Abstract:
A magnetron is provided including a yoke having an inner space; a first magnet provided at one end of the inner space, a second magnet provided at a second end of the inner space, the second magnet being axially spaced from the first magnet. Further, there is an anode cylinder that generates a high frequency provided between the first magnet and the second magnet; a first pole piece and a second pole piece provided proximate first and second openings of the anode cylinder, respectively. Additionally, a seal that prevents outward leakage and has an inward protrusion extending axially toward the anode cylinder; and a choke filter, provided beneath a free end of the inwardly bent end of the seal to prevent outward leakage, may be provided.
Abstract:
A screen for a projection display is provided. The screen includes a Fresnel lens sheet which converges light emitted from a light source, and a lenticular lens sheet which disperses in a horizontal direction the light transmitted by the Fresnel lens sheet. The Fresnel lens sheet includes a first Fresnel lens on one surface and a second Fresnel lens on an opposite surface.
Abstract:
DLL integrated circuits include least one delay element associated with the generation of an internal clock signal and a control circuit that is configured to periodically adjust a delay of said at least one delay element in response to a first clock signal (CLK). The control circuit is further configured to block at least one periodic adjustment of the delay of the at least one delay element in response to detecting excessive jitter with CLK. This DLL may be configured to block at least one periodic adjustment to a phase of an internal clock signal (ICLK) in response to detecting an excessive phase difference between the first clock signal (CLK) and a feedback clock signal (FCLK) derived from the internal clock signal (ICLK).
Abstract:
A method for determining traffic conditions comprises: collecting real-time traffic information of a road; calculating a representative speed value for the road by a fuzzy inference, from the collected real-time traffic information and traffic condition factors having an effect on the road; and transmitting the representative speed value to a terminal of a vehicle traveling on the road corresponding to the representative speed value. The representative speed is sensibly determined and reliable information is supplied because the fuzzy inference's performance is based on the information collected from the signal transmitter and based on the factors which can affect the traffic conditions.
Abstract:
Duty cycle correcting circuits having a gain adjusting circuit that selects one of a plurality of gains of the duty cycle correcting circuit based on a frequency of an input signal. An output circuit outputs a duty cycle corrected output signal based on the input signal and the selected one of the plurality of gains. The input signal may be an input clock signal and the output signal may be a corrected clock signal. Methods are also provided.
Abstract:
A system and method for managing information of a mobile terminal automatically generates a link to related information in association with one or more separate function databases in the mobile terminal. All information stored in each function database is also stored in a link database to allow other functions to refer to them. When a certain function is used, its related information is automatically searched for in the link database. If related information exists, a hyperlink to the related information is automatically generated, so that a user can simply use the related information as necessary.
Abstract:
Disclosed is a tooth-cleaning paper combined with dental floss, in which the tooth-cleaning paper is formed of a thin paper or a gauze sterilized and wetted with an aqueous fluoride solution and has a plurality of edge cuts formed along an edge of the tooth-cleaning paper, and the dental floss is provided in a single strand or two strands along a margin of the tooth-cleaning paper to be fixed to the tooth-cleaning paper and has an exposed dental floss part formed by each of the plurality of edge cuts of the tooth-cleaning paper. The tooth-cleaning paper of the current invention is advantageous in terms of easily cleaning the teeth and interdental portions of users while not offending other persons at any time and in any place.
Abstract:
Integrated circuit devices and methods of operating same include a delayed locked loop (DLL) circuit that can be operated at a high frequency during a normal operation mode and during a test mode. The test mode may be, for example, for performing burn-in testing. For example, an integrated circuit device may include a DLL control circuit that generates a control signal that is responsive to a test mode signal. An oscillator circuit may generate a clock signal that is responsive to the test mode signal. This clock signal may be a high frequency clock signal, such as that used to drive a DLL circuit during a normal operation mode. A DLL circuit, which is responsive to the clock signal, may be configured to operate in either a test mode or a normal operation mode based on the control signal. By generating the clock signal at a high frequency, the DLL circuit may be evaluated during burn-in testing, for example, under conditions that are comparable to conditions during normal operation.
Abstract:
The present invention is based upon the discovery that the methanol extract of the bryozoan Myriapora truncata showed potent cytotoxicity against L1210 murine leukemia cells (99% inhibition at 50 .mu.g/mL). Fractionation and purification of active components from this extract, guided by a cytotoxicity assay, resulted in the isolation of a novel, highly cytotoxic polyketide-derived metabolite MT-332 (Compound 3) and its equilibrium isomer (Compound 4), along with two less active compounds, MT-381 (Compound 1) and MT-381-B (Compound 2). The equilibrium mixture of Compounds 3 and 4 showed 88% inhibition at 0.2 .mu.g/mL against L1210 cells. ##STR1##
