Inventor: MINAMINO KATSUMI
IPC: H04N1/032
Filed: 1992-11-11
Abstract: PURPOSE:To provide a printer having a thermal head in which each designated heating element produces required quantity of heat to perform a positive printing. CONSTITUTION:A thermal head 2 in a facsimile system is provided with a plurality of heating elements KN which are heated selectively to produce a specific dot print on a recording paper.

Title: Magneto-optical recording medium
Inventor: TOKI KAORU
IPC: G11B11/10
Filed: 1986-12-16
Abstract: PURPOSE:To eliminate the need for a means for impressing an external magnetic field to the titled medium by forming a high magnetic permeability magnetic material layer, projections consisting of a 1st perpendicularly magnetized film, recording layer consisting of a 2nd perpendicularly magnetized film, and protective layer consisting of dielectrics on a substrate. CONSTITUTION:The high magnetic permeability magnetic material layer 2 is formed on the substrate 1 and the projections 3 consisting of the 1st perpendicularly magnetized film having magnetic anisotropy in the direction perpendicular to the film plane are formed at specified intervals thereon. The recording layer 4 consisting of the 2nd perpendicularly magnetized film and the protective layer 5 consisting of the dielectrics are then formed in this order thereon. The high magnetic permeability magnetic material layer 2, the projections 3 consisting of the perpendicularly magnetized film formed via an insulator layer 5 and the recording layer 4 consisting of the 2nd perpendicularly magnetized film are previously magnetized in the same perpendicular direction. The recording layer 4 is then initially magnetized in one direction and a bias magnetic field is impressed to the recording layer 4 part existing between the projections 3 in the direction opposite from the initial magnetization direction by the magnetization of the projected parts. The layer 2 acts to efficiently guide the bias magnetic field to the recording layer 4 part. Inverted magnetic domains are thus formed only by heating up the medium with a laser beam without requiring the means for impressing the external magnetic field to the medium.

Title: Terminal circuit
Inventor: TAKEDA KOJI
IPC: H03K17/16
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To reduce overshoot or undershoot, when switching the voltage level at the end of a transmission line. SOLUTION: A terminal circuit 11 has a terminal switching circuit 4 and an auxiliary switching circuit 41. When the voltage level at the end 5 of a transmission line 4 is switched from low to high, the end switching circuit 40 connects the end 5, which is connected to a ground potential at low level, to a power supply voltage Vcc corresponding to the high level but since the auxiliary switching circuit 41 temporarily connects the end 5 to the ground potential corresponding to the low level before the connection is completed, the impedance of the terminal circuit 11 is temporarily lowered. Therefore, overshoot or undershoot, which conventionally occurs when switching the voltage level, can be reduced.
