| 20120245496 | CHAIR-TYPE MASSAGING MACHINE PROVIDED WITH LEG MASSAGING DEVICE - In a chair-type massaging machine, when using a leg massaging device or when used as merely a chair or a sofa, it is made possible for a user to take a relaxed posture such as stretching legs forward. The leg massaging device provided in the chair-type massaging machine of the present invention is provided with an advancing and retreating mechanism. The advancing and retreating mechanism allows the leg massaging device to advance and retreat between a zero position in which the treating surface of the leg massaging device hangs down at the front end of the seat section and a second massaging position in which the treating surface is kept substantially horizontal in a massaging mode time. | 09-27-2012 |

| 20110110624 | ARRAYE WAVEGUIDE DIFFRACTION GRATING - An optical wavelength multi/demultiplexing circuit is provided in which temperature dependence at a transmission center wavelength remained in an athermalized AWG is compensated. An AWG according to an embodiment of the present invention is compensated for the main temperature dependence at the transmission center wavelength. The AWG comprises an optical splitter, a first and second arm waveguides, an optical mode combining coupler and a multimode waveguide between an input/output waveguide and a slab waveguide. The optical mode combining coupler couples fundamental mode light from the first arm waveguide as fundamental mode and the fundamental mode light from the second arm waveguide as first mode. The multimode waveguide is capable of propagating the fundamental and first mode light. This AWG is configured such that the temperature dependence remained in the arrayed waveguide grating is compensated by changing the optical path length difference between the first and second arm waveguides with temperature. | 05-12-2011 |
| 20110116802 | Optical Wavelength Multiplexing/ De-multiplexing Circuit - An optical wavelength multiplexing/de-multiplexing circuit having a low loss and a flat transmission spectrum is provided. The optical wavelength multiplexing/de-multiplexing circuit compensates a temperature dependence of a center transmission wavelength which remains in an athermal AWG, and has an excellent accuracy of the center transmission wavelength in a whole operating temperature range or has a comparatively wide operable temperature range. The temperature dependence of the transmission wavelength in the athermal MZI is modulated and set so as to cancel the temperature dependence of the center wavelength which remains in the athermal AWG. The present invention focuses particularly on an optical coupler in the MZI and modulates the temperature dependence of the transmission wavelength in the MZI by providing the optical coupler itself with a mechanism which changes a phase difference between two outputs by temperature. | 05-19-2011 |
