  • Patent number: 5863659
    Abstract: A silicon wafer has a polycrystalline silicon film formed on one main surface. The polycrystalline silicon film has a multilayer structure composed of X layers (X is an integer equal to or greater than two) containing <220> oriented components in different proportions. The proportion of the <220> oriented component in the first polycrystalline silicon layer in contact with the silicon wafer is larger than the respective proportions of the <220> oriented components in the second to X-th polycrystalline silicon layers superposed on the first polycrystalline silicon layer. It becomes possible to provide a silicon wafer whose polycrystalline silicon film possesses high gettering capability and in which stress acting on the silicon wafer is decreased.

  • Patent number: 5853902
    Abstract: A metal support for exhaust gas cleaning has a metal honeycomb core body fabricated by laying a planar sheet on a corrugated sheet and rolling the laminated sheets into a cylindrical configuration. The corrugated sheet has sinusoidal shaped portions having a wave height which is sufficient to contact the adjacent planar sheet and square wave portions which have a wave height which is insufficient to enable contact with the adjacent sheets. The square wave portions have corners which project out beyond the sinusoidal shaped portions and produce agitation and disturb the flow of gas and to induce an increase in the contact efficiency between the gas and surfaces carrying catalytic material. The planar sheet is not limited to continuously flat sheets and can include flat surfaces formed by zigzag or square wave shaped members. These members can be perforate and or made of a mesh material.

  • Patent number: 5851631
    Abstract: Low-cost composite infrared windows that are transparent to long wave infrared radiation (8-12 microns) that provide sufficient strength and impact resistance for automotive-type environments, and the like. The windows may be used with night vision systems for automobiles, surveillance imaging systems, and other applications requiring low cost, long wave infrared windows. In one embodiment, the composite infrared window is a sandwich comprised of a polyethylene plastic film bonded with an acrylic adhesive to a relatively thin (0.015-0.040 inch) silicon substrate. The thin silicon substrate is mechanically stiff and low cost, and transmits in the 8-12 micron bandpass. The thin (0.001-0.007 inch) plastic film provides an exterior particle impact absorbing layer sufficient to enable the use of the window in automotive applications.
