Abstract: An A/D converter includes an adder that calculates a difference between an analog input signal and a predicted value, a quantizer that quantizes the difference output from the adder to convert the analog input signal to a digital signal, a prediction filter that generates a predicted value from the digital signal output from the quantizer, and a D/A converter that converts the predicted value from a digital signal to an analog signal and output the predicted value to the adder. The predicted value before being subjected to conversion to the analog signal by the D/A converter defines and functions as an A/D converted output of the analog input signal input to the adder.

Abstract: A current sensor for outputting a detection signal corresponding to a current flowing through a bus bar. The current sensor includes a magnetic core that concentrates and amplifies magnetic flux generated by the current near a detection portion of the bus bar. A magnetic detection element detects the magnetic flux concentrated by the magnetic core and outputs an electrical signal corresponding to the detected magnetic flux. A signal processing circuit includes electronic components and processes the electrical signal output from the magnetic detection element to generate the detection signal. A lead frame holds the magnetic detection element and the electronic components. The magnetic detection element, electronic components, and lead frame are combined to form a single sensor module. The current sensor detects the current flowing through the bus bar with the sensor module and outputs the detection signal.

Abstract: A drive shaft is configured from a shaft body, a shaft portion provided with extensions and boot mounting parts coaxially and integrally formed on ends thereof, and constant velocity joints attached to ends of the extensions via interior members. The outer diameter of intermediate portions of the extensions is smaller than that of the ends and the boot mounting parts. Formed on the opening-sides of the inner surfaces of the exterior members of the constant velocity joints are flanks that face outward and leave a slight clearance with the intermediate portions. Edges forming the boot mounting part sides of the intermediate portions are set to positions corresponding to outer edges of the flanks, and tapered portions connect the edges and the boot mounting parts.

Abstract: According to a film removing device, a film-coated resin molded material having a film coated on one surface of a matrix resin is flattened by a flattening roll in a heating chamber. Further, the film-coated resin molded material is fed between a peeling roll and a feeding roll of roll type rolling means for rolling and stretching. The velocity of a peeling surface of the peeling roll is made relatively higher than the velocity of a feeding surface of the feeding roll, whereby a difference in elongation between the matrix resin and the film, and a shearing force are produced to peel the film. An applicator type supply device supplies a liquid as frictional force reducing means (e.g. water) to the peeling surface and the feeding surface. Thus, a frictional force is reduced, and stretching accompanying rolling fully works. Consequently, the film becomes easy to fracture and peel, and its peeling can be performed effectively.
