摘要:
To reduce vibration caused by an unbalance of magnetic force generated in a motor portion due to run-out of a rotor in a magnetic bearing apparatus having the motor portion. The vibration of the rotor is detected by means of a radial direction sensor mounted for controlling a magnetic bearing. Then, the vibration in the motor portion is inferred from the run-out of the rotor detected by the radial direction sensor by using the geometric positional relationship between the rotor and the radial direction sensor. The relationship between the unbalance amount of the magnetic force and the amount of run-out of the rotor in the motor portion is formed into the database through experiments or simulation in advance, and the unbalance amount of magnetic force is obtained from this database. Then, the magnetic force resisting the unbalance amount of this magnetic force is generated to offset this unbalance amount.

A propylene polymer composition of high melt tension, which is especially favorable for foam moldings of uniform thickness, and foam moldings thereof having a uniform thickness, are obtained by melt-kneading a polymer mixture of a specific ethylene polymer (A) and a specific olefin multi-stage polymer (B) to satisfy the following formula: Log(MS)>0.91−0.23×Log(MFR(T))

A hybridoma producing a monoclonal antibody recognizing the C-terminus of human brain natriuretic peptide (hBNP) was cultivated in a medium or the abdominal cavity of a mouse to recover the monoclonal antibody from the medium or ascites accumulated in the abdominal cavity. An immunoassay for hBNP was established using the monoclonal antibody. The immunoassay for hBNP of the invention is so sensitive that the minimum detection limit is 1 pg/ml and can therefore determine the hBNP level in blood plasma directly, without the extraction of hBNP from blood plasma. It is useful for diagnosing diseases such as hypertension and the like, and states of the heart, kidney, and the like by using the increase/decrease of the hBNP level as an index.

A turbo molecular pump has a rotor having rotor blades arranged in multiple stages. Each of the rotor blades has a proximal end fixed to the rotor and a distal end. Stator blades are arranged in multiple stages. Each stator blade has a proximal end and a distal end. The rotor blades and the stator blades are alternately arranged in spaced-apart relation in an axial direction so that a spatial clearance between the proximal end of each of the rotor blades and the distal end of an adjacent stator blade is smaller than a spatial clearance between the distal end of each of the rotor blades and the proximal end of the adjacent stator blade. Each of the rotor blades comprises a cantilever member having upper and lower surfaces. At least one of the upper and lower surfaces of the cantilever member is contoured to define a flexure curve line represented by the formula &Dgr;=(WL4/8EI)(1−(4X/3L)+(X4/3L4)), where E (kgf/mm2) represents the Young's modulus of the material of the cantilever member, I (mm4) represents the geometrical moment of inertia of the cantilever member, L (mm) represents the length of the cantilever member, W (kgf/mm) represents a load distributed on the cantilever member, and &Dgr; represents a flexure amount of the cantilever member at a distance x (mm) from the distal end of the cantilever member.
摘要:
An application program for generating performance data of a user input musical score performs a modifying process of modifying only a note with a musical sign such as a turn sign, so that as the generated performance data is reproduced, unnatural musical sounds are generated. For example, as a player uses a turn rendering with an acoustic piano or the like, there is a tendency that a key depression force for a note just after the turn rendering also becomes weak. With conventional techniques, however, this state cannot be automatically realized. In order to generate performance data whose notes are coupled naturally, output performance data is first generated at Steps SP10 or SP18 for a note (subject note) with a turn sign. Then, a velocity of performance data for a note (related note) positioned immediately after the subject note is weakened at Step SP12 or SP20.

摘要:
A high molecular weight polyethylene prepared by preliminary polymerization is added at the time of main polymerization of an olefin, for example, propylene, to prepare an olefin (co)polymer composition comprising the above high molecular weight polyethylene finely dispersed as fine particles in the polyolefin, such as polypropylene, and a cross-linked structure is formed in the olefin (co)polymer composition. This process can provide a modified olefin (co)polymer composition improved in the strength in a molten state in terms of melt tension or the like and in crystallization temperature and excellent in moldability such as high-speed producibility, and a molded modified olefin (co)polymer composition excellent in properties such as heat resistance and rigidity.
