Abstract:
In order to manufacture a lithium secondary battery having excellent performances in safety under overcharge condition, cycle property, electric capacity, and storage endurance, 0.1 wt. % to 10 wt. of a tert-alkylbenzene compound is favorably incorporated into a non-aqueous electrolytic solution comprising a non-aqueous solvent and an electrolyte, preferably in combination with 0.1 wt. % to 1.5 wt. % of a biphenyl compound.
Abstract:
A composition for stabilizing chlorine dioxide maintains a chlorine dioxide concentration nearly constant in the agent containing chlorine dioxide dissolved therein even when chlorine dioxide is continuously released as gas from agent, and includes a chlorite and a pH adjuster. The pH adjuster is an acid or a salt thereof having a buffering property whose pH is 2.5 to 6.8 as a 5% aqueous solution at 25° C.
Abstract:
An image-forming device includes a main casing, a drum unit, an image-forming unit, and a transfer unit. The drum unit is detachable from the main casing and includes a photosensitive drum having a rotational axis extending in an axis direction. The drum unit is formed with a plurality of symbols juxtaposed along the axis direction. The image-forming unit forms an image on the photosensitive drum in an image-forming mode. The transfer unit transfers the first developer image onto the photosensitive drum onto a sheet. The image-forming unit forms a first developer image on the photosensitive drum in a maintenance mode. The first developer image transferred onto the sheet divides the sheet into a plurality of regions along the axis direction, the plurality of regions corresponding to the plurality of symbols, respectively.
Abstract:
A first rotary body is configured to rotate by a drive force input from an external source and has a first outer peripheral surface. A second rotary body is configured to rotate by following a rotation of the first rotary body through the friction generated between the first outer peripheral surface and the second outer peripheral surface. A first gear is configured to rotate together with the first rotary body. A second gear is configured to rotate together with the second rotary body and is directory engaged with the first gear. The first gear had a first pitch circle and the second gear has a second pitch circle. A radius of the first pitch circle is smaller than the radius of the first rotary body, and a radius of the second pitch circle is larger than the radius of the second rotary body.
Abstract:
A non-aqueous electrolytic solution is advantageously used in preparation of a lithium secondary battery excellent in cycle characteristics. In the non-aqueous electrolytic solution for a lithium secondary battery, an electrolyte salt is dissolved in a non-aqueous solvent. The non-aqueous electrolytic solution further contains a vinylene carbonate compound in an amount of 0.01 to 10 wt. %, and an alkyne compound in an amount of 0.01 to 10 wt. %.
Abstract:
According to one embodiment, a television apparatus includes a housing and a cover. The housing is provided with an opening for opening a housing portion to house an electronic component. The cover is attached to the housing. The cover is configured to cover the opening, and includes a honeycomb-like rib on the rear face.
Abstract:
A photosensitive unit includes: a photosensitive member that carries a developer image on a surface thereof; a primary roller, which contacts the surface of the photosensitive member, and which captures a foreign substance on the surface of the photosensitive member; a pair of primary bearing members that rotatably support axial end portions of the primary roller; a pair of pressing members that press the pair of primary bearing members toward the photosensitive member; and a pair of guide members that guide the pair of primary bearing members in a pressing direction in which the pair of pressing members press the pair of primary bearing members.
Abstract:
A process cartridge and an image forming apparatus are provided. The process cartridge is detachably mountable in an apparatus body of the image forming apparatus, and includes a plurality of photosensitive drums, a first outer side plate which is provided on one side of the photosensitive drums in an axial direction of the photosensitive drum, a second outer side plate which is provided on the other side of the photosensitive drums in the axial direction, and opposes the first outer side plate with the photosensitive drums interposed therebetween, and a plurality of input parts which are provided on ends of the photosensitive drums at the one side, respectively. An end face of each of the input parts being provided inward with respect to the outer surface of the first outer side plate.
Abstract:
An image forming apparatus is provided. The image forming apparatus includes a single drive source, at least four photosensitive drums, a plurality of drum drive gears which are provided to correspond to the photosensitive drums, and a plurality of intermediate gears which are interposed between the drive source and each of the drum drive gears. A number of the intermediate gears provided for each of the photosensitive drums is same.
Abstract:
The sudden generation of heat being frequently caused in the case of the overcharge of a lithium secondary cell which have a positive electrode comprising a composite metal oxide of lithium and cobalt or a composite metal oxide of lithium and nickel, a negative electrode comprising metallic lithium, a lithium alloy or a material capable of occluding and releasing lithium, and a nonaqueous electrolyte solution comprising a nonaqueous solvent and an electrolyte dissolved therein can be efficiently prevented by the addition, to the nonaqueous electrolyte solution, of an organic compound which, when the lithium secondary cell is overcharged, decomposes into a decomposition product capable of dissolving out the cobalt or nickel contained in the positive electrode and depositing it ion the negative electrode (for example, a tert-alkylbenzene derivative).
