Patent CA-2100567-A1 (CA)
Inventor: VAN DE WAART PIET
IPC: C12Q1/56
Filed: 1992-11-20
Abstract: A chromogenic assay for determination of Protein S, using an indicator of Factor Xa as a measure of Protein S concentration. This technique utilizes the dependency of activated Protein C on Protein S in order to inactivate a known portion of Factor VIII. Residual Factor VIII is then activated and acts with Factor IXa to activate Factor X. The chromogenic substrate is then cleaved by Factor Xa and the rate of conversion of the indicator molecule is an indirect indicator of free Protein S.

Title: Method and installation for cutting squared timber into boards of a predetermined thickness
Inventor: GOENNER SIEGMAR
IPC: B27L5/06
Filed: 1993-11-15
Abstract: Abstract The present invention concerns a method for cutting squared timber into a number of thin boards.  Individual boards are cut off by a blade from the squared timber in each of the successive cutting machines, essentially in longitudinal direction of the squared timber.  The thickness of the squared timber is selected in such a way that, once an integral number of boards having a predetermined thickness are cut off, a residual board remains which is reduced to the same thickness d as the boards by shaving.  The shaving preferably takes place by placing a planer after the last cutting machine. The installation is equipped with a material feed and a conveying system for removing the cut boards, the cutting machines and the planer are also connected to one another by conveying devices.

Title: Dual gate fet and circuits using dual gate fet
Inventor: SHIGA NOBUO
IPC: H01L29/772
Filed: 1993-11-26
Abstract: ABSTRACT OF THE DISCLOSURE       A dual gate FET structure allowing the FET to achieve a high gain, and circuits utilizing the dual gate FET including a variable gain amplifier and a mixer.  The gate width of the first (source side) gate electrode is different from the width of a second (drain side) electrode.  When the dual gate FET is used in a variable gain amplifier, high gain can be obtained when the drain-side gate is made narrower than the source-side gate.  With the gate widths of the first and second gate electrodes reversed (source-side gate narrower) the FET is particularly well suited for use in a mixer circuit.

The lower portion of each side wall is adjacent the bottom wall and includes an elongated, leg-shaped outer projection which extends along the longitudinal axis of the cell between the upper portion of the side-wall and a point at a certain distance from the bottom wall. Each of the plane-parallel walls has a tongue member adjacent the open end of the tubular body. The tongue members extend outwardly from the border of the open end of the tubular body of the cell in a direction perpendicular to the plane-parallel wall and ends at an outer edge. Each tongue member has an upper surface and a recess, and said tongues and their recesses are positioned symmetrically to each other with respect to the longitudinal axis of the cell. To obtain improve optical properties of the cuvette side walls and bottom wall (used as measuring windows for carrying out electro-optical measurements of the cuvette contents), the leg shaped outer projection on the side-wall containing the injection point of the cuvette is longer and broader than the leg shaped outer projection on the opposite side-wall.
