Title: Recording of information signal and recording method and apparatus
Inventor: TOOMASU KUROODO HENRII KIIN
IPC: G11B20/02
Filed: 1988-07-12
Abstract: PURPOSE: To prevent superior restoration recording of information signals by composing recording from information signals and spoiler signals, and providing the spoiler signals with a frequency modulated to synchronize with a changing frequency-modulated signal. CONSTITUTION: IC1 works as a signal envelope shaping unit by means of peripherally integrated resistance R, capacity C and transistor TR1 , shaping a waveform by a variable resistance VR3 , and deciding cutting time on the TR1 disk. IC1 imparts a low frequency waveform to the pin 1 of IC2 . IC2 functions as a high frequency generator, imparting an output of a free running multivibrator to a pin 9, performing frequency modulation by R11 , R12 , shaping a waveform by VR5 , and generating a spoiler signal. The frequency-modulated signal is made a sweep frequency variation actuating between 300-600Hz or changed by clearly defined binarization. With this composition, a superior reproduced recording of information signals is prevented by the spoiler from the carrier wave type recording such as video.

Title: Picture quality adjustment circuit
Inventor: SAKAGUCHI TAKASHI
IPC: H04N5/208
Filed: 1991-07-12
Abstract: PURPOSE:To obtain a picture quality adjustment circuit which has a simple configulation and produces no error of timing for generating the asymmetrical secondary differential signals. CONSTITUTION:A buffer circuit 11 receives the secondary differential signal of a luminance signal and then outputs it after the amplification or the input/ output impedance conversion. A clip circuit 12 clips the secondary differential signal and outputs it. A signal inverting circuit 13 inverts the secondary differential signal and outputs it. A synthetic resistance 14 adds together the output signal of the circuit 11 and the output signal of the circuit 12 in a ratio of 1:(1-K) where 0<=K<=1 is defined. Meanwhile, a synthetic resistance 15 adds together the output signal of the resistance 14 and the output signal of the circuit 13 in a ratio of 1:(1-L) where 0<=L<=1 is defined. Thus the asymmetrical secondary differential signals are obtained. An adder 16 adds the asymmetrical differential signals to the luminance signal.

Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To raise sensing performance by comparing the frequency of a Colpitts oscillator using a magnetic impedance element with the frequency of a reference- signal oscillator which has been corrected for external electromagnetic wave noise. SOLUTION: A magnetic impedance element 1 is connected between the collector and the base of transistor Tr. Due to impedance variation of magnetic impedance element 1, the oscillation frequency of Colpitts oscillator 8 varies. By counting this oscillation frequency, external magnetic field can be measured. The frequency of the Colpitts oscillator 8 and the frequency of a reference signal oscillator 6 are compared with a frequency comparator 7. From the variation of the frequency, the variation of external magnetic field can be exactly read. In order to eliminate unnecessary electromagnetic wave noise, an antenna for detecting the electromagnetic noise or a hollow coil is assembled in the reference signal oscillator 6, which corrects the output of the reference signal oscillator 6.

Abstract: PURPOSE:To enable analysis while preventing the hindrance of the progression of reaction and the degradation in measurement accuracy by bringing a valve into tight contact with apertures so that an air pressure regulator pressurizes or reduces the pressure in a reaction cuvette to discharge the liquid remaining in a siphon tube or doing others while the reaction cuvette remains static. CONSTITUTION:The suction of a reactive liquid sucked into the siphon tube 44 is executed while the reaction cuvette 4 exists in a set position 37 of an instrument 38 for expelling the liquid in the siphon tube 44 to be exclusively used for suction. More specifically, a solenoid of the instrument 38 is driven with respect to the reaction cuvette held static in the position 37 so that the valve part closes hermetically the apertures 42, 43 of the reaction cuvette and a throttle valve is simultaneously actuated to communicate with the inside of the air reservoir in which the pressure is reduced by a vacuum pump. The pressure in the reaction cuvette is thereby reduced and the reactive liquid in the siphon tube 44 is sucked and admitted into the reaction cuvette 4. The cleaning water from a cleaning water dispenser 25 is dispensed into the reaction cuvette upon ending of the final measurement and the high-speed operation is made for the specified time. The reactive liquid is discharged together with the water from the siphon tube 44 during this time.
