摘要： PURPOSE:To make the resistance value of resistors collectively uniform without measuring the resistance value of the resistors individually by a method wherein the resistors are exposed to gaseous chlorine trifluoride within a temperature range in which the resistors are not reacted with the chlorine trifluoride. CONSTITUTION:When a DC voltage is applied to voltage application terminals, resistors 13 generate heat, their surface temperature is raised and their reaction with chlorine trifluoride is started. The initial resistance value of the resistors 13 is low. Even when the voltage is applied initially and their surface temperature is increased, the surface of the resistors 13 is gasified as their reaction with the chlorine trifluoride progresses. As a result, their resistance value is increased gradually. When their surface temperature is lowered and set to 80 deg.C finally, their reaction hardly progresses. Consequently, when the voltage is applied to all the resistors 13 in such a way that the surface temperature becomes 80 deg.C at a target resistance value to be adjusted, the resistance values of all the resistors lower than the target resistance value can be equalized to the target resistance value. Thereby, it is possible to obtain the uniform resistance value collectively.

摘要： PURPOSE:To obtain the above thin film type thermal head which can be stably formed by superposing successively a heat storing layer, intermediate layer, heating resistor layer, power feed layer, and anti-abrasion protection layer on a heat resistant base board, thereby improving thermal efficiency for setting. CONSTITUTION:There is provided on a heat resistant base board 11 an insulating material 12 composed of heat resistant resin particles of polyimide 13 and silicon oxide containing an extremely small amount of hydrogen obtained from alkoxy silane to form a heat storing layer 14. An intermediate layer 15 composed of silicon carbide, having a thickness of 0.7-2mum, and a heating resistor layer 16 are formed in succession on said layer 14, on a part of which a power feed layer 17 and anti-abrasion protection layer 18 are successively formed to form a thin film type thermal head. Since in this thermal head the thermal conductivity of the heat storing layer can have a value of 10 -10 cal/cm.deg which is an intermediate value of those of glass and resin, heat efficiency for setting can be improved. And the intermediate layer has a mechanical strength equivalent to that of glass, thereby enabling its application to hard recording material such as card.
