Title: Method of brazing to copper member
Inventor: KAJITA SUSUMU
IPC: B23K1/20
Filed: 1988-07-23
Abstract: PURPOSE:To prevent the erosion of a brazing filler metal and to improve joint strength by forming an Ni layer via a Cr layer to a Cu member, then executing a brazing treatment on the Ni layer. CONSTITUTION:The Cr layer 5 is formed by a wet plating method, etc., on the Cu member 1 and the Ni layer 3 is formed by plating, etc., on the Cr layer 5. Further, the Ni layer 3 is subjected to the brazing treatment thereupon by using the brazing filler metal 2 having good wettability with the Ni layer 3. The brazing filler metal 2 melts at about 800 deg.C to wet the Ni layer 3. The secure brazing is thus effected. The diffusion of the Ni layer 3 and the Ag, etc., in the brazing filler metal 2 does not take place at the brazing temp. The leaching of the metal in the brazing filler metal into the Cu member at the time of brazing is prevented by the intervention of the Cr layer 5 and the Ni layer 3 in this way. The erosion of the brazing filler metal 2 is, therefore, prevented and since the wettability of the Ni layer 3 and the brazing filler metal 2 is good, the joint strength is improved.

Title: Dry-type transformer device for generator excitation
Inventor: UEHARA TATSUMI
IPC: H01F27/08
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To ensure cooling air at all times, even while a generator is off by providing a power supply device which supplies power to a cooling fan from a dry-type excitation transformer wherein an air duct is installed. SOLUTION: When a generator 9 is off, a disconnecting switch 10 is open. However, since there is no breaker such as the disconnecting switch 10 between a dry-type transformer 1 and an IPB 12 of a main circuit, the dry-type transformer 1 is excited at all times. Since a cooling fan power supply transformer 16 of the dry-type transformer 1 is connected to a secondary side of the dry-type transformer 1, it is possible to receive power supply of a cooling fan 5 from the cooling fan power supply transformer 16. In this way, it is possible at all times to ensure power supply of the cooling fan 5 for cooling heat generated by no-load such as core loss which is generated by excitation of a primary side of the dry-type transformer 1 for excitation, while a power plant is off.  Furthermore, even when a station system is blacked out, it is not necessary to supply power from a distribution panel switchgear, and cooling air of a dry-type transformer can be ensued by always ensuring power supply of a cooling fan.

Title: Toothed belt
Inventor: TSUCHIYA YOSHIFUMI
IPC: F16G1/28
Filed: 1989-07-18
Abstract: PURPOSE:To suppress the metallic sound generated in the high speed revolution and prevent the vibration of a belt by drilling a through hole at the width center part of the tooth bottom part of the tooth in the pulley shaft direction meshed with the teeth of a pulley which are formed on the underside of the belt. CONSTITUTION:A through hole 6 is drilled at the width center part of the tooth bottom part 5 of a tooth formed on the underside of a belt 3 meshed with the teeth of a pulley 1. Therefore, the air nipped between the tooth top part and the tooth bottom part 5 is discharged in the radial direction of the pulley 1 through the through hole 6. In order to secure the discharge, a plurality of through holes 6 may be drilled when the width of the belt 3 increases more, or the discharge range may be increased as elliptics in the width direction. Since the discharge passage is formed in the direction free from the interference with the advance path of the succeeding belt teeth 4, the trouble for the discharge to be cut off in the insufficient stage is prevented.
