Abstract: In an energy converter of the type utilising a series-resonant bridge circuit (1), containing at least two thyristors (6A, 7A, 6B,7B) diodes (8A, 9A, 8B, 9B), antiparallel connected thereto and a high-frequency output transformer (12), and an energy buffer (2), a control circuit (3) is incorporated for generating trigger pulses for the appropriate thyristors in response to the energy of the buffer (2). The energy converter comprises a switching circuit (24) incorporated in at least one of the supply lines of the supply source to the series-resonant circuit for ensuring that the diode, antiparallel connected to the last-conducting thyristor, starts to draw current immediately after this thyristor is blocked. The control circuit (3) furthermore generates signals indicative of the presence of current flowing through the diodes (8A, 9A, 8B, 9B) which signals control the supply of the trigger pulses to the thyristors (6A, 7A, 6B, 7B).

Abstract: Monoclonal antibodies capable of specifically recognizing fodrin and having a subclass of G 2  (G 2a , G 2b ). The antibodies can detect fodrin of various origins in addition to animal species and from denatured to native origins. Some of the obtained monoclonal antibodies can detect a third subunit which cannot be detected and polyclonal antibodies. The antibodies can find wide applications to cancer, differentiation of cells, myotonic dystrophy, etc. Particularly with cancer generation, a monoclonal antibody (15Al) capable of specifically recognizing a fodrin p subunit enables diagnosis of the extent of malignance of cancer and differentiation. Identification and determination of fodrin which is a cell-backing protein and which participate in an information transfer system are important for clarifying the mechanism of various diseases, and hence the monoclonal antibodies are quite important from the medical and physiological points of view.

Abstract: The present invention involves a method of producing cellulose. This method comprises inoculating a quantity of nutrient medium comprising a polysaccharide derivative such as carboxymethylcellulose (CMC) with a cellulose-­producing microorganism. The inoculated medium is then aerobically incubated to facilitate the production of cellulose. The step of substantially drying the cellulose may be added for certain products. Substantially dried cellulose resulting from this procedure is highly absor­bent, tending to retain its absorbent properties during repeated wetting and drying, and is usable where such absorbency is desired. 
     A subject of the present invention is a composition of matter consisting essentially of such cellulose in a native or substantially dried form. Microbial cellulose produced in the presence of carboxymethyl cellulose may be substantially dried by many means known to those skilled in the art. This drying may be, for example, by washing with a non-aqueous hydrophilic solvent or by air-­drying. Preferred non-aqueous solvents include alkyl alcohols or ketones having less than about six carbon atoms. When such non-aqueous solvents are used to dry the CMC-produced cellulose, the dried cellulose may have a resilient structure and possibly an elastic nature.
