Title: Cross-under resistance circuit
Inventor: FUJII TOSHIAKI
IPC: H01L27/04
Filed: 1986-01-29
Abstract: PURPOSE:To decrease the parasitic capacitance in wirings, by forming a resistor with an N<+> impurity region, forming a layer, which isolates the resistor, with a P-well, thereby reducing the junction area between the resistor and the layer for isolating the resistor, and reducing the junction capacitance. CONSTITUTION:An N<+> impurity region 9, which is formed in a P<-> impurity region P-well 8 in N-epi 3, forms a cross under resistor. A P<+> impurity region 10 surrounds the N<+> impurity region in the surface direction of a substrate and removes the effects of a parasitic FET transistor. At the same time the contact resistance between an Al layer 74 and the P-well 8 is decreased. An N<+> region 11 is provided for reducing the contact resistance between the Al layer 74 and the N-epi 3. An N<+> embedded layer 12 is provided in order to reduce the resistance in an island surrounded by the N-epi 3. The N-epi 3 is connected to the highest potential in an integrated circuit. The P-well 8 is connected to the lowest potential. The P-N junction between the P-well 8 and the cross under resistor 9 is reversely biased for any signal. The signal passes only through the region 9, and a part between the cross under resistors is electrically insulated.

Filed: 1979-02-16
Abstract: PURPOSE:To form picture elements and make it possible to correct picture images by providing one n<+>-layer on a p-type substrate and also providing three electrically separated electrodes adjacent to one another on an insulating film. CONSTITUTION:In the picture element of row i and column j, when electrode SE= 10V, RE=5V, electrode 21=0V, and n<+>-layer=10V, for example, electrode 4 is accumulated immediately below SE by photoelectric conversion. When only SE is set at zero, well 41 becomes shallow, charges flow to well 42, and the potential of RE changes and it can be read out by bus Xi. Next, when electrode 21 is set at 7V, well 43 becomes shallower than well 42, and charges flow to well 31 of n<+>-layer 22, which is impressed with 10V; and the potential change on RE is canceled out. Further, when n<+>-layer is set at zero and electrode 21 is set at 2V, charges flow from well 31 to 42, and writing is operated regardless of the incident light; and the potential of RE changes and it can be read out by bus Xi. By using bus IGi, the potential of gate 21 is controlled, and by sythesizing picture element group A below one drawn line and picture element group B not lying below the line, or erasing a part of picture element group A, it is possible to correct picture images.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device constituted so that a different voltage is prevented from being charged and an accident such as firing is prevented from occurring by simple constitution when a fixing unit whose input power source specification is different is erroneously loaded. SOLUTION: Connectors 3 electrically connecting an image forming device main body 1 and the fixing unit 2 are formed so that the positions of terminals for transmitting a heater control (turn-on) signal between the main body 1 and the unit 2 are made different according to the type of a supplied commercial power source and the assignment of pins is made different according to the difference of the positions of the terminals. Thus, since the terminal for transmitting the heater control (turn-on) signal between the main body 1 side and the unit 2 side is not connected when the unit 2 being different from the voltage specification of the main body 1 is erroneously installed, the heater control (turn-on) signal is not supplied to the main body 1 side through the unit 1.
