摘要： Mechanical vibration of a rotating test body is translated into a periodic signal which represents a combined vector of the unbalance means of the rotating body and the mechanism that rotates it. The periodic signal is divided into two orthogonal vector components. The magnitude of the two vector components are converted into digital signals and applied to a computer. Unknown values of four constants are determined by a preliminary test having three successive stages. In the first and second stages the test body is rotated to register the digital signals; in the second state the angular position of the test body is displaced a predetermined amount with respect to its first stage position. In the third stage of the test, a trial dead weight of a known mass is mounted on the test body and rotated to register the digital signals. The computer operates on the registered digital signals to determine the four constants in accordance with a set of equations. After the preliminary test, the data registered in the first stage of the preliminary test is substituted into another set of equations using the four constants to determine the dynamic unblance mass and its angular location.

摘要： An RF signal is read from a rewritable DVD while rotating the rewritable DVD. The read RF signal is converted to pulse signals according to different threshold values, and the number of pulses of each pulse signal is counted. Indexes IBSmin, IBMmax, IBS, and IBRmax are determined from the relationship between the counted numbers and the threshold values, and the recording quality of the BCA on the rewritable DVD is evaluated by judging whether these indexes satisfy the following inequalities: IBMmax/IBSmin≦0.8 IBRmax/IBS≦1.5

摘要： A velocity signal is obtained by calculating both the selected signal of the differentiated signal of the position signal from a position detector and the selected signal of the sinusoidal wave signal according to position displacement, so that a velocity detection produces a smaller velocity detection error at a low velocity and generates no ripple component even when a high velocity is detected.

摘要： When an input data of a slave station makes any change, the slave station transmit a serial information (in serial data frame, FIG. 2) which is made by altering an information continuously transmitted from a master station into a serial information to be transmitted by interrupt, which serial information includes a start information (in start bit), interrupt information (in interrupt field), address information (in address field) of this slave station and data information (in data field) produced in this sub-station responding the change, and it is transmitted by the interrupt; therefore the master station can find the interrupt-transmitted serial information among many serial informations sent back thereto, and the slave station can immediately transmit the change to the master station without wasting time by waiting for one turn scanning of all the slave stations.

摘要： In a data transfer apparatus, as one substation in a loop type signal transfer system, e.g. for use in an automatic machine, synchronization information and address information are received and the address is checked by an address coincidence circuit; when address coincidence is detected the data information in the received signal is replaced by serialized data which is contrived by parallel-serial conversion of the parallel input data at the substation; therefore there is no need of once storing the entire received signal transferred, and therefore, high speed data transfer results.
