Abstract:
The object of the present invention is to form a chromium-oxide film, excellent in corrosion resistance, without containing an oxide film of other metal onto the metallic material. The chromium-oxide passivation film, excellent in corrosion resistance, without containing the oxide film of other metal can be formed inexpensively and in a short time, and a fluid supplying system for safely supplying fluid with hard corrosivity is able to be provided. One step of forming the passivation film consisting of a chromium oxide layer by giving heat treatment, in an oxidizing atmosphere, after coating chromium on the metallic material having a surface roughness (Ra) not more than 1.5 μm.
Abstract:
A dielectric resonator antenna which emits an electric wave by having a dielectric body resonate is disclosed. A magnetic material is contained in the electric body, thereby increasing the relative permeability to more than 1 and lowering the relative permittivity. Consequently, the Q-value of the resonance can be lowered while maintaining the rate of wavelength shortening. With this technique, a broadband dielectric resonator antenna can be realized.

Abstract:
In a bonding apparatus for bonding under pressure a pressure-bonding portion, the concentration of water in a pressure-bonding portion atmosphere inside the apparatus is set smaller than that in an atmosphere outside the apparatus, thereby enabling pressure bonding under low-temperature and low-pressure conditions. In this case, the amount of adsorbed water on each surface of a bonding metal terminal and a to-be-bonded metal terminal forming the pressure-bonding portion is set to 1×1016 molecules/cm2 or less.

Abstract:
An image display device capable of reducing the burden on a passenger and reducing the occurrence of motion sickness, by giving the passenger, through a visual sense, perception (visually induced self-motion perception) of his/her own body moving while viewing an image of a TV and the like in a vehicle, and thus by matching visual information to vestibular information obtained from the motion of the vehicle, particularly to a sense of rotation and somatosensory information which are detected by his/her semicircular canals, is provided. The image display device includes: a behavior detection section (101) for detecting a behavior of a vehicle; a background image generation section (102) for generating a background image based on the behavior detected by the behavior detection section (101); an image generation section (103) for generating an image; an image transformation section (104) for, based on the behavior detected by the behavior detection section (101), transforming the image generated by the image generation section (103); a composition section (105) for making a composite image of the background image generated by the background image generation section (102) and the image transformed by the image transformation section (104); and a display section (106) for displaying the composite image made by the composition section (105).
