A silicon nitride-melilite composite sintered body in accordance with the invention includes silicon nitride and a melilite Me2Si3O3N4, where Me denotes a metal element combining with silicon nitride to generate the melilite. The silicon nitride-melilite composite sintered body contains Si in a range of 41 to 83 mole percent in Si3N4 equivalent and Me in a range of 13 to 50 mole percent in oxide equivalent. The silicon nitride-melilite composite sintered body has an average thermal expansion coefficient that is arbitrarily adjustable in a range of 2 to 6 ppm/K at temperatures of 23 to 150° C. The silicon nitride-melilite composite sintered body has a high Young's modulus, a high mechanical strength, and excellent sintering performance. A device used for inspection of semiconductor in accordance with the invention utilizes such a silicon nitride-melilite composite sintered body.

An electronic apparatus has a storage part to store a plurality of screen information, including incoming call screen information, a display part to display the screen information, and an output control part to output to an outside of the electronic apparatus arbitrary screen information that is to be output to the outside, of the screen information stored in the storage part, and to display the arbitrary screen information on the display part, when an external output function is set to an ON state. The output control part continues outputting the arbitrary screen information to the outside and displays on the display part the incoming screen information stored in the storage part, when an incoming call is received in a state where the external output function is set to the ON state.
摘要:
In etching of silicon nitride with a phosphorus type, if etching is carried for a long time, silicon oxide tends to precipitate, and it has been impossible to constantly carry out the etching for a long period of time.By an etching method for silicon nitride using a composition comprising a phosphorus compound, a boron compound, a silicon compound and/or their fluorides thereof, there will be no precipitation of silicon oxide even when the composition is used for a long time. It is particularly preferred to further add nitric acid and/or a nitrate, whereby stability of selectivity will be increased.

An information terminal apparatus includes a memory and a processor. The memory stores information indicating a front operating system. The processor runs a first virtual machine that executes a first operating system. The processor runs a second virtual machine that executes a second operating system. The processor controls user interface of the information terminal apparatus by executing the front operating system. The processor detects, by referring to the information stored in the memory, that the front operating system is changed from the first operating system to the second operating system. The processor notifies, upon the detection, the first virtual machine of a first notification indicating that the user interface stops. The processor notifies, upon the detection, the second virtual machine of a second notification indicating that the user interface restarts.

A mobile phone terminal receives current position information thereof from a public wireless base station, and stores the current position information. The mobile phone terminal reads a profile name corresponding to the position information from a public wireless base station-WLAN profile association table, and sets the WLAN profile as a scan profile. Then, the mobile phone terminal scans the WLAN profile when the mobile phone terminal is located outside the WLAN service area.

There is provided an information processing apparatus with a double-sided operable keyboard, capable of executing desired application processing even in the case where a keyboard is folded and keys to be normally operated are directed to a reverse side (e.g., a display apparatus side or a lower side) with respect to a user. The information processing apparatus includes a display apparatus and a keyboard apparatus. The keyboard apparatus is foldable so as to cover a lower part or a portion of a display region of the display apparatus, and at least one function key assigned arbitrary applications are provided on a bottom surface of the keyboard apparatus. Furthermore, the information processing apparatus includes a keyboard position detecting part for detecting a relative position of the keyboard apparatus with respect to the display apparatus, and switches effective keys between keys on an upper surface of the keyboard apparatus and keys on the bottom surface of the keyboard apparatus in accordance with the relative position of the keyboard apparatus.
摘要:
A mobile terminal device receives information related to a push email service from a mail server, a calendar server, and a phone book server that provide the push email service via a wireless communication network. The mobile terminal device stores therein setting information that indicates whether the information related to the push email service is received at the time of the standby state. Furthermore, the mobile terminal device determines whether to shift the state of the mobile terminal device to a standby state. If the mobile terminal device determines that the mobile terminal device will shift its state to a standby state, the mobile terminal device transmits, on the basis of the stored setting information, a setting notification that instructs the stopping of the push email service to the mail server, the calendar server, and the phone book server.
摘要:
A radio communication method for a radio communication device having a first communication unit and a second communication unit includes determining whether a connection between the radio communication device and a local-area radio network is in a difficult state while the radio communication device is connected to the local-area radio network by the second communication unit, obtaining position information through the started first communication unit, reading out communication set information recorded with the obtained position information that records communication set information, and the position information obtained from the base station at a position connectable to the local-area radio network associated with the communication set information relating with each other, and detecting a connectable local-area radio network based on the read communication set information when the communication determination unit determines that a connection between the radio communication device and a local-area radio network is in the difficult state.
