An optical semiconductor device with a multiple quantum well structure, is set out in which well layers and barrier layers, comprising various types of semiconductor layers, are alternately layered. The apparatus allows a multiplicity of capsule shells all to be concurrently oriented in an upright disposition by a manually operated mechanism. The memory stores weather radar return information in a three-dimensional buffer. An interworking server connected between the access point of the wireless LAN system and the packet control function of the mobile communication system. The method includes determining a characteristic and a characteristic value of the parts of the product variant and generating a variant demand object for the product variant.
