Title: Controller for rolling mill
Inventor: KOUNO YUKIHIRO
IPC: B21B39/08
Filed: 1979-04-13
Abstract: PURPOSE:To prevent the fluctuation of thickness of the steel strip, by utilizing the pinch roll for lessening the fluctuation of tension at cutting the steel strip, in the rolling mill provided with the cutter and the pinch roll between the final rolling stand and the coiling reel. CONSTITUTION:The steel strip 7 delivered from the final rolling stand 1 is coiled by the coiling reel 5 through the pinch roll 3 and the cutter 4. In prior to curring the steel strip 7, the motors 12, 11, are controlled by the coiling reel controller 17 and the pinch roll controller 15 in order to gradually reduce the tension of the coiling reel, and also, the tension given to the steel strip by the pinch roll 3 is gradually increased. The sum of these tensions is controlled so as to be equal to the former unfluctuated value of two tensions; only the tension required to coil the steel strip 7 is left behind in the tension of the coiling reel, and the tension required in drawing the steel strip 7 from the rolling stand 1 is transferred to the pinch roll 3; at this point, the command distributer 18 produces the cutting signal 23, and the cutter 4 cuts the steel strip 7. After this cutting work, the steel strip 7 is drawn from the rolling stand 1 by the tension of the pinch roll 3, so that the thickness of the steel strip 7 does not fluctuate.

Abstract: PURPOSE:To deal with multichannels by providing at least two resonators in which voice carrier frequency is set to resonance frequency and which correspond to different voice carrier frequency in first and second transmission lines. CONSTITUTION:3dB directional couplers 1 and 2 are provided, and the outputs of video transmitters and the outputs of voice transmitters are supplied to the input ports 3 and 4. Ports 5 and 6 are connected by a transmission line 7 and ports 8 and 9 which are in a conjugate relation with the ports 5 and 6 are connected by a transmission line 10. Resonators 11a and 11b, and 12a and 12b respectively set the voice carrier frequency of channels #1 and #2 to resonance frequency. Input voice signals to the coupler 2 are equally divided, approach the coupler 1 and reach a couples fo both couplers. The voice signals are reflected by either of the channels $# or #2 in a couple of couplers, return to the coupler 2, then are synthesized and are outputted to a port 13. Thus, the mixed output of a video and voice for the channels #1 and #2 can be obtained from the port 13. Consequently, the number of switches can be reduced in switching between broadcasting equipments of two channels and a common stand-by equipment.

Abstract: PURPOSE:To reduce the inductance of a feed path, and to expedite the risen of a discharge current so as to improve laser efficiency by constituting first and second feed paths for a laser discharge tube of flat plates parallel with each other. CONSTITUTION:The inductance formed by first and second feed paths 13A, 14A is in proportion to the length and the opposing gap distance (x) of each feed path, and is in reverse proportion to the width of it. Accordingly, provided that the length of each feed paths 13a, 14A is determined on the basis of the arranging condition of the laser discharge tube 7, the inductance can be reduced by reducing the opposing gap distance (x) of each feed paths 13A, 14A or enlarging the width. By reducing the inductance in this way, the rise of the feed current to the laser discharge tube 7 at the time of the discharge of a capacitor 4 is expedited, and the laser efficiency is improved.

Abstract: PURPOSE:To suppress the variation of signals on a signal line and facilitate accurate signal processing by a method wherein control electrode means are provided above and/or below the signal line provided on a substrate and the potential of the means is set at a certain potential. CONSTITUTION:The cathode 2 and anode 3 of a photodiode 1 are connected to the non-inversion terminal and inversion terminal of an operational amplifier 4 respectively. A reference voltage Vc is applied to the former and a signal line 5 is connected to the latter. Control electrode means 6 and/or 7 are provided above and/or below the signal line 5 and a voltage Vc' is applied to the means. The signal line 5 is connected to the output terminal of the operational amplifier 4 through a logarithmic diode 8.

By adjusting distances between the signal line 5 and the control electrode means 6 and 7, a leakage current and the like can be avoided so that the output voltage which corresponds to the incident luminous power accurately can be obtained. Moreover, for instance by providing a control electrode diffused layer 11 and a control electrode metal layer 14 above and below the signal line and by applying a voltage Vc' to both of the layers 11 and 14, the leakage current and invading current can be securely districted and the reliability of the control in the region where the output voltage signal is very small can be improved.

Filed: 1985-03-07
Abstract: PURPOSE:To attain D/A conversion even when a supplied digital signal exceeds the number of digits of input to a D/A converter by shifting the digital signal in response to the exceeded number of digits. CONSTITUTION:A control circuit 11 generates a signal E representing the exceeded number of digits when the number of digits of an input code data is larger than the reference number of digits by the prescribed number of digits. A shift circuit receiving the said signal E shifts the position of a decimal point of the input code data by the number of exceeded digits toward high-order in response to the signal E. After the output of the shift circuit is converted by a D/A converter 1, the result is fed to an LPF 12 via a switching circuit 2 controlled by the signal E. Even when the supplied digital signal exceeds the input number of digits of the D/A converter, D/A conversion is attained.

Abstract: PURPOSE: To attain a bumpless changing-over operation from a manual setting to a computer setting in a process control by constituting a changing-over method such that a set signal during a manual setting is applied to a computer and then a process is performed to bring a computer set value into coincidence with a manually set value whereafter the computer set value is output.

A changing-over operation from the manual setting to the computer setting is effected by changing-over of a gate 11 in response to a gate changing-over signal 12, but ordinarily, a bump occurs then since there is a difference between the two set signals. According to the invention, in order to prevent a bump, a process is performed to bring the computer set signal 13 into coincidence with the manually set signal 7 before a changing-over signal 12 is output from the computer 1.

Abstract: PURPOSE: To improve efficiency of luminescence by preventing O 2  in a p-type layer from lowering.  
     CONSTITUTION: Solution container 16 is sealed hermetically by lid 18 and Ga solution 22 containing the fixed quantities of zn and GaO is contained. To perform epitaxial growth of p-type GaP by using this device, an Ar gas atmosphere containing O 2  should be formed inside of substrate container 10 as well. The density of O 2   is set to 1 to 20%. Without this range, luminescence efficience never improves and with the density more than 20%, a substrate deteriorates. Then, containers 10 and 16, lid 18, substrate support desk 12, and sliding board 20 are made of a material inactive against O 2 . Otherwise, deterioration by O 2  is caused to lower the airtightness of the device and O 2  in Ar and dopants in the solution volatilize from a gap to make the acceptor density in the p-type layer uneven, so that characteristics and reproduciblity of an obtained element will deteriorate. Then, those are constituted by using independently or combinationally quartz, sapphire and other metal oxide.
