Abstract: A resin molded article has an internal space. The resin molded article includes: a ventilation passage defined to allow the internal space to communicate with an outside of the resin molded article. The ventilation passage includes: a first ventilation passage extending from the internal space in a predetermined direction so as to include a bottom portion; and a second ventilation passage extending from the outside in a direction intersecting the predetermined direction. The first ventilation passage and the second ventilation passage communicate with each other by allowing the bottom portion to communicate with the bifurcated portions provided at an end portion of the second ventilation passage. A portion where the first ventilation passage and the second ventilation passage communicate with each other is narrowest in the ventilation passage.

Abstract: In an accident pattern determination apparatus including a storage storing attributes assigned to respective ones of a plurality of predefined traffic situations, an acquirer acquires, for each of vehicle-related accident cases, an accident pattern that is a combination of traffic situations in the accident case, from the plurality of predefined traffic situations. A determiner determines, for each accident pattern acquired by the acquirer, whether the accident pattern is an accident pattern of high accident risk or an accident pattern of low accident risk for specific vehicles, based on the accident patterns acquired for the respective accident cases and the attributes assigned to respective ones of the plurality of predefined traffic situations.

Abstract: A glass panel unit includes: a first substrate including a first glass panel; a second substrate including a second glass panel; and a frame-shaped sealing portion that is hermetically bonded to the first substrate and the second substrate. The sealing portion creates an evacuated space between the first substrate and the second substrate. When viewed from a region where the second substrate is positioned with respect to the first substrate, the first substrate includes a part arranged to stick out of an edge of the second substrate. The part includes a mounting portion used to mount the glass panel unit onto a vehicle.

Abstract: A work in progress includes: a pair of glass substrates arranged to face each other; a peripheral wall having a frame shape and disposed between the pair of glass substrates; a boundary wall; and an evacuation port. The boundary wall hermetically separates an internal space, surrounded with the pair of glass substrates and the peripheral wall, into an evacuation space, a buffer space, and a ventilation space. The evacuation port connects the ventilation space to an external environment. The evacuation space and the buffer space have a lower internal pressure than the ventilation space. A predetermined part, including the evacuation space but excluding parts covering the buffer space and the ventilation space, of the work in progress, forms the glass panel unit.

Abstract: It is an object of the present invention to close a slit as easily as possible while suppressing positional displacement of both end edge portions flanking the slit. A corrugated tube includes a corrugated tube body portion formed in a tubular shape in which annular projecting portions and annular recessed portions are alternately formed in a longitudinal direction and a slit is formed in a longitudinal direction; a plurality of first extended pieces provided on one side of both side edge portions flanking the slit in the corrugated tube body portion; and a plurality of second extended pieces provided on the other side of both the side edge portions. The slit is closed in a state where the plurality of the first extended pieces and the plurality of the second extended pieces are disposed on an inner circumferential side of the corrugated tube body portion at different positions.

Abstract: In a solder paste which is a mixture of a flux and low melting point metal particles, low melting point metal fine particles manufactured by a conventional method or apparatus therefor include particles having widely varying particle diameters. Accordingly, the solder paste could not completely fill the minute holes in a mask for application to minute solder portions by printing, or mask removability was poor. According to the present invention, a mixture of a heat resistant continuous phase liquid and coarse metal particles in molten state is passed through a porous membrane to form the coarse low melting point metal particles into fine particles with a predetermined diameter. An apparatus according to the present invention comprise a porous membrane between a heating and dispersing mechanism and a cooling mechanism, and a pressure vessel connected to the heating and dispersing mechanism for applying a high pressure to the heating and dispersing mechanism.

Abstract: A method of making metallic iron in which a compact, containing iron oxide such as iron ore or the like and a carbonaceous reductant such as coal or the like, is used as material, and the iron oxide is reduced through the application of heat, thereby making metallic iron. In the course of this reduction, a shell composed of metallic iron is generated and grown on the surface of the compact, and slag aggregates inside the shell. This reduction continues until substantially no iron oxide is present within the metallic iron shell. Subsequently, heating is further performed to melt the metallic iron and slag. Molten metallic iron and molten slag are separated one from the other, thereby obtaining metallic iron with a relatively high metallization ratio.
