摘要:
The present invention relates to a polyester film produced by melt-extruding a polyester composed of a dicarboxylic acid unit and a diol unit, wherein 1 to 80 mol % of the diol unit is a unit containing a cyclic acetal skeleton, and the polyester film has an in-plane retardation of 20 nm or less at a wavelength of 550 nm. The polyester film is an optically isotropic polyester film which is easily produced by an extrusion-molding method and has an economical advantage. The polyester film is useful for production of optical members or optical products such as phase difference films, protective films for polarizing plates, light diffusion films, lens sheets, anti-reflection films and optical information recording media.

摘要:
The electronic apparatus includes: a timer for measuring an elapse time duration under a component-disengaged state after detection of the disengaged state by the sensor; a copy controlling unit for making data stored in the recording unit to be copied in a storage unit of the information processing apparatus; and a deleting unit for deleting data stored in the recording unit. The copy controlling unit makes data stored in the recording unit to be stored in the storage unit of the information processing apparatus when the timer detects elapse of a first predetermined time duration, and the deleting unit deletes data stored in the recording unit when data stored in the recording unit is copied in the storage unit. This makes it possible to prevent loss of data stored in the recording unit of the electronic apparatus, and to improve data confidentiality, and to prevent confidential information leakage.
摘要:
The operating state of a computer is switched only when moving of the computer is detected. An information processing device has a detection unit, which detects, as a lifting action, a fact that an accelerated velocity has been kept applied in one direction for a given period of time, and a control unit, which executes a predetermined control operation that is associated with the lifting action detected by the detection unit. A lifting action detecting method has a detection step of detecting, as a lifting action, the fact that an accelerated velocity has been kept applied in one direction for a given period of time, and a control step of executing a predetermined control operation that is associated with the lifting action detected in the detection step.
