After a metal cap layer is laminated on a semiconductor laminated structure, a waveguide ridge is formed, the waveguide ridge is coated with an SiO2 film, and a resist is applied; then, a resist pattern is formed, the resist pattern exposing the surface of the SiO2 film on the top of the waveguide ridge, and burying the SiO2 film in channels with a resist film having a surface higher than the surface of the metal cap layer of the waveguide ridge and lower than the surface of the SiO2 film of the waveguide ridge; the SiO2 film is removed by dry etching, using the resist pattern as a mask. The metal cap layer is removed by wet etching, and a p-GaN layer of the waveguide ridge is exposed to form the electrode layer.

A fault tolerant (FT) computer system includes a first system; and a second system configured to operate in synchronization with the first system. Each of the first and second systems includes a CPU; and a routing controller connected with the CPU. The first system includes a first I/O device as an activist I/O device, and the second system includes a second I/O device as a standby I/O device. The routing controller controls a routing between the CPU and the first I/O device and the second I/O device. When a fault has occurred in the first I/O device, the routing controller in said first system routes a request data a request data received from the CPU and destined to the first I/O device, to the second I/O device.
摘要:
A video content creating apparatus includes a computer. The computer registers photographic image data input from a photographic input device and meta-information set in relation to the data in a database. After retrieving photographs based on the meta-information, the apparatus selects the photographs to be used for a reminiscence video and decides the reproduction order of the photographs. After registering a BGM playlist, the apparatus reproduces the photographs and BGM for creating the reminiscence video. If there are any regions, the apparatus displays the regions on a monitor while aligning them in sequence according to the meta-information on them. Upon completion of generation (rendering) of a series of reminiscence video contents, the apparatus creates the reminiscence video by saving the rendering results in Flash movie format, for example.
摘要:
The olefinic polymer characterised in that the n-decane-soluble content thereof is 10% by weight or less and the content of a ligand having a cyclopentadienyl structure is 5 ppb by weight or less. The process for producing an olefinic polymer is a process of producing an olefinic polymer by (co)polymerizing olefins in a gas phase using a fluidized-bed reactor, the process comprising: a polymerization step of (co)polymerizing the olefins with allowing a saturated aliphatic hydrocarbon to exist in a concentration of 2 to 30 mol % in the fluidized-bed reactor and a ligand removing step involving a step of bringing the resulting (co)polymer into contact with a ligand-remover and a step of heating said (co)polymer which has been brought into contact with the ligand-remover.

摘要:
A first dielectric wall and a second dielectric wall in which hollow alumina cylindrical columns are arranged in layers so that axial centers of the alumina cylindrical columns describe planar triangular lattice arrays, are opposed to each other, and are parallel to air interposed between them. Metal plates are opposed to each other and have end faces of the alumina cylindrical columns interposed between and connected to the metal plates. The first and second dielectric walls and the metal plates are bonded to one another, as a high-frequency waveguide with reduced radiation loss, and that is inexpensive and low in transmission loss.
