CONSTITUTION:An interlayer insulating film 3 made of silicon oxide is formed on first aluminum wirings 2 of lower wirings of predetermined pattern formed on a substrate 1, and a negative type photoresist film 4 is formed on the entire surface. Then, a photomask formed with the pattern of the interconnections 2 is reused to expose and develop to open a window 4a, with it as a mask it is etched to reduce the film 3 exposed in the window 4a substantially equal to the thickness of the wirings 2 and the film 4 is removed. Then, the surface of the film 3 is substantially flattened. After a photoresist film 5 is again formed on the entire surface, a window 5a is opened with the photomask, with it as a mask the film 3 is etched to open a through-hole 6 on the wirings 2. When the film 5 is removed and second aluminum interconnections 7 are formed as upper interconnections in a desired pattern, they are connected via the hole with the interconnections 2 to form a 2-layer interconnection structure.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress power consumption not more than a prescribed value by exactly knowing the power consumption of an automatic vending machine without requiring much cost, and switching the machine to power saving operation based on the power consumption. SOLUTION: The input current of an automatic vending machine is detected by a current sensor 11.

When the power consumption reaches a set value, the turning-on limitation of an illuminator and the power saving operation of a cooler/heater 7 are performed. Further, the power consumption for a fixed period such as monthly power consumption, for example, is set and while managing the daily power consumption not more than that set value, the turning-on of the illuminator 9 and the operation of the cooler/heater 7 are controlled.

Title: Driving method for plasma display
Inventor: TANAKA AKIO
IPC: G09G3/294
Filed: 1991-04-18
Abstract: PURPOSE:To lessen the erroneous lighting which arises by diffusion of stimulated ions in the longitudinal direction of a plasma display panel by selecting adjacent scanning side electrodes apart in time. CONSTITUTION:The selection of the adjacent lines is executed apart by 4 Hsync periods. The gases stimulated by an electric discharge diffuse successively to m+1 lines when the (m) line is assumed to be selected and is subjected to the electric discharge. The stimulated gases return to the base level as time passes by. The density of the stimulated gases decreases and the number thereof is few upon lapse of the 4 Hsync. Consequently, the erroneous lighting does not arise any more when the m+1 lines are selected after the 4 Hsyn periods.
