Title: Drive shaft
IPC: F16D3/06
Filed: 1989-10-30
Abstract: A drive shaft comprises a first joint member (1), a first tubular shaft (2) connected 
on one side with the first joint member, a second joint member (3), a second tu­
bular shaft (4) connected on one side with the second joint member and coupled 
on the other side with the other side of the first tubular shaft so as to transmit 
torque and slide axially, and a coiled spring assembly (20) provided in the 
coupling section of the two tubular shafts for biasing the two tubular shafts each 
other axially oppositely. The coiled spring assembly is composed of a plurality of 
coiled spring units (A,B,C,D) and at least one spacer member (9) which is inter­
posed between the two coiled spring units and has a pair of receiving portions 
with which the ends of the two coiled spring units are fitted so that the two coiled 
spring units are kept out of contact with the inner peripheral surface of one of the 
two tubular shafts forming the coupling section and an outer contact portion held 
in contact with the inner peripheral surface of the one tubular shaft. Since the to­
tal amount of flexure of the coiled spring assembly is limited due to the use of a 
plurality of coiled spring units and the individual coiled spring units are radially 
positioned so as to contact with the inner peripheral surface of the one tubular 
shaft, during rotational motion the coiled spring means is prevented from collid­
ing with the inner peripheral surface of the one tubular shaft and the like, result­
ing in no generation of large noise and vibration during rotational motion.

Title: Binary data signal transmission system
IPC: H04L25/03
Filed: 1990-01-22
Abstract: In a system for transmitting a binary source signal from a data transmitter to a data receiver through a noisy dispersive channel, the data transmitter comprises a sliding block encoder which converts the binary source signal at a given symbol rate 1/T into an encoded binary data signal at a symbol rate P/TN, where P and N are positive integers such that N/P </= <2>log(3)/2 + 0.79248. Since the channel introduces intersymbol interference and noise into the encoded data signal, the data receiver comprises the cascade of a equalizer, a sampler and a reconstruction circuit which serves to reconstruct the binary source signal at the symbol rate 1/T. The improved reconstruction circuit consists of a detector in a cascade with a decoder with a decoder with memory, while the equalizer, sampler and detector are arranged for the detection of a ternary data signal at the symbol rate P/(2NT).

Title: Pump bus to avoid indeterminacy in reading variable bit field
IPC: G06F13/40
Filed: 1990-01-23
Abstract: A data field having a variable number of zero-level 
bits is read by a bus in a digital system, wherein the bus 
is pumped by writing all logical "one" bits onto the bus 
lines just before they are read. The unused bits will 
then be still in a logical "one" state, i.e. a known 
value, rather than floating or at an indeterminate value. 
A program for performing this operation in a computer uses 
steps to prevent other operations such as refresh cycles 
or interrupts from being interposed between the write and 
read cycles. A CPU may use this method to read a system 
identifier value upon boot-up, for example.
