Patent EP-0347102-A3 (EP)
Title: Magnetic disk file recording with variable track width and variable track density
IPC: G11B5/60
Filed: 1989-06-08
Abstract: A magnetic recording apparatus and method for the constant 
frequency recording of concentric data tracks on a magnetic recording 
disk in a manner to provide continuously reducing track width and 
continuously reducing track-to-track spacing from the disk's inner 
track to the disk's outer track. A magnetic recording head moves on a 
path from the disk's inner track to the disk's outer track. The head's 
gap-to-radius skew increases as the head moves from the inner track to 
the outer track. Thus, the gap's width-projection onto a disk radius 
at the location of each track continuously decreases in length, from 
the inner track to the outer track. As the track width progressively 
decreases, the track-to-track spacing also decreases, to thereby 
provide higher track density at the disk's outer tracks. A flying head 
having a parallelogram shaped slider is described, allowing use of the 
invention in non-contact recording.

A system of operation and a mixing chamber (100) useful in connection with dosages from the pump (10) are interconnected with the pump.
Patent EP-0367466-A3 (EP)
Title: Deposition processes
IPC: G02F1/1335
Filed: 1989-10-23
Abstract: In a process for depositing a planarising material in spaces 
(5,6) between a pattern of regions (1,2,3), such as dye stripes or 
dots, on a substrate (4), the planarising material is deposited as a 
layer (7) over the pattern. The substrate is irradiated, from the 
reverse side, by a source (8) of radiation, such as UV, to which the 
pattern material is opaque and to which the planarising material is 
responsive such that it is rendered insoluble to a particular solvent. 
The radiation acts on only those parts (9-12) of the planarising 
material which are in the spaces. The remainder (13-15) of the 
planarising layer is then removed by use of the solvent. 
Alternatively, or additionally, an ITO or other UV transparent layer 
may be formed over the pattern and a layer of resist formed thereover. 
The radiation then passes through the spaces and acts on only the 
resist areas over the spaces to render them soluble. Those areas and 
the ITO layer beneath them are then removed by etching, leaving ITO 
areas accurately aligned with the pattern. The process may be used 
in the manufacture of LC displays or semiconductor devices.

Title: Diode laser
IPC: H01S5/227
Filed: 1990-02-23
Abstract: A buried heterostructure tunable diode laser (100) 
or laser array and a method for making the same are 
disclosed. The active region layer (108) is buried 
between two lead salt semiconductor layers (106,110)

Inventor: CHUNG JERRY YEEMING
IPC: H04N1/405
Filed: 1996-06-14
Abstract: Compensation for pixel aberrations (83,85) in a laser printer is
accomplished by altering pixels in accordance with pixel location. A projection
of a scan line is skewed (83',85') with respect to a line normal to the surface of
an optical photoreceptor (OPR 79), which results in a change in the shape of
projected pixels (83',85'). Selected pixels (83') are augmented in order to
adjust their shape. The additional optical energy may be applied at the sub-pixel
level so that a threshold of energy depletion on an optical photoreceptor (OPR) is
not reached where image development would occur. Alternatively, the
additional energy may be applied in a manner which provides additional
development to simulate a pixel having a desired width across a scan line. The
invention allows a scan line to be produced in which pixels across the scan line
are made more uniform.

Inventor: OLANDERS PETER
IPC: H04B7/26
Filed: 1996-09-20
Abstract: The invention relates to a method at a digital radio
communication system such as DECT which makes possible to increase
said system with further frequency bands with retaining of the
dynamic channel allocation and with possibility to at the same time,
within the same time frame, be able to use both the frequency bands.
This is attended to by that a time slot in DECT's time slot structure
is given a special function which results in that, when a base unit
at channel scanning reaches said time slot, a scanning etc starts
within the ISM-band and if the dynamic channel allocation algorithm
(DCA) chooses to use the time slot, then base station and portable
will switch themselves for transmission on the ISM-band. Further
there is a time slot on the ISM-band which in corresponding way
functions as communication link towards the 1800 MHz-band, at which
if the dynamic channel allocation algorithm chooses to utilize this
time slot, base station and portable switch themselves for
transmission on the 1800 MHz-band.
