The deterioration in the focusing spot by the change in the oscillation wavelength arising from the mode hop and output change of the semiconductor laser 1 is lessened over the entire part of the optical system according to this constitution in spite of using the single lens which is formed by using an acrylic resin and is not corrected in chromatic aberration. The optical system for recording and reproducing of the optical information medium optimum for the case in which the oscillation wavelength of the semiconductor laser changes sharply is obtd. in this way.

Abstract: PURPOSE:To provide excellent oxidation resistance and enable easy discrimination of the oxidation resistance, by providing a recording film comprising at least tellurium (Te) or a Te alloy, carbon (C) and hydrogen (H) on a base, and causing the recording medium to absorb light in a far infrared region of specified wavelengths by chemical bonds between organic carbon (C with H bonded thereto) and Te. CONSTITUTION:A recording film absorbs light in a far infrared region of a wavelengths of 25-100mum by chemical bonds between organic carbon (C with H bonded thereto) and Te, in an information recording medium which comprises a Te-C film comprising at least Te or a Te alloy and C as the recording film on a base. The absorption spectrum of the optical recording film in the wavelength range of 25-100mum is measured. Absorption in the far infrared region occurs only in the recording film having the chemical bonds between the organic carbon C (C with H bonded thereto) in CH3, CH2 or the like and Te, that is, the Te-C film. Therefore, discrimination between the Te-C film and a co- deposited Te-C film can be made speedily and easily, that is, the propriety of oxidation resistance of a film produced by an unknown method and comprising Te, C and H can be discriminated speedily and easily.

Filed: 1988-03-30
Abstract: PURPOSE:To more finely decompose character picture elements of high density into gradations and to give a uniform gradation to paper white picture elements of low density by providing a diode between an operational amplifier and an A/D converter. CONSTITUTION:A diode 44 is provided between an operational amplifier 42 and an A/D converter 43.

Abstract: PURPOSE:To design an electronic device discriminating the grade of a delay in wiring. CONSTITUTION:In steps 11 and 12, a wiring resistance and wiring capacity are extracted from the mask layout of an electronic device. The time constant RC of wiring is calculated from the extracted wiring resistance and capacity in step 13. In step 14, the adaptability of wiring layout is discriminated by discriminating a delay in wiring in the electronic device by performing fuzzy reasoning by using the extracted wiring resistance and capacity as fuzzy input variables and based on the wiring resistance and capacity of previously inputted wiring layout and a membership function regarding a delay in signal. In step 16, the layout design is again tried or the layout is modified, since signal propagation cannot be performed well when the wiring resistance and capacity are too large or the time constant is too large to the signals to be transmitted. In addition, when it is discriminated that the wiring layout is suitable in step 15, the electronic device is manufacture based on the layout.
