IPC: B65H85/00
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To make both sides copy of N parts from the document of a circulated one side by carrying out the process in which an even-numbered document is copied to an unused paper and stored in an intermediate tray and the process in which an odd-numbered document is copied to the back surface of an one side copied paper and discharged alternately at every one time, when a first cycle detection trouble is judged. SOLUTION: When for example, two both sides copy is made from six pieces of one side document, in the first cycle of the document, the even numbered page of the supply document D in a document storage 2 is transfered to one side of a record paper P fed by a cassette 106 and stored to an intermediate tray 113. In the second cycle of the document D, an odd numbered page is transfered to one side of the record paper P fed by the cassette 106 and the even numbered page is transfered to the other side of the record paper P fed by the intermediate tray 113 and one side transfered record paper P is stored in the intermediate tray 113 and both sides transfered record paper is discharged to a discharge tray 110.  In the third cycle of the document D, the odd numbered page is transfered to the other side of the supply record paper of the intermediate tray 113 and discharged to the discharge tray 110. When the motion of the first cycle detection lever LV1 can not be detected by a sensor, the first cycle and third cycle are repeated alternately and both sides copy can be obtained from the one side document regardless of the first turn detection.

Title: Microcomputer
Inventor: WATANABE HIROSHI
IPC: G06F11/00
Filed: 1984-07-04
Abstract: PURPOSE:To detect an accurate temperature on the surface of a microcomputer chip by providing a temperature sensor and an A/D converter on said chip. CONSTITUTION:The voltage level of the output of a temperature sensor 2' is supplied to an A/D converter 2, and the output of the converter 2 is stored to a register 3 for result of conversion. The contents of the register 3 are shifted to an accumulator through an internal bus 4. Then the data corresponding to the surface temperature of a microcomputer chip can be read out within a temperature range less than the reference voltage which is supplied from an input terminal 5. If said temperature exceeds the reference voltage of an output terminal 5 of the sensor 2', the register 3 has overflow. Then the register 3 sets an overflow flag 6 for result of conversion and also delivers an abnormal temperature rise interruption request signal 7. A CPU uses this interruption request signal to execute the interruption processing. Thus the surface temperature of the microcomputer chip can be easily suppressed within a rated range.
