Title: Controlling method for strip thickness in rolling mill
Inventor: KAMATA SHIYOUSEI
IPC: B21B37/72
Filed: 1980-03-31
Abstract: PURPOSE: To eliminate the off-gauges from the top and bottom ends of the strip, by simultaneously controlling the strip thickness and its tension to respective aimed values on the run-out side of each stand.  
     CONSTITUTION: The tracking device 9 receives the pulse count from the pulse generator 7 of each of stands No.1WNo.5 and the load variation signal from the load cell 8, detects the biting or the drop-out of the bottom end of the strip, and gives a timing command to the roll gap presetter 11 and the speed presetter 13. The presetters 11 and 13, when receiving this timing command, give the previously determined roll position command and speed command to the roll position controller 10 and the speed controller 12 of a necessary stand. The roll position controller 10 alters the roll gap of the necessary stand. The speed controller 12 alters the speed of motor 6 of the necessary stand. By these actions, the roll gap and the motor speed are placed under control, and the strip thickness is controlled while preventing the generation of off-gauges of the strip at biting the top end and at sending out the bottom end.

Title: Method and sensor for measuring l-tyrosine
Inventor: KARUBE MASAO
IPC: C12Q1/00
Filed: 1986-02-27
Abstract: PURPOSE:To decrease the influence of extraneous materials and to make measurement with high sensitivity by immobilizing an L-tyrosine decarboxylase onto a gas permeable membrane of a carbon dioxide electrode. CONSTITUTION:The L-tyrosine in, for example, a soln. such as bodily fluid is dispersed into tyramine and carbon dioxide by the effect of the L-tyrosine decarboxylase. The formed carbon dioxide is permeated through the gas permeable membrane immobilized with the L-tyrosine decarboxylase and the carbon dioxide permeated through said membrane is metabolized by selectively metabolizable microorganisms. The decrease of the oxygens concn. generated at this time is measured as a current value by an oxygen electrode and the change of the carbon dioxide is known from the change rate of the current value, by which the concn. of the L-tyrosine is measured. Since this L-tyrosine sensor uses the amperometic carbon dioxide electrode using the microorganisms as a transducer, the quick measurement of the L-tyrosine with high sensitivity is made possible and the measurement is less influenced by the extraneous materials.

Title: Over-voltage preventive device for vacuum opening/ closing device
Inventor: MATSUI YOSHIHIKO
IPC: H01H33/59
Filed: 1988-02-23
Abstract: PURPOSE:To prevent arcing surge over-voltage which is hazardous for a vacuum opening/closing device (VCB) and circuit component apparatus of the system by issuing a pole opening command while a shutoff command of the VCB delays the output in a specified timing to the load zero point. CONSTITUTION:An over-voltage preventive device is composed of a zero point sensor 41 for sensing of the zero point of a track current, a delay circuit 43 for delaying of sensed zero point detection signal, and a logic product circuit 44 to obtain the logic product of this delay signal and a pole opening command of a vacuum opening/closing device (VCB). Arcing time-max. generating voltage characteristic is determined in advance, and hazardous arcing time zone is obtained from this characteristic, and this time is assumed to be delay time td of the delay circuit 43. And now a pole opening command is emitted to the VCB after a delay of the specified time td to the load current zero point from emission of the pole opening command. Thereby pole opening is made for electrodes of the VCB at the target pole opening point while the hazardous arc time zone is avoided, that prevents generation of hazardous arcing surge over-voltage.
