Title: Optical transmission system
Inventor: TAMURA YUJI
IPC: H04B10/516
Filed: 1994-06-21
Abstract: PURPOSE:To transmit a master signal and a monitor information signal without the use of the signal multiplex system and the wavelength multiplex system by allowing a filter section to pass only a prescribed wavelength component including a main signal optical wavelength among spontaneously emitted light generated in an optical amplifier section, modulating the passed wavelength component and transmitting the modulated signal to an optical transmission line. CONSTITUTION:At master a main signal is subject to electric optic conversion in an optical conversion section 1, a main signal light (a) is given to an optical amplifier section 2, in which the signal light is amplified at a gain to compensate a transmission loss up to an optical repeater of a next stage. The amplified main signal light (b) passes through a modulation display section 3 and is sent to a transmission optical fiber. A monitor information signal is given to a filter drive circuit 32 of the modulation section 3, in which the transmitted wavelength is made varied corresponding to the monitor information signal and then wavelength modulation is applied to the light. That is, a wavelength variable band pass filter 31 has a transmission wavelength wider by a proper value than that of the main signal lights (a), (b) and varies the wavelength by a prescribed wavelength around the wavelength of the main signal light and modulated lights (c), (d) having a prescribed width of spectrum in which part of the spontaneously emitted light is added to the main signal light are obtained.

Title: Recording and reproducing device for digital information
Inventor: KANIWA KOUJI
IPC: G11B5/09
Filed: 1994-06-21
Abstract: PURPOSE:To enable a long duration recording by converting the transmission information having a low transfer rate into a signal form which is suitable for a recording, time axis converting the information having a high transfer rate and conducting a high density recording. CONSTITUTION:Transmission information signals are converted into a signal form which is suitable for a digital signal processing through an input terminal 1 and a modem 5 and inputted to an encoder 7 from a switch 6. The encoder 7 converts the information signals into information data having a transfer rate in which a prescribed time is made into one unit and EEC data and stores them in a memory 8. On the other hand, the encoder 7 transmits the information data, to which ID and EEC data are added, to a memory 10. A control circuit 11 controls the memory 10, reads the data at the transfer rate and supplies the information to a demodulation circuit 12. The circuit 12 demodulates the inputted information and transmits the information to a P/S converting circuit 13. The circuit 13 converts the information into a serial data column and outputs it to a recording amplifier 14. The serial recording data are amplified and recorded on a magnetic tape 15 by magnetic heads 16A or 16B under the control of a drum control circuit 20.

Title: Negative electrode plate for alkaline battery
Inventor: YOSHIMURA MASAYUKI
IPC: H01M4/62
Filed: 1984-07-03
Abstract: PURPOSE:To prevent the fall off of the active material in the process of battery assembly retaining the advantages of the paste type negative electrode, so as to improve its mechanical strength, by using aqueous nylon as the binder of a non-sintered type negative electrode. CONSTITUTION:In the manufacturing process of a paste type Cd negative electrode wherein aqueous nylon is used as single or at least one of plural binder materials, aqueous nylon helps to keep the mechanical strength of the electrode before entering the formation process, whereas it dissolves out into the electrolytic liquid during the formation process. But at the same time, the network of metallic Cd generated in the electrode plate during the same process helps to maintain the mechanical strength thereafter. When the manufacturing does not involve the formation process, aqueous nylon keeps the mechanical strength till the battery assembly is completed, and after that, the strength is maintained as a result of pressing between the electrode plates themselves. Regarding the capacity of the electrode plate, since aqueous nylon finally dissolves out, the active material utilization rate, charge-discharge capacity at high rate, and gas absorption are improved as a result of the increase of the contact area of the active material and the electrolytic liquid, and also due to increase of the porosity.

Title: Chrominance signal processor
Inventor: UCHIYAMA SHINICHI
IPC: H04N9/83
Filed: 1986-06-13
Abstract: PURPOSE:To attain a balanced control against the frequency flcutuation of a VCO in up and down, by setting a deadband from a center frequency keeping balance in up and down, even in both an NTSC and a PAL modes. CONSTITUTION:A frequency divider 6 always performs 1/3 frequency division regardless the NTSC, or the PAL modes. Out of three pulses having phases different by every 120 deg., F1, F2, and G1, of the frequency divider 6, the pulses of the F1 and the G1 are outputted, and at a switch circuit 7, the pulse of the G1 is selected at an NTSC time, and the pulse of F1 is selected at PAL time, and they are counted in a counter 8. In a decoded value at the NTSC time of a frequency detection circuit 9, the maximum frequency is set as about 320.125fH, and the minimum frequency as about 319.625fH against the minimum number of clocks to be the deadband at the NTSC time. Since it is possible to set the deadband balanced in up and down from the center frequency, the function of the frequency detector can be balanced against the frequency fluctuation of the VCO in up and down.

IPC: G01D13/22
Filed: 1986-06-17
Abstract: PURPOSE:To quickly reverse instrument indication value into zero by constituting a counter, changeover circuit, latch counter, inverter, etc. CONSTITUTION:Every time a clock pulse C is supplied, a car speed pulse (b) is counted by a counter 3 and the car speed signal resulting from the counter is latched on a latch counter 7. If a ignition switch 31 is turned off, the voltage of connection point of resistances 35, 37 used for potential divider becomes zero, so that the output of an inverter 9 turns to a high level from a low level and the changeover circuit 5 supplies a loose/tense pulse (d) to the counter 7. At the same time, since the counter 7 also functions as a down counter, the car speed signal being latched being count down by the pulse (d) through the circuit 5, then reducing car speed signal is supplied to coils 17, 18 through ROMs 11, 21 for sine wave and a cosine wave, pulse width modulation circuit 13, 23 and driver parts 15, 25. The pulse (d) is made to be accelerated gradually, therefore the meter reverses to zero with acceleration in a short time.

Next, while both ends of the branched straight pipe SP' is being supported to the receiving means 2, 2 of a press- bending device B 1 , a push-down roll 3 is lowered to hot-bent the straight pipe SP' to a required bending radius. At this time, the receiving means 2, 2 turn around the respective fulcrum axes along with the descending of the roll 3. The thus formed branched bent pipe BP' is set as it is or after reheating, to a press-bending device B 2 , by which it is further bent to a required bending radius. Next, both ends of the bent pipe BP' are cut in the positions (a), (b) and the blank branch pipe T' is cut in the position C. The pipe is then put into split dies DI 2 , by which the reduction of the outside and inside diameters thereof and the sizing of the outside diameter are accomplished.
