A lithium secondary battery includes a cathode which can be dischargeably charged with lithium ions, an anode made of lithium metal, a lithium alloy or any other anode material which can be releasably doped with lithium ions, and an electrolyte which allows migration of lithium ions between both electrodes. The cathode contains a halogen compound which releases halogen atoms, halogen ions or a reactive halogen-containing substance for reacting with the anode, thereby deactivating the anode to prevent excessive heat generation before oxygen released from the cathode due to a temperature rise reacts with the anode.
摘要:
A lithium secondary battery includes a cathode which can be dischargeably charged with lithium ions, an anode made of lithium metal, a lithium alloy or any other anode material which can be releasably doped with lithium ions, an electrolyte which allows migration of lithium ions between both electrodes, and an endothermic substance which undergoes an endothermic reaction upon a temperature rise of the battery for preventing excessive heat generation. Typically, the endothermic substance is a metal carbonate such as magnesium carbonate, cobalt (II) carbonate, silver carbonate, cadmium carbonate or sodium hydrogencarbonate.

The purpose of the present invention is to provide a gasket material that is capable of preventing corrosion caused by sulfur element, can be used as a seal part for a product that is easily damaged by corrosion, such as an electronic part, and is capable of forming a tight seal under low surface pressure with a material having low rigidity and inadequate reliability such as to have a blowhole, and that can prevent reduction in bolt axial load without producing plastic flow (setting) under pressure. The purpose is achieved by a gasket material in which a foamed rubber layer having a closed cell structure is formed, via an adhesive layer, on at least one side of a metal plate, wherein the foamed rubber layer comprises a carboxyl group-modified nitrile rubber, the expansion ratio of the foamed rubber layer is 2.0 to 3.0, and the foamed rubber layer is crosslinked with an epoxy compound.

A suspension device includes a wheel supporting member configured to rotatably support a wheel. Two links respectively link the wheel supporting member and a vehicle-body side member and are disposed substantially in parallel in a vehicle width direction. At least one projecting portion extends from at least one of the two links towards the other link, and an elastic linking portion links the projecting portion of one of the links to at least one of the other link and the projecting portion of the other link. A toe angle adjusting device is configured to input a force in a direction oriented backward in the vehicle forward-backward direction to the wheel supporting member to adjust a toe-in angle of the wheel.

A disk cartridge that has high durability with respect to a drop impact is provided. The disk cartridge includes: a disk-like recording medium; a cartridge case that rotatably accommodates the disk-like recording medium and is formed with a first opening that exposes a part of the disk-like recording medium; an inner rotor that is rotatably supported inside the cartridge case and includes a main surface portion formed with a second opening corresponding to the first opening; shutter members that are movable between a closing position at which the first opening is closed and an opening position at which the first opening is opened in accordance with a rotation of the inner rotor; and a buffer mechanism that is formed on the main surface portion of the inner rotor and includes rotary shafts that rotatably support the shutter members and elastic support portions that respectively support the rotary shafts and can be elastically deformed with respect to the main surface portion.

A fixing device includes a temperature measuring unit, configured to measure the temperature in regions that extend partially along the outer surface of a heating rotating body, which includes a resistance heating layer, in the circumferential direction and are aligned in the direction of the axis of rotation of the heat rotating body, and a control unit configured to sample temperatures, measured by the temperature measuring unit in each of the regions, over the entire outer surface of the heating rotating body in the circumferential direction by causing the heating rotating body to rotate while supplying a predetermined amount of power to the resistance heating layer, and to determine whether an abnormality has occurred in the resistance heating layer based on the difference between the maximum temperature and the minimum temperature among the sampled temperatures in each region.
摘要:
A disk cartridge includes, between a recordable position and an unrecordable position, a first guide surface that gradually increases an elastic force of an elastic arm of a tab member and a second guide surface that gradually decreases the elastic force of the elastic arm, and a guide wall (guide portion) on which the guide surfaces are formed continuously.

In a storage system provided with a plurality of storage modules, the rated power consumption can be reduced. The storage system is provided with a charge control unit. The charge control unit stops, when detecting that a predetermined number of a plurality of battery modules are during battery charging, the battery charging in the remaining battery modules.
摘要:
In view of the fact that the reproducibility of a finger vein pattern is deteriorated in an image of the finger vein due to external scattered light, displacement, change in the amount of blood flow and the like, a multiple-valued pattern matching method is adopted so that such changes can be dealt with by converting a data map itself into a multiple-valued map.
