A reflective plateis arranged so as to reflect infrared rays, radiated from a heating wire, outside of a heaterand may be made of steel. A number of cavitiesare arranged on the surface of the reflective plate. Since the cavitieshave an aspect ratio of 0.17 to 0.7, the infrared reflectance can be increased compared to a reflector with no cavities.

Reflector and apparatus including the reflector

A method of drilling holes in a work piece includes receiving a laser beam directed along an optical path; and directing the laser beam through a beam former, disposed in the optical path, to form an array of sub-beams of a first pitch size. The method demagnifies the array of sub-beams to form a reduced-size pattern of a second pitch size on the work piece. The array of sub-beams is translated, or moved in a perpendicular direction to the optical path. After translating the array of sub-beams, the method forms the reduced-size pattern of the second pitch size on the work piece. The second pitch size may be smaller than the wavelength of the laser beam.

An energy converter according to the present invention includes a heat source (radiator), which receives externally applied energy and raises its temperature, thereby emitting electromagnetic radiations, and a radiation cut portion (mesh) for cutting down infrared radiations, of which the wavelengths are longer than a predetermined wavelength. The meshis a woven or knitted mesh of metal wires. The openings of the woven or knitted mesh have an aperture size that is smaller than the predetermined wavelength.

Energy converter and method of making the same

An energy converter according to the present invention includes a filamentfor converting given energy into electromagnetic waves and radiating the waves, and a radiation suppressing portion for suppressing some of the electromagnetic waves (e.g., infrared rays), which have been radiated from the filamentand of which the wavelengths exceed a predetermined value. The radiation suppressing portion has a bundleof fine wires, of which the axial direction is aligned with a direction in which the electromagnetic waves propagate with their radiations suppressed.

An incandescent bulb filament having a flat Light-emitting surface and high Lamp efficiency and an incandescent bulb using this filament are provided. This incandescent bulb filament is characterized in that it is a filament of ribbon shape placed on one plane, and it includes: spaced portions which are placed side by side with spaces; and connecting portions which connect the spaced portions electrically in series. Each spaced portion has a thickness that is one half the width of the spaced portion or more, and the space between at least one pair of adjacent spaced portions is less than five times the width of the spaced portion.

A microcavity forming device is provided for making microcavities in a tungsten wire. The microcavity forming device includes a source of particles; a housing for receiving a heated tungsten wire; and a plurality of jet nozzles disposed in the housing for spraying the particles toward the heated tungsten wire. The particles are 0.35&#x2013;0.75 micron in diameter. The heated tungsten wire is received in the housing and the jet nozzles spray the particles toward the tungsten wire to form the microcavities in the tungsten wire.

Method and apparatus for forming discrete microcavities in a filament wire using microparticles

A microchannel forming device is provided for making microchannels in a wire. The microchannel forming device includes a plurality of dice for receiving a heated wire spaced along a longitudinal axis. Each die has a circumferential surface forming an opening, and teeth projecting normally from the surface and terminating in the opening. As the heated wire is drawn through the opening of each die, the teeth engage the heated wire to form longitudinal microchannels therein.
