20090290834 | Optical Switch - An optical switch is provided, which is used to switch a light path(s) between at least three lenses spaced from each other in a horizontal direction, or in horizontal and vertical directions. This optical switch comprises a lens supporting member for supporting the lenses, fixed prism optically coupled to the lenses, and a movable prism supported to be movable relative to the lens supporting member. The movable prism is driven by an actuator between a first position where a light path is formed between two of the lenses by use of the fixed prism and a second position where a light path is formed between another two of the lenses by use of the movable prism. | 11-26-2009 |
20100295602 | SEMICONDUCTOR RELAY - A semiconductor relay of the invention includes first and second signal terminals, a substrate, a first switch circuit and a control circuit. The substrate includes signal patterns for forming a signal line between the first and second signal terminals. The first switch circuit has a semiconductor switch used to make or break the connection between the first and second signal terminals. The control circuit has a control IC for controlling the first switch circuit. The control IC is mounted on a land of the substrate. The land has a size corresponding to the control IC. A part or all of the land is included in a part of the signal patterns. | 11-25-2010 |
