Abstract: An information processing apparatus includes an acquisition unit configured to acquire a first phase signal and a second phase signal that are acquired by measuring a rotation of a moving object, and a calculation unit configured to calculate a rotational angle by an iterative calculation so as to satisfy a relational expression bearing an arctangent. The relational expression bearing the arctangent uses a first cosine wave and a second cosine wave at a higher harmonic of the first cosine wave for the first phase signal, and a first sine wave and a second sine wave at a higher harmonic of the first sine wave for the second phase signal. The first phase signal and the second phase signal may, for example, be analog signals having a wave shape.

Abstract: A feed assembly for transferring an uncoiled sheet material to a downstream material forming operation. The assembly includes upper and lower feed rolls between which the sheet material passes, the upper roll being actuated between engaging or disengaging positions relative to an upper surface of the sheet material. At least one continuous force applying component is provided for exerting a hold down force against the upper feed roll and, in combination, a programmable counterbalance component is calibrated to counter the hold down force exerted by the force applying component and in order to cycle the upper roller between the engaged and disengaged positions during advance cycling of the uncoiled material to the downstream forming operation.

Abstract: An apparatus for feeding pasta sheet into a pasta-making machine, includes a feed device for feeding a strip of pasta sheet along a predetermined path, and a punching device designed to operate on the strip in the stop condition so as to punch the strip and obtain from the strip cut pieces of pasta sheet intended to be wrapped around respective portions of filling, thereby producing respective pieces of filled pasta. The apparatus includes a speed variator device for the feed speed of the strip, interposed between the feed device and the punching device for causing, during each machine cycle of the apparatus, a variation in the speed of a branch of the strip positioned at the punching device which, in combination with the speed at which the strip is supplied by the feed device, stops the branch of the strip.

Abstract: A transportation path changing device (1) of the invention is a transportation path changing device that changes a transportation path of a continuous sheet-like object (3) that is being transported. The device includes: an oscillating section (2) that oscillates in an intersecting direction Y intersecting with a flow direction X of the transported object, and that increases/decreases the length of the transportation path of the transported object (3); a first moving means (6) that is connected to the oscillating section (2), and that moves the oscillating section (2) in the intersecting direction Y; a second moving means (7) that moves a portion or the entirety of the first moving means (6) in the intersecting direction Y; and a control section (9) that controls the first moving means (6) and the second moving means (7).

Abstract: A feeding device includes a fixing base. A motor is fixed to the fixing base. The motor has an output axle. A transmission axle is fixedly connected to the output axle. The feeding device further includes a feeding block having a side fixedly connected to the transmission axle. The feeding block has a feeding notch. The feeding notch is formed around the transmission axle circumferentially. Hence, once a slender material enters the rotational space of the feeding block, the motor drives the feeding block to rotate, whereas the slender material is pressed by the feeding notch of the feeding block and sent out as a result of the continuous rotation of the feeding block. Hence, the feeding device not only enables continuous material conveyance but also allows the slender material to be conveyed smoothly even when the slender material is slightly bent or deformed.

Abstract: Two intermittently and oscillating driven feeding rollers (2; 3) are adapted to feed a strip-shaped workpiece (63). The bottom feeding roller (2) is supported in the frame (1) of the feeding device. The upper feeding roller (3) is supported in a rocker (30). The movement of the rocker (30) is controlled by a control disk (64) through a lever and a rod arrangement (40). The rocker (30) rests at one end (33) via a pressure spring (39) against the frame (1). At the opposite end (34) the rocker (30) rest against the frame (1) via a further pressure spring (36). The rocker (30) is supported in an overhung state on a cantilever which consists of a sleeve (70), a arm (71) projecting laterally from the sleeve (70) and a shaft (72) held clamped in the arm (71). The clamping bar (46) is firmly mounted to the shaft (72).

Abstract: The invention provides an electric wire feeding apparatus which can be easily changed at a low cost and without a great design change from the roll feeding type apparatus to the belt feeding type apparatus. In an electric wire feeding apparatus having an electric wire base table (21), a pair of rotary shafts (25, 26) arranged in both sides of an electric wire (W) of the electric wire base table (21), and rotating bodies (47) fixed to the respective rotary shafts (25, 26) via attaching and detaching means (27), there are provided a pair of belt feeding units (C), each having a belt feeding table (45), a driven pulley (46) rotatably supported to the belt feeding table (45), a drive pulley (47) having a rotational position restricted by the belt feeding table (45), and a belt (48) wound between the drive pulley (47) and the driven pulley (46).

Abstract: Apparatus and method for manufacturing helically wound insulated conductors with filament fillers includes first and second payoff stations for paying off a plurality of insulated conductors and elongate filaments of filler materials. These cable components are guided from the payoff stations to a closing die, and are arranged in positions suitable for twisting into a cable by a double twist machine to form a cable of twisted insulated components forming radially outwardly facing helical interstices each of which is substantially filled with another one of the filaments of filler material. Differential or incremental lengths of filler material are metered upstream of the double twist machine to compensate for the differences in the radial distances of the insulated conductors and filaments of filler material on the center or cable of the axis.
