Filed: 1980-03-27
Abstract: PURPOSE: To make magnetic flux passing through an armature constant without regard to a temperature change and obtain a head having stable printing characteristics by forming a magnetic path bypassing the magnetic flux of a permanent magnet by a magnetic material, magnetic reluctance thereof increases with a temperature rise.  
     CONSTITUTION: The magnetic flux of a permanent magnet 3 passes through the second yoke plate 5, a spacer 6, a flat spring 7, the third yoke plate 10, an armature 8, a core 2 and the first yoke plate 1 under a condition that a demagnetizing coil 4 is not excited, the armature 8 is sucked to the core 2 and the flat spring 7 is deviated, but a magnetic field of the permanent magnet 3 is denied when exciting the demagnetizing coil 4, and printing is conducted by means of a wire 9 by the righting moment of the flat spring 7. When the magnetization of the permanent magnet 3 decreases due to heat generation being accompanied by the increase of printing speed, the magnetic reluctance of a yoke 12 for bypass also augments, and magnetic flux passing through the yoke 12 diminishes, thus resulting in the slight variation of magnetic flux passing through the armature 8, then maintaining stable drive.

Title: Surface modifier for resin additive
Inventor: MASAOKA KIMIYA
IPC: C09C3/08
Filed: 1986-02-24
Abstract: PURPOSE:To obtain a surface modifier which can allow a resin-insoluble powder to disperse homogeneously in the resin and can make cells of a resin foam uniform, by using a specified cyclic carbonate as a component. CONSTITUTION:A surface modifier for a resin additive, containing a cyclic carbonate of the formula (wherein R1, R2, R3, R4 and R6 are each H or a 1-3C alkyl). Among said cyclic carbonates, 1-isopropyl-2,2-dimethyl-1,3-propylene carbonate of the formula (wherein R1, R2 and R6 are H, R3 and R4 are methyl, and R5 is isopropyl) is particularly desirable. The cyclic carbonate resin used is highly compatible with a variety of resins. It can be adsorbed on the surfaces of various fine powders and has a function of disintegrating agglomerates. Therefore, when a powdery resin additive is surface-modified with the modifier and then added to a resin, it does not form agglomerates in the resin and can be dispersed homogeneously with markedly improved workability, so that the appearance and strength of the formulated resin are not adversely affected.
