摘要:
A sheet feeding mechanism for feeding stacked sheets one by one from a sheet magazine includes a plurality of suction cups coupled to a vacuum suction device for attracting one sheet at a time, and an arm member on which the suction cups are securely mounted. At least one rotatable bearing is operatively coupled to the arm member and rollingly movable in a guide groove having at least one curved or bent guide opening. The bearing is movable by a slider in and along the guide opening to angularly move the arm member and hence the suction cups for thereby swaying and feeding a sheet held by the suction cups.

A film package has a flexible light-shielding bag with a stack of sheet films stored therein, the flexible light-shielding bag having at least opposite ends sealed in a direction in which the flexible light-shielding bag can be pulled out, said opposite ends being folded back on one surface and joined together by a seal. The film package is placed in a holder which can be inserted into and removed from a main body of a film loading device.

摘要:
The object of the present invention is to provide a method for efficiently producing a polyester copolymer consisting of 3-hydroxybutyrate and lactate via microbial fermentation with the use of a sugar as a starting material. The method may comprise culturing a recombinant microorganism expressing: a protein capable of catalyzing the transfer of CoA to propionic acid and/or lactate; a protein capable of catalyzing the formation of acetoacetyl-CoA from two acetyl-CoA molecules; a protein capable of catalyzing acetoacetyl-CoA reduction; and a protein capable of catalyzing polyhydroxyalkanoate synthesis. According to the production method, a polyester copolymer consisting of 3-hydroxybutyrate and lactate can be efficiently produced using an inexpensive carbon source as a starting material, and thus the production cost of a biodegradable plastic can be reduced.

摘要:
In the method for separating and purifying histidine from a culture containing the amino acid, the culture containing histidine and microbial cells is charged onto the top of a column filled with a carrier particle whose particle size is 350 μm or more and which has an ability to adsorb histidine and then an eluent is passed through the column whereby accomplishing the separation and purification of histidine, and preferably in the step mentioned above, a strong acid cation exchange resin is employed as a carrier particle whereby accomplishing the separation and purification of histidine.
