Title: Semiconductor memory device
Inventor: MATSUZAKI YASUROU
IPC: H01L27/04
Filed: 1983-12-27
Abstract: PURPOSE:To enable to reduce the wiring capacity of the titled device and to perform the readout operation of the device at higher speeds by a method wherein wirings, by which a first multiplexer and an output buffer are mutually connected, and wirings, by which a second multiplexer and the output buffer are mutually connected, are provided. CONSTITUTION:There are eight wires of wirings between the terminals Mn (n=1...8) of a multiplexer 3 and the terminals Bn(n=1...8) of an output buffer 4. The half of the terminals Mn of the multiplexer 3, which have been connected to 4 wires of wirings equal to the half of the eight wires of wirings and have been provided on the side of the output buffer 4, are disposed on the opposite side of a memory cell region 7 to the half terminals of the multiplexer 3. A part of a current distributor 2 inclusive of terminals Dn(n=1...4), which had been ever disposed at the positions of the half terminals of the multiplexer 3, is disposed on the opposite side of the memory cell region 7 to the terminals Dn and near the remaining part of the current distributor 2 inclusive of the terminal Mn (n=5...8) of the multiplexer 3. By this chip layout, the wiring between the terminal M1 of the multiplexer 3 and the terminal B1 of the output buffer 4, whose length had been ever the longest and whose wiring capacity had been also the largest, is shortened. As a result, a reduction of the wiring capacity of the semiconductor memory device is contrived and the readout operation thereof can be performed at higher speeds.

Filed: 1986-10-22
Abstract: PURPOSE:To detect the minute change of the means value with high sensitivity despite the unfixed fluctuation trend and large variance, by obtained the allowance limit of the cumulative deviation value obtained from a corresponding time point every time the time point when the means value of the processing result is changed from the control center value and then deciding whether the latest cumulative deviation value is set within the allowance limit or not. CONSTITUTION:A cumulative sum arithmetic means 100A obtains a cumulative sum st of deviations of the wafer processing result xt and the control center value (k) as well as the cumulative data number (t). A fluctuation start time point detecting arithmetic means 100B detects a time point when the means value of the result xt is changed from the value (k). A fluctuation detecting arithmetic means 100C decided whether the sum st is set within its allowance limit or not at the latest time point. Thus the change of the mean value of the xt from the value (k) is detected. A display means 100D plotted the st into a time series and displays the time points when the means value of the xt is changed from the value (k) and when the fluctuation is detected on a 2nd computing element 113 and a display device 114.

Title: Magneto-optical recording medium and its production
Inventor: IKETANI NAOYASU
IPC: G11B11/105
Filed: 1994-10-14
Abstract: PURPOSE:To obtain reproducing signals of high qualities while hardly changing the laser power required for reproducing. CONSTITUTION:This magneto-optical recording medium has a read-out layer 3 and a recording layer 4 in which information is magneto-optically recorded on a transparent substrate 1. The read-out layer 3 shows intraplane magnetization with superior intraplane magnetic anisotropy at room temp., while perpendicular magnetization with superior perpendicular magnetic anisotropy gradually appears with increase of temp. The compsn. of the read-out layer 3 varies in the film thickness direction and the layer has higher Co concn. in the side where light enters than in the side of the interface with the recording layer. Since the Curie temp. of the read-out layer 3 in the side where the reproducing light enters is higher, the polar Kerr rotation angle increases during reproducing, which improves qualities of reproducing signals. On the other hand, since the Curie temp. in the interface of the layer 3 with the recording layer 4 is low, shift of the threshold temp. from intraplane magnetization to perpendicular magnetization to a higher temp. due to the magnetic interaction with the recording layer 4 can be suppressed to a small degree.

Title: IMPROVED PROCESS FOR PRODUCTION OF LINEAR alpha-OLEFIN WITH SUPERCRITICAL ETHYLENE RECYCLE
Inventor: PAUL A SEKKURISUTO
IPC: C07C11/02
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the amount of compression required for unconverted ethylene by carrying out separation and recycle of supercritical ethylene in oligomerization of the ethylene. SOLUTION: A linear α-olefin is continuously produced by oligomerizing the ethylene in a polar phase containing a transition metal catalyst system under oligomerizing conditions including a temperature and a pressure greater than the critical temperature and pressure of ethylene. The resultant hydrocarbon phase containing hydrocarbons and unconverted ethylene is subjected to physical treatment which tends to render the ethylene a nonsolvent for oligomers to thereby produce a liquefied stream rich in supercritical ethylene which can be recycled to the oligomerization reactional zone by pumping.

Filed: 1987-10-06
Abstract: PURPOSE:To prevent offensive sounds such as sliding and hammering noises caused by a spiral cable by providing a curvilinear part greater than the thickness of the spiral cable in at least one edge part of the tape-form spiral cable. CONSTITUTION:A spiral cable 17 is formed in a tape form, and is provided with curvilinear parts 17a in both edge parts.
