Title: Automatic tuning system for probe in nmr device etc.
Inventor: KOSAKU TOMIO
IPC: G01R33/36
Filed: 1992-01-31
Abstract: PURPOSE:To prevent the tuning sensitivity of a tunable probe in an NMR device or an NQR device from being lowered by high harmonic waves in high frequency waves applied to the probe. CONSTITUTION:In a turning system for a nuclear magnetic resonance device, in which high frequency waves at an observed frequency are inputted to a terminal A of a tunable probe 5 by way of a directive coupler 4, and a signal reflected at the terminal A is picked through the directive coupler 4 so as to tune the probe 5 in order to minimize the degree of the reflected signal, if the high frequency waves contain high harmonic waves at the observed frequency, switches 13 to 15 are turned to the terminal b side. The high frequency waves is inputted to a terminal B of the probe 5, bypassing the directive coupler 4, and a signal passing through the probe 5 is taken out from another terminal A thereof. Accordingly, the probe 5 is turned so as to maximize the passing signal.

Title: Photographic resin-coated paper
Inventor: ASAO KOUJI
IPC: D21H19/38
Filed: 1979-02-15
Abstract: PURPOSE:To obtain photographic resin-coated paper having high print image resolving power by covering titanium oxide with a surfactant and adding the covered titanium oxide to polyolefin for coating.

Title: Fast detector for switching condition
Inventor: MATSUDA TAKASHI
IPC: G01R31/00
Filed: 1990-01-26
Abstract: PURPOSE:To shorten a processing time for detection of a key operation without awaiting the completion of a discharge in an input signal line by performing a fast discharging of a charge on the input signal line at a timing before the application of a voltage pulse to an output signal line. CONSTITUTION:For example, only when a key switch 1 alone is turned ON, a CPU 7' makes a discharge voltage DIS high during a high period at all of output terminals KO1-3. During the period, an FET8 is turned ON and a charge stored in a capacitance 6 is discharged fast. Therefore, the CPU 7' can load input voltage immediately after the terminals KO1-KO3 go to low so that time per cycle can be shortened for the detection of a key operation. A resistance value of a resistor 5 becomes a large value while the terminals KO-KO3 are low. This can minimize the number of signal lines as a whole thereby achieving a higher processing efficiency and a reduction in the size of circuits with a less number of pins as densified in an LSI.

Filed: 1979-02-15
Abstract: PURPOSE: To make a vacuum column needless to start and stop a tape well by constituting the system so that the tape may be decelerated as it is when an inter block gap is detected in a prescribed speed section.  
     CONSTITUTION: In case that an error is detected in data block D, the driving signal is cut off at point P 1 , and magnetic tape 7 stops at point P 2 . Counter 17 counts tachometer pulses to record the distance between points P 1  and P 2 . Next, tape 7 is caused to run reversely, and magnetic tape control unit 16 reads out data block D and cuts off the driving signal when an inter block gap is detected. Point P 4  indicates the inter block gap detection point. As the result, the magnetic tape stops at point P 5 ; and when the magnetic tape runs forward again to reach point P 6 , contents of counter 17 become zero and re-read of data block D is performed, thus making good tape starting and stopping possible.

Filed: 1987-01-26
Abstract: PURPOSE:To manufacture a MOS transistor with an LDD structure which has an excellent hot electron resistant property with a substantially simplified manufacturing method by applying ion implantation to source and drain regions twice with different implantation angles and different concentrations. CONSTITUTION:After an element isolation region is formed on a single crystal silicon substrate 1, a gate oxide film 2 is formed on an element region.

Title: Remote supervisory and control system
Inventor: OKAMOTO ATSUSHI
IPC: H04Q9/00
Filed: 1992-01-31
Abstract: PURPOSE:To improves the receiving states of distant control parts and parts to be controlled by outputting currents to two-wire transmission lines while switching output voltage levels when a power supply part detects currents returned from the plural control parts and parts to be controlled which are connected through the two-wire transmission lines. CONSTITUTION:The power supply part impresses the positive side of the DC voltage of a capacitor C1 rectifying an AC power source 21 by a diode bridge DB 1 to the collector of a transistor(Tr) Q1 and impresses the negative side to the emitter of a Tr Q2. When the currents returned from the plural control parts and parts to be controlled are detected through the two-wire transmission lines connected to a (+) input terminal and the emitter of the Tr Q1, the Tr Q2 is turned on by a comparator 22. Therefore, according to the existence of returned currents, the level of an output voltage to the transmission line is decreased to the opposite direction drop voltage of a Zener diode ZD 1 or increased to the original voltage. Namely, voltage change width is extended even when the transmission line is long and the voltage is decreased by the resistance of the line. Thus, the receiving states of distant control parts and parts to be controlled are improved.

IPC: H01S3/13
Filed: 1995-02-03
Abstract: PURPOSE: To make possible the generating on of an alarm by accurately detecting an overcurrent owing to the deterioration of a laser when the setting temperature of a laser is changed. CONSTITUTION: A detected temperature signal of a laser and a laser driving current value signal are inputted in an overcurrent alarm generating circuit 700. The detected temperature signal is weighted with a weighting device 701, added to a threshold level for alarm to a reference temperature of the laser which is previously set, with an adder 702, and outputted to an overcurrent detecting circuit 703, as a threshold level for an alarm which corresponds to a detected temperature. The overcurrent detecting circuit 703 compares the laser driving current value signal with the threshold level for alarm and outputs an overcurrent alarm signal when the laser driving current value signal exceeds the threshold level for an alarm. Thereby the deterioration of the laser is accurately detected.
