摘要:
Silencing equipment provided with one or more flow channels through which cooling air flows has a flow channel forming member that forms the flow channel, and an acoustic absorbent member that is fixed to the flow channel forming member. A resonance type silencer is formed on a wall surface of the flow channel by providing a cavity for the resonance type silencer in the acoustic absorbent member and an aperture for the resonance type silencer in a portion of the flow channel forming member. The resonance type silencer sets a frequency of noise necessary to be reduced based on a peak frequency of noise generated by a fan. The silencing equipment further has a slide member which slides by a slide mechanism to adjust the area of the top of the aperture. The silencing equipment for electronic devices capable of cooling heat generating sections thereof with air has a small and simple structure and can improve a silencing effect by blowing air.

The present invention aims at providing a sputtering system capable of efficiently generating high-density plasma near the surface of a sputter target and forming a film at a high rate. It also aims at providing a large-area sputtering system and a plasma processing system having a simple structure and allowing the sputter target to be easily attached/detached, maintained, or operated otherwise. The present invention provides a sputtering system in which an inductively-coupled antenna conductor plate is attached to a portion of a vacuum chamber, wherein: a sputter target plate is attached to the inductively-coupled antenna conductor on its plasma formation space side; one end of the antenna conductor is connected to a radio-frequency power source; and the other end is grounded through a capacitor. A plurality of antenna conductors may be provided to form a large-area sputtering system.

In a semiconductor laser device of the invention, a ridge portion 150 forms a waveguide, and guided light goes along the ridge portion 150. A tail of the guided layer is present also at first side portions 151, while second side portions 152 are regions which the tail of the guided light does not reach. Meanwhile, scattered light generated from the ridge portion 150 goes through the first side portions 15, spreading into the second side portions 152. In the second side portions 152, a light absorption layer 127 serving as a light absorber is formed on the first upper clad layer 108, where the scattered light is absorbed. As a result of the absorption of scattered light in the second side portions 152, ripples of radiation light are reduced. Also since the light absorption layer 127 is in electrical contact with a p-side ohmic electrode 125, the problem of charge accumulation to the light absorption layer 127 can be avoided.

摘要:
An AlGaInP based window structure semiconductor laser device of the present invention has an optical waveguide in which a lower cladding layer, an active layer having a quantum well layer, and an upper cladding layer are laminated in this order and which emits light from a light-emitting end surface that is formed on an end of the optical waveguide. A window portion having an active layer in which the quantum well layer is disordered is formed in an end portion including the light-emitting end surface in the optical waveguide. A light intensity distribution in a vertical direction for the laminated layers in the window portion spreads further than a light intensity distribution in the vertical direction in a non-window portion which is adjacent to the window portion inside the optical waveguide. A length of the window portion from the light-emitting end surface to the non-window portion is not smaller than 48 μm and not greater than 80 μm.
