Title: Amplifier circuit
Inventor: YAMAMOTO TAKESHI
IPC: H03G11/00
Filed: 1989-11-02
Abstract: PURPOSE:To obtain an amplifier circuit capable of securing the dynamic range effectively by comparing the output voltage of an amplifier section with a reference voltage and supplying a current to the impedance output terminal at a high gain stage of the amplifier section when the output voltage is lower than a clip voltage. CONSTITUTION:When an output voltage Vout is lower than a clip potential VCL, a current is supplied to the output terminal at the high gain stage A of an operational amplifier and the level is increased. Thus, the operational amplifier loses its own control capability and voltage feedback is produced to apply clipping so that the output level is not lower than the clip potential VCL. Since the breakdown voltage of transistors(TRs) does not limit the circuit operation the output voltage Vout of an output stage B is a waveform output limited by the clip voltage VCL. Moreover, since the output of the clip circuit is shaped independently of emitter clip of TRs, the circuit is simplified and not affected with an error of the clip level or a temperature drift. Thus, the dynamic range is effectively ensured.

Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To discourage a moire phenomenon or make it inconspicuous by providing a non-linear lattice-like conductor or a plurality of annular conductors provided adjacently on a transparent sheet. SOLUTION: Related to a front-surface filter, a lattice-like conductor for anti-moire is pasted on a glass or resin film, or it is directly printed, or a metal foil is pasted on the resin film to manufacture a panel with high electromagnetic wave shielding characteristics.

A pattern where vertical lines and horizontal lines are arranged in lattice using curved lines makes moire inconspicuous. Using broken lines, with vertical and horizontal lines provided, makes the moire inconspicuous. Arranging curved lines at random further makes it inconspicuous.
