Abstract: Provided is an electrophotographic belt of an endless shape including a substrate, wherein the substrate contains a polyimide resin and carbon nanotubes, wherein a content of the carbon nanotubes in the substrate is 15 vol % or less with respect to a total volume of the polyimide resin, wherein the substrate has a tensile strength of 200 MPa or more in each of a peripheral direction thereof and a direction perpendicular to the peripheral direction, and wherein the substrate has a thermal conductivity of 0.9 W/(m·K) or more in a thickness direction thereof.

Abstract: A communication terminal device records voice data indicating a voice input during a call in memory (S2), and upon detecting that a proximity of a user's head to the communication terminal device has ceased to be detected (S3 and S4; YES), recognizes an utterance after a time point a predetermined period of time prior to a time point at which a proximity of the head to the communication terminal device has ceased to be detected, based on voice data recorded in the memory (S5). Upon detecting that a predetermined keyword has been recognized, and that no proximity of the head to the communication terminal device is detected, the communication terminal device terminates the call (S9).

Abstract: Portable communication terminal apparatus includes a function of performing communication for a call. Also, communication terminal apparatus includes a proximity sensor for detecting that an object (head of a user) exists in proximity to the communication terminal apparatus, and an acceleration sensor for measuring a motion state of the communication terminal apparatus. Communication terminal apparatus performs call ending processing for ending a call if, during the call, a transition is made from a state in which the presence of the object is detected by the proximity sensor to a state in which the presence of the object is not detected, and thereafter the motion state detected by the acceleration sensor satisfies a predetermined condition. The condition of the motion state is determined, for example, based on an operation consciously performed by the user, such as an operation of shaking communication terminal apparatus.

Abstract: A communication terminal device is a mobile communication terminal device that carries out communication for voice calls. In the case where an incoming voice call is received, the communication terminal device measures an orientation and a displacement of the device itself, and determines whether or not a condition occurring when a user picks up the device in his/her hand is met. After determining that the condition occurring when a user picks up the device in his/her hand is met, in the case where the communication terminal device determines that the device is detected as being near the user's head area and furthermore determines that an utterance from the user has been detected while the user's head area is detected as being near, the device carries out a notification processing for notifying the user that a response to the incoming call will be made, after which the response to the incoming call is made.

In the case where it is determined that the condition occurring when the user picks up the device in his/her hand is met, and in the case where it has been determined that the user's head area has been detected as being near, the communication terminal device specifies a voice call partner on the basis of the orientation measured before the head area was detected as being near or while the head area was detected as being near. Then, when a tap operation performed by the user is detected, the communication terminal device performs a notification processing for making a notification of the specified voice call partner, and then makes an outgoing call to the partner.

Abstract: Acquiring means acquires relevant information (for example, information indicative of an amount of processing that has been performed relative to the content based on a user's operation) relevant to content. Selecting means selects one or more content from among a plurality of content corresponding to a plurality of items of display information displayed on first display means, based on relevant information acquired by acquiring means for each of the plurality of content. Display control means causes second display means to display the one or more content selected by selecting means.
