IPC: G01H9/00
Filed: 1987-11-25
Abstract: There is disclosed herein an acoustic imaging 
system which employs a liquid crystal cell for detecting 
acoustic energy and displaying an image. The cell (40) includes 
a layer of liquid crystal material (42) which is disposed between 
and encapsulated by a pair of cover members (44,46). At least one 
of the cover members is a laminated structure having at 
least two plies (50,52). The plies are of different materials and 
the thickness of each ply is governed by the expression 
n λ/2, where n is an integer, and λ is the wavelength of the 
acoustic energy in the cover materials. This structure 
enhances cell (40) rigidity and the uniformity of thickness of 
the liquid crystal layer (42) in larger sized cells, while 
maintaining good transmission for energy angularly incident 
on the cell.

Title: Method for playing back music pieces recorded on recording media
IPC: G11B27/10
Filed: 1988-09-28
Abstract: A method for performing playbacks of pieces of 
music recorded on recording media, in which a subsequent 
piece of music to be played back is randomly selected 
among pieces of music which do not correspond to any 
playback-inhibition identification numbers nor any 
playback-completion identification numbers both of which 
have been already stored in a memory. The memory 
includes two regions "A" and "B", in which "A" are stored 
the playback-completion identification numbers, and in 
which "b" are stored the playback-inhibition 
identification numbers. Immediately before the 
randomly-selected playback is produced, the 
identification numbers stored in the region "B" are 
transferred to the region "A" so that the subsequent 
piece of music is randomly selected among the pieces of 
music which do not correspond to the identification 
numbers of which are not stored in the region "A", 
whereby the randomly-selected playback can be repeated, 
without necessity of repeated procedure for designating 
any music pieces which are prohibited from being played 
back.

IPC: H02K1/02
Filed: 1988-02-10
Abstract: Certain magnetic alloys are useful for a variety of applications 
including for magneto-optic memory storage media (optical disks). These 
magnetic alloys are difficult to protect against composition alteration through such 
processes as corrosion, oxidation, diffusion, etc. The invention is a multiple-layer 
structure which protects the magnetic alloys against diffusion as well as corrosion 
and oxidation without affecting performance of the magnetic alloy in the optical 
disk. Such magnetic memory storage devices exhibit high bit density and long 
life. They are erasable and inexpensive and highly advantageous for use in high-­
bit memory storage devices.

Title: Parametric path modeling for an optical automatic seam tracker and real time robotic control system
IPC: B23K9/127
Filed: 1988-12-30
Abstract: A control processor in a robotic system treats 
optically sensed locations along the path ahead of the 
tool, which are classified in relation to elapsed distances 
and identified in 3-D coordinates and 3-axes tool orienta­
tion, to apply in real time and under feedforward a control 
signal representing the error between anticipated tool 
position and anticipated sensed location on the path. In 
the process, the anticipated sensed location is obtained by 
reference to a model made ahead of time with the stored 
sensed locations grouped as a function of elapsed distances 
and having a common algebraic feature, such as the slope or 
the change of slope. A taught path for the robot has been 
recovered by the control processor also based on elapsed 
distances and control is related to actual tool position 
provided by the robot.

Title: Liposomal formulations with a high antineoplastic agent/lipid ratio
IPC: A61K31/65
Filed: 1988-03-04
Abstract: A method for encapsulation of antineoplastic agents in liposomes is provided, having preferably a high drug:lipid ratio. Liposomes may be made by a process that loads the drug by an active mechanism using a transmembrane ion gradient, preferably a transmembrane pH gradient. Using this technique, trapping efficiencies approach 100%, and liposomes may be loaded with drug immediately prior to use, eliminating stability problems related to drug retention in the liposomes. Drug:lipid ratios employed are about 3-80 fold higher than for traditional liposome preparations, and the release rate of the drug from the liposomes is reduced. An assay method to determine free antineoplastic agents in a liposome preparation is also disclosed.
Patent EP-0292436-A3 (EP)
IPC: H01F6/06
Filed: 1988-05-13
Abstract: Improved conductors and superconducting magnets are described utilizing superconducting materials exhibiting critical field anisotropy. This anisotropy is one in which the ability of the superconductor to stay in a superconducting state depends on the orientation of a magnetic field applied to the superconductor with respect to the direction of current flow in the superconductor. This anisotropy is utilized in the design of conductors and magnet windings comprising the superconductive material and specifically is directed to magnetic windings (14) in which the direction of high critical current through the superconductor is parallel to the magnetic field (H) produced by current in these windings (14) in order to obtain high critical fields. Particularly favorable examples of a superconducting material are the so-called high - Tc superconductors in which the primary supercurrent flow is confined to two-dimensional Cu-O planes. By arranging the superconductive windings (14) so that the Cu-O planes are substantially parallel to the magnetic field produced by current in these windings (14), the windings (14) will be able to withstand high fields without being driven normal. This maximizes the magnetic field amplitudes that can be produced by the magnet.
