Title: Canister deterioration detector
Inventor: FUJIMOTO TAKESHI
IPC: F02D45/00
Filed: 2001-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a canister deterioration detector capable of detecting deterioration of a canister precisely with a simple structure. SOLUTION: When the execution condition for detecting deterioration of the canister is satisfied as indicated in the figure 9 (a), the internal pressures in the tank (A and B Fig.) corresponding to a small purge flow rate and to a large purge flow rate within a prescribed range of the purge flow rate as indicated in (b) are detected. If the air-permeability of the canister is secured, a large negative pressure will not be drawn into an evaporation purge system because an atmospheric air releasing valve is usually closed. However, if the air-permeability of the canister is lowered, the canister is in the same condition as when the atmospheric air releasing valve is closed, and therefore, the internal pressure in the tank varies according to the purge flow rate. In the detector, deterioration of the canister is detected based on the variation of the internal pressure in the tank.

Title: Manufacturing method for gas discharge panel
Inventor: MURAI RYUICHI
IPC: H01J11/46
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a gas discharge panel effective in improving the productivity of panel manufacturing by increasing the number of arranged panels like a vertical arrangement even if the heights of the manufacturing devices such as a heating furnace are set equal to conventional ones by considering the advantages of a horizontal arrangement that a ventilation pipe is hard to fall and liquid drop never occurs and by using them as premises.
