Abstract:
A system for detecting leakage of gas, capable of easily and reliably detecting the leakage of gas in a field of a predetermined range. The system for detecting leakage of gas comprises a gas feeding amount detector means (1) for detecting the feeding amount of gas at the main gas pipe which branches into individual user pipes, a gas using rate detector means (2) for detecting the using amount of gas at individual users, and a leakage determining means (3) which finds the total amount of the used gas as the sum of amounts of gas used at individual users, and compares the total amount of the used gas with the gas feeding amount to determine if there is a leakage of gas between the main gas pipe and individual users.

Abstract:
An ion generating element (10) has at least one first discharge portion (12) for generating positive ions and at least one second discharge portion (13) for generating negative ions. The first and second discharge portion (12, 13) are mounted or printed on one dielectric body (11). The first discharge portion (12) has a pair of a first discharge electrode (12a) and a first induction electrode (12b). The second discharge portion (13) has a pair of a second discharge electrode (13a) and a second induction electrode (13b). The first and second discharge electrodes (12a, 13a) are provided on the surface of the dielectric body, and the first and second induction electrodes (12b, 13b) are buried in the dielectric body (11). The first and second discharge portions (12, 13) are spaced from each other independently on the same plane of the dielectric body (11). With this structure, neutralization of generated ions is suppressed and positive and negative ions can be emitted effectively, thereby further improving the ion generation efficiency.

Abstract:
The signals modulated by a carrier having certain frequency are subject to intensity modulation in a multi mode resonant type laser diode (16) to generate optical modulation signals. The optical modulation signals are sent to a light receiving module (13) through a multi mode optical fiber (23) as an optical transmission line (12). A light receiving device (23) in the light receiving module (13) photoelectrically converts the optical modulation signals into the carrier modulation signals. The optical fiber (23) is a graded index type plastic optical fiber in which in which the refractive index in the core part gradually changes as the function of the distance from the center to the power of 2.4 to 2.9.

Abstract:
A method for producing fine particles, including: discharging a fine particle material liquid, where solid materials to be formed into fine particles are dissolved or dispersed in a solvent or are melted, from two or more discharge holes in a downward vertical direction, to thereby form liquid droplets; and solidifying the liquid droplets discharged to form fine particles, wherein in the discharging a fine particle material liquid, gas flow is supplied at angle of greater than 0° but 90° or smaller to the downward vertical direction, and wherein an initial discharge velocity of the liquid droplets discharged from the discharge hole located at an upstream side of the gas flow in a flowing direction thereof is equal to or higher than an initial discharge velocity of the liquid droplets discharged from the discharge hole located at a downstream side of the gas flow in the flowing direction thereof.
Abstract:
A semiconductor device has a plurality of memory cells storing two bits of data in a cell, and a first reference cell (RCl) and a second reference cell (RC2) being shared by the plurality of memory cells. When programming the memory cell, programming a program subjected cell and refreshing a refresh subjected cell are both verified with a threshold value of the second reference cell corresponding to a programmed state of the memory cell. The second reference cell is programmed with a first threshold value (PRGV) to verify when programming, and is refreshed with a second threshold value (REFV) lower than the first threshold value to verify when refreshing.
