Title: Multicolor image forming device
Inventor: KIMURA KIYOSHI
IPC: G03G15/01
Filed: 1986-08-27
Abstract: PURPOSE:To obtain a multicolor image which is free of color bleeding and character bleeding by making the base body of a photosensitive body transparent and conductive and providing a transfer assisting device which irradiates the photosensitive body with light from its reverse surface before or during transfer operation. CONSTITUTION:The photosensitive body 40 is constituted by coating a transparent and conductive film with a photosensitive layer. Development on a drum 40 is performed by developing devices 43-45 where toner particles of black, red, and blue are charged and toner images of black, red, and blue are formed one over another. Then, the composite toner image of the toner images of black, red, and blue is irradiated with light by a before-transfer exposure lamp L1 from the reverse surface of the photosensitive body and then transferred onto recording paper 61. Consequently, the potential of the photosensitive body is decreased uniformly in spite of the sticking and nonsticking part of toner and the generation of lines of electric force for scattering the toner is precluded to obtain a multicolor image which is free of bleeding. The transfer paper 61 to which the toner image is transferred is separated from the drum 40 by a separation electrode 51 through AC corona discharging.

Abstract: PURPOSE:To enable continuous operation always without obstruction by changing over and fixing the operating characteristics of another without valve capable of being changed over even though part of a valve with possibility of changing over its operating characteristics is fixed to the operation in the applicable operating characteristics due to malfunction of a valve operating characteristics changeover mechanism. CONSTITUTION:Assuming that a coupling changeover means 21a makes malfunc tion, other normally operating coupling changeover means 21b, 21c, 21d are put in coupling disengaged condition and fixed if the first named means is fixed to the low speed valve operation characteristics LVT. Thus, all valves can be operated in the low speed valve operating characteristics. This is trans ferred to the high torque side valve operating characteristics when the number of revolutions Ne<N1, where N1 is specified number of engine revolutions, and turned into the low torque side valve operating characteristics when Ne>Nl. Thus the transmission concerned is controlled with a control map selected, which corresponds to the engine output in the condition that the high torque side valve operating characteristics are used while Ne<N1.

Filed: 1990-07-31
Abstract: PURPOSE:To make it possible to automatically and accurately regulate mold clamping force without interrupting molding cycle with the regulation of the mold clamping force by a method wherein mold clamping is performed by judging whether the mold clamping force, which is measured at mold clamping, lies within the allowable error range of the set mold clamping force or not. CONSTITUTION:When mold clamping action is started by driving a servo motor 10, a central controller 14 controls the speed of a crosshead 6 by detecting the position of the crosshead 6 at all times on the basis of the signal sent from a sensor 13, which is provided on the servo motor 10, so as to perform mold clamping, when the crosshead 6 is held at the pre-set mold clamping position. At said mold clamping, the clamping force is measured with a mold clamping force measuring device 20 so as to judge whether the measured value lies within the allowable error range of the set mold clamping force or not. When the measured value lies within the allowable range, the mold clamping regulating process is brought to an end at the time of judgement. When the measured value does not lie within the allowable range, the mold clamping force regulation value as the position regulation value of the crosshead 6 at the mold clamping is calculated from the difference between the measured value and the set mold clamping force so as to bring the regulation of the mold clamping force to an end by setting the mold clamping position of the crosshead for the future.

CONSTITUTION:A section for change of machining conditions of a corner part and a standard of decision for change of the machining conditions are set previously at a memory area 103d of a RAM 103. Then a graphic defining sentence and a motion defining sentence are produced and supplied with no consideration of the machining condition changing section and the machining conditions. Thus, a processor 102 is defined as '1-i'. The end point of the i-th block is calculated from both graphic and motion defining sentences and it is checked whether or not said end point is equal to the end point of the path of a laser beam. If not, it is checked whether the outside of the corner is equal to a parts or not. If so, the machining conditions set previously based on the standard of decision are applied. Then an NC part programming is executed so that an original state is recovered at a point separated from the corner by a fixed distance. Thus, it is possible to keep the machining accuracy at the corner part in a simple method.

CONSTITUTION:A microprocessor 8 changes over a switch 13 with application of a power supply and subtraction 11 is performed between the speed reference value and the frequency/voltage conversion value of the output of an optical sensor 2. Then the error voltage is applied to an actuator motor 6 and the track pulses are counted to shift a magnetic head 3 into a target reference servo track. Then the witch 13 is hanged over to produce the position reference value and one of 4-phase output signals of the sensor 2 is selected (7) and undergoes subtraction9. Thus a motor 6 is revolved and halted at error voltage O (designated track). Then the servo signal of a magnetic disk 1 is detected by the head 3 and processed (15) and an actual difference is calculated between a reference servo track and a center. The off-track value stored previously is corrected for fine adjustement of the head 3. As a result, the shift time of the head 3 is shortened.
