Title: Method for preventing malfunction by mis-connection of cable
Inventor: KAGAWA YOSHIMASA
IPC: G01R31/04
Filed: 1982-09-10
Abstract: PURPOSE:To detect the opening and closing of loops and to prevent the malfunction of connected apparatus by using respectively plural connection wires with respect to plural cables as check signal wires for preventing mis-connection and forming the loop wherein the check signal wires are closed when the cables are correctly connected. CONSTITUTION:When a cable 3 is substd. with a cable 4, a loop is formed as the cables are of the same specifications. On the other hand, if the connection of the cable 3 on the apparatus 12 side is connected erroneously to the juncture where the cable 4 is connected, the circuit extended through the check signal wire 31 from the pin P31 of a connector CN31 is connected to the jack J41 of a connector CN42 and since said circuit is connected to neither thereof thereafter, no loops are formed. Similarly, when the cables are mis-connected, no loop circuits are formed in either cases. Since both terminals of the loop are connected to the input terminal of a detection circuit 6, whether the connection state of the cables is normal or not is known when the circuit 6 detects the electrical conduction between the two wires connected to the input terminals thereof.

Title: Read-only memory device
Inventor: KAWAGUCHI HIDEJI
IPC: G11C17/00
Filed: 1990-06-15
Abstract: PURPOSE:To restrain the rise of the source potential of a reading memory cell and to stabilize access time while reducing the deterioration of the capacity of electric current by setting residual electric charge other than selected bit lines free at all times. CONSTITUTION:A bit line BL2 becomes a certain prescribed electric potential V1 when a memory cell 22 is read out. Here, an 'n' channel transistor (Mnp) 41 for a current bypass connected to a bit line BL 1 is turned on because it is gate-controlled by a -CL 1 which is the inversion signal of a column selection CL 1, and the residual electric charge on the bit line BL 1 is set free. Further, Mnp 42 and Mnp 43, connected to the non-selection bit line similarly at the time of the reading of the memory cells 21 and 22, are turned on when memory cells 23 and 24 are read out to set the residual electric charge of the bit lines BL2 and BL3 free. Thus, the rise of the source potential of the reading memory cell can be restrained and the delay of the access time can be prevented.

Title: Automatic frequency controller
Inventor: TAKAHASHI MASAO
IPC: H03J7/02
Filed: 1981-10-01
Abstract: PURPOSE:To keep the best reception state even with a small reception input, by sampling DC output of a frequency discriminator and controlling a local oscillation frequency when the value is of the same polarity consecutively for a prescribed number of times. CONSTITUTION:When a reception input 1 is decreased and the S/N is deteriorated, a DC output A of a frequency discriminator 6 is fluctuated due to fluctuated noise, and the polarity of one or more signals out of (n) signals from a sampling circuit 10 is inverted and it is detected at a polarity discrimination circuit 11, then a sample holding circuit 12 is not revised and the local oscillation frequency is unchanged. With the good S/N, since the polarity is not inverted for even one signal out of the (n) signals of the sampling circuit 10, the local oscillation frequency is changed. Thus, the local oscillation frequency is not uselessly controlled at the deterioration of the S/N, allowing to obtain an automatic frequency controller suitable for a narrow band communication.

Abstract: PURPOSE:To preferentially display a fault having higher seriousness by replacing a currently displayed fault with the fault having the higher seriousness than that of the currently displayed fault and displaying the fault having the higher seriousness when a fault seriousness comparing means decides that the fault having the higher seriousness than that of the currently displayed fault exists. CONSTITUTION:A fault seriousness comparing means 3 compares a fault seriousness 13 to indicate the seriousness of the fault currently displayed on the fault message display area of a CRT and a seriousness 26 of another fault under an occurring state. A decision 4 is for deciding the result of the fault seriousness comparing means 3, and when A<B, a priority display means 5 is executed.
