Title: Clock switching system for duplex data processor
Inventor: IGI YOUZOU
IPC: G06F1/04
Filed: 1980-03-28
Abstract: PURPOSE:To prevent the destruction of data, by making switching after waiting for the end of one operation under way in the main storage device, when the switching of system is made from one to another due to the production of error. CONSTITUTION:In the data processor 0 system in use, the operation like prescribed write-in, readout and rewrite-in is made with the instruction from CPU1 by the main storage device 2. If an error takes place to the device 2 due to any cause during data processing, and the read out data cannot be guaranteed, the emergent detection signal is delivered from the emergency operating device 4 to the emergency operating device 4' of the waiting 0 system. Further, when the main storage device 2' does not make read in and write-in, the device 4' controls the switching circuit 5' and supplies the clock CLKO from the clock source 6 of the 0 system to CPU1' to read out required data. When the device 2' reads in or writes in, switching is made after waiting for the end of one operation under way.

Title: Automatic train controller
Inventor: TANAKA MITSUHIKO
IPC: G05B23/02
Filed: 1979-04-06
Abstract: PURPOSE:To surely perform resetting, by using a time element circuit formed at the time of closing of application of electric power to an ATC unit to assure time large enough to reset a trouble detection relay. CONSTITUTION:When power is applied, a relay KR is operated and a resetting  relay RSR for trouble detection relays is energized. As a result, the trouble detection relays CHR1-CHR3 are energized. At the same time, power is supplied to speed collation units 1-3 as well and an ATC unit starts prescribed operation. The time of resetting by the resetting relay is determined by the time constant of the time element circuit of a time relay TLR. For this reason, the time constant is set at a value much larger than the contact action time of the relays CHR1-CHR3. The value is larger than operation starting preparation time in the application of the power and is not smaller than such a value that the establishment of the initial condition of a relay contact circuit is ensured. The results in surely effecting the resetting.
