Abstract: PROBLEM TO BE SOLVED: To minimize drive differential voltage to a non-driving piezoelectric element and thereby stabilize and ensure the amount of ink jetted by supplying a prescribed potential to respective time division lines and selection lines, providing time division drivers which select potential and drive, and applying drive differential voltage of a specified value to both ends of the piezoelectric elements. SOLUTION: Time division lines 111 to 114 which apply voltage at a prescribed time to some piezoelectric elements 411 to 44 M of the side wall of a pressure chamber filled with ink, selection lines 121 to 12M are provided, the piezoelectric elements 411 to 44 M are arranged at the intersection across both lines. Potentials E5 , E1 , E2 , E6 , E4 for waiting, driving, and non-driving, respectively, are applied to the time division lines 111 to 114 and the selection lines 121 to 12M, respectively, the respective potentials are selected by drivers arranged in them and applied to the piezoelectric elements 411 to 44 M. Potential is applied to the division lines 111 to 114 and the selection lines 121 to 12M so that voltage applied to both ends thereof may be the drive differential voltage for driving, 1/3 or -1/3 of the drive differential voltage for non driving. Therefore, ink leakage from the non-driving piezoelectric elements are prevented and makes the system less expensive and highly reliable.

Filed: 1990-08-08
Abstract: PURPOSE:To prevent generation of flames in advance by providing a photoelectric sensor in a smoke discharge hood to detect shut-off quantity and inputting a signal into a control means to shut off a fuel shut-off valve. CONSTITUTION:A photoelectric sensor 15 of transmission type is provided in smoke discharge hood 3 so that signals of said sensor 15 are inputted into a control means 16 to actuate a shut-off valve 6 and an alarm device 17. The sensor 15 consists of a floodlight projector 18 and a light receiver 19 and the projector 18 and the receiver 19 are disposed on the opposite sides of the hood 3 to allow the smoke sucked by an exhaust fan 13 to flow between them. When a large amount of smoke is generated from cooking of tempura and sucked into the hood 3, the light from the projector 18 of the sensor 15 is intercepted and hence the light flowing into the receiver 19 is largely reduced. The sensor 15 detects a decrease in quantities of received light to find out in advance occurrence of a fire of tempura and when the output of the sensor exceeds certain limit, a control means 16 actuates the shut-off valve 6 to cut off supply of fuel and also actuates the alarm device 17. Consequently a fire of tempura can be avoided and safety is improved, without being affected by a cooking apparatus in use.
