Title: Ink jet recorder
Inventor: MIURA MASAYOSHI
IPC: B41J2/175
Filed: 1980-08-11
Abstract: PURPOSE:To facilitate the control of discharging of ink droplets and stopping thereof by a method wherein an ink discharging port is placed in a space where a change  of pressure gradient is present due to an abrupt deflection of an airflow so that the pressure gradient generated at a liquid meniscus is changed. CONSTITUTION:By using a pressure regulating valve 60 or 61, a pressure balance is provided such that the meniscus formed at point O is neither retracted nor split into droplets when no electrical signal 21 is applied. When an electrical signal 21 is applied, the pressure gradient at the point O is increased to exceed the holding force DELTAPl provided by the surface tension of the ink, so that the meniscus is broken into the ink droplets, which are discharged through an air discharging port 13. In the ink jet recorder of such construction, the printing speed is determined by the mechanical vibrating capability, the flight of ink droplets is stable and the flying speed  is high. In addition, the amount of the ink droplets discharged can be controlled by  the magnitude of changes in the spacing between the ink discharging port 16 and the air discharging port 13.

Abstract: PURPOSE:To improve an operational safety an eliminate the chance of user being burnt, by arranging such that an electromagnetic device is positively actuated and an automatic toasting switch is returned back to its original state immediately after a power plug is placed into a wall socket. CONSTITUTION:Upon a micro-computer 5 being energized, an output port 11 is made as ''H'' for keeping a thyrister 9 electrically conducted for a brief period. Then, the output port 11 is made as ''L'' for waiting until a switch signal is inputted to an input port 10. Upon an automatic toasting switch 6 being closed and the switch signal being inputted, an judgement is made as to how many times a bread is toasted and the energizing time period of heater 7 is computed. With the lapse of computed time after the switch is turned ON, the output port 11 is made as ''H'' again for electrically energizing the thyrister 9. The automatic toasting switch 6 is thus opened. Should the power is supplied with the automatic toasting switch 6 closed, the automatic toasting can be instantly opened for preventing a heater 7 from being energized. An operational safety is thus ensured.
