An IR-cut filter comprises a crystal plate and a multilayer film formed on one side of the crystal plate. The multilayer film is composed of first thin films made of a high refractive index material and second thin films made of a low refractive index material, which are alternately layered. The multilayer film is composed of a first layer, a second layer and a third layer sequentially from one side of the crystal plate. Film thicknesses of the layered first and second thin films differ from layer to layer so that the layers have different thicknesses. The layers have thicknesses which are sequentially increased. The multilayer film is provided with a sharpness prevention means for preventing a sharp change in transmittance within a visible region. The sharpness prevention means provides an inflection point at a wavelength band in which transmittance changes sharply.

A temperature control unit of hot rolling machine that avoids any sharp temperature change of rolling material at a place near the outlet of the rolling machine to thereby realize a high-precision control of sheet thickness. Accordingly, in a hot rolling machine equipped with multiple rolling stands continually disposed and further with multiple cooling units for cooling of rolling material, first, the cooling water pressure of each of the cooling units is computed using up to the upper limit pressure preferentially from one of the multiple cooling units disposed on the inlet side of the rolling machine on the basis of the target temperature and inlet actual temperature of the rolling material. Subsequently, on the basis of the target temperature and outlet actual temperature of the rolling material, so as to reduce any deviation between the target temperature and the outlet actual temperature, there is computed the cooling water pressure of one of the cooling units in operation disposed nearest the outlet of the rolling machine. At that stage, when the cooling water pressure of the cooling unit under control reaches the upper limit pressure, the control object is changed to the cooling unit disposed adjacent to the outlet of the rolling machine. On the other hand, when the cooling water pressure reaches the lower limit pressure, the control object is changed to the cooling unit disposed adjacent to the inlet of the rolling machine.

The invention relates to an energy-saving control method and system for revolving speed of an engine. The method comprises the following steps: acquiring required running speed and load required power; and setting a revolving speed value of the engine to be minimum revolving speed on the premise of meeting the required running speed and the load required power. By the energy-saving control method and system for the revolving speed of the engine, the engine runs at economical revolving speed as much as possible on the promise of meeting a vehicle speed requirement and a power requirement, so that the purpose of saving fuel is achieved. Meanwhile, when the revolving speed set value of the engine is changed, a hydraulic system is adjusted in real time so as to guarantee stable running speed and link before and after change of the revolving speed, and stability and driving comfort are good. A power requirement serves as a first priority, and the revolving speed of the engine can be relatively high when high speed or large torque is required. Therefore, a vehicle can meet optional speed requirements. But the required speed of the vehicle is not maximum in most cases, and the advantage of fuel saving can also be played fully.

To provide a coil spring with a load axis offset from a geometric axis, and to provide a vehicular suspension system using the same. The coil spring 1 is wound with its winding diameter larger at an intermediate in the axial direction than at the end.
