Disclosed are terbium-activated oxide phosphors having incorporated, at least one of ytterbium, thulium, samarium and europium. Incorporation of the element (s) has made it possible to produce phosphors exhibiting high brightness and suffering little brightness deterioration under high-density electron bombardment.
摘要:
A thermal-optical converter which comprises an aqueous solution containing a non-ionic compound with a functional group, a closed vessel for containing the solution and a transparent window fitted to at least one part of the closed vessel which allows the solution to be visible. Because the aqueous solution is transparent at low temperatures and opaque at elevated temperatures, the thermal-optical converter can effect reversible optical changes in accordance with changes in the temperature of the solution.

It is an object to provide signal processing device and method by use of wireless communication, which is capable of analyzing status of the wireless communication in detail at a later date, compressing a wireless signal such that it can be reproduced, and reproducing the compressed signal to perform its re-reception. The signal processing device includes a reception processing unit that performs reception processing of a received signal wirelessly, a signal recording unit that records the signal, a signal compression unit that compresses an information amount of the received signal, and a signal output unit that stores the received signal that has been compressed or outputs the same to an external device. The signal compression unit divides a signal, obtained by frequency-transforming the wireless received signal, into a signal portion large in amplitude value and a non-signal portion small in amplitude value on a frequency spectrum, calculates a representative value based on a feature quantity of the non-signal portion and combines the signal portion and the representative value into a compressed signal.

In a touch panel, a rectangular resistive film is formed on a substrate and electrodes are provided along the four sides of the resistive film. Each electrode includes a plurality of gaps and a plurality of divided electrodes. The divided electrodes are linearly arranged along the corresponding side of the resistive film, and the electrode, in which the divided electrodes at both ends are connected to terminals, respectively, is formed by arranging the divided electrodes of the same shape and repeating this same shape.
摘要:
A current regulator has a current regulating semiconductor device and a microcontroller which outputs a PWM pulse for driving a load to the current regulating semiconductor device and receives outputs of a high-side current detection circuit and a low-side current detection circuit from the current regulating semiconductor device. An output mixer of the current regulating semiconductor device switches, in synchronization with the PWM pulse, between the output of the high-side current detection circuit and the output of the low-side current detection circuit on one signal line to output the output to the microcontroller.
摘要:
When executing sequential processing such as a ladder logic, converting a program formed of an instruction set of another processor to a program executable by an own processor in software and then conducting processing lowers the real time property. In a control system, a storage unit stores a program for the own processor and a program for another processor. A processor reads data from the storage unit, executes processing described as a program, and gives an instruction to change over a method for acquiring data from the storage unit, to a conversion instruction unit according to data contents. A changeover unit is connected to the storage unit directly or via the conversion unit to change over the data acquiring method according to an instruction from the conversion instruction unit. The conversion unit converts data read from the storage unit to data executable by the processor, according to a conversion scheme.
摘要:
A processing unit is connected to another processing unit through a system bus composed of serial signal communication line and synchronization signal communication line to be able to communicate therewith. When an operation unit detects abnormal state in the processing unit, the operation unit supplies notification of detection of the abnormal state to synchronization unit. The synchronization unit transmits the received detection notification of abnormal state to the other processing unit through the synchronization signal communication line. Conversion unit receives parallel communication data from the operation unit through important signal line instead of general signal line and converts the received parallel signal into serial signal to be transmitted to the other processing unit through the serial signal communication line, thereby soundness among processing units connected to the system bus is ensured when the system bus is configured to attain serial communication.
