Title: Input and output circuit
Inventor: SHIOMI MAKOTO
IPC: H04N5/93
Filed: 1982-08-27
Abstract: PURPOSE:To use minimum input/output pins and to suppress signal deterioration due to a noise, by driving an attenuation type element such as a 1H (horizontal period) glass delay line and a surface acoustic wave filter in a balanced state and obtaining the output of the element in an unbalanced state. CONSTITUTION:The 1H glass delay line is driven by a differential input. Namely, signals differing in signal are outputted to the emitter follower consisting of a transistor 30 and a resistance 32. Then, a difference signal is impressed between inputs 1-6 and 1-7 of the glass delay line (equivalent circuit) 1, which is driven by the differential signal. Consequently, a signal current flows as shown by an arrow 6'. At this time, no signal current passes through the power source terminal 6-1 of an amplifier 6, so the terminal 6-1 is stable. Therefore, no noise due to variation in source voltage is generated. Consequently, minimum input/ output pins are used to suppress signal deterioration due to a noise.

Title: Method and apparatus for recovering ink jet recording head
Inventor: O RITSUSAN
IPC: B41J2/165
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent ink in nozzle from stiffening and hardening through natural evaporation by separating an ink jet recording head adhering to a cap member therefrom at the time of pressurizing operation during ink suction operation through a suction means and eventually isolating the nozzle from the outer air by capping. SOLUTION: Clogging of an ink jet recording head 1 is removed by applying a pressure by a pressure pump for a specified time and rotation of the pressure pump 15 stopped to end pressurization. The ink jet recording head 1 is then shifted to a wipe position separated from a cap member 3 and a suction pump is operated. Since an enclosed negative pressure space is not formed between time cap member 3 and the ink jet recording head 1 adhering thereto, ink is not missed and a meniscus appropriate for ink ejection is formed by the surface tension of liquid and the difference of head between the ink jet recording head 1 and the liquid level in an ink tank.
