摘要： A thermal-type flow sensor capable of generating a monotonously increasing output over a time period of transition from a reverse flow to a forward flow with a simplified structure while exhibiting high sensitivity in the measurement of flow rate in the forward direction. The flow sensor includes a plurality of heat generating portions implemented by upstream heat-sensitive resistor (4) and downstream heat-sensitive resistor (5) within a passage (19) as viewed in a direction in which fluid flows through the passage (19), for thereby measuring a flow rate or a flowing speed of the fluid on the basis of heat transfer phenomenon taking place between the heat generating portions and the fluid. The flow sensor includes a heating current control means (30, 31, 32) for controlling heating currents flowing through the heat-sensitive resistors (4, 5) so that temperatures of the plurality of heat generating portions increase by predetermined values relative to the temperature of the fluid, a means (34) for determining difference between heating currents flowing through the upstream heat generating portion and the downstream heat generating portion, and means (35 to 37) for detecting the flowing speed or the flow rate of the fluid on the basis of the difference between the heating currents.

摘要： A metallized film capacitor formed from a pair of metallized films. Each of the metallized films includes a dielectric film with a metal evaporated electrode formed thereon. One electrode has longitudinal electrode partitioning lines and a plurality of small blocks separated by fuse areas, while the other electrode does not. Each metallized film is formed by moving the film over a screen cylinder having a side wall with openings formed therein. A nozzle is disposed inside the screen cylinder, adjacent to the side wall. Oil is ejected from the nozzle, while the screen cylinder is rotated. The oil passes through the side wall and is deposited on the film to form a pattern thereon. Subsequently, evaporated metal is deposited on the film.
