IPC: G05B13/04
Filed: 1987-02-17
Abstract: PURPOSE:To momentarily drive a manipulator without obstructing acceleration or deceleration of a mechanism to be driven, based on an operation command, while performing the vibration isolation of the mechanism to be driven, by allowing a driving speed of a motor and a moving speed of the mechanism to be driven to coincide with each other. CONSTITUTION:A vibration system of a controlled system consisting of a motor 8, a mechanism 9 to be driven, and a transfer mechanism for connecting the motor and the mechanism to be driven is modeled. To a state observing circuit 30 for estimating an internal state of this vibration system model, a motor current detecting signal of a driving motor 8 corresponding to an operation command, and an acceleration detecting signal of the mechanism 9 to be driven are inputted. An estimated value X of a speed component X of the internal state of the vibration system model of the controlled system is outputted, this state estimated value X is brought to a feedback control to an input side of the motor 8 through a gain adjusting circuit 22 and a feedback compensating circuit 31, or a state signal amplifier circuit 32, and a driving speed of the motor 8 and a moving speed of the mechanism to be driven 9 are allowed to coincide with each other. In such a way, a vibration of the mechanism to be driven can be decreased.

Title: Semiconductor moisture sensor
Inventor: MIYAI YOSHIO
IPC: G01N19/10
Filed: 1989-02-13
Abstract: PURPOSE:To achieve a higher stability eliminating a zero drift by using a crosslinked polymer material as moisture sensitive stretch film material to prevent a deformation owing to a slide between molecules. CONSTITUTION:An Si pellet 1 has a diaphragm 2 worked by etching and a piezo-electric resistor 3 is formed on the surface of the diaphragm 2. Moreover, a moisture sensitive material 4 is applied in a film on the back side of the diaphragm 2. This semiconductor sensor utilizes a stretching phenomenon of the moisture sensitive material 4 due to an atmospheric moisture and applied in a film on the diaphragm 2 made of Si to convert the stretching of the material into an electrical signal. The moisture sensor detects a distortion of Si with a balanced force between the moisture-sensitive material 4 and the diaphragm 2. As the moisture sensitive material 4 is made up of a crosslinked polymer material, a two-dimensional construction can have a three-dimensional coupling to eliminate a slide between the molecules. This also gets rid of a permanent deformation otherwise caused by a creep, thereby stabilizing an output of the moisture sensor as well.

Title: Facsimile equipment
Inventor: YAMAMOTO TOSHIFUMI
IPC: H04M1/27
Filed: 1990-02-15
Abstract: PURPOSE:To utilize a dialing function such as an abbreviation dial function even from an external connection device such as a telephone set by discriminating a type of a dial number, converting the dial into other kind of dial number and sending the converted number to a line through a line connection means. CONSTITUTION:When a control section 5 monitoring a dial number by a dial detection section 4 discriminates the dial number to be a direct dial, the control section 5 applies switching control so that an external device connection section 2 is connected to a line connection section 1. Moreover, when the dial is discriminated to be an abbreviation dial, a number conversion section 7 converts the abbreviation dial given from the dial detection section 4 into a usual opposite dial number and outputs the number to a dialing section 8. Then the dialing section 8 sends the opposite dial number from the number conversion section 7 to a telephone line through the line connection section 1 to apply connection control of the line. Thus, a special dialing function such as the abbreviation dial function is utilized from a device such as a telephone set connected externally.

Title: Low voltage detection circuit
Inventor: NISHIURA HARUO
IPC: G01R19/165
Filed: 1990-02-15
Abstract: PURPOSE:To stabilize operation at a low voltage while reducing the number of elements by detecting a low voltage with one MOSFET and resistance each, only while compensation for temperature is made possible to perform a waveform shaping of outputs thereof with a buffer. CONSTITUTION:This circuit is made up of a resistor stage having a first P channel MOSFET 1 and a resistor 4, and a buffer stage having a second PMOSFET 2 and an N channel MOSFET 3. Since the FET 1 is ON when a power source terminal 5 is at a sufficiently high voltage, a low level is outputted at an output terminal 7 when a resistance value of the resistor 4 is large sufficiently. When the voltage at the terminal 5 lowers, the ON resistance of the FET 1 increases, and it exceeds the resistance value of the resistor 4 when a certain potential is reached. Thus, when the buffer stage is in operation, the signal at the terminal 7 is inverted to be a high level, and the current voltage value is detected.
