Abstract: An organic germanium compound to be effectively used for curing AIDS or making AIDS asymtomatic in various forms is expressed by the following rational formula: ##STR1## wherein n is an integer of 1 or 2 or more, is in the form of a white acicular or needle crystal, shows a solubility of 1.570/100 ml in water at 25.degree. C. and exhibits a melting (decomposition) point of 240.degree. C.

Abstract: A converged ion beam apparatus wherein a very small beam spot can be formed with a high energy ion beam after passing a reduced route in which a type of the ion beam is classified. The device is incorporated in an apparatus wherein an ion beam from an accelerator is introduced in a spot to a specimen by way of an ion type classifying device, an objective collimator and a beam collector to perform reforming of a surface or an analysis of physical properties and/or composition or the like of a small area of the specimen. The objective collimator is disposed just on the downstream of the accelerator, and an analyzing component for analyzing an ion type and energy of a beam is interposed in a drift space in an object distance between the objective collimator and a quadruple pole magnetic lens. Several components of the apparatus are also improved including the quadruple pole magnetic lens, an objective slit device and a specimen chamber.

Abstract: This invention discloses a fibrinophilic urokinase complex which is a complex of urokinase with a urokinase inhibitor or tissue activator inhibitor and has a molecular weight of 97,500.+-.3,000 and a method for the production of this fibrinophilic urokinase complex from urine. The urokinase complex can be used, as a thombolytic agent exhibiting an outstanding ability to dissolve thrombus.

Abstract: An apparatus for uniformly distributing a liquid having dual gaseous and liquid phases for use with a heat exchanger is disclosed. A liquid spreading device of the apparatus includes a main pipe extending along the full length of a header of the apparatus, and a plurality of branch pipes connected to the main pipe and extending perpendicularly to the main pipe just above and along the full width of descending flow entrances of a core of the heat exchanger. Each branch pipe has a plurality of liquid spreading holes perforated in a predetermined spaced relationship at the bottom thereof. Thus, liquid can be distributed from the apparatus substantially uniformly within a deviation of, for example, .+-.10 percent.
