Title: Optical disk drive
Inventor: OKADA YASUSHI
IPC: G11B7/125
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To improve operation efficiency, prolong a life of a laser diode and improve reliability, by sampling a track by a preceding sub beam, and controlling an output of a laser light so that the amount of a main beam becomes optimum in a three-beam type optical disk drive. SOLUTION: A state information on a track accessed by a sub beam preceding by one cycle to a main beam among three beams is detected by a photodetecting element 11. A condition whether the track at the position is dirty is judged from the amount of the detected light. A current for supplying the amount of the main beam from a driver 13 of a laser diode LD to a laser diode LD 14 in accordance with an output of the photodetecting element 11 corresponding to the sub beam is controlled thereby to adjust a laser output to be an optimum value. In this manner, the amount of the main beam reaching the track sampled by the sub beam can be optimum, whereby an optical disk is recorded, reproduced well without being influenced by the dust and dirt of the optical disk.

IPC: H01S5/00
Filed: 1981-12-25
Abstract: PURPOSE:To prevent the generation of noises by a semiconductor laser by incorporating a reflecting mirror into a package supporting the semiconductor laser and stably maintaining single longitudinal mode oscillation. CONSTITUTION:A semiconductor laser chip 1 is supported by a mount 2. The mirror 3 is set up in parallel onto the mount 2 while being opposed to one laser projecting end surface 11 of the laser 1. One part of laser beams reflected by the mirror 3 passes through the end surface 11 again, and is fed back into a into a laser resonator. When a distance d between the end surface 11 and the mirror 3 is kept within the range of 10mum-50mum, only a specified single longitudinal mode in which the resonator mode of an optical resonator formed by the end surface 11 and the reflecting mirror 3 and the resonator mode of the laser 1 overlap is oscillated stably even when a temperature changes or reflected light is fed back from the end surface of an external optical element, thus inhibiting the generation of noises.

Filed: 1985-09-24
Abstract: PURPOSE:To improve the guidance accuracy by reducing a side lobe gain of an antenna corresponding to an incident angle, and tracking a target of a low altitude. CONSTITUTION:A speed vector of a missile is derived by executing an arithmetic processing 31 of an angular velocity and an acceleration of the missile, which are obtained from a rate gyro 20 and an accelerometer 30 which are loaded on the missile. On the other hand, a distance and a direction of a target are known by a radar range finder 32 and an antenna angle control system 21. By bringing these information and speed vector to an arithmetic processing 33, a speed vector, etc. of the target are obtained, and furthermore, by executing an arithmetic processing 34, an incident angle PSIM to an antenna 3 of a radio wave is derived. A side lobe gain of the antenna 3 is suppressed by operating an antenna envelope control mechanism 35 in accordance with the angle PSIM. In this way, even the target of a low altitude can be tracked by varying adap tively an envelope of the antenna 3 so that a clutter power having a frequency transition of the vicinity of a Doppler frequency transition of the target is suppressed, and the guidance accuracy is improved remarkably.

Title: Level indicator
Inventor: HENKU UIREMU ANDORE BEGASU
IPC: G01R13/00
Filed: 1985-09-24
Abstract: For displaying the ratio in decibels between the instantaneous value and the maximum value of a digital signal a rectified digital signal is serially applied to an input (4) of a level indicator. This indicator comprises a shift register (10) which, in the case of an indicator with a resolution of 2 dB, comprises three series-connected flip-flops (11, 12, 13). The input (M) of the first flip-flop (11) is connected to the input (4) of the level indicator. The flip-flops (11, 12, 13) each comprise an output (QA, QB, QC), which like the input (M) of the first flip-flop (11) are connected to the inputs of a combination circuit (20). The output (QC) of the last flip-flop (13) is also connected to the input of a read-enable circuit (15). For each bit of the digital signal which is loaded into the shift register (10) the combination circuit (20) generates a number from the signals on the outputs (QA, QB, QC) and the input (M) of the shift register (10), which number indicates how many times an amount of 2 dB should be subtracted from the said ratio. In an adder (30) this amount is added to the previous amount and the sum is applied to a memory (40) whose contents is transferred to a read-out device (50) at the instant at which the read-enable circuit (15) supplies an output signal.
