Title: Vessel for contact lens and contact lens taking-out method using the same
Inventor: NAKAGAWA MAKOTO
IPC: A61F9/00
Filed: 2002-09-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a vessel having a mechanism for easily taking out a contact lens without flawing the lens when taking out the contact lens, and a lens taking-out method using this vessel.  <P>SOLUTION: This vessel contains the contact lens, and is composed of a housing part for particularly housing the contact lens, a resin cover for covering the housing part and a sealing sheet for sealing the housing part from above the cover. The vessel can form through-holes at two places or more in a lens housing space when taking out the contact lens. The lens taking-out method uses the vessel. Thus, since a preserving liquid can be discharged by using the through-holes at two places or more when taking out the lens, the preserving liquid is easily thrown away while preventing washing-away of the lens so that the lens can be taken out due to sticking of a lens to the housing part cover without wetting other places with the preserving liquid.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-09-25
Abstract: <P>PROBLEM TO BE SOLVED: To virtually increase the number of output levels of a quantizer for a multi-bit ▵Σ modulator with respect to the hardware that is actually configured.  <P>SOLUTION: An adder 11 receives an input signal and adds a dither to the input signal.

Then c0 to c4 are respectively multiplied by outputs of the integrators 1 to 5, an adder 15 summates the products, a quantizer Q quantizes an output of the adder 15 and feeds back the quantized signal to the subtractor 12. Thus, a quantized multi-bit output is obtained from the quantizer Q. Selecting a value greater than the unity for the coefficients c0 to c4 being multipliers can decrease quantized noise without changing the number of output levels (the number of bits).  <P>COPYRIGHT: (C)2004,JPO
