Title: Transport apparatus for a single reel tape cartridge
IPC: G11B15/60
Filed: 1989-11-01
Abstract: A tape transport which is sized to fit within an 8 inch 
form factor or footprint, to accommodate prevailing mini/micro 
computer applications, and including operative components which 
are capable of automatically receiving IBM Corporation's 3480-type 
tape cartridge and the web of tape which it contains for 
appropriate introduction to the transport for presentation to a 
high performance magnetic recording head. This permits a use of 
the 3480 tape cartridge in a transport apparatus which is capable 
of fitting within an 8 inch form factor or footprint, and which is 
therefore acceptable for use in connection with many mini/micro 
computer applications, yet which is capable of providing high 
performance (parallel track, high transfer rate) storage and 
retrieval due to its compatability (and interchangeability) with 
the format used by the IBM Corporation in connection with its 3480 
tape cartridge.

Title: Karaoke music reproduction device
IPC: G10H1/36
Filed: 1990-10-31
Abstract: The device generates an audio signal from a sound source using a MIDI signal. The music data consists of many pieces of music stored in a memory device like a database in an on-line host computer or an external magneto-optical disc. The music generation processing operations are carried out by 2 microprocessors, each assigned a different set of functions to speed up the overall processing. The receipt and transfer of data to the sound source from the sequencer is carried out in parallel. The data is subsequently output in parallel and the contents of the buffer are monitored constantly to prevent overflow malfunctions. Clock time is divided to enable the generation of trigger signals to control tempo. By variation of the timing of tee trigger signals in accordance with tempo data taken from the data stream, the tempo can be varied while reducing the reproduction time processing load.

Title: Method for controlling shrinkage in solid state polymeric products
IPC: C08F2/00
Filed: 1990-04-03
Abstract: A method of controlling the shrinkage which occurs in 
the solid state polymeric product, after a polymerizable liquid 
which comprises at least one monomer is polymerized to obtain a 
polymeric solid, comprises carrying out the polymerization in 
presence of a shrinkage-controlling effective amount of a 
preferably finely-divided crystalline solid possessing zeolitic 
sorption properties and which contains available apertures of 
adequate diameter so as to permit at least one species of 
participating monomer molecules to enter the apertures, or which 
had been pre-loaded with at least part of said at least one 
species in the apertures prior to the polymerization. The method 
may be applied to an automatically generated computer-designed 
three-dimensional model, obtained by piecewise assembly and 
polymerization of a polymerizable liquid. The invention further 
relates to a polymeric solid composition obtained by the method 
of the invention, such as e.g. the automatically generated model 
just mentioned, especially when this has been generated within a 
removable solid environment which prevents the transient stresses 
of expansion or shrinkage from causing piece-to-piece distortion. 
The polymerizable liquid including the crystalline solid also 
forms part of the invention.

Title: Systems and methods for providing recovery capabilities
IPC: G06F11/14
Filed: 1991-09-26
Abstract: The present invention is directed to systems and methods for recovering from unplanned failures in object oriented computing environments. The systems and methods of the present invention recover from unplanned failures in an efficient manner by storing recovery information in recovery objects. During recovery operations from an unplanned failure, object instance methods (which were abnormally terminated by the unplanned failure) use the recovery information to identify committable actions which were executed prior to the unplanned failure. The object instance methods then execute committable actions which were not executed prior to the unplanned failure. Thus, according to the present invention, the committable actions which were executed prior to the unplanned failure are not re-executed, and the committable actions which were not executed prior to the planned failure are executed. <IMAGE>

Abstract: A moving picture coding apparatus for compressing
moving picture video signal to a target amount "TARGET" which
has an optimized size to properly fit in a disc. The moving
picture video signal is divided into a plurality of groups of
pictures (GOPs), each GOP has a plurality of frames. During
a first cycle operation, the video signal is compressed by DCT
unit (405) and quantizer (406) using a fixed parameter from
a contant generator (708), and the following amounts are
measured: compressed data amount "GOP(i)" in each GOP;
compressed data amount "Frame(j)" in each frame; and compressed
data amount "GOP_Total" in total GOPs. Using these
measured amounts, appropriate size for each frame is calculated
in a calculator (705). Then, in the second cycle operation,
the video signal for each frame is compressed according
to the calculated appropriate size, and recorded on a disc.

Abstract: A trellis coder, for producing a rotationally invariant code, has a
precoder (14) at the transmission side, and a postcoder at the receiver
side. The combination of precoder and postcoder provides a symbol
sequence which is invariant with respect to rotations through integer
multiples of 90°. The output of the precoder (14) is encoded using a
transparant binary convolutional code (22,24), which may be either
punctured or unpunctured, and mapped onto a two dimensional signal
constellation. The points of the constellation are labelled such that an
anticlockwise rotation through 90° results in a mapping (I,Q) to
( Q ,I), where (I,Q) is at least significant pair of bits of the
label of the original point. The postcoder is implemented without a
feedback loop, which limits error propagation.
