Title: Digital signal processing circuit
Inventor: EGUCHI TAKEO
IPC: H03K5/13
Filed: 1991-12-27
Abstract: PURPOSE:To facilitate the circuit integration and to easily obtain a required delay by connecting a variable current source onto a common current path of a,reproduction amplifier and controlling the variable current source so as to control the delay time of an output signal. CONSTITUTION:An equivalent load resistor having the same dynamic characteristic as that of an emitter resistor of transistors(TRs) Qa, Qb being components of a reproduction amplifier 2 employing a differential amplifier and whose resistance is larger than the resistance of the emitter resistor is connected to collectors of the TRs Qa, Qb. The equivalent load resistor is realized by diodes Da, Db and Dc, Dd. The equivalent load resistor is inversely proportional to a current flowing to the collector of the TRs Qa, Qb, and then a current flowing to a common path of the emitter side. The delay time in the output signal is controlled by the current. Thus, the delay time is controlled by varying a current source 15. Through the constitution above, since a desired delay is obtained without use of a variable capacitor or the like, the configuration is simplified and suitable for circuit integration.

IPC: B41J2/185
Filed: 1992-12-28
Abstract: PURPOSE:To stably emit ink by sucking a proper amt. of ink by detecting whether an ink supply container inserted under pressure is a new one or a re-inserted one to alter the suction amt. of ink in suction operation corresponding to the detected result. CONSTITUTION:A power supply is closed and a container mounting detection part detects whether an ink supply container 21 (hereinbelow referred to as a container) is mounted. When the mounting of the container is confirmed, an ink exhaustion detecting part detects whether the residual amt. of the ink in the container is a predetermined value or more. When it is confirmed that the residual amt. of the ink is a predetermined value or more, a detachment detecting part 14 detects whether the mounted container is inserted first. In the case of the first (new container) insertion, a suction mode setting the suction amt. of the ink low is taken because the mixing amt. of air bubbles is low to perform suction operation to transfer to a recording mode. Since the mixing amt. of air bubbles becomes much in the case of the container on the way of use, a suction mode setting the suction amt. of the ink much is taken to perform suction operation to transfer to the recording mode.
