Abstract: A biological simulation method of causing a computer to execute following steps. Firstly, the computer calculates states of a plurality of actins and states of a plurality of myosins in a sarcomere contained in a muscle of a biological body using a model that defines a plurality of states of the actins and a plurality of states of the myosins and transition rates between the states. Secondly, the computer calculates behaviors of the respective actins and behaviors of the respective myosins based on the states of the actins and the states of the myosins, respectively. Thirdly, the computer calculates a behavior of the sarcomere based on the behaviors of the actins and the behaviors of the myosins. Fourthly, the computer calculates a behavior of the muscle based on the behavior of the sarcomere.

Abstract: A biological simulation method includes calculating a behavior of a material contained in a cell of an organ of a biological body, calculating a behavior of the cell based on the calculated behavior of the material, calculating a behavior of the organ based on the calculated behavior of the cell, reflecting the calculated behavior of the organ to the behavior of the cell, and reflecting the behavior of the cell to which the behavior of the organ has been reflected to the behavior of the material.

Abstract: A stopper change device (10) includes an airtight chamber body (21) detachably mountable on a head of a bottle, a gas supply port (19) for supplying N gas to the chamber body, an air vent valve (57) for discharging air from the chamber body, a first supporting structure (28) movable upward and downward for supporting a corkscrew, and a second supporting structure (34) movable upward and downward for containing a substitute stopper. The first and second supporting structures are mutually position changeable, and one of them is selectively placed above an opening of the bottle. When the first supporting structure (28) is placed above the opening, a bottle stopper can be pulled in N gas atmosphere. On the other hand, when the second supporting structure (34) is placed above the opening, the substitute stopper is mountable on the head of the bottle in N gas atmosphere.

Abstract: A fluid extracting device is structured to be capable of extracting only a predetermined amount of a fluid such as wine or the like while a deterioration preventive gas is being supplied to a bottle B and the fluid extracting device (60), which are coupled to each other in an airtight state. Consequently, the partial extraction in a plurality of operations is made possible without causing quality deterioration of the fluid such as wine or the like even after the bottle is once opened. Further, such a structure is provided that the fluid extracting devices (60) having a large number of bottles of wine or the like attached thereto are mounted on a display table at a wine bar or the like.

Abstract: A rotor is formed by rotationally cutting a metal mass mounted on a machine tool shaft under computer control, and also its outer periphery is formed with annular grooves by rotational cutting. The rotor is rotated on a shaft while feeding an abrasive to it, while a workpiece set on a stage movable along three perpendicular axes, i.e., X-, Y and Z-axes, urged against the rotor by moving the stage in the Z-axis direction. The surface of the workpiece is polished by causing the stage to be moved in the X-axis direction and reciprocated in the Y-axis direction, the urging pressure being controlled by measuring it with a pressure sensor.
