Title: Brake device
Inventor: HARORUDO AARU SHIBII
IPC: F16D65/18
Filed: 1981-05-07
Abstract: A brake system for an off-highway vehicle which includes a fluid pressure actuated multi-disc brake and a fluid pressure control system. Engagement of the multi-disc brake is effected by a fluid operated piston having multiple effective pressure areas. Fluid pressure applied to a certain of the effective pressure areas urges the piston in a brake applying direction; fluid pressure applied to the other of the pressure areas urges the piston in a brake releasing direction. The fluid pressure control system controls the communication of pressurized fluid to the effective pressure areas to provide both the brake applying and brake releasing functions. Redundant fluid pressure circuits supply pressurized fluid to the brake applying effective pressure areas. In the event of failure, the control system is operative to interrupt fluid flow to the failed circuit.

Title: Paper money treating device and method for smoothing crease
Inventor: MOCHIZUKI AKIRA
IPC: G07D9/00
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a fault such as a carrying jam and the stacked amount of paper money from being reduced even in the case paper money is forming creases on it by providing the paper money treating device with a 2nd smoothing part for heating and pressing a sheet of paper money treated by a 1st smoothing part by a heat roller and an elastic roller. SOLUTION: A sheet of creased paper money carried into a smoothing mechanism is bent within a prescribed curvature by a bending roller 16 and a gate 11 on the basis of the operation of the gate 11. The creased paper money is restricted by an elastic roller 19 and a carrying roller 18 so that creases on the bent creased paper money are not restored. The deformed and restricted paper money is carried to the 2nd smoothing part. That is, the deformed and restricted paper money passes through a carrier path formed by a guide 5 and comes into contact with a heat-resistant elastic roller 14. The roller 14 is heated by being rotated by coming into contact with a heat roller 15 driven by a driving source. Thus the creased paper money is carried and heated along the roller 14.
