    摘要: The interval Λ between each stripe of interference fringe generated in a conventional n-type contact layer is determined by a function (f(λ)=λ(n2−neq2)−1/2/2) wherein λ, n, and neq represent luminous wavelength λ of lights radiated from a light emitting part 104, refractive index n of the n-type contact layer, and equivalent refractive index neq of the n-type contact layer in guided wave mode, respectively. The remaining thickness δ of the n-type contact layer 102 at the concave part D which is formed at the back surface of the crystal growth substrate may be about Λ/2. When at least one portion of the n-type contact layer which is formed right beneath the laser cavity remains with about δ in thickness, the n-type contact layer arranged even right beneath the laser cavity can maintain excellent contact to a negative electrode. As a result, effective light confinement enables to adequately suppress ripples in FFP owing to lights leaked into the n-type contact layer, to thereby provide a semiconductor laser which oscillates stable lights.

    摘要: An ultra-flat non-consumable electrode welding torch which allows performing a welding operation through a narrow gap between adjacent piping such as welding piping of a boiler panel, to be mounted on a compact automatic welding head, and a welding head provided with such a welding torch are to be provided. As a gas supply mechanism that supplies a shield gas to a welding section formed at the tip of the non-consumable electrode through inside of the torch body for the non-consumable electrode welding, a gas supply path is provided for supplying the shield gas from an outer gas space in a double ring shaped gas space provided around a non-consumable electrode and divided by a partition wall, to an inner gas space through a plurality of orifices provided at regular intervals in the partition wall, and the gas is blown from the inner gas space to the region around the non-consumable electrode through a metal mesh plate. A gas outlet opening provided in the inner gas space is oriented in a different direction from the gas blowing direction through the orifice.

    摘要: An antenna apparatus coupled to a feeding point arranged on a cavity is disclosed. The apparatus includes a linear element extending from the feeding point and having a physical length that is shorter than a one-quarter wavelength. A half-wave antenna element is connected to an end of the linear element. The apparatus also includes a metal conductor piece including a connecting point between the linear element and the half-wave antenna element and located close to one surface of the cavity. The linear element includes a first portion extending in a first direction opposite to that of the half-wave element from the feeding point and in parallel with one surface of the cavity and a second portion extending in a second direction, which is equal to a direction in which the half-wave antenna element extends, and in parallel with one surface of the cavity.
