Abstract: PURPOSE:To prevent the reduction of a thermal efficiency of a fixer by providing a good-heat conductive pipe connected to the outside of side plates at the both ends thereof, a depressing means feeding paper toward a printing device in conjunction with the pipe, and an air blasting means feeding an air outside the side plate to the inside of the pipe. CONSTITUTION:An image is heated and fixed by a fixer 17, and paper remaining in a high temperature state is discharged by discharge rollers 17a, 17b. There after, the paper is clamped between a pressure roller 3 and a pipe 4 and fed toward a printing device 2 in the state that the full width of the paper is brought into pressure contact with the peripheral surface of the pipe 4. During the feeding, a relatively low-temperature air existing outside a side plate 1b is fed into the pipe 4 by a suction fan 6, whereby the unprinted paper is cooled through the good heat-conductive pipe 4 made of aluminum. In this manner, such a failure in printing that the high temperature of the paper causes a part of an ink ribbon other than a printing pattern to melt, to be transferred to the paper is prevented. In addition, the fixer 17 is prevented from being reduced in thermal efficiency.

Abstract: PURPOSE:To obtain the suppressing effect of a ringing by making a ringing control means to be non-linear, and to avoid the problem of the blurring of a boundary, or the thickness of a line. CONSTITUTION:In an adaptive ringing controller which is equipped with a ringing detecting circuit 3 which detects the part of the generation of a ringing, and a ringing control circuit 2, and which controls the suppressing amount of the ringing suppressing circuit 2 based on the detected result of the ringing detecting circuit 3, the circuit of an amplitude non-linear characteristic whose frequency characteristic is changed according the amplitude of an input signal is used as the ringing control circuit 2.

Title: Vertical magnetic recording medium
Inventor: KOBAYASHI KAZUO
IPC: G11B5/66
Filed: 1981-12-29
Abstract: PURPOSE:To realize high density and a high output for a vertical magnetic recording medium,  by providing a vertical magnetic anisotropic magnetic layer of magnetic wall shift type on the  back of a vertical magnetic anisotropic magnetic layer. CONSTITUTION:A vertical magnetic anisotropic magnetic layer 3 of magnetic wall shift type is  laminated on a vertical magnetic anisotropic magnetic layer 2. The coercive force of the layer  2 is smaller than that of the layer 3, and the saturated magnetization of the layer 2 is set  larger than the residual magnetization of the layer 3 along with a larger anisotropic magnetic  field. The magnetic domain width (a) of the layer 2 in a state of demagnetization decreases as the saturated magnetism MS of the magnetic layer increases and then has a reduction with  the decrement of the anisotropic constant Ku. When the writing is carried out to such a recording medium, the width (a) of the layer 3 is equalized to that of the layer 2. This width  (a) can be set at a small value, and therefore, the recording denity is increased. Furthermore,  a magnetic wall is shifted easily by a writing magnetic field to the layer 3 with a relation of  the above-mentioned coercive force, and at the same time the anisotropic magnetic field of the  layer 2 is not tilted by that of the layer 3 in relation to the anisotropic magnetic field. The  surface magnetization of the layer 3 is increased more than the conventional one with an  increment of output since the magnetization of the layer 2 is produced in response to the magnetization of the layer 3.
