摘要:
An amine derivative represented by the following general formula (1) and exhibiting a temperature difference of 30° C. or more as defined by the difference of [decomposition temperature (° C.) minus sublimation temperature (° C.)]: wherein R1 and R2 independently represent a substituted or unsubstituted C6-40 aryl or C5-40 heteroaryl group; and R3 and R4 independently represent a hydrogen atom, a straight-chain, branched or cyclic C1-18 alkyl or C1-18 alkoxy group, or a substituted or unsubstituted C6-40 aryl or C5-40 heteroaryl group, provided that R3 and R4 may form together a cyclic hydrocarbon group. The amine derivative is useful as an organic electroluminescent material.

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.

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.

An electronic device includes: a DC power source which supplies a first DC supply voltage; a DC voltage converter which is enabled or disabled in response to a first control signal, and which converts the first DC supply voltage into a second DC supply voltage different from the first DC supply voltage, when the DC voltage converter is enabled; a switch which selects and supplies either the first DC supply voltage or the second DC supply voltage as an output in response to a second control signal; a DC voltage regulator which is enabled or disabled in response to a third control signal, and which converts the DC supply voltage selected by the switch into a third supply voltage lower than the selected DC supply voltage when said DC voltage regulator is enabled; a control unit which provides the second control signal to the switch; and a loading which utilizes the third DC supply voltage. While the loading is operating intermittently, the control unit provides to the DC voltage converter the first control signal for disabling the DC voltage converter, provides to the switch the second control signal for selecting the first DC supply voltage, and provides to the DC voltage regulator the third control signal for enabling the DC voltage regulator.

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 portable information device, a power saving mode switching method, and a recording medium in which a power saving mode switching program is stored, for efficiently suppressing power generation peaks. In an information device having a component (1) such as a processor and a component (2) such as a magnetic disk device, it is detected whether it is the peak power generation condition or the peak power completion condition on the basis of access information to the component (2), and a power mode change request is given to a power mode changing means (4); and the power mode changing means (4) changes over the component (1) such as the processor from a normal power mode to a power saving mode where the operating voltage is reduced, the clock frequency is reduced, or the like when the peak power generation condition is detected, and changes over it from the power saving mode to the normal power mode when the peak power completion condition is detected.

An information processing apparatus (100) includes a main unit (110) including a keyboard and having a generally rectangular major surface, and includes a display device (130) including a display screen and having a generally rectangular major surface. A bottom of the major surface of the display device can be selectively placed in a first position in which the bottom extends substantially along a first side of the major surface of the main unit, and a second position in which the bottom extends substantially along a second side of the major surface of the main unit that is substantially perpendicular to the first side. The information processing apparatus (100) further comprises power supply and information communications connectors in the main unit on a third side of the major surface of the main unit that is opposite and substantially parallel to the second side. The connector is connectable through another connector on a car docking station.

摘要:
A continuous vacuum carburizing process carburizes material such as a steel wire 7 with a carbon content equal to or less than a desired carbon content by passing it under reduced pressure continuously through a carburizing atmosphere 5 with constant pressure and constant gas composition. A continuous vacuum carburizing apparatus for carrying out this process has at least one furnace core tube 1, 11, or 12 and a feeding/taking-up mechanism 13, 14 for the steel wire 7 in a vacuum container 1. Carburizing medium gas is supplied to the furnace core tube 1 via pipes 2, 4 to form the carburizing atmosphere 5. A heater 10 heats the furnace core tube 1, thereby activating carbon of the carburizing medium gas. In this way, material having a small thickness of, for example, 0.02 mm to 3 mm is carburized with less variation in the amount of carburization and no surface oxidation or sooting.
