Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.

Abstract: A method for producing a resin sintered body 1 by applying an ink 3 to thermoplastic resin powder 2 and sintering the powder, the method including the step of immersing an intermediate resin sintered body 1m, which has an unevenly colored region on the surface thereof and the whole of which has been already sintered, in a surface treatment liquid containing sulfuric acid and chromic anhydride, in which the concentration of chromic anhydride is 300 g/L or more, for 5 minutes or longer. When producing a resin sintered body by sintering thermoplastic resin powder, the surface of the resin sintered body can be evenly and sufficiently colored to an extent required without an unevenly colored region on the surface thereof, and also the surface of the resin sintered body can have a good appearance and smoothness.

Abstract: A tractor includes a working motor, a work machine including a roller configured to rotate by an output from the working motor, a support mechanism configured to support the work machine such that a working posture and a retracting posture are achievable, and a control device. The control device executes: an adherence amount acquisition process of acquiring an estimated adherence amount as an estimated value for the amount of mud attached to the roller; and a mud removal process of, when the estimated adherence amount is equal to or more than a determination adherence amount, removing the mud from the roller by driving the working motor in a state where the work machine takes the retracting posture.

Abstract: An evaporation unit includes a first and second pipe conduits. The first and second pipe conduits each include a near-end part, a long circumference part, a junction part, a short circumference part, and a far-end part. Around a storage chamber, the first long circumference part extends in a first direction, the first junction part turns, and the first short circumference part extends in the first or second direction. The second short circumference part extends in the first direction, the second junction part turns, and the second long circumference part extends in the first or second direction. The first and second turning part located at the same position counted from the respective near-end part sides are disposed respectively on wall surfaces facing each other.

Abstract: A sealing member that forms a combustion gas flow path of a gas turbine includes a first body portion having a cooling passage. The first body portion includes a first end portion forming one end portion in a circumferential direction, a second end portion forming the other end portion on an opposite side in the circumferential direction, and an intermediate portion formed between the first and second end portions. The cooling passage includes an intermediate portion cooling passage inclined at a first angle with respect to an axial direction, a first end portion cooling passage provided in the first end portion and inclined at a second angle with respect to the axial direction, and a second end portion cooling passage provided in the second end portion and inclined at a third angle with respect to the axial direction, and the second and third angles are smaller than the first angle.

Abstract: The fuel cell system includes a fuel cell, a first injection device associated with a supply of a fuel to the fuel cell, and a second injection device provided on an upstream side of the first injection device in a fuel flow passage from a fuel storage unit to the first injection device. The first and second injection devices switch a flow passage extending downstream from the fuel flow passage, between a first flow passage via the first injection device and second flow passage via the second injection device. The second injection device operates at a lower frequency than the first injection device during an operation of the fuel system.

Abstract: A vehicle brake system includes a first fluid pressure generating device for generating a fluid pressure according to a brake operating amount, a second fluid pressure generating device for generating a fluid pressure by moving a piston with an electric actuator, and a switching valve switchable between a first state allowing communication between the first fluid pressure generating device and a vehicle behavior stabilizing device and a second state allowing communication between the second fluid pressure generating device and the vehicle behavior stabilizing device. A control device places the switching valve in the second state during execution of automatic brake control, and places the switching valve in the first state when a predetermined abnormality occurs in the vehicle, except that the control device places the switching valve in the second state when an abnormality including inability of the second fluid pressure generating device to generate the fluid pressure occurs.

Abstract: A coil component includes a drum core including a winding core portion extending in a first direction and a pair of flange portions provided at both ends of the winding core portion. At least one flange of the pair of flange portions has at least one step or gradient portion. A terminal electrode is provided on the step or gradient portion, and a wire is wound around the winding core portion with an end bonded to the terminal electrode.

Abstract: An image forming apparatus includes a first unit including an image bearing member and a second unit. The second unit includes a developing roller to supply the toner to the image bearing member, a mounting portion in which the replenishing container is dismountably mounted and an accommodating portion to accommodate the toner replenished from the replenishing container. The second unit is movable between a first position where the developing roller contacts the image bearing member and a second position where the developing roller separates from the image bearing member. When a moving direction in which the second unit moves from the first position toward the second position is defined as a separating direction, the second unit is urged in the separating direction by a force which the mounting portion receives from the replenishing container when the replenishing container is mounted to the mounting portion.
