Title: Method for concentrating granulocyte-macrophage colony stimulating factor
Inventor: NAKAZAWA HIROSHI
IPC: C07K14/535
Filed: 1987-10-09
Abstract: PURPOSE:To industrially and advantageously obtain the titled substance useful for phylaxis, etc., by reducing and solubilizing a granulocyte.macrophage colony stimulating factor derived from a recombinant Escherichia coli, oxidizing the solubilized factor, removing impurities by ion exchange high-speed liquid chromatography and concentrating the resultant substance. CONSTITUTION:An inert type granulocyte.macrophage colony stimulating factor derived from a recombinant Escherichia coli is treated with a reducing agent, such as dithiothreitol, to cleave intramolecular and intermolecular disulfide bonds. The obtained solubilized factor is then primarily purified by gel filtration chromatography, etc. An oxidizing agent, such as glutathione, a nonionic surfactant, such as polyoxyethylene dodecyl ether. And a chelating agent, such as ethylenediaminetetraactic acid, are added to oxidize and activate the resultant reduction product. The nonionic surfactant, oxidizing agent, reducing agent and chelating agent which are impurities are then removed by using ion exchange high-speed liquid chromatography and simultaneously concentrated to afford the aimed granulocyte.macrophage colony stimulating factor.

Title: Method for separation by adsorption and adsorbing device
Inventor: REON AI
IPC: B01D53/04
Filed: 1991-10-03
Abstract: PURPOSE: To provide an adsorber and a method for separation with high performance (yield/energy) and with a short treatment cycle by adsorption of a component from a gaseous mixture. CONSTITUTION: An adsorber having a long and upright shape includes two perforated panels 6 and 7 between which an adsorbent is packed.

Title: Inverter circuit
Inventor: HIRAMATSU AKINORI
IPC: H05B41/24
Filed: 1990-09-25
Abstract: PURPOSE:To prevent both elements from being put on simultaneously by stopping a timer under conditions where there is no possibility of generation of ON signal in one of the element when the other element is fed back from a load while the one element is driven by the timer. CONSTITUTION:To a direct current power source E1 a load circuit including an inductor L1 and a load (l) is connected through switching elements Q1 and a condensor C0. An oscillation current flowing in this circuit Z is fed back with a feedback coil n2 to only a control end of element Q1, and only the element Q1 is ON-OFF controlled at a specified cycle determined by the oscillation current. A control means X detects the OFF time of the element Q1 by a detection circuit 1, and at the OFF time a timer circuit 3 is triggered by a trigger circuit 2 to operate a timer and by the output of circuit 3 the element Q2 is put on for a fixed time. The means X stops operation of the circuit 3 under conditions where the element Q2 is not allowed to generate an ON signal when it stops operation of circuit 3 forcibly with an inverter stop signal circuit 4. In this way simultaneous on operation of the elements Q1, Q2 is prevented.

Title: Airplane guiding device
Inventor: OKADA SATOSHI
IPC: G08G5/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To guide an airplane without generating congestion even when traffic amounts are increased not by turning on a light when a preceding airplane passes within a constant distance, but by turning on the light just after the preceding airplane passes beyond the constant distance. SOLUTION: A light turning-on state controlling part 5 inquires the existing state of an airplane to an airplane existing state monitoring part 12, and confirms the present position. A control signal is transmitted to a light and sensor control signal transmitting part 6 so that a light within a constant distance ahead of the airplane can be turned on according to this. The light and sensor control signal transmitting part 6 transmits the control signal through a rubber transformer TR0 to a light turning-on circuit. Each light and sensor controlling part C1 -Cn detects that the turning-on information is belonging to a corresponding light, and turns on the light. In this case, when the preceding airplane passes within the constant distance, the light is not turned on, and just after the preceding airplane passes beyond the constant distance, the light is turned on.

Title: Display device
Inventor: SUZUKI MASAYUKI
IPC: G02F1/17
Filed: 1984-12-06
Abstract: PURPOSE:To change the wave front state of an incident luminous flux and to modulate light by moving the granular material existing in liquid. CONSTITUTION:Heaters 14 are energized to generate heat with the picture elements desired to be displayed and the heaters 14' are energized to generate heat with the picture elements desired not to be displayed. Then bubbles 12 move respectively to the heaters which generate heat and the bubbles are disposed only to the picture elements desired to be displayed when viewed from the outside. The other bubbles are concealed by light shieldable belt-like solids 11' and are invisible. If the liquid 13 is the liguid having no light transmissivity, the light from a plane light source 16 passes only through the bubble parts and therefore only the bubbles emit light and visible. Even if the liquid 13 is the liquid having light transmissivity, the light is scattered as a result of the refraction and reflection of the light by the bubbles and therefore the bubble parts can be identified from the other parts. The intended display is thus made possible.
