Abstract: A transmission apparatus having an annular casing formed integrally, in its inner face, with a plurality of wave-shaped inner teeth, a plurality of drive roll elements rolling along the toothed inner face of the annular casing, a carrier for swingably supporting the drive roll elements by means of associated connecting element, and a wave generator for cyclically urging the drive roll elements to radially displace while rolling along the toothed inner face, thereby urging the carrier element to exert thereon a drive force.

Abstract: An intestinal microflora-improving agent containing, as an effective component, bacterial cells and/or the water-soluble extracts therefrom, obtained from microorganisms belonging to the genus Streptococcus.

Abstract: In a physiological signals processing system including (a) a A/D conversion means for converting physiological signals into digital signals and (b) a data compression means for reducing the number of data points sampled from said digital signals, the improvement which comprises: said data compression means being provided with a first sampling means for sampling a pair of combined peak points from said digital signals by applying the second order differential conversion to said digital signals, and a second sampling means for sampling level points by the level detection of said digital signals in the portion where adjacent peak points are not combined.

Abstract: A bacterial cell product having hypocholesterolemic and/or hypotriglyceridemic activity in mammals obtained by cultivating a microorganism belonging to the genus Streptococcus and having a N-acetyl-.beta.-D-glucosaminidase activity in an adequate culture medium therefor, and collecting the cultivated microorganism from the resultant culture.

Abstract: An electrochemical method for detecting and classifying microbial cells by applying a sweep potential between a working electrode and a counter electrode while microbial cells are brought into contact with the working electrode and, then, measuring the generated current between the electrodes. Cell numbers and types of cells of microorganisms, animals, and plants are determined from the peak current of cyclic voltammetry.
