Title: Fault detection system of information processing system
Inventor: ITOU SHINICHI
IPC: G06F11/00
Filed: 1978-12-31
Abstract: PURPOSE: To detect immediately the fault occurrence of a control circuit as to buffer memory BFM by providing a flag bit to each group of data stored in BFM, and then by supervising the flag bit by a central controller.  
     CONSTITUTION: Sense matrix SMX is read and right before data are stored in buffer memory BMF, flag bit FB is set to "1" at the initial address of write data W- DT. When FB of data R-DT read out from central controller (CC) is "1", it is considered to be correct data and a read process is advanced. Then, this FB is reset to "0" by reset circuit RS. Since the read period of CC is shorter than the write period  of BFM, "1" can be read from FB all the time as far as a control circuit for BFM is normal. If this control circuit gets out of order, BF has a part where no data are periodically written and may become "0" in data read operation. In this case, error detection circuit ED provides fault detection.

Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To more efficiently filter a transition signal by providing an association clamp means for limiting undesired signal transmission between a first filter port and a second filter port and limiting the fluctuation of the desired parameter of a signal. SOLUTION: A line filter constitution LP is placed between a first filter port LO and a second filter port LI. A line terminal LIa is connected to the first terminal part of a coil L1, and the second terminal part of the coil L1 is connected to a local terminal LOa through the main path of a first FET transistor T1. The line terminal LIa is connected to a gate (g) of the transistor T1. When voltage is increased in the filter port LI, a current 1 increases. The main path resistance of the transistor T1 also increases, and the current I is reduced. Thus, fluctuation dI/dt of the current I is immediately limited to a prescribed value.
