Title: Signal selector
Inventor: HORI SHINICHIRO
IPC: G05B13/02
Filed: 1992-02-21
Abstract: PURPOSE:To flexibly change / adjust a set value against the change of an objective system by automating the decision of a set value for switching signals. CONSTITUTION:A signal from a signal measuring object system 11 is preprocessed by a signal recorder 13, and the result is recorded in an output file 14 and transmitted to an analyzer 15. The recorded information in the output file 14 is read, statistically processed and recorded in an output file 16 by the analyzer 15. The switching set value is calculated from the analyzed result recorded in the output file 16 and outputted to a switching set value changer 18 by a learning controller 17. The switching set value changer 18 changes the switching set value of a signal selector 12 with the output of the learning controller 17 as the new set value. A learning diagnostic device 19 reads the output of the analyzer 15 from the output file 16 and diagnoses whether the signal measuring object device 11 is in the normal or abnormal state and when any abnormality is generated, an alarm is issued by an alarm system 20.

Title: Flow rate/liquid level measuring apparatus
Inventor: MIURA KIYOHIDE
IPC: G01L13/00
Filed: 1989-02-16
Abstract: PURPOSE:To achieve a suppression of error owing to a response speed in a pressure transmission path by providing a differential pressure transmitter, a pressure converter and a time constant control circuit to measure variations in a flow rate quickly while increasing a time constant of a signal against a large change in static pressure. CONSTITUTION:In the starting of a pump 1, with the closing of a switch 10, the pump 1 is accelerated with a motor 11 to increase a process flow rate gradually within a process piping 2 while a static pressure rises sharply near an orifice 3. In response to this condition, an output of a change in static pressure of a pressure computing device 15 increases rapidly via a pressure converter 14 and it exceeds a set value in a static pressure setter 16. Hence, a changeover switch 12a of a time constant control circuit 13 is opened by the resulting output signal and switch 12b is closed. At this point, a flow rate increases rapidly as outputted from an arithmetic device 6 via a differential pressure transmitter 5 being transmitted from instrumentation pipings 4a and 4b from both upstream and downstream sides of the orifice 3. Then, a flow rate surpassing a set value 9 is outputted owing to an error caused by response speed difference among the high pressure and low pressure sides of the pipings 4a and 4b, the transmitter 5 and the like.

Abstract: PURPOSE:To detect easily an error, and also to improve the probability for obtaining a correct data, by holding the same data in odd parts of three parts or more, comparing the respective holding data, and obtaining a correct data by a decision of majority. CONSTITUTION:A 4-bit data 9 is stored in RAMs 1, 2 and 3 by a write signal. Subsequently, outputs of the RAM 1 and 3 are inputted to an exclusive OR gate group 4a, and as for a data which is read out by a read-out signal 12, exclusive OR of the corresponding bit which is to be in the same state originally is calculated. The output of the gate group 4a is inputted to an AND gate 5a. In such a way, if the contents of the corresponding bits of the RAM 1 and 3 are all equal, each output of the gate group 4a goes to an L level, and the output of the AND gate 5a goes to an H level. As a result, in a tri-state buffer group 6, from a buffer which is connected to the output terminal of the RAM 1, the 4-bit data of the RAM 1 is outputted as a correct 4-bit data 11.

When the switches 12, 13 are turned ON simultaneously, the switch 12 is preferred by a control circuit 2. It is only when an electric power is turned ON and also a printer is reset at the time of initialization that initialization is performed by the switch 12.

IPC: B65H7/04
Filed: 1993-02-25
Abstract: PURPOSE: To provide an apparatus for detecting a stack of sheets at a preselected location. CONSTITUTION: In an apparatus, an air jet from a nozzle 120 is directed towards an edge of the stack of sheets at a preselected location, and a pressure transducer 124 is located at the preselected location and positioned to have the air jet at impact thereon.

Title: Execution hysteresis storage device
Inventor: NAKANO HIROTAKA
IPC: G06F11/07
Filed: 1989-02-17
Abstract: PURPOSE:To leave the execution hysteresis of an initial exception even if a second exception occurs while a fault restoring function is operated by permitting a mask resetting code existing in a micro instruction to mask the prescribed quantity of a tracer memory. CONSTITUTION:When the exception occurs in a device and the fault restoring function operates, a mask setting code 5 sets a mask signal FF existing in a combination circuit 9, which executes masking from the address J of the tracer memory 7 to an address I which is retroactive by a prescribed quantity. In such a state, the tracer memory 7 is circularly used in a state that addresses from the address I to the address J are excluded. Thus, the execution hysteresis of the first exception can be left by learning the content from the address I to the address J even if the device stops by the second exception which has newly been generated while the fault restoring function is operated.
