Title: Semiconductor memory capable of high-speed word line driving
Inventor: JO TOICHI
IPC: G11C29/04
Filed: 1994-04-06
Abstract: PURPOSE: To get rid of malfunction of word line selection based on a glitch phenomenon of a redundant enable signal by facilitating enable timing adjustment of drive voltage which supplies as power source of the word line in a semiconductor memory device. CONSTITUTION: A great feature in a word line drive system is that a normal word line decoder 100E and a spare word line decoder 100G are operated independently of a signal ϕXE. Thereby, a data access speed is increased, a signal ϕXEX can be eliminated and acquiring an enable point of a signal ϕX is accelerated. When a memory device is operated, drive voltage OX which supplies as power source of a word line is enable with the signal ϕXE and by this, the device gets in an operation state. Thus, the circuit configuration on timing adjustment about a word line drive signal becomes unnecessary and the drive voltage can be supplied to the decoder 100E or the decoder 100G.

IPC: G01N3/32
Filed: 1994-03-16
Abstract: PURPOSE:To provide a method for evaluating the sensitivity of a steel pipe material to circumferential crack occurring in a boiler steel pipe. CONSTITUTION:In a simulation environment where a boiler steel pipe is used, a test piece is subjected to repetitive distortion thus causing crack in the circumferential direction similarly to that occurring in an actual boiler. Assuming the interval of circumferential crack is D and the distortion being applied is epsilon, epsilonC and lr/c in a formula D=lr/cdivided by (epsilon-epsilonc) are determined and then epsiloncr in a formula epsiloncr=epsilonc+(lr/cdivided by Dr) is determined using the length Dr of actual material. This method can evaluate the circumferential crack resistance of a material employed in a test piece of boiler steel pipe and can evaluate the circumferential crack sensitivity of the material using the limit distortion epsilonc or epsiloncr.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To eliminate fluctuation of autofocusing and to obtain a good picture by making the direction of traversing a track image generated on a sensor coincident with the direction of traversing a dividing line of a quadripartite sensor when a light spot traverses a track. SOLUTION: When an objective lens 27 traverses a track, reflected flux from an optical card 1 is moved in the direction of X. At this time, the track image to move on the sensor 30 is moved in accordance with expressions as shown in the figure, which are decided by operating coeffts. of a spherical lens 28 and a cylindrical lens 29 and an angle α of a generating line of the cylindrical lens with a track. Now, when focal distances of the individual lenses and a distance between the spherical lens 28 and the sensor 30 are specified and the calculation is performed, an angle θ formed by the moving direction of a track on the sensor 30 with a Y-axis is θ=α.  By deciding the shape of the sensor in accordance with this result, even when the objective lens 27 traverses the track, the moving direction of the track image can be made to coincide with the quadripartite lines.
