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.
摘要翻译： 从诸如解析器的位置传感器接收根据与要检测的位置相对应的彼此不同的两个功能值（正弦和余弦）进行幅度调制的两个交流输出信号。 通过在通过将接收的AC输出信号之一的电相位移位预定角度而得到的信号与另一个接收信号之间执行加法或减法，则两个电AC信号（sin（ω+Δ+/- d +/- theta ），sin（ω-t +/-dθ））被电合成，其具有对应于要被检测的位置的电相角（θ）并且在相反方向上相移。 这里的“+/- d”表示除了要检测的位置之外的因素（如温度变化）引起的相位变化误差。 在合成的两个信号中，相位变化误差（+/- d）出现在相同的方向，而与位置对应的相位差（θ）在相反的正负方向上移动。 因此，通过测量各自的相移量（+/- d +/-θ，+/-dθ）并执行适当的操作，允许其抵消或提取误差（+/- d），使得准确 可以检测相位差（theta）。

摘要： An electronic flash control system and method for a high-speed repeating flash having a main capacitor which stores energy for flashing, a discharge element, a switching apparatus, a control unit and a photometric unit. The switching apparatus causes the discharge element to flash multiple times during the exposure operation of the camera based on a signal from the control unit generated in accordance with the duty ratio. The duty ratio for each flash is determined by the control unit based on a signal from the photometric unit representative of the quantity of light from the previous flash of the discharge element. As the control system does not perform real-time control, delays of the control system do not adversely affect accuracy.

摘要： An electronic flash apparatus is capable of discriminating the presence or absence of connection to a camera, and also the state of a connected camera. When the flash apparatus is connected to a camera capable of information transfer, the time required to transfer information is minimal. At least some of the terminals that connect the flash apparatus to the camera perform multiple functions. Different currents are supplied to certain terminals depending upon whether a connected camera is in an information transfer state or a flash photographing state. Terminal voltage detection controls certain functions, including varying certain terminal voltage.

摘要： A paper feeder of a label printer makes printing successively on a continuous printing paper on which a multiplicity of label papers are affixed. The paper feeder includes a control device for moving back the continuous printing paper by a length obtained by adding a fixed length capable of continuously making the next printing subsequently to a final printing position of the printing paper upon resumption of the printing operation when the movement of the printing paper is stopped by completion of the printing operation to an adjustment length for settling a printing position and makes printing successively from a fixed position of the label paper upon resumption after the printing operation is stopped. In this case, the adjustment length is set to a sum of a length from the printing start position of the printing paper upon resumption of the printing operation to a label position detection sensor disposed ahead in the backward direction and a length required to cause the printing paper to reach a constant speed upon resumption of the printing operation.
