摘要:
A sample tube of a sampling valve is moved up and down by a cylinder. When the sample tube is moved downward, a sample inlet opposes a stored sample, and the sample can be extracted. When the sample tube is moved upward, the sample inlet opposes a cleaning liquid path. Thus, cleaning liquid is fed into the cleaning liquid path from a cleaning liquid supply port of a cleaning pipe. The cleaning liquid flows within the sample tube from the sample inlet, and flows out from a sample discharge port. Thus, an entire interior of the sample tube can be cleaned. In a sample extracting device using the sampling valve, a state in which no air or impurities are mixed in the sample can always be maintained, such that stable extraction can be carried out.

摘要:
A lower wall partially defining a fuel storing chamber of a fuel tank curves upward in accordance a decrease in an amount of fuel stored in the fuel storing chamber. The volume of a gaseous space in the fuel storing chamber is reduced, in comparison with a fuel tank in which a lower wall does not deform, by an amount corresponding to a reduction of the volume of the fuel storing chamber achieved by the curvature of the lower wall. An amount of fuel not discharged from the fuel storing chamber via a fuel passage but remaining near a peripheral end portion of the lower wall of the fuel storing chamber due to the upward curvature of the lower wall is discharged via a residual fuel discharging pipe, so that the residual fuel amount of the fuel storing chamber is minimized.

Disclosed is a diode device in which two electrodes of regions forming both terminals are provided on the same face, thereby enabling the device to be connected to a circuit substrate by face-down bonding. Since a region is located within the semiconductor base, an electrode cannot be connected at the top face thereof; to overcome this, a groove is provided extending in a perpendicular direction from the top face of the semiconductor base to the region, and an electrode is provided in the groove. Then, the electrode in the groove is exposed at the top face, enabling the electrodes of both regions to be connected at the top face.

A developing device used in an electrophotographic apparatus has seal members fixedly disposed between both end portions of a developing roller and those portions of inner walls of a device casing which correspond to both end portions of the developing roller. The seal members are made of a material which can be charged by friction with the developing roller to have the same polarity as charged toner. The toner is blocked by the seal members and presented from entering end portions of the developing roller.

A novel gamma retinoic acid receptor is disclosed. The novel receptor is encoded for by cDNA carried on plasmid pGEM-hRAR.gamma., which has been deposited with the American Type Culture Collection for patent purposes. Chimeric receptor proteins are also disclosed. The chimera contain at least one functional domain from the new gamma retinoic acid receptor.

A projectable or push-out type writing instrument cartridge, such as a projectable cartridge for a ball point pen, has a filler impregnated with an aqueous ink, a writing point at its one end, a device for feeding the ink to the writing point, and an end plug mounted in the other end of the cartridge. The plug has an air passage which satisfies a predetermined condition. Preferably, the end plug consists of an inner rod and an outer tube which receives the inner rod in such a manner that the air passage is formed between the rod and the tube. The cartridge is secured in the casing of the instrument, and is projectable to a writing position.
摘要:
A plurality of analog memory devices alternately store successive one-line segments of facsimile signals. During the write-in period of one memory, the signals of one-line segments are stored while the immediately preceding one-line segment is read out of the other memory and processed to make an amplitude comparison for each picture element. The amplitude comparison is translated into a width of an output pulse for each picture element, which width also reflects the time duration of the facsimile recording paper. Thus, a picture is reproduced with a gradation of shade values.

The efficiency of work for constructing the roof, the external walls and the like of a house will be greatly improved if the architectural material is standardized and designed to minimize the processing which must be made at the site. To this end, there is provided a specific profile of an architectural panel material, i.e. a substantially inverted T-shaped profile mainly consisting of a main body section having an inclined area, and an overlapping head section having an overlapping area continuous with and projecting toward the upper side from the inclined area. Remarkable effects, in addition to above stated advantages, are derived from this profile, such as preventing infiltration of rainwater into the back side of the panel, improved mechanical strength, and an attractive three-dimensional appearance of the finished roof and external wall.
摘要:
The invention provides a heat-resistant composite comprising a noncombustible porous core material (e.g., a calcined mineral such as perlite, etc.) which has been impregnated or coated with an inorganic filler material (e.g., sodium metaborate, sodium meta silicate, sodium metaphosphate, etc.) capable of foaming spontaneously when heated at an elevated temperature. The composite may be incorporated in a molded synthetic resin (e.g., polyurethane) to obtain a flame and heat-resistant molded article in the form of a panel useful as a building material, which, in turn, may be sandwiched between a facing material (e.g., a steel plate, plywood, etc.) and a backing material (e.g., aluminum foil, asbestos paper, etc.) to form a heat-resistant structure which is also useful as a building material. The composite may also be formed by mixing and pelletizing at least one organic filler material with a clay (e.g., kaolin, bentonite, etc.) and incorporating this composite into a synthetic resin panel to obtain a flame and heat-resistant panel also suitable as a building material.
