A solid oxide fuel cell system includes: an igniting portion (8) configured to ignite a raw material when starting up the solid oxide fuel cell system; a raw material supply portion (10) configured to supply the raw material; a reforming air supply portion (11) configured to supply reforming air; and an electric power generation air supply portion (12) configured to supply electric power generation air. When starting up the solid oxide fuel cell system, the raw material supply portion (10) supplies the raw material, and the electric power generation air supply portion (12) supplies the electric power generation air. The igniting portion (8) ignites the raw material. After the ignition, the preforming air supply portion (11) supplies the reforming air. With this, the safety can be increased in consideration of characteristics in respective phases from the start-up of the solid oxide fuel cell system until the electric power generation.

A toilet device includes a toilet seat device, a radio wave sensor, and a controller. The toilet seat device is provided on a toilet bowl. The controller is configured to operate the toilet seat device based on a signal outputted from the radio wave sensor. The radio wave sensor is being operable for detecting presence of a human body in a first area including front of the toilet seat device, detecting motion of a human body in a second area including the front of the toilet seat device and a region outside the first area, and determining sensing of the human body based on detection result of the motion of the human body and detection result of the presence of the human body.


A composite structure formation method includes the steps of storing a plurality of pre-formed controlled particles in a storage mechanism, supplying the controlled particles from the storage mechanism to an aerosolation mechanism constantly, disaggregating the supplied controlled particles into a plurality of the fine particles in the aerosolation mechanism to form an aerosol in which an entire contents of the controlled particles including the fine particles are dispersed in the gas; and spraying all of the fine particles in the aerosol toward the substrate to form a composite structure of the structure and the substrate. The controlled particles are controlled so that bonding strength between the fine particles includes a mean compressive fracture strength sufficient to substantially avoid disaggregation during the supply step, but which permits the controlled particles to be substantially completely disaggregated in the disaggregation step.

According to an aspect of the invention, an optical receptacle, comprising: a fiber stub including an optical fiber, a ferrule, and an elastic member, the optical fiber including cladding and a core for conducting light, the ferrule having a through-hole fixing the optical fiber, the elastic member being filled into the through-hole of the ferrule with the optical fiber; and a holder holding the fiber stub, the through-hole of the ferrule including a small diameter portion and a large diameter portion, the optical fiber being disposed in the small diameter portion, the large diameter portion being provided on a side opposite to a side to be optically connected to a plug ferrule, the optical fiber being disposed in the small diameter portion inside the through-hole of the ferrule over the entire region of the optical fiber, the elastic member having substantially the same refractive index as the core, being filled into the small diameter portion and the large diameter portion, and being polished to cause at least a portion of the elastic member to be a flat surface portion at an end surface of the fiber stub on the side opposite to the side to be optically connected to the plug ferrule. By disposing the optical fiber in the small diameter portion of the through-hole of the ferrule over the entire region of the optical fiber, the breaking and/or cracking of the optical fiber and the decrease of the coupling efficiency can be prevented. Further, by setting the end surface of the elastic member filled into the through-hole of the ferrule to be a flat surface, the decrease of the coupling efficiency due to reflections is prevented without performing processing of the optical fiber end surface; and economic production is made possible.
