Includes an electrical discharge state distinguishing circuit (6) for distinguishing at least two inter-electrode states, including electrical shorting and normal electrical discharge, between a wire electrode (E) and a workpiece (W), and an inter-electrode current waveform control means for supplying, and for switching between supply of, a triangular wave and a trapezoidal wave current to the electrodes. According to the inter-electrode state distinguished by the electrical discharge state distinguishing circuit (6), in cases where the inter-electrode state is that of electrical shorting (Y1), the inter-electrode current waveform control means supplies a triangular wave current (I) to the electrodes, and in cases where the inter-electrode state is that of normal electrical discharge (Y3), it supplies a trapezoidal wave current (I) to the electrodes. Breakage of the wire electrode (E) can be avoided and machining speed can be improved.

摘要： A first cutter 130 (cutting unit) is provided between a color recording unit 120 (the first printing unit) and an overcoat recording unit 140 (the second printing unit). A portion whereon color printing is completed by the color recording unit 120 of a recording paper 200 (printing medium) is cut off by the first cutter 130 and detached. An overcoat recording unit 140 performs an overcoat process on the detached recording paper (printing medium strip). In parallel with this, the color recording unit 120 performs next color printing on the recording paper 200. This makes it possible to reduce a printing time in a printing device including a plurality of printing processes without deteriorating printing quality. Further, an useless paper feeding is eliminated by optimally arranging the color recording unit 120, the first cutter 130, the overcoat recording unit 140, and the second cutter 160, etc. in accordance with a size of a printing area.

摘要： An information recording medium comprising a substrate having a recording surface provided with emboss pits or guiding grooves, a reflective film formed on the recording surface of the substrate, and a first protective film formed on the reflective film. This information recording medium is featured in that both sides of the information recording medium are constituted by a first surface provided with the protective film and by a second surface formed opposite to the first surface, and that an irradiated light beam is irradiated through the first surface, a recorded information being reproduced based on changes in light intensity of the reflected light beam. The distance between the recording surface of the substrate and the light incident surface is smaller than a thickness of the substrate, and a surface roughness “R” of the light incident surface meets a relationship represented by the following formula (1): R≦λ/(8n)   (1) wherein λ is a wavelength of the light beam, and n is a refractive index of the first protective film to a light having the wavelength λ.

摘要： Target fluid is made into electrolyte solution when measured fluid-quality value is lower than a first condition value, by substituting an impurity anion contained in the target fluid with a predetermined anion and substituting an impurity cation contained in the target fluid with a predetermined cation, and purified when the fluid-quality value is higher than a second condition value. The above procedures are repeated, so that the fluid-quality value of the target fluid falls within a predetermined range, to make the target fluid into electrolyte solution with a correlation between pH and conductivity.

摘要： An apparatus generates first shared information that is shared by the apparatus and a recording medium by performing a first bilateral authentication. The apparatus encrypts overwrite data that is used to erase key information item recorded in the recording medium using the first shared information. Encrypted overwrite data is transferred to the recording medium. Second shared information is generated and shared by the apparatus and the recording medium by performing a second bilateral authentication between them. The apparatus receives data that is encrypted using the second shared information and that has been used by the recording medium for erasing key information. Encrypted data is decrypted using second shared information item and key information recorded in the recording medium is erased when the decrypted data is identical to overwrite data.
