Patent CA-2001073-C (CA)
Inventor: MAZZIOTTI PHILIP J
IPC: F16C33/76

Granted: 1999-12-21
Abstract: An intermediate bearing support for a drive shaft of a vehicle is set forth. An intermediate drive shaft support is required when three or more universal joints are embodied in a drive line between a transmission and a differential.      The new drive shaft support is more compact, uses fewer parts which is brought about in part by the use of symmetrical designs, and is easier to assemble on a drive shaft. Bearing shields or flingers of the support are mounted on the drive shaft adjacent a bearing of the support so that the shields do not have to be specially designed to fit particular drive shafts. For replacement purposes, one replacement kit can be used to rebuild a number of different drive shaft bearing supports.

Patent CA-2026213-C (CA)
Inventor: FIELDER LOUIS D
IPC: G10L19/02
Filed: 1990-01-29
Granted: 1995-04-04
Abstract: A transform encoder/decoder system employs a discrete transform, carefully designed analysis/synthesis window pairs, adaptive transform coefficient quantization, and adaptive bit allocation to encode high-quality music including broadcast and compact disc applications at low bit rates (128 kBits per second). The analysis/synthesis window pairs are carefully designed to achieve sufficient transform frequency selectivity so as to enhance the coder's ability to utilize psychoacoustic masking effects. A synthesis window in the decoder has characteristics such that the product of its response and that of an analysis window in the encoder produces a composite response which sums to unity for two adjacent overlapped sample blocks. Adjacent time-domain signal samples blocks are overlapped and added to cancel the effects of the analysis and synthesis windows. A technique is pro-vided for deriving suitable analysis/synthesis window pairs. In the encoder, discrete transforms analogous to a critically sampled single-sideband analysis/synthesis system generate the frequency-domain transform coefficients. Two transforms used are the Evenly-Stacked Time-Domain Aliasing Cancellation (TDAC) and Oddly-Stacked TDAC transforms. The transform coefficients are nonuniformly quantized by assigning a fixed number of bits and a variable number of bits determined adaptively based on psychoacoustic masking. A technique is described for assigning the fixed bit and adaptive bit allocations. The transmission of side information regarding adaptively allocated bits is not required. Error codes and protected data may be scattered throughout formatted frame outputs from the encoder in order to reduce sensitivity to noise bursts.

Title: Control device for radio communication apparatus
Inventor: NONAMI TAKAYUKI
IPC: H04B7/26
Filed: 1991-03-19
Granted: 1994-03-01
Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed herein is a control device which is suitable for use in a radio communication apparatus employed in a radio communication system using a TDMA method.  A timer circuit for circulating a counted value in a period corresponding to a period of time re-quired to transmit a TDMA frame supplies the counted value to a strobe signal generating circuit.  The strobe signal generating circuit supplies a strobe sig-nal to a radio unit of the radio communication appara-tus when a preset value coincides with the counted value of the timer circuit.  Thus, since the strobe signal is generated without the intervention by a con-trol circuit made up of a CPU or the like, it can be outputted in strict timing.

Granted: 1996-06-18
Abstract: In a key telephone system in which a plurality of data terminals 371 ... 37n such as personal computers are connected to a key service unit 1 connected to a plurality of telephone lines 251 ... 25m, a modem 43 is pooled so as to be usable in common for the plural data terminals 371 ...  37n.   In response to a called party number signal from the Telephone line (e.g. 251), the key service unit 1 selects a single data terminal among the data terminals 371 ... 37n now being in standby status, and closes a communication channel between the selected data terminal  (e.g.  371)  and the modem 43,  so that a status  equivalent  to  that  where  the  selected  data terminal 371 and the modem 43 are directly connected to each  other  can  be  established.    Thereafter,  the  key service unit 1 indicates a called party number signal reception to the modem 43, and the modem 43 transmits a call  to  the  selected  data  terminal  371.    When  the selected data terminal 371 responds to the call from this modem 43, the key service unit 1 closes a communication channel between the modem 43 and the telephone line 251, so that a communication link between the selected data terminal  371  and  the  telephone  line  251  can  be established via the modem 43.   During the process until this communication link can be established,  since  the selected data terminal 371 and the modem 43 are in the status equivalent  to direct  coupling,  the key service unit 1 is not concerned in the communications between the selected  data  terminal  371  and  thus  modem  43,  thus reducing the operational load applied to the key service unit 1.

Granted: 1996-10-15
Abstract: To permit elimination of dampening rollers or an entire dampener in a lithographic, preferably offset printing machine, the printing form is formed as a cylindrical sleeve or jacket (3) fitted over a core (2), in which the cylindrical sleeve or jacket is formed with a plurality of interconnected pores (5), essentially uniformly distributed over the surface (4) and forming, within the sleeve or jacket, a connected pore fluid transfer network. Dampening fluid is then applied to the interior of the sleeve or jacket, for example from a chamber between the cylindrical core (2) and the inner surface of the sleeve or jacket. The outer surface (4) can be imaged with oleophilic substances, for example by a thermal transfer process. To remove the images, for re-use of the printing form without removal from a printing machine, hot gases for example steam can be applied to the interior of the sleeve or jacket, so that the oleophilic substances at the outside will loosen for easy removal, or spall off.
