Title: Controller for rolling mill
Inventor: MIYASAKA NAOTAKE
IPC: B21B37/00
Filed: 1994-03-08
Abstract: PURPOSE:To execute stable tension control even when rapid and excessive tension variation is generated by disturbance or the like. CONSTITUTION:When disturbance due to the manual intervention by an operator or the like is generated, the rapid tension variation is absorbed by freely changing the height of a looper arm 2. On the other hand, tension T is determined based on each detected signal from a load detecting means 14, torque detecting means 15 and acceleration detecting means 16 by a tension detecting means 11A. A tension control signal is outputted based on deviation between a detected value T and a command value T* with a tension control amplifier 12. Since a loop height theta is greatly changed, the deviation theta between theta and theta* is increased and large output is added to a speed controller 9 with a loop height control amplifier 7. But, the responsiveness of this control amplifier 7 is slower than that of the control amplifier 12. That is, rapid tension variation is first absorbed by freely changing the loop height and this loop height is controlled so as to return to the original height taking a neccessary time.

Filed: 1981-03-16
Abstract: PURPOSE: To obtain the titled filter with good filterability and high reliability by forming a filter member in such a manner that a continuous recessed and protruded shape is provided in the flowing direction of a fluid and pleats are formed on the filter surface thereof concentrically.  
     CONSTITUTION: A filter member 1 has a continuous recessed and protruded shape toward the flowing direction of a fluid and said shape is integrally molded in an almost concentrical circle form to the right angle direction against the flowing direction of the fluid. At the same time, pleats 11 are formed over the entire surface of a filter surface and, as the whole, molded in a concentrical pleat form. In this filter member, the fluid containing fine particles is flowed into the filter member 1 through a punching metal 3b and, after fine particles are removed, the purified fluid is flowed out through a punching metal 3a. As the result, the filter has a wide filter surface and the fluid is uniformly passed through the filter surface as well as pressure loss due to passing resistance is reduced and said filter has good collecting efficiency, excellent durability and high reliability.

Title: Error correction device
Inventor: KOYAMA MASAYUKI
IPC: H03M13/15
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of a reed Solomon error correction device by using a 2-way first-in last-out FILO that applies a consecutive FIFO function to a different group of codes. SOLUTION: Coefficients of an error location polynomial σ(x) and an error evaluation polynomial ω(x) obtained by using the Euclid method are obtained in the order from a final digit to a head digit of a code. A correction device 3 starts chain search from an end byte to a head byte of the code accordingly. Each group of data RSIN is inverted for the digit order at a 2-way FILO 6 and the result is given to the correction device 3 in order to cope with the search sequence. Since the digit sequence is inverted in the code corrected by the correction device 3, the digit sequence is restored at a 2-way FILO 4 to restore the inverted sequence and a resulting code SOUT is outputted. The 2-way FILOs 4, 6 are realized by, e.g. shift registers.

Title: Corrosion preventive method for underground buried metallic pipe
Inventor: KINOSHITA AKIRA
IPC: C23F13/00
Filed: 1992-02-25
Abstract: PURPOSE:To efficiently execute drainage when the stray current from electric train rails runs in an underground buried metallic pipe. CONSTITUTION:The stray current 111 from an electric train 14 flows into a pipe 12 which is the metallic pipe buried in soil 11. An inflow current 120 flows to a potential control type force drainer 20 from a drainage point 19. The amplifier AMP 2 of the potential control type force drainer 20 increases the internal resistance of a second transistor(TR) 22 to decrease a drainage current 122 and to prevent overprotection when the potential of the drainage point 19 changes to a base side with the potential of a reference electrode 18 as a reference. The internal resistance of the second TR 22 decreases to increase the drainage current 122 and the potential of the drainage point 19 is maintained at the base by utilizing the drainage current when the potential at the drainage point 19 changes to the noble side. A protective current 121 is supplied from a current rectifier 23 via a first transistor 21 to protect the pipe 12 when the drainage current does not flow and when the protective current cannot be maintained by the drainage current alone.

Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To judge a dispensing action for detecting a liquid level, choking, short sample and bubble suction with a simple accurate method. SOLUTION: A syringe 4 is used to suck and discharge a liquid sample 2. A gas flow meter 7 flowing in a tube 6 and nozzle 3 connected to the syringe 4 is provided in an automatic dispenser. While the syringe 4 is put into the discharging action with fixed speed, the nozzle 3 is lowered to the sucked specimen.

Choking in the nozzle 3, amount shortage of detected specimen, completion of sucking bubbles or the like are detected in response to the varied amount of the gas flow rate in the sucking action to control the vertical operation of the syringe 4 as nozzle 3 correspondingly.

Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To appropriately detect the release of droplet, to reduce spatters at the time of releasing droplet and causing short circuit and to stabilize welding by eliminat ing influence of short circuit and disturbance. SOLUTION: A droplet-release detecting means 50 detects the release of droplets from a welding voltage, and a short-circuit detecting means 51 detects the short circuit. An output compensating means 52 removes the influence of the short circuit in the signal for detecting the release of the droplet, then outputs the signal to a pulse waveform generating means 53 as an output compensating signal.  When either of the output compensating signal or the short circuit detecting signal is inputted, a pulse period tp, the means 53 outputs a stationary pulse waveform set by a base period tb, a pulse current Ip and a base current Ib; besides when the output compensating signal is inputted, the means 53 outputs the stationary pulse waveform from the point of time passing tr while being reduced to a compensating current Ir with that inputted point of time as a starting point during the prescribed compensating period tr, thereby reducing spatters through the current reduction at the time of the droplet release, accelerating droplet formation, and stabilizing welding by uniformizing a droplet detaching period.
