Title: Disc brake device for rolling stock
Inventor: YAMADA HIROYUKI
IPC: B61H5/00
Filed: 1990-11-30
Abstract: PURPOSE:To enable a disc brake device to have a compact design and light weight by applying a lever type construction between a power generation section and a brake operation section via a pin or the like, and enabling a joint section for supporting a brake body on a mating member to be capable of oscillation in a horizontal direction for support on a guide pin. CONSTITUTION:When a hydraulic cylinder 3 expands, a brake lever 10' turns about a lever pin 5 as a fulcrum and moves only in right and left directions, guided by a guide pin 6. A lining 8 fitted to a brake lever 10 pushes a disc 4 at right angles, thereby actuating a brake. On the other hand, the brake lever 10' turns about the lever pin 5 as a fulcrum and, therefore, a lining 8' does not act on the disc 5 at right angles, thereby forming one of causes for the partial abrasion of the lining 8'. In order to prevent the occurrence of the aforesaid partial abrasion, a lining support pin 15 is provided between the brake lever 10' and the lining 8'. According to the aforesaid construction, a brake force can be applied to the plane of brake action at right angles, when the lining and disc are in slidable contact with each other, thereby keeping the guide pin 6 free from a pinching effect.

Filed: 1993-12-24
Abstract: PURPOSE:To obtain output from solar cells to the maximum extent by always maintaining the inlet voltage from the solar cells at around the voltage at the point of highest efficiency. CONSTITUTION:A controller 9 of a converter 8 detects inlet voltage Di and inlet current of the converter 8 and calculates the output of the solar cells 7 (the product of inlet voltage Di and inlet current).
