    摘要: An optical pickup emits a light beam onto a recording medium and outputs, in response to a reflection from the medium, a first and a second signal for controlling focusing servo control and tracking servo control, respectively. A signal generating section generates a focus error signal and a tracking error signal in response to the first and second signals, respectively. A driving section is responsive to the output of the signal generating section for outputting a first and a second drive current assigned to focusing and tracking, respectively. An actuator moves the pickup in a focusing direction and a tracking direction by the first and second drive currents, respectively. An adjusting section detects two values close to the maximum and minimum values of the tracking error signal at the start of the focusing servo control and adjusts the gain of the second signal on the basis of a difference between the detected values. Alternatively, the offset of the second signal may be adjusted by the sum of the two detected values. Further, the offset of the first signal may be adjusted by a focus offset occurring when the amplitude of the first and second signals appearing after the start of the focusing servo control or the amplitude of a third signal also outputted by the pickup and representative of recorded data and appearing after the start of tracking servo is close to the maximum.

    摘要: A looped data transmission system has a pair of looped transmission lines forming two transmission systems having different transmission directions, and a plurality of stations including at least one control station connected to said transmission lines of the two transmission systems. If a fault occurs in the two transmission lines of the two transmission systems in the same section, a loopback configuration is established such that stations adjacent to the faulty section send signals from one system back to the other system. With the loopback configuration being established, the stations which have received supervisory signals sent from a loopback end station send them back to the transmission line of the other system. When one of the loopback end stations has received a supervisory signal from the direction of the faulty section, it is judged that a portion of the faulty section is recovered, and the result of the judgement is communicated to the control station.

    摘要: A method for producing a seasoning from whey is disclosed wherein lactic acid bacteria are inoculated into whey and cultured at a temperature of 30.degree.-50.degree. C. while adjusting the pH to from 6-7. The fermented solution is centrifuged to produce a precipitate phase which contains proteins and a supernatant phase which contains alkali salts of lactic acid. The proteins are decomposed with a mineral acid or a proteolytic enzyme to produce a Seasoning Liquid A. The supernatant phase is neutralized and concentrated to produce a Seasoning Liquid B, and admixed with Seasoning Liquid A.

    摘要: A loop type data transmission system based on a token pass principle, wherein a station whose transmission of data is completed passes therethrough a token to the stations located downstream. The station demanding the transmission acquires the right of transmission when received the token, to perform data transmission with a given station. The token signal is classified into a free token representative of the freedom of the line and a busy token representative of occupation of the line. Among a plurality of stations, only one station is destined to execute detection of transmission failure and remedy thereof. This one station is adapted to convert the free token detected upon reconstitution and repeating of the received information into the busy signal and subsequently re-send the free token. The station having sent out the free token after the completed data transmission is transferred to the state for reconstituting and repeating the received information when the busy token returns to that station.
