Title: Stretching method of polyester film
Inventor: NAGASAWA TSUGIO
IPC: B29K67/00
Filed: 1984-06-08
Abstract: PURPOSE:To obtain a longitudinal uniaxial stretched film excellent in low-speed transverse stretching properties by a method wherein the ends of a film being stretched between draw rolls are stretched longitudinally uniaxially as they are heated more strongly than the part excluding end parts to equalize the distribution of the double refraction ratio in a width direction of the film. CONSTITUTION:First, after a film is stretched in a longitudinal uniaxial direction the double refraction profile of the film is measured in a TD direction. The double refraction profile in a TD direction of the stretching polyester film is equalized as possible by controlling the heating grade and the end parts of polyester film are heated between two draw rolls 1, 1 more strongly than the parts excluding the end parts. Threafter, said film 4 is taken up by the second roll at 40 deg.C or lower and stretched. In order to heat strongly the ends of the film, for example, a stopping plate 5 is equipped on the infrared heater 3 and the infrared output can be changed by the aperture of the stopping plate 5 in the width direction of the film.

Abstract: PROBLEM TO BE SOLVED: To prepare a further precise model to be controlled without stopping identification by inputting an input signal which does not violate previously decided constraint as much as possible in a method for identifying an object to be controlled for estimating a model to be controlled from an inputs signal and an output signal. SOLUTION: The characteristics of an object to be controlled are estimated from input and output data until the present point of time by a plant characteristic estimating part 3, and a future plant output is predicted by using a plant model and a previously prepared plant model for a disturbance input by a future plant output predicting part 4.

Title: Flexible magnetic disk device
Inventor: HIRAO HIDEO
IPC: G11B5/596
Filed: 1980-08-28
Abstract: PURPOSE:To realize the tracking with high density of track, high reliability and high accuracy through a simple constitution, by giving a fine adjustment to the position of a head part so as to obtain a coincidence between the reading outputs of two pairs of erasing heads. CONSTITUTION:A head part consisting of a write/read head plus two pairs of erasing heads shifts according to a direction indicating signal 29 passed through a gate 25 and by the number of pulses generated from a pulse generating circuit 16. Thus the output of a counter 17 is inverted to a high level. Then a fine adjustment pulse generating circuit 18 is made active, and at the same time a gate 26 is opened. Thus the shifting direction of the head shifting part is controlled via a comparator 21. The comparator 21 compares the read-out outputs produced by two pairs of erasing heads and produces a direction indicating output of either a high or low level. Thus the fine shift of the head part is continuously controlled in accordance with the pulse a generator 18 and until the output of the comparator 21 becomes zero. As a result, the tracking is controlled assuredly with a simple constitution to ensure the tracking with no effect of a malformation, etc. caused by the temperature change of a high- density track plus high reliability and high accuracy.

IPC: G01C17/28
Filed: 1993-04-23
Abstract: PURPOSE:To correct the magnetization of an on-vehicle geomagnetic azimuth sensor without turning a vehicle by using the output of an azimuth detecting element and a magnetism detecting element of both points, of which azimuth is relatively accurate, for computing. CONSTITUTION:Output in well-known two directions (X1, Y1), (X2, Y2) are obtained by a magnetism detecting element, which is offset to a circle 2 by the magnetization. Since these two directions are already known, for example, angles theta1, theta2 to the Y-axis, which coincides with North, are already known, and a tangent value can be computed previously. At this stage, an assumption that straight lines L1, L2 are draw from P1, P2 to the offset position (X0, Y0) is performed, simultaneous equations of the straight line are expressed as Y0-Y1=a1(X0-X1)Y0--Y2=a2(X0-X2), wherein a1, a2 mean tangent values of theta1, theta2. A solution of these equations is an intersection of the straight lines L1 and L2, namely, the offset position (X0, Y0). Correction is thereby performed.

Title: Cold trap
Inventor: TOYODA TAKAHIRO
IPC: G21C19/313
Filed: 1979-09-19
Abstract: PURPOSE:To prevent the porous storing body of a cold trap for purifying molten metal or other use from being clogged locally near the inflow holes by storing packings in the storing body while leaving a space and placing members for supporting the packings in the space. CONSTITUTION:Packings 11A are stored in porous storing body 13A while leaving space 14. Many inflow holes 12A are made in body 13A by plastic working, and support members 15 corresponding to holes 12A are bent to the packing 11A side to support packings 11A. When sodium or the like contg. impurities flow into holes 12A from the outside of body 13A, the passages are narrowed, and then the flows are diffused in space 14 and enter the whole region of packings 11A. By this mechanism local clogging near holes 12A is prevented to elongate the life of this cold trap.
