Abstract: A light emitting device includes a substrate, and a laminated structure provided to the substrate, and including a columnar part, wherein the columnar part includes a first GaN layer having a first conductivity type, a second GaN layer having a second conductivity type different from the first conductivity type, and a light emitting layer disposed between the first GaN layer and the second GaN layer, the first GaN layer is disposed between the substrate and the light emitting layer, the light emitting layer has a first well layer as an InGaN layer, the first GaN layer has a c-face region, the first GaN layer has a crystal structure of a cubical crystal, and has a first layer constituting the c-face region, and a second layer as a GaN layer having a crystal structure of a hexagonal crystal is disposed between the first layer and the first well layer.

Abstract: A molding machine is provided comprising a rotary type molding machine (1) having an injection molding portion (3) for molding a preform, an orientation blow molding portion (5) provided with a blow mold (13) which receives the preform directly or after being subjected to temperature control for molding the preform into a hollow container such as a bottle by means of an orientation blow device and, a molded product removing portion (6), and a label insertion device (20) provided adjacent the orientation blow molding portion (5). The label insertion device (20) comprises a label supply device (26) positioned to the side of the blow mold, a drive device for moving the label supply device (26) forward and backward with respect to the blow mold, and a label magazine (42) disposed between the label supply device (26) and the orientation blow molding portion (5).

Abstract: A hemodialysis system for use with any type of dialyzer, such as coil-type, Kiil-type and capillary-type or hollow fiber-type dialyzers, which has a fluid circulation circuit and a bypass circuit short-circuiting the fluid circulation circuit. At one junction between the fluid circulation circuit and the bypass circuit, an ejector is employed. The ejector has a nozzle, a diffuser axially aligned with the nozzle and defining an orifice and a suction chamber communicated with the orifice. During circulation of the dialysate in the circulation circuit and from the nozzle onto the diffuser of the ejector, a negative gauge pressure is developed in the suction chamber so that the dialysate can be drawn through the bypass circuit. The circulation circuit and the bypass circuit have respective coupling assemblies for removable connection with the coil-type dialyzer and with the Kiil-type or capillary-type, or hollow fiber-type, dialyzer.
