Title: High-pressure air hose connecting tool
Inventor: HASEGAWA TAKEO
IPC: F16L37/46
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To safety improve and the workability of attaching and detaching work of a connecting tool by providing a valve mechanism composed of a fixed valve and a turning valve, and an exhaust mechanism for discharging remaining high-pressure air in a tool side hose outward from a connecting tool main body when high-pressure air is shut off from a compressor by the valve mechanism. SOLUTION: When a valve mechanism 4 of a hose connecting tool 1 is made into a closed state, respective valve hoses 46, 46 of a turning valve 44, shut off high-pressure air by a fixed valve 41. An oval elastic material 45 of the turning valve 44 half opens respective valve holes 43, 43 of the fixed valve 41, the valve holes 43, 43 form an exhaust passage by being communicated with a cutout part 51 of the turning valve 44, a recessed groove 48 and a guide hole, and high-pressure air remaining in the tool side hose is discharged outward from the connecting tool 1. If an operating valve of the air tool is accidentally touched when work of the air tool is stopped by the exhaust mechanism, the tool is not operated and is safe, and safety in disconnecting of the connecting tool 1 is improved.

Title: Method for determining pressure distribution in fluid
Inventor: KAWAMOTO SHINJI
IPC: G01L7/00
Filed: 1993-12-17
Abstract: PURPOSE:To improve the predicted accuracy of a pressure distribution without increasing a computation time, by using a spatial slope of time average of flow velocity component in orthogonal direction to a part against which a fluid collides and by reducing the turbulence energy in a fixed part. CONSTITUTION:A correction term P'K is added to a production term PK in the case where an airflow having a velocity distribution 5 around a building 6 is analyzed by using a K-epsilon model. The correction term P'K is displayed by using a slope in the direction X1 normal to a wall and a slope in the direction X3 parallel to the wall, of a time average flow velocity component Un in the direction normal to the wall, and always becomes negative. Therefore, by adding this to the production term PK, the productivity of turbulence energy is controlled in a part 6f against which the flow collides, and a region where the turbulence energy becomes large is placed in the region 4 normally produced. Consequently, a break away phenomenon can be reproduced on the top of the building 6, the excessive estimation of the turbulence energy in the part 6f can be prevented, and the predicted accuracy of a pressure distribution is improved.
