An opto-electrical hybrid board () of the present invention has an optical waveguide (), an optical connector disposed at an end section of the optical waveguide (), and an opto-electric conversion section () disposed below the optical waveguide (), and a motherboard (electrical wiring board) () disposed below the opto-electric conversion portion (). Of these, the optical waveguide () includes a core layer () including a plurality of core sections () being configured to intersect with each other at one plane and side surface cladding sections, and a mirror (optical path conversion section)converting the optical path of the core sections (). Also, between the optical waveguide () and the motherboard () is connected via an electrical connector and preferably both the optical waveguide () and the motherboard () are detachable.

Optical waveguide, optical interconnection component, optical module, opto-electric hybrid board, and electronic device

The temperature control system is provided with a lower heat removing unit which is disposed at the bottom of a reactor inside which an exothermic reaction takes place and through which a liquid coolant is flowed, and an upper heat removing unit which is disposed in the reactor further above from the lower heat removing unit and through which the liquid coolant is flowed, recovering reaction heat inside the reactor and controlling a temperature inside the reactor. The lower heat removing unit is supplied with the liquid coolant which is adjusted for temperature by a first temperature adjustment unit, and the upper heat removing unit is supplied with the liquid coolant which is adjusted for temperature by a second temperature adjustment unit different from the first temperature adjustment unit.

Temperature control system, hydrocarbon synthesis reaction apparatus, hydrocarbon synthesis reaction system, and temperature control process

The hydrocarbon production apparatus is provided with a gas-liquid separator for cooling gaseous state hydrocarbons drawn out from a gas phase portion of a reactor for the Fischer-Tropsch synthesis reaction and liquefying a portion of the hydrocarbons. A light liquid hydrocarbon supply line for supplying light hydrocarbons is disposed between a downstream side line which is downstream from the last stage of a gas-liquid separating unit of the gas-liquid separator, and an upstream side line which is upstream from the last stage of the gas-liquid separating unit of the gas-liquid separator, wherein the downstream side line is a liquid hydrocarbon line on the downstream side through which the light hydrocarbons having cloud points lower than the temperature at an outlet of a cooler in the last stage of the gas-liquid separating unit are flowed.

Hydrocarbon production apparatus and hydrocarbon production process

The method for stopping operation of a reactor is provided with a stop step of stopping supply of a synthesis gas containing a carbon monoxide gas and a hydrogen gas into the reactor; a slurry discharge step of discharging slurry from the reactor; a steam supply step of supplying steam higher in temperature than the decomposition temperatures of metal carbonyls into the reactor, thereby discharging gaseous matters inside the reactor; and a carbon monoxide gas detecting step of detecting an amount of carbon monoxide gas contained in the gaseous matters discharged from the reactor. In the steam supply step, supply of the steam is stopped when an amount of the detected carbon monoxide gas continuously declines to be lower than a predetermined reference value.
