Abstract: A semiconductor memory device comprises a substrate, a first conductive line extending in a first direction on the substrate, a second conductive line extending in a second direction on the first conductive line, a memory cell between the first and the second conductive lines, and a spacer covering a part of a side wall of the memory cell, wherein the memory cell includes a first electrode connected to the first conductive line, a second electrode connected to the second conductive line, and an information storage pattern between the first and second electrodes, wherein the spacer covers a side wall of the information storage pattern and a side wall of the second electrode, but not side walls of the first electrode, and the first electrode is wider than the information storage pattern at a portion on which the first electrode and the information storage pattern contact to each other.

Abstract: A tie clamp includes: a clamp body formed by bending an elastic metal material having a relatively long length as compared to the width thereof in a circular shape; a male restrainer and a female restrainer formed at the opposite end sides of the clamp body to restrain an object to be restrained; and an ear formed on each of the male restrainer and the female restrainer so that a tool can be used to reduce the diameter of the clamp body to turn the clamp body into a restraint state.

Abstract: Disclosed is a torque control bolt for a hose clamp, which is configured to transmit a torque from a tool to a fastening bolt of a hose clamp to induce the fastening of the hose clamp, and then to be ruptured to prevent the transmission of torque exceeding a set value so as to prevent the damage of the hose clamp and the hose. The control bolt includes: a rupture bolt with a fastening body to transmit the torque from the tool to a head of the fastening bolt; a coupling unit formed on the head and the rupture bolt and configured to keep the coupling force between the head and the rupture bolt; and a rupture section formed on the rupture bolt and configured to prevent the torque from the tool from being transmitted to the fastening bolt when the torque exceeds the set value.

Abstract: A hose clamp includes: a clamp body having a plurality of screw holes passing therethrough; a coupling housing disposed at one side of the clamp body and into which an opposite side of the clamp body is inserted; and a coupling screw rotatably disposed in the coupling housing and engaged with the screw holes of the clamp body inserted within the coupling housing, wherein the clamp body includes a compensating means including at least one compensation bead formed at one side of the clamp body for resiliently fastening a hose by a degree by which a diameter of the hose is decreased so as to firmly tighten the hose. The hose clamp can prevent the compensation means from being deformed over the resilient area, so that the compensation means is not deformed over the resilient area.

Abstract: A display device is provided that includes a light source for emitting a light, an image forming unit for forming an image using the emitted light and an inputted image signal, and a projection lens for projecting the formed image on a screen. The display device may further include an actuator for shifting the image displayed on the screen, a temperature sensor for detecting an ambient temperature around the actuator, and a controller for driving the actuator according to the detected temperature.

Abstract: A composition and method of use for the treatment of pain and inflammation associated with dental disease is disclosed. The composition comprises pine resin and salt in a 1:1-5 parts by weight relationship which is prepared by mixing the pine resin and salt, heating the mixture while stirring, cooling and grinding the resulting solid to a powder form.
