Title: Plant monitor controller
Inventor: YOSHIOKA MASAHIRO
IPC: G05B9/02
Filed: 1988-07-29
Abstract: PURPOSE:To prevent the plant troubles caused by the misoperations of operators by stopping the plant working based on a stop pattern for abnormality which is previously set at a control computer. CONSTITUTION:A control computer 1 usually performs the monitoring and operating jobs of a plant 7 and then transmits an abnormality signal to a controller 4 in case such serious abnormality occurs that disables the monitor/operation function. The controller 4 usually performs a logical arithmetic with a digital input signal 5 received from the plant 7 and then performs various arithmetics including a PID arithmetic, etc., with an analog signal 5 respectively. Then the controller 4 outputs a control signal to the plant 7 to perform the due control. When the abnormality signal of the computer 1 is received, the working of the plant 7 is stopped based on a stop pattern stored in a memory. Furthermore the plant stopping processing under execution is temporarily stopped and the plant 7 is reset to the state set before input of the abnormality signal in case the plant abnormality signal is received while the plant 7 is kept in a stop state. Then the stopping processing of the plant 7 is reopened after the stop pattern is automatically changed.

Title: Error check in polarographic urinalysis
Inventor: NAKAMURA KAZUHIRO
IPC: A47K13/30
Filed: 1995-06-30
Abstract: PURPOSE: To exclude abnormal values and to obtain correct analytical results quickly by means of constitution in which only the calibration of flow cell outputs and the computation of concentrations are repeated. CONSTITUTION: If an enzyme in the enzyme fixing film of a flow cell 94 degrades abnormally too early, an urine sugar level is displayed as being too low. If the testee doubts about it and gives a command to check error by way of an input switch 204, a microcomputer 200 in a main control unit 56 sends a command to start calibration to a microcomputer 212 in an auxiliary control unit 58 to initiate replenishing calibration. A calibration liquid is fed to a flow cell 94, and a new flow cell output M1 for the calibration liquid is transferred from the unit 58. The microcomputer 200 renews the output M1, recomputes the urine sugar level in accordance with the renewed output M1 and the flow cell output M2 for the previous urine sample, and displays a new urine sugar level.  Since the error check is performed by repeating only the replenishing calibration and computations without performing analysis again, the testee is not restrained during that period. Also, a correct urine sugar level can be obtained in a minimum time.

Title: Controller for driving expansion and contraction of motor-driven antenna
Inventor: SUGA MITSUHIRO
IPC: H01Q1/10
Filed: 1982-10-27
Abstract: PURPOSE:To remove the useless consumption of electric power and to expand and contract an antenna efficiently by differentiating the whole length of the antenna by the number of pulses generated from an oscillator and counting the number of pulses to control the expansion of the antenna. CONSTITUTION:The number of counts set up by the positions of antenna switching terminals F, H and switches S1-S4 is outputted from a decoder 2A to a comparator 4A. The output of a counter 3A is ''0'' until the time just before operation, the comparison of outputs between the decoder 2A and counter 3A by a comparator 4A is A>B and a pin 13 is the high level. A transistor (TR) 1 of a control circuit 6A actuates a relay Re1 and a motor causes the antenna to extend. Simultaneously, a pin 3 of the comparator 4A is turned to the low level and an oscillation circuit 5A is oscillated through an inverter I. The counter 3A counts up the number of pulses of the oscillation circuit 5A, and when A=B is satisfied, the pin 13 is turned to the pin 3 and the TR1 of the control circuit 6A is turned off, stopping the motor. Since the pin 3 is turned to the high level simultaneously, the oscillation circuit 5A stops operating. Thus, the expansion of the antenna can be performed efficiently.

Abstract: PROBLEM TO BE SOLVED: To improve lubricating performance even in an oil supply source nonexistent place by arranging a plate to form an oil reserving part so as to soak a part of a two-wheel/four-wheel switching mechanism by oil by making the oil stay in a rib.

CONSTITUTION:Fine glass particles are produced by a flame hydrolysis method using gaseous H2 and O2 for combustion and gaseous starting materials such as SiCl4 and GeCl4, and the particles are deposited in the axial direction to form a porous base material 13. This base material 13 is put in a ringlike resistance heating furnace 12, and it is moved upward and downward under rotation with a lift 11 to repeat the local heating of the material 13 twice of more over the full length in an atmosphere contg. a chlorine-base gas. A proper amount of GeO2 is volatilized from the material 13 by the local heating, so the refractive index distribution is modified or controlled. The porous base material 13 is then converted into transparent glass by sintering in an atmosphere contg. no chlorine- base gas to obtain a base material for an optical fiber having a desired refractive index distribution.

Title: Variable structure control method
Inventor: FUJIKAWA ATSUSHI
IPC: G05B11/36
Filed: 1992-07-16
Abstract: PURPOSE:To vary the PI constant and the primary delay filter time constant of an equivalent disturbance observer and to attain a high function for the control response by multiplying the deviation value between the command input and the state input of a controlled system and the differential value of the deviation value by a weight coefficient and adding together these multiplied values. CONSTITUTION:For instance, the velocity deviation and its differential value are multiplied by a weight coefficient and these multiplied values are added together. Thus a parameter E is obtained. The function generators 4-6 calculates a proper P (proportion) constant, an I (integration) constant, and a primary delay filter time constant based on the parameter E respectively. Then each output of the generators 4-6 is sent to the corresponding parts of a PI controller 1 and an equivalent compensating part 3 with the velocity deviation defined as an input. Thus the output of generators 4-6 are changed into a proper proportion constant, an integration constant, and a filter time constant respectively. In such a way, the proportion time constant, the integration constant, and the primary delay filter time constant of an equivalent disturbance observer can be varied in accordance with the operating states. Thus it is possible to improve the robust properties and the stability against the setting fluctuation and the load fluctuation.
