Title: Remover of iron and/or manganese in water and its manufacture
Inventor: HAGIWARA ZENJI
IPC: C02F1/64
Filed: 1978-09-20
Abstract: PURPOSE: To obtain an inorganic remover of iron and manganese dissolved in water by the procedure in which zeolite as a carrier is treated with a solution of a divalent manganese salt and a permanganate and then baked in a specific temperature range.  
     CONSTITUTION: Zeolite as a carrier is dipped in a solution containing a divalent manganes salt, e.g., manganese chloride, etc., and a permanganate, e.g., potassium permanganate, etc., to impregnate these salts into the zeolite phase, and then the carrier so treated is baked at 400°C or more and in a temperature range in which no structural fracture of the zeolite takes place to obtain an inorganic remover. The use of the remover in the treatment of ground water, industrial water, etc., results in the concurrent and efficient removal of a small amount of iron and/or manganese present in water.

Title: Ion source of ion beam application apparatus
Inventor: USAMI YASUTSUGU
IPC: H01J27/16
Filed: 1992-05-08
Abstract: PURPOSE:To stably take out a large amount of ion beam of multi-valent ion, molecular ion and so on by increasing the degree of vacuum in a vacuum case simultaneously with increasing of gas pressure in an ionization chamber in accordance with a conductance control at an emitting outlet of the ionization chamber so as to reduce the amount of gas leaking from the case. CONSTITUTION:Sample gas is led into an ionization chamber 2 while a flow rate is adjusted by means of, for example, a variable leak valve 5, and at the same time a microwave 2 from a magnetron 1 is led therein so that an electromagnetic field produced by a solenoid coil 4 is applied thereto. Thus, a plasma 6 is produced by the mutual action between the magnetic field and the electric field by the microwave. The plasma 6 is absorbed by an electrode 7 to be emitted from a emitting outlet 8 into a vacuum case 11 so that the plasma 6 may be radiated onto a wafer 10 as an ion beam 9. At this time, the emitting outlet 8 is appropriately throttled to control the conductance of the fluid, the degree of vacuum in the case 11 is increased simultaneously with increasing of gas pressure in the chamber 3, thereby gas leaking from the case 11 is reduced. Namely, the gas pressure in the ionization chamber 3 is increased and the amount of increased gas pressure in the case 11 is made smaller.

Title: Leakage detection method of liquid transferring pipeline
Inventor: KOSUGI SANAI
IPC: F17D5/02
Filed: 1982-07-02
Abstract: PURPOSE:To detect even a small amount of leakage by estimating the pressure at a certain point from pressures at measurement points upstream and downstream it and detecting a leakage from the estimated value and the actual measured value. CONSTITUTION:The liquid pressure is measured for a small sampling time or continuously at measurement points of a fluid transferring pipeline 1 and sent from pressure transmitters 4 to a computer 9. The pressure at a certain measurement point P0 at time (t) when no leakage is present is calculated from the measured value at a measurement point P1 upstream and apart from the point P0 by DELTAx1 at t-DELTAx1/a and the measured value at a measurement point P2 downstream and apart from the point P0 by DELTAx2 at t-DELTAx2/a to determine the estimated value, where (a) is the speed of sound in the pipeline 1. A leakage can be detected by comparing the estimated value with the actual measured value at the point P0 at time (t).

Title: Fuel supply system for autombile
Inventor: CHIYAARUZU ETSUCHI TATSUKII
IPC: F02M37/04
Filed: 1995-05-15
Abstract: PURPOSE: To realize a fuel supply system that has two-stage pump, and has high performance in a dry state and in a high temperature state of fuel. CONSTITUTION: The main fuel tank in an automobile montains a reservoir 40 in which is located a two-stage electrically operated pump. The first stage 152 is a transversely rotating channel pump which draws fuel from the main tank and delivers it to the reservoir 40. The second stage 146 is a rotary turbine pump which draws fuel from the reservoir 40 and delivers it to the vehicle engine. The reservoir 40 has overflow restriction means 124, 126 which allow air to vent while the reservoir 40 is filling but which restricts fuel flow when the reservoir is full. This creates pressure in the reservoir to create back pressure against the first stage pump, shut down fuel flow from it, and also increase pressure of the fuel inlet of the second stage thus increasing the efficiency of the second stage pump.

Filed: 1989-05-09
Abstract: PURPOSE:To completely separate a luminance signal from a chrominance signal and to reproduce the oblique high-pass component of the luminance signal by transmitting a color difference signal component on a second channel after applying time division multiplexing. CONSTITUTION:A side panel component is transmitted on the second channel in the 1/3 of the first half of a horizontal scanning period, and two color difference signals (I signal and Q signal) are time-division multiplexed and transmitted in the remaining 2/3 period. At a demodulation circuit, the I signal and the Q signal are modulated with chrominance subcarrier signals with different 90 deg. phases by multipliers 209a and 209b, and are added with an adder 210a, then, it becomes one modulated signal. A complete luminance signal can be obtained by subtracting it from a composite video signal by an adder 210b, and both the I signal and the Q signal are supplied to a matrix circuit 212, then, they are converted to R, G, and B primary color signals. In such a way, complete Y/C separation can be performed at a receiver side, therefore, no transmission in which the oblique high-pass component of the luminance signal is eliminated at a transmission side is required, and the oblique high-pass component of the luminance signal can be reproduced.

Abstract: PURPOSE:To provide a method capable of standardizing a failure point at a narrower interval than an installation interval by installing current sensors at an overhead earth-wire, and sending a current and a phase at the time of an accident to a central device so as to standardize an accident point by the central device. CONSTITUTION:Two sensors are installed at each of several steel towers, and an interval between the steel towers with the sensors installed is divided into sub-blocks by two kinds of methods. In any sub-block, the probability of an accident in the sub-block is made the value of an output layer, and the current value, phase difference and current difference of four current sensors are inputted to an input layer. The current and phase data at the time of an accident are simulated and learned to complete a neural network in advance. At the time of an accident, failure points in both neutral networks are obtained and combined to standardize the failure point. The failure point can be thereby standardized in a block smaller than the installation interval of the sensors.
