Disclosed is a separator in which a porous coating layer is formed of a mixture of inorganic material particles and a binder polymer on the surface of a porous substrate.

The present invention provides a light-emitting element sandwiching a composite layer in which an organic compound and an inorganic compound are mixed between a first electrode and a second electrode, where the composite layer includes a first layer including a first organic compound and a first inorganic compound that exhibits an electron accepting property to the first organic compound (serves as an electron acceptor), a second layer including a second organic compound and a second inorganic compound, and a third layer including a third organic compound and a third inorganic compound that exhibits an electron donating property to the third organic compound (serves as an electron acceptor).

Disclosed is a positive electrode plate (2) which comprises: a double side coated part (14) in which an active material layer (13) and a porous protective film (28) are formed on the both surfaces of a collector core material (12); a core material exposed part (18); and a single side coated part (17) which is positioned between the double side coated part (14) and the core material exposed part (18) and in which the active material layer (13) and the porous protective film (28) are formed on one surface of the collector core material (12). The double side coated part (14) is provided with a plurality of grooves (10), but the single side coated part (17) is not provided with a groove (10). The grooves (10) are so formed as to extend from the surface of the porous protective film (28) to the surface of the active material layer (13). A collector lead (20) of the positive electrode is connected to the core material exposed part (18), and the positive electrode plate (2) is rolled up in such a manner that the core material exposed part (18) makes the roll end.

A primary objective of the present invention is to provide a solid cell with which it is possible to alleviate short-circuits between electrodes. The present invention is a solid cell, comprising a first electrode layer, a second electrode layer, and a solid electrolyte layer which is positioned between the first electrode layer and the second electrode layer. A first insulation layer is positioned upon the exterior circumference of the first electrode layer. The size of the stack face of the first electrode layer, taking the stack direction of the first electrode layer, the solid electrolyte layer, and the second electrode layer as the direction of the normal thereof, is smaller than the size of the stack face of the solid electrolyte layer. When viewed from the stack direction, the outer edge of the solid electrolyte layer is located upon the exterior circumference of the first electrode layer, and the outer edge of the first insulation layer is located on the exterior circumference of the solid electrolyte layer. The first electrode layer, the first insulation layer, and the solid electrolyte layer are positioned such that the outer edge of the first insulation layer and the end parts of the solid electrolyte layer make contact.

An end plate (16) is made of a magnetic material, and holds an axis-direction end surface of a rotor core (14) in which a permanent magnet (20) is buried. The end plate includes: a protruded portion (44) constructed so as to be caused to pressingly contact the axis-direction end surface of the rotor core (14) when mounted in the rotor (10); and a depressed portion (46) constructed so as not to contact the axis-direction end surface (17). The protruded portion (44) is formed so as to contact only one of a d-axis magnetic path region and a q-axis magnetic path region that are formed by the permanent magnet (20) within the rotor core (14).

The invention provides a waterproof connector and a manufacturing method thereof. A waterproof connector (10) has: at least one conductive contact (12); a metal shell (16) interior of which the contact is disposed; and a housing (32) made of an insulating resin material such that the housing fixes the contact and the shell to form an integral structure, the shell has an insertion port (21) into which a counterpart connector is inserted on one side, and the housing is formed such that the shell is exposed at the outer circumference of and at the vicinity of the insertion port over a predetermined width in the length direction of the shell to form an outer circumferential exposure portion (24), and the outer circumferential exposure portion of the shell is disposed with a waterproof portion (49) made of an elastic material.

A charge-transporting thin film having excellent flatness can be obtained with good repeatability using the charge-transporting varnish of the present invention, which contains: a charge transportation substance comprising a charge-transporting monomer or a charge-transporting oligomer or polymer having a number-average molecular weight of 200-50,000, or a charge transporting material comprising the charge transportation substance and a dopant substance; and a mixed solvent including at least one type of good solvent and at least one type of poor solvent; the absolute value of the boiling point difference DeltaT°C of the good solvent and the poor solvent satisfying the relation |DeltaT| < 20°C; the viscosity at 25°C being 7.5 mPa.s or less; the surface tension at 23°C being 30.0-40.0 mN / m; and the charge-transporting material being dissolved or uniformly dispersed in the mixed solvent.
