Inventor: NAGATA ATSUSHI
IPC: H04N7/46
Filed: 1990-05-10
Abstract: ABSTRACT OF THE DISCLOSURE        A  moving   image   signal  encoding   apparatus comprises  a  frame  decimating  circuit  for  extracting encoded  frames  from  an  input  moving  image  signal  at specified  intervals,  a  frame  interpolating  circuit  for obtaining  an  interpolated  frame  between  the  encoded frames,  and a circuit for obtaining an error formed by frame  interpolation.    A  moving  image  signal  decoding apparatus comprises a receiving circuit for extracting a frame  code  from  an  inputted  signal,  a  frame  decoding circuit for decoding the frame code to obtain a reproduced frame, and a frame interpolating circuit for obtaining an interpolated  frame  between the  reproduced  frames.  By transmitting an error of the interpolated frame from the encoding   apparatus   to   the   decoding   apparatus   and correcting the error of the interpolated frame with the decoding apparatus, the error of the interpolated frame is eliminated. Alternatively,  depending on the value of the error of the interpolated frame obtained with the encoding apparatus,  circuit determines  the  operation mode as  to whether  the  frame  interpolating  circuit  of the decoder carries out frame interpolation or preceding value holding and  sends  a  flag  to  show  the  operation  mode  to  the decoder,  so that improvement is given when the error of the interpolated frame is large.
Patent CA-2016630-A1 (CA)
IPC: H04L27/34
Filed: 1990-05-11
Abstract: In a transmitter, a modulator switchably operates on one of two modes of operations, that is, in a first mode of the operation, such as an offset QPSK, FSK or .pi./4 shift QPSK, the amplitude of an output signal of the modulator does not become zero at any instant, and in a second mode of the operation, such as two-phase FSK or four-phase PSK, the output signal of the modulator is 100% amplitude-modulated or 180 phase-modulated.  The operation mode is switched by changing the mode of the parallel input signals to the modulator, where the parallel signals have been converted from a serial input data signal to be transmitted.          After the first mode operation is switched to the second mode operation the output signal is interrupted preferably on a first moment that the amplitude of the output signal becomes zero, as well as, before the second mode operation is switched to the first mode operation the output signal is resumed preferably on a second moment that the amplitude of the output signal is to become zero.          The interruption of the modulated output signal may be done by cutting the local frequency or modulated signal, or by the parallel input signals.  Thus, a spurious wave is not generated on the transition of interrupting or resuming the modulated transmittal wave.

Abstract: ABSTRACT OF THE DISCLOSURE    The  improved annular seal  of the present  invention provides  a  seal  across  an annular  space between  facing cylindrical surfaces and includes an outer annular ring, inner annular ring, the gap between the outer annular ring and the inner annular ring being suitably sealed at one end thereof so that the open end is open to admit pressure which is to be sealed between the two rings,  an outer sealing element on the exterior of said outer annular ring, and an inner sealing element on the interior of said inner annular ring so that pressure exerted between the annular rings urges them apart and their sealing elements against the surfaces of the annular space. In another form of the invention three annular rings are provided with one end of the inner and outer rings being sealing to the end of the intermediate ring and with sealing elements on the exterior of the outer ring and on the interior of the inner ring so that the sealing elements are urged into sealing engagement with the surfaces of the annular space.  Another form of the invention includes annular rings which vary in thickness from one end to the other so that they may have greater or less flexibility as needed to provide a response to the pressure responsive movements of the inner and outer members.

Title: Brake spider assembly
Inventor: CHO SUNG J
IPC: B60T1/06
Filed: 1990-11-20
Abstract: ABSTRACT A brake spider for a braking system on over the road trailers.  The brake spider is to be welded to a tubular axle of the vehicle and is of composite construction.  An inner annular member is formed from a pair of rolled, semi-circular steel plates which are joined end to end to form a circular hub.  An outer member is cast from ductile cast iron.  The inner member includes apertures disposed about the circumference and extend through the hub such that the cast iron fills the apertures and mechanically interlocks the two members together as a composite of cast iron and steel.  Because the inner hub portion is steel, it can readily be welded to the vehicle axle.  A method of casting the spider of this construction is disclosed including an alternative which uses hollow tubular steel, pierced to form apertures, and sliced to provide the circular inner member.  The circular member is used to core the casting mold into which molten ductile cast iron is cast against the inner member and into the apertures to interlock the members as a composite.
