摘要： PROBLEM TO BE SOLVED: To apply pressure on an object with high accuracy via a piston rod driven by fluid pressure.
SOLUTION: A piston 15 is incorporated in a cylinder body 12 reciprocatingly and a piston rod 11 is supported to the piston 15 reciprocatingly. The leading end of the piston rod 11 projects outwardly from the cylinder body 12. The piston 15 and a diaphragm 33 for pressurizing define a pressurizing chamber 42, and the piston 15, the piston rod 11, a diaphragm 31 for balancing, and a diaphragm 32 for blocking define a balancing pressure chamber 34. The piston rod 11 is pressed in an advancing direction by supplying fluid pressure P3 to the chamber 42 in a state that thrust in a retreat direction is generated in the piston rod 11 by supplying fluid pressure P4 to the chamber 34, and gravity applied on the piston rod 11 is offset.

摘要： PROBLEM TO BE SOLVED: To accurately apply the pressurizing force to a material through a pressure rod to be driven by the pressure of a fluid.
SOLUTION: A reciprocating body 12 is assembled in a cylinder body 6, and the pressure rod 20 is reciprocatably installed in the reciprocating body 12. A tip of the pressure rod 20 is projected outward from the cylinder body 6. The reciprocating body 12 and diaphragms 17-19 divide inside the cylinder body 6 into a forward pressure chamber 27 and a dead-weight offset pressure chamber 29. After vertically setting the tip of the pressure rod 20 downward, the compressed fluid is supplied to the dead-weight offset pressure chamber 29 to offset the dead-weight of the reciprocating body 12 and the pressure rod 20. Thereafter, the compressed fluid is supplied to the forward pressure chamber 27 to push the pressure rod 20 through the fluid.

摘要： PROBLEM TO BE SOLVED: To provide a small fluid control valve whose valve opening is continuously changeable.
SOLUTION: In a valve casing 12, an orifice plate 21 is provided for partitioning a flow-in port 15 from a flow-out port 16. A valve chest 22 is formed in the valve casing 12 by the orifice plate 21. The orifice plate 21 has a plurality of communication holes 23, and the valve chest 22 stores a plurality of particles 24 each having a larger particle size than the communication hole 23. The orifice plate 21 is vibrated by a piezoelectric element 27 as a vibrator, whereby the particles are pulled away from the communication holes 23 to generate clearances between the communication hole 23 and the particle 24 and change the total communication area of the communication holes 23. Thus, the communication area between the flow-in port 15 and the flow-out port 16 is changed.

摘要： PROBLEM TO BE SOLVED: To easily form a durable scale on the surface of a movable member without making a fluid pressure drive apparatus large-scale, and eliminating damage to a packing seal due to irregularity of the scale.
SOLUTION: By irradiating a predetermined location of a piston rod 13 with laser beam, the irradiated part becomes high in temperature, and oxidation films 22 are formed by the part irradiated with the laser of the piston rod 13 being degenerated. Between the adjacent oxidation films 22, a non-machined part 25 which is in an untouched state without machining and having a different reflection ratio is formed on the piston rod 13. Thereby, man-hours for forming the scale can be reduced, and because durable oxidation films 22 become the scale, the scale does not easily peel off or rust. Further, the irregularities of the scale are minute so that damage to a rod packing is reduced, and the apparatus is avoided from becoming large-scale by forming the scale on the piston rod itself as a movable member.

摘要翻译：要解决的问题：为了在不使流体压力驱动装置大型化的情况下在可移动部件的表面上容易地形成耐用的刻度，并且消除由于标尺的不规则性而导致的密封件的损坏。解决方案：通过用激光束照射活塞杆13的预定位置，照射部分的温度变高，并且通过被退化的活塞杆13的激光照射的部分形成氧化膜22。在相邻的氧化膜22之间，在活塞杆13上形成未加工而具有不同反射率的未加工的未加工部25。因此，可以减少形成刻度尺的工时，因为耐用氧化膜22成为刻度，刻度不易剥落或生锈。此外，刻度的不规则性是微小的，从而减少对棒状填料的损伤，并且通过在活塞杆本身上形成作为可动构件的标尺，避免了装置变大。版权所有（C）2007，JPO＆INPIT
