Title: Projection aligner
Inventor: TANITSU OSAMU
IPC: H01L21/027
Filed: 1995-02-23
Abstract: PURPOSE: To highly accurately measure reflectance of a photosensitive substrate even to exposure light in an ultraviolet region by a method wherein a reflecting member having lower reflectance than that of the substrate is equipped with an optical member having at least one smooth face for reflecting the exposure light. CONSTITUTION: A high reflection member 20 and a low reflection member 100 are provided on a wafer stage WS. The low reflection member 100 has lower reflectance than that of a wafer W, and a surface of a glass plate 100 being the low reflection member is a non-coated smooth face ground with good plane accuracy. Only surface-reflected light on the non-coated smooth face is received via a projection optical system 14 or the like by a photoelectric detector 41. The photoelectric detector 41 sequentially outputs the photoelectric outputs of reflected light from respective exposure regions of the wafer W to exposure light onto a control system 42.  The control system 42 calculates reflectance of the wafer W by a predetermined equation based on pre-measured photoelectric outputs, reflectance and the photoelectric outputs from the wafer W with respect to the reflection light which have been sequentially detected.

Title: Rule print system for dot impact printer
Inventor: MATSUO YOSHIKI
IPC: B41J29/26
Filed: 1989-03-13
Abstract: PURPOSE:To lengthen service life of print head and to prevent shifted printing by switching the lateral rule print pattern every time when lateral rule print is requested then correcting paper feed accompanied to line feed by an amount corresponding to the positional shift of rule. CONSTITUTION:A plurality of print patterns having rule position shifted by m/p pin longitudinally from an identical rule, where (m) is the least common multiple of the pitch (p) of print head pin and minimum paper feed pitch (g), are prepared as rule print patterns including lateral rules. The lateral rule print pattern is switched for every request of lateral rule print and paper feed accompanied to line feed is corrected by an amount corresponding to the positional shift of rule then printing is carried out. By such arrangement, print dots do not concentrate to a specific print head pin and positional shift of paper due to positional shift of lateral rule can be prevented through correction of paper feed.

Filed: 1990-03-12
Abstract: PURPOSE:To produce a conductive electrode pattern with high density and low cost by employing an ink basically composed of resinated metallic solution and UV resin and forming a high density electrode pattern directly through pattern printing. CONSTITUTION:An ink basically composed of resinated metallic solution and UV resin is fed through a rubber roller to recesses in a lithgraph and transferred onto a transfer blanket thence transferred, in pattern, onto an object to be transferred, i.e., an insulating substrate. The insulating substrate is then irradiated with UV and dried, coated with the ink again and baked, thus forming a conductive pattern electrode of only metal through thermal decomposition. Consequently, a highly dense electrode pattern can be formed directly through pattern printing and the accuracy of line edge can be improved even if the conductive film is made thick. According to the method, a highly dense electrode can be obtained with low cost.

Abstract: PROBLEM TO BE SOLVED: To prevent the double input of an object by forming a prescribed mark on the image to be inputted in an optional area which is designated by an operator on an input object. SOLUTION: A business form 1 is carried on a carrier path 3 in the paper feeding direction 2 and then passes through an optical reading part 4 where the opponents having red wavelengths are eliminated from the ruled lines, characters, etc., and the image information is fetched by a light source system 5 including a red light source, for example. Meanwhile, the components having blue wavelengths are eliminated from the ruled lines, characters, etc., and the image information is fetched by a light source system 6 including a blue light source. Thus, the data which are read by at least one or more optical systems are expanded on a memory of every image buffer 7 as video signals.  Then the read designated characters are recognized by a character recognition program based on the image information stored in the buffer 7, and the form 1 passes through a react print part 8 where a read print record 9 is printed on the form 1. Thus, the double input of an object is prevented.
