Title: Ink jet recording apparatus
Inventor: AOKI TAKAO
IPC: B41J2/18
Filed: 1988-06-17
Abstract: PURPOSE:To enable the stable discharge of ink without causing clogging of a discharge port of a recording head and to suppress a wasteful use of ink by making a discharge-recovery means of the recording head operate selectively in accordance of the respective states of recording heads in a plurality. CONSTITUTION:Based on detection signals of thermistor 10C to 10K provided for recording heads 5C to 5K of separate colors, the temperature T of each recording head is measured. In the case when T is lower than T1, an idle discharge A of 200 droplets in made, for instance, from each discharge port of the heads to a cap which is left separated when the recording heads 5C to 5K return to home positions. In the case when T is T1<=T<=T2, an idle discharge B of 50 droplets is made, for instance, from each discharge port to the cap 9 at the home positions, and when T is higher than T2, no idle discharge is made. The selective drive of the recording heads is enabled by repeating these procedures for each head or by setting data on the idle discharge A, the idle discharge B and on no demand for discharge in RAM in accordance with a detected temperature and conducting discharge recovery in parallel.

Title: Controller for output of electricity generator
Inventor: SAWAMURA ISAO
IPC: H02P9/04
Filed: 1978-12-06
Abstract: PURPOSE: To always run an electricity generator within a prescribed output, by reducing or augmenting a generator output instruction when the output of the electricity generator exceeds an upper limit or falls below a lower limit.  
     CONSTITUTION: When a signal Vx produced by a power detector 5 and proportional to the output of an electricity generator exceeds an upper limit Vu, a comparator 8 produces an output. At that time, a relay R 1  is energized, a normally open contact R 1  is closed, and a decrease instruction Ca is applied to an instruction setting unit 13 to reduce the level of a control instruction S. When the signal Vx falls below an a lower limit VL, another comparator 9 produces an output. At that time, another relay R 2  is energized, a normally open contact R 2  is closed, and an increase instruction Co is applied to the instruction setting unit 13 to raise the level of the control instruction S. The output of the electricity generator is thus kept within a range. This results in preventing the overload run of the generator.
