摘要:
Contamination by microorganism of an aqueous proline solution is prevented by adjusting a proline concentration of the solution to 20% (W/W/) or more. Such solutions are useful as fertilizers and/or plan vitalizers. Preservation of the novel solutions are possible over a significant period of time, allowing for more flexibility in the distribution and application of commercial products made from the solutions.

摘要:
A torque fluctuation absorber includes a disc fixed to a flywheel, a hub fixed to a transmission, first and second side plates fixed to the disc, a damper member, first and second control plates provided at axial both sides of the hub, the first and second control plates being riveted by a stopper pin, a first hysteresis mechanism including first and second low friction members and generating a small hysteresis, and a second hysteresis mechanism including first and second high friction members and generating a large hysteresis. The hub includes a flange portion having a through-hole into which the stopper pin is inserted. A relative rotational angle between the control plates and the hub is defined by a clearance formed between the through-hole and the hub. The first hysteresis mechanism is activated when the relative rotational angle is defined within the clearance.

A torque fluctuation absorbing device includes a first rotational member which transmits a torque from a driving power source, a damping mechanism connected with an input shaft of a transmission, the damping mechanism having a pair of frictional members of approximately annular-shaped fixed at both surfaces of a disc, and a limiter portion for frictionally engaging the pair of frictional members with the first rotational member in a substantially direct manner or in a substantially indirect manner via a pair of frictional plates. An actual length of at least one of the pair of frictional members ranges substantially between 1 percent and 6 percent of a major diameter of the at least one of the pair of frictional members.

An endo-&bgr;-N-acetylglucosaminidase gene encoding the following protein (a) or (b): (a) a protein comprising the amino acid sequence represented by SEQ ID NO: 3; and (b) a protein comprising an amino acid sequence derived from the amino acid sequence represented by SEQ ID NO: 3 by deletion, substitution, or addition of at least one amino acid and having the activity of endo-&bgr;-N-acetylglucosaminidase.
摘要:
A weight member is attached to a rotor so as to forcibly offset a center of gravity of a rotor from a rotating axis, centrifugal force moves two movable weight members to appropriate positions for canceling the unbalance due to the center of gravity offset from the rotating axis, and stoppers restrict the movement of the two movable weight members in a sectoral area opposite to the center of gravity so that the rotor is free from vibrations due to the characteristic angular velocity.

The present invention relates to a novel enzyme having &bgr;1→4 N-acetylglucosaminyltransferase (GnT-IV) activity; a gene encoding the enzyme; a recombinant DNA comprising the gene; a host cell comprising the recombinant DNA; a method for producing an enzyme protein having GnT-IV activity comprising culturing the host cell in a medium; and a saccharide in which the sugar chain is modified using a GnT-IV. According to the present invention, a novel GnT-IV, a method for producing the enzyme and a gene coding for the enzyme are provided. With the GnT-IV of the present invention, it has become possible to produce a saccharide having a branching structure which could not be formed with conventional glycosyltransferases. Thus, the GnT-IV of the invention is useful not only for producing or improving glycoconjugate type pharmaceuticals, reagents and foods, but also for modifying the sugar chain structure of any biopolymer.
摘要:
A scroll compressor having a simple structure is disclosed, which effectively decreases the thrust load imposed on the revolving scroll without degrading the compression efficiency. The scroll compressor includes a casing; a fixed scroll provided in the housing and comprising an end plate and a spiral protrusion built on one face of the end plate; and a revolving scroll provided in the casing and comprising an end plate and a spiral protrusion built on one face of the end plate, wherein the spiral protrusions of each scroll are engaged with each other so as to form a spiral compression chamber. In the above structure, an introduced working gas is compressed in the compression chamber and then discharged according to the revolution of the revolving scroll; a thrust member for thrust-supporting the end plate of the revolving scroll is provided at the back-face side of the end plate of the revolving scroll; a pressure pocket is formed in a face of one of the thrust member and the end plate of the revolving scroll, wherein the face faces the other of the thrust member and the end plate of the revolving scroll; and a high-pressure introduction hole for introducing a high-pressure fluid into the pressure pocket is provided at one of the thrust member side and the revolving scroll side.
