摘要:
In a lithium-ion secondary battery using a positive-electrode active material that includes a lithium-manganese-based oxide which includes a lithium (Li) element and a tetravalent manganese (Mn) element and whose crystal structure belongs to a layered rock-salt structure, adding a compound being selected from the group consisting of Compounds (a) through (i) into the electrolytic solution leads to the following: degradations due to oxidation-reduction decompositions of the electrolytic solution, and so on, are inhibited; and not only the shelf or storage capacity and recovered capacity upgrade in the case of being stored at high temperatures, but also the rise of internal resistance is inhibited.

The invention provides a surgical device for endoscopic surgery having the function of temporarily storing liquid (a first function), the function of keeping a physical space for surgery and a sufficient endoscopic field (a second function), and the function of protecting organs (a third function), and an insertion device for inserting the surgical device into a body.[Solving Means] The surgical device for endoscopic surgery is an inter-organ spacer (10) including liquid holding means (1) formed of a porous soft material having the ability to temporarily store liquid and the ability to retain its shape. The insertion device for inserting the inter-organ spacer into a body includes a tubular holder capable of holding the inter-organ spacer for endoscopic surgery.

Proposed is a novel soluble trauma-healing and hemostatic cellulose fiber capable of absorbing and readily dissolving hemorrhaging trauma loci when applied thereto and of promoting the hemostatic action of blood platelets and fibrin and cell adhesion to the trauma site. The coagulation protein-containing soluble trauma-healing and hemostatic cellulose fiber is produced in that after treatment of a natural or regenerated cellulose fiber with an aqueous sodium hydroxide solution, said fiber is carboxymethylated by reaction with a monochloro acetic acid solution for a given time (hours) in such a manner that the degree of partial substitution of the glucose units constituting the cellulose molecule (etherification degree) is 0.5-less than 1.0% and that, furthermore, the coagulation proteins fibrinogen, thrombin, and coagulation factor XIII are imparted by surface application or chemical bonding.
摘要:
A light-emitting device that uses an organic electroluminescent element, wherein the application of reverse voltage is achieved with a simple structure, is disclosed. The light-emitting device may include a power source, an organic electroluminescent element, and a capacitor. When the light-emitting device is on, the power source may be used to apply forward voltage to the organic electroluminescent element and charge the capacitor. When the light-emitting device is off, the capacitor may be used to apply reverse voltage to the organic electroluminescent element, without using the power source.
