IPC: G06K9/20
Filed: 1989-09-20
Abstract: PURPOSE:To accurately read even an impressed character having ink blurred based on a trace of impression by irradiating the contact line between a ruggedness investigating member and an object material with light from one side and photographing the leaked optical image on the line leaked to the other side. CONSTITUTION:A horizontal lower edge 5a of a ruggedness investigating member 5 is linearly closely brought into contact with the surface of a read object material 1 except gaps corresponding to recessed parts 2a of a rugged pattern 2. A carriage 3 is driven to relatively move the ruggedness investigating member 5 and the read object material 1 in the direction of an arrow 4, and image pickup of an image pickup device is repeated. A video signal which has a level corresponding to the leaked light on a close line 6 is obtained from the image pickup device 8. The video signal outputted from the image pickup device 8 in time series passes an A/D converter 9a and is stored in a picture memory 9b, and the reproduced rugged pattern 2 is read in a character recognition processing part 10 by the pattern recognition method or the like to recognize a pertinent character. Thus, an impressed character or the like is read with a high precision regardless of blur of ink or the like.

Filed: 1983-12-27
Abstract: PURPOSE:To always automatically adjust the quantity of overlap of a paper feed roller and a separation roller to a value appropriate for paper feed, by performing the feedback control of the capability of separating sheets of paper one by one, on the basis of mutually contradictory data 'Abnormal overlaid conveyance' and 'Paper feed impossible'. CONSTITUTION:A separation roller 7 is supported movably relative to a paper feed roller 6. At every feed action for a sheet of paper W, mutually contradictory data 'Abnormal overlaid conveyance' and 'Paper feed impossible', which are given by a pair of light emission diode 33 and light reception diode 34 and another pair of light emission diode 37 and light reception diode 38, respectively, are smapled for feedback to control the drive of a pulse motor 23 to adjust the position of the separation roller 7. The quantity of overlap of the paper feed roller 6 and the separation roller 7 is thus always automatically adjusted to the optimum to separate the sheet of paper W into the best state to feed it. This constitution enables the sure feed of the paper independently of the surface materials of the rollers 6, 7 and the change in the coefficient of friction between them due to the temperature change.

Title: Inspecting device for soldering appearance
Inventor: KAWATO SHINJIRO
IPC: B23K1/00
Filed: 1989-09-20
Abstract: PURPOSE:To decide whether a soldering state is normal or abnormal stably even if a solvent is left at a soldered part by lighting the soldered part with infrared light when an image of the soldered part is picked up by a television camera. CONSTITUTION:When the soldered part including leads 4 of an IC 3 mounted and soldered on a printed wiring board is positioned in the visual field of the television camera (CCD camera with good sensitivity even to infrared light) 1, an infrared-light source 2 irradiates the soldered part with the infrared illumination light. The image picked up by the camera 1 is stored in an image memory 6. When this image is picked up under the illumination with invisible infrared light the remaining solvent at the soldered part is obtained with better contrast than that is lighted with visible light. Then an arithmetic decision part 7 sets a frame for inspection between leads 4 in the image to decide solder bridge abnormality when there is a part which is brighter than a specific threshold value in the frame and decides that the soldered part is normal when there is no part brighter than the threshold value.

Title: Preparation of heat-sensitive recording medium
Inventor: OSAWA HARUHIKO
IPC: B41M5/40
Filed: 1993-09-06
Abstract: PURPOSE:To provide a method for preparation of a heat-sensitive recording medium with good adhesiveness and durability of a printing layer. CONSTITUTION:A protective layer 18 on a heat-sensitive recording layer 14 is formed by coating with a material contg. an ultraviolet curable resin and it is cured weakly by means of ultraviolet irradion not so as to generate blocking. After a printing layer 20 and a printing protective layer 22 are formed by performing offset printing with an ink contg. an ultraviolet curable resin, ultraviolet irradiation is performed again to cure completely the protective layer 18 with the printing layer 20 and the printing protective layer 22. As the protective layer 18 is not completely cured when the printing layer 20 is formed, adhesiveness of the printing layer 20 is good. Furthermore, durability is also excellent by complete curing thereafter.

