Title: Vertical shaft pelton water turbine
Inventor: NIIKURA YOSHIYUKI
IPC: F03B1/00
Filed: 1986-11-10
Abstract: PURPOSE:To eliminate a water feed pump and to reduce an equipment cost, by a method wherein, through utilization of energy of water injected from a bucket during running of a water turbine, water is taken in through an intake hole, and is guided to the water passage pipe of an oil cooler. CONSTITUTION:Water is injected through a nozzle, not shown, to the bucket 10 of a water turbine runner during running of a Pelton water turbine, and through reaction of the water, the water turbine runner is rotated. In this case, water injected from the bucket 10 and collided with a housing 7 is collected by a bow shaped collector 8 situated at the upper part of a housing 7, and the water is guided through an intake hole 9 to a water feed pipe 4 to introduce it to a passage pipe 5. During the passage of the water through the water passage pipe the lubricating oil is cooled, and thereafter, the water is discharged to a water passage in the housing 7 after passing an exhaust pipe 6 from the outlet side of the water passage pipe 5. This constitution eliminates a water feed pump for cooling and a strainer, and reduces a cost.

Filed: 1994-11-01
Abstract: PURPOSE: To reduce the dynamic cage stress by setting the ratio of the diameter of a cylindrical roller to the diameter of the bearing pitch circle of a cylindrical roller bearing to be a specific small value. CONSTITUTION: An inner ring 11 of a cylindrical roller bearing 10 is coupled with a turbocharger shaft 15 through an inner bearing bush 13.

Title: Formation of metallic film on surface of resin substrate
Inventor: YAMADA SHUGO
IPC: C23C14/20
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To enhance the adhesion of a metallic film on the smooth surface of a resin substrate by subjecting the surface of the resin substrate to OH or COOH group imparting treatment, further subjecting it to porphyrin fixation treatment and forming the metallic film on the surface of the substrate by wet plating or a vapor growth method. SOLUTION: The porphyrin fixation treatment is preferably carried out by applying a solution containing a porphyrin having COOH groups in a side chain. Since dehydration condensation is caused between OH or COOH groups imparted to the resin substrate and the COOH groups in the side chain of the porphyrin, the porphyrin is tightly fixed on the surface of the substrate and the metallic film adheres tightly. After the porphyrin-containing solution is applied, heat treatment is preferably carried out at 50-100 deg.C for about 0.5-2 hr.
