摘要： PROBLEM TO BE SOLVED: To provide a movable mechanism such as a machinery mechanism with an inexpensive waterproof and dustproof structure having a simple configuration.
SOLUTION: In this waterproof and dustproof structure, a liquid accumulation section 13 sandwiched by an inner side rising wall part 11 and an outer side rising wall part 12 of a stationary member 10 is provided in a part equivalent to an inlet of a clearance 30 between the stationary member 10 and a movement member 20. The movement member 20 performs movement while its tip part 21 is immersed in liquid LQ. The liquid LQ shields a region on an inner side of the device for a region on an outer side of the device to prevent intrusion of foreign matter such as mist and dust. Even if the clearance 30 is made comparatively wide, foreign matter intrusion preventing action is achieved. The direction of movement of the movement member 20 includes vertical, left and right, forward and backward, rotation directions or synthesis of them in accordance with type of the movable mechanism to which the waterproof and dustproof structure is applied. Working fluid used in a fluid bearing and working fluid used in a machine tool can be diverted to the liquid LQ.

摘要： PROBLEM TO BE SOLVED: To improve a motion control characteristic such as suppressing vibrations of a moving member by using the liquid in improving a water-proof and dust-proof structure realized by liquid in a liquid pool which blocks off internal and external portions of a device.
SOLUTION: A clearance 30 is formed between a static member 10 and a moving member 20. A liquid pool 13 is provided in a potion corresponding to an entrance of the clearance 30. A high-viscosity liquid LQ is held in the liquid pool 13. An apical end 21 of the moving member 20 moves with itself immersed in the liquid LQ. The liquid LQ blocks off the internal and external portions of the device, enabling foreign matters to be prevented from entering therein. Due to the high viscosity of the liquid LQ, vibrations generated in stopping a motion of the moving member 20 can be suppressed. Further, a damping operation becomes better to improve the motion control characteristic of the moving member. Furthermore, by changing the viscosity of the liquid LQ by applying a voltage thereto, low-viscosity is realized in the motion of the moving member and when stopping the moving member, high-viscosity is realized. As a result, the motion control characteristic of the moving member can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a machining device which easily and efficiently carries out machining of a minute predetermined pattern such as in dimple machining for a light guide plate. SOLUTION: According to the operation of the machining device, a movable section 2 is linearly moved by a linear driving means 1. The movable section 2 has a sensor 6 arranged thereon, for scanning a light and shade pattern of a light and shade pattern member 3, and the sensor 6 generates an output signal having a different magnitude according to the gradation of light and shade of the light and shade pattern. According to the magnitude of the output signal from the sensor 6, a cutting means 7 controls a cutting stroke of a tool 5, and carries out machining of a workpiece 4. The workpiece 4 is machined according to the light and shade pattern. Thus, without creating a machining program, the movable section 2 is positioned, and while the movable section 2 is moved at a constant speed without stopping, the machining is carried out according to the light and shade pattern. Machining of the minute predetermined pattern such as a mold of the light guide plate having a number of dimples is thereby easily and efficiently carried out. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a braking device which allows for a low cost and needs a small space in moving members such as a rotary shaft using a fluid dynamic bearing, and a direct operated slide.
SOLUTION: The rotary shaft (moving member) 1 which is supported by the fluid dynamic bearing is borne by a bearing member 2. Upper and lower thrust bearing surfaces and radial bearing circumferential surfaces are formed such as to surround the outer circumferential end portion of a disc 1a which is provided to the rotary shaft 1. A pressurized fluid is supplied on each bearing surface through the fluid path 3a to 3c via a nozzle 4 to form a fluid bearing surface. When rotating the rotary shaft 1, the pressurized fluid is supplied into all the fluid paths 3a to 3b to keep the rotary shaft 1 and the disc 1a from contact with the bearing member 2 as shown in Figure (a). When applying a brake, a supply of the fluid into the path 3b is blocked off as shown in Figure (b). The rotary shaft 1 is caused to come down by the pressure that is applied on the bearing surface on the side of the path 3a, causing a braking member 1b to come into contact with stationary section 5 to effect braking. Thus, a special braking device is not required.

摘要： PROBLEM TO BE SOLVED: To provide a spindle capable of suppressing the generation of heat and vibration in a center-through coolant system.
SOLUTION: A coolant supply member 5 having a nozzle 5a is fixed to a housing 2 of the spindle 1. A rotating hollow shaft 3 supported to the housing 2 by a fluid bearing 9 is formed with a tapered hole 7 large in diameter on the mounting side of a tool 4. The nozzle 5a is inserted in a non-contact state into the tapered hole 7 of the hollow shaft 3 and fixed. A coolant supplied into the rotating hollow shaft 3 from the nozzle 5a advances to the diameter enlarged tool side by centrifugal force caused by rotation, and is discharged into the vicinity of a workpiece machining point of the tool 4 through a discharge hole 8. Since the coolant can be supplied in a non-contact state into the rotating hollow shaft 3 and discharged into the vicinity of the machining point, heat generation and vibration of the spindle can be suppressed.

摘要： PROBLEM TO BE SOLVED: To obtain a drive coil in which a fluid bearing can be realized, and a linear driver simple to guided requiring no special cooling means.
SOLUTION: The drive coil 30 is manufactured by making a spiral groove on the surface of an insulator, pouring molten conductor into the groove and solidifying the conductor. The drive coil 30 has a smooth surface which can serve as a fluid bearing face. The drive coil 30 is fixed to a base 1 and a magnet 4 fixed to a mover 2 is disposed oppositely to the drive coil 30 through a magnetic gap. The magnet 4 also has a smooth surface which serves, along with the face of the drive coil 30, as an air bearing 7. The mover 2 is moved in the direction perpendicular to this paper plane when the drive coil 30 is excited. Since only the air bearing 7 is required in the vertical direction, guide means of the mover 2 is simplified. Furthermore, no special cooling means is required because the coil is cooled directly by the compressed air of the air bearing.
