Title: Method for setting sheet crown
Inventor: KAWASE HIROSHI
IPC: B21B37/00
Filed: 1989-07-20
Abstract: PURPOSE:To shorten a correcting term of a mill and to improve the precision for calculating sheet crown and the yield of a product by calculating a deviation between the sheet crown calculated from a rolling condition and a measured value and modifying a reference correction value successively. CONSTITUTION:The sheet crown on the outlet side of the mill where a work roll shift is performed differs in size according to the work roll shift position even under the same rolling condition. The deviation between the sheet crown measured on the outlet side of the mill and the sheet crown calculated based on the rolling condition is converted by a function having the work roll shift position as the variable for one side into a reference correction value and is used for correction of the calculated value of the sheet crown calculated based on the rolling condition. The reference correction value is used in setting and calculating the sheet crown in the next time by storing measured data and classifying them under each condition.

Title: Actuation detecting circuit for latching solenoid
Inventor: KANEKO YOSHIYUKI
IPC: F16K31/06
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To enable an actuation detecting circuit to surely make bottom detection with a simple circuit configuration composed of general purpose parts by providing a charging means which charges a capacitor until a second signal becomes a prescribed value in the circuit. SOLUTION: Immediately after a solenoid 3 is energized, the capacitor 703 of a CR delaying circuit is charged to the output voltage of a diode 705. When the current of the solenoid 3 increases and an original signal exceeds the output voltage of the diode 705 thereafter, the delaying circuit starts to follow the original signal. When the current of the solenoid further increases and the magnetic field generated by the solenoid 3 reaches the value required for moving a plunger, the delaying circuit starts the plunger and generates a bottom signal. Therefore, the delaying circuit can flexibly and inexpensively cope with various operating conditions without using the port of a microcomputer, etc., and, in addition, can prevent the occurrence of erroneous detection when the current value of the solenoid 3 is small.

Title: Production of non-slip tile and production unit therefor
Inventor: SUGIURA TAKAO
IPC: C04B41/89
Filed: 1995-06-29
Abstract: PURPOSE: To obtain a tile having high non-slip performance and stable in quality. CONSTITUTION: This non-slip tile is obtained through the following processes: the respective surfaces of tile bodies 2 laid nearly horizontally are dispersedly sprinkled with an appropriate amount of refractory fine granules 4 with a melting point higher than the welding temperature of a glaze 3; the respective surfaces of the tile bodies 2 bearing the refractory fine granules 4 are coated with the glaze 3; and the tile bodies 2 after glazed are baked at a temperature higher than the welding temperature of the glaze 3 but lower than the melting point of the refractory fine granules 4. According to the above production method, as the refractory fine granules 4 are scattered on the tile bodies 2 in advance without their mixing with the glaze 3 followed by conducting a glazing operation, the refractory fine granules 4 can be easily dispersed uniformly; besides, because the refractory fine granules 4 do not get in the pump for feeding the glaze, the maintenance of the pump can be conducted easily and the pump is hard to be damaged.

IPC: G11B20/10
Filed: 1981-11-24
Abstract: PURPOSE:To realize the stable demodulation regardless of a change of the tape speed, by always comparing the interval of the preceding arrived pulse with the interval of the next input pulse. CONSTITUTION:The PE modulating signal is reproduced and then converted into the rectangular wave to obtain the signal A. This signal A is applied a terminal 1. Thus the pulse B synchronous with the edge of the detector 2 is delivered from the detector 2 to obtain the pulses C and D through the delaying units 3 and 4 respectively. The pulse D is applied to the base of a switch transistor 5 and discharges the electric charge which is charged to a capacitor 6. In this case, the both-terminal voltage of a capacity 6 that is obtained immediately before the electric charge of the capacity 6 is discharged by the pulse D is stored in a sample holding circuit 8 by means of the pulse C. The both-terminal voltage of the capacity 6 is compared 10 and 12 with the voltage of the circuit 8. Then a change is detected between the time during which the next pulse D arrives and the time of the preceding pulse D.

Title: Method and apparatus for reutilizing waste solution in sampled liquid chromatography
Inventor: ONODA TOMOKICHI
IPC: G01N30/26
Filed: 1989-07-21
Abstract: PURPOSE:To obtain a method for reducing the necessity for the treatment of a waste solution and the fear of environmental pollution by converting the whole flow passage of sampled liquid chromatography to a closed loop system by combining a system and a waste solution regenerating system. CONSTITUTION:After a specimen is injected in the liquid 14 from an eluate storage tank 13 through a specimen injection means 17, the specimen-containing liquid is allowed to flow down to a flow passage change-over means 25 through a sampling column 18. A detection means 19 detects the specimen component in an eluated solution and said liquid is taken in a sampling passage 21 through the change-over means 25 when the specimen is contained sufficiently to be recovered in a sampled solution storage tank 22 and sent to a waste solution recovery passage 32 when the specimen is not contained sufficiently to be once stored in a waste solution storage tank 34. A waste solution 33 is allowed to forcibly flow down through a removing column 38 and compared with the first eluate component by a detection means 39 and recycled to the eluate storage tank 13 only when said solution can be reutilized. By this treatment cycle, a solution containing a large amount of the specimen component is recovered as a sampled solution 23 and a solution not containing the specimen component sufficiently can be also reutilized and therefore, the necessity for the treatment of the waste solution is reduced to contribute to the prevention of environmental pollution.
