Abstract: Disclosed is a method of accurately, simply forming a light absorbing layer for improving contrast in a transmission screen including micro glass beads two-dimensionally arranged. A light absorbing layer made from toner is formed on glass beads held in a transparent adhesive layer up to a thickness sufficient to cover the glass beads. The light absorbing layer is irradiated with parallel rays of light in the direction from a transparent substrate, to melt and remove only a portion of the light absorbing layer positioned over a light outgoing portion of each glass bead by the energy of the rays of light converged through the glass bead. By suitably selecting a material of the light absorbing layer, openings can be formed in the light absorbing layer by means of combustion, sublimation or ablation due to the energy of the converged rays of light.

Abstract: An open drain I/O driver includes an input node, an output node, a first reference node, a first transistor, and noise immunity circuitry. The first transistor has its gate coupled to the input node and its conducting path coupled in series with the output node and the first reference node. The first transistor operates to uncouple the output node from the first reference node in response to an input voltage applied to the input node. The noise immunity circuitry keeps the output node uncoupled from the first reference node during undershoot noise in a first reference voltage that causes the first transistor to change from an off state to an on state. The noise immunity circuitry includes second and third transistors. The second transistor has its gate coupled to the input node and its conducting path coupled in series with the conducting path of the first transistor. The third transistor is configured to keep the second transistor in an off state during the undershoot noise.

Abstract: A method of image data transmission in which when the transmission of programs is changed and a desired program has to be copied from the main server to the cache server, the copying is carried out in a modified order of priority so as to increase the efficiency. The controller 16 examines whether the video program inserted is “urgent” or not, and examines whether the video program being copied from the main server 4 to the cache server 5 is “urgent” or not. When “urgent”, the controller 16 examines whether or not the video program inserted has a higher priority than the video program being copied. When so, the controller 16 stops the copying and starts the copying of the video signal inserted.

Abstract: In a multi-layer interconnection structure, the wiring length is to be reduced, and the interconnection is to be straightened, at the same time as measures need to be taken against radiation noise. To this end, there is disclosed a semiconductor device in which plural semiconductor substrates, each carrying semiconductor elements, are bonded together. On each semiconductor substrate is deposited an insulating layer through which is formed a connection wiring passed through the insulating layer so as to be connected to the interconnection layer of the semiconductor element. On a junction surface of at least one of the semiconductor substrates is formed an electrically conductive layer of an electrically conductive material in which an opening is bored in association with the connection wiring. The semiconductor substrates are bonded together by the solid state bonding technique to interconnect the connection wirings formed on each semiconductor substrate.

Abstract: When nitride series III-V group compound semiconductor is manufactured by gas phase growing using starting material for a group III element, ammonia as a starting material for a group V element and hydrogen, the gas phase molar ratio of hydrogen to the total amount of hydrogen and ammonia (H2/(H2+NH3)) is specified to 0.3<(H2/(H2+NH3))<0.7, 0.3<(H2/(H2+NH3))<0.6 or 0.4<(H2/(H2+NH3))<0.5. A nitride series III-V group compound semiconductor can thus be manufactured with less non-emission center and of excellent crystallinity.

Abstract: An insulating member is used on or with a high-voltage probe that applies a voltage to the anode of a cathode ray tube during manufacture of the tube. If there are flaws in the frit seal of the tube, the probe produces arcing through the flaw into a grounded, conductive band disposed around the exterior of the frit seal. The insulating member is placed between the high-voltage probe tip and the grounded band around the frit seal. Consequently, the insulating member prevents electrical arcing external to the cathode ray tube between the high-voltage probe and the grounded band. Such arcing would otherwise interfere with the testing of the frit seal and could possibly damage the test equipment.

Abstract: High-voltage power supplies used in a Cathode Ray Tube (“CRT”) manufacturing process should be protected from residue, dust and other contaminants. This will prevent possible damage to the voltage power supply and danger to people and equipment that can result from operation of a dirty voltage power supply. A protective housing made of a non-conductive, insulating material is used to encase and protect the voltage power supplies used in a CRT manufacturing process. This protective housing protects those voltage power supplies from degradation or damage due to the dust, residue or other contaminants that arise from the CRT manufacturing process. A cooling system may be incorporated into the housing to manage thermal energy generated by the voltage power supply unit.

Abstract: A jig can be used to site-test the accuracy of multi-meters that are used to measure resistances in a cathode ray tube production line without having to remove those multi-meters from the production line or ship them to a third party service provider for the testing. The jig is a box of electronics that includes a variety of known resistance loads that can be selected and then measured by a multi-meter to test and/or calibrate that meter. The jig includes a number of known resistance loads, a device for selecting a particular resistance load and electric contacts for connecting a multi-meter to the jig so that the meter can measure the selected and known resistance load. By comparing the measured and known resistance values, the accuracy of the multi-meter is tested.

Abstract: A communication interface device includes a wireless Internet packet (IP) transceiver and a PCMCIA card electrically connected to the transceiver. Also, a universal serial bus (USB) connector is plugged into a hub that holds the PCMCIA card, with a cord extending from the USB connector and terminating in another USB connector. Accordingly, the device can be engaged with the PCMCIA bay of a user terminal or, if a user terminal has no PCMCIA bay, with a USB receptacle of the user terminal, to establish wireless communication. To simplify set-up, a CD containing all operating system versions of PCMCIA and USB drivers is engaged with the user terminal. The terminal's operating system is then automatically determined, and only the drivers associated with that operating system are loaded onto the terminal.
