Abstract: PURPOSE:To simplify the pattern constitution of interdigital electrodes, and to provide unidirectivity. CONSTITUTION:An interdigital transducer is constituted by forming the interdigital electrodes on the surface of a piezoelectric substrate. In a piezoelectric substrate 1, protruding portions 1a having inclined faces in the same direction are provided at prescribed intervals toward the propagating direction (shown by an arrow) of a surface acoustic wave, the electrode films of interdigital electrodes 2a and 2b are formed on the protruding portions by vapor deposition or hot etching, and the excitement of an exciting power source 3 is allowed to have directivity, so that the surface acoustic wave can be unidirectionally propagated. The pattern constitution of the interdigital electrodes is made equivalent to that of a general bidirectional transducer.

Abstract: PURPOSE:To obtain a highly accurate, simple, and inexpensive detector, by detecting which main detecting electrode faces a main electrode by phase discriminating circuits, and detecting the relative displacement quantity of a member. CONSTITUTION:When one member 7 is displaced in the direction of one end of the other member 1, a first main detecting electrode 12a faces a first main electrode in an overlapped manner, and remaining main detecting electrodes 12b, 12c... are deviated from the main electrode and do not face it. As a result, the electrostatic capacity of a first capacitor 16 in the first order becomes large. Then, the delay quantity of a pulse in a first delay circuit 15a in the first order becomes larger than the delay quantity of a pulse in a paired second delay circuit 17a in the first order. The phase of the pulse from the first delay circuit 15a lags from the phase of the pulse from the second delay circuit 17a. An output is sent to a counter circuit 21 from a first phase discriminating circuit 20a. Since the electrostatic capacity of the remaining first capacitors 16 remains small, outputs are not sent out of remaining phase discriminating circuits 20b, 20c....

Abstract: PROBLEM TO BE SOLVED: To eliminate the curl of a paper P curved along the circumferential surface of a heating roller at a thermal fixing time. SOLUTION: The ejecting angle θ1 of the paper P ejected from a fixing part A constituted of the heating roller 15 and a pressing roller 16 arranged in a fixing unit case is set to be smaller than the ejecting angle θ2 thereof at a paper ejection part B constituted of a paper ejection roller 17 and a pinch roller 18. Then, the ejecting speed of the paper P from the fixing part A is set to be higher than the ejecting speed thereof at the paper ejection part B by about 2%. Besides, the nip force of the paper P at the fixing part A is set to be stronger than the nip force thereof at the paper ejection part B. Thus, the curl is corrected by slackening the paper P so as to curving it in a reverse direction to the curving direction of the curl of the paper P ejected from the fixing part A between the fixing part A and the paper ejection part B.
