IPC: H04N7/16
Filed: 1995-01-06
Abstract: PURPOSE: To surely deliver emergency contact information to any area by extracting and displaying character information from a received medium wave. CONSTITUTION: A reception circuit 10 applies amplification and video demodulation processing to a radio wave such as television radio wave received by an antenna A to provide an image signal. A character information extract circuit 11 extracts a telop signal relating to a character included in the image signal.

Title: Clock multiplication circuit and semiconductor integrated circuit
Inventor: HIRANO KATSUSHI
IPC: H03K5/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To generate a highly precise clock waveform by generating a pulse waveform by using either a rise waveform or the fall waveform in two clock signals outputted from a delay line circuit. SOLUTION: Signals D1-D3 with an equal delay time difference are taken out from an external clock inputted to the delay line circuit 10. The external clock and the signal D1 are inputted to an R S flip flop 21 and the pulse waveform E1 whose period is set to be an 'L' level is generated with the difference of delay time from the rise of the external clock to the rise of the signal D1. The signals D2 and D3 are inputted to an R S flip flop 22 and a pulse waveform E2 is similarly generated. The signals of the pulses E1 and E2 are synthesized in a HAND circuit 30 and a two-fold clock is obtained. Since the waveforms E1 and E2 in the part of the difference of delay time are generated by using only the rise of the waveforms of the external clock signal and the signals D1-D3, the difference does not occur in the pulse width of the waveforms E1 and E2.

Abstract: PURPOSE:To regenerate a radiation image appropriate for an observing read shadow by removing an image signal in an unphotographed section in case of reading out an image signal from a dividedly photographed radiation image and determining an image processing condition. CONSTITUTION:A radiation image photographing part 20 photographs an object 101 and accumulatively records radiation image information, a reading part 30 for book reading converts the recorded information into a digitized image signal and an image reproducing part 40 reproduces a radiation image from the image signal. In case of executing divided photographing in said constitution,, the processing is executed as follows. Namely, an unphotographed area recognizing circuit 317 inputs divided photographing information Sd and outputs an unphotographed area indicating signal St indicating an unphotographed section. A signal extracting circuit 314 removes an image in the area of the signal St from an image signal Sp and sends the residual signal Sp' to a control circuit 315 to determine the gradation processing condition. An image signal obtained as the result is regenerated by a reproducing part 40 to obtain a radiation image appropriate for an observing read shadow.

Filed: 1990-01-26
Abstract: PURPOSE:To improve a power factor by controlling a lag quantity so that the lag quantity coincides with the phase advance quantity of a reactive power compensation device in a period of the reactive power of a load does not occur. CONSTITUTION:Current signals from a lag current detection CT 20 and a phase advance current detection CT 21 are inputted to a lag Q detector 22 and a phase advance Q detector 23 with a voltage signal from PT 5 connected to a high voltage bus 3 and an reactive power signal is detected. The negative value Qref of a phase advance reactive power signal Q3 and the averaging 24 value of a lag reactive power signal +Q2 are operated in an adder 25 and an output from the adder 25 is inputted to a controller 26. Then, the output signal is inputted to a negative signal cut circuit 27 and the output signal is inputted to an adder 17 with the output signal Qsvc of a Q detector 6. At that time, the signal from the circuit 27 is outputted only when lag reactive power is large. When the reactive power detection value of the load 4 is '0', only the signal from the circuit 27 is inputted to the adder 17 and thyristors 13 and 14 make the operating current small. Then, the lag quantity is reduced and it approaches a phase advance current.

Abstract: PURPOSE:To discriminate whether a radio wave does not exist at a point because of a shadow of a radio wave or out of tracing of a radio wave due to vibration or the like with an inexpensive device by providing a planer antenna section, a down-converter and a BPF. CONSTITUTION:A planer antenna section 1 consists of one element in array elements and a 12GHz radio wave received by the antenna section 1 is converted into a 1GHz band radio wave by a down-converter 2. Then the signal is converted into a 2nd intermediate frequency (402.78MHz) via a frequency mixer 3 and a local oscillator 4 and converted into a frequency at which a BPF 6 is usable by a converter 5. Then the converted frequency is, subject to band limit through the BPF 6 at 170kHz or below, undesired noise component is eliminated and only the signal component is extracted, amplified by an amplifier 7, detected by a detector 8 and the presence of a signal is detected. Thus, whether an object is in a shadow of a radio wave where no radio wave exists or out of tracing of the radio wave due to vibration or the like is discriminated with an inexpensive device.
