Title: Hollow fiber membrane
Inventor: BENJIYAMIN BIKUSON
IPC: D01D5/24
Filed: 1992-07-31
Abstract: PURPOSE: To obtain highly asymmetric hollow fibers useful as permselective gas separation membranes and their composite membrane by extruding a spinning dope into a gas-filled chamber maintained under reduced pressure, passing the extruded hollow fiber through a liquid bath and solidifying the extrudate. CONSTITUTION: A solution of a fiber formable polymer is extruded through a spinning mouthpiece into a vacuum chamber where a gaseous medium maintained under pressure lower than the atmospheric pressure is housed. The extrudate is thereafter passed through the liquid bath and the hollow fiber is solidified. The solidified fiber is washed and the solid highly asymmetric hollow fiber is recovered. The distance between the vacuum chamber existing between the spinning mouthpiece surface and the liquid bath is about 0.2 to about 2m. The highly asymmetric hollow fiber has a gas separation barrier layer thinner than about 1000 Å thickness. As a result, the highly asymmetric hollow fiber is usable for production of the highly asymmetric hollow fiber membrane integrally formed with a skin layer and a highly asymmetric substrate useful for production of the composite membrane.

Title: Binary coding method of picture data
Inventor: YOKOYAMA HARUHIKO
IPC: G06K9/38
Filed: 1982-12-20
Abstract: PURPOSE:To binary code a desired object and to discriminate the binary coded object from its periphery by setting a partial picture at a proper size. CONSTITUTION:The average of the picture data within a partial picture PKl is set at mKl and used as the threshold value at the center position qKl=(xK, yl) of PKl. The threshold values at the points other than {qKl; 1<=K<=m, 1<=l<= n} are decided as follows. That is, an optional point (i, j) on a picture included in P' is enclosed by four points forming an apex of a rectangle among {qKl} 1<=K<=m and 1<=l<=n. The threshold values ti and j at the point (i, j) are defined by an interpolation equation. A point (i', j') of P' closest to the point (i, j) is selected for the point (i, j) belonging to P'', and the threshold values ti' and j' of the point (i', j') obtained by an interpolation equation are defined as the threshold value tij of the (i, j). These threshold values thus obtained vary consecutively on a picture. The picture data value at the point (i, j) is defined as dij to obtain the binary picture data bij.

Title: Photographic printing device
Inventor: KOGANE MIKIO
IPC: G03B27/32
Filed: 1984-10-25
Abstract: PURPOSE:To control the breadthwise movement of photographic paper even when photographic paper of different width size is sent by moving a guide roller and the flange of a take-up spool axially according to the width of the supplied photographic paper. CONSTITUTION:A rotating shaft 70 is rotated by the rotation of a motor through a timing belt 76 and the rotation of a male screw 72 moves a driving shaft 58 axially together with a coupling plate 64. Consequently, a disk 44 moves axially through a slide bearing 62 together with the driving shaft 58. Consequently, the roller 48 of the disk 44 moves the flange 54 in the axial direction of a winding drum 20 to move the flange 54 according to the width size of the roll part 24A of the photographic paper loaded around the winding drum 20. Therefore, even when photographic paper of different width size is fed, its breadthwise movement is controlled properly.

Title: Thermal recording method
Inventor: KANEKO AKINARI
IPC: B41J2/36
Filed: 1986-09-22
Abstract: PURPOSE:To obtain high quality printing by well performing heating control without making a circuit complicated, by changing an applying pulse width corresponding to the number of heat generating elements to which a current is simultaneously supplied with due regard to the past heat history of each heat generating element. CONSTITUTION:The number of heat generating elements 2(dots) to which a pulse is supplied (the number of heat generating dots to which a current is simultaneously supplied) in a head 20 are counted and a pulse width is determined according to a range to which the number of the heat generating dots belong. Further, the pulse width is determined with due regard even to the heat hisotry of the previous time [the elements generated heat (were in an ON-state) or were in an OFF-state at the previous time]. Since the pulse width is determined according to the range to which the number of the heat generating dots belong, the constitution of the control circuit for driving the head or circuit planning becomes simple. Furthermore, the pulse width may be made short by definite quantity when the number of the elements to which a current is simultaneously supplied exceed a definite number and may be made long by definite quantity when the number of said elements fall below a separate certain definite number. As a result, since the pulse width is controlled corresponding to the number of the heat generating dots, said pulse width can be adjusted so that not only the printing at that time but also the next printing can be well performed and the heating control of the elements can be fully performed.

