摘要:
A housing (20) is formed with pairs of projections (31A, 31B) at opposite sides in a width direction perpendicular to a connecting direction and supporting shafts (29) located between the projections (31A, 31B) at the opposite widthwise sides and behind the projections (31A, 31B) in the connecting direction and adapted to rotatably support a lever (60). The lever (60) is formed with stoppers for preventing a rotation of the lever (60) by being engaged with the projections (31A) on one widthwise side at a connection start position. Further, the lever (60) is formed with pressing portions (72) for correcting a connection posture of the housing (20) by pressing the projections (31B) on the other widthwise side in the connecting direction when the housing (20) is inclined from a proper connection posture with respect to a mating housing (80) in a process reaching a connection position.
摘要:
A lever (40) is rotatable about shafts (19) between a projecting position where side plates (42) project to a large extent from the rear end of a housing (10) and a retracted position where the side plates (42) do not project far the rear end of the housing (10). Projecting pieces (61) project forward on front end edges of the side plates (42) and leading ends of the projecting pieces (61) overlap the rear end of the housing (10) in forward and backward directions at the projecting position. At the projecting position, spaces (63, 64) are formed by the opposite side edges of the projections (61), the front edges of the side plates (42) and the rear end of the housing (10). These spaces include escaping spaces (63) that receive cam followers (85) on the mating housing (80) at the retracted position.
摘要:
A precursor sol of aluminum oxide includes a solvent and particles containing a hydrolysate of an aluminum compound and/or a condensate of the hydrolysate, in which the particles have an average particle size of 2.5 nm to 7 nm. A method for producing an optical member includes the steps of feeding the precursor sol of aluminum oxide described above onto a base to form an aluminum oxide film and immersing the aluminum oxide film in hot water with a temperature of 60° C. to 100° C. to form a textured structure comprising aluminum oxide boehmite.
摘要:
Tanks of a first heat exchanger have plane sections perpendicular to bottoms having a plurality of tube insertion holes formed therein. Tanks of a second heat exchanger with circular cross sections have bottoms having a plurality of tube insertion holes formed therein. The axes of the tube insertion holes of the first and second heat exchangers are held in parallel with each other. The second heat exchanger is in contact with the plane sections of the first heat exchanger tank.

The invention provides a method of producing a through-hole, a substrate used to produce a through-hole, a substrate having a through-hole, and a device using such a through-hole or a substrate having such a through-hole, which are characterized in that: a through-hole can be produced only by etching a silicon substrate from its back side; the opening length d can be precisely controlled to a desired value regardless of the variations in the silicon wafer thickness, and the orientation flat angle, and also regardless of the type of a silicon crystal orientation-dependent anisotropic etchant employed; high productivity, high production reproducibility, and ease of production can be achieved; a high-liberality can be achieved in the shape of the opening end even if temperature treatment is performed at a high temperature for a long time; and a high-precision through-hole can be produced regardless of the shape of a device formed on the surface of a substrate.

An oil cooler mounting structure includes: a heat exchanger tank main body that is made of aluminum and has an oil cooler mounting hole in a wall surface thereof; an oil cooler that is made of aluminum, has an insertion hole for an oil introducing/discharging pipe formed in a seat portion, and is mounted inside the heat exchanger tank with a plurality of projecting pieces erected around the circumference of the insertion hole; a patch that is made of an aluminum-containing brazing filler metal and is arranged on the outer circumference of the projecting pieces of the oil cooler; and the oil introducing/discharging pipe that is inserted into the insertion hole formed in the seat portion of the oil cooler. In such oil cooler mounting structure, the oil cooler is mounted onto the heat exchanger tank main body by having the plurality of projecting pieces of the seat portion projected outside through the oil cooler mounting hole, by setting the patch through the outer circumference of the plurality of projecting pieces of the seat portion, and by bending the plurality of projecting pieces toward the patch.
摘要:
An insulating film is formed on the surface of the base of a semiconductor, and a portion of the insulating film is removed to cause the surface to appear outside. The exposed surface is terminated with hydrogen, and then energy beams are applied to selectively remove the terminating hydrogen. Metal is selectively deposited on the portion terminated with left hydrogen atoms.
