Title: Character segmenting system
Inventor: KAMATA HIROSHI
IPC: G06K9/62
Filed: 1988-03-16
Abstract: PURPOSE:To segment and recognize a character with high probability by making it possible to segment a character from the whole continued character input pattern or also from the way of the pattern to recognize the character. CONSTITUTION:The title system is constituted of a continued character input pattern 10, a feature extracting part 12, a character pattern feature position storing part 14, a character collating part 16, a character segmenting part 18, and a segmented result storing part 20. A break of an image in continued characters, a loop and the feature and position of a point or the like are extracted and a character pattern having the same features and stored in a dictionary is selected and collated with the part of its corresponding character input pattern. Thereby, it is unnecessary to specially fix a character segmenting range and a character can be segmented from an optional way position of the consecutive character input pattern. Even in case of consecutive characters, a character can be segmented and recognized with high probability.

Inventor: ARIGA SEIICHI
IPC: H01L27/04
Filed: 1987-03-19
Abstract: PURPOSE:To enable a thin and high-quality oxide film to be formed on a nitride film, by establishing dry atmosphere for heeling oxidation of the nitride film while specifically determining a temperature and duration of time for performing oxidation as well as a thickness of a healing oxidation film to be formed. CONSTITUTION:After production of a nitride film 13, healing oxidation is performed within dry atmosphere. This healing oxidation should be performed at a temperature of 850-950 deg.C for 100 minutes or more so that an oxide film 14 as thin as possible ip formed on the nitride film 13. That is, by forming the healing oxidation film with a thickness of 5-10 Angstrom , a very thin and high- quality oxide film 14 can be provided on the nitride film 13. Though the oxide film 14 can be formed very thin, the thickness thereof is controllable by changing temperatures. Accordingly, by healing for a predetermined time, variance in thickness is substantially eliminated and the oxide film can be formed to have a uniform thickness.

Title: Roll coolant controller
Inventor: CHIBA MINORU
IPC: B21B27/10
Filed: 1980-05-14
Abstract: PURPOSE:To provide a roll coolant controller which is possible to restrict the loss of pumping power to the minimum, by constituting the controller so as to control the flow rate of the coolant supplied to rolling rolls correspondingly to the rolling load, that is the heat generation. CONSTITUTION:The coolant 3 is supplied to nozzles 5 through a pressure control valve 8 and a flow meter 10 and is ejected against a rolling mill 2. A motor 1 driving the rolling mill 2 detects a rolling power almost proportional to the heat generation due to the integrated rolling load, and inputs it as a rolling power signal to a digital blender 11. On the other hand, a flow meter 10 detects at this point of time the flow rate of the coolant being supplied to the nozzles 5, and inputs it as a flow rate signal to the blender 11. The blender 11 compares these two input signals; if the ratio of two signals deviates from a preset value, the blender 11 sends out a corresponding command signal to the valve 8 which is thereby actuated so as to adjust its opening in order to obtain the said preset value. Accordingly, the flow rate of the coolant supplied to the rolling mill is controlled always to a required value exactly corresponding to the heat generation, so that the power for supplying the coolant is reduced.

Filed: 1980-05-13
Abstract: PURPOSE:To collect residual toner by colors, by sticking the residual toner, whose stiking force is weakened electrically in advance while a photoreceptor drum is idling, to the magnetic brush of a developing device. CONSTITUTION:When an optical scanning system is returned at a high speed, various troubles are caused, so it is returned in a longer time than a no-picture area. In this case, the returning process makes inroads into the time of the next process, so the process of idling is provided. As a substitute for a conventional cleaning device, a discharger charger 41 is provided, and in idling the charger 41 weakens the electrostatic sticking force of residual toner on a photoreceptor drum 8 by corona discharge. For the use of yellow toner, a developing device 16 is put in operation to stick it to a sleeve 16a mechanically by slide-friction. Magneta toner or cyan toner, when used, is corrected by a device 17 or 18. Thus, the residual toner is collected by colors.

IPC: G02B5/20
Filed: 1983-04-11
Abstract: PURPOSE:To obtain a color filter having no defect at all by vapor-depositing selectively a color material to only a defective part of a color filter formed on a substrate. CONSTITUTION:A color filter 12 is formed directly on a substrate 13, and when a defect 11 exists, a positive resist film 21 is applied onto the substrate 13, and thereafter, it is prebaked. Subsequently, only one element portion (part of the defective part 11) of the color filter is exposed. After passing through a prescribed developing and rinsing process, a resist mask 31 in which a resist film does not exist on only the defective part is formed. As for this mask 31, the whole surface exposure is executed in advance in order to melt and remove it afterwards. Subsequently, a color material vapor-depositing film 41 is vapor- deposited, and the resist mask 31 is removed, by which a restored color filter 51 is obtained.
