Title: Liquid-cooled rotor
Inventor: MURATA KOUICHI
IPC: H02K9/19
Filed: 1978-05-25
Abstract: PURPOSE: To reduce the thermal bending vibration of the windings of a liquid- cooled rotor, by providing a throttle unit between the coupled part of a feed or discharge header fot the rotor windings for one magnetic pole and a main water feed or discharge pipe to regulate the quantity of fed or discharged water.  
     CONSTITUTION: The conical throttle unit 11, by which the cross-sectional area of the opening of a water feed riser 9 on the side of the outer diameter of the rotor can be adjusted at the rotor side of the feed water header 8, is located outside an end ring support 13 shrinkage-fitted on the peripheral part of an end ring 3 so that the throttle unit can be removed. The quantity of cooling water introduced to the windings 2 can thus be regulated in a water feed and discharge circuit comprising an inside discharge pipe 8a, the feed water riser 9, the feed water header 7 for the N-pole and S-sole, a water branch pipe 5, the rotor windings 2, a water branch pipe 5 of the water discharge header 12, a discharge riser 10 and a discharge pipe 8b. Because the throttle unit 11 can be finely adjusted by the end ring support 13, the unbalanced cooling of the windings can be prevented to minimize their vibration due to the thermal deformation of the windings.

Title: Cylinder and cylinder liner
Inventor: URANO SHIGERU
IPC: C21D9/14
Filed: 1979-05-22
Abstract: PURPOSE:To reduce blow-bye in a Diesel engine or the like by providing annular hardened layers near the piston top-dead point on the inner surface of the cylinder liner. CONSTITUTION:A plurality of annular layers 3 hardened by the laser beam irradiation are provided in the region 2 near the piston top-dead point on the inner surface of a liner 1. Due to the elasticity of the base metal of the liner 1, the torsion of a piston ring 5, or the like, the difference in abrasion arises between the hardened layers 3 having an excellent durability and the gap 4 between the layers 3 and 3. Due to the abrasion difference, the gap 4 is formed into a cavity, which can hold lubricating oil, therefore, the durability can be greatly improved. Moreover, since the hardened layers and the contacting surface of the piston ring are contacted with each other by annular line contacts, the sealing efficiency can be improved, so that blow-bye can be largely reduced.
