摘要:
A cooking apparatus is provided that has an oven cooker and a cook-top cooker. Heat is radiated through a ventilation structure formed by an air inflow duct and an air discharge duct. Additionally, the air inflow duct and the air discharge duct may be stacked one on top of the other, and provided between the oven cooker and the cook-top cooker. Further, the air discharge duct is configured to communicate with an outside, e.g., via a blowing fan unit and an air guide. Further, a cooling capacity can be greatly improved by performing an optimal compulsory cooling according to an operation mode.

A method and apparatus for non-invasively determining the concentration of a substance in blood, such as glucose, include a sample portion arranged for contacting an eye region of a user to obtain a tear fluid sample, a sensor in communication with the sample portion for generating a signal related to the tear substance concentration, and a processor in communication with the sensor for determining a blood substance concentration corresponding to the tear substance concentration.

A cooking device includes a cabinet, a cavity installed in the cabinet and having a cooking chamber therein, a door installed at the cabinet to open and close the cooking chamber, a ventilation passage formed to allow external air of the cabinet to pass through between the cavity and the cabinet so as to be discharged, a blower installed in the ventilation passage, and a cooking chamber air discharge unit for discharging air from the interior of the cooking chamber through the ventilation passage. Because the heated air inside the cooking chamber can be cooled by air which passes through the ventilation passage and then discharged, when the door is opened, heated air cannot be directly discharged to a user from the cooking chamber.

There is provided an ultrasound diagnostic system adapted to provide an elastic image with additional information. The ultrasound diagnostic system comprises: a probe for receiving echo signals from a target object, the probe being configured to transfer a pressure applied by an user to the target object; an elastic image processor for producing an elastic image and an additional information related thereto based on each of the echo signals before and after applying the pressure; and a display for displaying the elastic image and the additional information, which are inputted from the elastic image processor. The additional information includes an elastic image map and a strain ratio of a medium. The elastic image processor calculates the strain ratio based on the echo signals before and after applying the pressure and calculates a constriction speed based on the strain ratio and the frame rate, the elastic image processor being configured to form an elastic image map showing a relationship between the constriction speed and the strain ratio.
摘要:
A manufacturing method of a polyurethane foam injected with strand mats and a device for increasing the volume of the strand mats. The method comprises the steps of: increasing the volume of each of the strand mats to weaken the cohesion between glass fibers in each of the strand mats; continuously supplying and transferring the volume-increased strand mats; spraying a polyurethane foam solution on the continuously transferred strand mats; and foam molding the polyurethane foam solution in which the strand mats are immersed, into a polyurethane foam. Because the cohesion between the glass fibers in the strand mat is weakened and the volume of the strand mat is increased, the polyurethane foam solution uniformly permeates into the strand mats. As a result, the productivity of the polyurethane foam is improved and the variations in a variety of the mechanical properties are minimized.
摘要:
A method and an apparatus for manufacturing a polyurethane foam injected with strand mats. After a polyurethane foam solution is sprayed on the strand mats, the strand mats are moved upward and downward by prominences and depressions and then intermittently pressed by a pressing device, thereby the air in the strand mats being exhausted to the outside. Therefore, the polyurethane foam solution uniformly permeates into the strand mats. As a result, the insulating effect and mechanical strength of the polyurethane foam are increased, uniform surface with no air spaces is obtained, the mechanical properties are made uniform, and shrinkage, cracking, distortion and the like are prevented under a super-low temperature such as less than −165° C.
