Title: Digital radio transmission system for a cellular network using the spread spectrum technique
IPC: H04B7/26
Filed: 1989-09-20
Abstract: In each cell, a base station (BS) and mobile user stations (MS) each having a transmitter (S), a receiver (E) for multi-path reception and a control unit (ST) are present. Each cell is associated with exactly one set of several sequence sets of the auxiliary function used for the band spreading. Sequences from various sets have the characteristic, pair-by-pair, that the absolute values of the normalised periodic cross-correlation functions are much smaller than one and in a case of sequences within a set, the cross-correlation function is optimally small around the zero point pair-by-pair. In the base station (BS) the transmitted signals are data-synchronously processed for all simultaneous connections and the data clock of the received signal is used as data clock of the transmitted signal of the user station (MS).

Title: Inserted blade hob
IPC: B23F21/16
Filed: 1989-10-06
Abstract: The invention relates to an inserted blade hob for producing gear- tooth systems by the hobbing method. Here, its rows (3) of cutting teeth are on the one hand to be fastened precisely and firmly in place so that the high and varying cutting forces can be absorbed at high accuracy, and on the other hand, for recoating - TiN coating - after the tooth face has been sharpened, the rows (3) of cutting teeth are to be capable of being readily disassembled and then reassembled again precisely. This is made possible due to the fact that, for fixing the rows (3) of cutting teeth, the socket head cap screws (7), during tightening, bear on the one side with a sector of the bottom margin (8) of their screw head (9) on the pocket bottom (10) in the base area (11) of a back of a row of cutting teeth and on the other side with their head periphery along a generating line (12) of the front side (13) of the adjacent base (14) of the row of cutting teeth. <IMAGE>

Abstract: A diffractive bifocal eye lens, an optical system, and processes for 
fabrication of such lenses are disclosed. The optical system includes the 
following principal elements in optical alignment along an optical axis 
(10), for accomplishing the indicated steps of the process: a laser (12) 
for emission of ultraviolet light along the optical axis (10); a zone 
plate mask (18) in the path of irradiation by the laser; and an imaging 
lens (20) to project, with radiation from the laser (12), an image of 
the mask on the concave inner surface (30) of an eye lens mounted 
coincident with the image surface of the optical system, thereby 
ablating the eye lens imagewise of the mask to generate a phase zone 
plate on the eye lens. The laser beam scans the zone plate mask (18) 
to generate a composite image on the image surface. Alternatively, 
the phase zone plate (18) is generated on the concave surface of a 
glass blank at the image surface to form a tool from which molds, and 
in turn lenses, are replicated. The light source is an argon fluoride 
excimer laser (12), emitting at 193 nm. The lens is a variable 
magnification lens to project various size images of the mask for 
producing zone plates of various powers as desired.

Title: Capillary separation system with electric field assisted postseparation mixing
IPC: G01N27/447
Filed: 1989-11-01
Abstract: A capillary zone electrophoresis (CZE) system provides for rapid, 
non-turbulent post-separation diffusional mixing of sample eflluent with a 
fluorogenic-labelling reagent permitting sensitive detection of well-defined 
sample component zones. A separation capillary extends into a mixing 
capillary so as to define an annular gap therebetween. The eflluent of the 
separation capillary is mixed with the labelling reagent, which is 
introduced through the annular gap. A power supply and opposing 
electrodes establish an electric field which induces electro-osmotic flow of 
the sample and charge-related differential electrophoretic migration to 
define component zones. The electric field also causes the separation 
capillary effluent to diverge as it issues into the mixing capillary so as to 
facilitate diffusional mixing with the reagent fluid flow without causing 
significant turbulence. Thus, fluorescence labelling is effective with 
minimum zone broadening. This system combines the high resolving 
power of CZE separation with the sensitivity of labelled fluorescence 
detection to attain an improved system for analyzing biological samples.

