Filed: 1991-07-26
Abstract: PURPOSE:To integrate the optical circuit to a higher scale so as to have more functions and to improve productivity by having a substrate removed part worked from the rear surface side in the part below the optical waveguide of a plane substrate. CONSTITUTION:The optical circuit 20 has the optical waveguide 3 produced on the plane substrate 2 consisting of silicon and has a thin-film heater 7 consisting of a metal on this optical waveguide 3. The optical waveguide 3 is produced from quartz glass as a blank material and consists of a core part 4 where light propagates and a clad part 5 which is formed around this core part 4 and has the refractive index lower than the refractive index of the core part 4. The plane substrate 2 consisting of the silicon is completely removed by cutting and etching from the rear surface side right under the part of the optical waveguide 3 where the thin-film heater 7 is provided, by which the substrate removed part 6 is locally formed. The local functioning on the substrata 2 is obtd. by utilizing this substrate removed part 6.

IPC: H04N5/44
Filed: 1985-08-27
Abstract: PURPOSE:To avoid an influence due to the fluctuation or the like of a power source by connecting positive and negative side comparison circuits for respectively outputting at the time of above a positive set voltage and at the time of below a negative set voltage to the output side of an amplifier circuit for amplifying positive and negative signals centering 0V through a smoothing circuit. CONSTITUTION:When the voltage of an S-shaped curve is inputted to an input terminal 1, it is smoothed by a smoothing circuit 8 and amplifier in either direction of a positive and a negative centering 0V in a prestage amplifier circuit 2. This voltage is further amplifier by a post stage amplifier circuit 3, and thereafter inputted to positive side and negative side comparison circuits 4, 5. When its input voltage is situated within the range of a set voltage, there is no output in both of output terminals 12, 16 and a local oscillating circuit is not controlled. When the voltage exceeds the set voltage, there is an output from the positive side comparison circuit 4 and when the voltage is smaller than the set voltage, there is an output from the negative side comparison circuit 5, which respectively controls a local oscillating frequency so as to return an intermediate frequency to a center. Thereby, even if a signal is minute, the width of the frequency is wide, it is effectively detected and the influence of the fluctuation of a power source is reduced.

Title: Device and method for phase detection for use with digital phase locked loop or other phase sensitive device
Inventor: REBUAIN SUTEIIBUN ENU
IPC: H03K5/13
Filed: 1991-07-02
Abstract: PURPOSE: To adjust loop bandwidth and phase by sampling a received data signal with an output signal of a phase-locked loop and generating a phase proceeding signal or a phase delay signal based on the comparison between samples. CONSTITUTION: A phase comparator 18 gives a reference clock signal or an output signal that shows the relative phase of a received data signal f1 , and a phase-locked loop output signal f0 is used to sample the signal f1 . FFs 137 and 139 compare the signal f1 with a DPLL output signal, and when the signal f1 precedes an output signal of the divider 16, the FF 137 sets a signal G to H. Because the FF is directly locked by the f0 , the signal G is set to H in a rise section of f transition. The FF 139 has a signal L set to H each time the f0 transition, and because of 1/2 delay that is generated by the F139, Sfo is set to H after 1/2 cycle passes after the f0 is set to H. In this way, phase correction is performed about positive transition of the signal L.

Title: Magnetic tape device
Inventor: KOMIYAMA CHISATO
IPC: G11B15/05
Filed: 1981-11-24
Abstract: PURPOSE:To eliminate the necessity for the resetting of a magnetic tape that is done manually, by starting the counting of the traveling length signals after detecting an end marker of the magnetic tape and stopping a tape traveling system when the above-mentioned counting reaches the prescribed value. CONSTITUTION:When a detecting circuit 4 detects an end marker of a traveling magnetic tape, the numerical value showing a certain distance of the tape from the end marker is set. At the same time, a counter 2 starts the down-counting. When this count value is set at 0, the stop signal is applied to a magnetic tape traveling system 1 from the counter 2 to stop the traveling of the tape. Therefore the magnetic tape of the file reel side is completely taken up to a machine reel even through the data block is not recognized due to a tape defect or a trouble of a hardware, etc. This eliminate the manual resetting of the magnetic tape.
