Title: Back-up control method for fault information
Inventor: SHIMIZU TAKEMASA
IPC: G06F11/34
Filed: 1985-07-03
Abstract: PURPOSE:To utilize a stored fault information to the analysis of the fault factor by writing the fault information onto the recording medium of the external memory device of its own connection when a connection bus has the abnormality. CONSTITUTION:The fault information stored in the fault storing buffer 61 of an external storage controller 6 is transferred to a main memory MEM 2 via a connection bus 5 by an instruction given from a CPU 1. Here if the abnormality of the bus 5 is detected, the device 6 writes successively the fault information on the buffer 61 to the fault information storing area in the recording medium 41 of an external memory device 4. A pilot lamp 62 is turned on when said storage is completed. Thus an operator confirms the abnormality of the bus 5 and damps the volume of the fault information storing area for the medium 41 with another system. This enables the reuse of the fault information as the data when the fault factor is analyzed.

Title: Surface potential detector for charged material and static eliminator using its detector
Inventor: YAMAMOTO YOSHINORI
IPC: G01R29/12
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a sensor with a wider surface potential detection range of a charged material. SOLUTION: In the condition that high voltage is supplied from a high voltage power supply 5 to a sensor 2, an output signal corresponding to an electric line of force proportional to the magnitude of a surface potential from a charged material 1 opposed thereto is obtained. The output signal is input through an amplifier 3 to a control circuit 4 to find a value for the surface potential of the charged material. The output voltage of the high voltage power supply 5 is detected by a voltage detection circuit 6 and, when it is outside a range of a power voltage, a switching circuit 7 is operated by a signal from the control circuit to prevent the voltage of the high voltage power supply from being applied to the sensor. In such a state, the output signal obtained by the sensor is defined as a value for the surface potential of the charged material.

Title: Method and device for sharing terminal of ic
Inventor: ENDO SHINJI
IPC: H01L27/04
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To make one terminal usable in common to fetch input data and output output data. SOLUTION: While an operation start circuit 11 inhibits the output data from being outputted through the common terminal 13 when a reset signal 1h is in a reset state, a buffer 2 outputs to a latch 12 the input data which are temporarily stored from a gate circuit 21 through the common terminal 13. The latch 12 receives the input data through the common terminal 13. When the reset signal 1h is brought into a unreset state, the latch 12 latches the input data and the buffer 2 does not supply the input data which are outputted from the gate circuit 21 and temporarily stored through the common terminal 13, but discharges them from another place. The operation start circuit 11, on the other hand, outputs the output data through the common terminal 13 when there are the output data once the reset signal 1h is brought into the unreset state.

Title: Pll circuit
Inventor: NAKAJIMA YOSHIBUMI
IPC: H03L7/08
Filed: 1983-08-09
Abstract: PURPOSE:To eliminate adverse effect to be exerted onto a post-stage circuit by turning off the output signal of a PLL circuit when no input signal is fed to a phase comparator. CONSTITUTION:The phase comparator 1 compares a 1/n frequency division signal of an input signal with a 1/m frequency division signal of a voltage controlled oscillator 3 in phase and outputs an error voltage l in response to the phase difference. This output voltage l is smoothed by a low pass filter 2 and goes to a control voltage (c) of the voltage controlled oscillator 3. As a result, an output frequency of the voltage controlled oscillator 3 is synchronized with the input signal frequency. When the input signal level to the PLL circuit is judged as normal by a level detector 6, an output switch 7 is turned on and the output of the voltage controlled oscillator is fed to the circuit of the next stage but when the result is judged as abnormal because the input signal level is zero or very low, the output switch 7 is turned off and no output of the voltage controlled oscillator 3 is transmitted to the next stage circuit.
