Inventor: KUBO OSAMU
IPC: C01G9/02
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To provide a producing method, capable of more readily preparing various kinds of functional oxide powder having good dispersibility and narrow width of particles and suitable for preparation of functional thin film due to coating. SOLUTION: A raw material component containing constituent elements of functional oxide powder is mixed with a glass forming component and the mixture is heated and melted and the resultant melt is quenched to prepare an amorphous material. Then, the amorphous material is subjected to heat treatment to deposit fine crystals of functional oxide in glass mother phase and the glass mother phase is dissolved by cleaning treatment to separate and extract the objective functional oxide powder. A basic oxide expressed by the general formula R2 O (R represents at least one kind of element selected from Na and K) (A) and at least one kind of acidic oxide selected from B2 O3 and P2 O5 are used as the glass-forming component.

IPC: H04L7/08
Filed: 1982-01-11
Abstract: PURPOSE:To transmit a synchronizing signal through a frame synchronization system for digital transmission without reference to transmitted information, by inserting the frame synchronizing signal into the latter half zero part of the starting bit of an RZ code transmitting code. CONSTITUTION:The data DATAs and timing CLOCKs of an input NRZ code are ANDed by an AND circuit 11 to perform conversion to the RZ code having the latter half zero part of each bit.

Title: Video signal reproducing device
Inventor: TAKAYAMA NOBUTOSHI
IPC: G11B21/10
Filed: 1983-01-11
Abstract: PURPOSE:To perform excellent tracking even when there is some level difference between reproduced pilot signals by providing a compensating means which compensates frequency characteristics in the band of the pilot signal of a reproducing head and an AGC amplifier which holds the reproduction level of the pilot signal constant. CONSTITUTION:The pilot signal of a reproduced signal is passed through a band- pass filter 16 to obtain only its band, which is inputted to one input terminal of a multiplier 19 through an equalizer 17 and the AGC amplifier 18. Then, signals of difference frequencies F1 and F2 between an oscillation frequency signal and crosstalk components of the reproduced pilot signal are obtained from the multiplier 19. Then, a signal of frequency close to the frequency F1 is extracted by a band-pass filter 20 and a signal of frequency close to the frequency F2 is extracted by a band-pass filter 22; and both are detected by detecting circuit 21 and 23 respectively. Their detection outputs are amplified differentially by a differential amplifier 24, inverted by an inverting amplifier 25, and inputted to an amplifier 27 alternately to control head tracking.

Title: Vehicle vibration adaptive control method and its device
Inventor: ICHIKAWA HIROYUKI
IPC: G05B13/02
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal sound to occur when a vehicle suddenly starts off or accelerates by calculating the frequency variation between samplings one after the other, comparing the variation with a constant according to the acceleration evaluation condition, and attenuating the input signal with an adaptive filter having a smaller coefficient if the variation is found larger than the constant. SOLUTION: When a vehicle is in operation, a control section 31 samples the frequency based on signals sent from a revolution sensor 12 and calculates frequency variation Δf, and also evaluates whether large or small between the Δf and a constant α. As the Δf which is less than the α in normal travelling, becomes greater than the α when the stopper of an engine mount 20 touches an engine 11 due to sudden starting-off or acceleration, the frequency variation evaluation section converts the pulse signal before transmitting it to an adaptive filter, in which the amplitude and phase compensation are performed on the signal using a filter coefficient A×W which is smaller than an adaptive filter coefficient W used until then. This attenuates the output of a controlled system 48 and weakens the vibration force required to remove an external face.

Abstract: PURPOSE:To automatize resistivity control by starting the processing of a numerical control program concerned with machining process after the value of resistivity given from the resistivity detecting device for machining liquid attains the value of basic resistivity stored in a memory. CONSTITUTION:Machining liquid 21 filtered by a resistivity control device 10 is agitated before starting discharge machining, and the value of the resistivity is processed to be target resistivity. CPU 7 detects the value of the resistivity using a sensor 18 attached to the resistivity control device 10 to control the filtered machining liquid 21, and reads the value of the resistivity of the present filtered machining liquid 21 through a resistivity detecting device 9, and compares the same value of the resistivity with the value of the resistivity stored in a memory 1.

Abstract: PURPOSE:To ensure call connection between a subscriber of a radio relay station and a subscriber of a low order terminal station by providing a fault detector and a dummy master station equipment to the radio relay station and switching and connecting an output signal of the dummy master station equipment to a multiplexer upon detection of fault occurrence. CONSTITUTION:When a communications fault takes place on a multiplexer transmission line with either a base station or a relay host station or a transmitter-receiver 700, a fault detector 702 detects it and gives a switching command to a transmission line changeover device 701 to switch a signal connection path toward the transmitter- receiver 700 direction to the direction of a dummy master station equipment 703. The call connection communication among telephone subscribers 706, 707 and telephone subscribers of a low order terminal station or a relay station is attained by the changeover. The dummy master station equipment 703 has a subscriber exchange and a function of a base station and executes exchange connection processing such as call processing, called party number reception analysis processing and incoming call processing, and time division multiplex communication processing. Thus, even when a fault takes place on a transmission line or a transmission bag on the way, the communication with low order stations is secured.

Title: Concentrated control device for air conditioner
Inventor: FUJIEDA HIROSHI
IPC: F24F11/02
Filed: 1979-01-12
Abstract: PURPOSE: To make it easy to confirm a non-electricity-applied state in units inside and outside a chamber by a method wherein a microcomputer mounted in a concentrated control panel, an indication control means comprising a driver and an indicating means of the concentrated control panel are employed.  
     CONSTITUTION: When a unit 2A inside a chamber is made to operate by turning on the switch 3A 1  of a concentrated control panel 3 when the unit 2A inside the chamber is in a non-electricity-applied state, a datum on the fact that the unit 2A inside the chamber is in a non-electricity-applied state is sent to the concentrated control panel 3. A microcomputer 33 outputs a signal which turns a LED3A on and off, and the LED3A is turned on and off. This state of turning on and off is changed into that of lighting up if the unit 2A inside the chamber is turned into an electricity-applied state by changing the unit 2A into the electricity-applied state. If a unit 1 outside the chamber is in the non-electricity-applied state, the microcomputer 33 outputs a signal which turns on and off the LED3C, and the LED3C is thus turned on  and off.

Title: Noise reduction system
Inventor: KUMAKURA TATSURO
IPC: G05B19/414
Filed: 1994-01-18
Abstract: PURPOSE:To provide a noise reduction system capable of relatively reducing the level of the noise mixed into a transmission line in comparison with the level of an output signal. CONSTITUTION:A 1st gain magnification setting means 12 sets the transmission gain magnification at a proper level where the signal receives no influence of the peripheral noises on a transmission line 30. A transmission control means 13 amplifies the output signal received from an output signal generating circuit 11 up to the multiple value as much as the set transmission gain magnification and outputs an amplified signal. A 2nd gain magnification setting means 21 sets a reciprocal of the gain magnification set by the means 12 as the reception gain magnification. A reception signal control means 22 reduces the amplified output signal received via the line 30 down to the multiple value as less as the set reception gain magnification and outputs a reduced signal. In such a constitution, the output signal which is amplified by the means 13 is reset at its original level.
