A liquid ejecting apparatus includes a liquid ejecting head having a nozzle, a pressurizing chamber that communicates with the nozzle, and a pressurizing element that causes a pressure change in liquid within the pressurizing chamber, the liquid ejecting head being capable of ejecting liquid from the nozzle by operating the pressurizing element; and a driving signal generation unit that generates a driving signal including a driving pulse that drives the pressurizing element. The driving signal includes an ejection driving pulse that ejects a liquid droplet and a non-ejection driving pulse that drives the pressurizing element to a degree whereby a liquid droplet is not ejected. The ejection driving pulse is a pulse waveform having an expansion element that causes the pressurizing chamber to expand and retract a meniscus toward the pressurizing chamber and a constriction element that causes the pressurizing chamber expanded by the expansion element to constrict and push the meniscus in the direction of ejection. The non-ejection driving pulse is a pulse waveform having an expansion element that causes the pressurizing chamber to expand and retract the meniscus toward the pressurizing chamber, a holding element that holds the voltage at the end of the expansion element for a set amount of time, and a constriction element that causes the pressurizing chamber expanded by the expansion element to constrict and push the meniscus in the direction of ejection. When the length of time from the end of the constriction element in the ejection driving pulse to the beginning of the expansion element in the non-ejection driving pulse is taken as t, the lengths of time of the expansion element, holding element, and constriction element in the non-ejection driving pulse are taken as a, b, and c, respectively, and the inherent vibration cycle of the liquid within the pressurizing chamber is taken as Tc, t, a, b, and c are within the ranges defined by the following equations (1) through (3): Tc/4≦t≦Tc/2 (1) (5Tc/8)−t≦a≦(3Tc/4)−t (2) b+c=Tc−t−a (3)

This invention improves response by preventing a steady-state difference and a disturbance from occurrence even when the volume of a pressure chamber of an air cylinder varies dramatically. In a method for controlling an air cylinder such that air is supplied to and exhausted from pressure chambers of the air cylinder by air servo valves; pressures in the pressure chambers are detected by pressure sensors; signals of the detected pressures are feedback to a controller; and the degrees of opening of the air servo valves are adjusted by corresponding PID adjusters of the controller on the basis of the respective differences between instruction values and detection values, the displacement of the rod of the air cylinder is detected by a displacement sensor, and a detection signal of the displacement is fed back to the controller so that a gain of the PID adjuster is always changed in accordance with the detection signal of the displacement.

A caster for a baby carriage is composed of: a caster holder mounted to a front leg of a baby carriage; a caster column provided at the caster holder and having a flange-shaped portion at its lower end, wherein the caster bearing member is slidably and rotatably mounted relative to the caster column and supports a front wheel at one side. Tapered surfaces that are inclined toward a circumferential direction and engage each other are provided on a top surface of the flange-shaped portion of the caster column and a downwardly directed surface of the caster bearing member, respectively. A spring is provided between the caster holder and the caster bearing member to force the caster bearing member in a direction toward the flange-shaped portion of the caster column.

A stroller has a body structure adapted to be unfolded into an unfolded state for use, and to be folded into a folded state. A handle is supported on the body structure for forward and backward turning. The handle is set in either a backward-inclined position for a back-faced pushing mode or a forward-inclined position for a front-faced pushing mode. A handle locking mechanism locks the handle in the backward-inclined position for the back-faced pushing mode via a stopping member and a back stopping projection that engages with the stopping member. When the body structure is folded and armrests are turned upwardly from a working position, the stopping projection, which is fixed to the armrest, turns relative to the stopping member and an end part of the stopping projection is located with its major axis extended perpendicularly to an axis of the handle, and with a part thereof lying in a groove. When the stroller is folded, the end part engages with a stepped part formed in the groove to restrain the stopping member from upward movement, i.e. movement in an unlocking direction.
