摘要:
A synthetic filament-reinforced polymer material sheet having a very small thickness of 0.25 mm or less and a large specific tensile strength of 3.4.times.10.sup.6 cm or more is composed of a reinforcing sheet in which a number of straightened individual synthetic polymer filaments are arranged in parallel to each other and are spaced from each other at an average interval not larger than the average thickness of the filaments, and which has a width W anmd a thickness T satisfying the relationship W/T.gtoreq.40 and a coefficient of variation of thickness of 30% or less, and a polymer material impregnated in the spaces between the individual filaments.
摘要:
A cut pile fabric such as a velvet composed of a synthetic fiber pile having deep color shade and smooth touch on its pile surface, the piles thereof having non-mushroom shaped cut ends at their tip portions, defined by the equation d.sub.1 /d.sub.2 .ltoreq.1.3, where d.sub.1 is the maximum diameter of the tip portion and d.sub.2 is a diameter of the remaining portion of the piles. The pile fabric is obtained by utilizing, as a pile yarn, a synthetic yarn having a breakage strength of less than 2.8 g/De, a primary yielding strength of more than 1.2 g/De, a breakage elongation of less than 50%, and a primary yielding elongation of less than 10%. Such synthetic yarn can advantageously be prepared by a crystallization drawing process.
摘要:
A method, apparatus and computer-readable recording medium are disclosed, for recording information in an information recording medium. The method includes a first step of outputting, in response to an initialization request for initializing the information recording medium, termination information indicative of termination of the initialization before the initialization starts, and a second step of starting the initialization at a predetermined timing after the output of the termination information. In this procedure, it is possible to start to record data in a blank disc sooner than in conventional methods.
摘要:
An imaging apparatus includes an emission device for illuminating a subject, a preliminary emission control device for controlling preliminary emission before photographing, a photometry device for measuring a reflected light volume from the subject in the preliminary emission so as to obtain a photometric result, and a main emission control device for controlling main emission when photographing, the main emission control device has a first emission control for conducting emission by adjusting emission volume by using the photometric result, and a second emission control for conducting emission until the reflected light volume from the subject reaches a predetermined volume, the main emission control device conducts an emission control by either the first emission control or the second emission control according to the photometric result.
摘要:
On an information recording medium, a recording area is divided in a plurality of data areas, and data is recorded on each of the data areas. In response to a request for obtaining data management information concerning a recording of the data recorded on each of the data areas, a plurality of predetermined data areas among the foregoing data areas are regarded as a predetermined pseudo area, and the data management information including information concerning the predetermined pseudo area is obtained.

摘要:
A disk-shaped rewritable information recording medium having at a first recording layer and a second recording layer is disclosed. The information recording medium includes a first data area situated in the first recording layer, the first data area having a plurality of addresses allocated thereto, the plural addresses continuously increasing in a first direction, a second data area situated in the second recording layer, the second data area having a plurality of addresses allocated thereto, the plural addresses continuously increasing in a second direction opposite to the first direction, and a management information area having an area for recording end recorded area information thereto, the end recorded area information including information for identifying an area in the second data area having data that corresponds to an end position of the second data area.
摘要:
A data storage apparatus, which can format a recording medium in the background, that verifies data written in a designated region of the recording medium if the designated region has not yet been certified in the background, and writes the data in an alterative region of the recording medium if the designated region is found defective. Since the data storage apparatus either certifies the designated region of the recording medium or verifies the data written in the designated region, the data storage apparatus can enhance the reliability of the data written in the recording medium, but the data storage apparatus does not waste time by verifying the designated region of the recording medium two times or more.
摘要:
An apparatus for processing information is disclosed. The apparatus requests for recording of user data into an information-recording apparatus for recording in an information-recording medium having multiple recording layers, each of the layers having a data area for recording the user data. The medium has a first recording layer to be a reference for determining a position of the data area in each of the recording layers, and a second recording layer excluding the first recording layer.
