Title: Servo data checking method for disk device
Inventor: SASAKI TOSHIHARU
IPC: G11B21/10
Filed: 1988-07-06
Abstract: PURPOSE:To prevent a read error due to erroneous erasing, etc., by positioning a head to a track, to which servo data are recorded, after that, adding prescribed position off-set, detecting whether the reading output of these servo data shows a value to correspond to the off-set or not and judging the abnormality of the servo data. CONSTITUTION:A head 2 is positioned to the track, to which the servo data are recorded, and after that, the prescribed position off-set is given. Then, it is detected whether the servo data reading output in such a condition shows the value to correspond to the off-set or not. When a detected result is judged as the abnormality, such a condition is judged as the abnormality of the servo data. When the servo data are checked, it is preferable that complete on-track is executed at the time of servo data normality for the position of the head 2 before the off-set is given. Thus, the destruction of the data with the erroneous position correction of the head, which is caused by the erroneous erasing of the servo data or unrecording, etc., and read error can be prevented.

Title: Bit arrangement system in program signal codec
Inventor: MATSUMOTO YOSHIAKI
IPC: H04J3/00
Filed: 1989-06-30
Abstract: PURPOSE:To avoid the data of each channel from being '0' without degrading the transmission characteristic by adopting bit arrangement for a PCM signal in a way that '1' exists more than one in the channel of each 8-bit corresponding to a telephone channel. CONSTITUTION:The positions of Z, E, X, Y are replaced into those of C, G, D, P. Since the X, Y, Z are included in CHa+1, CHa+2, '1' exits in them without fail. Moreover, since the parity bit P is decided so that the sum of '1s' in S, X, Y, Z, A, B, C, D, P is an even number, '1' exists more than one in the CHa without fail. Thus, it is prevented that all bits of each channel are '0'.

Abstract: PURPOSE:To make it possible to load an exchange to be tested in a complete in-use state, by providing this exchange with a master pseudo-call device transmitting and receiving control information and an increased pseudo-call device providing call holding. CONSTITUTION:When master pseudo-call device 1 is actuated via console panel 107, controller 105 starts operation and informs control circuit 305 of increased pseudo-call device 3 of the actuation.

Then, circuit 105 exercises control over the confirmation of a dial tone and, when knowing that an answer train is connected securely, sends a train holding indication to circuit 305. Thus, circuit 305 operates the relay of circuit 301 to change this originating train over to a holding train and starts counting the call holding time assigned to this train. Next, circuit 105 enters into train recovery operation the holding time later and releases this train.
