摘要： A plurality of different reference voltages are generated. A set of differential conversion circuits has first input terminals subjected in common to an analog input signal and second input terminals subjected to the respective reference voltages, and converts differences between voltages at the first and second input terminals into differential output voltages. A first A/D conversion circuit compares the analog input signal with the reference voltages to perform a higher-order A/D conversion of the input analog signal. At least two of the differential output voltages are selected. An interval between the selected differential output voltages is divided, and divided voltages are generated in accordance with the division. A second A/D conversion circuit compares the divided voltages to perform a lower-order A/D conversion of the analog input signal.

摘要： A serial-type analog-to-digital converter includes a plurality of serially connected folding circuits. Each folding circuit includes a first operational amplifier having an inverting input connected to an input terminal, and a second operational amplifier having a noninverting input connected to the input terminal. The bases of first and second transistors are respectively connected to the outputs of the first and second operational amplifiers. The emitters of the transistors are commonly connected to an output terminal. Feedback connections are provided for coupling the output terminal to the inverting input of each operational amplifier. Furthermore, circuitry is provided for calculating an estimated offset error based on maximum values of a folded analog signal provided at an output terminal of one of the folding circuits.

摘要： A tool changer has a rotatably supported driving shaft, a cylindrical double-walled support member composed of an inner cylindrical wall and an outer cylindrical wall, disposed coaxially with the driving shaft, and engaged therewith through helical splines, a cylindrical guide member having a cylindrical portion interposed between the inner cylindrical wall and outer cylindrical wall, a plurality of claw members fixed to the outer cylindrical wall for retaining tools, and a servomotor for rotating the driving shaft clockwise and counterclockwise. In an outer periphery of the cylindrical portion of the guide member are formed a plurality of axially extending straight grooves, each having an inclined side surface at respective tip ends, which extends in one direction, and an engaging member biassed by a spring member projects into one of the straight grooves so as to be engaged therewith. The clockwise rotation of the driving shaft causes the support member to move forwardly in an axial direction while the engaging member is engaged with one of the straight grooves of the guide member. At an end of the forward movement of the support member, the engaging member leaves the straight groove after passing the inclined side surface so as to rotate the support member by a predetermined angular distance and to bring the engaging member into engagement with another one of the straight grooves. The succeeding counterclockwise rotation of the driving shaft causes the support member to move backwardly.
摘要翻译：工具更换器具有可旋转地支撑的驱动轴，与内圆柱形壁和外圆柱形壁构成的圆柱形双壁支撑件，与驱动轴同轴设置，并通过螺旋花键与其接合;圆柱形导向件，插入在内圆筒壁和外圆筒壁之间的部分，固定到用于保持工具的外圆筒壁上的多个爪构件，以及用于顺时针和逆时针转动驱动轴的伺服电机。在引导构件的圆筒部的外周形成有多个轴向延伸的直槽，每个具有在一个方向上延伸的相应末端的倾斜侧表面，并且由弹簧构件偏压的接合构件突出到直槽之一与其接合。驱动轴的顺时针旋转使得支撑构件在轴向方向上向前移动，同时接合构件与引导构件的一个直槽接合。在支撑构件向前运动的结束时，接合构件在通过倾斜侧表面之后离开直槽，以使支撑构件旋转预定的角距离，并使接合构件与另一个直槽驱动轴的后续逆时针旋转使得支撑构件向后移动。