Title: Ferrous sintered compact, powder for manufacture of ferrous sintered compact, and manufacture of ferrous sintered compact
Inventor: HISADA TAKEO
IPC: C22C38/00
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a ferrous sintered compact hardly causing red brittleness and capable of attaining uniform superior lubricating property. SOLUTION: By sintering a powder composed essentially of Fe and containing 1-4 wt.% S component and 18-30 wt.% Mo component, a sintered compact structure in which S-enriched phases are dispersedly formed can be easily obtained. By achieving the ferrous sintered compact structure in which S-enriched phases are dispersedly formed, uniform and superior lubricating property can be attained on application of the sintered compact to bearing, machine sliding parts, etc. Because, unlike FeS in a cast material, the S-enriched phases 52 do not precipitate in netlike (reticular) form but exist in the form of dispersion, the problem of red brittleness is hardly brought about when hot working is further applied to the sintered compact. Further, as an alloy composition, a composition containing 1-4 wt.% S component and 18-30 wt.% Mo component and having relatively low S content is selected.  By this procedure, the formation of the S-enriched phases composed essentially of Mo sulfides excellent in solid lubricity can be accelerated, and the ferrous sintered compact having superior lubricating property can be obtained.

Title: End surface light emitting type thin film electroluminescence element
Inventor: ESAKI SANPEI
IPC: H05B33/22
Filed: 1991-09-25
Abstract: PURPOSE:To realize high energy radiation by disposing dielectric layers each having a predetermined refraction factor while adopting a refraction factor of a light emitting layer as a reference. CONSTITUTION:Dielectric layers 3, 5 are formed on both surfaces of a light emitting layer 4. Each refraction factor of the layers 3, 5 is equal to that of the layer 4 on the side adjacent to the layer 4 while it is smaller than that of the layer 4 as the layers 3, 5 are separated from the layer 4. A part of light emitting energy from the layer 4 is input into the layer 5 and the like according to the reduced refraction factor distribution. The incident light is continuously refracted toward the wave guiding direction, to be input into the layer 4 again, where it moves straight. And then, the light is input into the layer 3 and the like on the opposite side, and is refracted in the same manner. Consequently, it is possible to obtain an end surface light emitting type thin film electroluminescence element capable of high energy radiation.

Filed: 1990-09-18
Abstract: PURPOSE: To obtain a thin-film transistor(TFT) having a gate insulating structure which does not receive disadvantage at the time of deposition of a material layer by providing the surface of a first silicon layer with a second amorphous silicon layer subjected to a doping treatment so as to have a conduction type and patterning and forming a second silicon layer so as to have a drain region and source region. CONSTITUTION: The layer 38' of the amorphous silicon (a-Si) is deposited on an SiN layer 56 by plasma reinforced chemical vapor deposition PECVD, by which the second layer 40' consisting of a semiconductor material, more preferably a-Si subjected to the doping treatment so as to have N+ electric conductivity is deposited on the first a-Si layer 38'. Part of the a-Si 40' is removed from the channel region of an island structure with electrodes 26' and 28' as a mask, by which an FET element having the source region 40'a and drain region 40'b is formed. The PECVD method enables the deposition of multiple layers without substantially break vacuum and is capable of forming boundary which is not substantially affected by contaminants, such as oxygen and carbon, between the layers. As a result, the TFT having a gate insulator structure possessing high dielectric strength is obtd.

Abstract: PURPOSE:To obtain high coercive force by disposing the layer of a metal which expands in volume when solidified as an underlying layer on a substrate. CONSTITUTION:An underlying layer 2 consisting of a metal which expands in volume when solidified, for example, Bi, Ga, Sb or the alloy of said metals is deposited by evaporation to, for example, 30-300Angstrom  thickness on a high polymer film of a non-magnetic substrate 1 and a thin metallic film 3 consisting of Co, Fe, Ni or the alloy thereof is deposited by evaporation on said layer to 50- 1,000Angstrom  thickness. The substrate temp. in the stage of vapor deposition is selected at a low temp., for example, an ordinary temp. below 80 deg.C. The layer is subjected to an annealing treatment, i.e., heat treatment after vapor deposition. The heat treatment is accomplished at >=80 deg.C and thereafter the substrate is allowed to cool. Since the vapor deposition of the layer 2 and the film 3 is carried out at the low tepm., for example, about ordinary temp., generation of a deformation such as ''wrinkle'' in the substrate 1 by heating and the decrease in the magnetic characteristic owing to a decrease in the degree of vacuum occuring in degassing and dehydration are averted. The high coercive force is obtd. in the final by performing the heat treatment after the vapor deposition.
