    摘要: A semiconductor integrated circuit for controlling the substrate potential is disclosed, in which a substrate potential generating circuit is connected to a substrate and can be operated on at least a certain operation voltage level to generate the substrate potential. A detection circuit outputs a first detection signal upon detecting that the substrate potential has become lower than the operation voltage level by more than a preset amount, and outputs a second signal upon detecting that the substrate potential has reached a preset level which is slightly lower than the operation voltage level. A charging circuit charges the substrate upon receiving the first detection signal and interrupts the operation of charging the substrate upon receiving the second detection signal.

    摘要: Provided is a light adjusting noise reduction circuit in which the vibration noise accompanying turning ON/OFF of a piezoelectric transformer. A full bridge circuit is controlled by a full bridge drive circuit so as to switch an input voltage (VB1) from an input voltage source and outputs it to a low pass filter. The output from the low pass filter is supplied to a piezoelectric transformer. The output current (IO) from the piezoelectric transformer is supplied to a discharge tube. Each of FET of the full bridge circuit has a drive frequency decided by a voltage control type oscillator. The full bridge circuit is connected to a duty variable circuit and a peak value control circuit. The peak value control circuit forms a rise and a fall of a waveform to be (1−cosωt).

    摘要: An electromagnetic wave amplifier and an electromagnetic wave generator operate using electron beams in a vacuum environment. The amplifier, arranged in a vacuum environment, comprises an electron emitting section for emitting electron beams and an amplifying section for amplifying an inputted electromagnetic wave in one direction by utilizing energy received from an electron beam emitted from the electron emitting section and traveling in the vacuum along a dielectric waveguide having a wave-shaped form. The generator, also arranged in a vacuum environment, comprises an electron emitting section for emitting electron beams and an oscillating section for generating an electromagnetic wave by utilizing electron beams emitted from the electron emitting section and travelling in the vacuum along a dielectric waveguide having a composite wave-shaped form.
