Abstract:
Provided are: a hermetically-enclosed tank that is filled with insulating gas; a blocking unit that is provided within the hermetically-enclosed tank and is configured with a movable arc contact and a fixed arc contact opposing each other; a plurality of energizing units, within the hermetically-enclosed tank, that are provided around the blocking unit about its axial line as a center and located away from each other; and a fixed-side auxiliary conductor that is provided between a gas space which stores the energizing units and a gas space on the side of the fixed arc contact. A communication hole is formed on the fixed-side auxiliary conductor so as to communicate the gas space provided between the energizing units with the gas space.
Abstract:
An outer peripheral wall surrounds a heating chamber that communicates with an arc chamber through an opening that separates fixed contacts from each other in a circumferential direction. The outer peripheral wall includes a heat-resistive cylindrical heat-flow receiving wall portion that is arranged at a position opposed to the opening in a radial direction, and a cylindrical wall portion that is connected to the heat-flow receiving wall portion in a direction of a center axis and also connected to a fixed-side energizing member at its one end on the opposite side to where the wall portion is connected to the heat-flow receiving wall portion, and is made of an insulating material. With this configuration, the outer peripheral wall surrounding the heating chamber can be protected from damage and heat deterioration due to the influence of hot gas.
Abstract:
A control device is provided for controlling a light emission device. The control device includes a light metering unit configured to acquire respective light metering values from a plurality of light metering regions. The control device further includes a correction unit configured to correct information about a light metering value of a target region based on a result of comparison between the light metering value of the target region and the light metering value of the light metering region at the periphery of the target region among the plurality of light metering regions, the result being acquired by the light metering unit allowing the light emission device to perform pre-flashing. Also, a calculation unit is provided which is configured to calculate a main light emission amount of the light emission device based on the information about the light metering value corrected by the correction unit.
Abstract:
A mechanical-puffer-type arc-extinguishing chamber includes a fixed main contact, a movable main contact that moves on an opening-and-closing axis in a connectable and disconnectable manner to and from the fixed main contact, and a mechanical puffer chamber that is provided in the movable main contact and blows compressed insulation gas to an arc. A thermal-puffer-type arc-extinguishing chamber includes a fixed contact, a movable contact that moves on the opening-and-closing axis in a connectable and disconnectable manner to and from the fixed contact, and a thermal puffer chamber in which compressed insulation gas is blown to the arc. The mechanical-puffer-type arc-extinguishing chamber and the thermal-puffer-type arc-extinguishing chamber are arranged in series on the opening-and-closing axis, and two breaking portions are electrically connected in series.
Abstract:
A duplexer module prevents a transmission signal and a reception signal in the same band from interfering with each other. The duplexer module includes a transmission line, a reception line, and an antenna common line. In addition, the duplexer module includes a plurality of mounting electrodes arranged along the four sides of an outer edge of a mounting surface of a multilayer substrate. The fourth mounting electrode defining a monitoring port is disposed on a side different from a side on which each of the first mounting electrode defining a transmission port, the second mounting electrode defining a reception port, and the third mounting electrode defining an antenna port is disposed. The fourth mounting electrode defining the monitoring port is a mounting electrode used to output a signal of the monitoring line through which a portion of electrical power is transmitted from the transmission line.

Abstract:
The time required to transcode an encoded image signal to an image signal encoded by a different encoding method is reduced.Disclosed herein is a transcoder comprising: picture selector 4 which extracts specific types of pictures (I- and P-pictures) from a first image signal (MPEG2 stream) and generates a subset of the first image signal; a first decoder 5 which decodes the subset image signal; and a first encoder 7 which encodes the decoded image signal to a second image signal (MPEG4 stream). The picture selector 4 uses the extracted pictures to generate the subset image signal with a reduced effective length.
Abstract:
A gas circuit breaker is provided, avoiding change in the position of a cover member and without weakening of the blow of gas to the arc in an arc discharge cavity even when a surface of the cover member in contact with the arc discharge cavity is damaged. The gas circuit breaker includes a contact ring, a holder attached to the contact ring, and extending to a path of arc-extinguishing gas that extinguishes an arc, and an electrically insulative cover member attached to the holder.

Abstract:
An apparatus for acquiring an i-bit digital code by a first stage AD conversion and a j-bit digital code by a second stage AD conversion includes a comparing unit which compares a reference signal and an analog signal in the first stage AD conversion; and an amplifying unit for outputting an amplified residual signal acquired by amplifying a difference between the analog signal and an analog signal corresponding to the i-bit digital code. The comparing unit compares the amplified residual signal and the reference signal in the second stage AD conversion.
