Provided is A method of manufacturing diesel fuel, including: fractionating in a first fractionator a synthetic oil obtained by Fisher-Tropsch synthesis into at least two fractions of a middle fraction, and a wax fraction containing a wax component heavier than the middle fraction; hydroisomerizing the middle fraction by bringing the middle fraction into contact with a hydroisomerizing catalyst to produce a hydroisomerized middle fraction; hydrocracking the wax fraction by bringing the wax fraction into contact with a hydrocracking catalyst to produce a wax decomposition compound; fractionating in a second fractionator a mixture of the hydroisomerized middle fraction and the hydrocracked wax fraction into at least two fractions including a kerosene fraction and a gas oil fraction; and mixing the at least two fractions at a predetermined blend ratio to produce a diesel fuel having a kinematic viscosity at 30° C. of 2.5 mm2/s or more and a pour point of −7.5° C. or less.
摘要:
When VOB recording has reached the vicinity of the end position P6 of a first layer recording area (43), a cell close instruction is issued to stop encode processing for forming the next VOB to be stored. At this moment, for forming the next VOB to be recorded, content data stored in a buffer memory (18A) is used to form a VOB having, for example, a shorter length than a normal VOB. The VOB is recorded in the end position of the first layer recording area. After this, a dummy cell, having dummy data is recorded in an unrecorded area (122) of the end portion of the first recording area.

An exhaust system for a motorcycle includes a plurality of exhaust pipes connected respectively to exhaust ports of cylinders of a multi-cylinder engine; a manifold portion connected to the exhaust pipes; and a muffler connected to a downstream side of the manifold portion, the manifold portion being disposed below the engine, wherein the manifold portion is disposed sideways of an oil pan disposed below the engine so as to overlap the oil pan when seen in a side view of the motorcycle, and the exhaust pipes are connected to the manifold portion from a front side of the motorcycle.
摘要:
A headrest control apparatus includes: a headrest moving mechanism that supports a headrest in such a manner that at least one of a rotation of the headrest about an axis of the headrest, which extends in the vehicle-height direction, and a movement of the headrest in the vehicle-width direction is permitted; a drive unit that causes at least one of the rotation and the movement of the headrest; and a control unit that controls the drive unit.
摘要:
The present invention provides pulsed lasers which employ carbon nanotubes, particularly layers of carbon nanotubes, as saturable absorbers, mode lockers or for Q-switching elements. The present invention also provides methods and materials for mode-locking and Q-switching of lasers in which carbon nanotubes are employed as non-linear optical materials and/or saturable absorbers which facilitate mode-locking and/or Q-switching. The invention further provides mode locker and Q-switching elements or devices which comprise one or more layers containing carbon nanotubes which layer or layers function for mode locking and/or Q-switching.
摘要:
Non-linear optical characteristics of a carbon nanotube are applied to an optical communication field. An optical transmission medium (12) obtained by incorporating a carbon nanotube having optically non-linear characteristics into a non-linear light transmitting medium is assembled between typical optical transmission medium (14a, 14b) and is used by being combined with an optical circulator (16), whereby the resultant product is used as an optical fuse (breaker) that transmits a normal signal light A but blocks the transmission of an abnormal-intensity light inadvertently produced.
