Abstract: PURPOSE:To detect a paper jam of continuous paper and cut paper before completion of paper passing, in a copying machine and the like, by constituting a device such that an arrival detecting means-anival required time-setting timer, arrival detecting means and passing detecting means of the papers generate outputs to perform a decision of arrival and passing of the papers. CONSTITUTION:Output of a paper selector switch 11a is input to a central processing unit (CPU)43. A paper feed roller, not shown in the drawing, is driven to convey the first sheet of paper through a driver 11b and feed clutch 11c selected on the basis of a paper feed signal S7 of the first sheet. With the lapse of prescribed time after the paper feed roller is driven, a timer setting signal S4 is input to a counter 36, after counting of the setting time, a point end detecting signal S5 is input to the CPU43. While output of an arrival switch 25 has been input to the CPU43, and output S3 of a passing detecting means 21 is decided by an AND gate 40, then its decision, that is, a passing abnormal signal S6 is input or not, thus the CPU43 decides presence of a paper jam. In this way, the paper jam can be decided before completion of passing.

Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To restrain generation of hillocks as much as possible, by forming an electrode layer on an underlying layer via a buffer layer made of a metal part oxide. SOLUTION: A multilayer structure 1 constitutes a capacitor of a ferroelectric non-volatile memory. On an underlying layer 2 of silicon oxide or the like, a lower electrode layer 4 is formed via a buffer layer 3 made of a metal part oxide. On the lower electrode layer 4, a ferroelectric layer 5 and an upper electrode layer 6 are sequentially stacked. Thus, generation of hillocks in the electrode layer in annealing in an oxygen gas atmosphere may be restrained. Also, reduction in capacitance of the capacitor may be restrained as much as possible, thus enabling formation of a capacitor having less unevenness.

Filed: 1984-08-22
Abstract: PURPOSE:To prevent processing of supervision interruption response from being retarded by detecting the state of operation environment (utilization factor) of a processing unit in an information processing system and changing the time interval of interruption from a supervisory device depending on its result. CONSTITUTION:The supervisory device 31 of a constitution controller 30 applies supervisory interruption to processors 10, 20 at each designated time interval and when the supervisory response devices 11, 21 of the processors 10, 20 generate supervisory response based on drive environment information of each processor in receiving the interruption. The information is the state of load (utilization factor) of the processor 10 or 20 and the response is generated by changing the timer value in response to the quantity of the utilization factor. The timer value by the response is utilized as the supervisory time value until the constitution controller 30 obtains the response to the supervisory interruption. If lots of processings in precedence over the supervision interruption processing are generated, the timer value is set largely and the processing of the supervision response is not delayed.
