摘要:
A transparent measuring device is disclosed. The transparent measuring device includes a planar structure formed from a sheet of transparent material having a top surface and a bottom surface and at least one raised rib formed of a transparent material on the top surface of the planar structure such that incident light is reflected/refracted on the raised rib to provide a visual graduation. The raised ribs include a top surface that may be colored such that the raised rib forms a dual-line graduation.

The invention relates to a position indicator for indicating the relative position of two components which can be displaced in relation to each other. A first indicator pattern is applied to a first of the two components in a fixed manner, and a second indicator pattern is applied to a second of the two components in a fixed manner. The first indicator pattern extends in an extension direction over a first length L1 and consists of a number N1 of essentially identical first partial patterns which periodically repeat in the extension direction. The second indicator pattern extends in an extension direction over a second length L2 and consists of a number N2 of essentially identical second partial patterns which periodically repeat in the extension direction. According to the invention, the following equations hold true: L2=L1*(1±1/N1) and N2=N1/n or L2=L1 and N2=N1/n±1. The invention is characterised in that the first and/or second partial patterns have other indicator characteristics, enabling the relative position to be read more accurately, according to the accuracy of a vernier scale with an (N1/n)-1 to N1/n graduation.
摘要:
A pressure-sensitive adhesive sheet comprising a plastic sheet (1) having on one surface thereof a pressure-sensitive adhesive layer (3), wherein the plastic sheet (1) has on at least one surface thereof a print layer (2) having a thickness of 40 to 1,000 µm and containing 30 to 90% by weight based on the total weight of the print layer (2) of an X-ray absorbing metal. The print pattern may be scales, grid lines, numbers, etc. singly or in combination. Information on individual subject or scales or grid lines pattern may be copied in a radiograph having an image of the inside of the subject body. This enables surgeons to determine the size of the inside of the subject body or position of target organ with ease.

A thimble 61 formed with graduations 65 and numerals 67 on the outer circumference thereof at predetermined intervals is molded by double-color molding using two kinds of resin 62, 63 with different colors. After a molding product having the graduations 65 protruding outwardly on the outer circumference of a base tube 64 is formed of the resin 62, an outer skin 66 covering the outside of the base tube 64 except for the graduations 65 is formed of the resin 63. Thereafter, the numerals 67 is formed on the outer skin 66 by means of laser marking. Similarly, an outer sleeve is formed with graduations and numerals on the outer circumferential surface along the axial direction at predetermined intervals.

The apparatus has a scale (10) positioned to be read by a read head (20). The scale (10) has marks (12) defined by first surfaces (40) lying at an angle (E) to second surfaces (50) defining spaces (13) between the marks (12) so that, on illumination of the scale by rays (40A, 50A), the rays (40A) falling on the marks (12) are reflected into the read head (20) while the rays (50A) falling on the spaces (13) are reflected away from the read head (20). The arrangement provides improved contrast between the marks and the spaces.
摘要:
The scale is a flexible tape comprising a substrate (111) of spring steel and a surface layer (112) of copper, the surface layer containing a scale profile (109) defining marks and spaces of the scale. The profile (109) is produced by rolling a blank (107) with an appropriately profiled roller (101).

Measuring tapes are printed by means of an ink jet printer 32, 34. The tape is printed at constant tension as it passes over a wheel 16, with drives 14, 18 before and after this wheel 16 controlled to maintain constant tension. Means 36, 38, 40 to monitor motion of the strip contacts or observes the face which receives print.
