Patent KR-830002782-B1 (KR)
IPC: H04L25/03
Filed: 1980-09-13
Granted: 1983-12-14
Abstract: The submission makes use of the fact that where an adaptive equaliser (APS) is incorporated in a modem, some sort of training sequence is employed prior to the transmission of the data message. This training sequence usually incorporates a block of pseudo-random data (DIS) transmitted at the basic symbol rate to provide the equaliser (APS) with a relatively less distorted signal to operate on. During the training period both threshold-derived timing (TCTRL) and Nyquist-derived timing (NTRL) are produced. The Nyquist-derived timing (NTRL) is then phase-shifted (APS) to correspond to the threshold derived timing (TCTRL) which is valid during the training period. The phase shift (APS) is then fixed so that, when multi-level coding is introduced valid timing can still be obtained from the Nyquist-derived timing signal (NTRL). In addition in the event of transmission interruptions the invention allows timing recovery without the need for a new training cycle.

Title: Screw and nut mechant for controlling a nuclear reactor
Inventor: DESFONTAINS GUY
IPC: G21C7/14
Filed: 1981-02-17
Granted: 1984-12-29
Abstract: The invention relates to a screw-and-nut mechanism for controlling a nuclear reactor by displacement of neutron absorber units in the core of the reactor. One of the elements (screw or nut) is rotated by means of a drive member connected to the shaft of a motor. The drive member includes a profiled portion of the element movable in rotation to fasten these parts in rotation while leaving them free to move in translation. A grab retains the screw-nut mechanism in a fixed vertical position on displacements of the absorber unit and allows the unit to fall back for emergency shut-off. For release of the grab and raising of the cover of the tank of the reactor, it is possible to separate the screwnut mechanism completely from its housing and from the cover of the tank.

Title: Process for producing grain-oriented electro-magnetic steel sheet
Inventor: NOZAWA TADAO
IPC: C21D9/52
Filed: 1981-06-04
Granted: 1985-09-14
Abstract: In the secondary recrystallization of a grain-oriented silicon steel sheet, a specific temperature gradient is generated thereby developing secondary recrystallized grains having a good (110)[001  orientation and increasing the magnetic flux density higher than that previously obtained. The temperature gradient is established at the boundary region between the primary and secondary recrystallized regions, with the result that highly oriented (110)[001  secondary recrystallization nuclei preferentially are caused to develop.
