Filed: 1978-08-04
Abstract: PURPOSE: To save the beam splitter or the optical detector as well as to facilitate an easy control by applying the difference of the average value signals between the output of the voltage comparator to give a comparison between the modulated optical signal and the reference voltage and its inverse output to the optical modulator in the form of the bias.  
     CONSTITUTION: Output light 10 obtained by modulating input light 5 through optical modulator 3 and by the high frequency signal sent from input point 2 is supplied partially to output light detector 11 via beam splitter 9 and turned to modulated light intensity signal (i) to be then changed to binary voltage signal (e) according to the fact that is larger or smaller than the reference voltage (zero in this case) of voltage comparator 20. Signal (e) is then turned to averaged signals (g) and (h) through low-pass filters 23 and 24 along with binary signal (f) obtained by inverting signal (e). And the difference signal of signals (g) and (h) is supplied to modulator 3 via differential amplifier 14. Then the control is given so that the duty ratio may be 50% for output (e) and (f) and the output of amplifier 14 may be set to zero. As a result, the bias point drift caused the temperature change or the like can be prevented, and thus the bias point can be maintained at the optimum point of 1/2 the maximum output light.

Abstract: PROBLEM TO BE SOLVED: To provide a method for sensing adherence of microorganism membrane to a DO electrode capable of employing a suitable countermeasure such as cleaning by automatically detecting the adhered state of the membrane to the electrode used for a respiratory speedometer. SOLUTION: A respiratory speedometer by an active sludge process aerates active sludge liquid by introducing the air to the liquid, stops the deaeration after DO concentration is raised to a set value, degases it, measures the change of the concentration due to oxygen dissipation of aerobic microorganism of active sludge by using a DO electrode 20 and a DO meter, and calculates the respiratory speed of the sludge from the reducing speed of the DO by the method of least squares. In this case, the method for sensing the adherence comprises the steps of recording the change in the concentration by an automatic recorder, sensing the adherence of a microorganism membrane to the electrode 20 at the time of abrupt reduction in the DO at the degassing step, lifting the electrode 20, and conducting the countermeasure operation such as cleaning.

Title: Sheet feeder
Inventor: MATSUZAKA KOUJI
IPC: B65H7/18
Filed: 1981-06-18
Abstract: PURPOSE:To improve double feed detection accuracy and effectively utilize collected sheets, in a device used for an automtic money exchanger or the like, by expansibly curving the sheet when fed by a feed roller and detecting a double feed. CONSTITUTION:When a note 1 is fed by a feed roller 10, the note 1 is expansibly curved because its edge is stopped to a stopper 13. This expansible curve is detected by a sensor PH1 to decide the note if doubly fed or not by a control circuit, not shown in the drawing. At a double feed, the feed roller 10 is reversely rotated. This causes the note 1 to curve between the roller 10 and an upper plate 6, and separation retry is performed. Then the roller 10 is forwardly rotated to repeat refeed, curve and separation check operations. At confirmation of a single feed, the roller 10 is stopped, and the stopper 13 overturns, then the note 1 is held with the edge between pick off belts 18, 19 by its restoring force. Then the roller 10 is again driven to feed the note.

Abstract: PURPOSE:To increase the rotational life of the rotor, and improve the quality and the reliability of a rotary-anode X-ray tube by providing bearings between the rotor and a supporting shaft, which supports the rotation of the rotor and to which an umbrella-type target plate is connected, and making the length in the axial direction of the inner rings of the bearings connected to the shaft larger than the length in the axial direction of the outer rings of the bearings connected to the rotor. CONSTITUTION:Two bearings 11 and 12 are provided between the ends of a supporting shaft 1 and a cylindrical rotor 3. The length (l1) of inner rings 11a and 12a of the bearings 11 and 12 connected to the supporting shaft 1 is larger than the length (l2) of outer rings 11b and 12b of the bearings 11 and 12 connected to the rotor 3 by above 20%. Owing to the above constitution, when the bearings 11 and 12 provided at both ends of the shaft 1 are pressed by the spring force of a spring 6, the bearings 11 and 12 are hardly slanted since the inner rings 11a and 12a having the length (l1) larger than the length (l2) of the outer rings 11b and 12b are connected to the shaft 1. As a result, the bearings 11 and 12 rotate smoothly, any trouble of the defective rotation of the rotor 3 is prevented, and the rotational life of the rotor 3 is lengthened.

Filed: 1988-04-19
Abstract: PURPOSE:To reduce the influence of a synchronizing signal to a video signal and to prevent the degradation in picture quality, etc., from being generated by causing the synchronizing signal, which is transmitted from a camera control unit to a camera head unit, to be the amplitude modulating signal of a high frequency signal. CONSTITUTION:For the synchronizing signal to be transmitted from a camera control unit 1, the high frequency signal is amplitude-modulated (circuit 11) by the synchronizing signal to be generated in the camera control unit 1. Then, an amplitude modulating signal is demodulated (circuit 14) by a camera head unit 2 and the synchronizing signal is obtained. Thus, by causing the transmitted synchronizing signal to be the amplitude modulating signal of the high frequency signal, the influence of the synchronizing signal is reduced to the video signal and the degradation of the picture quality, etc., due to the influence can be widely improved.

Abstract: PURPOSE: To enhance the efficiency of oil exchange and to prevent the mixing of bubbles by providing a sweepback angle to the front edge of the pad, which is divided into sector-shaped ones and arranged in the circumference of bearing, in the radial direction.  
     CONSTITUTION: When a sweepback angle α is provided to the front edge of the pad 1a in the radial direction, the gap 3a forms a passage that retreats outwards with respect to the rotary direction. By this way, oil with a turning velocity U given by the rotation of rotary disc is forcibly provided a velocity component Usinα along the angle α when the oil is checked by the front edge. As a result, since the oil in the gap flows on forming a strong outward turning flow, the efficiency of oil  exchange is improved and bubbles are prevented to enter the spacing between  the moving faces.
