Filed: 1993-11-26
Abstract: PURPOSE:To automatically predict a danger from collected management information without depending on the skill of an observer and to previously prevent the operation deterioration of a plant. CONSTITUTION:Management information from the plant is slectively collected in a data collection part 1. A time-sequential pattern recognition part 2 time- sequentially monitors management information collected by the data collection part 1 and the change is compared with a comparison pattern (time-sequential pattern assuming abnormal time) which is previously registered in accordance with collected management information.

Abstract: PURPOSE:To properly carry out extraction from drink extraction materials by providing both a water sprinkling plate having a large number of small holes arranged on the upper position of a filter body and a piston body by which the water supplied in the inside of a cylinder is forcibly fed toward a filter body through the water sprinkling plate. CONSTITUTION:When a coffee cartridge 3 is placed on a bottom cover body 22, a flange part 2B is placed on a ringlike placing part 33, and a filter part 2A is positioned in the inside of a recessed part 31. Between the filter part 4 and the recessed part 31, a space is formed. This space becomes a temporary reserving space of the water passed through the coffee cartridge 3. When a cup of hot water is supplied to the inside of a cylinder part 23 from a water- boiling/hot-water supply part 10 through a hot-water feed pipe 16, the hot water passes through a large number of small holes 5 of a water sprinkling plate 4, and then is slowly and evenly sprinkled all over the entire region of the upper surface of the filter part 2A. Thus, since the hot water slowly permeates into drink extraction materials, contact time of the hot water and the drink extraction materials is prolonged, and also the inside of the cartridge 3 turns into a steaming condition, and coffee essencecan sufficiently be extracted.

Title: Manufacture of semiconductor device
Inventor: SAITO TADASHI
IPC: H01L21/28
Filed: 1992-11-06
Abstract: PURPOSE:To improve the productivity of a semiconductor element having a T-shaped gate electrode. CONSTITUTION:A gate electrode formation window 48a is formed on a lower layer mask 48 by etching the lower layer mask 48 through a resist 52. Another resist 54 is formed on the lower layer mask 48 to expose the resist 54 by use of an exposure mask. Then, the resist 54 is developed to form another gate electrode formation window in the resist 54. By arranging the exposure amount of the resist 54 to be smaller than that of the resist 52 even when a common exposure mask is used, it is possible to form another gate electrode formation window wider than the window 48a. Therefore, by the reduced projection exposure method, the exposure amount can be controlled without using the EB direct writing method, thus making it possible to form the narrower window 48a for the formation of a gate electrode and another window having a wider width.
