Title: Optical receiver using apd
Inventor: CHIYUUZENJI TOMOHIRO
IPC: H04B10/572
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To prevent an APD from being applied with bias voltage and damaged by the input of an abnormal signal in an optical receiver using APD. SOLUTION: An optical signal is given to a photocoupler 1, where the signal is distributed into a main signal and a monitor signal, the main signal is given to a timing extract circuit 9 and an identification recovery circuit 8 via a preamplifier 6 and an AGC amplifier 7. The AGC amplifier 7 provides an output of a feedback signal equivalent to an input signal level to be fed back as a bias voltage of an APD 2 via an APD bias circuit 5. A level detector 4 detects a monitor signal so as not to give damage to the APD 2 even on the occurrence of an AGC excess bias voltage due to a very small optical signal level and an excess optical current of the APD 2 due to excess optical signal level, and an APD bias circuit 5 is controlled against excess or deficient optical signal input so as to fix the bias voltage to a voltage not giving damage to the APD.

IPC: G11B17/22
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to speed up the announcement of the effect that an empty tray is erroneously selected by detecting the presence of a disk on a tray facing a recording and reproducing section, once storing the information on the presence or absence of the disk and actuating a tray drive mechanism upon detection that there is no disk on the tray from the information on the presence or absence of the disk in a memory when a manipulation signal is received. SOLUTION: When the tray 4 arrives at a position of EXTRA upon confirmation that the tray 4 arrives at the EXTRA position, i.e., that a switch SW2 is on and a switch SW3 is off, the lapse of the prescribed time is decided. When the time within the prescribed time is attained, a force OPEN operation is ended by deciding that the tray 4 can move smoothly between a HOME position and the EXTRA position. When the prescribed time elapses, the user's attention is aroused by judging that there is a hindrance in the forward and between movement of the tray 4. The number of repetition times of the retreat and advance of the tray 4 is then checked and the corresponding processing is executed by the number of the repetition times and the display to this effect is carried out.

Abstract: PURPOSE:To eliminate the congestion state of a CPU of a protocol control section early and to prevent the destruction of the content of a transmission buffer by stopping tentatively the transmission request of a line control section with respect to a protocol control section when the congestion state of the protocol control section is detected. CONSTITUTION:A protocol control section A2 monitors the state of a CPU 2 and a transmission buffer 4 in the state of communication and when the CPU 2 reaches the congestion state or the queue of the transmission buffer 4 reaches a prescribed value or above, a transmission request reception disable signal is sent to a line control section A1. Upon the receipt of the transmission request reception disable signal, the line control section A1 stops the transmission of the transmission request signal to the protocol control section A2 and stores its content to the transmission buffer 9. Upon the detection of the decrease in the congestion state of the CPU 2 or the number of queues of the transmission buffer reaching a prescribed value or below, the protocol control section A2 sends the transmission request reception disable signal to the line control section A1. When the line control section A1 receives the transmission request enable signal, the line control section A1 restarts the transmission of the transmission request signal to a protocol control section A2 and when the queue exists in the transmission buffer 9, the content is sent to the line control section A1.

As the roller 44 is supported at the same position to a pitch circle of a gear 42, the roller 44 moves along the pitch circle. The center shaft for the roller 44 makes an epicycloid motion on the pitch circle of the solar 43 and the roller 44 rotates within the groove 48 of an output arm 47. Therefore, the output arm 47 also rotates an output shaft 24.
