Title: Detecting device for residual quantity of ink in ink jet recording apparatus
Inventor: IKEDA IKUMASA
IPC: B41J2/175
Filed: 1988-06-17
Abstract: PURPOSE:To enable detection of the exhaustion of ink at a time point when a very small residual quantity of ink is reached, by bending downward the force end part of at least one of electrode needles and by setting the fore end faces thereof at higher positions in stages than the position of an opening end of an ink supply tube. CONSTITUTION:An electrode needle 23 is bent in the shape of L in the part exposed in an ink tank 2, while the lower end thereof is set at a position somewhat higher than the lower end of an electrode needle 22. When an ink level lowers below a level A and further below a level B, a closed circuit between the electrode needle 23 and the ink supply tube 22 is broken and a circuit resistance being as low as several kilo-ohms theretofore changes to be as high as several mega-ohms. This change in the resistance is detected also by a resistance change detecting circuit and an ink exhaustion signal is generated therefrom. Based on this signal, a control element of an ink jet recording apparatus stops a recording operation and an operation of an ink supply pump while executing display of an alarm of the exhaustion of the ink etc.

IPC: H04Q9/00
Filed: 1991-05-24
Abstract: PURPOSE:To obtain a general-purpose telecontrol controller which can selectively control plural telecontrol equipments with no use of a home controller. CONSTITUTION:A terminal L of a telecontrol control part is connected to a plug socket for telephone circuit, and another equipment is connected to a terminal T. When this equipment is first connected to a circuit with an external cell, the voltage change is detected by a voltage detecting circuit 54. This detection output is inputted to a control circuit 50. Thus a 1st relay 52 is turned on and at the same time a main equipment is connected to the circuit. Then an identification number is inputted from an external telephone set and a 2nd relay 53 is turned off. As a result, another equipment is separated from the circuit and only the main equipment can be telecontrolled.

Title: Current feedback type transistor driving circuit
Inventor: INABA KATSUHIKO
IPC: H03K17/60
Filed: 1984-07-19
Abstract: PURPOSE:To reduce power consumption of a DC power source by providing a series circuit consisting of the first and second winding of a pulse transformer, a diode and a switching element in the second winding of a current transformer. CONSTITUTION:When a transistor TR20 becomes on by pulse driving, current flows from a DC power source VCC to winding N9 of a pulse transistor 21, and driven TR23 becomes on, and current flows in the winding N6 of a current transformer 12. Current of winding N7 thus generated is fed back to the winding N9 through a diode 15. When TR20 becomes off, and at the same time TR19 is pulse driven and becomes on, feedback current from winding 7 flows in winding N8 through a diode 16, and TR23 is off driven. Thus, current to be flowed in a resistance 18 can be made small as current sufficient to make positive feedback operation is enough for the purpose.
