Title: Microporous film with increased pore density and its manufacture
Inventor: HARORUDO MANRII FUITSUSHIYAA
IPC: C08J5/18
Filed: 1989-05-12
Abstract: Disclosed are a process for forming an open-celled microporous membrane (e.g., in film or fiber form) and a novel microporous membrane formed thereby. The process generally includes sequential cold and hot stretching operations, whereby the cold stretching operation is preferably accomplished in a plurality of discrete cold stretching steps. In this regard, the total cold stretch extension is of greater than about 30 percent, and advantageously greater than about 40 percent based upon the initial unstretched length of the nonporous precursor, with this total cold stretch ratio being distributed among a plurality of discrete cold stretching steps. The novel membranes of this invention are characterized by decreased pore sizes and increased pore densities. For example, the membranes of this invention will have an average pore radius as determined by mercury porosimetry of less than about .040 micron. The membranes of this invention, moreover, exhibit a distinctive "bluish" color hue (i.e., a Macbeth Coloreye TM  b* value of less than about -10 as determined by placing a single ply sample of the membrane against a black background).

Inventor: NAGATA TERUKAJI
IPC: A23K1/00
Filed: 1990-05-09
Abstract: PURPOSE:To remove a bad smell of fish and egg by action of chlorophyll and to obtain fowl meat and fowl eggs suitable for fowl meat dish free from a fishy smelling of fish, by feeding to domestic fowls a lactic acid fermentation feed prepared by subjecting a green feed to lactic acid fermentation instead of animal protein such as fish or fish meal. CONSTITUTION:A raw green feed or a dried green feed is blended with grains such as rice bran, soybean, soybean cake, wheat, maize or bean-curd refuse and subjected to lactic acid fermentation to produce a lactic acid fermentation feed. Animal protein such as fish or fish meal is not fed to domestic fowls. The lactic acid fermentation feed is fed to domestic fowls as much as possible so that a bad smell of meat and egg is removed by action of chlorophyll and a bad smell of fowl meat and fowl egg derived from feed is eliminated by masking action of lactic acid fermentation. Grass, vegetable, white Dutch clover, etc., are used as the green feed.

Inventor: IKEDA TOSHIO
IPC: E02F9/22
Filed: 1983-06-28
Abstract: PURPOSE:To exactly compensate for the flow rate of fluid all the time regardless of the variation in the loads of other actuators for the actuator for a rotator by providing a pressure compensation valve capable of alternately controlling both pressure control sections for throttling and diversion. CONSTITUTION:A pressure compensation valve 10 capable of alternately controlling a control section Y for throttling pressure and a control section Z for diversion pressure is provided on the discharge side of a fluid pump 1. An actuator 3 for a slewing body is connected through a flow direction control valve 30 to the rear position of the control section Y, and the rear position of a flow regulating and varying orifice 40 is led to the spring side. Other actuators 4 and 4' are connected through direction control valves 5 and 5' to the rear position of the control section Z. By the compensation valve 10, both the control sections Y and Z are alternately controlled for mutual variations of loads W1 and W2, and thereby compensation for the flow rate to the actuator 3 is preferentially made. Since the speed of the actuator 3 is not varied even when loads are changed during the slewing period of the slewing body of a power shovel, the operability of the construction machine is excellent and the possibility of occurrence of hazard during the operations is reduced.

Title: Ion exchange resin and desalination device filled with the same
Inventor: SUDO SHIZUKA
IPC: C08L101/00
Filed: 1994-05-31
Abstract: PURPOSE:To obtain an ion exchange resin having large clad capturing ability and small in impurity eluting quantity. CONSTITUTION:The ion exchange resin is synthesized by using diallyl benzene having longer normal chain than that of the divinyl benzene as a cross-linking agent without changing the cross-linking degree of a cation exchange resin and an anion exchange resin. Since the clad removing ability is improved by increasing micropore diameter with lower cross-linking, the micropore diameter is increased by using the diallyl benzene in place of divinyl benzene. And the ion exchange resin has a swelling structure as a whole and is improved in clad removing ability even when the cross-linking degree is not decreased.

Title: Production of magnetic disk medium
Inventor: ASANOME SATORU
IPC: G11B5/84
Filed: 1989-05-10
Abstract: PURPOSE:To eliminate an influence of scratches on servo tracks by polishing a magnetic disk medium while rotating the disk with a rotation axis which is eccentric to the center of the disk. CONSTITUTION:The disk is polished while rotated around the axis at an eccentric position 24. Even when flaws are caused during polishing, a flaw 18a traces an arc with the center at the position 24. When the medium 8 is mounted in a magnetic disk device, the medium is fixed to a spindle and rotated around the center 9. A servo track 19a written in the medium is concentrical to the disk. Therefore, the flaw 18a and the servo track 19a cross once at a point 26 in a very short length and time. Thereby, the flaw 18a gives almost no influence on the servo track 19a.

Abstract: PURPOSE:To manufacture the prescribed welding pipe with good yield and high efficiency by continuously welding the contact both side end parts where a strip metal is formed in a tubular shape, immediately performing a pipe drawing with a roller die at the reduction rate or more of a fixed cross section and winding it in a coil shape, if necessary. CONSTITUTION:The straightened metal strip of a mild steel or stainless steel is formed in a tubular shape with a forming machine and made a seamed pipe by cooling the contact both side end parts thereof with the continuous welding by high frequency welding, TIG welding, etc. This seamed pipe is drawn at >=10% cross section reduction rate causing no deflection on the pipe inner face shape by the roller die immediately and the pipe drawing is repeated until the prescribed dimension. The pipe drawing efficiency is not good in case of this cross section reduction rate being <=10%. It is formed in a coil shape by winding in a coil shape if necessary, and cut thereafter in the prescribed dimension. There is no material waste, the yield is improved and the production efficiency is increased with a through continuous process.

Title: Television picture receiver
Inventor: TAKAHASHI KOUJI
IPC: H04N5/63
Filed: 1977-10-05
Abstract: PURPOSE: To avoid application of the acceleration voltage before the cathode temperature is raised sufficiently, by applying the voltage to the heater of the picture tube simultaneously with throw-in of the power switch and applying the voltage to other electrodes of the picture tube with a fixed time delay.  
     CONSTITUTION: When the power switch is thrown in, power supply +B of the circuit can be obtained immediately to start operation of the horizontal oscillator circuit and horizontal driving transistor Tr5. And the heater voltage is supplied to heater 2 of the picture tube from horizontal driving transformer 3. However, Tr9 is turned on since Tr8 is still off with no operation of horizontal output Tr6, and only the heater voltage is applied to the picture tube. Then voltage +B charges capacitor 12 via resistance R, so the potential at point (a) is increased gradually. Thus, Tr8 is turned on and Tr6 has output to supply the voltage to picture tube 1 from flyback transformer 4. As a result, the application of the acceleration voltage before the cathode temperature is raised up sufficiently can be avoided
