Abstract: PROBLEM TO BE SOLVED: To obtain a display device with simplified production processes which can reduce the production cost and which can always display high-quality images without distortion. SOLUTION: A plurality of monolithic light emitting devices 3 consisting of a plurality of blue LEDs 5Ab, green LEDs 5Ag, red LEDs 5Ar separated by a separation part 11 and mounted on a package board 1 are arranged on the first electrode line pattern 2 formed on the package board 1. A voltage is applied between the second electrode 10 of the LED 5A and the first electrode to select the LED 5A in the matrix arrangement to emit light. A color image can be displayed with a narrow halfwidth of the emission spectrum, good characteristics of each color and color matching, and good visual property. The length t of the separation part 11 is controlled to be twice or more of the length s of the part on the both ends of the strip substrate 7 where emission of light does not occur. Even when the monolithic light emitting devices 3 are connected in the longitudinal direction on the package board 1, the distance between the center light emission points of LEDs 5A is made equal in the connecting part and in other part so that a high-quality image without distortion can be obtained.

Abstract: PROBLEM TO BE SOLVED: To obtain a recording and reproducing apparatus which is excellent in a high-speed and high-density recording operation by a method wherein a specific voltage is applied from a head so as to record or erase information and recorded information is reproduced by detecting the change amount of a capacitance. SOLUTION: A recording medium 10 is arranged on a moving and mounting base 30. While a needle-shaped electrode 21 at a recording head HR is being scanned relatively on an SiO2 film on the surface of the recording medium 10, a pulse voltage, based on recording information, at 20V or lower is applied while a conductive cantilever 22 is made negative, and a strong electric field is applied to the recording medium 10. At this time, carriers (electrons) are injected into respective carrier traps in a heterointerface from the needle-shaped electrode 21 according to the recording information, and information is recorded. When recorded information is read out from the recording medium 10, electrons are injected locally from the needle-shaped electrode 21 at the cantilever 22 into a trap in an SiO2 /SiN interface and into a trap in an SiN silm. A difference in the amount of an electric charge generated locally is detected by the distribution of a capacitance.

Abstract: PURPOSE:To carry out measurement with high time resolution even in the case a stimulus generating apparatus has jitter by standardizing the time distribution of output signal intensity of a probe based on the time distribution of external stimuli to the measuring standard signals. CONSTITUTION:A standard signal S1 from a pulse laser apparatus 1 is sent to a second time-amplitude converter (TAC) 8 as a signal which shows a measurement start after the signal passes a level shifter 2, a level adapter 3, and discriminators 4, 5. When measurement is started, emitted x-rays, which are a response from an object 2 to be measured to the x-rays (probe) radiated to the object 2, are emitted and sent to a detecting means 9. The time correlation between the input pulse signal S2 and the measuring standard signal S1 is measured by the first TAC 15 The time distribution of the intensity of the emitted x-rays from the object 2 measured by the TAC 8 is standardized based on the time distribution according to the time correlation measured by the TAC 15. Consequently, jitter the laser apparatus 1 has is compensated and measurement with high time resolution can be carried out.

Abstract: PURPOSE:To obtain the semiconductor crystal thin film of good crystallizability by scanning an insulator and a semiconductor thin film at the same time with the energy beams which are absorbed mainly by each of the insulator and semiconductor so as to make the boundary between solid phase and liquid phase in the semiconductor thin film projecting along the scanning direction of both energy beams. CONSTITUTION:When a irradiation region with a carbonic acid gas laser beam 13 is preset to be slightly larger than that with argon laser beam 3 by controlling a lens by a proper optical means, a rear-end 4b the carbonic acid gas laser beam irradiation region is behind a backward 3b of the argon laser beam irradiation with respect to the scanning direction 4 of the laser beam. A silicon film 2 reaches the necessary temperature in a shorter time than when irradiating the argon laser beam 3 alone and the temperature of the end parts of the silicon film 2 becomes higher than the center part. A boundary 15 between a liquid phase region 2l and a solid phase region 2s of the silicon film 2 moves with the center part preceding the end parts with respect to the laser beam scanning direction 4. Accordingly, in the recrystallization of the silicon film 2, crystals grow from the center part toward the end parts of the silicon film 2 as denoted by an arrow 16.
