Title: A removable record disk apparatus with rotational position control
IPC: G11B27/13
Filed: 1988-09-01
Abstract: In a record disk apparatus which has a motor-driven spindle (31) 
for removably receiving a record disk (30) having an index mark as the 
sole circumferential position indicator, the spindle (31) is provided 
with a tachometer member (31T) with marks angularly displaced a distance 
equal to the disk storing a predetermined number of bytes on the record 
tracks. A byte counter (12) counts byte periods and is reset by each of 
the tachometer marks for indicating offset of the marks from the index 
signal. A register (17) stores the offset as determined by the count in 
the byte counter at index time. A segment counter (20) counts tachometer 
pulses for indicating which of the segments are currently being 
scanned on the record disk. The segment count when coupled with an 
offset indication provides true rotational position to a byte 
granularity. The index pulse resets the tachometer counter to zero. 
The segment counter (20) has a modulus equal to the number of groups of 
bytes (segments) in each of the record tracks.

are required.
Patent EP-0325028-A3 (EP)
Title: Wallcovering substrate formed of textured, continuous multifilament yarns having hydrophilic characteristics
IPC: B32B27/12
Filed: 1988-11-10
Abstract: A textured, continuous, multi-filament polyester yarn has an ethoxylated alkyl aryl alcohol based surfactant incorporated into the interfilamentary structure thereof either during the texturizing process or after the yarn has been made into a gauze-like fabric substrate (30). The ethoxylated alkyl aryl alcohol based surfactant is characterized in that it is water dispersible and water insoluble; has an HLB scale in the range of 7-10; is compatible with conventional wallpaper glues; is of a viscosity in the range of 50-100 SUS depending on the yarn denier; and has a smoke point greater than 350 DEG F. The yarn so treated is formed into a gauze fabric substrate (30) and affixed to the rear surface of a sheet material such as a vinyl wallcovering (40). When the glue (52) is applied to the sheet material the surfactant treatment alters the normally hydrophobic characteristics exhibited by the textured polyester yarn so that the characteristics actually become hydrophilic. Because of the hydrophilic characteristics glue is accepted into and held within the interfilamentary structure of the yarn until the sheet material is affixed to the wall (50) or other surface, thereby bonding the substrate thereto.

Title: Precision operational amplifier
IPC: H03F3/38
Filed: 1988-11-30
Abstract: The precision operational amplifier of the invention 
has at least two stages, a first input differential stage (10, 11) and a 
second high gain stage (20) having its input coupled to the output 
of the first stage. A digital control circuit (40) coupled to the 
output of the second stage is used to supply a correction 
signal to the first stage, the correction signal being 
calculated to compensate for the offset voltage of the first 
stage (10, 11). A digital representation of the correction signal is 
stored so that it may continuously be applied to the first 
stage, whereby the offset voltage of the first stage is sub­
stantially reduced and such reduction can be maintained for 
long periods of times. In a preferred embodiment, the digital 
circuit (40) supplies a second independent correction signal to the 
second stage (20). That signal is also stored so that it may con­
tinuously be applied to the second stage (20), whereby the offset 
voltage of the second stage (20) is substantially reduced and that 
reduction too can be maintained for long periods of time. The 
circuit of the invention may be contained in a single chip, 
monolithic integrated circuit.
