Title: Shape control method for continuous rolling mill
Inventor: OKUDA TAKAYASU
IPC: B21B37/44
Filed: 1990-04-25
Abstract: PURPOSE:To efficiently eliminate planar strain due to the difference of rolling condition in the width direction by controlling the shape by correcting the temp. distribution in the width direction according to the distribution of the correction quantity of temp. in the width direction of a material to be rolled. CONSTITUTION:The distribution of the correction quantity of thickness in the width direction of a material 1 to be rolled on the outlet side of a rolling roll 8 is determined with a shape sensor 12, 12a and converter 14a for correction quantity of shape-correction quantity of thickness on outlet side. From this distribution, the distribution of correction quantity of deformation resistance in the width direction of the material 1 to be rolled is determined with a converter 14b for correction quantity of thickness on outlet side-correction quantity of deformation resistance. From that distribution, the distribution of correction quantity of temp. In the width direction of the material 1 to be rolled is determined with a converter 14c for correction quantity of deformation resistance- correction quantity of temp. According to that distribution, the temp. distribution in the width direction of the material 1 to be rolled is corrected with a temp. controller which is arranged in front of the rolling roll 8. In this way, control can be done with good responsiveness.

Title: Production of polymer terminated with fluorine- containing group
Inventor: SATOU TOSHIAKI
IPC: C08F20/00
Filed: 1983-06-17
Abstract: PURPOSE:To produce the titled polymer having excellent properties of a fluorocarbon surface, by radical-polymerizing a radical-polymerizable monomer in the presence of a fluorine-containing thiol. CONSTITUTION:A radical-polymerizable monomer (e.g., styrene, acrylonitrile, vinyl chloride or ethylene) is radical-polymerized in the presence of a fluorine- containing thiol (e.g., a compound of formulas I or II). A polymer terminated with a fluorine-containing group can be obtained. Although this polymer does not differ at all in bulk properties from usual polymers, the water and oil repellency of, for example, a film cast from a solution of this polymer are extremely greater than those of films of usual polymers. Therefore, it is possible to obtain a molding which is easily subjected to a bonding work and excellent in surface water and oil repellency. By the introduction of fluoroalkyl chains to the terminals of a water-soluble polymer such as a (meth)acrylic acid polymer, the resulting polymer can exhibit surface activity so that it can be used also as a new fluorine-containing surfactant.

Title: Hall element circuit
Inventor: NAITO HAYATO
IPC: G01R33/07
Filed: 1993-04-13
Abstract: PURPOSE:To obtain two kinds of signals and then to expand the use by connecting a voltage-dividing resistor between a power inputting terminal of a Hall element and a power supply and by taking out signals which are generated according to a change in input resistance of the Hall element due to a change in a magnetic field from a connection between the voltage-dividing resistor and the power inputting terminal of the Hall element. CONSTITUTION:A Hall element H is located near a magnetic field. A voltage- dividing resistor R is connected between a power inputting terminal of the Hall element and a power supply Vcc (GND). Then, signals (c) which are generated according to a change in input resistance of the Hall element H due to a change in the magnetic field are taken out from a connection between the voltage-dividing resistor R and the power inputting terminal of the Hall element H. When the Hall element H is influenced by the change in the magnetic field, the input resistance of the Hall element H changes. Therefore, signals taken out from the connection between the resistor R and the power inputting terminal of the Hall element H is a voltage signal (c). The voltage signal (c) has a frequency double the cycle of output signals (a) and (b) of the Hall element H.

Title: Automatic shutoff valve
Inventor: KITA KAORU
IPC: F16K31/40
Filed: 1989-04-28
Abstract: PURPOSE:To supply a constant flow rate of fluid by controlling the opening area of a secondary pressure control valve of a pilot outflow passage with a bourdon tube which displaces according to the pressure in the outflow passage, opening the secondary pressure control valve with a constant amount at the time of solenoid opening of the outflow passage, and controlling a main valve opening. CONSTITUTION:When a solenoid valve S is closed under the condition of an inflow passage 3 supplied with water, a pilot outflow passage 11 is closed, water in the inflow passage 3 raises the pressure from a pilot inflow passage 10 to a pressure control chamber 8, and together with a spring 9 closes a main valve 5. When the solenoid valve S is opened, water in the control chamber 8 is drained to an outflow passage 4, the pressure in the control chamber 8 is lowered, the main valve 5 is raised, and water is sprayed out for example with five sprinklers. When ten sprinklers are opened, the water pressure in the outflow passage 4 decreases, a secondary pressure control valve 13 is opened with the pressure decrease in a bourdon tube 16, the pressure in the control chamber 8 further lowers, and the opening area of the main valve 5 increases. As a result, the water flow rate can be prevented from decreasing.
