Title: Oil-pressure circuit for construction working vehicle
Inventor: KUBOMOTO WATARU
IPC: E02F9/22
Filed: 1983-06-30
Abstract: PURPOSE:To avoid the zig-zag going of a construction working vehicle by operating other actuators during the running operation by a method in which a switch valve for operatig a running motor is connected in tandem to a switch valve for operating other actuators, and a throttle valve is provided to a convergent oil path. CONSTITUTION:A switch valve 4 for operating a running motor 3 is connected in tandem to other switch valves 6, 8 and 10, and a switch valve 17 for operating a running motor 16 is also connected in tandem to other switch valves 19, 20 and 21. During the simple period, the valve 27 is closed, the oil path 26 is interrupted and when the switch valves 4 and 17 are operated only the running motors 3 and 16 are operated due to no flow of oil to the other switch valves. On the sloping road or during the turning operation, the valve 27 is set to the open side, the oil path 26 is opened, and when the switch valves 4 and 17 are operated, the running motors 3 and 16 are operated. When the switch valve 6 is operated, the turning motor 5 is operated and the operation of the running motors 3 and 16 is delayed. When flow dividers 36 and 37 are added to before and behind the valve 27, the straightforwardness of running and concurrent operabilities of each actuator are raised. The zig-zag going of a construction working vehicle during the operation period can be avoided by operation of other actuators.

Title: Adjusting system for evaporation amount of carbon dioxide
Inventor: SANO SADAJIRO
IPC: F01K25/08
Filed: 1995-04-03
Abstract: PURPOSE: To adjust the amount of carbon dioxide used for a power generation system in response to the usage thereof by providing many evaporation kettles for heating and evaporating carbon dioxide and adjusting the number of the kettles. CONSTITUTION: Critical temperature of carbon dioxide is high as being 31 deg.C, and it can be easily evaporated with ground heat and the like, and further it has critical pressure of 85 atmosphere to cause carbon dioxide to become considerably high pressure. However, it is relatively difficult to adjust the amount of evaporation thereof when much carbon oxide is heated with one heating tank so that a method is adopted wherein many evaporation kettles 1 are used and the number of the evapoation kettles 1 is adjusted by adjusting the amount of individual heating. Further, a pressure valve 2 is provided on the evaporation kettle 1 to prevent vapor from reversely flowing, and vapor is sent out upon heating.  Hereby, there can be dealt with variations of the amount of evaporation required upon power generation, etc., where liquefied carbon dioxide is heated above critical temperature for evaporation into high pressure vapor.
