Filed: 1985-03-29
Abstract: PURPOSE:A culture device suitable for high-efficiency culture by carrier method, wherein a culture tank is divided into a medium preparing chamber having a medium feed opening, an aerating gas feed part, and a stirring part set at the lower part of the culture tank and a culture chamber laid above the medium preparing chamber by a partitioning material having hole dimension not to pass a carrier laid between the medium preparing chamber and the culture chamber. CONSTITUTION:The medium preparing chamber A is charged with a medium from the medium feed opening 8 and an aerating gas from the sparger 7, respectively, and the medium and the aerating gas are vigorously stirred by the agitating blade 4. The sensor group 6 detects state of the medium, and each control means is regulated to make pH, dissolved oxygen, and temperature fittest. And, the medium after the control and treatment is fed through the porous plate 2 to the culture chamber 2, and suspension culture is performed in the chamber B by carrier method. Cells and carriers used are fed from the seeding opening 13 by a sterile means. In the operation, since stirring is carried out by smoothing the vigorous stirring in the chamber A by the porous plate 8, microorganisms are the cells are prevented from being destroyed. Since the porous plate does not pass the carriers, destruction of the microorganisms in the chamber A can be prevented.

IPC: G02B6/24
Filed: 1991-03-28
Abstract: PURPOSE:To lower coefft. of thermal expansion so as to suppress the contraction by cooling after injection molding and to improve surface roughness by compounding an inorg. filler with a thermoplastic org. high-polymer material. CONSTITUTION:The ferrule 1 is formed by injection-molding the thermoplastic org. high-polymer material compounded with the inorg. filler having <=10mum average grain size. This inorg. filler acts to suppress the contraction by the cooling after injection molding by lowering the coefft. of thermal expansion. Glass beads, SIRASU balloons, glass fibers, carbon fibers, etc., are used for this filler. The ferrule 1 is so formed that its outer peripheral surface 1a to be fitted onto the cylindrical rod of a connector for optical fibers has out of roundness. In addition, a through-holes 2 to be inserted with an optical fiber cable 20 is bored at the axial center of the ferrule. The surface roughness is extremely approximated to the surface roughness of metallic molds by confining the average grain size of the inorg. filler to <=10mum. The ferrule having a desired size and shape is thus obtd.

Abstract: PURPOSE:To achieve damping throughout the entire frequency region of vibration input to a frame by letting electromagnetic force worked on a movable mass elastically supported between an elastic member and the frame, and by offsetting the input vibration in the region of a predetermined frequency not more than that exceeds a resonance point of a spring-mass system. CONSTITUTION:In a condition exciting force does not work from a fixed part, an electromagnet 11 is controlled at the position where a plate spring 9 is deformed by a movable mass 10 to a medium degree by signals from a load cell 12 and a displacement sensor 13. When the exciting force works from the fixed part, this is transmitted to a damping mechanism 5 through an air spring 4, and a detection signal is output from the load cell 12. When the frequency region is less than 2<1/2> times of the resonance frequency of a spring-mass system, the movable mass 10 is moved vertically by the plate spring 9 and the electromagnet 11, whereby the exciting force is offset. When it is more than 2<1/2> times of the resonance frequency, the movable mass 10 is integrated with a supporting body 8 by signals from the load cell 12 and the displacement sensor 13, whereby damping effect by the damping mechanism 5 is stopped, and damping effect by the air spring 4 is thus executed.

On the other hand, a detecting means B is provided which detects an abnormal current generated within the pipeline 2. The generation of the abnormal current being detected by the means B is transmitted to said clutch 15 through an endless rotating belt 45. As a result, the clutch 15 is changed over to a cut-status, releasing the gate 5, making the gate fall down by its own weight and the opening 2a of the pipeline 2 is rapidly closed. Because the  operation of the clutch is performed mechanically, erroneous operation or malfunctioning thereof scarcely happens as compared with the electrically operated one  even at a damp area.
