Abstract: ABSTRACT      Apparatus is disclosed which serves to move a carriage in one direction over a predetermined distance at a substantially uniform velocity and for returning the carriage at a varying velocity so that a film web which is delivered at a constant velocity is intermittently advanced relative to a welding device, which fixed to a frame.  The apparatus com-prises a lever, which is adapted to be pivotally oscil-lated by a drive and which by means of a first guide provided on said lever and extending along said lever and a slider or roller cooperating with said guide imparts a motion to said carriage, which is movable in tracks in a plane which is parallel to the plane in which the lever is pivotally movable.  The slider or the bearing for the roller is mounted on a holder, which is guided for a displacement along a line, which constitutes the base of an isosceles triangle, the sides of which are defined by the lever at the end positions of its pivotal movement.  In order to provide such an apparatus which is more compact and space-saving, the means for driving the lever      comprise a crank, which revolves in a plane that is parallel to the plane in which the lever      is pivotally movable, and said crank is carried by a driven crankshaft and carries a crankpin, which carries a slider or a roller, which is movable in a second guide provided on the      , which second guide is disposed on that side of the lever which is opposite to the first guide     .

Filed: 1987-11-04
Granted: 1992-07-14
Abstract: ABSTRACT OF THE DISCLOSURE           A liver function testing apparatus and method are disclosed in which light sources expose vital tissue to light of a first wavelength absorbed by specific dye dosed into blood of the vital tissue to be taken in and removed by the liver, and light of a second wavelength not absorbed by the dye.   Optical pulses obtained from the vital tissue are received by a light receiving element, the receiving output of which is sampled by an A-D converter to be converted into digital signals.  Variable components in the blood included in the sampling outputs are determined as coefficients of linear functions, to perform biocalibration.  A value correlated with specific dye concentration in the blood is operated on the basis of sampling outputs during a prescribed period after injection of  the specific dye and the determined coefficients,  so that a coefficient of a simulation function as a function of time is obtained by using the method of least squares and a blood plasma disappearance rate and a retention rate are obtained on the basis of the coefficient.
