Title: Measuring apparatus for flow velocity
IPC: G01P5/22
Filed: 1992-03-24
Abstract: PURPOSE:To easily and correctly measure the absolute value of the flow velocity irrespective of the concentration of a fluid in a flow velocity measuring apparatus which forms an image of particles in the fluid onto a detecting aperture of a predetermined size and measures the flow velocity of the fluid from several fluctuations of the image of particles passing the aperture. CONSTITUTION:Two laser lights of different wavelengths projected from laser light sources 18, 19 illuminate, as an illuminating light, the ocular fundus Er of a to-be-inspected eye E via an optical system comprised of a lens 21 and the like. The scattered light is divided into two through a lens 17-a color separating mirror 27 corresponding to the wavelengths. Images of particles in the blood flow of the ocular fundus Er of the eye formed by the respective scattering lights are focused separately on detecting apertures 28, 30. The light beam of the images of particles passing the apertures 28, 30 are detected by photomultipliers 29, 31, respectively. A coorelative function of the output signals from the photomultipliers 29, 31 is calculated by a correlation detector 32. The flow velocity is calculated by a signal processor 33 based on the calculated result.

Title: Power amplifier
Inventor: OYABU SHUJI
IPC: H03F3/20
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To allow a user to perform power amplification with high reliability without operating re-adjustment or routine check in replacing a part by providing a means for controlling the phase of an input signal so that the phase difference of plural signals inputted to a power amplifying means can be made minimum, based on the absolute value of the phase difference and the advance or delay of the phase. SOLUTION: When two signals for controlling a phase difference to be compared are inputted from a branch output part 300, a phase difference calculating part 500 calculates the phase difference of the two input signals. When the two signals for controlling a phase difference to be compared are inputted from the branch output part 300, a phase difference advance or delay judging part 600 judges whether the phase is advanced or delayed, based on the two input signals. A phase control part 700 judges what degree of the phase is advanced or delayed in the two signals based on the signals inputted from the phase difference calculating part 500 and the phase difference advance or delay judging part 600, and feedback controls the phase of a signal inputted to a power amplifier 200 so that the phase difference and the phase advance can be made the minimum.

Title: Digital-analog converter
Inventor: AMAMIYA YOSHIHITO
IPC: H03M1/10
Filed: 1978-06-02
Abstract: PURPOSE: To increase the accuracy by selecting the diode with short-circuiting and thus minimizing the error in case the reference current value is out of the setting ideal value after end of the manufacturing processes.  
     CONSTITUTION: In case output current Iout drawn out from the addition line is out of the setting ideal value for the constant current source consisting of constant current transistor TrQ 6 , the correction is given in the following method. The current of correcting current sources TrQ 0 ∼Q 3  are set to I 0 , 2I 0  and 4I 0  each when the current flowing to Q 0  is I 0 . Now if the laser beam is radiated to diode D 1  and D 2  to secure a short, the correcting current features as I 0  + 2I 0  = 3I 0 . If diode D 4  is short-circuited under these conditions, the current of 3I 0  flows to TrQ 4  as well as to Q 5 . And current I 1 ' featires as I 1  + 3I 0  since it flows in at the collector node of Q 6 . While if diode D 4  is not short-circuited with D 5  short-circuited, I 1 ' features as I 1  - 3I 0 . Through this operation, D 1  D 5  are selected with short-circuiting, and thus current I 1 ' can be varied in the range of I 1  ± 7I 0 .

Abstract: PURPOSE:To reduce the labor for control by transmitting code data, outputted every time the state of an image forming process is changed, to a main controller in series by another control which constitutes a subordinate controller together with discrimination data. CONSTITUTION:Every time the operation of respective parts of a copying machine is changed, a master CPU 40 sends the code data corresponding to the state after the change to a CPU 42 which constitutes the subordinate controller. The code data are stored temporarily in a RAM 47 with which the CPU 42 is equipped and the CPU 42 requests a host computer 57 to send data. The host computer 57 which constitutes the main controller sends the code data stored in the RAM 47 to the host computer 57 together with the ID code of the copying machine for which the CPU 42 is connected. The host computer 57 displays the state corresponding to the code data in the field of the copying machine corresponding to the ID code with the data sent from the CPU 42. Therefore, the detailed operation state of the copying machine can be controlled and the labor for the control is reduced.

Abstract: PROBLEM TO BE SOLVED: To enable an optical head to retreat by simple constitution without dividing a mechanical chassis into two by extending a part of a guide means to the outside from the outer circumferential section of a cartridge and retreating a second head to the extending section. SOLUTION: When a second disk D2 is inserted into a device body H, the insertion is detected by a detecting sensor 27, and the detecting signal is transmitted to a CPU 25. Consequently, a driving motor 7 is driven, a screw shaft 5 is rotated, and an optical head 3 is moved from the place of a retreat to the place of information processing. When the processing of the disk D2 is completed, the motor 7 is rotated reversely, and the head 3 is retreated to the place of the retreat. When a cartridge K, in which a first disk D1 is housed, is inserted, on the other hand, the insertion is detected by a detecting sensor 26. The motor 7 is not driven and the head 3 is left as it is positioned at the place of the retreat at that time. The cartridge K is taken to a specified place by a loading mechanism, and information is processed against a first optical head 2 by opening a shutter S.

Abstract: PROBLEM TO BE SOLVED: To enable changeover of an intermittent frequency according to the condition of a load by providing a circuit which obtains an oscillation output from a timer circuit by charging and discharging a capacitor connected to a power line, and changing divided outputs of a frequency divider circuit provided in the timer circuit by a control signal. SOLUTION: A switching power circuit is provided with a timer circuit for forming an intermittent frequency in a stand-by state. In the timer circuit, a charging/discharging circuit performs oscillation by a voltage VD applied from a primary side, if supply of a voltage Vc from the secondary side is interrupted.
