Title: Electrostimulation chamber for cell
Inventor: SOGAWA KOJI
IPC: C12N15/09
Filed: 1988-07-28
Abstract: PURPOSE:To obtain an electrostimulation chamber for cell having decreased heat- generation in the application of electric field and applicable even to a cell suspension having high salt concentration by placing a pair of electrodes having a prescribed height to the bottom-side of the opposite inner walls of a container for holding a cell suspension. CONSTITUTION:A pair of electrode plates 12, 14 are oppositely positioned on the bottom plate 10 of the subject chamber. The thickness of the electrode plate is <=1mm and larger than the size of the cell to be fused or subjected to gene-introduction treatment. The inner wall faces 16, 18 on the electrodes 12, 14 are made of an electrically insulating material. The cell-fusion can be performed in the chamber by the following procedures. A suspension 2 containing the cell to be fused is poured into the chamber and left standing for several minutes to cause spontaneous precipitation of the cells 8 on the bottom plate 10. An AC electric field is applied to the electrode plates 12, 14 to effect the contact of the cells 8 with each other and form a pearl chain. Thereafter, a high-voltage pulse electric field is applied between the electrode plates 12, 14 to perform the cell-fusion. Since the electric field is applied only between the electrode plates 12, 14, the heat-generation is decreased to improve the yield of cell-fusion and gene-introduction.

Title: Device to detect abnormality in gas supply facilities
Inventor: HORIIKE YOSHIO
IPC: F23N5/24
Filed: 1990-07-18
Abstract: PURPOSE:To omit safety check by man by detecting automatically a variation in the gas pressure in gas supply facilities on the side downstream of a pressure regulator and distinguishing normal gas pressure variation or abnormal gas pressure variation or abnormal gas pressure variation from the relation between the variation pattern and time. CONSTITUTION:When the output of a pressure sensor 8 is, for instance, over 330 mm H2O, a timer means 9 starts operation and makes the output of the timer means 9 HIGH. And then the output of the timer means 9 is made LOW after, for instance, 24 hours. A judgement means 10 monitors the signal from the timer means 9 and the signal from the pressure sensor 8. If the signal from the pressure sensor 8 is over 330 mm H2O continuously for 24 hours, the judge ment means judges that there is a pressure abnormality and outputs signal to an output means 11. The monitoring time is set so as to be able to eliminate the effect of a pressure rise due to temperature.

Title: Gas sensor
Inventor: ITOU KENTAROU
IPC: G01N21/78
Filed: 1983-10-13
Abstract: PURPOSE:To obtain a stable, highly reliable gas sensor without effects of temperature and time change, by detecting the transmitted light through an element, wherein a specified metal and a solid compound are laminated, detecting the transmitted light through an element, wherein the solid compound and an ordinary metal are laminated, performing the comparison, and detecting a gas. CONSTITUTION:First and second element 2 and 3 are arranged in close proximity in a cabinet, in which outer air can flow. The first element comprises the laminated layer of the following materials: a metal (pd) 6, which adsorbs a gas when the metal is contacted with a hydrogen compound gas and yields a hydrogen atoms by dissociation; and a solid compound (WO3) 7, whose light absorbance is changed due to the reduction of the hydrogen atoms. The element 3 is formed by evaporating a metal 9 such as Cu, Al or the like, which does not adsorb and dissociate the hydrogen compound gas, on the same solid compound 8. Light from a light source 5 is transmitted through the elements 2 and 3 and inputted to light receiving elements 10 and 11. The detected signals E1 and E2 are compared (E2-E1)/E2=Es by a comparing and detecting circuit 12. Thus the gas is detected without the effects of the temperature and time change.
