摘要： PROBLEM TO BE SOLVED: To provide a head-up display which is small in surface reflection noise and chromatic aberration. SOLUTION: This head-up display device 1 is so constituted that a signal light 31 emitted by a display unit 5 is projected on a hologram combiner 10 and its diffracted light 32 is viewed. The signal light 31 is P-polarized light and diffraction characteristics of a hologram are so set that the angle α of incidence of the signal light 31 becomes nearly equal to the angle β of reflection of the diffracted light 32. The surface of the hologram combiner 10 which is irradiated with the signal light 31 is coated not to reflect light.

摘要： PROBLEM TO BE SOLVED: To always achieve stable startability, even while an internal combustion engine is cool. SOLUTION: A lubrication oil heating portion 60 is disposed adjacent to an oil filter 50, a location where lubrication oil is surely stored in a lubrication oil supply passage that supplies the lubrication oil to each of sliding portions, such as a crankshaft and crank pin of an internal combustion engine. with this configuration, lubrication oil is heated directly in a PTC thermistor 70 of the lubrication oil heating portion 60, when the internal combustion engine starts. This raises the temperature of the lubrication oil and decreases viscosity efficiently. Therefore output decreases due to brake horsepower loss in the internal combustion engine can be prevented.
