Title: Measuring method of frictional resistance
Inventor: KIKUCHI OSAMU
IPC: B63B71/20
Filed: 1984-03-23
Abstract: PURPOSE:To enable the correspondence to the state of an indented surface of the bottom of an actual vessel, by using a test piece given a surface roughness corresponding to the surface of the bottom of the vessel by a spray material or an indented pattern form material so as to measure a frictional resistance which is used as a reference for calculating the frictional resistance of the surface of the bottom of the vessel in the water. CONSTITUTION:A test piece is formed by a method wherein a surface roughness corresponding to that of the surface of the bottom of a vessel is given to the surface of a base material for measuring a frictional resistance by a spray material containing a binder and aggregate, or an indented pattern form material formed on a roller pattern coat material. This idented pattern form material is formed as a surface layer on the surface of the base material by processes of coating, drying, etc., and by using the test piece formed in this way, the frictional resistance in the water is measured. By measuring the frictional resistance beforehand with respect to a number of test piece corresponding to various supposed roughness forms and by keeping measured values in storage as data, the frictional resistance can be calculated thereafter only by invertigating the roughness form of an actual vessel and collating the result with the data.

Title: Chemiluminescence gas analyzer
Inventor: KOZAKURA MASARU
IPC: G01N21/76
Filed: 1993-03-17
Abstract: PURPOSE:To ensure stable production volume of ozone by returning a part of produced ozone to an air supply line, converting NO contained in the air into NO2, absorbing NO2 by means of an absorbent and removing. CONSTITUTION:O3 produced in an ozone generator 3 (through silent discharge in oxygen or irradiation with ultraviolet rays) is partially returned to an air supply line through a return line. Trace NO contained in the air is oxidized in a buffer tank 8 to produce NO2. The NO2 is absorbed by a filler (absorbent) column 9 at the next stage and removed. Consequently, O3 can be fed stably to a luminescent reaction cell. Tricobalt tetraoxide (Co3O4) having high NO2 absorption power and O3 decomposition power or zeolite carrying NiO or Fe2O3 is preferably employed as the absorbent while taking account of the fact that excess O3, which did not contribute to oxidation of NO, causes corrosion of a pump 10.

Filed: 1988-03-10
Abstract: PURPOSE:To obtain a mat having ideal hardness and elasticity and rich in hygroscopicity, by mixing a pulp material with a clipped fiber and applying dehydrating press processing to the resulting mixture to form a plate-shaped body. CONSTITUTION:At first, fibrous cellulose is mixed with slurry like papermaking pulp mixed with a solution (water) in a ratio of 1:1 and a colorant is added to the resulting mixture under stirring. After uniform mixing, the slurry like mixture is dehydrated by a filter press while the dehydrated cake is received in a press mold to be compressed to a plate shape by a hot press. For example, when this compression processing is performed so as to be divided into plural times to compress the cake to 10mm in primary processing and to 5mm in secondary processing, texture becomes dense and a high quality product is obtained. The ratio of the papermaking pulp and the clipped fiber is appropriately altered corresponding to the kind of fibrous cellulose becoming a raw material and, when the water content of the papermaking pulp is low, the dehydration process by the filter press can be omitted.

Title: Automatic data classification assisting device
Inventor: MORISHITA TARO
IPC: G06F17/30
Filed: 1989-03-13
Abstract: PURPOSE:To eliminate restrictions due to the difference of an object by inputting pieces of information on the classification of a root level and the attribute of input data interactively and generating an intermediate class for input data classification. CONSTITUTION:A target class name and its attribute are inputted by an input means 1, then data on the target class and attribute information regarding the data are inputted, one after another, according to questions and answers. Every time data is inputted, a classification tree generation assisting means 4 and a classification specifying means 8 classifies the input data while generating a necessary subclass. If the user does not satisfy the classification result or requires another piece of classification information, an auxiliary classification showing means 6 offers effective information and an editing means 6 corrects or modifies the classification result. Thus, while the concept for the classification of the data is inputted interactively, a classification tree (rule) and the classification result are found at the same time and the classification rule itself is generated, so there are not the restrictions due to the difference of the object.

Filed: 1979-05-14
Abstract: PURPOSE:To prevent the discharge breakdown, to reduce the size of deflecting electrodes and to heighten a voltage therefor in an electrified quantity control type ink jet printer, by providing a unit to detect ink adhering to the deflecting electrode to control the deflecting voltage. CONSTITUTION:A light emitter 22 and a light receiver 23 are provided near the top of a deflecting electrode 6b so that the emitter and the receiver are located outside both the ends of the deflecting electrode. Since ink 21 which has adhered to the deflecting electrode 6b because of abnormal ejection due to the clogging of an orifice 2 or the like intercepts light transmitted from the light emitter 22, the ink is detected in terms of the change in the electrical current of the light receiver 23. When the adhering ink 21 is detected, a control circuit 25 is put in operation to control a section 26 to regulate a deflecting voltage applied to the deflecting electrode. Discharge breakdown can thus be prevented without lengthening the deflecting electrode or increasing the distance between the electrodes.

Title: Form detector
Inventor: NAGAMINE KEIJI
IPC: G06T7/60
Filed: 1988-03-14
Abstract: PURPOSE:To obtain a light cutting line containing no dead angle even to a complicated subject via a single image detector by setting two sheets of reflectors and two optical path selectors or two sheets of reflectors and two beam splitters at four apex position of a parallelogram respectively and keeping the coincidence up to the image detector between the optical paths for the reflected beams sent from an object to be measured in two directions. CONSTITUTION:When a linear light beams 4 projected on an object 1 to be measured from a slit projector 2 is observed form the right, a shift mechanism 9 of an optical path selector 10 is actuated for insertion of a movable reflector 8 into an optical path. The reflected light 13 made incident on a fixed reflector 7 is partly cut by the object 1 and therefore a light cutting image is not appropriate. Thus the light 13 is cut by the reflector 8 put into the optical path and never led to an image detector 3. In such a way, only the light received from the reflector 6 set in the direction having no dead angle is reflected and led to the detector 3. Thus it is possible to detect a form including no dead angle via a single image detector.

Abstract: PURPOSE:To prevent detection oversight from occurring by detecting a paragraph mark from a character string storage part, detecting a correspondent mark when a pair mark exists just before, and extracting a detected paragraph mark and a character string adjacent to the pair mark as partial character strings including type expression. CONSTITUTION:The paragraph mark such as a punctuation, a comma, and a period is retrieved sequentially starting from the forefront in the character string storage part 101. When an element just before the detected paragraph mark shows a closed parenthesis, retrieval is performed in a reverse direction from that position, and a correspondent open parenthesis is detected. A HIRAGANA(cursive form of Japanese syllabary) string adjacent to a detected open parenthesis and a non-HIRAGANA string just before or immediately after the parenthesis are extracted. The oversight of the detection of type expression can be further reduced by expanding the paragraph mark up to the comma and the period other than the punctuation.
