Title: Thin-film thermal head
Inventor: TASHIRO MITSUHIKO
IPC: B41J2/335
Filed: 1980-04-30
Abstract: PURPOSE: To obtain the stable and highly reliable thin-film thermal head by providing a heating resistor film and an electrode film on an insulated substrate and by providing further on the surface thereof an anti-abrasive protection film prepared by laminating specified layers.  
     CONSTITUTION: On the insulated substrate 1 are provided the heating resistor film 2 of Ta-SiO system and the electrode films 3a and 3b making electrification to the former. Further on the surface thereof is provided the anti-abrasive protection film prepared by connecting A Ta 2 O 5 -Si mixture film or a Ta-SiO 2  mixture film as the 1st-layer protection film 4 thereon and further connecting a Ta 2 O 5  film as the 2nd-layer protection film 5 on the film 4. Since the 1st-layer protection film 4 as a buffer layer for thermal strain is connected directly on the heating resistor and the electrodes, it is required to guarantee insulation resistance of a fixed level or higher between the electrodes. The specific resistance desired for the 1st-layer protection film 4 varies based on the thickness of the film, the area of connection thereof and the distance between the electrodes, and generally, the specific resistance ten times as large as that of the heating resistor is required.

Title: Wire dot head
Inventor: ARA YOJI
IPC: B41J2/235
Filed: 1985-03-23
Abstract: PURPOSE:To provide a small wire dot head generating noise during operation by making a holder structurally integrated in sections through a vibration damping material and preventing the resonance of the holder in a wire dot head for printing through the projection of wire by a drive contained in a holder. CONSTITUTION:A back holder 21 of high heat radiation material such as aluminium is composed of two split sections such as the first back holder 21'a and the second back holder 21'b, with a vibration-resistant rubber 80 sandwiched in between. This rubber is fixed with an adhesive to make a back holder unit. The back holder unit does not resonate, and the rate of sound generation is low, even if a vibration is transmitted from a heat radiation plate because of varying intrinsic vibration frequency of the back holder. If the number of sections of the back holder unit is changed, the intrinsic vibration frequency varies, accordingly the resonance is prevented by changing the number of sections according to the kind of vibration to be transmitted. The intrinsic vibration frequency can be changed by properly selecting other materials to be inserted between the sections instead of vibration-resistant rubber 80 if the number of sections is the same.
