and sedimented on the inner wall surface of the bowl.  The solid particles are then discharged through a discharge hole of the bowl and an outlet passage by a screw conveyor in the bowl.  During rotation of the bowl, fins on the screw conveyor assist in separating the liquid into heavy and light liquid phases with increased separation efficiency.  The separated heavy and light liquids are separately discharged from the bowl through respective outlet passages.

Abstract: ABSTRACT    An electrical shunting contact and method for producing the same  for  mounting  between  adjacent  first  contacts in  a  first connector  and  for  self-operatively  providing  a  short  circuit between the adjacent first electrical contacts when corresponding second contacts of a second connector are demated from the first connector.    The   electrical   shunting   contact   comprises   a conductive  member  having  opposing  legs  joined  by  a  resilient bridge, each leg having a non-conductive protuberance projecting outwardly therefrom.  Under demated conditions, a contact edge of each  leg  abuts  the  adjacent  first  contacts  between  which  the shunting contact is mounted to form a short circuit therebetween and  the  non-conductive  protuberance  is  disposed  in  a  chamber located just above the first contact.  The presence of a second contact forces the legs of the shunting contact to be compressed out of engagement with the  first contacts,  thereby creating an open circuit between the adjacent first contacts.

Title: Hot-carrier suppressed sub-micron misfet device
Inventor: SHIN HYUNGSOON
IPC: H01L29/08
Filed: 1990-09-19
Abstract: Hot-carrier suppression in a sub-micron MISFET structure is achieved by providing a drain region which includes a steeply profiled N+ (or P+) doped region (34) in the surface of a semiconductor body (30) with a first epitaxial layer (44) formed thereover having N- (or P-) dopant concentration. A second N+ (or P+) epitaxial layer (48) is formed over the first epitaxial layer and functions as low ohmic contact to the drain region. In a preferred embodiment both the source and drain regions have dopant concentrations provided by N+ (or P+) doped regions (32, 34) in the surface of a substrate (30) with epitaxial layers thereover. The dopant profile reduces the voltage drop across the more highly doped region of the drain and thereby reduces the electric field therein.  Further, the reduction in dopant concentration reduces the electric field due to energy band bending associate with the change in doping level from the N+ (P+) region (46, 48) to the N- (P-) (42, 44) epitaxial layer. The resulting sub-micron device has better long-term reliability. The epitaxial layers are adjacent to and spaced from the gate contact (36) by a dielectric layer (40) such as silicon oxide. In a preferred embodiment (fig. 4C), the dielectric layer (52) is thicker between the second epitaxial layer (46, 48) and the gate contact (36) than between the first epitaxial layer (42, 44) and the gate contact (36).

Title: Digital video signal compression
Inventor: GRAVES ALAN FRANK
IPC: H04N7/12
Filed: 1991-06-05
Abstract: Digital samples of an HDTV video signal are compressed by determining groups each of three successive samples in the video signal lines, the groups in adjacent lines being offset from one another, and transmitting only a first sample in each group (e.g. B in line n). Each of the second (P) and third (Q) samples in each group is compared with magnitudes averaged from three adjacent, transmitted, first samples (A, B or D, C), one in each of the previous, same, and following video signal lines, to determine a closest match. A 2-bit code representing this closest match is transmitted for each of these second and third samples in each group. The groups, and hence the first samples, are offset from one another in adjacent video signal lines, and the sampling frequency is desirably an odd multiple of half the video signal line frequency to offset the sampled pixels in adjacent video signal lines. The invention provides a high compression ratio, which can be further increased by DPCM encoding of the successive first samples.
