Title: Magnetic bearing
Inventor: HAGIWARA SHIROU
IPC: F16C32/04
Filed: 1979-10-29
Abstract: PURPOSE: To obtain buoyance for a rotor by a repulsion produced as the rotor turns by probiding a closed loop coil-provided stator at an intersecting position between the rotor with a permanent magnet arranged on the same circumference and magnetic flux of the permanent magnet.  
     CONSTITUTION: When a permanent magnet 22 provided on a rotor 21 moves on a closed loop coil 25 at a given speed, a magnetic flux is changed traversally with the closed loop coil 25, whereupon inducing an electric current in the coil 25. Then, a repulsion is exerted on the magnet 22 by a magnetic flux produced by the electric current. Since conical faces 21C, 21D, 23C, and 23D are formed on the rotor 21 and the stator 13, the repulsion exerting on the rotor 21 works vertically on the conical faces 21C and 21D, so that the rotor 21 is magnetically bouyed in the thrust and radial directions.

Title: Check valve for ink jet
Inventor: TSUZUKI MITSUO
IPC: B41J2/175
Filed: 1981-09-04
Abstract: PURPOSE:To improve the rate of good valve assembly by eliminating the necessity for raising the dimensional accuracy of valve elements and the positional accuracy of assemblage by forming a dike-like protruded part on the surface of either a valve or a valve seat at their overlapped part. CONSTITUTION:Valve members of a check valve are composed of a disk-like valve 103, an arm 104 supporting thereof and a circular ring like fixing part 105. On one side of the disk-like valve 103, a dike-like protruded part 202 is formed. As pressure acts from the side of an ink passage 101, the valve 103 is pushed up, and ink flows out through a gap between the valve 103 and a valve seat 102. As pressure acts in the inverse direction, the protruded part 202 on the valve 103 contacts with the valve seat 102 and shuts  off the ink flow. At the time of flowing of ink, the gap between the dike-like protruded part 202 and the valve seat 102 is especially narrower than that between the valve 103 and the valve seat 102, therefore, the flow of ink is substantially determined by the resistance of the gap between the protruded part 202 and the valve seat 102. If the shape and dimension of the protruded part 202 are kept constant, the variation of the valve characteristics becomes smaller even if the dimensions of the valve 103 and the passage 102 of the valve seat 102 are varied and the overlapped position of the valve 103 and the passage 101 is deviated.

Title: Constant-amplifude oscillating circuit
Inventor: HIRANO MASAHIRO
IPC: H03B5/08
Filed: 1980-10-06
Abstract: PURPOSE:To stabilize oscillation amplitude with simple circuit constitution by controlling the oscillation amplitude by a DC voltage which corresponds to the difference of the rectified voltage of an oscillation output and a reference voltage. CONSTITUTION:The AC component of an oscillation output VC generated at the output terminal 2 of an oscillating circuit OS is inputted to a half-wave rectifying circuit FD through a capacitor C2 to obtain the half-wave rectified voltage VD of the AC component of the VC at the output 4 of the circuit FD. A reference voltage generating circuit RV, on the other hand, generates a reference voltage VZ, and the voltage VD and a voltage having the opposite polarity to it are led to the amplifier U2 of a differential integral network DI, so that the integral output E1 of the VD and VZ appears at its output 7. The output E1 is fed back to the base circuit of the transistor Q of the circuit OS. In this circuit constitution, the rectification output VD varies in the positive direction as the oscillation amplitude VC increases, so that the output E1 of the circuit DI varies in the negative direction. Consequently, the oscillation amplitude decreases automatically and stabilizes itself with a prescribed value.

IPC: A61K47/30
Filed: 1979-10-30
Abstract: PURPOSE: An enteric coating composition that is composed of a surfactant, a triglyceride or polyvinly alcohol and a polyanion high polymer, thus showing good operability and high quality.  
     CONSTITUTION: An enteric coating composition for an aqueous solvent is obtained from a surfactant such as a nonionic surfactant of polyoxyethylene sorbitol fatty acid ester, a trigylceride of middle-size chain fatty acid and/or polyvinyl alcohol and a polyanion high polymer such as hydroxypropylmethylcellulose phthalate. Hrdroxypropylmethylcellulose is an enteric high polymer but hard soluble in water, therefore, coating is diffucult by the use of an aqueous solven. However, the combination use with a surfactant and a triglyceride and/or polyvinyl alcohol makes the hydroxypropylmethylcellulose water-soluble to facilitate the coating operation.
