Abstract: PURPOSE: To improve the thickness control accuracy and the yield, by arithmetically processing  a part of output of the precision thickness control system, and by installing the monitor means for  feedback to the rough thickness control system.  
     CONSTITUTION: The product thickness deviation ΔhN detected by the gaugemeter 26 is inputted to the precision thickness controller 30, and undergoes the gain correction with the rolling speed;  after that, the output is branched. One branch undergoes the PI control operation as well as the  conventional method, and adjusts the rotational speed of the work roll 18a of the final rolling  stand through the speed controller 28. Another branch is inputted to the monitor circuit 50, and  undergoes the PI control operation with the operational constant different from the precision  thickness controller 30, and is inputted to the rough thickness controller 36. The thickness deviation Δh2 on the exit side of the second rolling stand 16 is also inputted to this controller 36. When  the monitor circuit 50 produces no output, the zero control is carried out so as to make zero the  thickness deviation detected by the gaugemeter 32. When the monitor circuit 50 is producing the  output, an offset corresponding to this output causes in the thickness deviation on the exit side of  the second rolling stand, however, this offset is finally dissolved in the rough control system 24.

Title: Data ciphering system
Inventor: ISHII YASUHIRO
IPC: H04L9/12
Filed: 1990-05-30
Abstract: PURPOSE:To execute ciphering/decoding processings even if a data length is short by taking the exclusive OR of a result obtained by means of ciphering an initial chain value and plaintext data and setting plaintext data as cryptotext data. CONSTITUTION:The ciphering/decoding processings are executed with a data Encryption Standard (DES) arithmetic circuit 1 executing the operation of a DES system as a center. When the data length of plaintext data executing the ciphering processing is less than a block length, the initial chain value is ciphered and the exclusive OR between the ciphered initial chain value and inputted plaintext data is taken, whereby plaintext data is set to be ciphered data. Thus, even a short plaintext less than one block can be ciphered by taking the exclusive OR with data obtained by ciphering the initial chain value. Furthermore, a next ciphered block is read in advance and therefore the cryptotext block inputted from an opposite direction can successively be decoded.

Title: Electron beam sensor
Inventor: SHOJI TOSHIO
IPC: G01T1/20
Filed: 1989-06-06
Abstract: PURPOSE:To obtain an electron beam sensor having durability and high efficiency by providing a surface in a ground glass state and a mirror surface which is opposed to the ground glass surface to a plate of an oxide monocrystal and applying nonreflective coating with respect to fluorscent to the mirror surface. CONSTITUTION:Since the nonreflective coating of a dielectric 3 is applied to the surface of the electron beam sensor 10, almost all light 5a advancing in a vertical direction to the surface of the electron beam sensor among the fluorescent 5 generated by an electron beam 4 which is transmitted through the oxide monocrystal 1 is emitted. Since a material having a value approximate to the 1/2th power of refractive index of the material of the sensor is selected as the nonreflective coating of the dielectric 3, a critical angle (theta) generating total reflection becomes large and light which is reflected on the surface and scattered again on the surface in the ground glass state becomes small in comparison with the powder of a phosphor. Therefore, the life of the fluorscent becomes shorter when the powder of the phosphor is used. Besides, since the defect of a crystal is small in comparison with the powder in the case of the oxide monocrystal 1, energy is smoothly propagated and an element having the excellent efficiency of light emission is obtained.

Title: Radio commutation system
Inventor: SERIZAWA MUTSUMI
IPC: H04L12/28
Filed: 1988-06-09
Abstract: PURPOSE:To prevent collision in a transmission line by permitting respective base stations to calculate likelihood showing certainty in radio signals received from slave stations, to decide a time based on the likelihood and to transmit the signals to a master station through the transmission line after a prescribed time. CONSTITUTION:The signals from the slave stations 21, 23 and 25 are received in respective base stations 11, 13 and 15. The reception signals are demodulated in a demodulator 37 and are supplied to a likelihood calculation circuit 35. Likelihood showing the certainty of a demodulation signal is calculated, the time based on the likelihood is waited for, and transmission is executed only when the transmission line 17 is in an used state. Thus, transmission signals from the base stations 11 and 13 are prevented from colliding. A waiting time corresponding to likelihood calculated in the circuit is decided in a time decision means provided in a LAN node processor 33. When likelihood is large, the waiting time is set short, and it is set long when likelihood is small. Thus, the base station which has received the packet signal of largest likelihood transmits the signal to the transmission line 17 fastest and the master station 20 can receive it at the largest probability.
