Abstract: PURPOSE:To avoid the deterioration of the disk availability by using a means which manages the files on a disk and another means which stores and manages the fixed number of files to control the erasion of files and therefore recovering the files even if erased by mistake. CONSTITUTION:A film managing block 6 that is not presently registered yet is obtained in a file register mode with reference to the valid//invalid discriminating information 3 of the directory information 2 stored in a directory managing table 1. Then a disk block managing table 8 is retrieved and an idle block is secured on a disk by an amount enough to store files. Thus the files are stored and the file managing information on the file names, attributes, etc., are stored in the block 6 of the stored file. Then a disk block number 7 of the disk block forming a file 9 is stored in the block 6. Thus the disk block occupied by the file 9 is managed by the number 7. Furthermore a file access count 13 is set at 1 for the information 2 and the information 3 is defined as 'valid'.

Title: Method and apparatus for forming or renewing horizontal marking on road and horizontal marking formed by said method
Inventor: MOOZESU BORAKU
IPC: E01C23/16
Filed: 1988-02-23
Abstract: During the laying of a marking line with the aid of at least one paint spray gun (2), profile particles (5) are introduced by means of a profile particle dispenser (4) into the marking composition (3) and thereby enveloped all round by the latter. The dimension of the profile particles (5), which are preferably reflective beads, is greater than the layer thickness of the bare painted line, so that profile elevations are formed. Subsequently, reflective beads (8) which also adhere to the profile elevations are scattered onto this profiled painted line (6), which beads thus ensure a good night visibility in wet conditions and when a water film is present, from which they project. The profile particles (5) can either be directly introduced into the jet of paints emerging from the paint spray gun (2) or, subsequent to the application of a painted line, be scattered thereon and then completely covered with marking composition by means of renewed spraying of a thin film of paint.

IPC: C03B11/08
Filed: 1988-02-25
Abstract: PURPOSE:To obtain a mold member for forming an optical element, easily producible in high precision, causing little lowering of the accuracy in press- forming and having long life, by using a mold member for forming an optical element wherein at least the forming surface of a mold matrix is covered with WN. CONSTITUTION:A matrix material composed of e.g. a refractory metal or sintered SiC is used as a mold matrix 30 and the material is shaped to a desired outer shape by cutting, grinding, polishing, etc., and especially the forming surface is finished to a desired surface accuracy. A WN layer 31 is applied to the surface of the matrix material 30 by a physical vapor deposition process (PVD process) such as sputtering or ion plating or a chemical vapor deposition process (CVD process) such as plasma CVD process. Since the WN layer 31 has high oxidation resistance even at a high temperature, it has low adhesivity to molten glass and good mold-releasing property. Accordingly, optical elements having good accuracy can be produced even with a repeatedly used mold.

IPC: H02G1/12
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To easily obtain a surface roughness without mirror finishing or smoothing, by providing a blade with a slant edge for forming a tapered section of a specified size and an R-edge for cutting an insulator layer which is continuously formed with the slant edge at the end of it. SOLUTION: A cutting blade 4 for an external semiconductive layer is fed in the direction F as shown by an arrow in the Figure, while revolving around a cable 1 to cut off an external semiconductor layer 3 and, after that, it is stopped and is allowed to go outside to form a tapered section. The cutting blade 4 is provided with a slant edge 50 for forming a tapered section of the size L longer than the slant side length K of the tapered section. Continuously with the slant edge 50, an R-edge 49 is formed at the end of the slant edge 50. As a result, an insulator layer 8 is smoothly cut by the R-edge 49 and smoothing or mirror finishing can be eliminated. Since the tapered section can be formed immediately by the slant edge 50 for forming a taper, a simple automatic cutting device without a complicated feeding mechanism for forming a taper can be used.
