  • Patent number: 11764408
    Abstract: A battery includes a positive electrode having a first strip shape and a positive electrode lead, and a negative electrode having a second strip shape and a negative electrode lead. First ends of the positive electrode and the negative electrode in a longitudinal direction are on an inner peripheral side, and second ends of the positive electrode and the negative electrode in the longitudinal direction are on an outer peripheral side. The positive electrode lead and the negative electrode lead are extended out from a first end side in a width direction of the positive electrode and the negative electrode, and a first thickness of the positive electrode on the first end side is thinner than a second thickness of the positive electrode on a second end side in the width direction.

  • Patent number: 10873109
    Abstract: A secondary battery includes a cathode terminal; an anode terminal; a wound electrode body; and a step reducing member. The step reducing member is attached to one or both of a first cathode wound portion and a first anode wound portion in one or more of a first region, a second region and a third region. The first region is in a major axis direction outside the cathode terminal in a wound direction of a cathode, and the second region is in the major axis direction outside the anode terminal in the wound direction of an anode and the third region between the cathode terminal and the anode terminal.

  • Publication number: 20030036285
    Abstract: Methods for fabricating semiconductor devices are described, including methods which improve an etching selection ratio of a film to be etched against metal silicide, Si, and photoresist. One method for fabricating a semiconductor device includes the steps of forming Ti silicide films 9a-9c on the gate electrode 3 and the diffusion layers 6 and 7 of source/drain regions, forming an interlayer dielectric film 10 on the Ti silicide films, and dry-etching the interlayer dielectric film to form in the interlayer dielectric film 10 a contact hole 10a located above the gate electrode, and contact holes 10b and 10c located above the diffusion layers of the source/drain regions, wherein etching gas used for the dry-etching is gas including at least fluorocarbon gas and one of O2 gas and O3 gas, and the temperature of the semiconductor substrate is 30° C. or lower when the dry-etching is conducted.

  • Patent number: 6365548
    Abstract: The present invention is a treatment method for preserving cut flowers, which has a dehydration process for removing the tissue water of cut flowers using a solvent, and a permeation process for letting polyethylene glycol permeate after dehydration, to substitute the solvent by polyethylene glycol, characterized in that the dehydration process is effected while the cut flowers are fixed in a container having a proper amount of a molecular sieve spread over its bottom and filled with a solvent having a specific gravity smaller than that of water, wherein the specific gravity of the solvent is measured to monitor the change of the solvent in dehydratability, and the time when the specific gravity suddenly rises is detected as the time for exchanging the molecular sieve for a new one, to restore the dehydratability of the solvent, thereby allowing the solvent to be used continuously and allowing the dehydration process to be continued without waste of time.

  • Patent number: 4793298
    Abstract: A ventilator for an ignition distributor used with an automobile comprises an air intake passage for sucking air from the outside of the distributor and an air exhaust passage for exhausting the air to the outside of the distributor. Each passage has one end opening in the upper surface of the bottom of the distributor, and the other end opening in the outer surface of the distributor. These openings of each passage are connected to each other through a passage bent at an obtuse angle or a passage having an intermediate bent passage portion formed in a circular arc shape.
