Abstract: A sample inspection apparatus is provided. The invention is directed to a sample inspection apparatus 200 that includes an inspection means that is executed when a sample 11 is placed on a stage 8, the inspection means including the steps of (a) scanning a surface of the sample 11 with an electron beam EB1 with a probe 10a in contact with a conductor 11a and a probe 10b in contact with a conductor 11b, (b) measuring a differential value of a change in potential difference between the probes 10a and 10b while synchronizing with the scanning of the electron beam EB1, (c) acquiring a DI-EBAC image in which a fault spot 12 existing between the conductors 11a and 11b is shown as a bright part and a dark part based on the differential value of the change in the potential difference, and (d) specifying a direction of the fault spot 12 from the DI-EBAC image.

Abstract: Provided are an exhaust purification device and an exhaust purification method which can achieve improved fuel efficiency. The exhaust purification device (100) is equipped with: a DOC (5) for occluding hydrocarbons in an exhaust gas; a DPF (6) that is provided downstream from the DOC (5) and is for trapping particulate matter in the exhaust gas; and an ECU (10) for determining, in accordance with the amount of occluded hydrocarbons in the DOC (5), a start time for a regeneration process for removing particulate matter accumulated in the DPF (6).

Abstract: A vehicle includes an accelerator detection unit that detects an amount of depression of an accelerator pedal, brake detection units that detect depression of a footbrake pedal, vehicle speed detection units that detect a vehicle speed, and an output regulation unit that regulates an engine output when the following conditions are met: the amount of detected depression of the accelerator pedal is equal to or greater than a predetermined amount, depression of the footbrake pedal detected, and the detected vehicle speed is equal to or greater than a predetermined vehicle speed.

Abstract: An exhaust gas purification device includes an exhaust gas after-treatment device provided in an exhaust passage of an internal combustion engine, and has an oxidation catalyst and a DPF or diesel particulate filter. The exhaust gas purification device also includes an exhaust pipe injector which feeds a fuel to the oxidation catalyst, and a control unit which controls regeneration of the filter by supplying the oxidation catalyst with the fuel from the exhaust pipe injector. The control unit determines whether the filter is in a regeneration-possible state, i.e., whether the oxidation catalyst is maintained at a high temperature allowing regeneration of the filter. If the control unit determines during regeneration control of the filter that the filter is not in the regeneration-possible state, then the control unit halts the regeneration control until the regeneration-possible state is reached.

Abstract: An engine stop control device which is capable of stopping an engine without imparting an unpleasant sensation to the driver is provided. The device includes a fuel injection device for supplying fuel, an intake air amount adjustment device for adjusting an amount of intake air, an accessory controller for controlling operation of an accessory, a fuel injection controller for controlling a fuel injection amount from the fuel injection device, and an engine stop switch. When the engine stop switch is operated, driving of the accessory is stopped by the accessory controller, and the intake air is throttled by the intake air amount adjustment device, and further, when the engine rotational speed rises due to stoppage of the accessory, the engine is stopped while the fuel injection amount of the fuel injection device is controlled by the fuel injection controller such that the engine runs at a predetermined rotational speed.

An engine stop control device (8) is provided with a fuel injection device (2) for supplying fuel, an intake air amount adjustment device (3) for adjusting an amount of intake air, accessory control means (1) for controlling operation of an accessory (4), fuel injection control means (1) for controlling a fuel injection amount from the fuel injection device (2), and an engine stop switch (5).

Abstract: A welding apparatus and method for forming arc welds of thin sheet material. The apparatus forms a first pool of molten material and then discontinues the welding to permit a portion of that pool to solidify and then reestablishes a new arc at point along the periphery of the solidified previous pool and continuing this operation to form the finished weld bead. Thus, lower welding heats may be employed and greater tolerance in the welding method and apparatus is possible.
