摘要： PROBLEM TO BE SOLVED: To provide a jitter measuring device capable of eliminating unnecessary detection signals and measuring variance of scanning time in an image forming apparatus of a galvano scanner system. SOLUTION: This is the jitter measuring device of a galvano scanner that scans a light beam on a surface (23) to be scanned by periodically rotatably reciprocating a reflection mirror 10. The device is equipped with two detectors A, B that are installed near both ends of a light beam scanning region to receive and detect light beams, two extracting means 1 that extract the first detection signal of the detectors A, B each time the reflection mirror 10 starts to operate for one scanning, and a means 2 for computing the required time on one scanning from the detection signals extracted by the two extracting means 1. On the basis of the required time so computed, measurement is done for the variance of the required time on each scanning, in the structure of the device. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To solve the problem that the conventional flow meter is not desirable for reasons of sanitation and has economical futility, and lifetime is short.
SOLUTION: The usage sensing device of a filter for liquid treatment converts the pressure of liquid flowing in a filter 2 into a capacitance by using a diaphragm type pressure sensor 4, converts the capacitance into a frequency, and measures flow rate from the frequency. The sensing device is provided with a diaphragm, a movable electrode plate and a fixed electrode plate, and constituted of a pressure sensor for converting the pressure of flowing liquid into the capacitance, a frequency converter for converting the capacitance into the frequency and a treater for measuring the flow rate of liquid from the frequency. The pressure sensor is so fixed that the diaphragm faces the inside of a through conduit.

摘要： PROBLEM TO BE SOLVED: To solve the problem of the low reliability of measurement due to the change of read data caused by speed unevenness for conveying the magnetic card of a reader. SOLUTION: When the recorded data of a magnetic card is read, the speed unevenness of the card conveying system if a reader is measured, and the speed unevenness is subtracted from the measured value of a magnetic flux inversion interval read by the reader and displayed. The absolute values of the measured magnetic flux inversion interval and magnetic field intensity are displayed. '0' and '1' are separately displayed. The movement average of both of the magnetic flux inversion interval and the magnetic field intensity is displayed. Measurement is carried out by a plurality of times, and the magnetic field intensity and the magnetic flux inversion interval are averaged for each recording position and displayed. An appropriateness determination area is displayed in the abscissa and the ordinate of a screen. Measurement data is superposed on the recorded data of a reference card to be displayed. A difference between the measurement data and the reference card.

摘要： PROBLEM TO BE SOLVED: To reduce noises and vibrations generated by interference of the meshing surface of a gear installed in a revolving device by absorbing a backlash of gear, error in machining, and an installation error. SOLUTION: A swinging member 10 consisting of an intermediate gear mounting lever 10a and a motor mounting lever 10b is swingably supported on a turntable 7, and a pulse motor 14 is fixed to the lever 10b, and an intermediate gear 11 meshing with a drive gear 15 mounted on the pulse motor 14 is pivoted on the lever 10a and is meshed with an inner gear 6a formed on a stationary ring 6. The free end of the lever 10b is pressed by a tension spring 17 toward the inner gear 6a. The meshing surfaces of gears 15, 11, 6a are pressed and contacted by the tension spring 17 so that backlash, etc., is absorbed.
