A drive device includes: a rotor and a stator; a case housing the rotor and the stator; a brake rotor that is arranged on the outside of the case and rotates in conjunction with the rotation of the rotor; a brake caliper that stops the rotation of the brake rotor by coming in contact with the brake rotor; and a ventilation membrane that is attached to the case, stops fluid or solids from penetrating inside the case from outside the case and also has formed therein multiple pores that permit gas to flow between inside and outside. The case has an output part that supports the rotor and a stator holding part that supports the stator. The ventilation membrane is attached to the stator holding part.

Drive device and ventilation member

A vehicle lampis provided with: a ventilating unitthat is provided with a first openingof a closed case, prevents entry of liquids and solids to an inside space S within the case, and allows circulation of air between the inside space S and an outside space of the vehicle lamp; and a dehumidifying unitthat is provided in a second openingof the casedifferent in position from the first openingand has an electrolysis dehumidifying element for discharging water vapor in the inside space S to the outside of the vehicle lampby electrolysis. Thus, a dehumidifying device and a lamp that can rapidly discharge water vapor that has entered the inside of a housing to the outside of the housing can be provided.

Dehumidifying device and lamp

The present invention relates to an organic electroluminescent device comprising a substrate, an organic electroluminescent element, and a photocatalyst layer, wherein the organic electroluminescent element includes: a first conductive layer provided on the substrate; an organic electroluminescent layer provided on the first conductive layer; and a second conductive layer provided on the organic electroluminescent layer, wherein the photocatalyst layer covers all or part of a light-emitting region of the organic electroluminescent element, and contains a photocatalyst and a co-catalyst, and wherein an absolute value of the difference (|R1&#x2212;R2|) between the refractive index (R1) of the photocatalyst and the refractive index (R2) of the co-catalyst at a wavelength of 589 nm is 0 to 0.35.

Organic electroluminescent device having a photocatalyst layer

A spiral wound type membrane element is formed by superposing gas-liquid contact membranes on both surfaces of a first fluid passage forming member, superposing a second fluid passage forming member on the surface of one of the gas-liquid contact membranes and spirally winding the gas-liquid contact membranes around a second fluid supply pipe along with the first fluid passage forming member and the second fluid passage forming member. A side portion on the inner peripheral side and a side portion on the outer peripheral side of a first fluid passage formed by the first fluid passage forming member between the gas-liquid contact membranes are sealed. Both end portions of a second fluid passage formed by the second fluid passage forming member between the gas-liquid contact membranes are sealed. The spiral wound type membrane element is stored inside a cylindrical container. The gas-liquid contact membranes are formed by PTFE (polytetrafluoroethylene) porous membranes having hydrophobicity. First fluid is supplied from a first fluid inlet of the cylindrical container, passes through the first fluid passage of the spiral wound type membrane element and is taken outward from a first fluid outlet of the cylindrical container. Second fluid is supplied into the second fluid supply pipe from a second fluid inlet of the cylindrical container, passes through the second fluid passage of the spiral wound type membrane element and is taken outward from a second fluid outlet of the cylindrical container.
