Abstract:
A relation between a light input power monitor value of an optical transmission signal before passing through a fiber and an input signal amplitude monitor value is recorded in advance in a storage device. Next, actual optical-transmission-waveform is inputted into an optical receiver module, and then comparisons between a light input power monitor value and an input signal amplitude monitor value, and respective monitor values in the case without having the waveform distortion as described above are performed in an operation device to calculate a waveform distortion value. According to the waveform distortion level calculated herein, an optimum threshold value and an optimum phase adjusting value, at which receiver sensitivity is maximized, are calculated in the operation device to control a threshold-value adjusting circuit and a phase-value adjusting circuit, thereby a threshold value and a phase value that are optimum for an input distortion level can be established.
Abstract:
To provide economical high-speed optical communications through an optical module a silicon substrate with a ball lens and semiconductor luminescence element mounted thereon, and a laser driver IC are provided. A silicon subassembly includes a silicon substrate with a pyramidal cavity etched into the substrate near its edge. A ball lens is precision-mounted in the pyramidal cavity by bonding it at multiple points. This provides a high-strength connection and a small, inexpensive silicon substrate. Also provided on the silicon substrate is a semiconductor luminescence element and a slit on the opposite side of the ball lens. The slit enables collimated light emitted from the ball lens to be optically coupled without being blocked or reflected by the substrate. The semiconductor luminescence element and its laser driver IC are placed in close proximity to each other, and ribbon wires are kept short (approximately 300 &mgr;m) to reduce signal line impedance mismatch for high-speed transmission.
Abstract:
A signal processing circuit which enables an error bit to be set simply without causing an increase in the size of the circuit even if the packet size is changed and which enables realization of stable operation without the system stopping even if the value of the time stamp is impossible. A pre-reception processing circuit decides if a received packet is normally continuous or discontinuous from data in the DBC region of the CIP header. When deciding it is discontinuous, it sets an error bit ERM allocated to one bit of the upper significant 7 bits of the source packet header to “1”, and writes this in an FIFO. A post-reception processing circuit, when reading from the FIFO, outputs the data stored in the FIFO to the application side when the error bit ERM is “0” and resets the error bit and outputs a dummy error packet when the error bit EMR is “1”.

Abstract:
In a magnetic rotor, a rotatable shaft is received through a holder. A positioner is made of a magnetic material and is fitted into at least one of an outer peripheral wall of the rotatable shaft and an inner peripheral wall of the holder to position the holder relative to the rotatable shaft in a circumferential direction. An annular magnet is fixed to the holder and surrounds the rotatable shaft. The annular magnet has two magnetic poles of different polarities, which are magnetized in a magnetization direction that coincides with a radial direction of the annular magnet. The positioner is displaced around a rotational axis of the rotatable shaft from the magnetization direction of the annular magnet by about 90 degrees in the circumferential direction.
