Title: Manufacture of silicon wafer
Inventor: SADAMITSU SHINSUKE
IPC: H01L21/02
Filed: 1995-03-29
Abstract: PURPOSE: To provide a method for reducing OSF by a low-temperature heat treatment and a method for manufacturing a silicon wafer for solving problems of slippage and contamination even if the aperture of the wafer is increased. CONSTITUTION: OSF 2 occurs generally with a sheet-shaped oxygen deposit 3 as a nucleus, and the critical size of the sheet-shaped oxygen deposit 3 without OSF generation is 0.1μm. However, if the size (length of one side) of the sheet- shaped oxygen deposit has been grown to 0.1μm or longer by a heat treatment at 1,000 deg.C or lower at least for 16 hours before high-temperature oxidation heat treatment in the LSI manufacturing process, a silicon wafer without generation of OSF can be manufactured in the succeeding high-temperature oxidation heat treatment.

Title: Detector
Inventor: MIURA KENZABUROU
IPC: G01P3/488
Filed: 1982-06-09
Abstract: PURPOSE:To obtain a detector which is small in size or thickness and has large outputs with reference to a detector which detects the speed or the extent of movement of an object to be measured with magneto-electric transducers by using the object which is arranged with materials having different magnetic permeability at a predetermined pitch. CONSTITUTION:Magneto-electric transducers 8, 9 are so installed relatively at a certain size that when the transducer 8 is at the position facing a base member 6 or a fitting member 7, the transducer 9 faces the member 7 or the member 6. Therefore, when, for example, the transducer 8 faces the member 6 and the transducer 9 faces the member 7, the magnetic fluxes to be applied from a permanent magnet on the transducers 8, 9 differ respectively on account of a difference in the magnetic permeability that the member 6 and the member 7 possess. As a result, the electric resistance values of the transducers 8, 9 change individually. Outputs are drawn out differentially from the transducers 8, 9 in such a way, whereby the extent of the movement, etc. of an object 5 to be measured are detected.

Title: Radar apparatus airborne
Inventor: UJI CHIAKI
IPC: G01S7/292
Filed: 1989-04-18
Abstract: PURPOSE:To improve a detection capacity aimed to coexist with a clutter by varying a transmission pulse width on the basis of an airplane's own height signal and by obtaining a prescribed S/C ratio at all times. CONSTITUTION:In an exciter, a pulse width and a pulse repetition frequency are varied in proportion to an airplane's own height signal 13. On the occasion, a ratio between an echo and a reception power of a clutter, i.e. S/C, turns to be a prescribed value by varying the pulse width corresponding to a change in the height. On the other side, the alteration of the pulse width necessitates an alteration of a band width of a receiver, and this alteration causes a change in the noise of the receiver and further deterioration in an S/N ratio and lowering of reception sensitivity. In order to prevent this lowering, the pulse repetition frequency is varied to change a pulse integration frequency in a signal processing system, and thereby the S/N ratio can be improved by an integration effect.

Title: Line concentration-distribution system using photo-branching filter
Inventor: ISHIO HIDEKI
IPC: H04Q3/60
Filed: 1978-08-15
Abstract: PURPOSE:To attain duplex communication only by providing one optical fiber line to each subscriber by applying wavelength-division multiplex transmission technology. CONSTITUTION:Signals of wavelengths lambdaD1-lambdaD3 from exchange station 1 are tranmitted through optical fiber 30 to line concentrator 7, where they are separated by an interference-film filter, etc., and separated signals are separately transmitted through optical fiber lines 31-33 corresponding to subscribers 21-23 and then inputted to photo receiver 5 by way of corresponding photo separating couplers 6. Signals of wavelengths lambdaU1-lambdaU3 from subscriber sides, on the other hand, reach line concentrator 7 via optical fiber lines 31-33 by way of the route opposite to signals from exchange station 1 and all signals are transmitted from line concentrator 7 to exchange station 1 via one optical fiber 30. In this way, only providing one optical fiber to each subsciber makes duplex communication possible and required optical fiber lines can be reduced most in number.

Title: Method of controlling density of carrier in epitaxial film of chemical semiconductor
Inventor: MAEDA KATSUNOBU
IPC: H01L31/00
Filed: 1978-08-14
Abstract: PURPOSE: To control the density of carrier in epi-film of GaAs or GaAs 1-x P x  by introducing NH 3  into vapour phase growth reaction system at a controlled rate.  
     CONSTITUTION: In vapour phase growth of epi-film of GaAs or GaAs 1-x P x , it is possible to make inert the impurities which determine the conduction type, by introducing gaseous nitrogen compound. It is, therefore, possible to control the density of cattier in the growth film. The nitrogen compound, NH 3  and CH 4 NH 2  can effectively be used because of easiness of control of the introduction rate at room temperature. In case of NH 3 , it is effective to maintain the density in reaction gas below 6%. According to this method, it is possible to obtain the epi-film of a desired low carrier density by introducing NH 3  while maintaining constant amount of introduction of P or n type impurities. In addition, the variation of carrier density in the thicknesswise deirection can be reduced. Further, it is possible to obtain a drastic or sharp change of carrier density at the boundary between two regions of different carrier densities.
