A window drain for preventing stains on a building wall and damage caused by frozen rain water, which is installable and sealable easily without impairing the appearance of a building. The present invention relates to a window drain adapted to be positioned at the portion beneath each vertical post of a sash window frame comprising a vertical portion, a sloping portion, a front portion and a horizontal portion for latching itself to an upper portion of an external wall. Further, the present invention relates to the window drain, wherein the horizontal portion has a notch at an end thereof and a sealing pocket. Further, the present invention relates to a window drain, further comprising upstanding portions to regulate a stream of water so that the water is kept between the upstanding portions, at both ends of the window drain wherein one upstanding portion is located at the inner side of the vertical portion of a sash window frame, and the other upstanding portion is located at the outer side of the vertical portion of a sash window frame.

A method of inspecting storage tanks for leaks by means of pressure decrease and increase in the tanks, in which a part of a liquid 6 stored in a tank 1 is discharged to put the tank 1 under vacuum and variations in the pressure in the tank 1 with time are checked, the pressure in the tank 1 is thereafter increased to the level of the atmospheric pressure, and then the liquid which was discharged from the tank is poured back thereinto to put the tank under pressure and variations in the pressure in the tank with time are checked. The method is done by an apparatus designed for inspecting storage tanks for leaks by means of pressure decrease and increase in the tanks, having an air pipe (2), a measuring pipe (3), a liquid feed pipe (4), a liquid suction pipe (5) and an air-tight container (7), which are communicated with a tank (1) to be inspected, a pressure regulator pump (8) connected to the air-tight container (7), and a manometer (11) and a recording air gauge (10) connected to the measuring pipe (3).

A window drain for preventing stains on a building wall and damage caused by (frozen) rain water, which is installable and sealable easily without impairing the appearance of a building. The present invention relates to a window drain adaptable to be positioned beneath a sill of a sash window frame having a vertical portion, a sloping portion, a front portion, and a horizontal portion for latching to an upper portion of an external wall. Further, the present invention relates to a window drain, wherein the horizontal portion has notches at both ends thereof. Further, the present invention relates to a window drain, further having upstanding portions at both ends of the window drain to regulate a stream of water so that the water is kept between the upstanding portions.

Peripheral ribs 34A, 34B of a damper plate 30 are raised from at least two sides along an extending direction of a rotation shaft 31 among four sides forming the peripheral portion of the damper plate 30 and have belt-like outer surfaces. When the damper plate 30 is positioned at a position to close a ventilation path 40, the outer surface of the upper peripheral rib 34A becomes parallel with an upper wall surface 13A of the retainer with a narrow clearance therebetween and the outer surface of the lower peripheral rib 34B becomes parallel with a lower wall surface 13B of the retainer with a narrow clearance therebetween.

The present invention provides a building material in which a coating is applied to a front surface and a side surface is sufficiently adhered to a sealing and method for manufacturing thereof. In a building material in which a coating is applied to a front surface, a coating film on a side surface is removed or reduced by laser irradiation. The part of the side surface in which the coating film has been removed or reduced by laser irradiation has a width of at least 5 mm from a front surface side toward a rear surface side of the building material, or extends over the entire side surface from the front surface side toward the rear surface side of the building material, or is formed more than a part in which coating film is formed.

A method for producing a multilayer ceramic circuit substrate having therein internal conductor patterns comprising W and/or Mo as a main component and surface conductor patterns comprising Cu as a main component formed onto a surface layer of the multilayer ceramic circuit substrate, wherein an intermediate metal layer comprising 40 to 90 wt. % of W and/or Mo and 10 to 60 wt. % of at least one element selected from the group consisting of Ir, Pt, Ti, and Cr is formed in through-holes of the surface layer and on parts of the surface layer in the vicinity of the through holes on the surface layer, whereby the internal conductor patterns and the surface conductor patterns are electrically connected through the intermediate metal layer. The alumina multilayer ceramic circuit substrate enables an excellent bonding strength and electrical conductivity between the internal conductors and the surface conductors and high precision wiring and miniaturization of an electronic circuit part.

An elastic bushing assembly including a rigid sleeve member disposed radially inwardly of an outer sleeve, the sleeve member having a radial flange extending radially outwardly from one axial end thereof, an elastic member interposed between the outer sleeve and the sleeve member, an inner sleeve disposed radially inwardly of the sleeve member, a sliding member interposed between the inner sleeve and the sleeve member and slidable relative to one of the inner sleeve and the sleeve member. A retainer member is located at one axial end of the inner sleeve corresponding to the radial flange of the sleeve member, and a sealing rubber member is in pressed abutting contact with the radial flange of the sleeve member and the retainer member, so as to provide sealing therebetween. The rubber member includes two radially spaced-apart annular sealing lips whose diameters increase in an axially outward direction of the sleeve member away from the radial flange. The outer sealing lip has a tapered distal end face whose diameter decreases in the axially outward direction.
