Abstract: A water-tight fiberglass septic tank is strong enough to withstand live loads. The fiberglass septic tank is preferably designed with integral ribs to for structural strength. In one preferred embodiment, the tank is made in two unequal halves. The lower half comprises the major portion of the tank and includes a bottom, two endwalls and two sidewalls. The upper half comprises a cover. This arrangement allows the horizontal seam to be placed above the internal waterline, thereby protecting the seam from exposure to sewage. At least one of the endwalls includes a raised top portion that allows a pipe to be located near the top of the lower portion without passing through the seam between the upper and lower portions of the tank. The endwalls are also curved to allow for angled inlet and outlet pipe connections. The ribs are preferably internal and hollow. The lower portion of the tank is also preferably flat bottomed. A provision has been made for a self-locating baffle if required.

Abstract: A method of populating multiple data marts in a single operation from a set of transactional data held in a database in a single aggregation process, in which aggregate values are calculated only once, a determination is made as to which output data marts required the aggregate value, and the aggregate values are output to the appropriate data marts. Dimension data associated with the output aggregate records is also output to the appropriate data marts.

Abstract: A radiation-sensitive resin composition comprising (a) a resin represented by a copolymer of p-hydroxystyrene and t-butyl (meth)acrylate and a copolymer of p-hydroxystyrene and p-t-butoxystyrene, (b) a photoacid generator, and (c) a quaternary ammonium salt compound represented by tetramethylammonium adamantanecarboxylate, tetramethylammonium oxalate, tetraethylammonium pyruvate. The radiation-sensitive resin composition is capable of producing a rectangular resist pattern while preventing the top edge of the pattern from rounding, which is a big problem in microprocessing of design dimensions of about 0.20 &mgr;m with a thin film. The radiation-sensitive resin composition is highly sensitive to deep ultraviolet radiation, X-rays, and charged particle rays and exhibits excellent sensitivity, resolution, and the like.

Abstract: A radiation-sensitive resin composition comprising a solution of an alkali-soluble resin and a radiation-sensitive compound in a solvent comprising a monooxymonocarboxylic acid ester. This composition has a high storage stability (i.e., a very small amount of fine particles are formed during storage) and is suited for use as a resist for making integrated circuits.

Abstract: A multiple-speed transmission wheel hub for imparting torque to a drive wheel includes a hub shell formed around a wheel axis and a clutch wheel formed around the wheel axis and axially movable between at least first and second speed positions. First gearing couples the clutch wheel to the hub shell when the clutch wheel is in the first position producing a first transmission speed. Second gearing couples the clutch wheel in the second speed position with the hub shell producing a second transmission speed. A speed-shifting cam is disposed on the axis and axially rotatable between at least first and second speed positions, with helical segments formed on a surface of the clutch wheel facing the cam, the helical segments coupling to the cam to translate rotation of the cam into axial displacement of the clutch wheel both from the second speed position to the first speed position and from the first speed position to the second speed position.

Abstract: The injector comprises a tip having at least one outlet orifice (7) for fuel delivered to an engine combustion chamber. A ceramic coating (14) is deposited on the external face of the tip, preferably in a kink (12) bounding a recess in this external face, at least around and immediately downstream of the outlet orifice (7) relative to the direction in which the fuel is delivered. This invention is applicable to fuel injectors with a ceramic coating to protect against deposits of carbon oil for use with spark-ignition and direct injection internal combustion engines.

Abstract: A shell featuring a main body formed of a hard and flexible sheet-like substance, such as stainless steel, is substituted for the rubber blanket of a blanket cylinder in a lithograph offset press. Perforating material that includes spaced teeth with flat edges are mounted on the impression cylinder and engage the main body of the shell to form perforations without shoulder defects. Slitting or scoring may also be accomplished by the arrangement. Stabilizing strips are positioned upon the main body of the shell in sheet-fed press applications. Flexible rubber sheets are mounted to the ends of the main body. Blanket bars are also mounted to the flexible rubber sheets. The blanket bars engage the lock-up of the blanket cylinder to secure the shell in position.

Abstract: A brake or clutch operating device having a hand lever pivotally attached to a mounting bracket secured to a handlebar, the hand lever rotatable about a rotation axis that is offset from the pivot axis, and a transmission mechanism for converting a rotational force applied to the hand lever into a rectilinear force drawing the hand lever toward the handlebar. The transmission mechanism and hand lever configured to force rotation about the rotation axis in response to rotation of the hand lever about the pivot axis, the resulting compound motion of the hand lever following the natural arched motion of the rider's fingers during lever actuation.

Abstract: A liquid waste disposal and canister flushing system and method for a medical canister including a lid with at least first and second ports features a cabinet with an opening and a sink with a drain positioned therein.

Abstract: The essence of the method resides in that a recess (2) is made in the mounting surface, having the dimensions exceeding those of a chip (3). The chip (3) is gripped with a gripping member appearing as a tool (4) having a flat end and a capillary hole (5) flaring up towards the tool end, and is oriented above the recess (2). Before pressing the chip (3) into the recess (2) a dosed amount of a binder (6) is placed therein. The chip (3) is pressed into the binder (6) until the part of the flat end of the tool (4) which extends beyond the outlines of the chip (3) thrusts against the mounting surface. The pressing-in procedure is stopped as soon as the face surface of the chip (3) is coincided with the surface on which the recess (2) is made, whereupon the gripping tool is disengaged.
