Title: Radio transmitter capable of compensating for a frequency characteristic of an antenna and/or a coupling circuit
Inventor: MIYAZAKI SHINICHI
IPC: H04B1/036
Filed: 1990-04-26
Granted: 1993-04-06
Abstract: Abstract of the Disclosure:         In a radio transmitter responsive to an input signal for transmitting an output signal through a coupling circuit and an antenna with a radio channel assigned to the output signal, a power level of the ouput signal is kept constant with reference to a frequency characteristic of the antenna and/or the coupling circuit.  The output signal is produced from an amplifier section controlled by a reference voltage which is supplied from a reference voltage generator (27) controlled by a reference voltage controller (23).  The reference voltage controller produces a reference voltage control signal which is based on the frequency characteristic and which is used for adjusting the reference voltage.   In addition,  the reference voltage control signal may be produced with reference to a temperature characteristic of a detector for detecting the output signal.

Title: Serializing system between vector instruction and scalar instruction in data processing system
Inventor: SAKAI KENICHI
IPC: G06F9/38
Filed: 1990-05-10
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE           A data processing system containing a scalar unit,  a vector unit,  and a storage.   The scalar unit receives  scalar  instructions  and vector  instructions, carries out scalar data processing in accordance with the scalar  instructions, and transfers the vector instructions to the vector unit.  The vector unit receives the vector instructions from the scalar unit, carries out vector data processing in accordance with the vector instructions, and contains a post pending signal generating circuit  for generating a post pending signal.  The post pending signal is made active when a post instruction is received from the scalar unit and is made inactive when a right to access the storage is obtained for reading or storing a last element read or stored by the vector instructions preceding the post instruction.  The scalar unit further contains a wait instruction detecting circuit for detecting a transfer of a wait instruction to the vector unit, and an interlock control circuit for suspending executions of instructions which follow a wait instruction which is detected in the wait instruction detecting circuit and each including an operation to access the storage until the post pending signals changes from active to inactive.

Title: Method and apparatus for manufacturing and repairing molten metal containment vessels
Inventor: CONNORS CHARLES W JR
IPC: F27D3/00
Filed: 1992-03-11
Granted: 1997-04-22
Abstract: A method of manufacturing an open top, walled member for containing a molten metal, especially a flowing molten metal or reconstructing a worn or dam-aged member.  The method includes the step of forming the inner walls of a mold which define the inner sur-faces of the walled member of an open metal mesh screen which is meltable by the molten metal which is to be contained.  The next step is to transfer, usually by pumping, an alumina-silicon carbide casting compound into the space between the open mesh metal screen and the outer walls defining the mold, which outer walls may be in situ structures.  If an existing walled member is being repaired, any damaged or worn potions of the existing walled member are removed and the casting compound is poured in to replace these por-tions.  The next step is to apply heat to dry the casting compound while the open mesh screen of the mold remains in place in contact with the casting compound. The final step involves removing the open screen mesh by flowing hot molten metal into the open top, walled containment member.

Title: Fibre optic arrangement for measuring the strength of an electric current
Inventor: PEIER DIRK
IPC: G02B30/25
Filed: 1990-07-12
Granted: 1999-08-24
Abstract: A fiber optics arrangement for measuring the intensity of an electric current utilizing the Faraday effect in which the magnetic field surrounding the conductor through which the current flows affects the polarization condition of the light, the path of which leads through the core of an optical fiber which surrounds the conductor in the form of a coil. The light coupled out of the optical fiber, by means of a beam splitter is divided into two partial light beams; the intensities, after passage through one polarizer being measured by one photodetector, respectively. Expansion of the measuring range of the arrangement is achieved by the fact that the polarizers are rotated symmetrically with respect to one another in comparison to the conventional angle of 45 degrees, the angle between the polarizers and the polarization plane of the light coupled into the optical fiber being between +20 degrees and 40 degrees, or between -20 degrees and -40 degrees.
