摘要:
An image display apparatus includes an image display element configured to modulate incident light from a light source, a polarization splitting element that has characteristics of transmitting first polarized light and reflecting second polarized light different from the first polarized light and that is configured to synthesize image light from the image display element to be introduced into a projection optical system, and a phase difference plate that is disposed at a side of the projection optical system relative to the polarization splitting element. The phase difference plate has an optic axis in a direction different from a surface normal direction and an in-plane direction of the phase difference plate.
摘要:
The present invention provides an adhesive wheel balance weight capable of drastically reducing costs from those of conventional ones, and a process for producing the same. In an adhesive wheel balance weight (W) comprising a weight body (P) and an adhesive tape (T) for attaching the weight body (P) to a vehicle wheel, the weight body (P) comprises a folded weight comprising a folded metal plate piece. The folded weight of the present invention can be formed from a relatively inexpensive raw material sheet at a high yield rate. It is preferable that the raw material sheet is a zinc-coated steel sheet, because no rust-proofing aftertreatment is necessary and therefore further cost reduction is achieved, and its environmental burden is small.
