Abstract: A housing case for a fusion splicer is a housing case for housing the fusion splicer for an optical fiber. The housing case for a fusion splicer includes a case main body including a first side wall, and a lid body attached to the case main body to be openable and closable. The lid body includes a second side wall configured to match the first side wall when closed. At least one of the first side wall and the second side wall includes an insertion portion configured for a cable extending from the inside of the housing case to the outside thereof to be inserted through the insertion portion in a state where the lid body is closed with respect to the case main body.

Abstract: A tray for fusion splicing work is a tray used for fusion splicing work for an optical fiber, and includes a tray main body and a first body contact member. The tray main body includes a pair of long wall portions extending along a first direction, and a pair of short wall portions extending along a second direction. The first body contact member includes an outer surface configured to come into contact with a body of an operator using the fusion splicer and is attached to the tray main body on a side of one long wall portion of the pair of long wall portions. The first body contact member is able to be transitioned between an unfolded state in which the outer surface is unfolded in a third direction and a housed state in which the first body contact member is housed from the unfolded state.

Abstract: An optical fiber fusion splicer includes an image acquisition unit, a condition setting unit, and a fusion splicing unit. The image acquisition unit acquires an image including each of end surfaces of first and second optical fibers that are splicing targets in a state where the end surfaces of the first and second optical fibers are disposed to face each other. The condition setting unit sets splicing conditions in accordance with a state of each of the end surfaces by identifying the state of each of the end surfaces on the basis of the image. The fusion splicing unit fusion-splices the first and second optical fibers together by means of discharge between a pair of electrode bars in accordance with the splicing conditions set by the condition setting unit.

Abstract: Feed oil is subject to atmospheric distillation, to thereby be separated into light oil or light distillate and atmospheric residue oil. The light distillate is catalytically contacted with pressurized hydrogen in the presence of a catalyst, resulting in a first hydrotreating step being executed. In this instance, various fractions of the light distillate produced in the atmospheric distillation are subject to hydrotreating in a lump. The atmospheric residue oil is then separated into a light matter and a heavy matter. The light matter is subject to second hydrotreating in the presence of a catalyst to produce refined oil (light matter), which is mixed with refined oil produced in the first hydrotreating to prepare a mixture. The mixture is used as gas turbine fuel oil.

Abstract: A light portion is extracted from feed oil by a separation system. The light portion is then subject to a hydrotreatment to obtain impurity-removed fuel oil which is stored in an intermediate tank. A residue of the feed oil after extraction of the light portion is gasified to obtain syngas (H2 gas+CO gas) which is used as basic fuel for power generation in a power generation system. The fuel oil is fed to the power generation system as auxiliary fuel for supplementing the power generation based on the syngas. The power generation system includes a plurality of gas turbines and generators. The number of the gas turbines to be driven by the fuel oil is controlled to adjust the power generation amount depending on demand.

Abstract: A turbine rotor blades assembly is provided which can be assembled easily and which can also maintain a securely fixed circumferential relationship between top portions of adjacent turbine rotor blades during operation. The present invention provides a turbine rotor blades assembly having a plurality of turbine rotor blades fixed to the outer circumference of a turbine rotor comprising: the turbine rotor blades fixedly inserted into the turbine rotor and each including a profile member extending radially outwardly from a central axis and a top plate formed integrally with the profile member at the outer end thereof, wherein said top plate provides an abutment interconnection relationship between adjacent turbine rotor blades, wherein said abutment engaging surfaces between adjacent turbine rotor blades are slantingly angled relative to a mean straight line extending from the center of the rotor to the center of the profile member.
