A pipet device (A) includes a pipet nozzle (1) formed with an internal passage (10) and a hollow pipet tip (4) removably attached to the nozzle (1). The tip (4) is movable between a normal fixed position and a completely detached position relative to the nozzle (1). The nozzle (1) is formed with an external-air intake groove (16). The intake groove (16) is closed by the tip (4) when the tip (4) is at the normal fixed position. The intake groove (16) is exposed from the tip (4) when the tip (4) is moved from the normal fixed position toward the completely detached position.

A method of fabricating a solid-state imaging device is provided, which enables the formation of an anti-reflection film by oxidizing a surface of a metallic light-shield film without adding additional steps, even though the metallic light-shield film is composed of not only refractory metal silicide but also metals, including tungsten and molybdenum. The method comprises the steps of forming a metallic light-shield film on a light receiving sensor and a transfer electrode formed on a surface layer of a wafer, forming an opening on the metallic light-shield film on the light receiving sensor by etching, forming an interlayer film, and shaping the interlayer film into a lens shape by heat treatment. An atmosphere of either one or both of oxygen gas and ozone gas is prepared in a chamber for forming the interlayer film, and a surface of the metallic light-shield-film is oxidized before the interlayer film is formed.

A cable connector includes a plug for connecting a coaxial cable to an electronic device such as a television or video cassette recorder. The plug includes a sleeve that connects with a first grounding terminal of a receptacle. An outer diameter of the sleeve is dimensioned to provide a good unstressed interference fit with the first grounding terminal. The sleeve has slits in a portion to permit elastic deformation when connecting with a second grounding terminal having an inner diameter less than that of the first grounding terminal. These slits permit the sleeve to compress sufficiently to form an interference fit inside the second grounding terminal. When both the first grounding terminal of the receptacle and the sleeve of the plug are dimensioned for the PAL format, and the second grounding terminal is dimensioned for the SECAM format, the plug fits either grounding terminal.
摘要:
A fuel pump apparatus having two-stage pump sections and a vapor discharge port. A first impeller of a first stage pump section is attached to a vertically lower surface of a second impeller of a second stage pump section, the second impeller having a larger diameter than the first impeller. A vapor discharge port is formed in the second impeller at a radially inward portion thereof to open to a radially inwardly portion of a first pump passage. Fuel vapor is separated from liquid fuel at the first stage pump section and the liquid fuel is pressurized at the second stage pump section.

A pump apparatus of a regenerative type having a vapor discharge port for avoiding a vapor lock. A portion of a circumferential fluid passage of a pump is enlarged within an angular range of 180.degree. measured from a suction port of the pump and the vapor discharge port is formed at a downstream end of such an enlarged fluid passage, so that fluid flow speed flowing through the enlarged fluid passage is relatively slow and vapored fluid can be effectively exhausted out of the fluid passage.

A negative-electrode active material layer formed between a negative-electrode current collector and a solid electrolyte layer has a line-and-space structure in which a plurality of stripe-shaped pattern elements extending in a Y direction are arranged while being separated from each other. A gradient at each contact point where the stripe-shaped pattern element, the negative-electrode current collector and the solid electrolyte layer are in contact with each other is made smaller than 90°.

A zinc or zinc alloy coated steel sheet has a surface-treatment film formed thereon in a coating weight per one surface of 100 to 600 mg/m2. The surface-treatment film is obtained by applying, onto a surface of the zinc or zinc alloy coated steel sheet, the surface-treatment solution prepared by mixing the following components at specific ratios, the surface-treatment solution having pH of 8 to 10: a silane compound (A) having a hydrolyzable group, obtained from a silane coupling agent (a1) having a glycidyl group, a tetraalkoxysilane (a2), and a chelating agent (a3); a zirconium carbonate compound (B); a vanadate compound (C); a nitric compound (D); and water, and by subsequently heating and drying the surface-treatment solution thus applied.

摘要:
A surface treatment liquid contains a resin emulsion that contains a cationic urethane resin emulsion and/or a nonionic acrylic resin emulsion, a tetraalkoxysilane, at least one silane coupling agent (c) that contains at least one reactive functional group selected from active hydrogen-containing amino group, an epoxy group, a mercapto group, and a methacryloxy group, a chelating agent (d), a vanadic acid compound (e), a titanium compound (f), and water in a specific ratio. The surface treatment liquid has a pH of 3 to 6. The surface treatment liquid is applied to a surface of a zinc-based metal coated steel sheet and dried by heating to form a first layer. Next, a surface treatment liquid containing an organic resin is applied to a surface of the first layer and dried by heating to form a second layer.
摘要:
A connector assembly having a floating structure includes a connector moveably mounted in a cradle housing. A part of this connector connects to and detaches from another connector facing, through a spacing, a connector-mounting window of the cradle housing. The connector on the moveable side is moveable freely within the range of the spacing. An elastic member of flexible material is provided on the exterior of the moveable-side connector and closely contacts and is housed in a housing part formed in the cradle housing. An elastic member restoring force, acting when coupling between the moveable-side connector and the other connector is released, causes the moveable-side connector to return its original position in the cradle housing.
