  • Patent number: 10029436
    Abstract: Provided are an electrolytic cathode structure that can suppress the degradation of an activated cathode even if a reverse current flows upon the stoppage of operation of an electrolyzer in an electrode structure allowing the distance between the electrode and an electrode current collector to be maintained at an approximately constant value, and an electrolyzer using the same. The electrolytic cathode structure includes a metal elastic cushion member 1 compressed and accommodated between an activated cathode 2 and a cathode current collector 3. At least a surface layer of the cathode current collector 3 consumes a larger oxidation current per unit area than the activated cathode. The electrolyzer is partitioned by an ion exchange membrane into an anode chamber for accommodating an anode and a cathode chamber for accommodating a cathode. The electrolytic cathode structure is used for the cathode.

  • Patent number: 9559748
    Abstract: A transmitter includes a synthesis filter bank to spread a data symbol to a plurality of frequencies by encoding the data symbol on each frequency, apply a common pulse-shaping filter, and apply gains to the frequencies such that a power level of each frequency is less than a noise level of other communication signals within the spectrum. Each frequency is modulated onto a different evenly spaced subcarrier. A demodulator in a receiver converts a radio frequency input to a spread-spectrum signal in a baseband. A matched filter filters the spread-spectrum signal with a common filter having characteristics matched to the synthesis filter bank in the transmitter by filtering each frequency to generate a sequence of narrow pulses. A carrier recovery unit generates control signals responsive to the sequence of narrow pulses suitable for generating a phase-locked loop between the demodulator, the matched filter, and the carrier recovery unit.

  • Patent number: 8864059
    Abstract: A printing device includes a first roller for rotatably retaining a roll body where a medium is rolled, a first motor for rotating the first roller, a second roller installed further to the downstream side of the roll body in the feeding direction of the medium to feed the medium in the feeding direction or in a reverse feeding direction which is opposite to the feeding direction corresponding to the rotating direction, a second motor for rotating the second roller, and a controller which causes the medium to become slack the first roller and the second roller by feeding the medium by a predetermined feeding amount in the reverse feeding direction by the second motor, and then rotates the roll body in a winding-up direction by the first motor so that the slackness decreases to calculate the diameter of the roll body based on the rotation amount of the first roller at that time and the predetermined feeding amount.

  • Patent number: 7967234
    Abstract: The method of preventing over tension to an umbilical wrapped on the spool of an offshore reel when the umbilical is being normally deployed or retrieved or when the umbilical is unexpectedly pulled from the spool on the reel, comprising providing a main disk, mounting the main disk on the spool of the reel with a slip connection which will be automatically controlled, connecting motor power for the reel to the main disk, connecting brakes to the main disk, such that when the diameter of deployment varies the slip connection torque will be automatically adjusted and prevent the umbilical from being subjected to tension higher than the desired amount.

  • Patent number: 6651408
    Abstract: An adjustable force wrapping material brake mechanism and dispenser assembly for an agricultural baler. The assembly includes a wrapping material dispenser roll mount rotatably supporting a wrapping material dispenser roll. A brake-biasing arm is provided having a first end fixedly connected to a first end of a rotatable shaft. A tension arm is connected to the second end of the shaft, and bears a counter roller disposed to roll on a surface of the material dispenser roll. A pivotable monolithic brake lever arm is provided with a brake pad. A single tension spring connects the brake biasing arm and the brake lever arm to bias the brake pad to contact the brake drum with a biasing force, and thereby braking the dispenser roll. As wrapping material is dispensed, the tension arm and brake biasing arm rotate to reduce the biasing force of the spring.

  • Patent number: 6240974
    Abstract: The tension of catch selvage yarns reeling off a yarn supply spool is kept constant by applying a braking force to the supply spool by a disk brake. The brake has a brake disk (12) rotating with the yarn supply spool (1′) and a position variable brake component (20) which is responsive in its instantaneous position to the instantaneous diameter of a yarn supply on the supply spool (1′) as sensed by a yarn follower (8) such as a roller that contacts the yarn on the spool, preferably under a spring bias.

  • Patent number: 6168108
    Abstract: A web tension control and apparatus uses a lightweight dancer and a control system that detects web tension using the dancer position as well as downstream sensors to maintain a relatively constant web tension. The control system also adjusts the braking force to an unwind roll based on the diameter of the roll, allowing for greater web tension control. A two-phase braking system prevents the unwind roll from spilling excess paper into the production line.
