IPC: C08G77/06
Filed: 1995-03-16
Abstract: PURPOSE: To prepare an organopolysiloxane by continuously hydrolyzing and condensing an organosilane in a reaction column into which the organosilane and water are fed, and stirred and mixed by means of vibration along the line of stream in the reaction column. CONSTITUTION: In the preparation of an organopolysiloxane where one or more than one kinds of organosilanes as expressed by the general formula Ra SiX4-a (wherein R: H, same or different monovalent hydrocarbon groups, X: hydrolyzable group, (a): an integer of 0-3) and water are continuously fed into the inlet of a tubular reaction column and the organosilane is hydrolyzed to form an organopolysiloxane in the reaction column and the organopolysiloxane is taken out from the outlet of the reaction column, the organosilane and water are stirred by means of vibration along the direction of stream in the reaction column.

Title: Cement composition for mass concrete
Inventor: ISOHATA TATSUO
IPC: C04B7/02
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve the thermal cracking resistance of a mass concrete structure, to reduce self-shrinkage and to enhance thermal cracking preventing effect by specifying the ratio of Al2 O3 to Fe2 O3 in a cement clinker and the 2CaO.SiO2 content of the clinker. SOLUTION: The ratio of Al2 O3 to Fe2 O3 (IM) in the cement clinker is 0.05-0.62 and the 2CaO.SiO2 (C2 S) content of the clinker is 45-75 wt.%. When IM is <=0.62, C3 A having high hydration reactivity, generating a large quantity of heat by hydration and having large self-shrinkage can be made absent and the heat of hydration and self-shrinkage can be reduced. Since strength exhibiting property deteriorates when IM is about 0, the lower limit of IM is 0.05 from the viewpoint of practicality. In the case of <45 wt.% C2 S content, heat generation increases, the insulation temp. of concrete rises and specific strength does not increase. In the case of >75 wt.% C2 S content, the rise of the insulation temp. is suppressed but the exhibition of strength is delayed.

Inventor: MORIYA YOUICHI
IPC: H04L27/227
Filed: 1980-06-19
Abstract: PURPOSE:To achieve accurate synchronous detection by increasing a difference in DC voltage between a synchronous and an asynchronous state by performing phase detection after increasing both output signals of a voltage-controlled oscillator and reverse modulator four times. CONSTITUTION:A quadruplicating device 116 increases a four-phase phase-modulated wave, which is the output of the voltage-controlled oscillator 4 of a phase synchronizing circuit 201, by four times, and a quadruplicating device 117 increases a four-phase phase-modulated wave, the output of a reverse modulating circuit 203, by four times. Then, a phase detector 6 detects the phase difference between the outputs of those quadruplicating devices 116 and 117. The output of this phase detector 6 is supplied to an LPF7, whose output is sent to a voltage comparing circuit  8 to be compared with a reference voltage. consequently, the output of the reverse  modulator 203 has uniform phase distribution between 0-2pi, so the difference between DC voltages obtained in a synchronous and an asynchronous state is increased.

Title: Rolling method of strip
Inventor: KAWANAMI TAKAO
IPC: B21B37/00
Filed: 1982-05-21
Abstract: PURPOSE:To obviate the generation of the phenomenon in which rolling is unstable in the stage of changing a draft during rolling by maintaining the peripheral speed ratio between the peripheral speed of a work roll on a downstream side and the peripheral speed of a roll on an upper stream side smaller than the ratio between the thickness of a strip before rolling and the thickness of the strip after rolling. CONSTITUTION:The peripheral speed of a work roll 1 on an upper stream side is designated as V1, and the peripheral speed of a work roll 2 on a downstream side as V2. If the case of increasing the draft gradually is assumed here, the peripheral speeds of rolls are first set at V1approx.=V2. The peripheral speed of at least one work roll of a pair of the rolls 1 is changed with respect to the peripheral speed of the other work roll. Then, both the neutral point (n) of the roll 2 and the neutral point N of the roll 1 enter a roll bite R and a strip 5 is rolled in a stable state without large fluctuation in the positions of the neutral points (n), R.

Title: Photogenerating elements
Inventor: YUKIMOTO YOSHINORI
IPC: H01L31/06
Filed: 1981-06-01
Abstract: PURPOSE:To minimize the loss due to the restrictions on the structural design by a method wherein the variable multiple junction structure provided with the two kinds of forbidden band width (or optical transition interval) of the first and second layer forming the npn structure is adopted. CONSTITUTION:The photogenerating element is comprised of nipin substrate. The band width of the i type semiconductor layer 3b formed on the p type semiconductor layer 4 is narrower than that of the true semiconductor layer 3. The n<+> semiconductive layer 2b is formed on the layer 3b. Therefore it is needless to add the photocurrent generated in the layer 1 to that generated in the layer 2. Through these procedures, the option and the allowance in the design are increased so that the optimum composition in terms of the physical constant of the layer 1 and 2 may be selected.

Title: Flame sensing device
Inventor: TAKECHI HIROSHI
IPC: F23N5/12
Filed: 1986-04-14
Abstract: PURPOSE:To provide a flame sensing device capable of sensing a flame even under a low voltage by a method wherein a DC voltage is applied between a burner and an electrode so as to sense an electrical current. CONSTITUTION:In case that there is no flame in a burner 21, V+ is the same voltage as Vcc due to a limitless large value of a resistance between the burner 21 and an electrode 21 and is higher than a voltage V- divided by a resistor 24 and a resistor 25. In case that there is a flame in the burner 21, an electrical current is flowed from the electrode 22 to the burner 21, resulting in that a voltage drop is generated at a resistor 23 and the voltage V+ becomes a voltage lower than Vcc by an amount of VFR. If a voltage of V- is set between Vcc and (Vcc-VFR), an output condition of a comparator 26 is reversed between one case in which no flame is present in the burner 21 and the case in which the flame is present so as to enable the flame to be sensed. In case that there is a flame, an electrical current is flowed in the resistor 23 without fail and a voltage drop is generated at both ends of the resistor 23 due to that electrical current and so even if Vcc is low, a stable output can be attained. With the foregoing, the flame can simply be sensed by applying a DC current of low voltage without applying a high voltage between the burner 21 and the electrode 22.

Title: Insulator leak current detecting device
Inventor: MORIMOTO RYOZO
IPC: G01R19/00
Filed: 1989-04-03
Abstract: PURPOSE:To accurately detect the leak current of an insulator by arranging at least two current detectors in parallel, using one to detect the insulator leak current, and using the other for the reference of an external magnetic field. CONSTITUTION:Two current transformers which have substantially the same electromagnetic characteristics are used. One current transformer is mounted in a plane almost perpendicular to a metallic coupler 3 which couples an insulator string device with a steel tower 1 and used as a CT4 for detection which measures the leak current of the insulator string 2. The other one is arranged in parallel to the CT4 for detection and uses as an external magnetic field reference CT5 which measures a fine current induced with the external magnetic field. Signals of currents detected by those two CTs 4 and 5 are sent as light signals to a signal processor to calculate the difference between the both, and consequently the difference is the leak current flowing through the insulators. Consequently, the contamination quantity of the insulators can accurately be detected.
