摘要:
An optical measurement system which manages whether an optical property of a sample falls within a predetermined management range. The optical measurement system has a measuring device for measuring the optical property value of the inspected sample, a reader for reading an attribute identification information of an identification tag attached to the sample, and a storage section for storing optical property management information concerning a plurality of kinds of samples each in a manner corresponding to attribute identification information of each sample. A controller in the optical measurement system reads out from the storage section the optical property management information corresponding to the attribute identification information of the sample read by said reader, and compares the optical property management information with the optical property value of the sample, and then determines whether the optical property value falls within an allowable range in the optical property management information.

A stator is constructed by winding excitation coils around respective main poles. A rotor is constructed by fixing a first rotor unit, which consists of a pair of rotor cores and a magnetic material sandwiched between the rotor cores, and a second rotor unit, which has the same construction as the first rotor unit, to a rotation shaft. The rotor is assembled to the stator to form an assembled body. The magnet material of the first rotor unit is magnetized in the axial direction by a magnetizing flux passing through a half of the assembled body in the axial direction. The magnet material of the second rotor unit is magnetized in the axial direction in an opposite polarity by a magnetizing flux passing through the remaining half of the assembled body in the axial direction.

A stepping motor includes: a stator having main magnetic poles each having small stator teeth on its tip, a core-back portion that connects outer portions of the poles, and windings wound around the poles; and two sets of rotor units that are arranged in an axial direction and face the stator with an air gap therebetween. Each rotor unit consists of two rotor cores that are separated in the axial direction and a magnet sandwiched thereby and magnetized in the axial direction. Each rotor core has small rotor teeth around its outer surface. The rotor cores of each rotor unit are deviated by ½ pitch of the small rotor teeth, and the two rotor units are arranged to make the magnetic polarities of the small rotor teeth of the adjacent two rotor cores identical. A magnet thickness Tm and a rotor core thickness Tc satisfy 0.25≦Tm/Tc≦0.45.

A protective film for polarizing plate is disclosed in which an contact angle of the surface in contact with a polarizer with respect to pure water is less than 55° and the surface in contact with a polarizer becomes hydrophilic due to a plasma treatment.In such a manner, the protective film for the polarizing plate is readily adhered with a polyvinyl alcohol film employed as a polarizer and can be produced employing processing which is safe in work and does not adversely affect the environment. Thus highly efficient protective film for the polarizing plate, which exhibits excellent adhesion with a polyvinyl alcohol film, and a polarizing plate employing the same, are provided.

Read buffers (RB0-RB3) are capable of holding data read out from a plurality of memory blocks (BNK0-BNK7) that are capable of parallel operation in response to a state in which the read data cannot be externally outputted from an external interface means; and, selection means (40, 41, 42) are provided for selecting data read out from one of the memory blocks, or data read out from one of the read buffers, and for feeding it to the external interface means, while the external-output-incapable state is not present. In this way, when there is a possibility that an output of read data will cause a resource competition, this read data is stored in a read buffer, and when there is no such possibility, then the read data can be externally outputted directly, thereby improving the throughput of read data output operations.
摘要:
A stator of the stepping motor of the invention includes an annular shaped yoke portion, a stator iron-core having twelve stator main poles each having a plurality of small teeth on the tip end thereof and stator coils wound in the stator iron-core as three-phase winding. The stator rotatably supports a hybrid type rotor having a cylindrical permanent magnet that is sandwiched between a pair of rotors each having pole teeth around the circumferential surface to be opposite to the small teeth. Second, third, fourth and fifth harmonic components are removed by composing cogging torque of the respective phases by means of the three-phase twelve-pole construction. Any one harmonic component of the cogging torque among the second to fifth harmonic components is independently erased by making a difference between the small teeth pitch and the rotor teeth pitch, thereby the selected harmonic component is doubly erased.
