Title: Frequency stabilized semiconductor laser driver
Inventor: UEDA TOSHITSUGU
IPC: H01S5/068
Filed: 1989-03-17
Abstract: PURPOSE:To narrow the band of light spectra and stabilize a frequency by a method wherein the output light of a semiconductor laser is applied to an absorbing cell and a Fabry-Perot interferrometer and the semiconductor laser is controlled by a signal obtained by applying the transmitted light intensity signal of the absorbing cell to a low-pass filter and a signal obtained by applying the transmitted light intensity signal of the Fabry-Perot interferrometer to a high-pass filter. CONSTITUTION:The output light of a semiconductor laser 1 is divided into four lights by half-mirrors 5, 6 and 7 and the lights are applied to a Fabry-Perot interferrometer 14, an absorbing cell 8 and a photodetector 17 and also outputted to the outside. The high frequency component of the output of a first photodetector 11 which detects the transmitted light intensity of the absorbing cell 8 is cut off by a low-pass filter 12 and the low frequency component of the output of a second photodetector 15 which detects the transmitted light intensity of the Fabry-Perot interferrometer 14 is cut off by a high-pass filter 16. The semiconductor laser 1 is controlled by the summation signal of those output signals. With this constitution, noise produced by the absorbing cell 8 and the influence of the fluctuation of transmission characteristics caused by the fluctuation of the distance between the semi-transmitting mirrors of the Fabry-Perot interferrometer 14 and the refractive index of the air can be avoided.

IPC: G11B21/10
Filed: 1988-03-22
Abstract: PURPOSE:To prevent the overlap of a recording signal and the miserasing of the recording signal of an adjacent track by measuring the slippage of the peak position of the envelope of a signal in a track and an absolute track position and correcting the stoppage position of a magnetic head on the track to be recorded by this slippage. CONSTITUTION:In case of there being the track recorded in the past on a video/ floppy the positioning position of a magnetic head 2 to be positioned at an absolute track position on the other track is corrected by using the difference (slippage) in the absolute track position of the recorded track (reference track) stipulated for by the steel/video/camera on which the video/floppy thereof is loaded. The detecting process of said slippage on the reference track is by the following method. (1) The slippage detection is performed in a track/reserch and the detected slippage is stored in a memory. (2) The slippage of the recorded track adjacent to the track to be recorded is detected on each recording process.

Title: Simultaneous transmission device/method
Inventor: CHEN BRIAN
IPC: H04J9/00
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To increase the convenience of a simultaneous transmission system between an FM signal and a digital modulation carrier by selecting carriers inserted into an FM band in a specified order. SOLUTION: A module 116 analyzes the interference of emulated transmission while the pre-cancellation effect of the sub-set of the carriers to the FM signal is considered. The module 116 calculates the value of γaggregate , which is caused by the FM signal by the sub-set of the carriers and shows deterioration as a whole based on interference analysis. It is decided whether the value exceeds the value of γmax or not. When it does not exceed the value, the module 116 decides whether a pair of final carriers is added or not to the sub-set. In such a case, a control channel transmitting information identifying the selected pair of carriers to a receiver changes a pair of carriers selected by the module 116 at every frame. A data bit showing control information is generated by a control channel processor 119.

Title: Coincidence detection circuit
Inventor: YASUDA SADAHIRO
IPC: G06F7/04
Filed: 1988-03-18
Abstract: PURPOSE:To suppress the number of comparators which require the detection of plural data values by providing a register to perform the bit designation of coincidence detection data. CONSTITUTION:In a detection data storage register 2, (5) or (D) is stored as detection data, and (7) is stored in a detection effective bit register 4 as effective bit designation data. At this time, since the content of the register 4 is (7), the comparison function of the fourth bit of the comparator 31 is nullified. Next, address information to be transferred to a BUSA is stored in a register 1 for storing data to be detected, and coincidence detection with the data value stored in the storage register 2 is performed at every timing. Here, since three low-order bits are effective for the coincidence detection, coincidence detection output CO from the comparator 31 goes to a level '1' when the data value of three low-order bits of the storage register 1 is set at (5).