Title: Process for the production of polyurethane foam
IPC: C08J9/14
Filed: 1989-12-15
Abstract: A polyurethane foam is produced using acetone as an auxiliary blowing agent. A polyol, an isocyanate, water, acetone and a catalyst for catalyzing the formation of polyurethane are mixed to produce an unfoamed liquid mixture, which is then retained in bulk form, preferably in an open-topped reaction vessel, for a dwell time during which an exothermic reaction occurs and the liquid foams. Finally, the foaming liquid is spread on to a surface on which it is allowed to expand and form a solid polyurethane foam material. Significant reductions in the amount of auxiliary blowing agent can be achieved, as compared with conventional formulations using methylene or CFC's as auxiliary blowing agents.
Patent EP-0359670-A3 (EP)
Title: Optical pickup apparatus
IPC: G11B7/09
Filed: 1989-09-14
Abstract: Light is condensed on a recording medium (20) by an objective 
lens (11), and light reflected from the recording medium passes 
through the objective lens and is split into light along two 
optical paths (P,5) via a condenser lens (5) and beam splitter (6). 
A light-receiving surface (7) having an area smaller than that of 
the irradiation pattern of the returned light when the objective is 
focused is disposed on the inner side of a focal point on one 
optical path, and an identical light-receiving surface (8) is 
disposed on the outer side of a focal point on the other optical 
path. The arrangement is such that the photoelectric outputs of the 
two light-receiving surfaces (7,8) coincide when the objective lens 
(11) is focused. Preferably, the light-receiving surface is divided 
into four portions by a straight line, which is obtained by 
projecting the track direction of the recording medium, and a 
region having line symmetry with respect to the straight line and 
an area smaller than that of the irradiation pattern when the 
objective is focused. A tracking error signal of the objective lens 
(11) is obtained by correcting a difference signal between 
light-receiving surfaces on the inner side by a low-frequency 
component of a difference signal between light-receiving surfaces 
on the outer side.

Patent EP-0458381-A3 (EP)
IPC: H01L29/06
Filed: 1991-05-08
Abstract: A semiconductor device with a MOS transistor particularly having a 
closed layout plan in which the drain region (20) is laterally surrounded 
by the source region (14) and the channel region (18) and having an 
extended charge carrier drift region (21) between the channel (18) and 
drain (20) regions, thereby achieving high reverse breakdown voltage. 
An oxide or other dielectric layer (22) is provided on the surface 
of the drift region (21), and on said layer (22) between the gate (24) 
and drain (28) electrodes a crossover path is formed by a succession of 
unconnected narrow conductive strips (34,35...) extending transversely to 
such path and having a dielectric coating thereon. A high voltage 
external connection bus (36) for the drain electrode (28) traverses such 
crossover path and extends through a gap formed by a disjuncture 
in the gate (24) and source (26) electrodes. Since the length of each 
of the conductive strips (34,35...) greatly exceeds the width of the 
connection bus (36), the coupling capacitance between each 
strip (34,35...) and said bus (36) is much less than the coupling 
capacitance between each strip (34,35...) and the underlying 
portion of the drift region (21). The drift region (21) can thereby 
be effectively shielded from the electric field of the connection 
bus (36) by including a sufficient number of conductive strips (34,35...) 
in the crossover path traversed by the connection bus (36).

Patent EP-0574038-A3 (EP)
IPC: A61K9/12
Filed: 1989-09-26
Abstract: An apparatus for use in inhaling pharmaceutical 
aerosols. The apparatus includes a mouthpiece (10) and a 
rigid housing (30) for receiving an aerosolized medicine. 
The rigid housing has one or more orifices (60a-60b) which are 
spaced from the mouth piece so that flow through the 
housing is possible but is limited by the orifice(s) 
to a desired volumetric flow rate. The patient is 
aided by having the initial velocity of the 
aerosolized medicine reduced to zero by virtue of 
the initial delivery of the same to the housing 
interior, and by having the volumetric flow rate of 
the inhaled medication maintained below required 
limits thereby providing the conditions for optimal 
dosing. Further, the ability of the patient to 
inhale to total lung capacity with the flow through 
chamber enhances penetration of aerosolized drug to 
the lung periphery, and improves the ease of use for 
the patient.

Title: Dry cleaning of semiconductor processing chambers.
Inventor: YE YAN
IPC: H01L21/302
Filed: 1994-06-10
Abstract: In accordance with the disclosure, the plasma dry cleaning rate of the walls of semiconductor process chamber (102) can be improved by placing a non-gaseous dry cleaning enhancement material in the position which was occupied by the workpiece (104) during semiconductor processing. The non-gaseous dry cleaning enhancement materials is either capable of generating dry cleaning reactive species and/or of reducing the consumption of the dry cleaning reactive species generated from the plasma gas feed (108) to the process chamber. When process chamber non-volatile contaminant deposits are removed from plasma process chamber surfaces during plasma dry cleaning by placing a non-gaseous source of reactive-species-generating material within the plasma process chamber, the non-gaseous source of reactive-species-generating material need not be located upon or adjacent the workpiece support plateform: however, this location provides excellent cleaning results in typical process chamber designs. <IMAGE>
