Abstract:
The method of the present invention includes providing a silicon substrate having an impurity region, forming an inter-layer insulating film having a contact hole in the impurity region and forming a titanium film and titanium nitride film in the contact hole. The method of the present invention further includes conducting a heat treatment to cause a reaction between the titanium film and the silicon substrate and forming a tungsten plug on the titanium nitride film in the contact hole. The device of the present invention including the bit lines are made up of a first inter-layer insulating film on the substrate having a first contact hole over the impurity region, a titanium film in the first contact hole, a titanium nitride film on the titanium film, a titanium silicide film on the silicon substrate wherein the titanium silicide film does not include an agglomerate, a tungsten plug on the titanium nitride film in the first contact hole and a circuit element on the first inter-layer insulating film.
Abstract:
Provided is a pressure-balanced underwater acoustic transducer. The transducer includes an oscillator unit having an oscillator oscillating by an electrical signal supplied to electrodes, provided on its surface, a sound transmission material for transmitting sound from the oscillator, provided at its periphery, and a transducer housing provided at the exterior of the sound transmission material, a sound reflector positioned over the oscillator unit, for reflecting sound propagated from the oscillator, a water entry layer formed at a space between the oscillator unit and the sound reflector to allow water to enter and exit to the rear window of the oscillator, thereby leading to a balanced state of pressures applied to the front and rear windows of the oscillator, and a phase combiner for combining sound reflected from the sound reflector and straight traveling sound generated from the front window of the oscillator into one single phase. Therefore, the effect of underwater pressure on an oscillator is minimized, thereby manufacturing a highly reliable, cost-effective underwater acoustic transducer for deep sea. Also, even when the transducer is used for shallow sea, little deformation occurs over usage time.
Abstract:
Live strains of Lactobacillus acidophilus HY2177 and Lactobacillus casei HY2743 maintained in nutritious foods, such as yogurt, imbue them with prophylactic and/or therapeutic properties. Such foods are beneficial in the prevention and/or treatment of gastritis, duodenal and gastric ulcers caused by infection from Helicobacter pylori (also referred to as H. pylori). The properties of these bacteria are boosted by the addition of egg yolk containing antibodies specific to H. pylori antigen derived from “fractionated H. pylori” and may be administered as active strains alone in a food supplement, or the active strains may be combined with H. pylori-antibodies (IgY).
Abstract:
Disclosed is a multi-functional apparatus having a small size. The multi-functional apparatus according to the present invention includes a body including a section for transferring a recordable paper and a service station formed at an outside of the recordable paper transferring section; a guide mounted along an entire width of the body in a vertical direction to be normal to a recordable paper transferring direction; and a carriage which has a printhead and a scanner module mounted thereon and moves reciprocally along the guide to be across the recordable paper transferring section, the carriage being positioned in the service station when a scanning or printing operation is normally completed, wherein the scanner module is mounted on the carriage to be adjacent to the recordable paper transferring section with reference to the printhead.
Abstract:
A track traverse signal detecting apparatus and method adjust the level of a reference voltage by calculating a mean value of a track traverse signal, or by adjusting the frequency of the phase of the track traverse signal. The track traverse signal detecting apparatus and method further determine whether an optical medium being processed is a CD or a DVD, and adjust the level of a reference voltage based on this determination. Therefore, in the case of a track jump or random access, the track access operation is performed accurately.
Abstract:
A regulator circuit is provided for use with cell plate voltage generators of memory cell capacitors and precharge bit lines voltage generators in semiconductor memories. The circuit employs a current source coupled to the charging reference voltage whose output is controlled by a level detector, which receives as input a reference level signal and the cell plate voltage. When the cell plate voltage drops below the reference level, the level detector triggers the current source, thereby recovering the cell plate voltage to the reference level. The level detector can be disabled through an input.
Abstract:
A multiple loop antenna of a radio paging receiver comprising a first loop antenna, and a second loop antenna electrically connected to the first loop antenna, wherein the second loop antenna is positioned with respect to the first loop antenna to receive a radio wave travelling in a direction in which the receiving sensitivity of the first loop antenna is lowered.
Abstract:
A disk player which reproduces information recorded on a disk, includes a housing in the front of which an aperture is formed. A disk tray is installed to move into and out of the housing through the aperture and has an upper surface on which a disk is placed. A deck is installed under the disk tray in the housing. A turntable for rotating the disk and an optical pickup for reading information of the disk are installed on the deck. A mechanism is provided for lifting the deck while keeping the deck level. Thus, the disk can be positively clamped since a deck on which a turntable is installed ascends while keeping level.
Abstract:
Disclosed is a washing method which can eliminate suds or foam created in the course of washing by a washing machine and can effectively prevent the creation of foam, thereby improving the washing efficiency of the washing machine. In the washing method, a part of the washing liquid is continuously recirculated and sprayed during the washing process while the washing liquid is partially drained at each predetermined time interval. In the rinsing process, a part of the rinsing water is also continuously recirculated and sprayed during the rinsing process while the rinsing water is partially drained at each predetermined time interval.
Abstract:
An inexpensive rain water collecting device which is easy to manufacture. The rain water collecting device provides an effective device which is adaptable to various umbrella tip sizes and avoids any bacterial growth problems. The rain water collecting device includes at least a reservoir having a first open end and a second open end, the first open end has an opening with an inner perimeter which is substantially equal to an outer perimeter of the umbrella tip, and the second open end has an opening with a perimeter which is greater than the inner perimeter of the opening of the first open end; a ferrule formed about the opening of the first open end; and at least one flow barrier about the second open end of the reservoir. After using an umbrella in the rain, it is collapsed. The rain water on the cloth of the umbrella then drains into the reservoir of the rain water collecting device. The flow barrier(s) prevent the rain water contained in the reservoir from splashing out while the collapsed umbrella (although pointed substantially downward) is moved about.
