    摘要: A sound field measuring device according to the present invention uses a measurement signal which has at least one change point and whose frequency spectrum has a shape corresponding to a shape of a frequency spectrum of a background noise. This enables a sound field measurement, which is for measuring an impulse response or transfer function of a sound field space which is a linear time-invariant system to be measured, to be performed with a high S/N ratio over a wide frequency band.

    摘要: [Problem]To provide a light-emitting device as a point light source having a broad emission spectrum by a safe and simple process.[Means for Solving the Problem]The discharge light source shown in FIG. 1 is composed of an insulated pipe 30 and electrodes 31a and 31b. Projections 32a and 32b extend from the electrodes 31a and 31b. When a voltage is applied to the electrodes 31a and 31b in an argon gas flow through the insulated pipe 30 passing between the projections 32a and 32b, a glow discharge is generated thereby emitting light in the area between the projections 32a and 32b. The interval between the projections 32a and 32b is so narrow that the emitting area is small, and thus the light source serves as a point light source. The emission intensity increases with an increase of the gas flow rate, whereby a continuous broad emission spectrum is produced over the ultraviolet to visible region.

    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 semiconductor laser having a plurality of semiconductor laser chips laminated by solder layers which cause no interference with laser beams is provided. To this end, each of the semiconductor laser chips has a solder sump recess formed in the surface to be soldered at an end adjacent to a laser beam radiating surface and extending through portions of the chip except an active layer. This semiconductor laser is manufactured by a method comprising the steps of forming grooves in a surface of an epitaxial substrate along boundaries of semiconductor laser chip areas for defining laser beam radiating surfaces, each of the grooves extending through portions constituting the substrate except an active layer and having a bottom substantially parallel to the epitaxial substrate surface; cleaving the epitaxial substrate along the grooves to provide the semiconductor laser chips with laser beam radiating surfaces defined by the cleaved surfaces; and laminating the plurality of semiconductor laser chips one above another by soldering.
