Title: Solid drawing material
Inventor: TANGE MAKOTO
IPC: A61Q1/04
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a solid drawing material which has a high density and strengths and gives a light smooth feeling in drawing by adding a melamine/ cyanuric acid adduct to a drawing material prepared by molding a composition essentially consisting of a colorant. SOLUTION: It is desirable to add 1-30 wt.% melamine/cyanuric acid adduct. The melamine/cyanuric acid adduct has cleavability because it consists of layers each of which consists of melamine molecules and cyanuric molecules arranged in a plane by hydrogen bonding and which are superposed upon each other by relatively weak bonds and therefore are peeled from each other relatively easily. Therefore, it can facilitate the peel of the particles of the colorant, etc., from the drawing material and to promote its wear to improve the density. Further, the hydrogen bonds among the melamine molecules and the cyanuric acid molecules in each layer of the adduct are strong, so that it exhibits high bending strength against bending force acting on the solid drawing agent.  Furthermore, the adduct, in virtue of its molecular structure, has a good affinity for other organic components of the solid drawing agent, can uniformly penetrate among the materials such as a colorant, and can toughen the solid drawing material because of its role of binding the respective materials as a whole.

Title: Magnetic core for power source line filter
Inventor: YOSHIZAWA KATSUTO
IPC: H01F3/10
Filed: 1983-06-29
Abstract: PURPOSE:To improve high frequency characteristics against noise and characteristics against high voltage pulse by composing a line filter core of an amorphous core and a ferrite core. CONSTITUTION:A ferrite core is hard to saturate but an absolute value of its permeability drops rapidly in a high frequency region. On the other hand, an amorphoous core is easy to saturate but its permeability does not drop rapidly. Therefore, if a line filter core is composed of a ferrite core and an amorphous core which are magnetically connected in parallel, frequency characteristics are improved by the amorphous core and characteristics against high voltage pulse are improved by the ferrite core. When an effective area of the amorphous core is 30% of the whole area and the thickness of the amorphous is 25mum or less and the absolute value of its permeability at 1MHz is 2,000 or above, the excellent characteristics can be obtained.

Abstract: PURPOSE:To make it possible to obtain density free from fogging and resolving power, in a toner system image recording apparatus, by intensifying the magnetic field due to a magnet at the time of the non-application of recording voltage to a recording electrode as compared with that at the time of the application thereof by a pulse magnetic field generation means. CONSTITUTION:When no signal voltage is applied to a recording electrode 7, toner T receives force in a D-direction by the movement of a recording medium 1 in an A-direction but a magnet 7 flows a current to a coil 14 from a pulse power source 12 so that the directional magnetic flux intensifying the magnetic flux at the leading end of the electrode is generated from a magnetic material 13 and magnetical restricting force is acted on the toner T to prevent the unnecessary toner T from flowing out to the downstream side of the electrode 7 and the fogging of an image is prevented. At the time of the application of signal voltage, no current is flowed to the coil 14 and the restricting force to the toner T at the leading end of the recording electrode 7 is weakened and, at this time, the toner T is adhered to the recording medium 1 by the voltage applied to the recording electrode 7 from a character signal generator and a sharp image is obtained.
