Title: Thermal head drive control circuit in thermal printer
Inventor: KADOUCHI ATSUSHI
IPC: B41J2/36
Filed: 1987-04-30
Abstract: PURPOSE:To make a printing density per line constant, by a method wherein a heating element drive voltage and/or a heating element conduction time are so controlled that the heating value of a thermal head is decreased with the increase of the temperature of the thermal head in the vicinity of a heating element shown by a terminal-to-terminal voltage. CONSTITUTION:The amount of a voltage decrease DELTAE from the steady state of a terminal-to-terminal voltage Ec of a capacitor 34 represents the amount of a temperature increase of a thermal head 4 in the vicinity of a heating element 41. The voltage Ec is lowered with the increase of the temperature of the thermal head 4 in the vicinity of the heating element 41. The terminal-to- terminal voltage Ec is inputted to a strobe pulse generating circuit 37, and the strobe pulse generating circuit 37 outputs a pulse of a width according to the voltage Ec as a strobe pulse SB in synchronism with a trigger signal TP sent from a printer control circuit 1 to send it to each AND gate 22. Therefore, the temperature increase in the vicinity of the heating element 41 results in the reduction of a heating element conduction time, which prevents the occurrence of irregularities in printing density attributed to the temperature increase around the heating element 41.

Abstract: PROBLEM TO BE SOLVED: To prevent a friction ring from becoming damaged at the time of its use and also prevent the friction ring and a backflow check ring from becoming worn out when used by forming the friction ring sliding in contact with the backflow check ring using a ceramic product of silicon nitride above the specific value of bending strength. SOLUTION: A screw head 1 is screwed into the tip of a screw 6 for an injection molding machine, and a friction ring 2 of cylindrical shape is inset on the screw head 1 and is fixed with a push metal 4. In addition, a backflow check ring 3 is loosely inset in a space between a tapered face 4a formed on the push metal 4 and the friction ring 2. Further, the friction ring 2 is made of a ceramic product of silicon nitride above 80kg/mm<2> of bending strength. The backflow check ring 3 is formed of a metal material higher in strength than the friction ring 2. The ceramic product of silicon nitride has such a characteristic that it is smoothly slidable especially with a ferrous metal. Therefore, the friction resistance at the time of sliding is reduced by combining the ceramic product of silicon nitride with the metal backflow check ring 3 and thus their mutual wear can be lessened.
