Patent EP-0811766-A3 (EP)
Inventor: YANAGISAWA KIYOSHI
IPC: F04C29/00
Filed: 1997-05-30
Abstract: A displacement type dry vacuum pump having dual shafts is
disclosed. According to the present invention, the process gas
is exhausted from a processing chamber through three compartments,
a gas admittance pump section, a central drive motor section, and
a gas discharge pump section to resolve the performance problems
encountered in conventional dual shaft displacement type vacuum
pumps. By placing the drive motor section in the center, thus
separating the gas exhaust at low pressure from the processing
chamber to an atmospheric pressure, to carry out the exhausting
process in two stages, a number of advantages are obtained. Each
rotor can be made to suit the pressure requirements so that the
low pressure side rotors are made to displace a higher volume of
gas than the rotors in the higher pressure exhaust section. By
placing the drive motor in the center of the pump, it becomes
possible to design a pump having the dual shafts supported only
at one end, thus enabling to mount the rotors at the free ends
of the pump which are closed with end plates which can be removed
easily for servicing the pump sections. Also, the bearings are
less exposed to harsh environments, and the exhaust gas can be
flowed through a pipe provided in the stator section of the drive
motor, so as to enable control of the temperature of the exhaust
gas. Synchronous operation of the dual shaft pump by the magnetic
coupling enables to lower power consumption and to extend the range
of operable pressures.

Abstract: A process for developing fine pitch vias (18) in a dielectric material (14),
such as thick-film and tape dielectrics, and dielectric materials formed
thereby. Via formation is particularly amenable to diffusion patterning
techniques, in which an imaging material is deposited in the form of
complementary interdigitized shapes that maximize image material volume in
order to form vias that extend completely through the dielectric material,
while also assuring sufficient via spacing to prevent merging of adjacent vias
during imaging. A preferred shape for the resulting diffusion-imaged vias,
and therefore the deposited imaging material, is triangular, with the
orientation of adjacent triangles being such that spacing between the deposited
imaging material is comparable to the spacing between conductor traces (12)
associated with the resulting vias.

Abstract: A memory controller (12) is equipped with a memory data search circuit (35) for carrying out an
identifying operation of management information corresponding to a segment located in front of or behind a
segment serving as a reference for an editing operation on a recording medium (1) through search and
comparison processing of managing information (U-TOC). A system controller (11) does not receive search
data and execute the data search but only sets the comparison standard and an initial value and outputs an
execution control signal. The editing operation performed reduces wasted space on the recording medium
(1), such as a disc, and eliminates "trash areas" which are not addressable in the U-TOC.

Abstract: A DVD player that integrates a DVD device into a personal computer is
provided. As such, the personal computer is able to output audio-visual works from a DVD
CD-ROM. When integrating a DVD device with a personal computer, various problems
must be overcome. For example, in a personal computer, the video display is controlled by a
graphics controller, and in order to render an audio-visual stream in a personal computer, the
audio-visual stream and the graphics controller must be synchronized. The synchronization
problem arises because the graphics controller only displays data at the beginning of
33.4 millisecond time intervals. Thus, although the audio portion may be played almost
immediately, the video portion may have to wait for up to 33.4 milliseconds before being
displayed. In this manner, the audio portion and the video portion become unsynchronized
which means that the audio portion plays before the corresponding video portion is displayed.
The DVD player solves this problem by synchronizing the start of the audio-visual stream
with the graphics controller so that the time at which a video sequence is displayed coincides
with one of the graphics controller's 33.4 millisecond time intervals.

Abstract: A method and apparatus for exploiting the power of existing device
independent graphics and text manipulations, while providing a high level
of client-side performance for interactive applications using an object
oriented client-side library of constructs. The client-side constructs are
analogous to the constructs of a selected server-side imaging model, so that
the power and performance of existing imaging models (for example,
constructs of the PostScript language) are exploited. In an exemplary
embodiment, the client-side constructs are provided for use with the C++
programming language. By establishing a client-side object model using a
library of constructs analogous to server-side imaging model constructs,
program execution speed and efficiency can be improved without sacrificing
the device independence of the imaging model. Using a common base
class (i.e., a base class common to all output device platforms), an inherent
level of transparency between printing to a display and printing to a file or
to a printer is achieved in the client-side application development. Thus,
the coupling of a complete representation of a given imaging model with
the advantages of an object model written in a high level compiled
language, such as the strongly-typed C++ language, enables true what-you-see-is-what-you-get
(WYSIWYG) applications to be efficiently developed and
implemented.
