Title: Single revolution disk sector formatter
IPC: G06F3/06
Filed: 1985-05-22
Abstract: A track of a disk device is formatted on a single revolution 
of the disk by using a read only memory (ROM) to store 
control codes and a random access memory (RAM) to store 
address field and data field bytes. A DMA controller simul­

into a control first in-first out memory and data codes are 
read into a data first in-first out memory. The control codes 
are applied to a decoder whose output signals control cyclic 
redundancy check and error detection and correction logic 
as well as the data first in-first out memory. The serial output 
from both the data first in-first out memory and the cyclic 
redundancy check logic are written on disk track.

IPC: G09G3/30
Filed: 1985-12-20
Abstract: A driver circuit for an electroluminescent matrix-type 
display includes a brightness control circuit (430) for essen­
tially eliminating variations in luminescence (inverse sha­
dowing) of display pixels (101) by controlling the time rate of 
change of the pixel drive voltage at and above the threshold 
voltage for light emission. The brightness control circuit 
(430) varies the row drive voltage (Rhv) to compensate for 
load variation arising from changes in the number of pixels 
to be lit in a row. It includes a counter (435) for counting the 
number of pixels to be lit, a conversion circuit (440) for 
converting the count into an analog voltage (443) and a 
summation circuit (445) for adding the analog voltage (443) 
to a minimum row drive voltage (Rhv(min)). The brightness 
circuit (430) is reset for each new row to be driven to develop 
a new count of pixels to be lit from pixel selection pulses to a 
column driver circuit (420).

Title: Encoding method for time encoded data
IPC: H03M7/42
Filed: 1985-06-26
Abstract: A method of encoding time encoded data in which a stream of time encoded symbols representing the data is divided into a number of successive time frames. The repetition frequency of each symbol in each time frame is determined and a precursor code, indicative of the symbols according to their repetition frequency, is derived for each time frame. A linear or non linear code, or any combination thereof, is assigned to the symbols in accordance with the precursor codes to produce a code series for each time frame. The precursor codes and code series for the time frames are then combined thereby to achieve a reduction in the bit rate of the digital data stream representing the data. The combined precursor codes and code series may be stored before or after transmission.

Abstract: A superconductor constructed through the steps of em­
bedding a plurality of Nb wires (22) into a Cu-Sn alloy region 
(26), inserting the mass into a vanadium cylindrical wall (28), 
placing said latter mass into a copper pipe (32), and applying 
heat treatment to produce a Nb₃Sn compound superconduc­
tor (24) around the Nb wire (22). A V₃Sn compound is formed 
inside the vanadium barrier wall (28) of the said superconduc­
tor. Since, however, the V₃Sn compound (30) does not indi­
cate superconductivity at the liquefied helium temperature, 
A.C. loss is reduced to a negligible extent, even when im­
pressed with pulse current or A.C. current.

IPC: G03G15/23
Filed: 1986-06-24
Abstract: A document printer includes sheet-feeding apparatus 
(20) for sequentially presenting both faces of a print-receiving 
sheet to a print station. According to a preferred embodiment, 
such apparatus features, as part of the duplex sheet path, 
reversible sheet-feeding (32) means operable in first or se­
cond active modes for selectively feeding sheets into and out 
of a chute (34), located upstream from the feeding means, to 
reverse the sheet's lead edge/trail edge orientation. Such 
sheet-feeding means is also operable in a passive mode in 
which it allows sheets to advance, without substantial interfe­
rence, downstream therepast to a registration position. Con­
trol means (LCU) are provided for switching the feeditig me­
ans from one of its active modes to its passive mode after a 
sheet has been advanced into the reversing chute to the ex­
tent that the sheet buckles, whereupon the restoring force in 
the sheet propels the leading edge of the sheet past the feed 
means (32) and into engagement with a registration gate (30) 
located at the registration position.
