Title: Overheating preventive method and device for thermal head
Inventor: INOUE HAJIME
IPC: B41J2/375
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent overheating of each heat generating element of a thermal head. SOLUTION: This counter 27 counts an output time of an 'L' original enable signal outputted from a thermal head control part 25, and outputs an 'L' when the counted time is within a standard time. An enable signal with the same pulse width as the original enable signal is outputted from an OR gate 28.

At the time, an 'H' stopping signal is outputted from the counter 27 so that an enable signal is not outputted from the OR gate 28. Thereby, electric power supply to a heat generating element is stopped in a thermal head 14.

Title: Magneto-optical disk device
Inventor: HIRONO MASATOSHI
IPC: G11B11/105
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent the S/N ratio of a signal in recording or reproducing desired information from depending on the direction of a rotary mirror installed on the rotary axial center of a swing arm, by nearly circularly polarizing a laser beam that enters from a fixed optical system to a movable optical system having the swing arm. SOLUTION: A fixed optical system 7 makes a parallel beam, with a collimator lens 19, from a linearly polarized laser beam generated by a laser light source 20, forming a desired cross sectional shape, e.g. a circle, with a prism 18, circularly polarizing the beam with a λ/4 wavelength plate 12, and making it enter a rotary mirror 6 in a movable optical system 21 through a mirror 16. The circularly polarized laser beam is symmetrical in the polarizing characteristics around the optical axis and, when reflected by a rotary mirror 6 rotating around the optical axis, its reflectance is not dependent on the direction of the rotary mirror 6. As a result, in recording or reproducing desired information on a magneto-optical disk 8, the S/N ratio of a signal is free from dependence on the direction of the rotary mirror 6, permitting a stable operation.
