  • Publication number: 20040107299
    Abstract: Disclosed is a home gateway apparatus having an in-home telephone network switching function, and an embodiment method thereof. The home gateway apparatus offers high-speed access to an access network using xDSL (“x” variety of Digital Subscriber Line) protocols such as ADSL or VDSL and an in-home network using VoIP (Voice over Internet Protocol) functions and a variety of protocols, and has xDSL and VoIP interfaces with PSTN (Public Switching Telephone Network) and VoIP functions that enable easy installation and application in different in-home telephone network environments. Using this, in-home VoIP/POTS (Plain Old Telephone Service) networks and high-speed HomePNA networks can be freely constructed through a single home gateway, bypassing the existing two-wire or four-wire in-home telephone lines.

  • Publication number: 20030188568
    Abstract: A gas sensor 10 includes a sensor element 1 having a specific function, and a housing 5 containing the sensor element 1 therein and including a specific thread section 2 and a sealing surface 4 which forms a sealing section 3 together with an installation section at a position deeper than the thread section 2 in a direction in which the sensor element 1 is inserted. Release torque at 850° C. (1123 K) in the case where the housing is screwed into the installation section is 9 N·m or more, and an estimated value X1 of a gap formed between the sealing surface 4 and the installation section at 850° C. (1123 K) calculated according to a specific equation is 31 &mgr;m or less.

  • Patent number: 5812483
    Abstract: An integrated circuit memory device includes a memory cell array including a plurality of odd and even numbered subword lines extending therethrough. A predecoder receives a row address and generates a plurality of predecoding signals in response thereto, and a row decoder receives the row address and generates a word line signal in response thereto. A first driver block includes a first plurality of word line drive circuits adjacent the memory cell array wherein each of the word line drive circuits of the first plurality is connected to a respective odd numbered subword line of the memory cell array. A first plurality of subword line drive circuits drive the respective odd numbered subword lines responsive to odd numbered predecoding signals and the word line signal.

  • Patent number: 5658062
    Abstract: A light amount controlling apparatus includes a light source for producing light and a light source driver for driving the light source. A zoom lens unit includes a zoom lens for varying an angle of projection of the light, and a zoom lens position detector detects a position of the zoom lens. A memory stores control data corresponding to the position of the zoom lens and a memory controller reads the control data from the memory according to a detected value of the zoom lens position of the zoom lens position detector. A controller controls the light source driver to vary an amount of light projected from the light source in accordance with the control data output from the memory controller.
