摘要： A low-cost contact detection sensor and contact detection method for easily detecting a contact by a third party is provided. A contact detection sensor comprises an antireflection structure including structure elements having a predetermined shape which are put in an array periodically at a pitch smaller than a wavelength of visible spectrum; and a substrate including the antireflection structure in at least a part of a surface portion thereof. The antireflection structure distinguishes whether the detection target is contacted by a human body or not based on a change in reflectance which occurs to an area of the detection target contacted by the human body when the detection target is contacted by the human body.

摘要： A premixing section for supplying a fuel-air mixture to a homogeneous combustion chamber includes a first fuel nozzle disposed along an axis, a second fuel nozzle disposed to surround the outer periphery of the first fuel nozzle, and a premixing/pre-evaporating chamber. The first fuel nozzle is a diffusion combustion type nozzle and supplies the fuel-air mixture from an air blast-type nozzle tip directly to the homogeneous combustion chamber. The second fuel nozzle is a premixing/pre-evaporating type nozzle and supplies the fuel-air mixture from an air blast-type nozzle tip to the premixing/pre-evaporating chamber, so that the fuel-air mixture promoted in mixing and evaporation in the premixing/pre-evaporating chamber, is supplied via a swirler to the homogeneous combustion chamber. With the above arrangement, the atomization of the fuel enhances the emission characteristics.

摘要： A selective shading device has a number of shading plates or planar members and a supporting body that holds the plates or planar members in such a manner that they are arrranged radially with respect to an optical axis. The device blocks sagittal bundles of rays. A preferred example of the supporting body is a cylindrical frame that holds the shading plates perpendicularly to the inner surface thereof. Alternatively, the shading planar members are formed within a lens element along the edge thereof.

摘要： A projection lens having a large aperture ratio has 3 units for projecting an enlargemen of an image appearing on a CRT onto a screen. The first unit from the screen has a negative power so that the entrance pupil is moved toward the screen to thereby improve off-axis vignetting factor. The second unit consists of two positive power lens elements so that the positive power of the entire system is shared by the second unit and the temperature characteristic is improved by using a positive power glass lens element as one of the two positive power lens elements. The third unit has a negative power to correct curvature of field.
