Abstract: The required fuel supply amount of an internal combustion engine is reduced by limiting the throttle opening when a high-pressure fuel pump is required to discharge fuel that exceeds the fuel delivery capacity thereof. Further, when the throttle opening is limited, the operation of a return valve, through which fuel and vapor thereof can be discharged from the high-pressure fuel pump, is prohibited. By performing the abovementioned control, a reduction in the fuel delivery amount of the high-pressure fuel pump due to the operation of the return valve is prevented when there is a possibility that the fuel deliver amount of the high-pressure fuel pump runs short and the fuel supply amount of the internal combustion engine runs short.

Abstract: A media transportation mechanism has: a storage unit that stores disc-shaped media with a center hole in a stack; a transportation arm that moves vertically and has a gripping member to hold a medium stored in the storage unit, and a separating member that moves radially to the medium from the hole of the medium; and a transportation arm drive member that sets the ascent speed of the transportation arm to a first speed, and to a second speed that is slower than the first speed, when moving the transportation arm vertically up while the gripping member holds the medium.

Abstract: A tractor unit has first and second tractors with tractor pins that engage sprocket holes on opposites sides of continuous paper. A tractor support shaft supports the tractors movably in the device width direction. A frame supports the tractor support shaft movably in the device width direction. A clamping mechanism is provided for fixing the second tractor on the tractor support shaft. The first tractor 31 is disposed at a reference position in the device width direction. A biasing member biases the tractor support shaft in a second direction when the tractor support shaft moves in a first direction opposite to the second direction.

Abstract: A method for manufacturing a contact probe includes: a lithography step of obtaining a resin mold by forming a pattern for the contact probe, a pattern for a tie bar in a shape of a frame therearound, and a pattern for a coupling portion coupling these two patterns, in a resist formed on a conductive substrate, by lithography; an electroforming step of forming a layer made of a metal material on the resin mold by electroforming to form a metal structure in which the contact probe is integral with the tie bar at the coupling portion; a removal step of removing the resin mold and the conductive substrate; a plating step of forming a plating layer on a surface of the metal structure by electroplating after the removal step; and a separation step of separating the contact probe from the metal structure after the plating step.

Abstract: A contact probe, a method of manufacturing a linked body of contact probes, and a method of manufacturing a contact probe, which allow for stable use are provided. Contact probe includes a contact portion to be brought into contact with an object to be measured, a main body portion connected to the contact portion, and a covering portion covering the whole circumference of a cross section of the main body portion in a direction intersecting with an extensional direction, excluding the contact portion. The covering portion is of a material having a lower volume resistivity than a volume resistivity of a material of the main body portion.

Abstract: The invention offers an electrode member for a cold cathode fluorescent lamp, the member having excellent ability to attain intimate contact between the lead portion and glass, and a production method thereof. The electrode member 10 has an electrode portion 11, a lead portion 12, and a glass portion 13. The lead portion 12 is formed such that at least its surface side is composed of an iron-containing metal. The lead portion 12 has on its surface an oxide film 12s at the place covered by the glass portion 13. The oxide film 12s contains FeO. In comparison with an oxide film composed of Fe2O3 and Fe3O4, the oxide film 12s containing FeO tends to have great ability to attain intimate contact with glass. Consequently, the electrode member 10 can bring the lead portion 12 into sufficient intimate contact with the glass portion 13, enabling the constituting members from the lead portion 12 to the glass tube of the cold cathode fluorescent lamp to attain sufficient intimate contact between them.

Abstract: In an engine including an in-cylinder injector and an intake manifold injector, the fuel injection ratio between the injectors with respect to a total fuel injection quantity in the homogeneous combustion operation is normally set in accordance with the engine operation state (engine speed, load factor). Upon transition from the stratified charge combustion operation to the homogeneous combustion operation, the fuel injection ratio is modified from that of the normal operation during a prescribed control period so that the fuel injection quantity from the intake manifold injector is increased than in the normal operation state, considering that the fuel newly injected via the in-cylinder injector immediately after transition of operation mode is likely to deposit inside the combustion chamber because of the fuel deposited therein during the stratified charge combustion operation. This prevents combustion deterioration in the engine upon transition of the operation mode.

Abstract: The engine ECU executes the program including the step of starting a timer that counts the time elapsed from a start request, the step of detecting a temperature of the engine, and the step of calculating a DI ratio r such that the fuel is injected from the in-cylinder injector as well, when the engine is in the very cold or cold state, when there is no abnormality in the fuel system, and when starting of the engine is not yet detected even after a lapse of a predetermined period of time from the start request, only if the fuel pressure in the high-pressure system is not lower than a fuel pressure threshold value.

Abstract: A driving force generated by an engine is transmitted to driving wheels (not shown) via an automatic transmission. The engine is provided with an electronically controlled throttle body and the like. An E-ECU performs cooperative control when necessary, so that an output of the engine is obtained in accordance with a load applied thereto. On the other hand, the automatic transmission is provided with a torque converter. Even in the case where the aforementioned predetermined condition has been fulfilled in a T-ECU, if the E-ECU detects a deterioration in performance of the electronically controlled throttle body or the like, the performance of neutral control is prohibited.
