Title: Photothermal measuring cell
Inventor: DAGURASU MATSUKUIIN
IPC: G01N21/59
Filed: 1981-10-09
Abstract: A photothermal measurement cell for study of light absorption by a sample substance. The sample substance is placed in contact with a temperature expansion element (6) of a solid material, for example quartz, glass, sapphire or the equivalent. The said element is arranged in contact with a mechanoelectric or mechanooptical transducer (7), for example a piezoelectric crystal. As the light is absorbed by the sample substance its temperature is raised, whereupon the temperature expansion element (6) expands and its mechanical motion is transformed to an electric signal by the transducer (7), whereupon the signal is amplified and registered for example by an X-Y recorder (10).
Patent JP-H0936681-A (JP)
Title: Power amplifier
Inventor: HIGASHIYAMA KATSUHIKO
IPC: H03G3/30
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To prevent a power transistor(TR) from being damaged owing to overheating by detecting the temperature of the power TR by a temperature control system and controlling switching between high voltage power and low voltage power. SOLUTION: Power line 10 and 14 can selectively supply the high voltage power and low voltage power. The output of a level detector 7 (11) is connected to the base of the power TR 8 (12). The level detector 7 (11) generates a high- level signal when detecting a peak audio signal being larger than a reference voltage. Then the power TR 8 (12) turns on to supply high voltage power +VH(-VH) to the power line 10 (14). When the level detector 7 (11) detects the peak audio signal being smaller than the reference voltage, on the other hand, the level detector 7 (11) generates a low-level signal. Then the power TR 8 (12) turns off to supply the low-voltage power +VL(-VL) to the power line 10 (14).

IPC: G11B7/258
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To easily perform focus servo and tracking servo and to improve the S/N of reproducing signals and recording density by forming a semitransparent reflection layer showing super resolution effect in the irradiation side of a mask layer which gives a super resolution effect on the irradiated side of a signal recording part and recording or reproducing by irradiation with light. SOLUTION: The optical recording medium 1 is produced by forming a semitransparent reflection layer 3 which is extremely thin and which gives a super resolution effect on a light-transmitting substrate 2 and forming a mask layer 4 having a super resolution effect thereon. Further, a recording layer 5, reflection layer 6, protective layer 7 are successively formed as a recording part on the mask layer 4, then guide grooves 8 are formed, and the surface of the light-transmitting substrate 2 where no layer is formed is irradiated with light. Therefore, the recording density is further improved by the double super resolution effect, as well as the intensity of detection light is properly increased. Therefore, even when the mask layer 4 is formed, focus servo or tracking servo is easily performed, and the S/N ratio of the reproducing signals is increased.

IPC: H04N1/40
Filed: 1986-07-08
Abstract: PURPOSE:To correct an image signal two-dimensionally by comparing the quantity of the total number of black picture elements in a peripheral picture element group based on a noted picture element and in the noted picture element with a preset reference by a correction circuit and correcting the noted picture element to the black picture elememt if the total number of the black picture elements is larger than the reference value and correcting the noted picture element to the white picture elements if the total number is smaller than the reference value. CONSTITUTION:An adder circuit 2 counts black picture element numbers represented by logical 1 included in 9 picture elements supplied simultaneously and gives a count value ADDAT to a comaprator circuit 3. A reference value SD is set to the comarator circuit 3 from a reference value setting circuit 4 and the comparator circuit 3 compares the reference value SD with the count value ADDAT. When the count value ADDAT is larger as the result of comparison, logical 1 (black level) is outputted as a picture element color of the noted picture element, and logical '0' (white level) is outputted, when smaller, and a signal of a logical value in compliance with the picture element color of the noted picture element is outputted when both are equal. Thus, a correction picture signal PIX, whose isolated picture element color is corrected is outputted from the comparator circuit 3.

Filed: 1979-12-12
Abstract: PURPOSE:To prevent the deterioration of sound quality by eliminating the need for phase modulation by adding an audio intermediate frequency including an out- of-phase modulated component, by providing an audio intermediate frequency generating circuit with a circuit that inverts and mixes only an audio carrier. CONSTITUTION:An audio and video carrier passed through tuner 1, trap 2 and VIF amplifier 3 are passed through mixer 4 to generate an audio intermediate frequency of 4.5MHz. However, the audio carrier is also passed through phase shifter 5  providing 180 deg. delay to generate an audio intermediate frequency of 4.5MHz by mixer 6 and the audio intermediate frequency are mixed with it. This composite audio intermeidate frequency is FM-detected. Consequently, the composite vector of the composite vector generated by the video carrier and audio carrier and that generated by inverting only the audio carrier is positioned on the extension line of a video carrier vector at any time and even if the video carrier vector to be amplitude- modulated varies, the composite vector never entails a phase modulation loss. Therefore, audio detection free from sound quality deterioration can be performed.
