摘要:
A method for evaluating a residual fatigue life of mechanical parts, consisting of the steps of grinding a surface layer of a mechanical part to be inspected by a minute amount to form an inspection surface, measuring half-width data of an X-ray diffraction intensity curve on the inspection surface, calculating a depth (do) of a fatigue damaged region from a graph of a half-width ratio (H/Ho) versus a depth (d) below the surface layer, and determining a fraction of fatigue life N/Nf on the basis of data of the depth (do) of the defective region versus the fraction of fatigue life N/Nf which were separately obtained from a test piece.

A process for producing a cellulose ester film that is produced by a melt casting method using no solvent at film formation, and that attains reduction of bright spot foreign matter, excelling in planarity, and that attains reduction of staining, excelling in dimensional stability. It is also intended to provide such a cellulose ester film, a polarizing plate and a liquid crystal display unit. There is provided a process for producing a cellulose ester film, characterized by forming into a film a material containing a cellulose ester and an ester compound of 1 to 7.5 distribution coefficient obtained by condensation of a polyhydric alcohol and an organic acid of the general formula: (1) according to a melt casting method.

In an image forming device, a paper feed cassette accommodating a plurality of papers is removably inserted in a cassette accommodating portion of a device main body. A locking member and a lock releasing member maintain a flapper at a prescribed pressed-down position. When the paper feed cassette is inserted into the cassette accommodating portion, after the flapper at the prescribed pressed-down position is unlocked, the flapper is temporarily caught at a position within a vertical swinging range of the flapper. After the paper feed cassette is completely inserted, the flapper is released.

A photoconductive drum device is inserted into and removed from an image forming device main body, horizontally from a side of the image forming device main body. The photoconductive drum device includes a frame, a photoconductive drum and a cover. The photoconductive drum is supported rotatably on the frame under a state in which a part of an outer circumferential surface of the photoconductive drum is exposed. The cover is supported on the frame in a manner capable of swinging. In response to an insertion of the photoconductive drum device into the image forming device main body, the cover swings to an opened position so as not to block off a light path an exposure ray irradiated toward the exposed part of the photoconductive drum. In response to a removal of the photoconductive drum device from the image forming device main body, the cover swings to a closed position to cover the exposed part of the photoconductive drum.

A negative electrode active material of a non-aqueous secondary battery of the present invention includes a first active material, a second active material, and a third active material. The first active material is a carbon material having a D/G ratio of 0.15 or less, where G represents the peak intensity observed in a Raman spectrum from 1578 to 1592 cm−1 and D represents the peak intensity observed in a Raman spectrum from 1349 to 1353 cm−1 of Raman spectroscopy. The D50 of the second active material is 10 μm or less. The second active material includes at least one of a first carbon material having the D/G ratio of 0.2 to 2.0 and a second carbon material having the D/G ratio of 1.0 to 2.0. The D50 of the third active material is 5 μm or less. The third active material contains silicon and oxygen as constituent elements.

An optical cellulose ester film comprising a cellulose ester (A); at least one ester based plasticizer (B) selected from ester based plasticizers composed of a polyhydric alcohol and a univalent carboxylic acid, or ester based plasticizers composed of a polyvalent carboxylic acid and a monohydric alcohol; at least one stabilizer (C) selected from the group consisting of a phenol based stabilizer, a hindered amine based stabilizer, or a phosphorous based stabilizer; and a hydrogen bonding solvent (D).
摘要:
Embodiments of the present invention provide a data recording device capable of achieving desired performance while increasing the convergence rate. According to one embodiment, in a data recording device, an update-width determination unit included in a setting updating unit determines an update-width of a set frequency ƒ in a digital filter according to the size of a position error signal PES, and an update-width adjuster included in the setting updating unit changes the update-width of the set frequency ƒ determined by the update-width determination unit according to the size of the set frequency ƒ. Thus, while the convergence rate being kept properly, the set frequency ƒ can precisely be converged on a frequency of a disturbance component.
