Patent EP-0281191-A3 (EP)
Title: Flat cathode ray display tube
IPC: H01J29/62
Filed: 1988-02-24
Abstract: The display tube includes an electron gun (29) which directs a 
low energy electron beam (30) generally parallel to a flat 
faceplate (14) carrying a phosphor screen (16). The beam is 
deflected in a plane parallel to the faceplate by deflection 
electrodes (38) for line scanning purposes before being reversed in 
direction by a reversing lens (40) and then scanned framewise 
over the input side of an electron multiplier (44) by 
further deflection electrodes (42). The low energy beam in the 
scanning section of the tube is susceptible to the influence of 
ambient magnetic fields. The ensure that the beam correctly enters 
the reversing lens (40) in its acceptance window regardless of such 
fields an electron-optic lens system (50) defining a series of 
alternate high and low voltage regions and constituting in effect 
a series of relay lenses is provided between the gun and the 
reversing lens which periodically re-focusses the beam and 
constrains the beam substantially along a predetermining path with 
respect to the reversing lens.

IPC: H02H9/02
Filed: 1988-02-08
Abstract: A solid state switching circuit is provided with 
a first power sharing circuit (20) which incorporates 
resistive power dissipation elements so that the required 
dissipated power is shared between a main power transistor 
(Q1) and the power sharing circuit. A second power sharing 
circuit (22) is connected in parallel with a portion of the 
first power sharing circuit and operates to provide addi­
tional resistive power dissipation under certain switch 
voltage conditions. The use of this second power sharing 
circuit permits an increase in the required trip time of 
the main switching transistor or improves the reliability 
of the power transistors in the main circuit and the first 
power sharing circuit by lowering transistor stress during 
transient conditions.

Title: A method of managing defective sectors in a disk-shaped information recording medium and an apparatus for performing the same
IPC: G11B20/10
Filed: 1989-07-13
Abstract: A method of and an apparatus for managing 
defective sectors in an information recording medium 
such as a write-once optical disk and rewritable 
optical disk in which many defective sectors may be 
generated and unevenly distributed. In the medium, 
alternative zones are formed which are composed of: a 
prime area for recording user data the capacity of 
which is variable according to the volume capacity and 
partition capacity and the occurrence rate of defective 
sectors; a primary spare area for recording alternative 
sectors; and a primary defect list area for recording a 
primary defect list. Many defective sectors are 
managed in the units of alternative zones. When 
defective sectors cannot be substituted in an 
alternative zone (e.g., when defective sectors are 
locally concentrated), defective sectors are managed 
hierarchically using a secondary alternative area, 
thereby reducing the amount of information to be 
handled for the management of defective sectors. 
Therefore, the size of the apparatus can be reduced, 
and defective sectors can be rapidly searched.

Title: Process for the preparation of bis(aminopropyl)aliphatic glycols
IPC: C07C213/02
Filed: 1989-07-25
Abstract: This invention relates to a process for the separation of acrylonitrile 
used in the cyanoethylation of glycols to produce a bis(cyanoethylated) 
aliphatic glycol from the resulting glycol which is then reduced with hydrogen 
to produce the corresponding bis(aminopropyl) aliphatic glycol. In this 
process, acrylonitrile is reacted with an aliphatic glycol in stoichiometric 
excess and the acrylonitrile removed from the cyanoethylated glycol by 
reaction with aliphatic primary or secondary amine prior to effecting the 
hydrogenation of the cyanoethylated aliphatic glycol in the presence of the 
acrylonitrlle-amine reaction product. The reaction product then can be 
separated by conventional techniques such as distillation.

Title: Data processing system capable of storing firmware data in control memories of an input-output processor with reduced hardware
IPC: G06F9/445
Filed: 1989-08-30
Abstract: In a data processing system having a data path (30) 
between a memory device (11) and input-output devices (12), 
and a holding device (18) for holding first through N-th 
firmware data, where N represents an integer greater than 
one, an input-output processor (13) comprises first through 
N-th control memory layers of control memories (31, 32, 
33) and a data controller (34) connected to the holding 
device. Responsive to a firmware load instruction (23), 
the data controller reads the first through the N-th 
firmware data from the holding device as first through 
N-th read-out data. The holding device makes the memory 
device memorize the first through the N-th read-out data 
as first through N-th memorized data. Connected to the 
control memories, the data controller makes the control 
memories of the first through the N-th control memory 
layers memorize the first through the N-th memorized 
data through the data path. In this event, the data 
controller makes at least one control memory of each of 
the first through the N-th control memory layers 
simultaneously memorize each of the first through the 
N-th memorize data. The holding device may be included in 
one of the input-output devices. The firmware data may be 
stored in the control memories successively from the first 
control memory layer to the N-th control memory layer. 
Alternatively, storage of the firmware data may be made 
from the N-th control memory layer to the first control 
memory layer.

Filed: 1990-05-15
Abstract: A gravure printing plate is formed by a plurality of 
concave portions called cells arranged in vertical and 
lateral directions, four sides of each cell surrounded by 
square walls. One cell group is formed by one core cell 
and four sets of paired cells adjacent to each other

not formed in the wall of the core cell. However, a 
notched portion is formed in either one of two 
intersections of a wall and another wall intersecting 
therewith on the wall separating the paired cells. The 
position of the notched portion is selected to be in point 
symmetry about the core cell. Since the direction of ink 
flow become random in the vertical and lateral directions 
in the cell group due to the notched portions, mottling 
can be prevented.
