An apparatus includes a rotation member having a pair of floats having different weights. The floats are fixed thereto at such positions that turning moment is produced due to one of a floating force and a sinking force for each of the floats. The apparatus further includes a rotation angle sensor for sensing a change in rotation angle of the rotation member as a change in concentration of the solute in the solution.

The present invention is a method for identifying a Most-Probable-Point (MPP) in original space obviating the need for a probability transformation, for use in first order/second order reliability analysis. It comprises generating the linear approximation of a limit-state-function, g(x) about the median, mean point, or mode of random variables, x of g(x). g(x) is defined so that g(x)f0 denotes a failure set. The Most-Probable-Point-Locus (MPPL) of g.sub.1, MPPL.sub.1, is constructed by the steps...

A size checking apparatus is employed to check sizes or dimensions of a work. The size checking apparatus includes: a constant speed transporting unit for a work; a measuring unit for continuously measuring a distance from a measurement sensor to a measuring position of the work while the work is being transported; a trigger signal generator for sensing that the work has passed and for commencing an acquisition of a measurement value by the measuring unit in response to a trigger signal; a pulse...

When a component is placed on a circuit board, a placement position is determined by method of elastic center. Then, it is determined whether the component was placed on the circuit board. After that, connectors are routed between the component and a design candidate component which is already placed. After that, the next component is set, and the above mentioned packaging processing is repeated.

A modular well for a wastewater lift station includes multiple well sections. Each of the well sections has at least one mating feature allowing it to be joined to at least one other well section and to form a liquid tight seal. The well is formed by vertically mating the well sections together. One of the well sections has an inlet opening, and the same or a different well section has at least one outlet opening.

The invention relates to a device for displacing an object, which device includes a drive device for moving the object along an axis of motion, a control unit which is coupled to the drive device, a set-point generator which is coupled to the control unit and is arranged to determine from secondary conditions a jerk set profile and set points for a plurality of sampling periods for a trajectory to be traveled and to apply the set points to the control unit per sampling period. A problem solved b...

An ABS adhesive for joining ABS articles, such as pipes, comprises: (a) about 10 to 35 wt% ABS resin; and (b) about 40 to 60 wt % dibasic esters and, optionally, at least one solvent selected from the group consisting of 0 to about 30 wt % methyl ethyl ketone and 0 to about 10 wt % acetone. The VOC level of the ABS adhesive composition of the invention is at or below the allowed maximum value of 350 g/l. The lap shear strength ranges from about 400 to 700 psi, which is deemed adequate for most n...

A method and apparatus are provided for allocating tolerances. A total tolerance is specified (218) to be allocated among a plurality of variable tolerances each having an associated assembly feature. For each associated assembly feature, an associated first tolerance point is defined (202) at which a further decrease in a stringency of the variable tolerance fails to significantly decrease a cost of achieving the variable tolerance. For each associated assembly feature, an associated second tol...

Measurement of lengths for determining the outside diameter, wall thickness or inside diameter of tubes which, must be maintained to close tolerances. A mandrel of tungsten carbide having a coaxial projection of knife-edge width is postioned so that its transverse dimension intersects the beam and is parallel to the plane of the beam. A first length is measured between the end of the beam and the nearest point on the projection. A tube is mounted on the projection with its its longitudinal axis ...

An apparatus for controlling operation of a processing machine has a computer preferably with a computer aided design program configurable to model a kinematic velocity profile of a point of interest on a machine to be controlled. A graphical user interface on the computer enables an operator to select desired velocity points for a motor drive controlling motion of the point on the machine. A curve fit is applied to the velocity points to realize a desired velocity profile for the motor drive an...
