Title: Multiplex concentrator
Inventor: MOTOHASHI TOMOO
IPC: H04L5/22
Filed: 1982-05-10
Abstract: PURPOSE:To detect the failure of reception and to attain the speed switching of a high-speed MODEM automatically, by starting a timer when synchronism is broken after the establishment of the synchronism, resetting the timer at the establishment of the synchronism, and detecting the time-out of the timer. CONSTITUTION:In high-speed reception sections 22, 22' of a TDM, the time is set to a valve, and counting is started when the state changes from ''concentra- tion'' into'' detection of synchronizing character'', the counting is stopped at the ''concentration'' and reset. When the counting reaches a value, the state is designated as the failure of reception, and the speed switching of a high speed MODEM3 is performed. The TDM2 detecting the failure of reception changes the pattern of the synchronizing character and transmits a frame. The timer is started, the reception state is brought to the character detection 24 to stop the reception. When a TDM2' receives this pattern three times in succession, an SDS is set on to a high speed MODEM3' to reduce the speed, the reception state is brought to the operation 24 and the reception is stopped. When the timer reaches the time-out, the TDM2 sets on the SDS and decreases the speed.

Title: Electric car controller
Inventor: UENISHI KOICHI
IPC: H02P7/298
Filed: 1990-03-28
Abstract: PURPOSE:To enhance workability by decreasing the conduction ratio of a cargo chopper only when the deviation between the position of a memory and the position of a cargo lift is smaller than a setpoint and lift ascent speed exceeds a reference speed so as to stop the cargo chopper at the position of a selected memory. CONSTITUTION:Selecting a memory address by a memory address input circuit 13 allows a counter value at an automatic stop position to be registered in the memory address. When the difference between a counter value indicating lift height and a data value of automatic stop height is less and more than values each set arbitrary, a lift ascent speed is compared with the value which is a several-fold multiplication of a cargo chopper command 22: if the lift ascent speed is larger, the cargo chopper command 22 is decreased. When the data difference becomes less than a setpoint, a microcomputer 1 makes the smallest value of cargo command the conduction ratio of a cargo chopper, so that the cargo chopper 5 stops to automatically stop the lift at a stop position of the memory address.
