Filed: 1994-02-04
Abstract: PURPOSE: To improve a noise characteristic and to reduce power consumption by connecting magnification units functioning as balance modulators to multistage sequential logarithm amplifiers as multistage synchronous demodulation circuits. CONSTITUTION: A synchronous logarithm amplifier 40 is connected to a magnification unit stages 26 operating as mutual conductances G or the balance modulators in accordance with the logarithm amplifiers 14 which are connected in series. The outputs of the logarithm amplifiers 14 and the outputs of the magnification units 26 are added at respective stages. A current bus 24 is voltage-converted by a resistance 15 and is outputted to a terminal 20 through a low pass filter 18. The respective magnification unit stages 26 operate as the mutual conductances when prescribed bias is applied to a terminal 28. When clock voltage is applied, they operate as the balance modulators. Thus, they operate as self-clock logarithm amplifiers by supplying the same signals to the terminals 12 and 28 and high sensitivity is obtained for a wide band. Noise is averaged and is set to be zero.

Title: Liquid feed apparatus
Inventor: AOYAMA YOSHIJI
IPC: G01N30/32
Filed: 1995-02-22
Abstract: PURPOSE: To simply carry out supplement and replacement of a solution by providing a flow path which branches the solution sucked from a tank by a pump to a constant flow rate pump, sends to a higher position than the constant flow rate pump and returns to the tank, and a flow path running from the highest position and having a lower end opened to the air. CONSTITUTION: At a flow path 22, a suction pump 21 sucks a solution stored in a tank 20, supplies to a constant flow rate pump 23, transfers to a higher position than the pump 23 and then returns to the tank 20. At a flow path 24, one end of the path is connected to the highest position of the flow path 22, i.e., a point B and the other end is opened to the air through a point D. The solution sucked by the pump 21 partly flows to the pump 23 at a point A and the remaining solution flows through a coil 22A → point B →point C to the tank 20. The points B and D are at the atmospheric pressure, and the point A has a positive pressure because of the solution stored in the coil 22A. Therefore, no air bubbles are generated between the pump 21 and point A, and the pump 23 can operate without being influenced by the air bubbles.  The solution can thus be easily supplemented and replaced.

Abstract: PURPOSE:To prevent the tip of the one side end of a recording chart from floating up extremely, and also prevent the recording chart from being folded and shrinked restraining the printed image from being disturbed by arranging a recording chart guide means which is movable up and down, on the upper side of another side of a separation means located in the transfer path of a fixing device. CONSTITUTION:In order to prevent a recording chart from floating, an edge guide means 31 is arranged on the upper side of an entrance in the place B opposite to the side A where a separation/transfer means for the recording chart is located. This guide means 31 is located above a nip section N, when looked from the place, to which direction the recording chart is transferred, its oblique surface 31a is formed in such a way that the surface becomes lower in relation to be fixing roller 21 as the surface comes closer to the end of the fixing roller. When the recording chart is carried in where its side end A is regulated by the separation/transfer means, the other side end B tends to float up, but is forcively pressed down by the oblique surface 31a of the guide means 31 preventing the chart from being folded or shrinked while it is transferred. And the guide means furthermore prevents the upper surface of the recording chart, on which a toner printed image is transferred, from coming in contact with an insulating cover 23 arranged to the entrance of the fixing device 20 restraining the printed image from being disturbed.
