Title: Waveform shaping device
Inventor: IGAWA KEIICHI
IPC: H03K5/02
Filed: 1991-11-21
Abstract: PURPOSE:To reduce the transient response time by closing a capacitor charging switch only in the transient response state so as to reduce the time constant RC in the transient response. CONSTITUTION:A DC component is eliminated from an input terminal from an input terminal 1 by an AC coupler 2 and the result is inputted to an inverting logic element 3. When a control signal from an input terminal 5 is in the normal state and a transient signal from an input terminal 8 is in the steady-state, a capacitance charging switch 9 and a ground switch 6 are opened to set an on/off control resistor 7. An input small signal in this state is subject to level conversion into a logic level and waveform-shaped and outputted. Furthermore, when a control signal from the terminal 5 is in the normal state and a signal from the terminal 8 is in the transient state, the switch 6 is opened and the resistor is set. Moreover, the switch 9 is also closed to reduce the capacitance thereby reducing the time constant RC, resulting in that the transient response time is reduced.

Abstract: PROBLEM TO BE SOLVED: To maintain the high speed operation performance of an internal logic circuit and limit a leakage current to a small value both at the time of waiting and at the time of operation, while the increase of an area is suppressed. SOLUTION: One transistor 6 is used in common by a plurality of NAND circuits NA1-NA4. The common transistor 6 is connected between a pseudo- ground line VSNL connected to the grounding nodes of inverters 4 in the respective NAND circuits and a ground. The threshold voltage is predetermined to be higher than the threshold voltages of transistors of which the inverters 4 are composed. The common transistor 6 is controlled by block selection signals P1. As the gate width of the common transistor 6 can be large, the high speed operations of the respective inverters 4 can be maintained. At the time of waiting, a leakage current is limited by the off-operation of the common transistor. At the time of operation, the leakage current is limited by the off-operation of the common transistor in a nonselective circuit block.

Abstract: PURPOSE:To reduce the deviation the coloring of a read original by turning an image forming optical means so as to vary an incident angle of a reflected light from the original against a change in a spectrum transmittivity of the image forming optical means due to a temperature change in the reader.
