Title: Electrostatic breakdown preventive element
Inventor: AKAMATSU YOSHINORI
IPC: H01L27/06
Filed: 1985-02-20
Abstract: PURPOSE:To operate the titled element positively at high speed with a comparatively small layout area while inhibiting the increase of input capacitance at a minimum by forming two bipolar-transistor sections sharing a collector region into the same semiconductor island. CONSTITUTION:When high-voltage pulses +Vp having plus polarity are applied to an external input terminal Pin, a thyristor by two bipolar-transistors Q1 and Q2 is shaped equivalently. When the high-voltage pulses +Vp exceeds a predetermined threshold (+ several hundred V), a potential difference is generated between a base and an emitter in Q2 because currents +Ic flow through base pinch resistors R1, R2, thus generating a positive feedback between Q1 and Q2, then triggering the thyristor. Accordingly, high-voltage pulses +Vp is clamped, thus protecting an internal circuit 10 from a breakdown.

Title: Controlling method for breadth of strip in hot strip mill
Inventor: HIROSE YUUJI
IPC: B21B37/00
Filed: 1980-03-11
Abstract: PURPOSE: To prevent a fluctuation of the height of looper and the thickness of the strip, by correcting the roll gap and the revolution number of the roll adjoining to the looper correspondingly to the quantity of computed correction value for the roll gap.  
     CONSTITUTION: The breadth deviation operator 22 operates the breadth deviation ΔW i  from the strip breadth W i  detected by breadth-meter 20 and the aimed breadth W 0  inputted from outside; the rate of breadth variation ΔW i /W i  is operated by the rate-of-breadth-variation operator 24. The function generator 26 produces a signal ΔU t  for the variation of the corresponding unit tension; depending on this signal ΔT t , the looper torque variation operator 28 operates the variation ΔT of the torque, which is then inputted to the controller 18; thereby, the controller 18 changes the torque of the looper 16. On the other hand, the revolution number correction operator 30 operates the revolution number correction operator 30 operates the revolution number correction value ΔN i-1  for the roll of the upstream side rolling stand  10 i-1 ; this correction value ΔN i-1  is inputted to the roll's revolution number controller 13 which thereby corrects the revolution number of said roll. Meanwhile, the roll gap correction operator 34 operates the roll gap correction value ΔS i  for the roll of  downstream side rolling stand 10 i , and inputs it to the roll gap controller 14 which  thereby corrects the roll gap of the downstream side rolling stand 10 i .

Title: Data transfer controlling system
Inventor: KIUCHI YUKIO
IPC: G06F11/00
Filed: 1981-03-04
Abstract: PURPOSE:To achieve a highly reliable data transfer control, by making parity check only at the transfer of effective data and transferring a fixed length data to other devices. CONSTITUTION:A data read-in operation from a memory 9 is performed by itself by a fixed data length only at a direct memory access DMA circuit 8. When a counter 5 overflows with the count of the effective data length only through the operation of the circuit 8, an FF2 is set and an AND gate 4 is inhibited. Thus, the result of parity check after the inhibition is not set to an  FF3. As a result, even if the data stored in the memory 9 is only the effective  data part and the remaining ineffective data is not a normal parity value, mis- detection as parity error can be avoided.
