摘要:
A liquid discharge apparatus includes a liquid discharge head, a cap, a waste liquid channel, a wiper, a cleaner, and a cleaning liquid drainage. The liquid discharge head has a nozzle, from which a liquid is discharged, on a nozzle face. The cap caps the nozzle to suck a waste liquid from the nozzle. The waste liquid channel is connected to the cap and has a waste liquid outlet from which the waste liquid is drained. The wiper wipes the nozzle face. The cleaner applies a cleaning liquid to the wiper. The cleaning liquid drainage drains the cleaning liquid applied to the wiper to the waste liquid outlet.
摘要:
A shock absorber and two packaging systems. The shock absorber is to he attached to an object to be packaged, and the shock absorber includes a first shock absorber including a first base structure having a frame shape and at least one first shock-absorbing rib disposed inside the first base structure, and a second shock absorber having a second base structure in a shape of a plate and at least one second shock-absorbing rib disposed on a plane of the second base structure. In the shock absorber, the first shock absorber and the second shock absorber are coupled to each other. One of the two packaging systems includes shock absorbers including the shock absorber, and two of the shock absorbers are used for each object to be packaged. In the other one of the two packaging systems, four of the shock absorbers are used for each object to be packaged.

A navigation apparatus comprises a map display control unit that displays a map on a display monitor, a voice information outputting unit that outputs voice information related to traveling of a vehicle, and a highlighting unit that highlights a part of the map that corresponds to the voice information in synchronization with output of the voice information by the voice information outputting unit.
摘要:
A liquid discharge apparatus includes a liquid discharger, a liquid storage, a stirrer, a plate, and a magnetic force applicator. The liquid discharger discharges a liquid. The liquid storage stores the liquid. The stirrer is rotatable in a stirring region in the liquid storage to stir the liquid in the liquid storage. The stirrer has a magnetism. The plate is secured to the liquid storage to define the stirring region. The magnetic force applicator applies a magnetic force to the stirrer from an outside of the liquid storage to rotate the stirrer.
