Title: Semiconductor device
Inventor: KINOSHITA YOSHITAKA
IPC: H01L27/04
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To discharge the charge on the gate side of an output MOSFET and to prevent ESD destruction by providing a P channel or N channel MOSFET for protection between a source or drain and an external terminal. SOLUTION: When the gates of N channel MOSFET N3 and N4 for protection, namely, an internal node ne is turned to a positive high potential by device charging, the potential at their sources, namely, at a data output terminal Dout is lowered by discharging accompanying conductor contact so that these MOSFET are turned into on-state. Thus, charges stored at internal nodes na and nb are discharged through these MOSFET N3 and N4 and turned into low potential. As a result, corresponding to the positive high potential caused by device discharging, the inter-gate/source voltage of an output MOSFET N1. and the inter-gate/drain voltage of an output MOSFET N2 are reduced, its oxide film destruction is prevented and the reliability of a large scale integrated circuit device LSI can be improved.

Title: Packet switching system
Inventor: KOSAKA TOMOMI
IPC: G06F11/20
Filed: 1990-05-30
Abstract: PURPOSE:To restart a call during communication on the occurrence of a fault by allowing a control system to sweep out packets under processing at present prior to the system changeover due to the occurrence of a fault. CONSTITUTION:When a fault takes place in a control system comprising of a system bus controller 4 and a communication control processor 6 during communication control, the system bus controller 4 stops the reception of a data packet from a system bus 2 and sends remaining data packets in the system in the transmission direction. Simultaneously, a line controller 8 stops the reception of a data packet from a line 3 and sends remaining data packet in the system in the transmission direction. The communication control processor 6 confirming the end of transmission of the remaining data packets starts a system bus controller 5 and a communication control processor 7 forming a succeeding control system to take over the control of a succeeding communication control module 1. Thus, the communication is restarted.

Title: Position detection of endless belt-shaped photosensitive body
Inventor: TAKAHASHI IZUMI
IPC: G03G15/00
Filed: 1984-07-10
Abstract: PURPOSE:To set accurately the home position of a photosensitive belt by forming two holes on the photosensitive belt at a prescribed interval and inputting detection signals of these holes to discriminate them in accordance with preliminarily set conditions. CONSTITUTION:Two holes 5a and 5b are provided at a certain interval on the side face of a belt 3 near a connection part 4. When detection signals of the connection part 4, holes 5a and 5b, and a crack 6 are inputted to a control circuit 10, pulses Ta and Tb for detection are outputted each time and are held for a certain period, and they are processed as an effective signal only when the following detection signal is inputted in this certain period. Consequently, pulses Ta and Tb due to detection of the connection part 4 are made ineffective because pulses due to detection of the following hole 5a are outputted during the duration of pulses Ta and Tb due to detection of the connection part 4, and only pulses due to detection of the hole 5b are processed as an effective signal by coincidence of the input timing of the signal. Thus, the home position of the belt is set accurately.
