Abstract: A method of forming an electrostatic latent image includes printing operation and toner recovering operation. The printing operation includes charging, forming an electrostatic latent image, developing, and transferring operations. The toner recovering operation includes the step of charging the photosensitive drum in timed relation to the rotation of the photosensitive drum after printing operation so that reversely charged toner deposited on the charging roller migrates from the charging roller to the photosensitive drum. The toner migrated from the charging roller to the photosensitive drum is recovered into a developer. An apparatus for forming an image includes a charging roller, photosensitive drum, developing roller, and transfer roller.

The apparatus includes a carrier belt; a transfer roller for carrying the toner adhering to the surface of the photosensitive body toward the carrier belt; a transfer power supply for applying to the transfer roller a first voltage that causes the normal-charged toner adhering to the surface of the photosensitive body to be transferred to the recording medium on the carrier belt, and a second voltage, of opposite polarity to the first voltage, that causes the reverse-charged toner adhering to the surface of the photosensitive body to be transferred to the carrier belt; and a carrier belt cleaning blade.

Abstract: Disclosed herein is a plasma processing apparatus having a dielectric member through which electromagnetic-waves are introduced into the reaction vessel to excite a plasma therein. A metallic resistor plate 3 is buried in the dielectric member to reduce capacitive coupling components in the plasma and to function as the electromagnetic-wave transmitting and heating member. The metallic resistor plate 3 is provided with a DC power supply 5 and a current controller 7 for feeding a controlled direct current to the metallic ressitor plate so as to elevate and control the temperature of the dielectric member 2. Sputtering of the dielectric member is prevented by the reduction of the capacitive coupling component, while deposition of etching products on the dielectric is suppressed by the controlled heating of the dielectric, thereby alleviating the problem of contaminating particle generation and increasing etching condition stability.

Abstract: A color printer has multiple printing heads that print dots in different colors, one dot line at a time. Each line is divided into at least two parts. For each printing head, the printer has an image data memory that stores data for at least two dot lines. When a printing head prints one dot line, data for each part of the dot line are taken from an independently-selected line in the image data memory. The image lines are selected so as to correct positional skew between different printing heads.

Abstract: A plasma processing apparatus comprises a reaction chamber to hold a high-density plasma and having a dielectric plate window, a spiral coil placed outside the reaction chamber and close to the dielectric window, and a lower electrode which holds a wafer to be processed in place and installed in the reaction chamber facing the dielectric plate. A first radio frequency current supply to the coil, a mechanism for varying the distance between the coil and the dielectric plate window, and a second radio frequency voltage supply to the lower electrode is provided. Excellent uniformity of the ion current density of the plasma and hence etching rate is achieved by making the thickness of a central part of the dielectric plate window thicker than its peripheral parts. Also, the uniformity of the plasma and the etching rate is achieved by making the induction field produced by the coil axially symmetrical about the axial center of the reaction chamber.

Abstract: Proposed is a novel heat-sealable connector sheet, by which very reliable electric connection can be obtained with electrode terminals on an electronic device or a circuit board, consisting of a flexible insulating plastic substrate sheet and a patterned electroconductive layer formed thereon from an electroconductive paste with an overcoating layer of an insulating melt-flowable adhesive. Different from the electroconductive pastes used in conventional connector sheets, the electroconductive paste used here is compounded with an appropriate amount of relatively coarse particles of an insulating material having elasticity, e.g., plastic resins. The patterned electroconductive layer is formed from such a composite conductive paste in such a fashion that the insulating particles are fully embedded in the conductive paste but forming protrusions on the surface of the patterned electroconductive layer which accordingly exhibits a rugged appearance.

Abstract: A data storing device has at least first to third registers. When the first register is accessed, the second register is set into an accessible state in a preset cycle succeeding to a cycle in which the first register is accessed. The same address as that of the second register is assigned to the third register and access to the third register is inhibited in a preset cycle in which the second register is accessed. An access control circuit controls permission/inhibition of access to the second and third registers.

Abstract: In a transformer protection system, data of voltages and currents detected at individual terminals of a transformer connected to an electric power system are supplied to a computer. The computer computes driving point admittances or shunt admittances of the transformer on the basis of the voltage and current data and predetermined transfer admittances of the transformer and decides that an internal fault has occurred in the transformer when the values of the driving point admittances or shunt admittances deviate from pre-set reference values, thereby disconnecting the transformer from the electric power system.
