Title: Non-linear type d/a converter
Inventor: KATOU KUNIHARU
IPC: H03M1/84
Filed: 1979-03-02
Abstract: PURPOSE:To increase the conversion accuracy of the D/A converter with addition of the correcting function and by using the programable code converter and also changing the analog signal source into the high frequency. CONSTITUTION:The digital coded signal is supplied to input terminals 1-n of PROM21, and at the same time the clock pulse is supplied to input terminal 29 to start reference pulse source 24. The pulses sent from source 24 are counted by counter 23. At the same time, the integration is given to the high-speed pulses sent from high-speed reference pulse source 25 which is started by the pulse of source 24 at integrator circuit 27 and via switch 26, and thus the high-speed pulse is converted into the pulse which is turned on and off in a high speed. Then the pulse to control switch 26 is delivered from logic digital comparator 22 at the time point when the digital code of counter 23 coincides with the output digital code of PROM21. Thus the input of the high-speed reference pulse is cut off to circuit 27, and the output of circuit 27 is applied for the discharge characteristics of the exponent function. And the level of the characteristics is held at sample holding circuit 28, thus increasing the conversion accuracy of the converter.

Title: Picture draw-in device
Inventor: SUZUKI TOSHIHISA
IPC: G06K9/00
Filed: 1978-03-08
Abstract: PURPOSE: To reduce the jitter occurring when the picture image is drawn in by reading out the video signal from VTR with the synchronous signal from outside to be then written into the analog memory capable of controlling the timing and then reading out the written video signal via the synchronous signal.  
     CONSTITUTION: The video signal equivalent to one picture frame sent from VTR1 is written into analog memory 2 which is capable of controlling reading timing via the synchronous signal given from outside. Then the video information of memory 2 is read out repetitively by the steady synchronous signal supplied from the video input device to be turned to the video signal. Thus, the jitter is eliminated for the time axis of the scanning line at the same position where the frames of the video signals differ, obtaining the video signals featuring the repetitive property. This video signal is then supplied to picture input device 3, and the digitized video signal is transferred to digital computer 4. The digitization can be carried out in a steady way even with the vertical sampling system because of the repetitive property of the signal.

Title: Electrostatic digitizing panel and its noise reducing method
Inventor: UIRIAMU KEI PETEI
IPC: G06F3/041
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To reduce the noise interference of an electrostatic digitizing panel, by amplifying the signal when a an object is close to the digitizing panel with an amplifier, detecting a noise impulse connected to a resistance layer, and disconnecting the input of the amplifier from the resistance layer according to the detection. SOLUTION: Currents flowing to corner wires 20a-20d are caused substantially by the object which is close to the digitizing panel. When a noise detector 40 detects a noise phenomenon on the corner wire 20d, a trigger signal is sent to a blanking pulse generator 42 through a line 62. A control signal generated on the line 64 changes a switch from an opening state to a closing state, and consequently the input of the amplifier 36d is disconnected from the output of an I/V converter 34d and the input of a signal converter 38d is disconnected from the output of the amplifier 36d.

However, the actuating/finishing meta-rule of the meta-rule set G depends on a method for an inference start and an inference end of the expert system, therefore, the part of a start notice and an end notice is generated manually.

Filed: 1984-02-14
Abstract: PURPOSE:To form a transmission line with circuit and, at the same time, to surely transmit the operation of sensors, by transmitting the phenomena detected conditions of the sensors by using continuous waves having different time intervals. CONSTITUTION:Each output of a sensor group SO is supplied to a time assigning circuit composed of preset counters 21-2m through an NAND gate 20. Therefore, a continuous wave having a length corresponding to a reference time is generated from an AND gate 42 when any of the sensor group SO does not generate any detect signal. On the ohter hand, when some sensors of the sensor group SO generate detect signals, the AND gate generates continuous waves of time intervals corresponding to the number of the sensors. The output of the gate 42 is sent to a receiving terminal R through a transmission line 50 and each signal is displayed on a display L0 when no detect signal exists and on displays L1-ln, the number of which corresponds to the number of the sensors, when a detect signal exists after separation. Therefore, the transmission line can be formed with one circuit and, at the same time, operations of the sensors can be transmitted surely.
