Filed: 1992-09-30
Abstract: PURPOSE:To prevent the seizure of a powder clutch by raising an exciting current gradually in the case of the slip condition of the clutch being materialized in the almost stop state of an automobile with an accelerator depressed and with the brake off. CONSTITUTION:In the depressed state of an accelerator in the case of an automobile being close to the stop state with the brake off, a control circuit 4 judges the slip of a powder clutch 3 from the engine speed which is the input rotating speed to the clutch 3 and from the clutch output rotating speed of a clutch output side rotation sensor 11, and the control circuit 4 outputs a signal to an exciting current driving circuit 10 so as to gradually raise an exciting current to the clutch 3. The locking force of the clutch 3 is thereby strengthened gradually, and load to the engine side is increased to stop the engine. Accordingly, in the case of a wheel getting into a ditch or the like and locked therein, the clutch can be prevented from seizure due to continuous slipping by the depression of the accelerator.

IPC: A61B3/10
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To enable simulation of visibility associated with oscillation, distortion, blurring or the like when a lens system such as progressive power lens is worn. SOLUTION: Eyeballs are turned toward every object point within a visual field, images are caught at a central cavity and put together to form an image, which is defined as turning retinal image and the image thus defined is generated using an image at a specified angle of visual field coming into eyes having a specified center point of turning as original image. A distortion original image associated with a distortion as obtained when the original image is seen through a lens system is generated using a light beam tracing method. PSF on a retina is determined as to an eyeball model by light from an object point of the original image in an optical system comprising the lens system and a spectacles model and the PSF undergoes a convulsion computation with pixels of the distortion original image obtained and the original image. The result is the turning retinal image.  The turning retinal image obtained is edited to obtain an animation image of the turning retinal image. The PSF is determined by setting a sample point at the object point and the PSF other than that using the sample point is determined by a method using an approximation method containing a spline interpolation method.
