What is claimed is:
1. A manufacturing method for an oriented film comprising the steps of;
stretching in two to six times a non-stretched film with moisture percentage adjusted to no more than 10% comprising polyvinyl alcohols or derivatives by heating at no less than 70 C.; and
subsequently annealing by heating again at no less than 70 C. after once cooling at no more than 40 C.
2. The manufacturing method for an oriented film according to claim 1, wherein a rate of strain is set to no less than 1.4 (1s) in said stretching process.
3. The manufacturing method for an oriented film according to claim 1, wherein a non-stretched film is dyed beforehand with iodine or a dichroism dyestuff.
4. The manufacturing method for an oriented film according to claim 1, wherein a stretched film is dyed with iodine or a dichroism dyestuff after the annealing process.
5. A polarizing film comprising an oriented film obtainable by the manufacturing method for an oriented film according to claim 3 or 4.
6. A polarizing plate with an optical transparent protective layer on at least one side of the polarizing film according to claim 5.
7. A visual display using the polarizing plate according to claim 6.
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 computer readable medium storing computer executable instructions that when executed implement a method to control a first feature, the method comprising:
validating an apparatus that removably connects to a first printer, the validating including comparing first data stored within the apparatus to second data stored within the first printer;
enabling the first feature within the first printer utilizing third data stored within the apparatus; and
restricting the apparatus such that the apparatus is no longer operable to enable the first feature within a printer other than the first printer.
2. The medium of claim 1, wherein the first and second data identify the apparatus as authorized for use with the first printer.
3. The medium of claim 1, wherein restricting the apparatus comprises storing fourth data within the apparatus, the fourth data identifying the first printer.
4. The medium of claim 1, wherein the third data comprises the first data.
5. The medium of claim 1, wherein the first feature comprises an addition to a second feature, the second feature already enabled within the first printer.
6. The medium of claim 1, wherein the first feature comprises a memory addition.
7. The medium of claim 1, wherein the first feature comprises a page description language addition.
8. The medium of claim 1, wherein the fourth data comprises the first printer’s serial number.
9. The medium of claim 8, wherein the fourth data additionally comprises the first printer’s part number.
10. The medium of claim 3, further comprising:
revalidating the apparatus upon a reconnection of the apparatus with the first printer;
disabling the first feature; and
unrestricting the apparatus such that the apparatus is again operable to enable the first feature within a printer other than the first printer.
11. The medium of claim 10, wherein unrestricting the apparatus comprises removing the fourth data from the apparatus.
12. A first printer, comprising:
a printhead;
a memory;
a connector to removably connect to an apparatus and to facilitate an exchange of data between the memory and the apparatus;
a validation engine, operable to validate an apparatus that removably connects to the connector, the validating including comparing first data stored within the apparatus, to second data stored within the memory;
a permission engine, operable to enable a first feature utilizing third data stored within the apparatus; and
a restriction engine, operable to send fourth data to the apparatus, to restrict the apparatus such that the apparatus is no longer operable to enable the first feature within a printer other than the first printer.
13. The first printer of claim 12, wherein connector comprises a USB port.
14. The first printer of claim 12, wherein the first feature comprises an upgrade to a second feature, the second feature already enabled within the first printer.
15. The first printer of claim 12, wherein the first feature comprises a memory upgrade.
16. The first printer of claim 12, wherein the first feature comprises a page description language upgrade.
17. The first printer of claim 12, wherein the fourth data comprises the first printer’s serial number
18. The first printer of claim 12, wherein:
the validation engine is additionally configured to revalidate the apparatus upon a reconnection of the apparatus with the first printer;
the permission engine is additionally configured to disable the first feature; and
the restriction engine is additionally configured to unrestrict the apparatus.
19. The first printer of claim 18, wherein unrestricting the apparatus comprises removing the fourth data from the apparatus.
20. A method to control a first feature within printers, the method comprising:
validating an apparatus that removably connects to a first printer via a USB connection, the validating including comparing first data stored within the apparatus to second data stored within the first printer;
enabling the first feature within the first printer utilizing third data stored within the apparatus, the first feature comprising an addition or upgrade to a second feature, the second feature already enabled within the first printer the third data;
restricting the apparatus such that the apparatus is no longer operable to enable the first feature within a printer other than the first printer, including storing fourth data that comprises the first printer’s serial number and part number within the apparatus, the fourth data identifying the first printer;
revalidating the apparatus upon a reconnection with the first printer;
disabling the first feature; and
unrestricting the apparatus such that the apparatus is again operable to enable the first feature within a printer other than the first printer, including removing the fourth data from the apparatus.
