Patent GB-352909-A (GB)
Title: Improved manufacture of artificial threads or films
IPC: D01F2/28
Filed: 1930-01-09
Abstract: All kinds of artificial threads and films whether they be made from solutions of cellulose, cellulose esters or ethers, glue, or albuminous substances, are improved in strength by subjecting the threads and films during the process of spinning after being brought to a suitably swollen state, to an extensive stretching or drawing. The spinning may be carried out by the single bath method or by multiple bath processes.  In the case of cellulose esters and ethers, the baths used may be chemically inert, for example, organic solvents; but it is possible with these and with other spinning solutions to use baths in which regeneration is at the same effected. Threads &c. of regenerated cellulose such as are obtained from viscose and from cuprammonia cellulose solutions may be swollen in strongly alkaline baths.  Stretching may be carried out in the swelling bath, or after the threads &c. leave the bath; and the swelling agent may be applied as a vapour.  By a suitable choice of conditions it is possible to obtain threads having a strength of 500-700 grams per 100 denier, and in the use of cellulose esters or ethers to obtain threads exhibiting a crystalline structure.  It is also possible to influence the lustre of the products.  If desired, the stretching may be followed by treatment with salt baths.  The swelling agent contained in the threads may be converted into vapour by heat or by vacuum treatment in order to produce "air silk," the expansion that takes place during this process producing an improvement in the extensibility of the threads.  The threads or films may be subjected to a mechanical treatment, preferably to a pressure treatment transversely to the direction of drawing, previous to, during or after the stretching or drawing operation. Additions for improving the plasticity, lustre, colour, &c. of the products, may be made to the spinning solution or to the swelling bath.

Patent JP-S5593035-A (JP)
Title: Detector for shape of strip
Inventor: ISHIMOTO MASAKI
IPC: B21B38/02
Filed: 1979-01-08
Abstract: PURPOSE:To detect the shape of a strip with efficiency and high precision by continuously measuring the thermal expansion of a split roller and then by correcting the shape detection value of the strip. CONSTITUTION:Split roller 1 rotates through spring 2 together with shaft 3. Shape displacement sensor 6 is fitted in load direction Y-Y of strip S, thermal expansion detection sensor 19 is also fitted to frame 7 in direction X-X perpendicular to it. When roller 1 expands thermally, sensor 19 detects its value and a corrector corrects the shape displacement output of sensor 6 to extract only a shape displacement output. This output is processed to obtain a shape signal and the shape corrections of strip S are made. As a result, an influence of the thermal expansion of the split roller can adequately be corrected, so that the correction display of the shape can be provided with extremely-high accuracy.

Title: Horizontal dynamic focusing circuit
Inventor: OGINO MASANORI
IPC: H04N3/26
Filed: 1989-01-06
Abstract: PURPOSE:To minimize required power by serially connecting a capacitor having a specific value to a focusing coil and generating voltage having polarity to offset the amplitude of the voltage at both terminals of the focusing coil in a horizontal blanking period at both terminals of this capacitor. CONSTITUTION:A capacitor 20 is serially connected to a focusing coil 4, and a capacitance value C of this capacitor 20 is selected so that the value can almost satisfy the relation of C=(Ts, Tr)/6L (Ts: the time of a horizontal scanning period corresponding to an upper limit horizontal scanning frequency, Tr: the time of the horizontal blanking period, L: the inductance value of the focusing coil 4). Further, the voltage having the polarity to offset the amplitude of the voltage at both the terminals of the focusing coil 4 in the horizontal blanking period is generated at both the terminals of the capacitor 20. Consequently, the amplitude of voltage to be generated at both terminals of a series circuit composed of the capacitor 20 and the focusing coil 4 can be minimized. Thus, the required power can be minimized.

Title: Operation display device
Inventor: YOSHIDA MINORU
IPC: G06F3/041
Filed: 1987-01-07
Abstract: PURPOSE:To properly always operate a plant by providing a switch means and switching a touch screen into an alternative operation display means automatically even at a fault and bringing the touch screen again in use when the function of the touch screen is recovered. CONSTITUTION:If a fault takes place in the touch screen 7, an operation command switch section 46 switches a switch 45 into a backup switch section 8, thereby disusing the touch screen and enabling the use of the backup switch section 8. Thus, the operation signal of the backup switch section 8 is outputted to a transmission line 3 via a transmission processing section 41 via a switch 45. In this case, when a switch with a light turned on is depressed, a corresponding valve is turned off, the lighting mode is switched and when a switch with its light turned off is depressed, the corresponding valve is turned on and the lighting mode is switched. Thus, a condensate demineralizer 1 is operated/ supervised by the backup switch section 8 in this way.
