Abstract
Abstract A precision positioning system wherein a curable, non-fluid, plastic bonding agent is applied between the object to be positioned and the object on which it is to be positioned and the object is positioned before the bonding agent hardens, whereafter it is fixed in position by the hardening of the bonding agent.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A precision positioning method comprising applying a curable, non-fluid, plastically deformable bonding agent in the form of a non-film adhesive between the mutually contacting portions of a component and the object on which the component is to be positioned, said bonding agent having a viscosity between 10 6 and 10 11 poise and having as its main components a fine powder filler and a curable bonding component, positioning the component to deform the bonding agent before the bonding agent hardens, and releasing the positioned component to be fixed in the positioned orientation by the hardening of the bonding agent.
Claim 2
Dependent Claim
99 words
A precision positioning method comprising applying a curable, non-fluid, plastically deformable bonding agent in the form of a non-film adhesive between the mutually contacting portions of a component and the object on which the component is to be positioned, said bonding agent having a viscosity between 10 6 and 10 11 poise and having as its main components a fine powder filler and a curable bonding component, positioning the component to deform the bonding agent before the bonding agent hardens, and releasing the positioned component to be fixed in the positioned orientation by the hardening of the bonding agent.
Claim 3
Dependent Claim
27 words
A precision positioning method as defined in claim 1 wherein the bonding agent has a yield strength of between 70 g/cm 2 and 20 kg/cm 2 .
Claim 4
Dependent Claim
22 words
A precision positioning method as defined in claim 1 or 2 wherein the curable bonding component is a non-solvent type bonding component.
Claim 5
Dependent Claim
21 words
A precision positioning method as defined in claim 1 wherein the bonding agent undergoes substantially no change in volume during hardening.
Claim 6
Dependent Claim
17 words
A precision positioning method as defined in claim 1 wherein the fine powder filler is a clay.
Claim 7
Dependent Claim
19 words
A precision positioning method as in claim 1 where said viscosity is between 10 7 and 10 10 poise.
Claim 8
Dependent Claim
16 words
A precision positioning method as in claim 1 carried out at a temperature of 10°-40° C.
Claim 9
Dependent Claim
23 words
A precision positioning method as defined in claim 1 wherein the bonding agent includes CaCO 3 and kaoline as the fine powder filler.
Claim 10
Dependent Claim
50 words
A precision positioning method as in claim 1 including the step of determining the amount of settlement in using the bonding agent for the component to be positioned and where said positioning step is such that the component is positioned so as to compensate for the determined amount of settlement.
