Patent EP-0738926-A2 (EP)
Inventor: TONG HUA-SOU
IPC: H01J9/227
Filed: 1996-04-18
Abstract: The inner surface of a video display panel such as cathode ray tube (CRT) glass faceplate is initially coated with a mixture of one of the primary color phosphors, an organic binder such as polyvinyl alcohol (PVA) diluted with water, and a photoresist agent. The organic binder overcomes the poor adhesion to the glass faceplate of the photoresist which typically includes polyvinyl pyrrolidone (PVP) and reduces the oxygen which decreases phosphor exposure time. To overcome PVA and PVP incompatibilities which give rise to nonuniform film thickness, a vinyl pyrrolidone-vinyl alcohol (VP-VA) copolymer is added to the phosphor, organic binder and photoresist mixture in the range of 0.1-30 wt%. The copolymer with both the VP and VA functioning groups serves as a coupling agent between the PVA and PVP and eliminates incompatibilities between these components. The VP-VA copolymer preferably has a VP/VA mole ratio in the range of 20/80 to 80/20.

Abstract: A method of operating a micromechanical device (12). The device is in a first state. Data for the next state of the device is loaded onto the activation circuitry of the device (18a, 18b) where the next state may be the same state the device is currently in, or a state different from the first state. The equilibrium of the device is shifted away from the next state, by making the data appear complementary to the true data for the next state. When the trapping field is removed or lowered, and a signal to start the transition is provided, the device moves to its new state and the trapping field is reapplied. The data can be made to look complementary by either loading the complements to the true data, or by reversing the polarity of the trapping field.

Abstract: A connector system includes a receptacle that is small and assures precise alignment of mating contacts and terminals. The receptacle includes a circuit board (32) with a laterally-extending row of traces (42), and a receptacle housing (36) with a top wall (44) lying above the traces to form a cavity (16) between them. A plug front portion has a row of contacts (60) for entering the cavity and engaging the traces. The top wall has a row of cam surfaces (120) while the plug contacts have front portions with cam follower locations (112) that slide down along the cam surfaces. This causes trace-engaging locations (114) on the contacts to move down against the traces. The top wall has a row of downwardly-projecting ribs (72) that form the cam surfaces. The plug housing (62) has a row of separators that fit into the spaces between the ribs. The plug has a coax section (230) that includes a pair of laterally-spaced grounded contacts (246, 248), a signal contact (260) with its front portion (262) lying between the grounded contacts, and a grounded tine (264) that lies under the signal contact.

Abstract: An adapter arrangement for electrically testing printed circuit boards consists of two
probe adapters with a uniform grid separation of the probes (9, 9') and two translator
foils (6, 6') on whose sides facing the probe adapters there are contact areas (8) with
the pitch of the probe adapter. On the sides facing the printed circuit board (2) the
arrangement of the contact areas (5) and the contact points (4) located thereon is
the same as the grid on the printed circuit board under test. Between the translator
foils a vacuum is generated with the help of rubber seals (13), a through hole (14),
a valve (15) and a suction hose (16). This vacuum creates a rigid package which
permits good contact with the probes on both sides. The inserted support layers (11),
which can be conventional printed circuit boards, prevent the translator foils from
buckling. The various types of extremely complex printed circuit board can be
electrically tested rapidly and cheaply using this arrangement. The arrangement can
be employed on both double-sided and one-sided electrical test installations.

Abstract: A low cost, high speed multimedia data network is disclosed.
The network preferably includes a fiber optic data bus arranged in a star
topology configuration. Various types of devices or nodes may be placed in
communication with the bus via a specially designed interface. The interface
allows a device to communicate with the high speed network without requiring
that the device have the processing power to receive and transmit data according
to the protocols and demands of the network. The interface may be configured
to match the complexity of its associated device. For intelligent devices, the
interface may allow some of the network-related functions to be performed by
the device itself. For non-intelligent (or "dumb") devices, the interface
performs substantially all of the network-related functions. In general, the
interface provides the capability of insulating a node from the complexities of
the high speed network by receiving data from and providing data to the node
according to the node's data format, and receiving data from and providing data
to the network according to the network's data format. The general messaging
protocols are designed to facilitate the transfer of data in a star topology
configuration, while also facilitating the relatively low cost and flexible
implementation of the network.

Abstract: A frequency cancelling system (40) is disclosed, which
improves reception of a communication signal that is
transmitted at a communication frequency in the presence
of an interference signal which occurs at the same
communication frequency. The frequency cancelling system
(40) generates a reference signal at the communication
frequency, and adjusts the reference signal to be
opposite in phase and equal in amplitude to the
interference signal. The reference signal and the
communication signal are then combined to cancel the
interference signal. Preferably, the reference signal is
generated from the same source (22) as that from which
the interference signal arises. Preferably also, the
interference signal is received during an interval in
which the communication signal is not being transmitted,
and the reference signal is adjusted to be opposite in
phase and equal in amplitude to the interference signal
during that interval.

Abstract: A speech parameter coding method and apparatus

signal with a smaller number of bits than ever. A
dividing section divides a predetermined order number of
spectrum parameters, obtained by division of a speech
signal into frames, for each order number of spectrum
parameters smaller than the divisional order number. A
vector quantizing section searches codebooks for the
divided spectrum parameters for each order number and
outputs a plurality of candidates of codevector in order
of magnitude from the minimum one. An accumulated
distortion calculating section calculates accumulated
distortions for the entire order number for combinations
of codevectors. A minimum Judging section selectively
outputs a combination of codevectors which minimizes the
accumulated distortion thereby to quantize the spectrum
parameter.
