Abstract: PROBLEM TO BE SOLVED: To prevent soot lumps formed by being piled from being exhausted, together with an exhaust gas, when an engine is accelerated and in racing by preventing the soot in the exhaust gas from sticking to the wall faces of exhaust gas passages. SOLUTION: Heating bodies are arranged in wall faces, whose temperature is lower than the temperature of the exhaust gas passing through exhaust passages 10, 15, 20, 22, 25 and 26 from among the wall faces of these passages, and the wall faces of the exhaust passages 10, 15, 20, 22, 25 and 26 are heated, so that the temperature of these faces becomes higher than the temperature of the exhaust gas to give heat repulsive force to the soot in the exhaust gas from the wall faces of the exhaust passages 10, 15, 20, 22, 25 and 26.  In addition, the electric potential of soot in the exhaust gas is detected or soot in the exhaust gas is made to charge with electricity, and the exhaust gas passages are made to charge with electricity so as to have electric potential of the same polarity as that of the soot in the exhaust gas, and electrostatic repulsive force is given to the soot in the exhaust gas from the wall faces of the exhaust gas passages which was made to charge with electricity.

Title: Sizing agent for fiber
Inventor: KATAYAMA TETSUYA
IPC: C08F226/06
Filed: 1991-03-30
Abstract: PURPOSE:To provide the subject sizing agent containing a modified PVA having a specific functional group, imparting excellent adhesivity, cohesivity and abrasion resistance to a hydrophobic fiber and exhibiting excellent weaving efficiency. CONSTITUTION:A sizing agent containing a modified PVA having one or more kinds of functional groups selected from among primary amino group, primary ammonium base, secondary amino group and secondary ammonium base in the molecule is applied to a synthetic fiber or a natural fiber. The agent is effective for imparting excellent adhesivity, cohesivity and abrasion resistance to a hydrophobic synthetic fiber and improving the weaving efficiency of the fiber by preventing the end breakage in weaving. The weaving performance of a natural fiber such as cotton yarn can be improved by the use of the agent compared with the use of conventional sizing agent. The above PVA can be produced e.g. by copolymerizing a vinyl ester with an olefinically unsaturated monomer having a functional group such as primary amino group or with an olefinically unsaturated monomer having a substituent capable of forming the functional group by hydrolysis and subjecting the copolymer to saponification and hydrolysis.

Title: Industrial robot
Inventor: MURATA SATOSHI
IPC: B25J9/16
Filed: 1987-04-15
Abstract: PURPOSE:To easily change a connecting state without changing the contents of robot's operation by defining the connecting state of a peripheral device with the robot by a definition means, storing the defined contents in a storage means and referring the contents by a reference means to connect the peripheral device with the robot. CONSTITUTION:When data input from the n-th physical terminal is instructed by a robot operation part 2, a signal definition reference part 5 inputs data from the n-th physical terminal and refers a signal table stored in a signal definition storing part 4 to retrieve the n'-th logical terminal corresponding to the n-th physical terminal and to connect these terminals. Then, the reference part 5 judges whether the separation of the n-th physical terminal is instructed or not, and when the instruction exists, ends a program independently of data. When there is no instruction, the reference part 5 inputs data to the n'-th logical terminal and allows the operation part 2 to execute operation corresponding to the data. Thus, the connection of the physical terminal is not switched at the time of system change and the change of processed contents of the operation part can be also omitted.

Abstract: PURPOSE:To reduce the influence of ruggedness on the sample surface to perform accurate measurement, by detecting the height of the sample on a basis of the emission stereoscopic angle of fluorescent X-rays or continuous X-rays from the sample and by changing the position of the sample stand on a basis of this detection. CONSTITUTION:When slab sample 2 is carried in the direction of arrow 21, the height of the sample surface just under electron gun 4 is fluctuated as shown by virtual line 22 according to the flat degree of the upper face of sample 2. When irradiation point P of electron beam 5 will come off from optical axis 13 of spectroscope 12, shadow is generated by upper and lower edges of the lower end part of the first collimator 7, and therefore, the X-ray incident quantity becomes different between ionization chambers 14 and 15, and a current is supplied to servo motor 20 for the purpose of correcting this difference, and sample stand 3 is driven vertically in the direction of arrow 23, so that the element content of each part can be analyzed accurately independently of the flat degree of the sample surface.

Title: Abnormality detecting mechanism of metal detecting device
Inventor: TANAHASHI MASATAKA
IPC: G01V3/10
Filed: 1990-04-09
Abstract: PURPOSE:To find a decrease in metal detecting ability in its early stage and to improve the efficiency of the detecting operation by comparing the signal level from a metal detection part for a checking metallic body, which operates together with a conveying means, with a previously set level value. CONSTITUTION:The metal detection part 3 detects the checking metal tape 6 stuck on the outer peripheral surface of a belt 4 at the same time and its detection signal S1 is compared with a predetermined decision level. When the signal S1 is based upon only the tape 6, the level drops below a metal for eign matter decision level La, so a comparator 11 does not output a signal showing that metal foreign matter is found. Then when the detecting ability of the detection part 3 is normal, the level of the signal S1 becomes higher than a metal tape decision level Lb and an ability decrease finding lamp 9 does not illuminates, but when the detecting ability decreases, the signal S1 drops below the level Lb and a comprator 13 does not output a reset signal S3; and a timer circuit 15 outputs a time-up signal S4 a set time later, so a self-holding circuit 16 outputs the driving signal S5 for the lamp 9, which illuminates.
