A telescopic cover apparatus, which is mounted on a machine tool, includes a telescopic cover, including first to seventh cover members slidably fitted with one another, and a pantogragh drive mechanism including first to sixth parallelogrammatic link mechanisms continuously arranged in the cover extension/contraction direction. Each link mechanism includes first to fourth link members and first to fourth joints for pivotally coupling the link ends to one another. When a movable table of the machine tool moves, the first cover member fixed to a stationary saddle of the machine tool, along with the first joint of the first link mechanism, is kept at a standstill, while the seventh cover member fixed to the movable table, along with the fourth joint of the sixth link mechanism, moves in unison with the table, and the second to sixth cover members, connected to the respective fourth joints of the first to fifth link mechanisms aligned with one another, smoothly and cooperatively move in unison with these joints along guide rails.

An automatic tool exchanging device for a machine tool, comprising a stopper block (5, 5') attached to a magazine supporting member (2) supporting a magazine (1) at the lower end thereof and capable of swinging to the front and rear, and pulled by an elastic member (8) having one end connected to the upper end of the magazine supporting member (2). Upon arrival of the magazine (1) at a standby position from a tool exchanging position, a stopper (4, 4', 11) is engaged with the stopper block (5, 5') to prevent vibration of the magazine (1). A desired tool among various tools stored in the turret magazine is selected automatically and automatically exchanged for a tool on the machine tool.

An illumination controlling device for a vehicle includes a controlling portion to change a luminance phase of a meter based on operation of an operating portion and to maintain a luminance phase of a lighting while the lighting is extinguished. The controlling portion changes the luminance phase of the meter based on the operation of the operating portion and changes the luminance phase of the lighting to correspond to the luminance phase of the meter if the operating portion is operated in a state that the luminance phase is different between the meter and the lighting while the lighting is illuminated.

This invention relates to: a method for differentiating osteoclast precursor cells (preosteoclasts) into osteoclasts, which comprises culturing the preosteoclasts in the absence of accessory cells; a method for isolating preosteoclasts, which comprises culturing peripheral blood or joint fluid in the absence of cytokine for 1 to 3 weeks; an preosteoclasts, which is obtainable by the above method; a method for differentiating the preosteoclasts obtained by the above method into osteoclasts, which comprises culturing the preosteoclasts in the absence of accessory cell; an osteoclast, which is obtainable by the above method; a method for screening agents for treating metabolic bone diseases, which comprises using the preosteoclasts or the osteoclasts as described above; and agents for treating metabolic bone diseases, which is obtainable by the above screening method.
摘要:
In a motor or an electromagnetic driving device having a first stator yoke excitable by energizing a first coil, a second stator yoke excitable by energizing a second coil and a rotor opposed to the first and second stator yokes to be driven and rotated by energizing the first and second coils, the first and second coils are collectively arranged together in one direction on the outer side of the periphery of the rotor, and the first stator yoke is arranged in a state of being superposed on the second stator yoke to form an electromagnetic driving motor. The electromagnetic driving motor is thus arranged in a novel shape to be capable of preventing a noise of driving transmission while maintaining its adequate performance as an electromagnetic driving motor and to be compactly mountable on a camera or the like for its diaphragm device without any protruding part.

A motor includes a first stator yoke which is excitable by energization into a first coil, a second stator yoke which is excitable by energization into a second coil, and a rotor which can be driven for rotation under the control of energization into the first coil and the second coil, wherein the first stator yoke and the second stator yoke are disposed in the rotational axial direction of the rotor, while the rotor is provided with a rotational output portion which can take out the rotational output with a gap between the first stator yoke and the second stator yoke. By this arrangement, a novel motor can be configured to take out the rotational output without problems of noise generation in the motor transmission drive, fully coping with the mounting conditions on the products.
