Abstract: PURPOSE:To raise the charging efficiency of another cylinder of a multicylinder internal combustion engine and increase its total output, by providing a control valve in an intake passage, closing the valve in the deceleration of the engine and compensating the degree of opening of the valve depending on the rotational frequency of the engine. CONSTITUTION:Throttle valves 7, 8 are provided in intake passages 4, 6 for cylinders 1, 2. The control valve 9 is provided in only the intake passage 4 under a communication hole 10 for both the intake passages 4, 6. The valve 9 is connected to a moving diaphragm unit 12 through levers 11, 13. The negative pressure chamber 12d of the diaphragm unit 12 is connected to the negative pressure chamber 16c of a controller 16, to which the intake negative pressure is transmitted through a negative pressure pipe 17. When the engine is decelerated, the control valve 9 is closed by the negative pressure transmitted through the pipe 17 and the negative pressure chambers 16c, 12d. Pressurized air is conducted from an air pump 18 into the negative pressure chamber 16c to change the degree of opening of the valve 9 in the range from a low speed to a high one.

Title: Image overlay method in copying machine
Inventor: OONISHI HAJIME
IPC: G03G13/26
Filed: 1980-06-19
Abstract: PURPOSE:To simplify 2-image-overlay, by selecting relationship between illumination of each original for exposure and sensitivity of a photoreceptor, and the like so as to convert a certain position of the photoreceptor into a black image after development when it is exposed to black at least once in twice exposures, and to convert another certain position into a white image when it is exposed to light both in the 2 exposures. CONSTITUTION:When 2 kinds of originals are overlaid, that is, double exposures are carried out, the first exposure is set to about the half of the total exposure. The surface potential of a photosensitive drum corresponding to the white ground of the first original image becomes a state not sufficiently decayed (Point C1), and if this is developed in such a state, it is converted into a whole black image. Then, in the second exposure, the drum is exposed to the same exposure as the first exposure, i.e. the half of the total exposure, for the second overlaid original. The gamma value of development is raised in the part low in surface potential so as to convert this electrostatic latent image exposed to half the exposure into a black level, thus permitting 2 sheets of originals to be synthesized easily by a positive developing method.
