Abstract: PURPOSE: A drain valve of an air tank for a vehicle is provided to regulate pressure automatically and to discharge impurities like water at the same time as operating manually. CONSTITUTION: In a drain valve(2), a space is divided by a diaphragm(10) to retain upper and lower pressure chambers(12,14) in upper and lower cases(4,6). In the middle part of the upper pressure chamber, a hole(16) is determined for combining a connector(18) composed of a hollow bolt and a filter is embedded in the connector by combining an air tank(22). By the drain valve, if the pressure inside the air tank increases, air is introduced into the upper pressure chamber through a filter(20). In the state, when the pressure of the lower pressure chamber is lower than the pressure of the upper pressure chamber, an edge around a main body(24) of the diaphragm is pressed and air flows in the lower pressure chamber. And, when the pressure inside the air tank becomes low, the pressure of the upper pressure chamber is lowered as well. Herein, the main body rises up for opening a drain hole(28).

Abstract: PURPOSE: A method for manufacturing a semiconductor memory device is to minimize the oxidization of a dispersion barrier metallic film and to prevent a dielectric rate from being deteriorated by securing the crystallization of BST((Ba,Sr)TiO3). CONSTITUTION: An interlayer dielectric(11) formed on a substrate(10) is selectively etched to expose the substrate, thereby forming a contact hole. A plug of which a barrier metallic film(14) is formed thereon is formed in the contact hole. The first conductive film(16) for a bottom electrode of a capacitor is formed on the plug. The first conductive film is made of any one of It, Pt, Ru, and superconductive oxide. A dielectric film(17) of (Ba,Sr)TiO3 is deposited on the bottom electrode at a temperature lower than 400 deg.C. The substrate is rapidly annealed to achieve the crystallization of the dielectric. A top electrode of the capacitor is formed on the dielectric film.

Abstract: PURPOSE: A method for managing multicasting channels is provided to transmit added control signals to an F/W(Firm Ware) block of a circuit board for a subscriber interface. CONSTITUTION: A connection which is a data transmission path of multicasting channels is set up(S110). A subscriber F/W(Firm Ware) block decides whether a control signal A is applied from an upper S/W(Software) block(S120). If so, the subscriber F/W block transmits a signal B to the upper S/W block(S130). A subscriber board intercepts a data signal for transmission(S140). If the control signal A is not applied, the subscriber F/W block decides whether an active control signal C is applied(S150). If the active control signal C is applied to the subscriber F/W block, the subscriber F/W block transmits a signal D to the upper S/W block(S160). If the data signal is transmitted from the subscriber, the data signal is copied to be transmitted to corresponding channels(S180).

Abstract: PURPOSE: A memory repair circuit using a MOS structure anti-fuse is provided to repair erroneous cell by manufacturing the anti-fuse with MOS transistors and by programming the anti-fuse adequately. CONSTITUTION: The memory repair circuit includes a plurality of anti-fuse devices(10), a latch and a redundancy block(50). The anti-fuse devices are programmed when a source voltage is applied on the first electrode and a negative voltage is applied on the second electrode. The latch detects the program state of the anti-fuse device and latches the result. The redundancy block replaces the erroneous cell with the redundancy cell according to the output of the latch. The memory repair circuit further includes an address multiplexer as well as a voltage generator. The address multiplexer selects the anti-fuse device. The voltage generator supplies the negative voltage to the second electrode of the anti-fuse device.

Abstract: PURPOSE: To tightly contact the tip end of a lead to a frame placement stage by providing a groove at a part corresponding to the tip end of a pressing part of a frame presser on the upper surface of the frame placement stage. CONSTITUTION: Related to the upper surface of a frame placement stage 3, a groove 8 is formed at a part which receives the tip end of a pressing part 4a of a frame presser 4. When a lead 1b is pressed to a frame placement stage 3 with a rear end of the pressing part 4a of the frame presser 4, the pressing force is released to the groove 8 so that the tip end of the lead 1b will not rise for tight contact with the frame placement stage 3. Since the tip end of the lead 1b is tightly contacted to the frame placement stage 3 with a simple structure, the ultrasonic wave vibration loss at wire bonding is eliminated for improved bonding quality.

Title: Socket for ic package
Inventor: KANESHIGE AKIRA
IPC: G01R31/26
Filed: 2000-06-17
Abstract: PURPOSE: A socket is provided for an IC package having a plurality of contacts. CONSTITUTION: A socket(1) includes a body(2) mounting a plurality of terminals and having a receptacle(3a) in the top thereof for receiving an IC package(24) with the contacts in engagement with the terminals. At least one retainer/ejector member is mounted on the socket body(2) adjacent the receptacle for movement relative to the body from a first position retaining an IC package(24) in the receptacle and a second position at least partially ejecting the IC package from the receptacle. An actuator member(12) is movably mounted on the socket body(2). The actuator member is operatively associated with the retainer/ejector member for moving the retainer/ejector member from its first position to its second position.

Abstract: PURPOSE: A region divide advertisement exposing method in a three-dimensional virtual space and an apparatus of the same are provided for fabricating and installing a certain target advertisement in an internet virtual space based on a request of a target advertisement owner built by a three-dimensional virtual technique and providing a detailed information of a target advertisement. CONSTITUTION: A main server(10) includes a database(50) for storing a target advertisement information therein and a VRML processing unit(60) which uses a three-dimensional virtual technique. A target advertisement owner(30) requests a target advertisement fabrication and storing to the main server(10) through the internet(20) and requests an update of the target advertisement for enhancing an advertising effect. A plurality of target users(41¯43) are accessed to the target advertisement after the main server(10) is connected through the internet(20).

Abstract: PURPOSE: A frying vessel with ultrasonic waves is provided, which increases the temperature of the oil in the pan quickly, so it takes short time to cook and which prevent the oil from being oxidized. CONSTITUTION: The frying vessel(301) equips an ultrasonic oscillator(M) on the outer wall to produce ultrasonic waves, a heating unit(305) under the vessel(301) to heat oil(303) in the vessel, a thermometer(307) to measure the temperature of the frying oil(303), and a control(309) to control the drive of the ultrasonic oscillator(M) based on the thermometer(307). In operation, the heater(305) keeps on heating to maintain the temperature of the oil(303) between 150-400 deg. C, and the ultrasonic oscillator(M) gives oscillation to the oil(303) at the frequency of 8khz-40khz to heat the oil.
