摘要:
A meta data set correlated with position information is acquired from a server via a communication interface unit (202) or a broadcast interface unit (201). A current position information acquisition unit (208) acquires the current position information and a content processing unit (203) outputs a content list matched with the search condition including the current position information from the meta data set. When a display list is generated according to the content list, a content display control unit (204) compares the content list to the display list. When they coincide, the meta data generates a display list without changing the display method and displays the search result on a browser unit (205) according to the display list generated by the content display control unit (204).

An image display whereby one can extremely easily know the current position of one's own vehicle and also grasp the actual situation around the current position of the vehicle, and with which the user gets highly satisfied. The image display includes a display device to display a photo picture on a prescribed reduced scale which is prepared based on photo data on a first scale that is read from a storage device in which photo data of two or more types in different scales to one area is stored, and a display switching device to conduct display switching according to a user's command to a photo picture on another reduced scale which is prepared based on photo data in a second scale that is different from the first scale.
摘要:
A data relay processing method where an available transmission band is partially reserved, partially assigned or partially exchanged between multiple communication terminals. Pieces of information are communicated between the multiple terminals. Such information includes a schedule of a term in which the transmission band is available, and a communication price that is charged to terminals in exchange for the usage of the transmission band. A schedule of transmission band usage and history of transmission band usage are utilized to efficiently reserve, assign or exchange the transmission band.
摘要:
There is provided a transmitting section for receiving program information representative of an outline and receiving condition of a receivable program and further receiving a program on the basis of the program information, and a zone-change determining section for detecting a change of the program information. The program selecting section causes the transmitting section to suspend program reception and to switch a communication port, on the basis of a determination of a change of program distribution area by the zone-change determining section. Due to this, the transmitting section is allowed to continuously receive the program so far received. This, in the case a program is provided at a communication port different based on each region, makes it possible to correctly receive a program even if moving traversing a region.
摘要:
When etching is performed with respect to a silicon-containing material by using a dry etching apparatus having a dual power source, the application of bias power is initiated before oxidization proceeds at a surface of the silicon-containing material. Specifically, the application of the bias power is initiated before the application of source power is initiated. Alternatively, the source power and the bias power are applied such that the effective value of the source power reaches a second predetermined value after the effective value of the bias power reaches a first predetermined value.
摘要:
A mask layer and a to-be-processed layer are irradiated with light to measure interference light formed of reflected lights from the mask layer and reflected lights from the to-be-processed layer. Thereafter, an interference component brought by the mask layer is removed from the waveform of the measured interference light, thereby calculating the waveform of the interference light brought by the to-be-processed layer. The thickness of the remaining to-be-processed layer is determined on the basis of the calculated waveform of the interference light and the thickness of the remaining to-be-processed layer is compared with a desired thickness thereof. In this way, an end point of processing on the to-be-processed layer is detected.
