Filed: 1985-03-25
Abstract: PURPOSE:To suppress a leakage current from a transfer corotron and to perform excellent transfer even to a form which has a high water content by holding part of a corotron shield which contacts the form at a constant potential. CONSTITUTION:The form 11 is moved as shown by an arrow 12 and discharged to the left side in a figure while contacting the reverse surface of a photosensitive drum 2.

IPC: H01L27/10
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device wherein a plurality of transistors different in gate oxide film thickness from one another are integrated into one chip without degrading transistor characteristics. SOLUTION: A plurality of external terminals (output terminals) on a semiconductor substrate where a plurality of two or more transistors different in gate oxide film thickness from one another, are connected with an internal circuit through an interface circuit. Transistors other than the transistor having the thinnest gate oxide film are used for the transistors P7, N7 connected directly to the external terminal. A thick-film gate oxide film transistor is used for a node in contact with an external power supply and requiring a high withstand voltage, and a thin-film gate oxide film transistor is used for a transistor not in contact with any external power supply, as mentioned above.  Since only voltages that can be controlled by internal voltage drop is applied to the thin- film gate oxide film transistor as a result, the degree of freedom in device/ circuit designing is significantly enhanced.

Filed: 1990-03-09
Abstract: PURPOSE:To improve the isolation characteristic with a low loss by forming a dielectric board onto one major side of a ferrimagnetic base and providing a ground electrode between transducers formed on the dielectric base at a prescribed interval. CONSTITUTION:When a DC magnetic field is applied in a direction orthogonal to a major plane of, e.g. a YIG thin film 12 and an input signal is given to one transducer 18, a volume forward travelling magnetostatic wave (MSFVW) is excited in the YIG thin film 12. Then the magnetostatic wave is received by other transducer 20, from which a signal is outputted. Then a dielectric base 16 is formed among YIG thin films 12, 18 and 20. As a result, the coupling among the YIG thin films 12, 18 and 20 is strengthened and the insertion loss is reduced. Moreover, since a ground electrode 22 is formed between the films 18 and 20, the coupling between the films 18 and 29 in terms of an electromagnetic field is loosened and the isolation characteristic between the input and output is improved.

Title: Receiving circuit for switch closing signal
Inventor: SETO FUMIAKI
IPC: G06F3/02
Filed: 1980-05-02
Abstract: PURPOSE:To prevent chattering with simple circuit constitution by providing one piece of counter for generating carrier pulses which is kept reset during the period when chattering is occuring, commonly to all the switch circuits in a receiving circuit used for receiving switch closing signals. CONSTITUTION:When one of switches SW0-SW15 is pushed and the counting of a counter CNT1 reaches the depressed switch number, a multiplexer MPX put outs an output to an output terminal T1, thereby allowing a counter CNT2 to start counting. Whereas, during the chattering period, the input from the depressed switch to MPX repeats 0 1 0 ... and therefore the output terminal T1 stops outputting immediately. If the period from the start of counting of the counter CNT2 until carry pulse generation is made longer than the chattering period, the carry pulse is outputted after ending of the chattering and a central control unit CC receives this and reads out the depressed switch number stored by CNT1 into the register REG. Hence, the chattering of all the switches is prevented by one chattering preventing circuit.
