Abstract: PURPOSE:To realize a transducer having high stability and high accuracy, by executing addition and subtraction of each DC voltage being proportional to a power of a phase difference of 2 AC inputs, and reference voltage, so that DC voltage being proportional to a power-factor can be outputted. CONSTITUTION:Each AC input of a phase difference (phi) of a terminal 1 and 2 becomes sqaure wave voltage by a comparator 11 and 12, exclusive OR is taken by a gate 13, and it becomes voltage 53 of a duty ratio being proportional to the phase difference (phi). The voltage 53 is applied to a control terminal of switches S1, S2, and S1 outputs a peak value Ez by making reference voltage Ez pass through when the voltage 53 is high, and by making it pass through a filter A1, DC voltage E21 being proportional to the phase difference (phi) is obtained. The voltage E21 is supplied to S2 and A2, and in the same way, as to the phase difference (phi), voltage E22 being proportional to phi<2> is obtained. Voltage E21, E22 and Ez is subjected to addition and subtraction in the decided ratio by an adding and subtracting circuit AD, and DC voltage E25 being proportional to a power-factor of an input is outputted.

Title: Engine control device
Inventor: YOKOTA KAZUYA
IPC: F02D45/00
Filed: 1989-06-15
Abstract: PURPOSE:To prevent the generation of knocking and the like due to abnormal combustion at the time of open-loop control by controlling the other engine output controlled variable in the direction of suppressing combustion when the learning value of the air-fuel ratio feedback correction value is cleared. CONSTITUTION:An engine control unit 27 inputs the signal of engine rotation, water temperature, air flow, air fuel ratio, throttle opening, and the like detected at sensors 9, 20, 26, 28, and feedback-controls the air-fuel ratio using the learning value obtained by operating the air-fuel ratio of mixture on the basis of the feedback correction value. When the learning value in a memory 29 to be used for the control of the air-fuel ratio is cleared for some reason, the control unit 27 controls the other engine output controlled variable, for instance, the ignition timing in the direction of suppressing combustion. The generation of knocking due to abnormal combustion is thus prevented especially at the time of open-loop control when the feedback control of the air-fuel ratio is stopped, thereby improving the reliability of the engine.

Title: Magnetic burglerproof card
Inventor: YUUGO RIIBUENSU
IPC: G08B13/24
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To manufacture a magnetic robbery preventing card having a soft magnetic film as an electronic article inspection (E. A. S.) system active element. SOLUTION: The soft magnetic thin film 100 has an easy shaft 102 (or a magnetic priority orientated shaft) in a specified direction. Since the card is folded along at least one folding line 104, the card has at least two layers which are partially overlapped. Since the folding line 104 crosses with the direction of the easy shaft 102 and the angle of skew is formed, the direction of the easy shaft 102 in one layer differs from the direction of the easy shaft 106 of the other layer. Thus, the robbery preventing card which is not affected by self orientation or direction at the search exit of the E. A. S. system can be obtained.
