Abstract
Abstract A method of manufacturing a honeycomb rotor-sealing device, which is to be applied to a space between a rotor means and a stationary casing means surrounding said rotor means and open cells of which are adapted to face on the periphery of said rotor means for preventing fluid from passing therethrough, including steps of forming a thin sheet of metal or the like into an embossed sheet as to provide a plurality of cells adjacently arranged and open at each side thereof, fixing said embossed sheet on to a supporting plate at one side thereof and cutting a surface portion thereof away from said embossed sheet for providing an increased number of open cells over at the side opposite to that at which said embossed sheet is fixed on to said supporting plate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A method of manufacturing a honeycomb rotor-sealing device, which is to be applied to a space between a rotor means and a stationary casing means surrounding said rotor means and open cells of which are adapted to face on the periphery of said rotor means for preventing fluid from passing therethrough, including steps of forming a thin sheet of metal or the like into an embossed sheet as to provide a plurality of cells adjacently arranged and open at each side thereof, fixing said embossed sheet on to a supporting plate at one side thereof and cutting a surface portion thereof away from said embossed sheet for providing an increased number of open cells over at the side opposite to that at which said embossed sheet is fixed on to said supporting plate.
Claim 2
Independent Claim
133 words
A method of manufacturing a honeycomb rotor-sealing device, which is to be applied to a space between a rotor means and a stationary casing means surrounding said rotor means and open cells of which are adapted to face on the periphery of said rotor means for preventing fluid from passing therethrough, including steps of forming a thin sheet of metal or the like into an embossed sheet as to provide a plurality of cells adjacently arranged and open at each side thereof, fixing said embossed sheet on to a supporting plate at one side thereof and cutting a surface portion thereof away from said embossed sheet for providing an increased number of open cells over at the side opposite to that at which said embossed sheet is fixed on to said supporting plate.
Claim 3
Dependent Claim
130 words
A honeycomb rotor-sealing device, which is to be applied to a space between a rotor means and a stationary casing means surrounding said rotor means and open cells of which are adapted to face on the periphery of said rotor means for preventing fluid from passing therethrough, manufactured by steps of forming a thin sheet of metal or the like into an embossed sheet as to provide a plurality of cells adjacently arranged and open at each side thereof, fixing said embossed sheet on to a supporting plate at one side thereof and cutting a surface portion thereof away from said embossed sheet for providing an increased number of open cells over at the side opposite to that at which said embossed sheet is fixed on to said supporting plate.
Claim 4
Dependent Claim
130 words
A honeycomb rotor-sealing device, which is to be applied to a space between a rotor means and a stationary casing means surrounding said rotor means and open cells of which are adapted to face on the periphery of said rotor means for preventing fluid from passing therethrough, manufactured by steps of forming a thin sheet of metal or the like into an embossed sheet as to provide a plurality of cells adjacently arranged and open at each side thereof, fixing said embossed sheet on to a supporting plate at one side thereof and cutting a surface portion thereof away from said embossed sheet for providing an increased number of open cells over at the side opposite to that at which said embossed sheet is fixed on to said supporting plate.
Claim 5
Dependent Claim
24 words
A honeycomb rotor-sealing device as defined in claim 2 wherein said plurality of cells provided on said embossed sheet are shaped into circular cylinder.
Claim 6
Dependent Claim
23 words
A honeycomb rotor-sealing device as defined in claim 2 wherein said plurality of cells provided on said embossed sheet are shaped into hexagonal.
Claim 7
Dependent Claim
24 words
A honeycomb rotor-sealting device as defined in claim 2 wherein said embossed sheet is fixed on to said supporting plate by means of brazing.
Claim 8
Dependent Claim
24 words
A honeycomb rotor-sealing device as defined in claim 2 wherein said embossed sheet is fixed on to said supporting plate by means of soldering.
Claim 9
Dependent Claim
26 words
A honeycomb rotor-sealing device as defined in claim 2 wherein said embossed sheet is fixed on to said supporting plate by means of a binding agent.
