A cosmetic device comprises a support member; a cap member attached to the support member and having a front face; a vibration actuator disposed inside the cap member, which produces vibration for providing massage effect on a skin; and an uneven surface member as an outermost layer covering at least the front face of the cap member. The uneven surface is configured to prevent denudation of a treatment agent applied on the skin.

A plate member (10) is mounted on a supporting frame (11). The periphery of the plate member (10) is firmly secured by a clamp (12) and a concave die-shaped lower pushing member (13) is caused to rise from below. The lower pushing member (13) is provided with a forming concave area (15) and a forming convex area (16). Disposed above the plate member (10) is a bar-shaped upper pushing member (20) which is lowered to push against the plate member (10). In such a condition, the plate member (10) is caused to rise together with the lower pushing member (13) and move in the directions of X and Y to form convex areas (17) and (18) within the forming concave area (15) and the forming convex area (16). The upper pushing member (20) is provided with a main body (21) of high rigidity and a flexible member (22). The flexible member (22) is formed in a hemispherical shape and made of material more elastic than the main body (21) which is made of hard polyurethane or the like, thereby making spherical contact with the plate member (10).

A dispenser of a conventional refrigerator supplies only cold water. Therefore, the dispenser cannot meet a variety of users' needs. Further, the conventional refrigerator has a problem in that various kinds of water supplied from a water source cannot be properly purified. The present invention relates to a refrigerator including a main body with a storage space defined therein and a door for opening and closing the storage space. The refrigerator of the present invention comprises a feed tube for guiding water, which is supplied from an external water source to the main body of the refrigerator, to the door; a valve for distributing the water supplied from the feed tube into a plurality of connection tubes; a cooling tank installed within the door for cooling the water supplied through the valve and then storing the cooled water therein; a heater installed within the door for receiving the water supplied through the valve separately from the cooling tank and then heating the received water; and a dispenser for dispensing the hot and cold water supplied from the heater and cooling tank to the outside of the refrigerator through a front surface of the door. The refrigerator further comprises a filter for filtering the water, and the filter is provided at one of the feed tube and connection tubes for supplying the water toward the heater and detachably installed in the storage space defined in the main body of the refrigerator.

Low-profile spindle motor whose entire shaft length is utilized to configure, along an encompassing sleeve, a radial dynamic-pressure bearing section. One end of the shaft is unitary with the rotor, and a cover member closes the other end. Between the sleeve upper-end face and the rotor undersurface a thrust bearing section is configured. Micro-gaps are formed continuing between the sleeve upper-end face and the rotor undersurface; the sleeve inner-circumferential surface and the shaft outer-circumferential surface; and the cover member inner face and the shaft end face, where an axial support section is established. Oil continuously fills the micro-gaps, configuring a full-fill hydrodynamic bearing structure. Hydrodynamic pressure-generating grooves in the radial bearing section are configured either so that no axial flow, or so that a unidirectional flow that recirculates from one to the other axial end of the radial bearing section through a communicating pathway is induced in the oil.

In a photoelectric conversion device, in a contact between a p-type semiconductor 3a and an electrode 2, an n-type semiconductor 6 of a conductivity type opposite to that of the p-type semiconductor is provided between the p-type semiconductor 3a and the electrode 2. The existence of the n-type semiconductor 6 allows a recombination rate of photo-generated carriers excited by incident light to be effectively reduced, and allows a dark current component to be effectively prevented from being produced. Therefore, it is possible to improve photoelectric conversion efficiency as well as to stabilize characteristics. Further, a tunnel junction is realized by increasing the concentration of a doping element in at least one or preferably both of the p-type semiconductor 3a and the n-type semiconductor 6 in a region where they are in contact with each other, thereby keeping ohmic characteristics between the semiconductor and the electrode good.

To provide a liquid crystal display apparatus exhibiting optimum display performance despite reduction in the number of PR(photolithography) processes, and a method for producing the apparatus. A method for producing a liquid crystal display apparatus having a first substrate including a thin film transistor and a reflector on an insulating substrate. An etching mask is formed on a metal layer formed on the insulating substrate and, using this etching mask, the metal layer is etched to form a constituent portion of the thin film transistor and protrusions. Only the etching mask is caused to reflow to cover exposed surface portions of the constituent portion of the thin film transistor and protrusions and near-by surface portions of the insulating substrate with the etching mask as the insulating substrate is partially exposed. Using the etching mask, recesses are formed in an exposed area of the insulating substrate. A reflector is formed on the protrusions and recesses.

A field emission display device and a method of fabricating the same are provided. The field emission display device includes a substrate, a transparent cathode layer, an insulation layer, a gate electrode, a resistance layer, and carbon nanotubes. The transparent cathode layer is deposited on the substrate. The insulation layer is formed on the cathode layer and has a well exposing the cathode layer. The gate electrode is formed on the insulation layer and has an opening corresponding to the well. The resistance layer is formed to surround the surface of the gate electrode and the inner walls of the opening and the well so as to block ultraviolet rays. The carbon nanotube field emitting source is positioned on the exposed cathode layer. An alignment error between the gate electrode and the cathode is removed, and carbon nanotube paste is prevented from remaining during development, thereby preventing current leakage and short circuit between the electrodes and diode emission. Accordingly, the performance of the field emission display device can be improved.
