摘要： A vehicle wheel bearing apparatus with a back-to-back double row tapered roller bearing has an outer member integrally with a body mounting flange and double row outer raceway surfaces tapered open respectively axially inward and outward. An inner member include a wheel hub and an inner ring or an outer joint member of a constant velocity universal joint. The wheel hub has a wheel mounting flange and one inner raceway surface arranged oppositely to one of the double row outer raceway surfaces and a cylindrical portion. The inner ring or the outer joint member of a constant velocity universal joint are press fit onto the cylindrical portion and include the other inner raceway surface arranged opposite to the other raceway surface of the double row outer raceway surfaces. Double row tapered rollers are freely rollably held between the outer and inner raceway surfaces by cages. Seals are arranged in annular openings formed by the outer and inner members. The cages are formed of synthetic resin. Posts between pockets of the cages are arranged to be positioned radially inward of the pitch circle diameter of the tapered rollers. The width of an opening radially inward of each pocket is set so that each tapered roller is held within the pocket. The contacting tapered surfaces of the posts open radially outward so that the rollers do not fall out radially inward.

摘要： The present invention provides a method for manufacturing a compound semiconductor, which can improve a quality of each of thin film layers constituting a laminate structure.Each of first and second thin film layers is formed by growing a crystal of each thin film layer one over another on a silicon substrate 2 in first and second vapor deposition chambers 6a and 6b for exclusive use, corresponding to the respective thin film layers. As this crystal growth is carried out under conditions under which nothing other than raw gas materials used therein or those derived therefrom, such as stuck materials, precipitates, etc., exists in the first and second vapor deposition chambers 6a and 6b, a decrease in quality of the second thin film layer can be prevented because an unexpected reaction between the raw gas materials used for the first and second thin film layers, etc. can be suppressed. Moreover, a conveyor space 35 extending between the first vapor deposition chamber 6a and the second vapor deposition chamber 6b, in which the silicon substrate 2 is conveyed, is disposed under an atmosphere of nitrogen gas or in a state of vacuum for suppressing oxidation of the thin film layer, thereby suppressing the oxidation of the first thin film layer constituting the outermost layer of the laminated thin film layers to form oxides.
摘要翻译：本发明提供一种化合物半导体的制造方法，其能够提高构成层叠结构的薄膜层的质量。第一和第二薄膜层中的每一个通过在对应于各个薄膜层的第一和第二蒸镀室6a和6b中的硅基板2上逐个生长每个薄膜层的晶体而形成。由于该晶体生长是在第一和第二蒸镀室6a，6b中存在的情况下，在其中使用的原料气体材料以外的其它原料或其衍生物，例如卡住材料，析出物等存在的条件下进行的，由于可以抑制用于第一和第二薄膜层等的原料气体材料之间的意想不到的反应，所以可以防止第二薄膜层的质量。此外，在第一蒸镀室6a和第二蒸镀室6b之间延伸有输送硅基板2的输送空间35配置在氮气氛下，也可以在真空状态下，抑制氧化从而抑制构成层叠薄膜层的最外层的第一薄膜层的氧化，形成氧化物。

摘要： Provided is a small-sized, lightweight, low-cost, and highly reliable bearing device for a driving wheel which needs no tapered spline, and eliminates a circumferential backlash in spline fitting portions to thereby prevent unusual noise. The bearing device for a driving wheel comprises an outer race (5) having an inner periphery in which double-row outer raceway surfaces (13, 14) are formed; a hub wheel (1) and an inner race (2) having outer peripheries in which double-row inner raceway surfaces (7, 8) opposed to the outer raceway surfaces (13, 14) are formed; and double-row rolling elements (3, 4) interposed between the outer raceway surfaces (13, 14) of the outer race (5) and the inner raceway surfaces (7, 8) of the hub wheel (1) and the inner race (2). A shaft hole (28) of the hub wheel (1) is formed into a cylindrical shape, and a male spline (26) is formed on an outer periphery of a stem section (27) of the outer joint member (15) so that the stem section (27) of the outer joint member (15) is press-fit into the shaft hole (28) of the hub wheel (1). With this, recesses caused to closely fit on the male spline (26) with interference are formed in the shaft hole (28) of the hub wheel (1), whereby the hub wheel (1) and the outer joint member (15) are separably coupled to each other.

摘要： In a voltage clamp circuit, a normally-on type field-effect transistor having a negative threshold voltage has a drain connected to an input node, a source connected to an output node and grounded via a resistance element, and a gate supplied with an output voltage of a variable direct-current power supply. When a voltage at the output node becomes higher than a clamping voltage because of voltage drop of the resistance element, the field-effect transistor is tuned off. Accordingly, the output voltage is limited to be at most the clamping voltage. Thus, a response speed is higher than those of conventional voltage clamp circuits using diodes or the like.
