Filed: 1990-03-22
Granted: 2011-04-12
Abstract: A novel growth factor specific for vascular endothelial cells has been identified in conditioned medium of bovine pituitarly derived folliculo stellate cells. This factor, named folliculo stellate derived growth factor (FSdGF) or vascular endothelial growth factor (VEGF), was purified to homogeneity by a combination of exclusion chromatography. Mono S ion exchange chromatography and hydrophobic chromatography on a C4 reverse phase HPLC column. The factor is also found in the murine AtT-20 cell line. FSdGF, having a molecular weight of about 43,000 daltons, was characterized as a glycoprotein composed of two homologous subunits with a molecular weight of about 23,000 daltons.

Title: Apparatus and method for linearizing the operation of an external optical modulator
Inventor: TRISNO YUDHI
IPC: G02F1/35
Filed: 1991-09-12
Granted: 2000-08-15
Abstract: ABSTRACT OF THE DISCLOSURE     A modulating signal is predistorted to linearize the output of an optical intensity modulator.  The modulating signal is split into first and second paths.  In the first path, the signal is phase shifted.  In the second path, distortion components are introduced.  The phase shifted signal from the first path is then combined with the distorted signal from the second path to provide a predistorted signal for use in modulating a light source.  The distortion generator can comprise a diode pair coupled with opposite polarities in parallel.  Both diodes are forward biased, and the pair is coupled in series with the input signal to provide the desired predistortion.

Title: Microwave oven having a function for matching impedance
Inventor: MINAKAWA HIROSHI
IPC: H05B6/68
Filed: 1993-01-20
Granted: 1997-02-25
Abstract: A microwave oven includes a heating chamber, a turntable provided in the oven, a magnetron, a waveguide for guiding the microwave generated by the magnetron into the heating chamber, an electric field sensor provided at the inner wall face of the waveguide or the heating chamber, a metal reflector provided rotatably inside the waveguide for adjusting the impedance of a load at the heating chamber side by its rotation angle, and a circuit responsive to an output of the electric field sensor for controlling the rotation angle of the metal reflector.          The control circuit includes a first program for controlling the rotation angle of the metal reflector according to a first method within a predetermined time period from the start of operation of the microwave oven, and a second program for controlling the rotation angle of the metal reflector according to a second method different from the first method after elapse of the predetermined time period.  For example, in the first method, the rotation angle of the metal reflector is sequentially controlled so that the output of the electric field sensor is minimum, and in the second method, the rotation angle of the metal reflector is fixed to an average value of the rotation angle of the metal reflector of the first method.          The initial rotation angle of the metal reflector is determined so that impedance matching can be obtained when load of approximately 300-500cc calculated in water load is placed at the center of the heating chamber.

Abstract: A pair of truss brackets are secured to the roof of an underground passage adjacent to opposing ribs of the passage.          The truss brackets each include a roof engaging surface and a truss supporting arm member extending from the roof engaging surface.  A pair of U-bolts are supported by the arm members of the truss brackets.  Each arm member extends horizontally from the truss bracket to an enlarged end portion of the arm member.          The U-bolt  is horizontally movable  in a vertically hanging position on the arm member and is restrained by the enlarged end portion from disengagement from the arm member. The U-bolts are pivoted on the truss brackets to a horizontal position for connection to truss members which are connected to each other and tensioned to apply an uplifting force to the roof.  As the truss members are connected and tensioned, the U-bolts are retained for a range of horizontal movement on the arm members to facilitate adjustments in the position of the U-bolts on the truss brackets.
