Abstract: PURPOSE: To provide a standard solution of cyanide, which is stable at the time of reservation for long time and has a feature for containing complicated cyanide.  
     CONSTITUTION: 1.25 g (19.2 millimol) of potassium cyanide is dissolved in about 500 ml of distilled water in the messflask of one litter, for example. Then, 1.127 g (9.6 millimol) of zinc cyanide is added, distilled water is added to the position of a mark and solution is diluted. Zinc cyanide is dissolved by stirring. An insoluble part is filtered by using a ribbed filter. The content of cyanide in the solution is obtained by silver titration by using a potential difference indicator in an alkali medium. A electrode:silver connection battery and 1 ml of solution of 0.1 mol./l of silver nitrate correspond to CN-5.2036 mg. The solution of prescribed content is prepared by diluting a part from preserved solution.

IPC: F01N3/28
Filed: 1977-10-28
Abstract: PURPOSE: To reduce NOx in exhaust gas to harmless N 2  with a cheap carbon source in the absence of catalyst by placing the source in an exhaust system and reducing the NOx with the carbon of the source.  
     CONSTITUTION: An internal combustion engine sucks a mixed gas of fuel and air into combustion chamber 5 demarcated by engine casing 3 and piston 4 from suction boat 2 which is opened or closed by suction valve 1, and it exhasuts exhaust gas toward exhaust duct 8 from exhaust boat 7 which is opened or closed by exhaust valve 6. Vessel 10 housing a great deal of granular solid carbon 9 is set to duct 8 so that it crosses the exhaust gas current flowing through duct 8. When the exhaust gas exhausted from boat 7 into duct 8 is passed through vessel 10, carbon 9 is heated to heat NOx in the gas, whereby the NOx are reduced to harmless N 2  by the reducing action of a reaction product of carbon 9 and O 2 , i.e. CO. Unburned CO, hydrocarbon, etc. in the gas passed through vessel 10 are then oxidized in reactor 11 provided to the downstream side of vessel 10 to purify the gas.

Title: Motor-driven cylinder device with expansion rod positioning mechanism
Inventor: KIMURA KUNIMASA
IPC: H02K7/06
Filed: 1995-04-28
Abstract: PURPOSE: To make the speed pattern related to an expansion rod and stopping position of the rod when the rod is expanded or contracted actually feelable by providing a controller which controls an induction motor based on signals from a sensor and rotational position detecting means. CONSTITUTION: The position at which the deceleration of the expansion rod 11 of the main body 1 of an expanding or contracting motor-driven cylinder is started is selected in advance by adjusting the positions of proximate switches. When a motor-driven cylinder device is started, the threaded shaft of a screw mechanism is rotated by the induction motor 14 of the main body 1. As the threaded shaft rotates, an indicating member moves through a nut and the proximate switches detect the presence of the indicating member. Thereafter, the rotating speed of the motor 14 is gradually decreased in accordance with a command from a controller 28 while the rotational amount of the threaded shaft is continuously detected by means of an rotary encoder and, when the rod 11 is expanded to a required length, the rotation of the motor 14 is stopped.

Abstract: PURPOSE:To accurately fill a specified amount of liquid by a method wherein a measuring rod which ascends with rising of a plunger and a sensor which detects the location of the measuring rod is provided, and a weight having a specified weight is put on the plunger. CONSTITUTION:A barrel 12 is installed on a cylinder 2, and a weight 16 is mounted on an upper rod of a plunger 14. When pressurized liquid is supplied to the barrel 12, the plunger 14 is moved up by the pressure of liquid, causing a measuring rod 20 connected to the plunger 14 to be pushed up and a measuring dog 18 attached to the plunger 14 to begin to rise. When the measuring dog 18 arrives at a measuring point sensor 26 and an ON signal of the measuring point sensor is output to a sequencer 30, a solenoid valve 32 is closed and pressure air supply to the cylinder 2 is stopped so that liquid supply to the barrel 12 is stopped. At this time, when the weight of the weight 16 is set at adequate value according to the viscosity of the liquid, the liquid can be stably filled without a leakage of liquid from the clearance of the plunger and mixing of air into the liquid.

Abstract: PURPOSE:To prevent any winding quality defect such as flaws on a roll material, winding looseness, overtightness or the like from occurring as well as to reduce the extent of equipment failure by providing plural pieces of nozzles for air suction in the inner direction of a mandrel. CONSTITUTION:In a mandrel 5 wound with a strip body, plural pieces of nozzles 4 for air suction are provided in the inner direction of this mandrel 5.

Subsequently, the winding operation on and after the second wind is carried out without the vacuum suction, and when a coil of the strip body 1 is pulled out, a pressure fluid is made so as to be blown out of the peripheral surface of the mandrel 5. With this constitution, integral winding quality is thus improvable.

Filed: 1989-05-25
Abstract: PURPOSE:To realize a matrix array which can surely and easily redress even a faulty line which occurs after completing the matrix array by providing an auxiliary electrode pattern which intersects with an electrode pattern on one substrate on the other opposed substrate. CONSTITUTION:The electrode patterns 3a and 3b which are row and a column are formed on one substrate 1 of two opposed substrates of the LCD matrix array and the auxiliary electrode pattern 4 which intersects with either electrode pattern 3b is provided on the other substrate 2. For example, in the case that the line of the electrode pattern 3 on the substrate 1 is disconnected at a point P1 in the matrix array thus constituted, a signal inputted from the A side of the electrode pattern 3 is transmitted only to the point P1 and is not transmitted to a B side. Then, the intersection parts A and B of the electrode pattern 3 with the auxiliary electrode pattern 4 on the substrate 2 are made to be con nected by laser processing. Thus, the signal inputted from the A side passes the auxiliary electrode pattern 4 on the substrate 2 and is transmitted to the point P1 through the intersection part B, thereby recording the fault of the line.

Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To improve usability and work quality. SOLUTION: In a fastening machine 1, a working set source voltage is set by a source voltage setting part 10, and a source voltage applied on a motor 27 of the fastening machine 1 is compared with the set source voltage by a voltage detecting circuit 6 to decide whether a voltage is uneven. When it is decided by the voltage detecting circuit 6 that an applying source voltage and a set source voltage are uneven, based on the decision, motor drive operation of a drive control circuit 9 is stopped by the voltage detecting circuit 6. Thus, even when a different source voltage is erroneously connected to the fastening machine 1 having given source voltage specifications, the motor 27 is brought into a stop, whereby a situation where the fastening machine 1 is erroneously used at a source voltage difference from a proper source voltage is prevented from occurring.

Abstract: PURPOSE:To attach sufficient quantity of toner which has stable electrostatically charged amount to a developing roller and to form a high-quality visible image by providing an electrostatic charging means for forming a fine closed electric field near the electrostatically charged surface of the photosensitive layer of the developing roller. CONSTITUTION:The developing roller 5 in a developing device 2 is constituted of a conductive substrate 52 and the photosensitive layer 53 on the substrate 52, and an electrostatic charging member 60 for electrostatically charging the layer 53 is arranged. When the layer 53 is electrostatically charged by impressing voltage from a power source 55, the innumerable fine closed electric fields are generated on the surface of the layer 53 because the layer 53 has the particles of non-conductive semiconductor which are dispersed in binding resin whose resistance is high, and the intensity of the electric field gets very high by what is called an edge effect. Therefore, the sufficient quantity of toner which has the stable electrostatically charged amount is attached to the surface of the developing roller by a toner supply roller 6 and the high-quality visible image is formed on a photosensitive drum 1.
