Filed: 1989-01-11
Abstract: PURPOSE:To perform a calculating processing with high speed and to reduce an arithmetic error in amplitude value when a frequency is varied by providing a squaring device, fixed number multiplying device and adding device. CONSTITUTION:Seven sampling values are inputted and the 1st through 7th sampling values are squared respectively by the squaring device 11 which is provided with squaring units in parallel, and also the squared values of the 2nd and 6th sampling values are multiplied by 6 and the squared values of the 3rd and 5th sampling values are multiplied by 15. Further, the squared value of the 4th sampling value is multiplied by 20, then the total added value is obtained by adding (13) the 1st through 7th sampling values. Next, the total added valued is divided (14) by 32 and calculated to obtain the square root (15), then the amplitude value of an AC electric quantity is outputted. The arithmetic result can be thus obtained with high speed, and at the same time the calculation can be made with high accuracy even when the frequency is varied. Performance of a digital protective relay or a controlling device can be drastically improved accordingly.

Title: Pyroelectric type contactless infrared-ray thermometer
Inventor: FUKADA TAKAFUMI
IPC: G01J5/62
Filed: 1985-01-11
Abstract: PURPOSE:To measure temperature contactlessly with high accuracy and reliability by chopping off only infrared rays radiated from a substance to be measured precisely within the visual field of an infrared-ray sensor and forming a horn. CONSTITUTION:The horn 10 has an infrared-ray passage 13 for penetrating infrared-rays 12 radiated from the substance 11 to be measured and forms a chopper passage 15 into which a chopper 14 can be rotatably inserted from the side part on its center part. The pyroelectric type infrared-ray sensor 18 is built in an infrared-ray discharge port part of the passage 13 to prevent the horn from the incidence of infrared rays radiated from an area other than the substance 11 to be measured. While rotating, the chopper 14 chops off the infrared rays 12 at a notched part 17 to supply an intermittent infrared-ray signal to the sensor 18. A signal processor 19 processes the supplied signal together with signals outputted from a photointerrupter 20 and a temperature detector 21 to correct the phase and the room temperature and a linearizer converts the signal into a voltage signal proportional to the temperature of the substance 11 and outputs the voltage signal to a display part.

Title: Interface circuit for character/pattern display unit
Inventor: KOMATSU SHIGERU
IPC: G06F3/14
Filed: 1979-01-17
Abstract: PURPOSE: To prevent the display of the insignificant patterns by inhibiting the video signals for the reset preparatory period during which the power supply is made and the CPU executes the program.  
     CONSTITUTION: The data of display RAM8 are read out in sequence based on the addresses produced through synchronous signal/display address generation circuit 6 and then supplied to character generator 9. Then the character code which means the supplied data is converted within generator 9 into the parallel data corresponding to the character pattern, and the parallel data is drawn in when the S/L terminal of shift register 24 in parallel-serial conversion circuit 10 features "L" and then delivered through output terminal 25 for the period of "H" and via the rise of the clock entering the CK terminal. Here, when clear terminal 28 features "L", the output data becomes "L" regardless of the input data. Thus the display can be avoided for the insignificant patterns by inhibiting the video signals for the reset preparatory period during which the reset signal gives the power supply make and then the CPU executes the program.

Abstract: PURPOSE:To reduce the hunting of the temperature of feed hot water and improve the durability of burners by detecting the state of feed hot water and the state of stopping the hot water feeding by means of a water flow sensor and appropriately setting the period of combustion and fire extinguishment of burners in accordance with respective states. CONSTITUTION:During hot water feeding, the flow of water from a feed water source to a heat exchanger 1 is detected by a water flow sensor S, and a control substrate 9 receives a signal I from the water flow sensor S to discriminate a feed hot water state. In accordance with the times of respective states, the quantity of gas to respective burners 5a and 6b is determined. For example, in a case where the burner 5a of a small capacity has been selected, when a required thermal load is less than a predetermined combustion quantity, the burner 5a is burnt and fire-extinguished in a period in accordance with the feed hot water state, and hot water heated to a predetermined temperature is fed to a hot water feed apparatus 3. At the time of stopping the hot water feed, the burner 5a is burnt and fire-extinguished, and is maintained at a predetermined temperature up to the time of reusing the hot water. When the required thermal load in more than a predetermined combustion quantity, the burner 5a is continuously burnt and the temperature of feed hot water is maintained at a predetermined temperature.

Title: Magnetic recording and reproducing circuit
Inventor: KOSHIMOTO YASUHIRO
IPC: G11B5/02
Filed: 1985-01-14
Abstract: PURPOSE:To shape the reproduction waveform of a signal detected by a thin- film head with high recording and reproducing efficiency and to facilitate the processing and identification of the signal by attenuating the output signal of a differentiation circuit and the output of the 2nd delay means by a specific level respectively and adding them to the output signal of the 1st delay means. CONSTITUTION:The ratio of the peak value of the main pulse Pm of a signal S24a and peak values of subordinate pulses Pa and Pc is 2-4, so the attenuation factors K of attenuators 29 and 31 are set to about 1/2-1/4 and then adjusted to remove the subordinate pulses, thereby obtaining a playback signal similar to a Lorentz waveform obtained by lengthwise recording and reproduction. Attenuated pulses of subordinate pulses contained in the signals 25a and S25c are superposed newly upon a reproduced signal S33 and although the waveform is not the complete Lorentz waveform, the subordinate pulses which are attenuated and superposed decrease in peak value to 1/K<2> and is extremely small, so there is almost no problem. Consequently, the processing and identification of a signal using the thin-film head with high recording and reproducing efficiency are facilitated.
