A system for detecting hazardous agents is based on cellular telephone networks. The cellular telephones in public circulation have at least one detector for detecting at least one hazardous agent and broadcast alarm packets upon detecting the hazardous agent. A computer or computer network interconnected with telephones by the cellular telephone network processes the alarm packets and sets an alarm condition for the hazardous agent in a vicinity of the cellular telephone by calculations based upon alarm packets from other telephones with detectors for the hazardous agent in the vicinity. A map of the contaminated area is also created.

A device for restraining the rise of a step roller of an escalator prevents the step roller from colliding with rails of a track in turn around areas at the top and bottom of the escalator. The device comprises: a supplementary roller, which is disposed between an outer rail and an inner rail of the track; an elastic member for biasing the supplementary roller toward the outer rail to roll thereon; and a supporting block to which the elastic member is fixed.

A liquid crystal display (LCD) device and its fabrication method are disclosed. Specifically, a fabrication method in which polyhedral spacers are implemented on a substrate through an ink jet method are used for an LCD device. The spacers have the polyhedral shape to increase their contact area with two substrates, and include a surface processed layer for strengthening a bonding force in its bonding with an alignment film formed on the two substrates. The spacers have a polyhedral shape for maintaining the cell gap between the substrates.

The present invention relates to an ultrasound diagnostic system and a method of forming arbitrary M-mode ultrasound images. The ultrasound diagnostic system includes: a probe for transmitting ultrasound signals toward a desired part of a target object and receiving the ultrasound signals reflected from the desired part; a scan converter for converting an ultrasound image data into a B-mode image data, the ultrasound image data being obtained based on the ultrasound signal received from the probe; an input unit for receiving an arbitrary M-mode scan line set by a user; an arbitrary M-mode processor for generating an arbitrary M-mode image data corresponding to the arbitrary M-mode scan line; and a display unit for displaying at least one of the B-mode image data, the M-mode image data and the arbitrary M-mode scan line. In accordance with the present invention, the biological information of the target object can be observed and diagnosed from an arbitrary direction and path, regardless of the direction of the ultrasound signals. Additionally, the arbitrary M-mode image, which is more similar to the real image, can be provided for the user by generating the arbitrary M-mode images corresponding to the arbitrary M-mode scan line by using ultrasound image data before scan-conversion.

A method for assigning a channel in multi-FA CDMA mobile communication system according to the received power prevents communication quality of a FA from being inferior to that of the others by managing the interference level of the FA. The method comprises the steps of: comparing a first threshold value with received power when the base station receives a new call request; assigning a traffic channel in a first FA of the request, if the received power is less than the first threshold value, and searching a second FA of which received power is least, if not; comparing a second threshold value with the received power of the second FA; and assigning a traffic channel in the second FA if the received power is less than the second threshold value, and rejecting the request, if not.

In the liquid crystal display panel of a horizontal electric field type, a gate pattern includes a gate electrode provided at a substrate, a gate line connected to the gate electrode and a lower gate pad electrode connected to the gate line. A data line is disposed to cross the gate line and the common line, having a gate insulating film therebetween to thereby define a pixel area. A thin film transistor is positioned at each intersection between the gate line and the data line. A transparent electrode pattern includes a pixel electrode electrically connected to the thin film transistor and disposed such that at least a portion thereof is parallel to the common electrode. An opaque conductive pattern is disposed to overlap with the transparent electrode pattern.
摘要:
A porous solid acid catalyst for producing light olefins is prepared through pillaring and a solid state reaction of a raw material mixture. The catalyst is made of a porous material having a crystalline structure that is different from that of the raw material mixture. The catalyst exhibits excellent catalytic activity (i.e., conversion and selectivity) in the production of light olefins from hydrocarbon feeds such as full range naphthas.
