摘要： An object of the invention is to prevent damage or performance degradation of an optical component constituting a second optical system, and suppress degradation of the recording/reproducing performance of an optical pickup device. A first laser light source 1 emits a first light beam having a first wavelength. A first optical system 17 guides the first light beam to be emitted from the first laser light source 1 to a first optical disc. A DVD integration unit 11 emits a second light beam having a second wavelength different from the first wavelength. A second optical system 18 guides the second light beam to be emitted from the DVD integration unit 11 to a second optical disc different from the first optical disc in recording density. A filter 20 is disposed at a position capable of blocking incidence of an unwanted light beam having the first wavelength derived from the first optical system 17 into an optical component constituting the second optical system 18 to block the first light beam having the first wavelength.

摘要： In an optical head device which performs recording or reading of data in/from a high-density optical disc using an objective lens with a large NA, a saw-tooth shape diffraction element is used for also performing recording or reading of data in/from a conventional optical disc, such as DVD, CD, or the like. A step difference that produces an optical path length for blue light which is equal to or longer than the wavelength of the blue light and optical path lengths for red and infrared light which are shorter than the wavelengths of the red and infrared light is utilized so as to exert an inverse action on the blue light to those exerted on the red and infrared light. The effect of increasing the working distances for CD and DVD enables multiple compatibility. The above optical element is integrally combined with the objective lens to perform a tracking servo following operation.

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： 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.
