Title: Binary coding circuit
Inventor: KODERA MASAHIDE
IPC: H03K5/08
Filed: 1983-08-10
Abstract: PURPOSE:To obtain an accurate image both in bold line parts and fine line parts of a picture by synthesizing signals of reference voltage or more obtained from picture signals and effective signals even if lower than reference voltage and processing said signals. CONSTITUTION:A picture signal 3 is supplied to a comparator circuit 1, a white ground area setting circuit 6 and a peak value detecting circuit 10. The circuit 1 compares a fixed reference voltage 2 and the signal 3 and outputs a binary picture signal 4. The circuit 6 compares a fixed reference voltage 7 which is lower than the voltage 2 and the singal 3, and outputs a binary signal 8. The circuit 10 detects an effective signal 15 of voltage 2 or less from signals 3, 4, 8. The signals 4 and 15 are added in an OR circuit 5 and a signal 16 is obtained. A threshold value processing circuit 9 converts the signal 16 to a signal 18 which is continuous in the picture area by using the signal 8. By detecting effective signal disappearing under the voltage 2 only, an image of fine line parts becomes accurate.

Title: Digital multi-frequency signal receiver
Inventor: FUJII KENSAKU
IPC: H04Q1/457
Filed: 1978-11-25
Abstract: PURPOSE:To prevent an unavailable time slot from being generated, by providing a discrete Fourier conversion operation unit for every detection frequency. CONSTITUTION:Since frequencies used for multi-frequency signals and continuity test signals are 700, 900, 1100, 1300, 1500 and 1700Hz, discrete Fourier conversion operation circuits 11-16 are provided for respective frequencies. Output values from circuits 11-16 are transferred to one decision circuit 20' to decide presence or absence of signals. Thus, the time slot of each discrete Fourier operation circuit is always available, and unavailable time slots are eliminated, and each discrete  Fourier conversion operation circuit operates without distinguishing multi-frequency  signals and continuity test signals from each other. Consequently, change in hardware is not required even if combination of the number of lines for multi-frequency  signals and the number of lines for continuity test signals is changed.

Abstract: PURPOSE:To reduce the cost and to facilitate the PLL design by sharing the main part of a PLL frequency synthesizer, used by one receiver, in the plural number of receivers. CONSTITUTION:When PLL enters the phase-locked state through the channel- selecting operation of the 1st receiver, a tuning voltage obtained by the channel  selection is stored in digital memory 36 via A/D converter 35.

IPC: B65G33/24
Filed: 1979-11-12
Abstract: PURPOSE: To prevent grains from damages due to unexpected accidents by providing sensors in at least two positions of a discharge tube of a spring conveyer for transferring grains or the like to adjust transferring speed according to the operational condition of the sensors.  
     CONSTITUTION: A spring 9 of a spring conveyer rotated by a prime mover 15 transfers grains or the like in a transferring tube 1 and supplies them from an expanded terminal portion 3 through a discharge tube 13 to a hopper 41 and others. When the discharge tube 13 is clogged with grains, the lower sensor 37 detects the clogging and is turned on to decelerate the prime mover 15. When the upper sensor 39 also is turned on, the prime mover 15 is stopped. When the sensor is turned off, the transfer of the spring conveyer is resumed. Thus, whenever the discharge tube of the spring conveyer is clogged with grains or the like, the spring conveyer is immediately stopped to prevent the grains from damage.

Inventor: SATOU KENICHI
IPC: C21B5/00
Filed: 1979-11-09
Abstract: PURPOSE:To eliminate the risk such as blowing-out of contents in the furnace or gas explosion in the furnace after banking of the blast furnace by preliminarily sucking external air immediately before the banking of the blast furnace and naturally sucking the external air after the banking of the furnace. CONSTITUTION:Immediately before the end of the reducing blowing-out operation of the blast furnace 8, a blow-off valve 1 is entirely opened to enable external air to be sucked and introduced. Thereafter, after banking of the furnace, from the blow off valve 1 through a blast piping such as a main blast pipe 2 and a branch pipe 4, a natural draught into the furnace 8 is performed. Thus, even immediately after the banking, required amount of oxygen is ensured, carbon monoxide or hydrogen is not detected but an adequate natural combustion in furnace can be carried out. Therefore, a safety banking of furnace having no risk such as the blowing-out of contents of the blast furnace or the gas explosion is performed.

Abstract: PURPOSE:To save power consumption and to accelerate the rising of room temperature by controlling the opening of a water quantity regulating valve for controlling the quantity of cooling water to be fed to an outdoor water heat exchanger corresponding to the operating rotating speeds of a compressor and an indoor fan. CONSTITUTION:When the fact that a room temperature detected by a sensor 18 arrives at the vicinity of a set room temperature during the cooling/heating operation of an air conditioner is detected by a controller 19, the rotating speeds of a compressor 11 and an indoor fan 15 are reduced to a predetermined values in response to the temperature difference thereby to decrease the circulating flow rate of refrigerant of a refrigerating cycle and heat exchanging amount of an indoor air heat exchanger 16. Simultaneously, the opening of a water quantity regulating valve 20 is reduced to a predetermined opening by the controller 19, the flow rate of the cooling water to an outdoor water heat exchanger 13 is reduced, thereby saving driving power of a cooling water circulating pump. On the other hand, when the large temperature difference is detected by the controller 19 at the time of start, the compressor 11, the fan 15 and the valve 20 are operated with high capacity to accelerate the rising of the room temperature.

Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a precise signal detector where its circuit configuration is simplified in the detection of real component I and an imaginary component Q of a complex signal and I and Q components with the same phase can be obtained and to enhance the performance of an ultrasonic wave diagnostic device using the signal detector. SOLUTION: The signal detector acquires samples of a received signal at each timing tn deviated from the phase of its carrier by π/4 and a multiple of an odd number m of π/2. A cosine code operation section 174 applies code operation to each sampling value S(tn)=I(tn)cosθ(tn)-Q(tn)sinθ(tn) outputted from a data rate conversion section 170 where a sign of a coefficient of the I(tn) is made constant. Thus, that is, the Q(tn) has a coefficient whose sign is inverted for each m π/2. That is, the term with respect to the Q(tn) is a vibration term. The I(tn) can be acquired by filtering out the vibration term with an LPF 184. On the other hand, a sine code operation section 176 applies an operation to the same S(tn) to bring the I(tn) into the vibration term and an LPF 194 outputs the Q(tn) at the same phase with that of the I(tn).
