Patent JP-H04170637-A (JP)
Title: Divider circuit
Inventor: NAKAMURA MASARU
IPC: G06F7/535
Filed: 1990-11-05
Abstract: PURPOSE:To shorten an arithmetic time required for the succeeding dividend by expressing a divisor of n bits as n<n+1>, adjusting the number of digits of the divisor to that of the divident and finding out the succeeding dividend by the constitution of two stages. CONSTITUTION:A divisor Y of n bits is converted into 2<n+1> by a 2<n+1> forming circuit 5 to form a divisor Y', and when a dividend X is more than the divisor Y', the divisor Y' is shifted to the left by an m-(n+1) bit shifting circuit 7 to adjust the number of digits of the divisor Y' to that of the dividend X consisting of m bits. Respective digits are passed through an exclusive OR circuit 11 to find out a difference V between a dividend X1 and the divisor Y'. Then a difference W between the 2<n+1> and a divisor Y2 is found out by allowing digits less than n bits to pass an exclusive OR circuit 8 and an '1' adder 9. The difference W is shifted by an m-(n+1) bit shifting circuit 10 and added to the difference V by a dividend X' forming adder 12 to find out the succeeding dividend X'. Thus, the succeeding dividend can be found out by the two-stage constitution and the arithmetic time can be shortened.

Title: Magneto-optical recording medium
Inventor: KAWAMURA HIROMI
IPC: C23C14/14
Filed: 1986-12-16
Abstract: PURPOSE:To obtain sufficient corrosion resistance with the medium itself by adding two kinds of elements, Cr and Pd, to an amorphous alloy which consists of TbFeCo having magnetic anisotropy in the direction perpendicular to the film plane. CONSTITUTION:Two kinds of the elements, Cr and Pd, are added to the amorphous alloy which consists of the TbFeCo having the magnetic anisotropy in the direction perpendicular to the film plane. A passivation film is liable to be formed on the surface of the amorphous alloy when the Cr is added thereto. This film acts as a protective film and effectively suppresses the local oxidation and selective oxidation in particular. The Pd not only makes contribution to the formation of the passivation film but also has the effect of chemically stabilizing the amorphous alloy; more particularly, the Pd has the preventive power to a salt soln. and effectively suppresses wet corrosion. The stable region of the amorphous alloy is thereby spread to plural oxidation modes by adding two kinds of the elements Cr and Pd and the corrosion resistance is improved overall.

Abstract: PURPOSE:To obtain the org. nonlinear optical waveguide element which can be applied to laser frequency conversion, information control of optical circuits, optical switches, etc., by forming an org. nonlinear optical material layer as a thin layer which can exhibit optical waveguide characteristics into the micropores of inorg. oxide glass. CONSTITUTION:The org. nonlinear optical material-contg. layer is formed as the thin layer. Namely, a mask 2 corresponding, in a negative type, to a desired optical waveguide pattern is provided on the surface of the inorg. oxide glass 1 having the microporous structure. This glass of this state is in succession rested in a liquid contg. nonlinear org. molecules, i.e. the liquid phase state of the molecules or the vapor or mist contg. the molecules as one component, by which the component contg. the org. nonlinear molecules is diffused into the glass according to the optical waveguide pattern. Since the sections diffused with the nonlinear org. molecules are packed with this component into the holes and, therefore, the refractive index is increased as compared to the circumference. The flush type org. nonlinear optical waveguide element formed with this part as the optical waveguide 3 is thus formed. The wide utilization of this element for optical switching, optical modulation, etc., is possible if electrodes 4 are mounted near to the optical waveguide 3 and a voltage 5 is impressed thereto.

Title: Ratio differential relay for protecting transformer
Inventor: TOMITA KAZUO
IPC: H01H83/14
Filed: 1991-11-18
Abstract: PURPOSE:To perform a process to a phase difference without using an auxiliary current transformer by shifting the phase of one of two detection currents to set their phases equal, and performing a ratio differential action to a current signal processed at a phase shifting part. CONSTITUTION:An output (a) from a current transformer 4 on the primary side of a transformer 1, an output of a current transformer 5 on the secondary side of the transformer 1, or a current (c) is directly transmitted to a ratio differential relay 10. As information for each sort of transformer winding is inputted, an instruction value of a necessary phase shifting quantity is transmitted to a phase shift computation unit. The phase shift computation unit performs a phase converting computation by a digital relay, shifts the phase of the current (c), and lets it correspond with the phase of the current (a). The currents (a), (c) of which phases get to correspond with each other are then transmitted to a ratio differential computation unit 18, and information relating to each action circuit is transmitted to a display unit or an output unit. Need of an auxiliary current transformer is thus eliminated, connection at site becomes simple and easy to be securely performed, and a cable capacity can be reduced.

Title: Phase synchronizing oscillation circuit
Inventor: AOYANAGI TAKATOSHI
IPC: H03L7/187
Filed: 1988-11-29
Abstract: PURPOSE:To obtain a prescribed response even if the oscillating frequency of a phase synchronizing oscillation circuit is switched by applying amplifier control to an amplifier circuit in a phase synchronizing oscillation circuit so as to cancel a change in the response of the phase synchronizing oscillation circuit due to a change in a frequency division ratio of a frequency divider circuit. CONSTITUTION:A phase comparator circuit 1 generates an output voltage 7 in response to a phase difference between an input signal 5 and a feedback signal 6 fed back through a 1/N frequency divider circuit 4. Only a low frequency component of the output voltage 7 is extracted by a loop filter 2 and a filter passing signal 11 is amplified by an amplifier circuit 10 to use the result as a control voltage 8 of a voltage controlled oscillation circuit 3. The amplification factor of the amplifier circuit 10 and the frequency division ratio of the 1/N frequency divider circuit 4 are decided by a control signal 12 and the value N is decided depending on the signal 12, then the amplifier circuit 10 applies the amplification of a multiple of AN and the 1/N frequency divider circuit 4 applies frequency division of 1/N. The gain of the amplifier circuit 10 is controlled so as to cancel the effect of the frequency divider circuit 4 due to fluctuation of the value N to keep the response constant even if the oscillated frequency of the phase synchronizing oscillation circuit is changed.
