    摘要： A winding section includes a primary winding to be excited by a single-phase A.C. signal, and a plurality of secondary windings provided at different locations with respect to a predetermined direction of linear movement. A variable magnetic coupling section includes a plurality of magnetic response members provided in repetition at a predetermined pitch along the direction of linear movement, and allows inductive A.C. output signals, amplitude-modulated in accordance with a varying linear position of an object of detection, to be produced in the individual secondary windings with amplitude function characteristics differing depending on positional differences between the secondary windings. Each of the inductive A.C. output signals produced in the secondary windings varies in its amplitude function in periodic cycles each corresponding to the pitch length of the magnetic response members. The variable magnetic coupling section may include a core section made of a wire, and the magnetic response members in the form of metal pieces provided at the predetermined pitch and secured by caulking to the core section.

    摘要： Two A.C. output signals amplitude-modulated in accordance with two function values (sine and cosine) differing from each other in correspondence to a position-to-be-detected are received from a position sensor such as a resolver. By performing an addition or subtraction between a signal derived by shifting the electric phase of one of the received A.C. output signals by a predetermined angle, and the other received signal, two electric A.C. signals (sin(.omega.t .+-.d.+-..theta.), sin(.omega.t.+-.d-.theta.)) are electrically synthesized which have electric phase angles (.theta.) corresponding to the position-to-be-detected and are phase-shifted in opposite directions. ".+-.d" here represents phase variation error caused by factors, other than the position-to-be-detected, such as temperature change. In the synthesized two signals, the phase variation errors (.+-.d) appear in the same direction, while the phase differences (.theta.) corresponding to the position are shifted in opposite, positive and negative, directions. Thus, by measuring the respective phase shift amounts (.+-.d.+-..theta., .+-.d-.theta.) and performing appropriate operation, it is allowed to cancel out or extract the error (.+-.d) so that an accurate phase difference (.theta.) can be detected.

    摘要： First absolute position detecting section generates an A.C. output signal having a phase electrically shifted in accordance with a position of a moving object, and samples a counted value of a counter circuit in response to an electrical phase change at a zero cross time point of the A.C. output signal, so as to output the sampled counted value of the counter circuit as absolute position data of the moving object. Second absolute position detecting section generates one or more delayed clock signals that are delayed from a clock signal on the basis of which the counter circuit counts up by an amount of time smaller than one period of the clock signal, and utilizes the one or more delayed clock signals to measure the zero cross time point of the A.C. output signal in accordance with a unit time smaller than the one period of the clock signal, so as to output, as the absolute position data, the measured time point after having been added to the sampled counted value.

    摘要： A position transducer has an input shaft coupled to a variable inductance sensor to produce an output electrical signal representing shift angle position. The transducer includes a plurality of rigid circuit boards which are hinged to one another so that the circuit boards and the electronic circuitry supported on the boards can be wrapped around the variable inductance sensor. The individual rigid circuit board segments are laminated onto a flexible sheet having conductive tracks. The track sheet provides the hinged effect.The power supply which is mounted on one or more of the boards provides DC power through an AC circuit fed by a transistor which is switched on and off as a function of the power needs of the transducer. By thus having an ON duty cycle substantially less than 100 percent, the heat generated in the power supply is minimized thereby making feasible the packing density afforded by the plurality of hinged circuit boards.

    摘要： This invention saves a sensed image in a printer in an environment in which a digital camera can directly communicate with a printer, and a sensed image can be directly printed.A printer (1000) and digital camera (DSC) can be directly connected to each other via a USB interface. Upon this direct connection, the digital camera and printer serve as a print system, and the DSC serves as a user interface in that system. When the user inputs a print instruction of a desired image on the DSC, a print process of that image is executed. When the user inputs a save instruction of a given image, that image is saved in a storage device in the printer. Even when the image is erased on the DSC side, original image data can be prevented from being lost.

    摘要： A first sensor detects a rotational position of a first shaft in a noncontact fashion and generates a first output signal by phase-shifting a reference A.C. signal in accordance with the detected rotational position of the first shaft. A second sensor detects a rotational position of a second shaft in a noncontact fashion and generates a second output signal by phase-shifting the reference A.C. signal in accordance with the detected rotational position of the second shaft. First and second timing signals corresponding to phase shift amounts of the first and second output signals are output via respective output lines. Relative rotational position detection data, representing a rotational difference or amount of torsion between the two shafts, appears in a time difference between the first and second timing signals. A PWM signal, having a pulse width corresponding to a time difference between the first and second timing signals, may be output.
