Title: Xenopus laevis bone morphogenic protein, dna encoding same and use thereof
Inventor: MURAKAMI KAZUO
IPC: A61P19/10
Filed: 1990-09-05
Abstract: Disclosed are (1) a Xenopus laevis bone morphogenetic protein (BMP), (2) a DNA comprising a DNA segment coding for a Xenopus laevis BMP, (3) a.transformant bearing a DNA comprising a DNA segment coding for a Xenopus laevis BMP and (4) a method for preparing the Xenopus laevis BMP which comprises culturing the described in (3), producing and accumulating the protein in a culture, and collecting the protein thus obtained. Cells transinfected or transformed with the DNA allow large amounts of the Xenopus laevis BMP mature peptides to be produced, which causes the advantageous production of the peptides, which promote the synthesis of proteoglycan and can also be utilized for analysis of the mechanism of organism, particularly human bone-cartilage morphogenetic reaction, and as therapeutic agents for osteoporosis.

Title: Method and apparatus for producing human autologous collagen
Inventor: ZOCCHI MICHELE
IPC: A61L27/24
Filed: 1990-09-20
Abstract: ABSTRACT OF THE DISCLOSURE             This invention provides a method and the apparatus for producing human autologous collagen from the human fat tissues and specifically for a method of disintegrating fat cells using ultrasonic energy and separating fats, blood, water and serum from the collagen, all of which can be accomplished without removing material from the harvesting syringe. The purpose of the invention is  to produce autologous collagen which is useful in several cosmetic procedures used to treat all the problems caused by ageing.          In accordance with the procedure taught in the invention after fat cells have been removed from the subject in a harvesting syringe, first the material in the syringe is subjected to an ultrasonic energy source  of a range between 20 kHz and 3 mHz which destroys the fat cells by rupturing them which allows the oil in the fat cells to be separated from the residual cell] walls, after which the harvesting syringe is placed in a  specially designed centrifuge allowing for the blood, serum, fat cell ail and collagen to be completely separated. In the fat cell disintegration on step, when applying ultrasonic energy, two alternative devices may be employed with the harvesting syringe containing the material. In one, the syringes are placed in a container filled with cold liquid and subjected to ultrasonic energy. The second, preferred method utilizes a high intensity ultrasonic processor that includes a probe that can be placed in the harvesting syringe that is mounted individually in a metal support filled with a cold liquid. In the separation stage, a multi-bodied centrifuge is provided which holds up to four harvesting syringes safely while subjected to centrifugal action to permit the separation of the material as described herein. With the use of the present invention human autologous collagen can be produced in minutes without removal from the frozen storage in an individual patient collagen bank.

Title: Light-receiving element
Inventor: SHIGA NOBUO
IPC: H01L27/144
Filed: 1990-10-03
Abstract: ABSTRACT OF THE DISCLOSURE   Most optical communication systems have a function of detecting the presence/absence of a light input.  In such an optical communication system, an output optical current generated by a light-receiving element is also consumed by the monitor function.  For this reason, when a light input is very weak, a disturbance occurs in an output is very weak, a disturbance occurs in an output electrical signal for information transmission. This invention has its object to provide a light-receiving element which can monitor a light signal input without causing a disturbance in an output electrical signal.          For this purpose, according to this invention, a light-receiving element has the first active area irradiated with a light signal, and the second light-receiving element irradiated with a leakage light component of the light signal.  An output optical current for information transmission is generated by the light signal radiated on the first active area, and a monitor light output current is generated by the leakage light component of the light signal radiated on the second active area.          Therefore, even if an incident light signal is very weak, a monitor output optical signal can be independently generated.  For this reason, no disturbance occurs in an output electrical signal for information transmission.

Abstract: ABSTRACT OF THE DISCLOSURE A burner which feature an internal premixing zone is used for operating an internal combustion engine, a combustion chamber of a gas turbine group or firing equipment.  The burner itself consists of at least two hollow partial conical bodies (1, 2) located one upon the other in the flow direction and with their longitu-dinal axes of symmetry (1b, 2b) offset radially rela-tive to one another.  These create tangential air inlet slots (19, 20) with opposite flow directions for a com-bustion air flow (15) into the internal space of the burner, which has the shape of a hollow conical space (14).   A nozzle (3) by means of which a gaseous fuel (12) is prepared acts within the hollow conical space (14).  In the region of the nozzle (3), the tangential air inlet slots (19, 20) are closed by plugs (24, 25) which produce a high blow-out limit irrespective of the mass flow of the burner.
