Title: Analog switch
Inventor: HAMADA FUMIO
IPC: H03K17/687
Filed: 1986-05-21
Abstract: PURPOSE:To eliminate the distortion of a signal at switch-on by supplying a signal in response to a signal on a signal line to a gate when a transistor (TR) is turned off. CONSTITUTION:A control signal is fed to the gate of a TR 9 via a synthesizing circuit 6, where the control signal from a terminal 13 and a signal being the amplification of a signal appearing at the serial connection point of a channel comprising TRs 7, 8 by an amplifier 5 are synthesized. When a base band switch is turned on, a signal on the signal line in addition to an off bias control signal at the terminal 13 is amplified and fed to the gate. In selecting the gain of the amplifier 5 and the synthesis ratio of the circuit 6 to desired values, the fluctuation of a gate-source voltage of the TR 9 due to the signal on the signal line is minimized.

Title: Developing apparatus using magnetic brush
Inventor: NAKASHIMA YASUTAKA
IPC: G03G15/09
Filed: 1977-09-28
Abstract: PURPOSE: To maintain constant the quantity of a developing agent, which is to be stored in the gap between a photosensitive member and a sleeve, so as to ensure stable development by arranging a restricting member in the vicinity of a magnetic roller thereby to restrict the developing agent from being attracted directly by the magnetic roller.  
     CONSTITUTION: A magnetic member (or restricting member) 22 is arranged above a sleeve 1. The leading end 23 of the magnetic member 22 is bent in a radius concentric to a magnet roller 2 and is arranged in the vicinity of a reservoir 19 of the developing agent. The rear half is arranged to be gradually spaced from the magnet roller 2, and the bent rearmost portion 24 is fixed to a hopper 24. As the quantity of the developing agent in the reservoir 19 is increased, the agent is attracted toward the magnetic member 22 by the magnetic force established between itself and the magnet roller 2 of the member 22 so that it is returned in the opposite direction, as shown in arrow. Since the magnetic force between the roller 2 and the magnetic member 22 is accordingly attenuated, the developing agent is allowed to fall down in the direction of arrow 26 until it is returned to the hopper 5

Title: Ink jet recorder
Inventor: TANAKA RYOICHI
IPC: B41J2/485
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To realize high quality printing of photographic quality level by varying the duration of a second signal for keeping the expanded state of a pressure generation chamber thereby regulating the quantity of a very small ink droplet being jetted through a nozzle opening. SOLUTION: In order to jet a very small ink droplet, a first signal 401 for exciting the meniscus in a nozzle opening abruptly is driven shorter than a period Tc to oscillate the Helmholtz oscillation system of period Tc thus exciting the meniscus abruptly. Thus excited meniscus oscillation of period Tc is temporarily pulled into the nozzle opening and then reset toward the nozzle opening face before a part of meniscus standing up above the nozzle opening face is separated and jetted as a small ink droplet. Since the influence of meniscus push-up force generated by a third signal 403 for contracting the pressure generating chamber is varied when the duration of a second signal 402 402 is varied, the extent and speed of meniscus standing up above the nozzle opening face are varied thus varying the quantity of a small ink droplet being jetted.

Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide the tensioning apparatus for applying fine and uniform tension to the total width of a transfer article and responding to tension fluctuations during operation in a moment. SOLUTION: A spring plate 14 coming into contact with one surface 1a of a transfer article 1 to impart tension to the transfer article 1 is divided into a plurality of divided spring plates 14A in the direction crossing the direction of a moving route 2 and the group of these spring plates 14A is brought into contact with one surface 1a. The group of the divided spring plates 14A comes into contact with one surface 1a of the transfer article 1 moving on the moving route 2 elastically (under pressure) and tension is imparted to the total width of the transfer article 1 by the elastic repulsive force of the group of the divided spring plates 14A.  Even if tension fluctuations are generated in the lateral direction of the transfer article 1, the divided spring plate 14A corresponding to a fluctuation place imparts tension while independently (individually) performs elastic adjustment by elastic repulsive force. The respective divided spring plates 14A respond to tension fluctuations during operation in a moment to correspond thereto.
