| 20110052189 | OPTICAL DEVICE FOR REARRANGING WAVELENGTH CHANNELS - An optical device for rearranging wavelength channels in an optical network is disclosed. The optical device has a wavelength selective coupler having one input port and a plurality of output ports coupled to a plurality of input ports of an optical grating demultiplexor such as an arrayed waveguide grating. The wavelength channels in each of the input ports are dispersed by the demultiplexor and are directed to a plurality of output ports of the optical grating demultiplexor. As a result, at least one wavelength channel at each of the input ports of the optical grating demultiplexor is coupled into a common output port. The optical device is useful in passive optical networks wherein a same demultiplexor is used for simultaneous multiplexing and demultiplexing of wavelength channels. | 03-03-2011 |

| 20110026407 | CONTROLLER - This invention enables an abnormality analysis to be easily and reliably performed in the FA system of the EtherCAT (registered trademark). A controller has a protocol monitor function of operating in a monitor system program, and constantly monitors data communicated with a remote device. The controller has an abnormality diagnosis function of detecting abnormality, and thus holds the data monitored immediately before when abnormality is detected. As the protocol monitor function is incorporated, a protocol monitor does not need to be newly plugged into the network as an external device after the occurrence of abnormality, and the data that becomes the cause can be held from the abnormality that occurred first by monitoring from the beginning of the operation of the system and can be used for analysis. | 02-03-2011 |

| 20110011516 | PROCESS FOR PRODUCING CERAMIC SUBSTRATE - A shrinkage suppression layer used in the production of a ceramic substrate according to a non-shrinkage process provides favorable removal performance while sufficiently ensuring the restraining performance of the shrinkage suppression layer. Resin beads, which disappear at a temperature lower than the sintering temperature of a low-temperature sintering ceramic material of a base material layer to form open bores in a shrinkage suppression layer, are added to the shrinkage suppression layer and dispersed uniformly at least in a principal surface direction. The shrinkage suppression layer provides sufficient restraining performance to the base material layer in the step of firing, and after the firing, forms open bores, thereby improving the removal performance of the shrinkage suppression layer. | 01-20-2011 |
