Abstract: A method of controlling a mobile drive unit includes detecting, by a mobile drive unit at a first location, an active marker at the first location. The mobile drive unit is a self-powered robotic device configured to move independently in a workspace in response to instructions received from the active marker. A management module transmits an instruction to the active marker. The active marker emits a signal detectable by the mobile drive unit, the signal comprising the instruction. The mobile drive unit receives the instruction from the active marker for the mobile drive unit to perform a task.

Abstract: A valve assembly is disclosed that includes a first and a second valve assembly parts that collectively define a duct. The valve assembly also includes a valve unit that includes a housing defining a fluid flow path therethrough. The valve unit is coupled to the first valve assembly part such that the fluid flow path is in fluid communication with the duct. A control valve is also included for controlling flow of fluid in the flow path. Furthermore, the valve assembly includes a sealing member that seals a space between the first valve assembly part and the second valve assembly part, that seals a space between the first valve assembly part and the valve unit, and that dampens vibration transmitted to the valve unit.

Abstract: A method of manufacturing a valve unit is disclosed that includes providing a plurality of injection molding dies that define a cavity corresponding in shape to the valve unit. The valve unit includes a housing and a valve, and the housing defines a fluid flow path with an axis having an upstream direction and a downstream direction corresponding to a predetermined direction of fluid flow in the fluid flow path. The valve is cantilevered and includes a valve body having a coupled end rotationally coupled to the housing and a free end, and the valve body rotates about the coupled end to thereby change flow through the fluid flow path. The method also includes simultaneously molding the housing and the valve within the cavity such that the valve body is formed with the free end extending away from the downstream direction of the axis of the fluid flow path.

Abstract: A valve open and close apparatus includes a resin housing, a resin valve, and a shaft. The resin housing has a fluid passage inside the housing. The resin valve has a through hole inside the valve and opens and closes the fluid passage. The shaft is press fitted inside the through hole such that the shaft is assembled to the valve. The valve includes a first shaft bearing portions, a second shaft bearing portions, and a press-fit portion. The first shaft bearing portion forms a first slide portion between the housing and the first shaft bearing portion. The second shaft bearing portion forms a second slide portion between the housing and the second shaft bearing portion. The press-fit portion is located at a position other than a radially inward portion of each of the first and second shaft bearing portions. The shaft is press fitted into the press-fit portion.

Abstract: In a manufacturing method of a fluid control apparatus, a valve integrally formed with a valve shaft is assembled inside a housing. First and second bearing members are assembled inside the housing by inserting each of the first and second bearing members into a corresponding space between the housing and the valve shaft from a corresponding longitudinal end side of the valve shaft. A longitudinal position of the valve relative to the housing is adjusted through one of the following methods. A first contact portion is brought into contact with a first side face, and a second contact portion is brought into contact with a second side face. A first contact surface is brought into contact with a first longitudinal end face, and a second contact surface is brought into contact with a second longitudinal end face.

Abstract: An in-tank type fuel pump which can easily be installed and reduces the vibration caused by the fuel pump. The fuel pumped up by a pump part passes through a filter to have foreign matter contained therein removed. Then, the fuel flows from a fuel passage, through an opening part in a cap, into a recessed part and a second fuel passage. The fuel that has flowed into the second fuel passage lifts a check valve and flows into the recessed part. Then, the fuel flows through a third fuel passage to a discharge pipe, and then is guided to the outside of the fuel tank. A ball moves within a large-diameter passage according to the fuel pressure to regulate the fuel pressure required for fuel injection. When the fuel pumping is ceased, the fuel pressure falls to 0, and therefore the ball is forced to contact a valve seat by the spring force of a compression coil spring. Then, the head part of the check valve is forced to contact a valve seat to block the fuel passage.
