A liquid discharger includes a head to discharge liquid droplets, a cap to cover a nozzle face of the head; a cap mover to move the cap to a capping position at which the cap faces the nozzle face of the head or to move the cap to an evacuation position at which the cap does not face the nozzle face of the head. Further, there is a belt arranged to face and clean the cap at the evacuation position, the belt having a width and length enough to cover whole area of a rim of the cap; a conveyer to drive the belt, and a belt cleaner which faces the belt to clean the belt.

A liquid stirrer includes a removable first liquid container to contain a liquid; a second liquid container having a capacity less than that of the first liquid container; a fluid path between the first liquid container and the second liquid container; a reversible pump disposed on the fluid path; a sensor to detect an amount of the liquid inside the second liquid container, in which the liquid reciprocally moves between the first liquid container and the second liquid container; and a controller to control the reversible pump, based on readings from the sensor, such that a moving amount of the liquid does not exceed the capacity of the second liquid container and that the second container does not go empty.

A waste liquid collection unit is located over a print medium in a discharge direction of a liquid discharge head. The collection unit includes an absorber; a tray housing the absorber exposed to a nozzle surface of the head; and a pressing member to press the absorber toward a bottom surface of the tray. The pressing member includes a base material extending in an alignment direction of nozzles and end members connected to ends of the base material and displaceable to be biased to an inner wall surface of the tray in an axial direction when the pressing member is placed in the tray. The end members include a first fitting portion in a surface facing the inner wall surface. The tray includes a second fitting portion in the inner wall surface. The first and second fitting portions are fitted when the pressing member is placed in the tray.

A liquid discharger includes a head including nozzles to discharge liquid from the nozzles, a detachable first container attached to the liquid discharger to accommodate the liquid, a second container connected to the head to accommodate the liquid to be supplied to the head, a supply channel to connect the first container and the second container, an irreversible pump connected to the second container, and a controller to control the irreversible pump to pressurize and decompress the second container to reciprocally move the liquid between the first detachable container and the second container via the supply channel.

A method and apparatus for inserting a first member into a hole of a second member includes the steps of (a) inclining either of the first member or the second member relative to the other and offsetting a center of the first member and a center of the hole, (b) moving the first member and the second member toward each other so that the first member and the second member contact each other at one point and are biased against each other, and (c) rotating either the first member or the second member about the contact point in a direction such that the center of the first member and the center of hole approach thereby inserting automatically the first member into the hole.

A relief device includes a relief housing constituted by a relief inflow portion, a valve passage portion, a recess, and an oil discharge portion having a relief hole; a relief valve having a small-diameter portion between a first large-diameter portion and a second large-diameter portion; and a spring elastically biasing the relief valve toward the relief inflow portion. The recess is formed at a position that is closer to the relief inflow portion side than to the oil discharge portion, the axial length of the recess is larger than the axial length of the first large-diameter portion of the relief valve, and the shortest axial distance between the recess and the relief hole is less than the axial length of the small-diameter portion.

A machined shape of a bore is based on the deformation amount of a data-acquisition bore after fastening of cylinder head. A cross section of an approximate shape is set to be an approximately-true circle shape, and a diameter of the approximately-true circle shape is changed along a central axial direction in accordance with the deformation amount of the data-acquisition bore, to determine the approximate shape. The approximate shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis. Since the machined shape of the bore is the shape obtained by reversing a phase of a recess and a projection of the approximate shape about a predetermined cylindrical shape, the machined shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis.
