摘要:
Embodiments of the present invention provide a magnetic disk drive in which the error correction capability of ECC is improved without sacrificing the storage capacity. In one embodiment, a data track adopts a format structure in which no data-to-data gap area is formed in data sectors. When one of the data sectors is updated in a state in which the rotational speed of a magnetic disk does not satisfy specified conditions, a leading end area of a succeeding data sector or a trailing end area of a preceding data sector is overwritten by the data sector. If a read error occurs in the overwritten data sector, ERP steps are executed to perform read retry so that the read error is recovered by means of on-the-fly ECC or erasure correction. In the case of the erasure correction, an erasure pointer equivalent to the maximum number of overwritten bytes is set.

This invention has as its object to be able to support stream recording/playback even when information associated with a reception time of a digital stream signal is not available. Management information of a storage medium is configured to include a flag bit (PATS_SS) indicating validity/invalidity of information (PATS) associated with a reception time of a digital stream signal.

A host device is connected to at least one printer through a network. Before printing, the host device broadcasts a query on the network, selects a printer that replies to the query, and sends printer setting information to the printer. The printer includes a setting switch that can be set to different states to accept or reject the printer setting information. A printer replies to the query only if its setting switch is set to the state that accepts the printer setting information. The setting switch avoids the generation of unnecessary replies and thereby simplifies the selection of the printer, as well as protecting the printer from unwanted alteration of its settings.

A cavity plate for an ink-jet printhead includes a base material and a chamber sheet. An ink channel array constituting ink chambers is provided through the chamber sheet by a wire electric discharge machine, while an ink reservoir is formed on the base material by a wire electric discharge machine. Then, the chamber sheet and the base material are bonded to one another. Nozzles to eject ink may be created on a nozzle sheet, which is later connected to the chamber sheet. Alternatively, the nozzles may be directly provided on the chamber sheet. Thus, the cavity plate is provided having the ink chambers and the ink reservoir with high precision, without the increase in the production cost.

There is provided a condition; n.times.T.ltoreq.P.ltoreq.(n+0.4).times.T between a pulse width P of the driving voltage that is to be applied to said piezoelectric element 7 of a piezoelectric plate 6 and a time T needed for that a pressure wave of ink, which generates when the ink chamber 2 is pressurized through the piezoelectric element 7, travels through the ink chamber by a length thereof. Under the condition, each of the piezoelectric elements 7 is driven. Here, the "n" is an integral odd number (preferably, 1 or 3).

A coordinate measuring machine and the method of measuring therein wherein the instruction of the geometic shape is prevented from mistaking and the geometic shape of the workpiece is measured without interrupting the joystick operation. The measuring direction of the probe and the measured value of workpiece are taken in the data receiving part. The geometic shape calculation part calculates the errors of each geometic shape based on the measured value from the data receiving part and the formula which was input previously and represents the geometic shape such as "a straight line or circle". And, the geometic shape recognition part compares respective shape errors such as "a straight line and circle" which are calculated in geometic shape calculation part and recognizes the geometic shape having the lowest shape errors. Further, the optimal geometic shape is recognized again based on the geometic shape having the lowest recognized shape errors and the measuring direction of the probe which is input from said data receiving part. Therefore, the step for inputting the geometic shape of the workpiece by the key can be removed before measuring. Moreover, the geometic shape can be recognized in a short time, because the geometic shape of workpiece can be automatically set based on the characteristic such as "a point, straight line or circle" whenever the definite measured point of the geometic shape of the workpiece is obtained.

A fluidized type paint powder tank has a fluidizing chamber for fluidizing paint powder and a storage chamber into which the paint powder in the fluidizing chamber is fed to keep it still. There is also provided a paint supply device for an electrostatic painting apparatus that includes a paint tank for containing paint powder and a painting gun coupled to the paint tank through an injector and a hose. The device includes a discharge member for discharging the paint powder from the paint tank and a hopper for receiving the paint powder discharged by the discharge member. A screw feeder is provided under the hopper. With this arrangement, the paint powder supplied at a uniform rate by the screw feeder is fed into the injector.

The superconducting structure for magnetic shielding according to the present invention comprises at least two layers of a superconducting layer and a substrate. This superconducting structure for magnetic shielding can be formed in a plate-like shape or a cylindrical shape. When the structure is prepared in three-layers by providing an intermediate layer between the superconducting layer and the substrate, the three-layered structure has improved superconducting properties. When a protective layer is provided on the superconducting layer to protect the layer, the resulting structure has improved thermal shock resistance. The intermediate layer preferably consists of a ceramic or a noble metal and the ceramic preferably consists of a glass.
