Abstract:
Disclosed is an apparatus for spinal column correction, which includes one or more spinal column correction units coupled and connected to each other. Each of the spinal column correction units includes a spinal column seating portion having a groove formed so that a user's spinal column is seated thereon; spinal column acupressure portions formed at left and right sides of the spinal column seating portion to be higher than the spinal column seating portion; a back seating portion formed to have a height lower than the spinal column acupressure portions and to have a height equal to or lower than left and right ends of the spinal column seating portion for user's back to be seated when the spinal column is seated; and a support portion for supporting the spinal column seating portion, the spinal column acupressure portion, and the back seating portion at a certain level.
Abstract:
A heating device having an improved heat resistance structure is provided. The heating device may include a heating element that generates heat, and an elastic conductive part that applies electricity to the heating element. A connector may be provided between the elastic conductive part and the heating element to preclude direct contact between the heating element and the elastic conductive part. The heating element may be fixed to one side of the connector, and the elastic conductive part may be fixed to the other side of the connector to allow current applied from the elastic conductive part to flow to the heating element.
Abstract:
The present invention relates to a cooker. In the present invention, a carbon heater is used to cook foods in a cooking chamber and electric current applied to the carbon heater is controlled by a switching element, such that an effective wavelength range and an available temperature range of energy generated from the carbon heater is adjusted. Therefore, according to the present invention, it is possible more efficiently cook foods, using the carbon heater.
Abstract:
A cooking appliance includes: an input part for inputting manipulations for cooking; a cooking grill formed with a controller for outputting a control signal according to the input from the input part and a grill section for contacting food; and a panel heater in the shape of a panel formed in the cooking grill to be controlled by the controller for supplying heat to the grill section, wherein the heat of the panel heater is transmitted concentratedly to the grill section of the cooking grill and the grill section is heated concentratedly so as to cook the food, thereby minimizing the loss of heat and making grill marks appear more clearly on the object.
Abstract:

Abstract:
Provided are a heater supporter and an electric hob including the heater supporter. A tube heater is supported by the heater supporter, and at least a portion of the heater supporter is formed of a ceramic containing material. Therefore, food can be cooked more rapidly, and the tube heater can be easily installed. Furthermore, damages caused by heat generated from the tube heater can be minimized.
Abstract:
A cooker and a controlling method for the same are provided. A carbon heater has a wavelength bandwidth of 1.5˜2.5 μm where a radiant energy is maximum, and the carbon heater provides the radiant energy into a cavity in order to heat food disposed therein.
Abstract:
A method for controlling packet service setup includes the steps of: transmitting a packet service request message containing a requested QoS to a packet service node by a mobile communication terminal; transmitting to the mobile communication terminal a packet service request response message including an assigned QoS determined in consideration of the requested QoS and network resources contained in the message received by the packet service node; comparing one or more parameter values among parameters contained in the assigned QoS contained in the packet service request response message from a mobile communication network with corresponding one or more parameter values among parameters contained in the QoS requested by the mobile communication terminal; and transmitting a packet service cancel request message if a difference between the parameter values is greater than or equal to a preset value.
