Title: Wrong output preventing method for digital controller
Inventor: INOUE YOSHINORI
IPC: G05B9/02
Filed: 1988-09-08
Abstract: PURPOSE:To prevent the wrong output which is produced when a programmable logic controller PLC is restarted by forcibly keeping the control output in an OFF state for a fixed time of the initial working in the case the abnormality is recovered and an output action is restarted. CONSTITUTION:When a PLC10 detects the abnormality via a self-diagnosing part 26, an R-S flip-flop 70 of a wrong output preventing circuit 60 is reset by the input signal received from the part 26. Thus the circuit 60 controls a contact 44 in an OFF state with the output of the flip-flop 70. The signal to be inputted to an AND element 68 is kept in its previous state for a fixed time by a timer element 66 even though the input signal received from the part 26 is changed at restart after the abnormality is recovered. Therefore no reset input is applied to the flip-flop 70 even with push of a resetting switch 62. Thus the contact 44 is kept OFF. As a result, the wrong output is never produced even with the incomplete recovery of the abnormality.

Title: Field effect transistor
Inventor: KURITA NORIAKI
IPC: H01L29/812
Filed: 1989-08-30
Abstract: PURPOSE:To reduce the source resistance and to improve gm to reduce generation of noises by forming an active layer which is thinned as it gets near a drain electrode from a source electrode and by forming it by at least one layer of a shallow N-type layer and a deep P-type layer, respectively. CONSTITUTION:The thickness of an ion implantation N<->-layer 4 is formed thin gradually from a source 5 to a drain 6 to reduce the source resistance and to improve the gate withstand voltage. As for a method to increase sharpness of a carrier concentration profile and to improve gm, a P-layer 7 is formed in parallel below the N<->-layer 4 to compensate for the electrons near the N<->- layer to substrate interface with a P-layer. Thereby, a channel is thick at the side of a source electrode and thin at the side of a drain electrode. Since a carrier concentration profile is sharp, the source resistance lowers while the gate withstand voltage increases, thereby improving gm in comparison with a conventional FET.

When the operation lever is operated under such condition, the other hydraulic actuator can be operated. That is, by selecting and switching one hydraulic actuator and the other hydraulic actuator, operation can be effected using one of a pair of left, right operation levers and hence another operation lever is not needed.
