Title (EN) THERMAL HEAD
(FR) TÊTE THERMIQUE
(JA) サーマルヘッド
Abstract:
(EN) A thermal head is provided with: an underglaze layer provided on an insulating substrate; an electrode provided on the underglaze layer; a heating element provided on the electrode; a first protection layer coating at least the heating element and containing glass material; and a second protection layer provided on the first protection layer, having a melting point higher than that of the first protection layer, and made of material having a thermal expansion coefficient which is substantially constant with respect to temperature at 1000°C or lower.
(FR) Une tête thermique selon l'invention est pourvue de : une couche de sous-glaçure disposée sur un substrat isolant ; une électrode disposée sur la couche de sous-glaçure ; un élément chauffant disposé sur l'électrode ; une première couche de protection revêtant au moins l'élément chauffant et contenant un matériau en verre ; et une seconde couche de protection disposée sur la première couche de protection, ayant un point de fusion supérieur à celui de la première couche de protection, et constituée d'un matériau ayant un coefficient de dilatation thermique qui est sensiblement constant par rapport à la température inférieure ou égale à 1 000 °C.
(JA) サーマルヘッドは、絶縁基板上に設けられたアンダーグレーズ層と、前記アンダーグレーズ層上に設けられた電極と、前記電極上に設けられた発熱体と、少なくとも前記発熱体を被覆する、ガラス材料を含む第1保護層と、前記第1保護層上に設けられ、前記第1保護層よりも高融点であり、1000℃以下の熱膨張係数が温度に対して概略一定の材料で形成された第2保護層と、を備える。
