    摘要: A surface emitting semiconductor laser includes an active region formed on a growth substrate, upper and lower mirror layers that sandwich the active region to construct a vertical cavity, a selective oxidization layer, and a current injecting unit for injecting a current into the active region. The selective oxidization layer is selectively oxidized and insulated and is provided on the side of the active region opposite to the side of the substrate. In this structure, a post portion is formed by removing semiconductor material formed on the substrate down to an uppermost or halfway level of the selective oxidization layer while the selective oxidization layer is used as an etch stop layer, and the selective oxidization layer acts as both a current confinement layer for the current injection and an insulating layer for the current injecting unit.

    摘要: A local air cleaning apparatus (1) is provided with a push hood (2) having an air flow opening face (23) for blowing out a cleaned uniform air flow and a guide (3) provided on a side of the push hood (2) having the air flow opening face (23), the guide (3) extending from the side thereof having the air flow opening face (23) toward a downstream side of the uniform air flow to form an opening face (31) at a downstream end portion thereof. The push hood (2) is arranged such that the uniform air flow blown out from the air flow opening face (23) passes through the inside of the guide (3) and then collides with an air collision face (W) on a downstream side of the opening face (31). The opening face (31) of the guide (3) is spaced apart from and opposed to the air collision face (W) to form an open region between the opening face (3) and the air collision face (W). The cleaned uniform air flow blown out from the air flow opening face (23) collides with the air collision face (W) and flows out of the opening region, thereby allowing the inside of the guide (3) and the inside of the open region to have higher cleanliness than other regions.

    摘要: In the laminated coil component, the grain diameter of the coil conductors is 10 μm to 22 μm after baking is completed. When the grain diameter of the coil conductors is set to be 10 μm or larger after baking is completed, surface roughness of the coil conductors can be reduced to such an extent that a satisfactory Q value can be obtained at a high frequency. In addition, when the grain diameter of the coil conductors is set to be 22 μm or smaller after baking is completed, metal of the coil conductors can be refrained from being rapidly melted down during baking. Accordingly, a high Q value can be obtained while a high quality is ensured.
