Abstract: A display device includes a display portion including a first surface, from which light is emitted in a first direction, and a second surface opposite to the first surface, a first optical portion disposed on the first surface, and a second optical portion disposed on the first surface to be spaced apart from the first optical portion in a second direction crossing the first direction. Each of the first and second optical portions includes a multi-channel lens through which the light from the first surface passes, a first infrared light source, a first camera, and a first lens frame coupled to the multi-channel lens in the first direction to support at least a portion of the multi-channel lens. The first lens frame may include a first recess structure in which the first infrared light source is disposed and a second recess structure in which the first camera is disposed.

Abstract: To enable a user to cook both in a pressure state and in a non-pressure state inside the inner pot and thus improve cooking quality and ease of use, the present invention provides an electric cooker including a main body in which an inner pot for accommodating food is installed; a lid coupled to the main body to be opened or closed, in which a passthrough portion is formed; a pressure converter communicating with the passthrough portion, in which a selectively opened/closed state for discharging steam inside the inner pot is maintained; and a pressure-responsive actuators communicating with the passthrough portion and selectively opened/closed depending on a pressure level inside the inner pot in a pressure cooking mode.

Abstract: An electric cooker is configured to cook in a pressure state and a non-pressure state of an inner pot, thereby improving the cooking quality and convenience of use.

Abstract: An electric cooker is configured to cook in a pressure state and a non-pressure state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body configured to accommodate an inner pot; a lid coupled to an upper portion of the main body and having a handle portion provided at one side of an upper portion of the lid to interwork with an inner pot locking unit configured to lock the inner pot; a pressure switching unit arranged to pass through the lid and configured to switch or maintain an opened or closed state to discharge internal steam from the inner pot according to a rotation of the handle portion; and a pressure-responsive operating unit which is selectively opened or closed according to a pressure inside the inner pot in a pressure cooking mode in which the pressure switching unit is closed.

Abstract: A high bulky wool spun yarn for knitting or weaving, which has high bulky properties formed by bulky loops in the bundle of the yarn, and a drafting system for making the same is provided. The drafting system includes a spinning machine with an improved front top roller that periodically changes the contacting points of a wool roving to form uniform bulky loops in a bundle of a wool spun yarn, thereby forming the high bulky wool spun yarn. Multiple grooves which are perpendicular to the axis of the top roller are formed on the surface of the top roller. Additionally, multiple slanting grooves which are slanted at about 45.degree. to the axis of the top roller or to the multiple grooves are formed on the surface of the top roller. Abrasion resistant fillers are inserted and fixed in the multiple slanting grooves.
