Title: Trimming of membrane thermal printing head
Inventor: USUDA AKIHIRO
IPC: H01C17/26
Filed: 1994-10-31
Abstract: PURPOSE: To dispense with the time required in trimming processing and to adjust the minute resistance value in the vicinity of an objective resistance value by adjusting pulse width in such a state that electric energy is fixed until a resistance value reaches an objective resistance value after resistance difference reaches a constant value. CONSTITUTION: Heating elements 12 are formed on a substrate 11 composed of an insulating substrate in one row by membrane technique. At the time of trimming processing, rough adjusting processing increasing the electric energy of a trimming pulse is performed in order to shorten a trimming processing time until the difference between the resistance value of the heating elements 12 and an objective resistance value becomes a constant value. After the resistance value reaches the constant value, pulse like power is applied to the arbitrary heating element 12 while pulse width is adjusted in such a state that electric energy is fixed until the resistance value of the arbitrary heating element 12 reaches the objective resistance value.  By this constitution, the resistance value of the heating elements 12 can be accurately set to the objective resistance value and the irregularity of image density generated by the irregularity of a resistance value is prevented to obtain a good image.

Abstract: PURPOSE: To precisely measure the thickness of coating layers, which have been coated on both faces of a base material, irrespective of the rocking of a coating sheet. CONSTITUTION: The surface of a coating layer on the upper side is measured by a first displacement meter 9. The surface of a coating layer on the lower side is measured by a second displacement meter 11 which is arranged so as to face the first displacement meter 9. The surface of a base material Sc is measured simultaneously by a third displacement meter 13 in a position which has been displaced by a prescribed amount to the sheet width direction with reference to the first displacement meter 9. A measured value Da by the first displacement meter 9 is subtracted from a measured value Dc by the third displacement meter 13. The thickness Ta of a coating layer Sa on the surface of the base material Sc is computed.  The total thickness T of a coating sheet S is computed on the basis of the measured value Da by the first displacement meter 9 and on the basis of a measured value Db by the second displacement meter 11. The thickness Tc of the base material Sc and the thickness Ta of the coating layer Sa on the surface are subtracted from the total thickness T. The thickness of a coating layer Sb on the rear surface is thereby computed.

After the calling is started, the circuit 3 monitors the calling time and updates the calling enable time every prescribed time and when the charge is deposited additionally and the calling time is added. Thus, the residual quantity of the calling time is discriminated to use the calling charge efficiently.
