Title: Automatic adjusting method for control constant of pid controller
Inventor: EBISU KOJI
IPC: G05B13/00
Filed: 1986-06-19
Abstract: PURPOSE:To improve the controllability of a control system by increasing a proportional gain when a vibration period P is more than a constant rate longer than the integration time of a PID controller. CONSTITUTION:A manipulated variable (u) outputted by the PID controller 1 is inputted to a controlled system 2, whose output (y) is inputted to the PID controller 1 as deviation (e) which is a difference from a target value (r), thus constituting a feedback control loop. Further, the deviation (e) is inputted to an automatic constant adjustment part 3, which determines the proportional gain Kp to automatically adjust the control constant of the PID controller 1. At this time, when the period P of vibrations due to transient deviation is more than the constant rate longer than the integration time Ti set in the PID controller, the proportional gain Kp is increased by a constant rate. Consequently, the automatic adjustment is performed without causing any oscillation state, so deterioration in controllability due to the adjustment is precluded.

Title: Alloy slurry producing device
Inventor: NUMATA YOSHIMICHI
IPC: B22D27/20
Filed: 1978-11-22
Abstract: PURPOSE: To give strong shearing force to the alloy of a solid-liquid coexising area and produce alloy slurry at large volume with good efficiency by rotating a revolving shaft body and a scraper plate concentrically respectively in the opposite directions.  
     CONSTITUTION: Alloy is melted in the crucible 4 installed in an electric furnace 8. At the time of a suitable melting temperature, a revolving shaft body 6 and a scraper plate 5 are dipped in molten metal and with a spacing being provided between both, these are rotated concentrically respectively in the opposite directions.  As a result, the dendritic crystal in the alloy slurry 7 is parted and becomes round  prticles by receiving strong shearing force, resulting in that these particles disperse in the fine structure which had been liquid at the time of casting.

Title: Checking circuit of personal code number
Inventor: NAKAMURA TATSUYA
IPC: G07D9/00
Filed: 1983-08-05
Abstract: PURPOSE:To realize a device with which a user can recognize a digit feeding mistake of his/her code number by calculating the difference between a stored code number and an input number and dividing this difference by nine to detect that the residue is equal to zero. CONSTITUTION:When an ID card is put into a ID card reading part 8, the information on the code number stored on magnetic stripes is stored to a memory part 1 for ID card code number. When a user feeds the numeric characters of four digits through a ten-key part 9, these characters are stored to a ten-key input number memory part 2. Then the difference of contents is calculated by a subtraction part 3 between the parts 8 and 2. When this calculated value is equal to zero, a code number coincidence detecting number 4 is delivered to an external circuit. No signal 4 is delivered if the user makes a mistake to feed the digits of his/her code number. Then the result of calculation of the part 3 is divided by nine at a division part 5, and this residue is delivered to a residue detecting part 6. An error of input order of digits is suspected in case the residue is equal to zero. Thus a display part drive signal 7 is delivered to a display part 10 to inform the possibility of an error to the user. Both signals 4 and 7 are not delivered in case the input of the secret number is totally wrong.

Title: Rice milling device
Inventor: ABE AKIFUMI
IPC: B02B3/08
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To surely discharge bran to the outside of a main body case. SOLUTION: When rice grains are housed into a rice milling vessel 17 and an electric motor 5 is driven, rice milling vanes 24 rotate. Rice milling is executed by rubbing of the rice grains against each other or the rice grains and the rice milling vessel 17. When the bran is discharged into a recessed part 3, the bran is rotated while receiving force in a centrifugal direction within the recessed part 3 by the centrifugal force and wind pressure generated by the rotation of bran discharge vanes 12. As a result, the bran is surely sent from the recessed part 3 into a bran discharge port and is discharged to the outside of the main body case.

Title: Noise reducer
Inventor: ARAI NAOHISA
IPC: H04N5/21
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To eliminate inter-field low frequency noise in data obtained by decoding image data subjected to DCT coding with an inexpensive configuration. SOLUTION: A decoded luminance signal is fed to a subtractor 24, in which a noise component is eliminated. An interleave circuit 25 decimates the decoded luminance signal at a rate of 1/4. A subtractor circuit 26 subtracts an output of a field memory 28 from an output of the decimation circuit 25 and a subtraction output is fed to a nonlinear limiter 29. A noise component extracted by the nonlinear limiter 29 is subtracted from the output of the decimation circuit 25 at a subtractor 27 and a subtractor output is given to the field memory 28. An interpolation circuit 30 interpolates the extracted noise component into the original rate and an interpolation output is fed to the subtractor 24. The subtractor 24 eliminates the noise component from data of a main line group.

Title: Carburettor for internal-combustion engine
Inventor: HASEGAWA KUNIO
IPC: F02M1/14
Filed: 1982-08-18
Abstract: PURPOSE:To prevent the deterioration in the economy of fuel due to frequent operations of an accelerator by a method wherein a valve is provided so as not to cause a choking effect when it is closed and the opening and closing thereof are controlled so that the vacuum of a suction pipe is not shifted to the neighborhood of atmospheric pressure as compared with a predetermined value. CONSTITUTION:Upon idling or when the opening degree of a throttle valve is small, the vacuum of the suction pipe shows a value near vacuum, therefore, an operating rod 12 is retreated to the left, a pivoting member 7 is pivoted clockwise and the valve member 3 is located at the fully opened position thereof. When the throttle valve 4 is opened further from this condition and the vacuum of the suction pipe is closed to the atmospheric pressure, the operating rod 12 is advanced to the right by the resilient force of a spring 16. As a result, the pivoting member 7 is pivoted counterclockwise by the force of the spring 9 and the valve member 3 is closed. However, air flows in some degree even if the valve member 3 is fully closed, which condition is different from the case of a choke valve. Accordingly, excess fuel will never be supplied by even a violent operation of the throttle valve and the economy of the fuel may be improved.

Title: Radio terminal equipment
Inventor: ONISHI SHINJI
IPC: H04W52/02
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To extend the service life of a power supply by configuring the radio terminal equipment such that an output of a control signal is stopped when a preset limit time elapses during the output of the control signal so as to limit an operating time of a ringer within a prescribed time thereby reducing power consumption. SOLUTION: An EEPROM 12 stores in advance a limit time for which a control section 9 can continuously output a control signal to a ringer circuit 10. When the control section 9 receives data denoting a call coming from a base station from a decoding section 7, the control section 9 starts outputting the control signal to the ringer circuit 10 and also reads the limit time stored in the EEPROM 12 and sets it to a timer 13. When the control section 9 sets the limit time to the timer 13, the timer 13 starts count-down and provides an output of a time-out signal to the control section 9 when the timer 13 expires. When the control section 9 receives the time-out signal from the timer 13, the control section 9 outputs a ring-off signal to the base station to stop the control signal to the ringer circuit 10.
