Title: Steering rod for vehicle and its manufacture
Inventor: ISOGAWA YUKIHIRO
IPC: B62D3/12
Filed: 1982-06-11
Abstract: PURPOSE:To manufacture a light weight steering rod at high working accuracy and material yield in manufacturing a steering rod for a vehicle by plastic working such as casting using upper and lower dies by using a hollow pipe for material of the rod. CONSTITUTION:Lower half in the section of a hollow pipe 38 of a blank material is set to a caliber 32 provided in a lower die 30 and pressed by impact using an upper punch 40 having a caliber 46 consisting of combination of a dividing face 42, a rack tooth form 44 and a cylindrical face of the same diameter with the caliber 32 to form a steering rod 16 in which a partial cylindrical part 48 and desired rack tooth form shaped part 49 (14) are formed.

Title: Flowing-down regulating sheet
Inventor: TAKAHASHI TAKASHI
IPC: F24S10/60
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To control the behavior of a fluid in response to the number of holes, disposition configuration, and density by providing relatively small through-holes arranged densely along the flowing-down direction of the fluid and forming portions to which the fluid is more likely to adhere in a region where the through-holes are disposed and disposing portions to which the fluid is unlikely to adhere thereamong. SOLUTION: One regulation line 2b is disposed at an interval from a correcting regulation line 2a located at the most left side of each regulation line bundle 2, and three regulation lines 2c to 2e are disposed in a position relation in close vicinity to and adjoining to the regulation line 2b, and further two regulation lines 2f, 2g are disposed at an interval from the regulation lines 2c. With use of these plurality of the regulation lines a flowing-down guide passage is constructed which takes the three regulation lines 2c to 2e substantially at the halfway as a main flowing-down passage. Flowing-down fluid is restricted and flows down by permitting adhesion force of the fluid to act on this region because a contact area of the region where through-holes are formed is larger than the other part.
