Title: Servorecorder
Inventor: TANABE TOMOYUKI
IPC: G01R17/06
Filed: 1977-11-08
Abstract: PURPOSE: To protect the servo motor by preventing the maximum power from being fed into the motor, by detecting the overstroke and restriction of a pen with the output voltage of summing amplifier which adds the input voltage and feedback voltage from potentiometer.  
     CONSTITUTION: An amplifier A 1  functions as a summing amplifier which adds the input voltage ei from input eteminal IN and feedback voltage e f  delivered by potentiometer PM. It is so designed that the output of the summing amplifier A 1  is reduced to zero by adding negative feedback voltage ef through rotations of motor M. When an input exceeding the full scale voltage is applied as input e f  or pen P is restricted, the output voltage eA of the summing amplifier A 1  is saturated, which is applied to an integrator IG, which composes a protective circuit MP. Thus, reducing the voltage applied to coils W 1 , W 2  of the motor M, and decreasing the current flowing in the coils W 1 , W 2 , the motor M is protected.

Title: Quantizer
Inventor: KANEAKI TETSUHIKO
IPC: H03M7/36
Filed: 1990-05-24
Abstract: PURPOSE:To always operate the circuit stably without oscillation by controlling an upper limit and a lower limit of a local quantizer output in a noise shaping quantizer to be expanded or reduced based on the state of a differentiating device. CONSTITUTION:A local quantizer 23 varies an upper limit and a lower limit of its output in response to the state of a differentiating device 10, in such a case, the output of the differentiating device 10. For example, when the control input of the differentiating device 10 is +1, the output upper limit is +2 and when the output of the differentiating device 10 is -1, the output lower limit is -2. Thus, even when the input of >=0dB in a conventional quantizer is sup plied to the quantizer, a quantization error Vq1 generated in a main loop is not monotonously increased and even when a larger input is supplied, the quantizer is normally operated. While the entire output of the quantizer is suppressed to 7 values of -3 - +3, the gradation is not increased in comparison with that of a conventional quantizer.

IPC: G05B23/02
Filed: 1991-06-06
Abstract: PURPOSE:To diagnose a failure without preparing a sensor for failure diagnosis by extracting feature variables from the I/O data of a control device and comparing the extracted feature variables with a previously set normal feature variable distribution range. CONSTITUTION:Input/output(I/O) data, i.e., the data of a control variable (y) and a manipulated variable (u), are stored in a data storing part 10 and plural feature variables are extracted from these stored data. The distribution of respective extracted feature variables is found out, and when the distribution has no dispersion, the distribution is decided as a normal state and a normal feature variable distribution range is set up. A decision part 12 compares respective feature variables extracted by a feature variable extracting means 8 with the normal distribution range set up by a setting part 11. The abnormality of I/O data is decided by combining combined results and a corresponding abnormal signal is outputted as a decided output. Thus failure diagnosis can be attained without preparing a sensor for failure diagnosis.

Accordingly, even when there is no consistency in the keyword and it is difficult to designate the suitable keyword or the keyword added to the data being a purpose is not clear, possibility for success to tightly close the data being the purpose, is increased only by designating the keyword with meaning to relate with the contents of the data which are the purpose. Thus, without repeatedly designating the keyword, the data, which are the purpose, can be efficiently retrieved.

Title: Optical transmission and reception circuit
Inventor: SAKAMOTO FUKUMA
IPC: H04B10/556
Filed: 1981-08-28
Abstract: PURPOSE:To decrease the power consumption of a photoelectric element, by generating and transmitting a plurality of optical pulse trains corresponding to one pulse of a transmission signal, converting them into electric pulses at a receiving side and restoring them into transmission signal pulses with a delay of prescribed time. CONSTITUTION:In inputting a transmission signal pulse SD, DELTAT of width, a monostable multivibrator IC1 generates a pulse having a width determined with a resistor R1 and a capacitor C1, e.g., T1=27 mus and a monostable multivibrator IC2 is driven from the output terminal -Q. The IC2 generates a sub-pulse having 3 mus (T2=C2R2) of width to illuminate a light emission diode LED and the signal is transmitted via an optical fiber OF. The sub-pulse is transmitted for n pulses during the DELTAT with T1+T2 of period and T2/T1+T2=0.1 of duty cycle. At the receiving side, this optical pulse is converted into an electric signal, which is shaped to drive a monostable multivibrator IC3. The IC3 drives a monostable multivibrator IC4 with a pulse in which the start point of the pulse has a delay of prescribed time of C3R3=T3=60mus. The IC4 restores the pulse into the pulse, DELTAT of width, by making a pulse delay for a prescribed time as the start point and extended by C4R4=T4=57mus.

Filed: 1995-06-01
Abstract: PURPOSE: To provide a document reader capable of storing the data of a white level without increasing a manufacturing cost by providing a reference line for discriminating the reading range of an original in a main scanning direction at a body to be detected so as to decide a thredshold. CONSTITUTION: When a pair of left and right black lines 28a and 28a at the body to be detected 28 is not discriminated, an LED lamp provided at a control panel is turned on to indicate that a cover body 19 is not completely shut off. Whenever a user turns on the power switch of a facsimile device and starts it, the black line 28a of the surface of the body to be detected 28 is discriminated by a CCD scanner 22, so that it automatically discriminates the shut-off state of the cover body 19. Also, the data of the white level on the surface of the body to be detected 28 is restored in a lamp every time the power switch is turned on and it is started, so that it does not exclusively possess the memory area of an expensive EEP ROM as heretofore. Therefore, an independent sensor for detecting the shut-off state of the cover body 19 is unnecessitated.

Title: Solid-state image pickup element
Inventor: NAKAI MASAAKI
IPC: H04N5/335
Filed: 1984-07-02
Abstract: PURPOSE:To eliminate fixed pattern noise due to the variance of storage capacity by setting the potential of the storage capacity to a specific reference potential when not only the electric charge of a false signal is pulled to the external but also the electric charge of the signal is read into a charge transfer element. CONSTITUTION:A signal charge Qs is stored in the storage capacity of a photodiode 1, and a false signal charge QB is stored in the capacity CV of a vertical signal line 4. Excess electrons under the capacity 9 are flowed to the signal line 4 and are joined with the charge QB. The charge stored in the signal line 4 is flowed under the capacity 9. The charge QB is absorbed by an external VR. At this time, the potential under the capacity 9 is clipped with a potential equal to a difference between a high-level voltage phixH of the gate pulse of a horizontal switching MOSFET5 and a threshold voltage Vt(phix) of the FET5. Meanwhile, the charge Qs is transferred to the signal line 4 and is transferred next to the capacity 9. Next, the charge Qs is transferred to a horizontal reading charge transfer device 6 and is read out to the external. Thus, the potential under the capacity is set to the same potential when not only the charge QB is pulled out to the external VR but also the charge Qs is read in.
