1. An image sensor comprising:
(a) an array of pixels arranged into two or more subarrays and each subarray captures charge;
(b) an output charge-coupled device that receives charge from the array of pixels; wherein the output charge-coupled device is divided into substantially two equal first and second portions in which only one portion receives charge from a subarray, and the first portion of the charge-coupled device operates as a charge-multiplying charge-coupled device in which charge is amplified, and the second portion of the charge-coupled device does not amplify charge; and
(c) two or more fast dumps positioned between the array of pixels and the output charge-coupled device so that the dumps control which portion of the output charge-coupled device receive charge from the respective subarray.
2. The image sensor as in claim 1 further comprising a plurality of gates for the output charge-coupled device that is arranged as a pseudo-two phase charge-coupled device.
3. The image sensor as in claim 1 further comprising a plurality of gates for the output charge-coupled device that is arranged as a four phase charge-coupled device.
4. A camera comprising:
an image sensor comprising:
(a) an array of pixels arranged into two or more subarrays and each subarray captures charge;
(b) an output charge-coupled device that receives charge from the array of pixels; wherein the output charge-coupled device is divided into substantially two equal first and second portions in which only one portion receives charge from a subarray, and the first portion of the charge-coupled device operates as a charge-multiplying charge-coupled device in which charge is amplified, and the second portion of the charge-coupled device does not amplify charge
(c) two or more fast dumps positioned between the array of pixels and the output charge-coupled device so that the dumps control which portion of the output charge-coupled device receive charge from the respective subarray.
5. The camera as in claim 4 further comprising a plurality of gates for the output charge-coupled device that is arranged as a pseudo-two phase charge-coupled device.
6. The camera as in claim 4 further comprising a plurality of gates for the output charge-coupled device that is arranged as a four phase charge-coupled device.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A guide wire comprising:
a wire member including a welded portion formed by welding a first wire disposed on the distal side of said wire member to a second wire disposed on the proximal side from said first wire and made from a material having an elastic modulus larger than that of said first wire, said welded portion being made substantially smooth; and
a cover layer provided on the outer periphery of said wire member covering at least said welded portion between said first wire and said second wire.
2. A guide wire comprising:
a wire member including a welded portion formed by welding a first wire disposed on the distal side of said wire member to a second wire disposed on the proximal side from said first wire and made from a material having an elastic modulus larger than that of said first wire; and
a cover layer provided on the outer periphery of said wire member covering at least said welded portion between said first wire and said second wire;
wherein said welded portion has a projection projecting in the outer peripheral direction.
3. A guide wire comprising:
a wire member including a welded portion formed by welding a first wire disposed on the distal side of said wire member to a second wire disposed on the proximal side from said first wire and made from a material having an elastic modulus larger than that of said first wire; and
a cover layer provided on the outer periphery of said wire member covering at least said welded portion between said first wire and said second wire; and
a distal-side cover layer disposed on the distal side from said cover layer, said distal-side cover layer being made from a material different from that of said cover layer.
4. A guide wire according to claim 3, wherein said cover layer is formed in such a manner that said wire member is substantially not heated at the time of covering said wire member with said cover layer, and said distal-side cover layer is formed in such a manner that said wire member is heated at the time of covering said wire member with said distal-side cover layer.
5. A guide wire comprising:
a wire member including a welded portion formed by welding a first wire disposed on the distal side of said wire member to a second wire disposed on the proximal side from said first wire and made from a material having an elastic modulus larger than that of said first wire; and
a cover layer provided on the outer periphery of said wire member covering at least said welded portion between said first wire and said second wire; and
a proximal-side cover layer disposed on the proximal side from said cover layer, said proximal-side cover layer being made from a material different from that of said cover layer.
6. A guide wire according to claim 5, wherein said cover layer is formed in such a manner that said wire member is substantially not heated at the time of covering said wire member with said cover layer, and said proximal-side cover layer is formed in such a manner that said wire member is heated at the time of covering said wire member with said proximal-side cover layer.
