Title: Serial thermal printer
Inventor: ISHIKAWA HITOSHI
IPC: B41J29/46
Filed: 1986-03-26
Abstract: PURPOSE:To allow a user to know that the number of times of the return of a carriage to a home position become the same with the scheduled number of printing lines preset to a register by an alarm mechanism because the carriage necessarily returns to the home position if the printing of one line is finished. CONSTITUTION:When a carriage is present at the home position and a printing order is applied, a motor 20 is rotated by a shaft 16 and the carriage 23 forwardly moves. When the projection 26c of the carriage 23 is separated from a stopper 54, a thermal head 29 is energized toward a platen to print the predetermined number of characters on a thermal paper. Whereupon, the motor is reversed and the carriage begins to backwardly move and the projection 26c slides to be engaged with the cam body surface 51b of a lever 48 to revolve the lever 48 and the head 29 revolves to be separated from the thermal paper. At the same time, the teeth 38b of a ratchet wheel revolves by one pitch to perform paper feed and projections 24f, 26c stand-by at that position until the next printing order arrives. If the number of printing lines reaches the scheduled number, an alarm mechanism informs this state.

Title: Formation of pattern film
Inventor: KAWASAKI EIJI
IPC: B05D1/32
Filed: 1989-03-23
Abstract: PURPOSE:To obtain a three-dimensional pattern film excellent in corrosion resistance by bonding a film having through-holes in a predetermined pattern to a surface to be coated as a mask and spraying fine particles to said surface from above to selectively etch the same and subsequently applying transparent paint thereto. CONSTITUTION:For example, a photosensitive resin is irradiated with ultraviolet energy through a negative film having a predetermined pattern drawn thereon to selectively cure only the part irradiated with said energy to prepare a film having fine through-holes in a predetermined pattern. This film is bonded to the surface of the film on a steel panel 1 for a car, for example, coated even with a top coat film 4 as a mask. Subsequently, fine particles (e.g. corundum) are sprayed to said steel panel from the upper surface of the mask to selectively etch only the surface parts against which the fine particles strike. Thereafter, transparent paint is applied to the etched parts or the whole surface to form a clear painting film 5. By this method, a three-dimensional pattern film having high corrosion resistance is obtained.
