Abstract: A multi-purpose cooking vessel and a method of manufacturing the vessel are provided. The vessel includes: a body having a concave shape; and a handle attached to the body. The body includes: a flat bottom plate; and a sidewall formed on the circumference of the bottom plate. The sidewall includes: a lower sidewall which is formed from the circumference of the bottom plate and is extended upwardly and rounded externally; and an upper sidewall which is extended upwardly from the top of the lower sidewall and bent rounded internally toward inside of the body. The top edge is inclined such that the height of the upper sidewall gradually increases from a first side of the body toward a second side of the body located opposite to the first side. An opening portion of the top of the sidewall is formed to have a circle shape.

Abstract: An engine-generator comprises: a generator 13, an internal combustion engine 14 coupled to the generator 13 such that operation of the internal combustion engine 14 will generate electricity via the generator 13, and a control system incorporating a misfire detection system 5, the misfire detection system 5 being arranged to monitor engine rotation speed in order to detect a misfire event during operation of the engine 1; wherein in response to an indication of the misfire event the control system initiates a safety mode of the engine-generator.

Abstract: A wiper blade packing case including a plate-type lower panel; a plate-type upper panel; and a pair of covers, each of which has an elliptical cross-sectional surface corresponding to the cross-sectional surface of the receiving portion, and each of which is bent and extends from each of the shorter sides of the upper panel to close openings formed at both sides of the receiving portion.

Abstract: A crystallized glass with negative coefficient of thermal expansion includes 38 wt % to 64 wt % of silica (SiO2); 30 wt % to 40 wt % of alumina (Al2O3); and 5 wt % to 12 wt % of lithium oxide (Li2O) as a basic component, and further includes more than one component selected from the group consisting of 0.5 wt % to 15 wt % of zirconia (ZrO2), 0.5 wt % to 6.5 wt % of titanium dioxide (TiO2), 0.5 wt % to 4 wt % of phosphorus pentoxide (P2O5), 2 wt % to 5 wt % of magnesium oxide (MgO), and 0 wt % to 5 wt % of magnesium fluoride (MgF2) in addition to the basic components. The crystallized glass may have a high negative coefficient of thermal expansion so that it has an advantage that it can be used as a thermal expansion compensation material according to the temperatures of all kinds of glasses and similar products thereof.

Abstract: The present invention relates to a wiper blade packing case for packing a vehicle wiper blade.

Abstract: A backpack assembly includes a luggage case having a first attachment interface and a backpack having a second attachment interface. The second attachment interface is configured to be mated with the first attachment interface to removably attach the backpack to the luggage case. The luggage case further includes a flap with a third attachment interface that is configured to be mated with the first attachment interface if the backpack is detached from the luggage case.

Abstract: The present invention relates to a switching system, and in particular to a path management method for a switching system which is capable of periodically checking a path state of each hardware board in a switching system of a dual active structure, managing the checked state based on a database, so that an operator recognizes a change in the states of the hardware boards. In addition, the present invention provided a standby path capable of searching an actual active path at the current point based on the database. A path test method for a switching system is provided for thereby implementing a path test for an entire interval or a certain interval with respect to the active and standby paths. Therefore, in the present invention, it is possible to enhance a continuity and reliability of a service and implement an easier maintenance of the system.

Abstract: An apparatus for a refresh and a data input device in the SRAM having a storage capacitor cell comprises an internal clock generator for generating and outputting two internal clock signals having a certain time difference of each other, a refresh timer for generating and outputting an output signal to notify a refresh time, a refresh signal generator for generating a refresh signal in response to a faster signal of the two internal signals and the output signal from the refresh timer, a refresh counter for generating refresh addresses during the refresh and a column path controller for controlling the activation of a column path in response to a row active signal and the refresh signal.

Abstract: The arrangement of the moleculars of the optical activity compound such as polymer including azo-dye is changed by the polarization state of the pump beam applied to the polymer. The polymer is polyvinyl alcohol including methyl orange as azo-dye. The anisotropy of the molecular arrangement of the azo-dye is induced by the polarized incident beam and then the liquid crystal cell is made. Thereafter, the liquid crystal is inserted to the cell, aligning the liquid crystal.

Abstract: A mobile detection system for detecting a fire, gas leak, intruder, or other abnormal condition in a house or an office, and for alerting a central monitor, fire station, police station, or an occupant who is away from the house or office. The mobile detection system comprises a self-propelled movable robot having sensors located thereon. A monitor receives signals from the robot and alerts an authorized user accordingly. An automatic communication control unit includes a telephone transmitting unit for automatically calling an appropriate party in response to a signal from the robot and transmits commands to the robot from an authorized calling party. A radio frequency remote controller for remotely controls the robot. The robot is specifically capable of navigating throughout a house or an office while using its sensors to detect abnormal conditions.

Abstract: A self-propelled robot has a robot body on which a drive wheel is mounted. The drive wheel is connected to a member that can be turned about a vertical axis for steering the robot. A propulsion drive mechanism is mounted on that member for transmitting a propulsion drive to the drive wheel. The propulsion drive mechanism includes a clutch mechanism for disengaging the propulsion drive when the drive wheel encounters excessive resistance to travel. The clutch mechanism includes a spring biased clutch element mounted on an internal spline shaft of the drive wheel.
