Title: Method for catalytically hydrating olefin
Inventor: INOUE KAORU
IPC: C07B61/00
Filed: 1994-11-29
Abstract: PURPOSE: To obtain alcohols at a high efficiency in liquid phase by catalytically hydrating an olefin using a heteropoly-acid as a catalyst. CONSTITUTION: An olefin which is an aliphatic hydrocarbon compound having at least one or more carbon-carbon double bonds (e.g. ethylene or propylene) is catalytically hydrated by using a heteropoly-acid dispersed in an organic polymeric siloxane having a hydrocarbon group as a catalyst under conditions of water present in a liquid state at 0-500 deg.C under 0.5-500atm to afford alcohols. The stable catalyst having high activities without elimination and decomposition of acidic substances by the thermal decomposition of the catalyst which are disadvantages of a conventional solid heterogenous catalyst is obtained by using the heteropoly-acid as the catalyst and the deterioration in the activities of the catalyst due to the presence of water in the reactional system is further suppressed.  The alcohols can be produced by directly hydrating the olefin even under low-temperature and low-pressure conditions according to this method. In addition, there is no fear of corroding reactional apparatuses, etc.

Title: Digital distance relay
Inventor: TAKANI HIDEYUKI
IPC: H02H3/40
Filed: 1994-11-30
Abstract: PURPOSE: To let a measured distance value show an under-reach tendency and prevent unwanted operations due to over-reach by subtracting a constant from a denominator of a reactance calculating formula wherein voltage and current of a power system are used when a sign of the denominator is positive and adding the constant to the denominator when the sign of the denominator is negative. CONSTITUTION: When voltages and currents to be applied to a distance relay at different sampling times 'm' and 'm-n' are Vm , Vm-n and Im , Im-n respectively, a numerator of a reactance calculated by a reactance numerator calculating means 2 for the times 'm' and 'm-n' is expressed by a formula UL=im .Vm-n -im-n .Vm and a denominator of the reactance calculated by a reactance denominator calculating means 3 is expressed by U=im .jm-n -im-n .jm . In this case, when a sign of the denominator U is positive, a reactance denominator correcting means 4 subtracts a constant IN<2> from the denominator and a corrected value U'=U-IN<2> is obtained and when a sign of the denominator U is negative, the reactance denominator correcting means 4 adds the constant IN<2> to the denominator U and then a corrected value U+IN<2> is obtained.  By this method, a measured distance shows an under-reach tendency and thereby unwanted operations due to over-reach can be prevented.

Title: Y/c separating circuit for video signal
Inventor: KURISAKI KAZUHIRO
IPC: H04N9/78
Filed: 1991-11-12
Abstract: PURPOSE:To suppress a dot disturbance of a horizontal non-correlation part of a color signal, and to improve oblique resolution of a luminance signal by separating a video signal into a luminance signal and a color signal, amplifying a high frequency component extracted from the color signal and adding it to the luminance signal. CONSTITUTION:A video signal is separated into a luminance signal and a color signal by utilizing its vertical correlation. A band elimination filter BEEF 10 extracts a high frequency component of the color signal, and a detecting circuit 11 detects a degree of saturation of the color signal. Subsequently, the extracted high frequency component of the color signal is amplified by an amplification degree corresponding to the degree of saturation of the color signal by a voltage control amplifying circuit 12. Next, an output of the VCA 12 and the luminance signal subjected to time alignment by a delay element 13 are added by an adder 14, and its frequency characteristic becomes narrow. Also, as for a band pass filter BPF 5, that which has a wide band is used, and in the part in which the degree of saturation is high, a dot disturbance is suppressed, and in the part in which the degree of saturation is low, the luminance signal whose oblique resolution is improved is obtained. In such a way, a satisfactory Y/C separation applied correspondingly to a visual characteristic can be executed.

Title: Semiconductor storage device
Inventor: TSUKAMOTO KAZUHIRO
IPC: G11C11/41
Filed: 1986-12-11
Abstract: PURPOSE:To considerably reduce power consumption by driving an address buffer by means of an address buffer driving means in accordance with the access of an intedended external address. CONSTITUTION:If an external address CAS (column address strobe) subsequent to an external address RAS (row address strobe) falls in the nibble mode of a semiconductor storage device, the CAS comes to a low level L, and a column address (external address ext A1) is inputted, the external address is not inputted and the input level of a NOR gate 3 becomes high in accordance with a rise just after the fall of the CAS. Since the output level of the NOR gate 3 comes to L irrespective of the level of other input signal, the address buffer 2 becomes L until the RAS rises, whereby the address buffer 2 does not operate during that period. Thus, power consumption at the time of operation can be reduced.
