  • Patent number: 9630283
    Abstract: A plurality of engagement members (20), inserted in a hole in an object to be fixed, which are capable of gripping an inner circumferential surface of the hole are provided, and a wedge face (32) of a clamping rod (15) is engaged on an inner circumference of the engagement member (20) from an upper side. An upper part of a piston rod (55) protruding upward from a piston body (54) of a piston (12) is coupled to a lower part of the clamping rod (15). The engagement member (20), the clamping rod (15), and the piston (12) are provided in a housing (2). An annular valve member (78) is provided between the housing (2) and the piston rod (55).

  • Patent number: 8092830
    Abstract: A process for producing a lactic acid polymer of 15,000 to 50,000 in weight-average molecular weight, the content of polymeric materials having not more than about 5,000 in weight-average molecular weight therein being not more than about 5% by weight, characterized by hydrolyzing a high molecular weight lactic acid polymer, placing the resultant solution comprising the hydrolyzed product under a condition capable of precipitating the objective lactic acid polymer, separating the precipitated lactic acid polymer and collecting them. The lactic acid polymer is useful as a matrix for sustained-release preparations. The sustained-release microcapsule preparation encapsulating a physiologically active substance can fully prevent the initial excessive release of the physiologically active substance from the microcapsules and keep a stable release rate over a long period of time.

  • Publication number: 20120001102
    Abstract: A highly clean and high temperature valve apparatus includes a valve driving unit and a valve casing connected to a bonnet supporting a valve stem slidably. A stem portion has one end positioned in a circumferential wall closed at its two ends by upper and lower covers, and supports one end of the valve stem with its other end extending through the lower cover. The stem portion has its ends supported respectively by first and second bellows for closing an axial through hole of the lower cover tightly. A first pipe communicates with a first space isolated by the first bellows, and a second pipe communicates with a second space isolated by the first bellows. The fluid quantities in the first and second spaces are increased or decreased relative to each other, thereby to drive the stem portion supported in a floating state by the first and second bellows.
