Abstract: Abstract of the Disclosure:         In order to solve a symmetric linear system given by Au = b, where A represents a symmetric coefficient matrix equal to a three-term sum of a diagonal matrix plus an upper triangular matrix plus a lower triangular matrix, b represents a right-hand side vector, and u represents a solution vector, a device calculates the solution vector by using the right-hand side vector, the diagonal matrix, and the upper triangular matrix.        Supplied with an array (JA) representing a column number of the upper triangular matrix, a pointer array constructing section (11) constructs a pointer array (JL) which points to the lower triangular matrix.  Supplied with an array (AA) and the array (JA) which collectively represent a combination of the diagonal matrix and the upper triangular matrix, a matrix decomposing section (12) decomposes the array (AA) into an approximate matrix (M) which approximates the symmetric coefficient matrix.          A first product calculating section (16) calculates a first product vector (y) by using the array (AA), the array (JA), a first vector (x), and the pointer array (JL).  A second product calculating section (17) calculates a second product vector (y') by using the approximate matrix (M) and the second vector (x').  An iterative calculating section (18) carries out iterative calculation on the array (AA), the array (JA), an array (B) representing the right-hand side vector, the first and the second product vectors (y) and (y').  The (Abstract of the Disclosure continued) iterative calculating section (18) iteratively provides the first and the second product calculating sections (16) and (17) with the first and the second vectors (x) and (x'), respectively.  The iterative calculating section (18) produces the solution vector (u). The device may be supplied with the lower triangular matrix instead of the upper triangular matrix.

Granted: 1994-01-25
Abstract: ABSTRACT OF THE DISCLOSURE A paintbrush caddy (50 or 150) embodying the concepts of the present invention utilizes a shelf plate (54,154) having a longitudinal  length sufficient for supporting a paintbrush (80) thereon. The forward end portion of the shelf plate(54,154) may be affixed to a vertically depending apron (52,152) positioned at an obtuse angle (.alpha.1) relative to the shelf plate (54,154) such that a paintbrush (80) supported on the upper surface of the shelf plate (54,154) is positioned at an acute angle (.alpha.2) with respect to a horizontal reference when the caddy (50,150) is used. An upwardly extending stop plate (60,160) is also affixed to the shelf plate (54,154) at its forward end portion, and the stop plate (60,160) is penetrated by at least one drain aperture (66,166) that opens through the stop plate (60,160) at the level of the upper surface (54a,154a) on the shelf plate (54,154). The disposition of the shelf plate (54,154) and the stop plate (60,160) define receptacle (62,162), and the bristle portion (84) of the paintbrush (80) is received within that receptacle (62,162). A clamping means (70,90,170) is secured to either the under surface (54b) of the shelf plate (54) or the rear surface (152a) of the apron (152), and the damping means (70,90,179) is of such width (w) that a portion of a paint container (12) can be grasped between the clamping means (70,90,170) and the apron (52,152) to stabilize the caddy (50,150) relative to the paint container (12). The clamping means (70,90,170) thereby allows the brush caddy (50,150) to be presented in such a way as to position the paintbrush (80) for ready access when needed and for providing paint drainage from the brush, along the upper surface (54a,154a) of the shelf plate (54,154), through the drain apertures (66,166), downwardly over the apron (52,152) and into the paint container (12).

Inventor: HEGNER FRANK
IPC: C04B37/02
Filed: 1992-11-03
Granted: 1996-06-25
Abstract: To avoid any deterioration of the surface properties of objects of ceramic, glass, or a single-crystal insulat-ing material which are subjected to a vacuum temperature process, a thin layer of a spin-on glass solution with a silicon-dioxide equivalent of not more than 10% is applied to the objects by spinning or spraying prior to the vacuum temperature process. This is particularly important to avoid the strong moisture dependence of capac-itive or resistive pressure sensors having a substrate and a diaphragm to be joined together, forming a chamber sealed at least at the edge. The diaphragm is covered with a layer of silicon carbide, niobium, or tantalum serving as one capacitor electrode, or the surface portion of the diaphragm which will lie within the chamber is coated with at least one strain gage; the portion of the substrate surface which will lie within the chamber is coated with at least one additional capacitor elec-trode or, in the case of the resistive pressure sensor, not coated therewith; over the entire surface portion of the substrate and diaphragm thus coated, a thin layer of the spin-on glass solution is applied and dried;     contact is made to the capacitor electrodes or strain gages through the substrate and/or diaphragm, and sub-strate and diaphragm are brazed together by means of a ring-shaped part of active brazing material, which also serves as a spacer, or by means of a sufficient amount of active brazing paste.
