Title: Sheet transport sensing device
Inventor: KITANI YUKITOSHI
IPC: B65H7/02
Filed: 1982-10-06
Abstract: PURPOSE:To have accurate sensing of the transport of sheets with a simple mechanism by reading the identification mark of that one of the sheets loaded in a copying machine, which lies in a specific position counted from the uppermost lying one, and by judging the leading edge of this specific sheet with a transport sensor by means of the counted value by a timer until said edge is sensed by a post-sensing identification sensor. CONSTITUTION:If a transport sensor S1 senses the leading edge of a specific one of the sheets loaded and is turned on, a timer 14 is reset to commence counting, and when the counted value attains a value corresponding to the reference time, the output of the identification sensor S2 is read and entered at this timing. It is judged that sheet treatment is carried out in the intended processes and order and that the transport speed is normal, if the identification sensor S2 senses the hole 7 at this timing. If on the other hand this check timing does not give sensing of the hole 7 by S2, it is judged that either double feed has occurred or that the transport is carried out at an abnormal speed, and an error signal will be emitted. Eventual interruption of sheet transport does not influence ill, because an inclint of the timer 14 is stopped at the same time as the transport clutch signal 9 is turned off. Thus accurate sensing is assured.

Inventor: ARIMOTO MASAO
IPC: H01L21/76
Filed: 1987-07-13
Abstract: PURPOSE:To prevent two or more islands whose potential difference differs largely from being coupled with one another by a method wherein an electric current flowing into a first parasitic transistor is absorbed by a second parasitic transistor in order to prevent an operation of the first parasitic transistor which takes part in an operation of a device. CONSTITUTION:A third, island 6 is formed in an isolation region 4 between a first island and a second island 1, 2 which are adjacent to each other. An electric current flowing into a first parasitic transistor 5 with a low current- amplification factor generated between the first island and the second island 1, 2 is absorbed by a second parasitic transistor 7 with a high-current amplification factor generated between the island whose potential is higher out of the first island and the second island 1, 2 and the third island 6; an operation of the first parasitic transistor 5 is obstructed. By this setup, even when an island whose potential may become lower than that of a substrate 3 or another island with a considerably high potential is installed, it is possible to prevent the electric current from flowing between the islands and to prevent the islands from being coupled with each other thanks to the parasitic transistor.
