Abstract:
The thin film AMA has a substrate, an actuator, a common line, and a reflecting member (180). The substrate has an electrical wiring and a connecting terminal and the actuator has a supporting layer (130), a bottom electrode (135), a top electrode (145), and an active layer (140). The common line (150) is formed on a portion of actuator and is connected to top electrode (145). The electrical wiring and connecting terminal may not be damaged because the actuator is formed on a portion of substrate adjacent to the portion where electrical wiring and connecting terminal are formed. The voltage drop of a second signal can be minimized because common line (150) is formed thickly on a portion of the actuator, so a sufficient second signal is applied to the top electrode (145). The flatness of the reflecting member (180) may be enhanced because the reflecting member (180) is formed on a second sacrificial layer.
Abstract:
Thin film AMA in an optical projection system and a method for manufacturing the same are disclosed. The thin film AMA has a substrate having electrical wiring and a connecting terminal, an actuator, and a reflecting member (160). The actuator has a supporting layer (120), a bottom electrode (125), an active layer (130), and a top electrode (140). The supporting layer (120) has a first portion attached beneath the bottom electrode and a second portion exposed out of the bottom electrode. The reflecting member (160) is formed on the second portion of supporting layer (120). The supporting layer (120) tilts with the actuator. Hence, the thin film AMA has much enhanced light efficiency of the light reflected by the reflecting member (160) by minimizing the area of the actuator and maximizing the area of the reflecting member (160), so the quality of a picture projected onto a screen is greatly increased.
Abstract:
A system for processing both a composite video television (TV) signal and a video cassette recorder (VCR) playback signal containing a combined noise canceller and comb filter (108) sharing a single delay line (1H DL) and a 3.58 MHz oscillator (424) that drives a quadrature demodulator (424, 454, 456, 458, 460, 462 and 464) for demodulating both playback chrominance signals extracted from the playback signal and TV chrominance signals extracted from the TV signal. The system also provides automatic gain control to both the composite video TV signal and the VCR playback signal.
Abstract:
Disclosed is an indicator device for visually denoting the amount of filled dust in a dust container of a vacuum cleaner. The indicator device operates based on a vacuum pressure difference created between an air suction port and an outlet of the vacuum cleaner. When a vacuum pressure difference is created between the air suction port and the outlet of the vacuum cleaner, a disc-shaped colored film and a circular rotating member positioned in an upper cap of the indicator device receive an atmosphere air from the exterior of the indicator device and denote the amount of dust filled in the dust container. For this purpose, a colored film is separated by 3 x N (N is an integer) times and colored in three primary colors of light of red, green and blue or in three primary colors of red, yellow and blue. The user of the vacuum cleaner can notice the operating state of the vacuum cleaner or the replacement time of the dust container by observing the color change of the colored film through the transparent upper surface of the upper cap installed at a through groove formed at the hood of the vacuum cleaner and exposed to the outside of the vacuum cleaner.
Abstract:
Disclosed is a method for uniformly cooking rice of an electric rice cooking kettle capable of cooking uniform rice regardless of a change of months. The method can cook uniform rice without adjusting a water amount during cooking of the rice, by controlling heat preserving times thereof according to a change of months. The method has an advantage in that it can uniformly cook rice, when cooking a rice with standard water amount, by automatically performing a rice cooking process according to differences in the rice's composition corresponding to a difference in the month of the year.

A 2-position 3-way solenoid valve (100) is disclosed having a hinged structure. The solenoid valve includes a hollow cylindrical housing (20) and first and second covers (21 and 22) hermetically coupled to both ends of the housing (20). The first cover has first and third ports (30, 34), and the housing has a second port (32). A diaphragm divides an inner chamber within the housing into first (24) and second chambers (26), and the first to third ports are communicated with the first chamber (24). The second chamber (26) contains an armature (60), a solenoid assembly (68) and a core (58), and the armature is fixed to a push rod (56) which extends to the first chamber through a diaphragm hole. A first spool for opening/closing the first port (30) is provided to an end of the push rod (56) within the first chamber (24). A step is provided to coupling portion of the first spool and the push rod (56) by the difference of their diameters, and a valve lever (546) extends perpendicularly to the push rod (56) to engage with the step (43). A second spool for opening/closing the third port is fixed to an end of the valve lever (546) in a perpendicular relationship. The valve lever (546) is connected to, by a pin (52), a supporting rod having one end thereof fixed to the first cover (21) to rock both ends of the valve lever (546). A spring (44) is disposed, between the valve lever (546) and the first cover (21) to surround the first spool.
Abstract:
A 2-position 3-way solenoid valve having first, second and third ports and first and second chambers. The first chamber is communicated with the first port and the second chamber is communicated with the second and third ports. The chambers are partitioned by a barrier wall and are communicated with each other by an opening formed to the barrier wall. In response to a valve-actuated signal, a spool is moved in lengthwise direction, so that the opening and the third port are opened alternatively. When the third port is closed, the hydraulic pressure generated from a hydraulic pump is supplied to a brake wheel cylinder through the first and second ports to increase braking pressure. When the opening is closed, the hydraulic pressure within the brake wheel cylinder is decreased through the second and third ports to decrease braking pressure.
