Patent EP-0418602-A3 (EP)
Title: Anti-lock device
IPC: B60T8/40
Filed: 1990-08-28
Abstract: A vehicle brake system having an anti-skid system with, at least one anti-skid valve assembly disposed in a brake line that leads from the master brake cylinder to the wheel brake. To pump pressure fluid out of the wheel brake to the master brake cylinder, a return feed line is provided. Located in the return feed line, in succession in the pumping direction following a pressure fluid reservoir, are a throttle and a return feed pump driven by an electric motor. In order to keep the feedback at the brake pedal slight during an anti-skid control event involving small quantities of pressure fluid to be returned, yet to make sufficiently large quantities of pressure fluid available in the master brake cylinder upon major brake pressure reduction, the following provisions are made: The pumping flow of the return pump can be increased with increasing pressure in the pressure fluid reservoir and/or upon attainment of a predetermined fill level in the pressure fluid reservoir and/or with an increasing volumetric flow of pressure fluid to be pumped back out of the wheel brake.
Patent EP-0429971-A3 (EP)
Title: Method and apparatus to produce subliminal sound recording
IPC: G11B20/00
Filed: 1990-11-15
Abstract: Subliminal sound recordings are produced, in which, in addition to the use of a primary carrier such as music, two sound channels are used to supply subliminal messages to the brain. On one channel which stimulates the left cerebral hemisphere, the supplied message comprises meaningfully spoken, forward-masked, enabling affirmations delivered in canonical fashion by a male voice, a female voice and a child's voice. On the other channel, which stimulates the right cerebral hemisphere, instruction messages are recorded with backward masking (or in metacontrast) using the same voices. The three voices are recorded in canonical fashion with full echo/reverberation effect. The sound tracks are mixed using a special processor which converts sound frequencies into electric pulses and controls the synchronisation of the subliminal message in stereo with the primary carrier. The processor maintains a constant level differential between the primary carrier and the speech of the subliminal message and ensures, especially since the subliminal message is recorded in canonical fashion with full echo/reverberation effect, that nothing is lost from the message. The primary carrier should consist of continuous music without pauses and without significant differences in movement.

Patent EP-0413607-A3 (EP)
IPC: G06F3/0354
Filed: 1990-08-17
Abstract: A pen-type computer input device is used to move a 
cursor on the display of a computer system or enter data 
such as of figures, letters, numerals, or the like into a 
computer system. The pen-type computer input device 
includes a shank, a ball rotatably supported on the tip end 
of the shank, a pair of rotatable members rotatable about X 
and Y axes extending perpendicularly to each other and held 
in rolling contact with the ball, and a rotation detector 
for detecting the direction in which the rotatable members 
rotate and the distance by which the rotatable members move. 
Since the rotation of the ball is directly transmitted to 
the rotatable members and the distance by which the 
rotatable members move is detected, the pen-type computer 
input device is small in size and can easily be handled.

Title: Method of reproduction from magneto-optical recording medium
IPC: G11B11/105
Filed: 1991-12-23
Abstract: The present invention is intended to improve the track recording density and track density of a magnetooptic recording medium (1) to prevent the deterioration of characteristics due to the variation of reproducing power. After recording information signals on a magnetooptic recording medium having at least a reproducing layer (3), an intermediate layer (4) and a record hold layer (5), the direction of magnetization of the reproducing layer is turned in the direction of an initializing magnetic field. The reproducing layer (3) is irradiated with a laser beam and a reproducing magnetic field is applied to the same simultaneously to heat the reproducing layer (3) in a temperature distribution so that a region remaining in an initialized state, a region to which information signals are transferred and a region magnetized in the direction of the reproducing magnetic field are formed. Magnetic signals are read from the region of the reproducing layer to which information signals have been transferred. <IMAGE>

Title: Treatment of copper sulfide concentrates
IPC: C25C1/12
Filed: 1992-07-17
Abstract: A hydrometallurgical method comprising a leaching operation is provided for recovering copper from particulate copper sulfide flotation concentrate containing at least about 20% copper by weight, a significant portion of the copper in the copper sulfide concentrate being in the cuprous state. The copper sulfide flotation concentrate in the finely divided state is subjected to leaching with an alkaline solution of ammonia plus ammonium sulfate of concentration ranging from about 30 gpl to 150 gpl of ammonia and about 25 gpl to 200 gpl of ammonium sulfate at a temperature ranging from about 10 DEG C to 95 DEG C, preferably about 20 DEG C to 40 DEG C, the amount of sulfide concentrate in the leaching solution ranging from about 25 gpl to 500 gpl proportioned at least stoichiometrically to the ammonia concentration of the leaching solution. The sulfide concentrate is leached under substantially ambient pressure while continuously aerating the solution for a time at least sufficient to dissolve the cuprous copper and oxidize it to the cupric state while avoid or substantially minimizing the oxidation of sulfide sulfur to sulfate, and thereby obtain a filtrate containing at least about 15% of the total amount of copper in the concentrate and provide a washed residue containing at least about 20% copper by weight comprised substantially of cupric sulfide. The copper in the leaching solution after further processing is subsequently recovered by electrowinning. The residue can be further treated in a smelter to recover copper therefrom or upgraded by subjecting the residue to conventional flotation and provide a secondary flotation concentrate containing at least about 30% by weight of copper. <IMAGE>

IPC: G03F7/075
Filed: 1996-08-02
Abstract: To the surface of a semiconductor substrate made of
silicon, isopropenoxytrimethylsilane is supplied as a surface
treating agent to render the surface of the semiconductor
substrate hydrophobic and increase adhesion to the
semiconductor substrate. Thus, Si(CH 3 ) 3  (trimethylsilyl group)
is substituted for the hydrogen atom of an OH group on the
surface of the semiconductor substrate, resulting in (CH 3 ) 2 CO
(acetone). Subsequently, a chemically amplified resist is
applied to the surface of the semiconductor substrate and
exposed to light by using a desired mask, followed sequentially
by PEB and development for forming a pattern. Since the
surface treating agent does not generate ammonia, there can be
formed a pattern in excellent configuration with no insoluble
skin layer formed thereon.

Abstract: An indium gasket (80) having a configuration which
allows the indium to reach its yield point at a relatively
low contact pressure. The indium gasket is provided
with a multiplicity of openings (84) which are
filled by the deforming indium during compression
between the cryocooler and the cryocooler interface
sleeve of a superconducting magnet system. The
creation of openings in the gasket has the effect of
decreasing the mechanical interface pressure at which
the indium yields. The indium flows at a mechanical
interface pressure that does not exceed the structural
strength requirements of the cryocooler. The indium
flows into the empty spaces formed by the openings (84),
thereby providing the necessary thermal conductance
between the cryocooler and the interface sleeve. The
result is a relatively small temperature difference
between the interface sleeve and the cryocooler during
cooling of the superconducting magnets.

selected groups are toggled with RAS. If a group contains a
known defective word line, that group is either not addressed
or its selection is disabled. In each selected group, one
row, alternating rows or, all of the rows may be selected.
