Title: Skew preventive unit of vtr
Inventor: AZUMA NOBUO
IPC: G11B20/02
Filed: 1979-07-11
Abstract: PURPOSE:To prevent the skew from occurring even when the variable-speed magnifying rate of VTR whose H matching between adjacent tracks in recording is not done, by delaying a reproduced signal by a fixed time every time when its dropout  appears. CONSTITUTION:As two rotary heads differing in azimuth perform variable-speed reproduction, dropout (d) appears at reproduced envelope (c). At the point in time when dropout (d) appears, and excessive horizontal period of 2alphaH (alphaH; the number of shifts between adjacent tracks) is added to reproduced signal (b). For the purpose, every time when dropout signal (d) rises, reproduced video signal (b) and  video signal (f) delayed by ¦2alphaH-H¦ time (H; horizontal synchronizing signal  period) are changed alternately to obtain a video signal, so that the video signal has  an excessive horizontal period of 2alphaH+¦2alphaH-H¦. Here, ¦2alphaETA-H¦ corresponds to a  skew value, holding the continuation of H.

Title: Data correcting circuit
Inventor: TANIGAWA YUJI
IPC: G06F7/76
Filed: 1988-04-08
Abstract: PURPOSE:To reduce the scale of circuits by swapping upper and lower bits of data, which should be subjected to correction of digit movement, on demand and right or left shifting data once by the number of required bits and swapping high-order and low-order bits. CONSTITUTION:A data selector 3 swaps high-order bits and low-order bits of the output of an input data register 1 when the value in a shift control register 2 indicates the left shift direction, but the selector 3 selects the output value of the input data register 1 when it indicates the right shift direction. The output is right or left shifted once by the number of required bits, and high-order bits and low-order bits are swapped again. Thus, the processing of digit movement correction is executed without requiring a selecting circuit of the bit width of digit movement for the purpose of preventing bit losses at the time of digit movement correction.

Title: Fault monitoring system for multiporcessor system
Inventor: SOMEYA KAZUNARI
IPC: H04L69/40
Filed: 1991-03-27
Abstract: PURPOSE:To evade the discontinuation of the fault monitor processing given to each communication control module in a multiprocessor system where a system monitor module and plural communication control mudules are connected to a system bus. CONSTITUTION:The monitoring priority is previously set to the communication control modules 14 and 15. The module 14 having the higher priority decides the fault of a system monitor module 13 when the fault monitor informing signal is not received yet from the module 13. Then the fault monitor informing signals are continuously transmitted to the module 15 until the fault of the module 13 is recovered. Thus the module 14 performs the fault monitor processing in place of the module 13. If the module 14 executing the fault monitor processing in place of the module 13 has a fault, the module 15 having the next higher priority performs the fault monitor processing in a system.
