Title: Method for taking in alignment mark
Inventor: ARAI HIROYUKI
IPC: B41M1/34
Filed: 1989-08-30
Abstract: PURPOSE:To sharply confirm an alignment mark up to the end part thereof by strong reflected light by forming the alignment mark to a transparent substrate and providing a reflecting surface to the transparent substrate under the alignment mark and observing the reflected light from the reflecting surface by a CCD camera. CONSTITUTION:Red image lines 5 and two alignment marks 4 are simultaneously printed on the surface part of a transparent substrate 1 in the first printing. When lights having proper intensity are emitted to the opposed alignment marks 4 on the respective sides of two CCD cameras 3, said lights are absorbed by red ink 6 at a place where the ink 6 is printed or the lights returned by the irregular reflection generated at the uneven parts of the surfaces of said marks are little and, therefore, an image becomes dark but, at the places of the alignment marks 4 where the red ink 6 is not printed, strong lights are reflected and returned from the reflecting surfaces under the alignment marks 4 and, therefore, the alignment marks 4 are sharply confirmed up to the boundary parts thereof. Therefore, when the observed images due to the CCD cameras are decomposed into fine pixels to be analyzed, the presice positions of said images can be grasped.

Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To protect a slope from public hazards until vegetation grow up, by using a netted material for greening, in which a vegetation sheet is integrally formed in the netted material woven with warp and weft threads made of a completely biodegradable plastic and a natural fiber. SOLUTION: Warp threads 12 and weft threads 14 are arranged at every specified distance and a netted material 10 is woven by plain weave, intertwined weave, or Raschel weave. When the netted material 10 is woven or knitted, a vegetation sheet 16 in which vegetation seeds, fertirizer, soil conditioners, etc., are held in a nonwoven fabric or the like is integrally formed and heat- sealed thereafter to obtain the netted material for greening. When laying the netted material for greening on a slope, a natural fiber material having smaller elongation is arranged in the relatively tensile direction and a completely biodegradable plastic having a higher strength is used in the other direction. This netted material for greening can be made at a low cost and it can prevent the slope ground from errosion and retain the strength until vegetation materials grow up and finally turn to earth.  And hence, it can be protected from public hazards.

Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To widen the working temperature and improve the displacement characteristic when it is repeatedly used for a long period of time in the application to motor vehicles by specifying the proportion of the tetragonal crystals in the crystalline phase of the PZT piezoelectric porcelain composition. SOLUTION: As raw materials, PbO, ZrO2 and other oxides giving the third components are mixed in a proportion that the objective composition is given, calcinated, molded and fired to give a piezoelectric element. The ratio of the rhombohedral crystals to the tetragonal crystals in the composition can be varied by this component ratio. When the proportion of the tetragonal crystals is set to 83-95%, the piezoelectric element produced from this composition shows a large displacement, small current leak and high stability to the temperature change. Additionally, the actuator produced from the piezoelectric element shows small reduction in the displacement and high durability, even when it is repetitively driven.

Title: Optical head
Inventor: ANDO HIDEO
IPC: G11B7/125
Filed: 1989-08-31
Abstract: PURPOSE:To miniaturize and simplify the optical system by providing a non- polarized ordinary ray splitting layer, transmitting the light from an information storage medium therethrough, separating the light beam to an ordinary ray and an extraordinary ray by a prism member, and detecting these rays. CONSTITUTION:The light beam from a light source is directed to a detecting optical system 14 as the plane of the polarization thereof inclines when a tracking guide formed on the information storage medium 12 is extended in a direction X. The optical element 14 has two boundary surfaces 14A, 14B, one 14A of which is made of an optically anisotropic medium. The boundary surface 14B is made of an optically isotropic medium and the incident light beam on the optical element 14 is partly reflected by a light reflecting layer 10. The remaining beam is transmitted therethrough. The light intensity of the light beam of the central part, where the light intensity is large, introduced into the detecting element 14 is detected by a photodetector 16 existing on the side face of the prism member 4. The member 4 separates the light beam to the ordinary ray and the extraordinary ray at this time. Since the angle of sepn. can be increased by setting the inclination of the boundary surfaces 14A, 14B, the optical system can be simplified and miniaturized.

Title: Method and equipment for detecting pattern and projection aligner employing the same
Inventor: OSHIDA YOSHITADA
IPC: G03F9/00
Filed: 1993-09-10
Abstract: PURPOSE:To detect the position, width, interval, etc., of a pattern formed on a wafer correctly by varying the spectroscopic illumination intensity characteristics of light emitted from a light source depending on the information relating to the layer structure and the material of an object to be detected and then detecting the pattern image of the object illuminated at a spectroscopic illumination intensity being obtained. CONSTITUTION:Light projected from an illumination light source 11 passes through a spectroscopic intensity/directivity adjusting illumination means 12 to produce an optimal spectroscopic illumination distribution with the light of each wavelength exhibiting a desired directivity. The light then enters into a detection system 10x where the lights having wavelength in the range of lambda2-lambda3 being split through a wavelength selective beam splitter 106 are detected by a spectroscopic transmittance/ numerical aperture regulating/detecting means 13 with an optimal numerical aperture for each wavelength. Each characteristic of illumination light regulated through the means 12, 13 has different optimal value depending on the structure of wafer pattern or the properties of material of the object to be detected. The optimal values are calculated off-line and inputted on an input terminal 22.
