Title: Tension controller for rolling mill
Inventor: KAWASE MASAHIRO
IPC: B21B37/52
Filed: 1988-06-07
Abstract: PURPOSE:To prevent calculation errors of tension from propagating to a downstream stand by calculating the relation between the tension of rolled stock on the inlet side of the rolling mills of the next stage and a width dimension of the outlet side thereof recurrently to obtain the coefficient of the recurrent formula and consequently, operating the tension of rolled stock on the inlet side of the rolling mills of the next stage to control the tension. CONSTITUTION:There are provided a coefficient operating part 20 in which a relation between a measured value of width dimension by a width meter 18 on the outlet side of a rolling mills i-std of the next stage and an operated value of tension in the rolling mills i-std of the succeeding stage is calculated recurrently as a linear equation (a divergent quantity bi, a preceding stage tension (i-1)) to output a coefficient of the recurrent equation and a width system tension arithmetic unit 6 which obtains coefficients of the recurrent equation outputted by the coefficient operating part 20, substitutes the measured value of the width dimension by the width meter for the recurrent equation and operates a tension on the inlet side of the rolling mills i-std of the next stage. Then, the output of a rolling mill driving electric motor 4 is changed by the operating value of the width system tension arithmetic unit 6 to fix the tension on the outlet side of rolled stock. In this way, errors in tension calculation can be cut off from propagation.

Title: Infrared reflection mirror and its production
Inventor: KASAMA ICHIRO
IPC: G01V8/14
Filed: 1994-06-21
Abstract: PURPOSE:To provide a reflection mirror having high durability and high infrared reflectivity. CONSTITUTION:The reflection mirror is constituted of a mirror body 2 obtained by sticking a reflection film 5 on the surface of a pedestal 4 and a mount for the mirror body 2. The mirror body 2 is obtained by vapor-depositing silver 7 functioning as a reflecting material on the surface of a resin film 6 and further forming a coating layer 8 functioning as a protective film on the surface. The mirror body 2 is fixed on the mount by a fixing tool in a state where a liner is interposed. Thus, the mirror body 2 is curved with specified curvature. By arranging such a reflection mirror and reflecting an image on an infrared camera at the high reflectivity, the infrared camera picks up and processes the image at a spot where it is not directly taken without correcting temperature. Then, the high durability is obtained by the coating material.

Abstract: PURPOSE:To conduct a highly precise analysis quickly and to improve the efficiency of crystal growth by using a substrate not containing an element to be analyzed at least in the surface whereon a crystal is made to grow and by conducting an X-ray photoelectron analysis in a crystal growth chamber or in a vacuum chamber connected thereto. CONSTITUTION:A substrate 1 not containing an element of an object of analysis at least in the surface whereon a crystal is made to grow is put in a substrate sending-in chamber 7. A pressure inside the sending-in chamber 7 is reduced to a vacuum being equal to the one inside a conveying chamber 61 and the substrate 1 is conveyed into the conveying chamber 61. After a pressure inside the conveying chamber 61 is reduced to a vacuum being equal to the one inside a GSMBE growth chamber 4, the substrate 1 is conveyed into the GSMBE growth chamber 4. One atomic layer of a compound semiconductor constituting atom A is made adsorbed on the substrate 1 in the GSMBE grown chamber 4 and an XPS intensity in this state is measured in an XPS analysis chamber 5. In the GSMBE growth chamber 4, subsequently, an organic metal gas AR3 is applied onto the substrate 1 for the same time as for the above adsorption and the substrate 1 is transferred to the XPS analysis chamber 5 to be analyzed. The XPS intensity of the compound semiconductor constituting atom A thus obtained is compared with the XPS intensity of one atom layer obtained previously, and thereby the speed of growth is determined.

Abstract: PURPOSE:To attain surely excellent communication quality, by converting an input binary digital signal into separate blocks and transmitting them, and reproducing them into the original signal at the receiving side so that noise on a transmission line is spread in time and concentrated noise is brought into random noise. CONSTITUTION:A binary digiral series having a clock period T applied to a signal input terminal 8 is converted into a parallel digital series at the period NT at each block by using N-digit as one block at a series-parallel converting circuit 9 and applied to an input terminal group of a transmission signal converting circuit 11. A signal value of the input terminal group of an optional block is imaged linearly at the circuit 11. Each block of N-digit of the binary digital input series is converted into a transmission signal block of PAM pulse train in M-digit and transmitted to a transmission line 16. The receiving signal of the transmission line 16 is demodulated at a receiver 17 and the original transmission signal is reproduced. A receiving synchronizing device 18 detects a block synchronizing signal and generates various clocks required to operate a series- parallel converting circuit 19 and a parallel-series converting circuit 24. The parallel binary digital series is converted into the N-digit series having the clock period T at the circuit 24, and outputted to a signal output terminal 25.

Filed: 1993-05-19
Abstract: PURPOSE:To make registered target information match with registered information even when it takes a long period of time to perform title input operation by transferring an automatic repeat mode wherein information being played is repeatedly reproduced when a title input mode is set during the musical performance. CONSTITUTION:With a key for title input pressed, the setting state of a current operation mode is saved in a RAM 8 and the repeat state wherein music on a disk which is being played is repeatedly reproduced is set. An inputted title is registered with a memory key pressed. When the input of the title ends, a title input mode is reset. With the memory key pressed, the state of the automatic repeat is reset and the setting state of the original operation mode saved in the RAM 8 is restored. Therefore, when the title input mode is set, the music which is currently reproduced, i.e., music as the target of the title input is repeatedly reproduced, so a sufficient title input time can be secured.
