Title: Selection of lc eluting conditions and minicolumn
Inventor: ISHIDA YASUO
IPC: G01N30/86
Filed: 1987-03-24
Abstract: PURPOSE:To select eluting conditions of a liquid chromatography accurately, by cutting a plastic minicolumn having a sample developed by a development solvent as object along the axis thereof to irradiate the cut plane of a packing agent with light. CONSTITUTION:A plastic minicolumn 1 has a transparent plastic column 2 about 10cm along with the inner diameter of bout 1mm filled with a packing agent 4 which is used in a column of a liquid phase chromatography intended to select eluting conditions. Two grooves 6 and 8 for cutting are provided on the external wall surface of the column 2 at positions of 180 deg. therebetween along the axis thereof. When one end of the minicolumn 1 with a sample on is immersed into a development solvent 10, the solvent 10 rises through the minicolumn 1 owing to capillarity to develop components of the sample. After a fixed time, the minicolumn 1 is taken off and mounted on a holder 12 for chromatoscanning of thin layer chromatography to be cut along the grooves 6 and 8. The cut plane of the column is irradiated with light and a quantitative measurement of concentration of the components and separation state of the cut plane is performed thereby setting eluting conditions.

Abstract: PURPOSE:To prevent a malfunction and to extend communication distance by transmitting and receiving a burst wave by spread spectrum communication by a signal generation part, a spread spectrum modulation part and a spread spectrum demodulation part. CONSTITUTION:A burst signal (c) generated in the signal generation part of a deciding device 10 is modulated in a spread spectrum modulator 15 and the burst signal is transmitted from an antenna 16. The antenna 21 of a response device 20 receives the signal and generates a reception signal. At this time, when a door to be an object to be monitored is closed, a switch 22 transmits the reception signal to a solid resonance element 23, the resonance element 23 resonates by the reception signal and the antenna 21 transmits it as an echo wave. Where the antenna 16 of the device 10 receives the echo wave, the reception signal is transmitted to a spread spectrum demodulator 17 and it is demodulated. A decision part decides the state as the opening and closing state of the switch 22 of the device 20 based on the demodulation signal from the demodulation part. Thus, by transmitting and receiving the burst wave by spread spectrum communication, a malfunction can be prevented and communication distance can be extended.

Abstract: PURPOSE:To provide a cement material which can be sintered at a low temperature and hardly pollutes a sensor material by adding an Li element of a specific % by the ratio of Li/SrTiO3 to SrTiO3 in a sensor cement using SrTiO3. CONSTITUTION:In a sensor cement using SrTiO3, an Li element of 1 to 15 atom% by the ratio of Li/SrTiO3 is added to SrTiO3. The SrTiO3 cement to which the Li element is added is sintered about 1000 deg.C, and generation of white glass-state phase is found in an electron microscope observation of the cement sintered about 1100 deg.C, and the SrTiO3 cement to which the Li element is added can be used as a cement to be sintered at a low temperature. Then, in a BaSnO3 exhaust gas sensor and the SrTiO3 cement sensor, influence of use of the Li/ SrTiO3 cement on BaSnO3 can not be found, and the SrTiO3 cement with Li added is the cement with little influence on a sensor material. Thus, a cement material which can be sintered at the low temperature and hardly pollutes the sensor material can be obtained.

Abstract: PURPOSE:To shorten a distance between a main burner and outlet of a furnace, and to realize a low NOx combustion without increasing the amount of unburnt gas, by a method wherein a pulverized coals heated in using the gas exhausted from the furnace are led into a cyclone and are separated into fixed carbon particles and volatile matter, and both of them are separately thrown into the furnace. CONSTITUTION:After pulverized coals are heated by exhaust gas which passes the inside of a heat exchanger 12 together with primary air for conveying them, they are led into a cyclone 13, and are centrifugally separated into fixed carbon particles, ash and volatile matter. The volatile matter is sent into an additional air port 17 for a furnace 1 and is fed into the furnace 1, and the fixed carbon particles are sent into a main burner 4 and are thrown into the furnace 1 together with secondary air and burned. Since a space between the main burner 4 and the additional air port 17 becomes in the state of a reducing atmosphere, NOx produced within the zone of the main burner is reduced by this reducing atmosphere and a proper temperature of exhaust gas, and the amount thereof is decreased. Furthermore, since the combustion speed of the volatile matter is higher, a distance between the additional air port or the top of the main burner and the outlet of the furnace can be shortened.
