摘要： An intake VVT mechanism includes: link mechanisms and connected to an intake camshaft and operated to change a phase of an intake valve; and a control pin sliding on a guide plate along a guide groove to allow the link mechanism to operate; a control pin sliding on the guide plate along a guide groove to allow the link mechanism to operate. The control pin is detached from an end of the guide groove when the control pins and are moved in a direction allowing the phase to be retarded until the control pin abuts against an end of the guide groove.

摘要： A method of grinding the outer circumferential surface of a workpiece 5 formed of a hard and brittle material into a predetermined shape using a grinding wheel while rotating the workpiece 5 is disclosed. The method includes plunge grinding the workpiece 5 at an arbitrary portion (plunge ground portion 21) in the longitudinal direction of the workpiece 5 by causing the grinding wheel to come in contact with the workpiece 5 in a direction which intersects a rotational axis 8 of the workpiece 5, and traverse grinding the workpiece 5 toward the plunge ground portion 21 by moving the grinding wheel relative to the workpiece 5 in a direction parallel to the rotational axis 8 of the workpiece 5. This allows the outer circumferential surface of the workpiece made of a hard and brittle material, such as a honeycomb structure used for a DPF, to be ground into a predetermined shape in a short time, and prevents occurrence of chipping during grinding.

摘要： The present invention relates to a method for cleaning heavy hydrocarbon scale from a shell and tube heat exchanger or other such equipment incorporated in a device in a petroleum refining plant or the like that processes petroleum hydrocarbons as a raw material. A mixture of petroleum-derived hydrocarbon A which can dissolve the oil component of the heavy hydrocarbon scale and an oxygen-containing polar organic compound B that promotes dissolution and dispersion is employed as the organic cleaning solvent. As a result, the heavy hydrocarbon scale can be removed with surety within a short period of time at low cost.

摘要： A device and method for filtering out the noise generated due to coding of image data signals. The device has a threshold determining unit, a binary index unit, a filter selecting unit, and an adaptive filtering unit. The threshold determining unit 4 divides each pixel of the input image data into two gray levels. The binary indexes defined by the gray level are checked by a window with a prescribed size. If the region in the window is determined to be a homogeneous region, a heterogeneous region, or an impulse noise region (block 5), the filter selecting unit selects a filter corresponding to the determined region, and the image data is processed by the selected filter.

摘要： In a device for controlling the flow rate of a hydraulic operating fluid from a pump to a hydraulic motor for driving an engine cooling fan in a vehicle by modifying either the cross sectional opening area of a variable flow constriction means in the fluid conducting passage while maintaining a constant pressure difference across the flow constriction means by a pressure control valve responsive to the pressure difference across the flow constriction means or the pressure difference by selectively partly leaking the pressure transmitted from the downstream side of the flow constriction means to a rear side of the pressure control valve, a cold state relief means is provided to temporarily relieve the rear side of the pressure control valve at cold start of the engine to avoid abnormally high fluid pressure being supplied to the motor due to delayed response of the pressure control valve under high viscosity of the operating fluid at low temperature.
