Title: Optical mask and exposing method using the same
Inventor: HAIRI ISAMU
IPC: G03F1/76
Filed: 1989-07-10
Abstract: PURPOSE:To reduce the unnecessary thickness reduction of a photoresist film by providing a 3rd light transmission part which is not as wide as a 2nd light transmission part and transmits light for exposure in phase with the 1st light transmission part and specifying the center interval between the 1st light transmission part and 3rd light transmission part. CONSTITUTION:The optical mask is equipped with the 1st light transmission part whose width is less than lambda/(NAXM) (where lambda is the wavelength of exposure light, NA is the numerical aperture of a projection lens, and M is projection magnification), a 2nd light transmission part 2 which is narrower than the 1st light transmission part and transmits the light for exposure in opposite-phase relation with the 1st light transmission part 1, and the 3rd light transmission part 3 which extends outside the 2nd light transmission part 2 along a light shield part 6 and is narrower than the 2nd light transmission part 2 and transmits the light for exposure in phase with the 1st light transmission part 1. Then the center interval between the 1st light transmission part 1 and 3rd light transmission part 3 is set to <=1.34Xlambda/(NAXM). Therefore, the transmitted light of the light transmission parts 2 and 3 does not increases in light intensity peak on an exposed surface. Consequently, the unnecessary thinning of the photoresist film is reduced.

Title: Image collating device
Inventor: FUJISAKI AKIYOSHI
IPC: G06F9/44
Filed: 1989-07-12
Abstract: PURPOSE:To attain the inexpensive collation of images with high overall reliability and a high degree of freedom by providing plural individual coincidence deciding means and a general coincidence deciding means which decides the general coincidence with a fuzzy inference. CONSTITUTION:When the collation is carried out between each image segmented in a window set at the register side and each image segmented in a window set at the input side, the individual coincidence deciding means 50-54 decide the individual coincidence between each input image segmented in each window and each image segmented in each corresponding window in a registered image. Then a general coincidence deciding means 56 decides the general coincidence between an input image and the registered image with a fuzzy inference based on each coincidence degree of the windows set at the register and input sides respectively. Thus it is possible to omit the complicated deciding software that is so far required for addition of plural deciding elements. As a result, the inexpensive collation of images is attained with high overall reliability and with improvement of the deciding degree of freedom.

Title: Looseness eliminating method for tape in tape driver
Inventor: FUTAGAWA TOSHINOBU
IPC: B65H77/00
Filed: 1985-08-15
Abstract: PURPOSE:To eliminate the looseness of a tape, by making the outer circumferential length of each first roller differ as much as the specified value at a time in advance so as to alter both winding and delivery quantities to and from each of the these first rollers as much as the specified value at a time in spite of any variation in an outer circumferential diameter of a second roller. CONSTITUTION:Tapes 131-13n in thickness (t) are wound between first rollers 111-11n of radii r1-rn and a second roller of a radius R1 parallelly set up with each other. In this case, the condition required for each tape being moved without looseness comes to rn=r1+(r1/R1)(n-1)t. Here, each of r1, R1, (n) and (t) is a constant value to be set at the time of a design, so if these four values are set, each radius of first rollers 112-11n is set automatically. Therefore, in case of these first rollers consisting in a circular section each, it will do that these radii r2-rn are merely selected to such values that satisfy the said conditional equation. As a result, tape looseness is eliminable.

Filed: 1990-07-06
Abstract: PURPOSE:To prevent generation of tungsten carbide at the time of baking by holding sheetlike molded forms by a pair of holders arranged on both side surfaces, laminating them between the adjacent holder pair in a state for forming an interval, and baking them under the normal pressure. CONSTITUTION:A contact area with vapor is obtained on holders 2 by forming an interval between paired holders 2 adjacent to each other. Thus, decomposed product of carbonaceous substance generated by baking sheetlike molded forms 3 is passed through the holders 2, and discharged to an interval between the holder pair. Further, the interval becomes a gas vent passage, and the product is externally discharged therefrom. Thus, the carbonaceous substance is effectively removed from the forms to prevent generation of tungsten carbide in the forms. For example, when a holding body 5 for holding the forms 3 by the holders 2 is disposed in a crucible, a plurality of legs 4 are interposed between the opposed holder pair of the body 5 to isolate the pair at a predetermined interval.

Abstract: PURPOSE:To cause no strain in an activated layer and to obtain a high luminous efficiency by making a window in a semiconductor layer for narrowing the current  and by forming a heteroconductive type connection layer epitaxially so that the surface thereof is smooth by utilizing the characteristic of epitaxial growing. CONSTITUTION:An N type Inp32, an In1-xGaxAs1-yPy activated layer 33, a P type InP34  and an N type In1-x'Gax'As1-y'Py' 35 are formed epitaxially in sequence on an N type InP  substrate 31 and a part of the layer 35 is etched selectively by a liquid wherein the  ratio of H2SO4:H2O2:H2O=5:1:1. Next, by utilizing the characteristic of the epitaxial  growing, P<+> type In1-x''Gax''As1-y''Py'' 36 one to three times thicker than the layer 34 is  grown, a P side electrode AuZn 37 is prepared on the flat surface, while an N side electrode AuGeN is prepared on the substrate 31, and a window is made on the N side. According to this constitution, the absence of an insulating layer of poor thermal conductance enables excellent radiation of heat and reduces the deterioration of the element. And, since the application of proton is not used as a method for narrowing the  current, the activated layer is not damaged and the luminous efficiency is excellent.
