IPC: G11C11/41
Filed: 1995-05-22
Abstract: PURPOSE: To shorten the writing access time of a memory circuit by reducing the time constant related to the charging and discharge of a bit line in a writing cycle. CONSTITUTION: When a high level is given to a Din line and a high-level signal is given to a word line connected to a row selecting line 229 for writing '1' in a memory cell, a specific memory cell in a memory array becomes usable. When the memory cell becomes usable, output nodes 266 and 268 are set at low signal levels. The low signal levels generate a high signal level in a nose 296 and a low signal level in another node 292. When the signal level of a row selecting line 299 becomes higher, CMS transfer gates 226 and 228 are turned on and the node on a bit line 222 becomes a high logic level, and then, a bit line 220 becomes a low logic level. Therefore, an MOS-SRAM cell remains in a logic '1' state.

IPC: H01L21/20
Filed: 1997-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a silicon film which has excellent crystallinity and in which the growing direction of crystals is controlled. SOLUTION: A metallic element (e.g. nickel element) which selectively promotes crystallization is introduced to an amorphous silicon film formed on a glass substrate. Then the silicon film is heated so that the metallic element can promote the growth of crystals in the direction parallel to the substrate from the introduced area of the element. The crystals are grown in the (111)-axis direction. In the (111)-axis direction, the silicon film has lower conductivity as compared with the other direction. When a device is constituted so that carriers can move in the crystal growing direction, the electric characteristics of the device can be improved.

Filed: 1988-05-19
Abstract: PURPOSE:To prevent the random winding of a wire rope by judging the inclination direction of a bucket based on the inclination of the bucket supporting wire rope, moving a crane, and winding the wire rope in the vertical state in the crane with the bucket. CONSTITUTION:When a bucket is lowered, if a wire rope is further unwound after the bucket reaches the floor, the bucket is inclined. A bucket supporting wire rope W1 is also inclined by this inclination, a weight 10 is inclined by the inclination of this rope W1, thus an inclination detecting lever 8 is inclined after the inclination direction of the wire rope W1 via inclination detecting wires 91 and 92 connected to this weight 10. When this detecting lever 8 is moved, the inclination direction and angle are detected by an angle detector 7 connected to its rotary shaft. A crane is moved in the inclination direction of the bucket based on the detection quantity so that the angle of the wire rope W1 is made nearly vertical, i.e., no random winding of the wire rope W1 occurs.
