摘要： In a spindle apparatus for a machine tool, a spindle is supported on a housing by support-purpose bearing devices, and is rotated by an electric motor, and a tool is attached to a tool attaching portion formed at a distal end of the spindle. A radial magnetic bearing for vibration suppressing purposes which includes a plurality of electromagnets is provided around the tool attaching portion of the spindle. A plurality of radial displacement sensors for detecting a displacement of the tool attaching portion in radial directions are provided around the tool attaching portion. There is provided an electromagnet control unit for controlling the electromagnets of the radial magnetic bearing on the basis of outputs of the radial displacement sensors so as to support the tool attaching portion in a predetermined position.

摘要： A grinding wheel having a convex grinding surface is attached to a wheel spindle that is contactlessly supported by a casing through a controlled type axial magnetic bearing and controlled type radial magnetic bearings and that is rotated by an electric motor. A groove of a workpiece is ground by causing relative displacement of the casing. After the axial positioning of the casing is performed, the casing is radially displaced. Then, the groove is ground. The stiffness value of the axial magnetic bearing 6 is set to be lower than a normal value before the casing is radially displaced. After it is detected that the grinding surface of the grinding wheel touches the entire groove of the workpiece and that the grinding of the entire surface of the workpiece is started, the stiffness value is set back to the normal value.

摘要： System(s) and method(s) to probe electromagnetic fields at the surface of a solid-state material are provided. The technique combines ultrafast (e.g., less than 10 fs) optical excitation and electron microscopy to generate electronic excitations and image the ensuing electromagnetic fields with nanometer-scale spatial resolution and femtosecond time-scale resolution. In addition, time-of-flight energy analysis facilitates imaging of relaxation a generated electronic excitation. The dynamics of the electromagnetic fields can be probed interferometrically through generation of multi-frame imaging, with inter-frame frequency of the order of a few hundreds of attoseconds, of interference patterns among an electric field associated with an excitation in a sample or device and the electromagnetic field of a probe pulse coherent with an excitation pulse. Quality assurance of nanoscopic devices based on plasmonic, photonic, electronic, spintronic operation can be analyzed with spectroscopy provided in the subject innovation.

摘要： An electrophotographic toner is formed as a blend of toner particles and external additives. The external additives include (1) first inorganic fine particles having an average primary particle size of 80-800 nm of oxide of a metal selected from the group consisting of titanium, aluminum, zinc and zirconium, (2) second inorganic fine particles other than silica having an average primary particle size of below 80 nm and (3) silica fine particles having an average primary particle size of below 30 nm. As a result, the toner can be made free from difficulties, such as melt-sticking onto an image-bearing member in a low humidity environment, roughening of halftone images in a low humidity environment, toner blot-down after storage at high temperatures or in continuous image formation on a large number of sheets, fog in continuous formations of images of low color area percentage in a low humidity environment, and re-transfer in multi-color image formation. Thus, the toner is suitably used in a multi-color image forming system.

摘要翻译：作为调色剂颗粒和外部添加剂的混合物形成电子照相调色剂。外部添加剂包括（1）选自钛，铝，锌和锆的金属的氧化物的平均一次粒径为80-800nm的第一无机细颗粒，（2）除了钛，铝，锌和锆之外的第二无机细颗粒平均一次粒径小于80nm的二氧化硅和（3）平均一次粒径小于30nm的二氧化硅微粒。结果，可以使调色剂无困难，例如在低湿度环境下熔融粘附到图像承载部件上，在低湿度环境下使半色调图像粗糙化，在高温下储存后的调色剂印迹下降;或在大量纸张的连续成像中，在低湿度环境下连续形成低颜色面积百分比的图像，并且在多色图像形成中重新转印。因此，调色剂适用于多色成像系统。

摘要： A process for producing a toner. The process has the steps of dispersing a fine-particle colorant in a liquid monomer mixture containing at least a liquid polymerizable monomer, dispersing the resulting colorant-dispersed liquid monomer mixture in an aqueous dispersion medium to form particles of a polymerizable monomer composition, and polymerizing polymerizable monomers present in the particles in the aqueous dispersion medium to form toner particles. In the dispersion step, a media particle agitation type wet-dispersion machine is used as a dispersion means. The dispersion machine has a cylindrical vessel having a first wall surface having a liquid-feed opening and a second wall surface having a liquid-discharge opening. The vessel is inside provided with an inner chamber and an outer chamber which are partitioned with a cylindrical separator having slits, a rotor set in the inner chamber rotatably by the rotary drive motion of a drive shaft, and a plurality of spherical media particles held in the inner chamber.
