Disclosed is an implantable two-chamber system for supporting the left ventricle of the heart. Each of the two pumping chambers (1, 1') of said two-chamber system has the shape of a ventricular bag comprising an inlet (11) that is embodied at one end at an acute angle (α) to an outlet (12), directly next to said outlet (12). Furthermore, a pressure plate (2) is rotatably mounted externally in two arms (5) which are movably retained on the output shaft (9) of a drive unit (15) such that the center of motion (8) of the arms (5), which lies on the output shaft (9), is located on the side of the pumping chambers (1, 1') facing away from adapters (4, 4'), and thus outside said pumping chambers (1, 1'). The angle between the inlet (11) and the outlet (12) of each pumping chamber ranges from 30° to 60°. The maximum width in the inlet and outlet zone of each of the pumping chambers (1, 1') amounts to about 65 to 72 percent of the length of the respective pumping chamber. In addition, each of the ventricular pumping chambers (1, 1') is provided with a bulge (13) adjacent to the inlet (11) in order to reduce the resistance to fluid flow, said bulge (13) having a length ranging from 10 to 15 percent of the length of the pumping chamber. The diameter of the inlet (11) and the outlet (12) amounts to about one third of the length of the pumping chamber.
摘要:
The object of the present invention is to provide a multifunction ignition device integrated with a spark plug for conserving space by integrating a spark plug (C), ignition coil (A), and fuel injection device (B) in a single enclosure and for making a high fuel efficiency engine design possible and allowing spark plug electrode replacement, thereby reducing waste during plug maintenance. The multifunction ignition device of the present invention includes an ignition coil (A) directly connected to a plug top of an internal combustion engine; the ignition coil, a fuel injection valve (B), and a fuel injection nozzle (10) are housed in a single enclosure; and a center electrode (10a) and a ground electrode (9) of the spark plug (C) are removably mounted at the bottom end of the enclosure.

In the pouch manufacturing method of the present invention, a valve member (103) which restricts the movement of the contents when the pouch is formed is conveyed in accordance with the conveying of web-form body members (101,102) that form the pouch, and this valve member (103) is welded to the body members (101,102) in a state in which a sealing preventing member (106) is interposed on the side on which the contents pass through; accordingly, pouches that have a valve function such as a reverse flow preventing function or the like can be continuously manufactured.
摘要:
Cup-shaped containers can be turned over and transferred with good stability from a sterilization-washing zone to the filling-sealing zone inside an aseptic chamber, and admixture of odor or microorganisms is prevented. The first conveyor 2 for conveying the cup-shaped container 38 in an inverted state and a second conveyor 3 for conveying the container in an upright state downstream of the first conveyor 2 are disposed in series in substantially the same plane inside a continuous aseptic chamber 1. A container supply device, a container sterilization device, and a container washing device are disposed successively along the first conveyor 2. A contents filling device 40, a lid material sealing device 41, and a device for discharging the sealed cup-shaped container are installed successively along the second conveyor 3. Sterilization and washing are performed in an inverted state, while conveying the container with the first conveyor 2. The washed container is turned over and transferred from the first conveyor to the second conveyor 3 and the contents filling and lid sealing are performed on the second conveyor.
摘要:
In order to desirably prevent leakage of a working fluid from the tip clearance to reduce loss of a heat drop of the working fluid, a first corresponding blade of a second stationary blade row, which corresponds to a first reference blade of a first stationary blade row, is disposed in a position distant by 2L from the position of a lower end of a rotor blade in the direction of movement of the rotor blades when the rotor blade makes the closest approach to a lower end of the first reference blade. It should be noted that L is a value obtained by multiplying the average time T required for the high-pressure working fluid to pass through the rotor blade by the traveling speed U of the rotor blade. On the other hand, a second corresponding blade of the second stationary blade row, which corresponds to a second reference blade of the first stationary blade row, is disposed in a position of a lower end of a rotor blade when the rotor blade makes the closest approach to a lower end of the first reference blade.
