摘要:
A method for bleaching silver halide color photographic materials is described using a bleach solution containing an organic acid metal complex salt and hydrogen peroxide or a compound releasing hydrogen peroxide, wherein the bleaching activity of the bleach solution can be effectively maintained for a long period of time by supplying thereto a replenisher composed separately of a composition containing hydrogen peroxide or a compound releasing hydrogen peroxide and a composition containing an organic acid metal complex salt, which are separately stored and added as a mixture thereof or separately to the bleach solution when the activity thereof is weakened during processing or during storage of the bleach solution.

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).

In each of an organic solvent, an oil-soluble dye and an oil-soluble resin to be contained in an ink for marking, and a resin adopted in an article to be marked with the ink for marking, it is necessary that absolute values of differences between mutual solubility parameters are not more than constant values, respectively.
摘要:
A track width regulating section having a track width, which is smaller than the resolution obtained by the wavelength of the light used for exposure and development of a resist, is formed between a lower core layer and an upper core layer. Since the width of the upper core layer is larger than the track width, magnetic saturation can be effectively reduced. Inclined faces are formed on the upper surface of the lower core layer so as to be inclined in directions away from the track width regulating section, thereby adequately preventing write fringing.

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.
