1. A check processing method comprising:
scanning a back of a check having no authorization data printed thereon;
scanning a front of the check to capture a front image of the check, the front of the check being preprinted with magnetic ink characters;
generating authorization data indicating that processing payment of the check has been completed and that the check is valid based on a reading of the magnetic ink characters and a response from an external analysis source, the authorization data being generated electronically without printing the authorization data;
generating an electronic merged image by electronically combining back image data captured during the scanning of the back of the check with the generated authorization data, the electronic merged image being generated without printing any data; and
storing the electronic merged image with the front image.
2. A medium readable by a machine embodying a program of instructions executable by the machine to perform a check processing method, the program of instructions comprising:
instructions for scanning a back of a check having no authorization data printed thereon;
instructions for scanning a front of the check to capture a front image of the check, the front of the check being preprinted with magnetic ink characters;
instructions for generating authorization data indicating that processing payment of the check has been completed and that the check is valid based on a reading of the magnetic ink characters and a response from an external analysis source, the authorization data being generated electronically without printing the authorization data;
instructions for generating an electronic merged image by electronically combining back image data captured during the scanning of the back of the check with the generated authorization data, the electronic merged image being generated without printing any data; and
instructions for storing the electronic merged image with the front image.
3. A check processing apparatus which is connectable to a host device, the check processing apparatus comprising:
a transportation path for conveying a check from a check insertion opening to an exit opening;
a transportation mechanism that conveys the check through the transportation path;
a scanning component that captures both a back image of the check and a front image of the check conveyed through the transportation path;
an authorization data component that sends a request to the host device for electronic authorization data indicating that the check is valid based on a response from an external analysis source, wherein the authorization data component receives the requested electronic authorization data from the host device if the check is determined to be valid;
a merged image generating component that generates an electronic merged image by combining back image data captured during the capturing of the back image with the received electronic authorization data without printing the authorization data; and
a memory that stores the electronic merged image with the front image.
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 metal-graphite brush comprising a copper-graphite brush body into which a metal sulfide solid lubricant is mixed and a lead embedded in the copper-graphite brush body characterized in that
a concentration of the metal sulfide solid lubricant in the copper-graphite brush body is made different between in a neighborhood of the lead in the copper-graphite brush body and a portion of the copper-graphite brush body with which a commutator of a rotational electric armature is to be in contact and
a concentration of the metal sulfide solid lubricant in the neighborhood of the lead in the copper-graphite brush body is lower than a concentration of the metal sulfide solid lubricant in the portion of the copper-graphite brush body in contact with the commutator,
wherein the concentration of the metal sulfide solid lubricant in the neighborhood of the lead in the copper-graphite brush body is less than 1 wt. %.
2. A metal-graphite brush of claim 1, characterized in that the concentration of the metal sulfide lubricant in the neighborhood of the lead in the copper-graphite brush body is substantially 0%.
3. A metal-graphite brush of claim 1, characterized in that the metal sulfide solid lubricant is at least a member of a group comprising molybdenum disulfide and tungsten disulfide.
4. A metal-graphite brush of claim 1, characterized in that the concentration of the metal sulfide solid lubricant in the portion of the copper-graphite brush body in contact with the commutator is from 1 to 5 wt. %.
5. A metal-graphite brush of claim 1, characterized in that the lead is a nonelectroplated copper lead.
6. A metal-graphite brush comprising a copper-graphite brush body to which a metal sulfide solid lubricant is added and a lead embedded in the copper-graphite brush body characterized in that
a concentration of the metal sulfide solid lubricant in the copper-graphite brush body is made different between in a neighborhood of the lead in the copper-graphite brush body and a portion of the copper-graphite brush body with which a commutator of a rotational electric armature is to be in contact,
a concentration of the metal sulfide solid lubricant in the neighborhood of the lead in the copper-graphite brush body is lower than a concentration of the metal sulfide solid lubricant in the portion of the copper-graphite brush body in contact with the commutator and
the neighborhood of the lead in the copper-graphite brush body and the portion of the copper-graphite brush body in contact with the commutator are made of different powder materials in concentrations of the metal sulfide solid lubricant and shaped in a common mold,
wherein the concentration of the metal sulfide solid lubricant in the neighborhood of the lead in the copper-graphite brush body is less than 1 wt. %.
7. A metal-graphite brush of claim 6, characterized in that said powder materials are further different in copper concentrations
and that the copper concentration of the neighborhood of the lead is higher than the copper concentration of said portion.
