Title: Carrier driver for typewriter of the like
Inventor: FUJIMURA NOBUHIKO
IPC: B41J19/20
Filed: 1985-02-28
Abstract: PURPOSE:To alleviate vibration of a carrier due to stepping rotation of a stepping motor, smoothly move the carrier particularly when moving the carrier over a long distance and contrive a higher speed, by connecting a flywheel to an output shaft of a stepping motor. CONSTITUTION:As the stepping motor 11 is rotated forward or reversely, a capstan 18 is rotated forward or reversely, and one of two wires 20, 21 is taken up by the capstan 18, while the other is paid out. As a result, the carrier 1 is automatically slidden leftward or rightward as the motor 11 is rotated forward or reversely. Since the flywheel 11b is fixed to the output shaft 11a of the motor 11, in the case of continuous movement (e.g., tabulation) of the carrier 1, the vibration due to stepping rotation of the motor 11 is canceled by the flywheel 11b. Accordingly, the carrier 1 is smoothly moved continuously, and a higher positioning accuracy and a higher speed can be contrived.

Abstract: PURPOSE:To suppress the generation of bubbles when a liquid sample is flowed into a flow cell, by forming a taper on the inside wall of a leading-in tube to increase gradually the inside diameter of an inlet-side passage toward the side of a light flux transmitting part. CONSTITUTION:A light flux transmitting part which is so formed into a conical shape that the inside diameter is increased gradually is provided in a flow cell main body 1, and the light is incident from the side of a smaller inside diameter toward the side of a larger inside diameter. The inside diameter in the side of the light flux transmitting part 22 on an inlet-side passage 2 formed in the cell main body 1 is equal to the small inside diameter of the light flux transmitting part 22. The inlet-side passage 2 is so tapered that the diameter is larger in the down stream of a liquid, and the side of the inlet-side passage 2 brought into contact with the end part of a leading-in tube 4 has the same inside diameter as the leading-in tube 4.

Title: Magneto-optical disk
Inventor: MATSUDA NOBUHIDE
IPC: G11B11/105
Filed: 1988-02-19
Abstract: PURPOSE:To give a sufficient magnetic field to a recording layer with a small external magnetic field by providing a 2nd magnetic layer having strong coercive force for recording through a 1st magnetic layer having weak coercive force. CONSTITUTION:The 1st magnetic layer 7 which is provided for increasing a magnetic effect is provided between the 2nd magnetic layer 1 for recording and a disk base plate 2. The coercive force of the 1st magnetic layer 7 is made weaker so that no magnetization can remain and a magnetic material having high susceptibility is used for the magnetic layer 7 so that the magnetic effect can be increased. Therefore, the magnetic flux produced from an electromagnet 5 returns to the electromagnet 5 through the 1st magnetic layer 7 and the magnetic flux does not diffuse in a recording area 6. Thus a high magnetic flux density is obtained in the recording area 6 and a highly efficient magnetic bias is obtained. Accordingly, a sufficient magnetic bias can be obtained with a small electromagnet or a less driving current.

Filed: 1988-02-19
Abstract: PURPOSE:To improve durability by using a styrene/acrylic copolymer formed by using an acrylic acid component having a hydrophilic COOH group in a polystyrene resin having a high modulus of elasticity as the binder component of a magnetic layer. CONSTITUTION:The styrene/acrylic acid copolymer used as the binder component of the magnetic layer is obtd. by introducing the acrylic acid component having the hydrophilic COOH group in the polystyrene resin having the high modulus of elasticity. Since the binder component has the hydrophilic COOH group in the molecule, said component has good affinity to the magnetic powder and the COOH group is adsorbed well on the surface of the magnetic powder. The COOH group, therefore, is adsorbed well on the surface of the magnetic powder if such binder component is used. The dispersibility of the magnetic powder is thereby improved and the electromagnetic conversion characteristics is improved. The strength of the magnetic layer is simultaneously intensified by the polystyrene resin having the high modulus of elasticity. The highly elastic magnetic layer is thereby obtd. and the durability is improved.
