    摘要： A wireless communication device 81 operates in either a ROD mode or a non-ROD mode. The non-ROD mode sets the state of the device to an active state that the device can perform wireless communication compliant with a first communication scheme with a communication destination device 82. The ROD mode: sets the state of the device to either the active state or a sleep state that the device can receive an activation instruction signal compliant with a second communication scheme requiring smaller electric power to receive a signal than the first communication scheme and cannot perform wireless communication compliant with the first communication scheme with the communication destination device; sets the state of the device to the sleep state when a predetermined sleep condition is satisfied; and sets the state of the device to the active state when the device receives the activation instruction signal.

    摘要： A packet interval (a time difference between sequentially received packets) in a certain previous time is calculated and a cumulative distribution function of the calculated packet interval is obtained. Meanwhile, a function value-corresponding to-flow end that is a boundary value of the cumulative distribution function to be considered as a flow end (timeout) in the range of a cumulative distribution function value is stored. From the cumulative distribution function obtained as described above, a value of a packet interval mapped to a cumulative distribution function value that matches the function value-corresponding to-flow end is set as a threshold. That is, the threshold is dynamically set based on a previous packet interval. Therefore, a packet stop period from a last packet reception time to a current time is measured, and it is detected as a flow timeout at a timing when the measured value is equal to or greater than the threshold.

    摘要： An optical head is provided with a light source for emitting a first laser beam having a first wavelength shorter than 430 nm, a two-wavelength light source for emitting a second laser beam having a second wavelength equal to or longer than 430 nm, a flat beam splitter in the form of a single plate for reflecting the first laser beam emitted from the light source, a wedge prism in the form of a single plate for reflecting the first laser beam reflected by the flat beam splitter and transmitting the second laser beam emitted from the two-wavelength light source, and an objective lens for focusing the first laser beam reflected by the wedge prism on an information recording surface of a BD. The light source is arranged such that the optical axis of the first laser beam emitted from the light source is inclined with respect to that of the second laser beam emitted from the two-wavelength light source. By this construction, the miniaturization of the optical head can be realized.

    摘要： It is intended to provide an optical fiber-cutting method and an optical fiber-cutting machine, by which an optical fiber can be cut smoothly and perpendicularly to the axis of the optical fiber. A ferrule 21 is held by a holder 14 which is supported in a slantingly movable fashion relative to the main body 12 of a cutting machine 11, and an end portion of the optical fiber 20 projecting from an end face of the ferrule 21 is held by a clamp 16 to apply a pulling force to the optical fiber. The holder 14 is slanted to bend the optical fiber 20, and a cutting blade 28 is moved in an arc line along the circumference of a basal portion at the inner side of the bending portion of the optical fiber 20 while butting the cutting blade 28 to the optical fiber 20, to make a cut 20a of an arc shape, and then the holder 14 is slanted toward the direction opposite to the above direction to bend the optical fiber 20 toward the direction opposite to the above direction, thereby cutting the optical fiber 20.
