摘要:
An attachment method attaches a bracket to a vehicle, and attaches a radar to the bracket so that an axis of a directivity pattern of an antenna directs upward with respect to a horizontal direction. The antenna of the radar has an asymmetric vertical directivity pattern with respect to the axis of the directivity pattern.

The gas oil fraction hydrotreatment process of the invention is characterized by using a hydrorefined petroleum-based hydrocarbon oil with a sulfur content of 5-15 ppm by mass, a total aromatic content of 10-25% by volume and a boiling point range of 150-380° C. as the feed oil and subjecting the feed oil to hydrotreatment in the presence of a hydrogenation catalyst to obtain an ultralow sulfur and low aromatic gas oil fraction having a sulfur content of not greater than 1 ppm by mass and a total aromatic content of not greater than 1% by volume. This hydrotreatment process allows production of a “zero sulfur” and “zero aromatic” gas oil fraction in an efficient and reliable manner without provision of special operating conditions or equipment investment.

A fish processing machine includes a fish body feeder, a decapitator, a belly filleting and viscera removing device, and a dark-colored flesh removing device. The fish body feeder is designed to transport fish bodies onto trays while aligning all of the fish bodies in a uniform direction. The dark-colored flesh removing device separates the ordinary flesh and dark-colored flesh of the fish body efficiently.
摘要:
A control system for an automatic transmission apparatus for vehicle in which, when an instruction signal to start a speed shift is generated, the engaging force of one engaging element to be released is controlled so that the rotation speed of the input shaft is regulated to be equal to a predetermined reference rotation speed higher that the rotation speed before the generation of the instruction signal and, after an effective shift is detected, the engaging force of the other engaging element to be engaged is controlled so that the changing rate of the rotation speed of the input shaft converges to a predetermined reference changing rate, thereby preventing simultaneous complete engagement of both engaging elements and accomplishing a smooth change-over of the torque transmission path.
摘要:
A ductile cast iron having a high tensile strength as well as a high elongation due to its matrix structure of finely mixed ferrite and pearlite grains obtained by the heat treatment. The material is pearlitic ductile cast iron and may be of ordinary ductile cast iron composition with the only exception that the manganese content being substantially less than 1%.A method of heat treatment for obtaining such a ductile cast iron, which is composed substantially of heating the material rapidly to form ferrite, austenite and graphite co-existing structure, and air cooling the same to change that structure into the above mentioned matrix structure.

A nuclear power plant control system (1) includes a control button (21) which receives an operation for controlling a control target device (40), a notification lamp (12) which notifies that a control signal corresponding to the operation received by the control button (21) arrives at a predetermined position on a path connected from a control panel (20) to the control target device (40), and a control signal inhibition unit (33) which inhibits a control signal from arriving at the control target device (40) in midstream between the predetermined position on the path and the control target device (40) in response to an operation received by a test permission button (11).
摘要:
A method for starting-up a naphtha fraction hydrotreating reactor which subjects a naphtha fraction obtained in a fractionator by fractional distillation of hydrocarbon compounds produced by a Fischer-Tropsch synthesis reaction to hydrotreating, the method comprising: charging in advance an inactive hydrocarbon compound corresponding to the naphtha fraction into a vapor-liquid separator to which hydrogenated naphtha, which has been subjected to hydrotreating in the naphtha fraction hydrotreating reactor, is transferred; mixing the inactive hydrocarbon compound drawn from the vapor-liquid separator and the naphtha fractions being transferred from the fractionator to the naphtha fraction hydrotreating reactor, and supplying a mixture of the naphtha fractions and the inactive hydrocarbon compound to the naphtha fraction hydrotreating reactor.

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:
A throttle opening detection apparatus can include a throttle pipe, a throttle sensor, a resisting force application unit, and a cancel switch. The throttle pipe is configured to partly project into a case fixed to a bar handle and is configured to support rotation at an end portion of the bar handle. The throttle sensor is configured to detect a rotating operation amount of a throttle grip, which is mounted against relative rotation on the throttle pipe, in response to the rotation of the throttle pipe. The throttle sensor is disposed at a fixed position in the case. The resisting force application unit is configured to apply a resisting force to the rotating operation of the throttle grip. The resisting force application unit is accommodated in the case. The cancel switch configured to cancel operation of an auto-cruise controlling apparatus. The cancel switch is accommodated in the case together with the throttle sensor and the resisting force application unit.
