Title: Pattern formation by electron beam exposing device
Inventor: NOMA AKIRA
IPC: H01L21/027
Filed: 1979-08-21
Abstract: PURPOSE:To simply measure the degree of accuracy of a main pattern and an exposing device by a method wherein a pair of auxiliary patterns are drawn front and after main pattern on the same region and positional relations of the auxiliary patterns are detected. CONSTITUTION:A glass substrate 21, on which a Cr film and an electron beam resist film were successively formed, is fixed on a driving stage of an electron beam exposing device. The auxiliary patterns 41 are drawn on regions 32-35, where auxiliary patterns are expected to be formed, located at the four corners of the substrate 21. Then, prescribed main patterns which are actually required are drawn on an expected main pattern forming region 31. After drawing, a pattern 41 and a mating auxiliary pattern are superposed on regions 32-35 successively. Then, developing and etching processes are performed and patterns are formed. The patterns 41, 43 and 42, 44 are established in advance in such way that (a) and (b) alone are deviated and by detecting this deviation of position, the measurement of accuracy of the main pattern can be performed.

Title: Board carrier device and aligner using the same
Inventor: MARUMO KOJI
IPC: B65G49/07
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To avoid a trouble caused by idle carrying of a carrier hand.

Title: Track tracing device
Inventor: IRIE MITSURU
IPC: G11B7/09
Filed: 1987-05-01
Abstract: PURPOSE:To eliminate track offset and to facilitate the adjustment of a detector, by setting the width of a photodetecting part in a direction perpendicular to a track almost equal to that of an interaction area on which the diffracted light of a reflected beam of light is superposed in the direction perpendicular to the track. CONSTITUTION:When track deviation detecting beams of light exist on the photodetecting parts 1a and 1b, the displacement of the interaction areas 4a and 4b are generated. Since the photodetecting parts 1a and 1b are arranged in the centers of the areas 4a and 4b in such a way that the width (u) of them are narrowed than the width in which the double of the maximum travel quantity of the displacement is subtracted from the width (x) of the areas 4a and 4b, small amount of unbalance occurs in a photoreceiving quantity due to the inclination of a recording medium or the travel of an objective lens in the direction perpendicular to the track. Therefore, a stable track deviation signal can be obtained. Also, even when deviation in a direction in parallel with the track occurs, since the width (v) on the other sides of the photodetecting parts 1a and 1b are larger the width (y) of the areas 4a and 4b, no unbalancing occurs in the photoreceiving quantity. In such a way, it is possible to obtain a stable deviation signal for the deviation, and to facilitate the adjustment of an optical detector.

Title: Underground continuous wall
Inventor: KURODA MASANOBU
IPC: E02D5/18
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To rationalize execution and reduce the execution cost by dividing an underground continuous wall into three portions of a top section, an intermediate section, and the deepest section in the height direction, and setting the concrete strength of the top section and the deepest section relatively lower than the concrete strength of the intermediate section. SOLUTION: An underground continuous wall W is divided into three portions of a top section W1, an intermediate section W2, and the deepest section W3 in the height direction. The intermediate section W2 and the top section W1 function as an earth retaining wall, and the deepest section W3 functions as an impervious wall. The concrete strength of the underground continuous wall W is set relatively lower at the deepest section W3 and the top section W1 than at the intermediate section W2. The low-strength range is expanded as compared with the conventional underground continuous wall having the uniform concrete strength over the whole height or having the low strength only at the prescribed depth or deeper. This underground continuous wall W is structurally reasonable, the execution cost can be reduced, and it can be made sufficiently economical.
