  • Patent number: 9899112
    Abstract: A structure configuring a ridge filter has line symmetry about a line vertical to a depth direction passing the center of the structure. A small structure obtained in such a way that the structure is divided by this line has a bilaterally asymmetric shape about a center line in an iterative direction, and has a point symmetric shape about an intersection between the center line in the iterative direction and the center line in the depth direction. Thicknesses in the iterative direction of an uppermost stream surface and a lowermost stream surface in the depth direction are equal to each other. The structure is configured so that a thick portion in the iterative direction of the uppermost stream surface and the lowermost stream surface is not present in the depth direction.

  • Publication number: 20170175216
    Abstract: A method of producing a spring which reduces time required for a heat treatment step of eliminating a machining strain generated by a forming step is provided. This production method is provided with a forming step (S10) of forming a spring steel material into a spring shape and a heat treatment step (S12) of eliminating a machining strain generated in the spring steel material by the forming step. The heat treatment step is executed by electrically heating the spring steel material by applying a current thereto. The heat treatment step has a first step of heating the spring steel material to a predetermined set temperature and a second step of keeping the spring steel material at the set temperature for a predetermined set time period subsequent to the first step. The set temperature is set to be higher than 430° C. but not higher than 500° C.