Filed: 1988-09-09
Abstract: PURPOSE:To improve the utilization factor of a light beam from a light source by arranging an opening type fluorescent tube whose opening part is shaped like a convex lens on an optical axis of a cylindrical lens. CONSTITUTION:The opening type fluorescent tube 1 is arranged on one end part of a box body 2, and a cylindrical lens 5 is arranged on a position separated therefrom by a prescribed distance. By forming an opening part of the fluorescent tube 1 in a shape of a convex lens, a light beam emitted from the opening part is condensed and more emitted light beams are made incident on the lens 5. By such a constitution, a light beam 8-1 which transmits through the lens 5 becomes roughly parallel rays. The light beam 8-1 is reflected by semi- transmissive mirrors 6-1 - 6-4 and a total reflection mirror 7 arranged on an optical axis of the lens 5. These reflected light beams 9-1 - 9-5 are all quasi- parallel rays and its intensity is equal, and to a transmissive display panel 3, uniform quasi-parallel rays are made incident extending over the whole surface. Therefore, an emitted light beam 10 from the panel 3 becomes an optical component having good contrast to a liquid crystal panel.

Title: Thermal hysteresis sensor
Inventor: KATO TSUTOMU
IPC: C04B35/64
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To precisely measure an indicated temperature in a wide range of high temperature area under non-oxidizing atmosphere by manufacturing a non-baked body in which a specified wt.% by inner ratio of Y2 O3 is added to AlN as base material by CIP(cold isostatic pressurization) molding, and setting its density within a specified range. SOLUTION: In this thermal hysteresis sensor, a non-baked compact in which about 4-5 wt.% by inner ratio of Y2 O3 is added to AlN as base material is manufactured by CIP molding. Further, the density is preferably set within the range of about 1.9-2.3 g/cm<3> . The sintering characteristic of the manufactured compact is significantly influenced by the uniformity of the mixing state of AlN powder with Y2 O3 and the constancy of form, surface activity and grain size distribution of each powder. Therefore, for a mixed powder obtained by pulverizing mixing treatment such as ball mill treatment, it is important to perform the form observation, specific surface area measurement, and grain size distribution measurement of the powder in the same manner as the starting material powdery to confirm whether the results satisfy prescribed conditions or not.

Title: Radiation irradiation catheter
Inventor: MAEDA HIROMI
IPC: A61N5/10
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To prevent a radiation wire from coming out into blood vessel though the guide wire can go out into a blood vessel over the tip end part by making the guide wire and the radiation wire pass through the same lumen and the diameter of the lumen reduced around the tip end part and specifying the size of the smallest diameter part. SOLUTION: This catheter 12 comprises a shaft with a lumen and a manifold 27. The diameter of the tip end part of the shaft is reduced toward the distal end side. The shaft comprises the distal shaft 14 and the proximal shaft 15. The lumen of the haft is commonly used for passing the guide wire 11 and the radiation wire 7. The smallest inner diameter around the tip end part of the lumen is set at a size larger than the outer diameter of the guide wire 11 but smaller than the outer diameter of the radiation wire 7. Thus the guide wire 11 can come into a blood vessel over the tip end part but the radiation wire 7 cannot come into the blood vessel because motion of the radiation wire 7 is obstructed around the tip end of the lumen.
