Title: High speed differential sense amplifier for use with single transistor memory cells
IPC: G11C17/00
Filed: 1989-11-20
Abstract: A novel circuit is provided which allows a 
differential sense amplifier to be utilized in 
conjunction with a memory array comprised of a 
plurality of memory cells each containing a single 
transistor. A differential input signal is applied to 
the sense amplifier based upon the binary data stored 
in an addressed memory cell at a rate equal to or 
greater than the differential input signal available in 
prior art differential memory cells having two 
transistors per cell. This is accomplished by 
precharging the selected bit line and a reference bit 
line, and then selecting the word line of the memory 
cell to be read, while causing the reference memory 
cell to conduct. The differential voltage between the 
selected bit line and the reference bit line is then 
sensed to determine the state of the data stored in the 
selected memory cell. The ratio of currents through 
the selected bit line and the reference bit line is 
selected to be other than one, in order to achieve a 
rapid differential voltage swing, and that rapid 
reading of the data stored within the selected memory 
cell.

Title: Focusing error detection circuit
IPC: G02B7/28
Filed: 1989-12-12
Abstract: This invention is concerned with a focusing error detection 
circuit employed in an optical pickup of an optical disk 
apparatus or the like. The laser light received from the re­
cording medium is detected by a photodetector (22) and pro­
cessed in a focusing error computing device (11) to form a 
first focusing error signal (S FE10 ) This first focusing error 
signal (S FE10 ) is sample-held (12) at the timing of periodic 
turn-off of the laser beam and the sample-held signal (S H ) 
is subtracted (13) from the first focusing error signals 
(S FE10 ) to produce a second focusing error signal (S FE11 ). 
This second focusing error signal (S FE11 ) is freed of adverse 
effects caused by temperature changes of the focusing error 
computing device (11) to enable accurate focusing servo con­
trol of the optical pickup device.

Patent EP-0378445-A3 (EP)
IPC: B32B27/18
Filed: 1990-01-15
Abstract: A polymer film laminate is provided having improved machinability on modern high speed belt drive machines, particularly when these machines are set up to form lap back seals. A method of assembling such a film is also provided. The film includes an outside web having an upper surface layer containing a silicone oil. This laminating web can be used with virtually any co-laminate, metallised or not, which is bonded thereto with an adhesive. Upon winding the composite film laminate upon a core, silicone oil is transferred to the inside surface of the laminate, thus providing an inside coefficient friction which is about equal to or less than the outside coefficient of friction. Hot slip properties are also improved upon such transfer. The outside and inside webs are independently formed, which allows the inside web to include coatings or film layers which are not ordinarily usable in a silicone oil-containing film.

Title: Charged particle beam device
Inventor: MUL PETRUS MARIA
IPC: H01J37/18
Filed: 1991-08-06
Abstract: In a charged particle beam device, comprising a charged particle 
source (9) for emitting a charged particle 
beam, a column comprising particle-optical 
elements which are enclosed by a column 
jacket (10) and which serve to accelerate 
and focus the charged particle beam, the 
charged particle source comprising an 
emitter (11) which is accommodated in an 
emitter chamber (19), a vibration-insensitive 
suspension of the emitter is achieved 
by connecting the emitter chamber to the 
column jacket  via  a tubular electrode 
system (25). Because the pumping device (39) 
cooperating with the emitter chamber is 
arranged above the emitter chamber and 
in the prolongation of the column, 
disturbing effects of the pumping device on 
the emitter are reduced. Because the 
power supply unit (47) is arranged in the vicinity 
of the emitter, high-voltage supply leads can be dispensed with, so that 
interference signals cannot reach the 
emitter  via  the supply leads. The use of 
optical communication  via  optical 
fibres (51) prevents the occurrence of undesirable 
potentials in the equipment.
