A highly reliable magnetic head is provided where fluctuation in the form of the upper magnetic pole is prevented and recording density is improved. The magnetic head is equipped with a recording head where a lower tip magnetic pole and an upper tip magnetic pole are formed facing one another on both sides of a write gap and a coil is disposed on a rear side of the lower magnetic pole. The lower tip magnetic pole is provided with an apex part by forming the surface on the rear side on which the coil is disposed as an inclined surface, and an insulating layer that covers the coil is formed to the rear of the lower tip magnetic pole.

An optical pickup device is provided which includes a double-wavelength objective lens (34) that collects a light beam selectively emitted from a light-emitting/-detecting element (31) that selectively emits a plurality of light beams different in wavelength from each other, and also return light from an optical disk (2), a first diffraction grating (45) that splits the light beam emitted from a light-emitting/-detecting element (31) into three beams including a zero-order light beam and positive and negative first-order light beams, a second diffraction grating (46) that diffracts the return light for traveling along a light path separate from that of the outgoing light, and a third diffraction grating (47) that corrects a light-path deviation by diffracting the positive first-order light beam diffracted by the second diffraction grating (46). The light-emitting/-detecting element (31) provides a focusing error signal FE by detecting the negative first-order light beam diffracted by the third diffraction element (47), and a tracking error signal by detecting return portions of the positive and negative first-order light beams from the first diffraction grating (45).

A method of transferring file of the present invention by the two simultaneous data transmissions comprises the steps of transmitting data in a forward direction starting from a first specified position to a bottom in the file, and transmitting data in a backward direction starting from a second specified position to a top in the file. And a method of transferring file in FTP of the present invention comprises the steps of establishing a control connection, establishing multiple data connection, dividing a file into segments from each arbitrary point in the file, transferring segments through each of the multiple data connections, respectively, and synthesizing file from the segments transferred through the multiple data connections.

A stable sodium percarbonate having excellent stability when incorporated into a bleaching agent composition or a detergent composition, particularly a zeolite-containing detergent composition. The stable sodium percarbonate is produced by a process which comprises a step of treating sodium percarbonate on the surface with at least one coating agent selected from the group (A) consisting of boric acids, borates and alkali metal silicates and at least one coating agent selected from the group (B) consisting of carbonates, hydrogencarbonates and sulfates, and at least one coating agent selected from the group consisting of coating agents belonging to groups (A) and (B) being present in the form of an aqueous coating slurry thereof.
摘要:
A coding apparatus is disclosed, in which coding can be achieved by simply storing, in a memory, the results of necessary coding operations including the feedback of the quantization error and reading out the data from an address of the memory specified by input data. Consequently, an encoded code can be obtained at a far higher speed than in a case where operations are performed by individual operation circuits for coding and decoding.
