    摘要: A light-receiving device of a pin junction structure, constituted by a quantum-wave interference layers Q1 to Q4 with plural periods of a pair of a first layer W and a second layer B and carrier accumulation layers C1 to C3. The second layer B has wider band gap than the first layer W. Each thicknesses of the first layer W and the second layer B is determined by multiplying by an odd number one fourth of wavelength of quantum-wave of carriers in each of the first layer W and the second layer B existing at the level near the lowest energy level of the second layer B. A &dgr; layer, for sharply varying energy band, is formed at an every interface between the first layer W and the second layer B and has a thickness substantially thinner than the first layer W and the second layer B. As a result, when electrons are excited in the carrier accumulation layers C1 to C3, electrons are propagated through the quantum-wave interference layer from the n-layer to the p-layer as a wave, and electric current flows rapidly.

    摘要: A light-emitting device comprising an emission layer which has a single layer structure is formed. The emission layer is sandwiched by a first quantum-wave interference layer constituted by plural periods of a pair of a first layer and a second layer, the second layer having a wider band gap than the first layer, and a second quantum-wave interference layer constituted by plural periods of a pair of a third layer and a fourth layer, the fourth layer having a wider band gap than the third layer. The first quantum-wave interference layer functions as an electron reflection layer, and its thickness is determined by multiplying by an odd number one fourth of quantum-wave wavelength of the injected electrons. The second quantum-wave interference layer functions as an electron transmission layer, and its thickness is determined by multiplying by an odd number one fourth of quantum-wave wavelength of the injected electrons. As a result, luminous efficiency of the device is improved. A barrier layer is formed at each interfaces between the first quantum-wave interference layer, the emission layer, and the second quantum-wave interference layer. As a result, generation of electron-hole pairs is improved.

    摘要: A color image reproduction apparatus includes a light source, a filter, a sensor means, an ink ribbon, a printer including a printer head and a printer drive, a feeder and a controller. The light source illuminates spots on the color original and light reflected therefrom is filtered by one of three aligned segments of the filter which are connected end-to-end in an alignment direction which three segments respectively filter different first, second and third portions of the visual spectrum. The sensor is disposed behind the filter and senses the light filtered by one of the three different filter segments when the one of the segments is disposed in front of sensor. The sensor outputs an intensity signal indicating the intensity of the sensed light. The ink ribbon is fixed in relation to the filter and has three different color ink layers which are attached to each other end-to-end in the same alignment direction as are the light filter segments. Each ink layer is spaced a predetermined distance from a corresponding one of the three different filter segments. The printer head is disposed behind the ink ribbon and is spaced from the sensor a distance equal to the distance between corresponding ink layers and filter segments so as to be operable to apply ink from the ink layers to a print surface. The feeder successively feeds the three different filter segments across the front side of the sensor, and simultaneously successively feeds the three different ink layers across the front side of the printer head.

    摘要: A diffracted sound reduction device includes: a reproduction speaker that outputs reproduced sound having properties indicated by an input signal; control speakers each of which reproduces corresponding one of control signals, the diffracted sound being a part of the reproduced sound and arriving at corresponding one of the control points except the control point at the listener's position; and control filters each of which filters the input signal to generate corresponding one of the control signals. Each of the control points faces a corresponding speaker from among the reproduction speaker and the control speakers. Each of the control filters generates the corresponding one of the control signals so that a sound pressure of the diffracted sound at corresponding one of the control points is lower than a sound pressure of direct sound that is a part of the reproduced sound which arrives at the control point of the listener's position.
