Title: Internal-combustion engine and method for its operation
Inventor: ANSONII KUROODO UEEKUMAN
IPC: F02D13/02
Filed: 1991-07-29
Abstract: PURPOSE: To provide an effective intake air supply method mainly in a four-cycle internal combustion engine. CONSTITUTION: In a four-cycle internal combustion engine comprising at least two inlet valves, and means for controlling the timing of the opening and closing of each of the two inlet valves independently, in the case of a light load, the opening of one of the independently controlled inlet valves occurs at A during the exhaust stroke of the engine and the closing thereof occurs at B during the intake stroke. The other inlet valve is opened at C immediately after the start of the compression stroke, and the intake air enters the combustion chamber which generates turbulence, and then it is closed at D. At least some of this turbulent flow is present when combustion occurs. As the load increases, the opening timings of the two inlet valves approach, and at the time of full load, both of them are superimposed during the compression stroke.

IPC: G03G15/14
Filed: 1985-08-28
Abstract: PURPOSE:To easily separate a transfer material from a photosensitive body by irradiating the surface of the photosensitive body through the transfer material from the back of the transfer material superposed to the surface of the photosensitive body and photo-destaticizing the residual electric charge on the surface of the photosensitive body. CONSTITUTION:A light source 8 irradiates light to the surface 1a of the photosensitive body through the transfer material 5. Although negative charge is applied to the transfer material 5 by a transfer device 6, the charge can not be removed by said light irradiation. Therefore, the negative charge of the transfer material 5 is neutralized with the positive charge of the photosensitive body by a corona discharger 11. The charge left on the photosensitive body without being removed by the corona discharger 11 is completely removed by the light source 8. Consequently, the transfer material can be easily separated from the photosensitive body.

Abstract: PURPOSE:To recognize see-through deterioration in a designing process of a glass form by producing a three-dimensional model of the glass form, tracking an angle error caused by the refraction of the parallel incident beams in terms of a virtual curved surface to simulate the see-through distortion and displaying the distribution state of distortion degrees against the glass surface. CONSTITUTION:A geometric three-dimensional model 2 of a glass surface is prepared from the design drawing or the design data of a window glass 1 by a form modeling method using a computer. Then a see-through distortion simulator 4 estimates the parallel beams R1 and R2 which are sent to a virtual screen SC set at the back of the glass from a virtual light source L set outside a car. The optical path formed by a refraction rule is tracked and finally an angle error between two refracted beams R3 and R4 that causes the see-through distortion is calculated. When a visual angle error is produced between both beams R3 and R4, an object seen through seems distorted by the lens effect. The see-through distortions corresponding to the parallax angles calculated at many point on the glass 1 are visually displayed on a see-through distortion degree display device 5 like a display, a printer, etc., in the form of a distortion degree distribution diagram formed along the glass surface.
