摘要： A rotary driving source is connected to one end of a frame. The rotary driving force of the rotary driving source is transmitted to a slider by the aid of a driving pulley, a belt member, and a driven pulley. The slider is displaced in the axial direction of the frame while being guided by a guide mechanism. Each of the frame and the slider is formed of, for example, an aluminum alloy. First guide rails are installed in the frame and second guide rails are installed in side surfaces of the slider. The first guide rails and the second guide rails are formed of a metal material subjected to a hardening treatment.

摘要： An actuator comprises a pump-driving section which is driven and rotated by a current, and a pump mechanism which is connected to the pump-driving section and which sucks/discharges a pressure oil. A cylinder mechanism, which has a piston that is displaceable in the axial direction by being supplied with the pressure oil, is provided on the pump-driving section and the pump mechanism. The amount of discharge of the pressure oil to the cylinder mechanism is adjusted by freely changing the angle of inclination of a tilting member provided in the pump mechanism.

摘要： A load of a workpiece, which is applied to a slider (68), is supported by guide blocks (78) and guide rails (30a, 30b) provided for a frame (12). On the other hand, pin members (72), which constitute a floating mechanism (64) provided under the slider (68), are slidably engaged with fitting members (66) installed to recesses (62) of a projection (54). Therefore, a ball screw (16) is prevented from any application of the load of the workpiece via a displacement member (46).

摘要： A method for manufacturing liquid jet recording heads, each provided with discharge ports to discharge liquid, a discharge port plate having the discharge ports arranged therefor, and performing ablation processing of holes becoming the discharge ports by use of a mask for projecting the image of the mask onto the discharge port plate with coherent laser beam as light source, comprises the following steps of forming water-repellent layer on the surface of the discharge port plate on the liquid discharge side; and of performing the ablation processing by irradiating the laser beam from the reverse side of the surface of discharge port plate having the water-repellent layer formed thereon in a state of such surface being arranged to be under the atmosphere containing fluorine atom, and forming the discharge ports, at the same time, enabling the substance containing the fluorine atom excited by the laser beam to adhere to the surface having the water-repellent layer formed thereon. In this manner, the throughput of product manufacture is enhanced without any provision of extra processing steps to remove the byproducts to be created by the irradiation of laser beam, hence contributing to a significant cost reduction of the manufacture of liquid jet recording heads.
摘要翻译：一种液体喷射记录头的制造方法，每个液体喷射记录头均具有用于排出液体的排出口，具有排出口的排出口板，并且通过使用用于投影所述排出口的图像的掩模对成为排出口的孔进行消融处理将具有相干激光束作为光源的排出口板掩模，包括在排液侧的排出口板的表面上形成防水层的步骤; 并且通过在形成有所述防水层的排出口板的表面的背面照射激光束，在这样的表面被布置在含有氟原子的气氛的状态下进行烧蚀处理，并且形成排出口，同时使含有被激光束激发的氟原子的物质粘附到形成有防水层的表面上。以这种方式，增加了产品生产的吞吐量，而没有任何额外的处理步骤来除去由激光束照射产生的副产品，从而有助于大大降低液体喷射记录头的制造成本。

摘要： An electric actuator has a body with a hole defined therein and an electric motor fixed to an end of the body. The electric motor has a rotatable shaft to which a feed screw is coaxially connected, and a feed nut is threaded over the feed screw. The hole receives an elongate cylindrical tubular member slidably fitted therein which surrounds the feed screw. The feed nut is secured to an end of the tubular member, and a support for feeding a workpiece supported thereon is fixed to the other end of the tubular member. The feed screw, which serves as a drive force transmitting shaft, is protected by the surrounding tubular member from the deposition thereon of dust, dirt, or other foreign matter and hence from unwanted shutdown or breakage.
