What is claimed is:
1. A lithographic process for producing a microstructure by means of a direct write system in which predetermined areas of a photosensitive layer are exposed by means of a focussed light beam in order to produce structures, wherein the intensity of the beam is modulated as a function of the spatial frequency of the microstructure to be produced, and the structure is produced serially by removing the photosensitive layer in accordance with a scanned grid pattern.
2. A lithographic process according to claim 1, wherein said focussed light beam is a laser beam.
3. A lithographic process according to claim 1, wherein the intensity of the focussed beam is increased as the spatial frequency of the microstructure to be produced increases.
4. A lithographic process according to claim 1, wherein a light-sensitive resist is used which switches at an exposure beam energy level of between 40 to 60%.
5. A lithographic process according to claim 4, wherein said light-sensitive resist switches at an exposure beam energy level of about 50%.
6. A lithographic process according to claim 1, wherein, after a first exposure step and subsequent development and formation of a first set of structures, a second exposure step is carried out in which the exposure is carried out with a predetermined displacement, and a second set of structures is produced having a desired offset relative to the first set.
7. A process according to claim 6, wherein the displacement for the second exposure step is chosen such that after final development, the second set of structures are situated in intermediate spaces formed between adjacent structures of the first set during the first exposure step.
8. A process according to claim 1, wherein, after a first exposure step and subsequent development and formation of a first set of structures, a second exposure step is carried out without an offset, and a second set of structures is produced precisely superimposed on the first set of structures.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A container, tastefully decorated, to temporarily conceal bags of trash in a generally residential setting, comprising:
a front panel generally upright;
a door, detachable from said front panel;
a rear panel mutually parallel and opposite said front generally upright and lower in elevation than said front;
a left side panel upright, spanning between said front panel and said rear panel;
a right side panel upright, mutually parallel and opposite said left side;
a left handle generally centered upon said left side;
a right handle generally centered upon said right side;
a bottom panel generally oriented flat and joining to said front panel, said rear panel, said left side, and said right side upon the perimeter edges of said bottom, said bottom panel having two or more wheels; and,
a lid opposite said bottom panel; connecting to said door by one or more second hinges and connecting to said rear panel by one or more first hinges;
whereby said container is located at a convenient place, said lid and said door are raised, trash bags are placed into said container as filled, and at a regular interval the trash bags are removed from said container for disposal.
2. The container of claim 1 further comprising:
said bottom panel having two spaced apart mutually parallel wheels fixed in direction, two spaced apart movable wheels that turn into the direction of motion, and a loop descending from said bottom generally proximate said front and permitting anchoring of said container.
3. The container of claim 1 further comprising:
said door having a pull extending outwards from said door generally centered and towards said bottom panel, and a width narrower than said front panel but flaring outwards proximate to said lid; and,
said front panel having symmetric shoulders flanking said door, said shoulders rounding and narrowing in width as said door flares outward in width.
4. The container of claim 1 further comprising:
said left handle having a frusto-conical shape joined to said left side panel forming a hollow shape; and,
said right handle having a frusto-conical shape joined to said right side panel forming a hollow shape;
whereby said left handle and said right handle permit insertion of one or more flower pots.
5. The container of claim 4 wherein said door, said front panel, said left side panel, said rear panel, and said right side panel have a decorative band located proximate to said lid and in cooperation with said left handle and said right handle.
6. The container of claim 1 further comprising:
a grid installing within said container upon said bottom panel, having a generally rectangular shape; and,
said bottom panel having a plurality of holes.
7. The container of claim 1 further comprising:
one or more cylinders extending from said lid to said left side and said right side and assisting in raising said lid from said front panel.
8. The container of claim 1 further comprising:
said front panel, said rear panel, said lid, said bottom panel having a rectangular shape;
said door having rounded corners opposite said lid; and,
said left side panel and said right side panel having a trapezoidal shape.
