Title: Manufacture of semiconductor device
Inventor: HAMADA KOJI
IPC: H01L21/283
Filed: 1993-03-03
Abstract: PURPOSE:To lower the temperature in formation process of a semiconductor without lowering the quality of a silicon oxide film by thermally oxidizing a polysilicon film after forming the silicon oxide film on the polysilicon film by a method excluding thermal oxide method. CONSTITUTION:A silicon oxide film 2 is formed on a silicon substrate 1, and further an amorphous silicon film 3 is stacked by low-pressure chemical vapor deposition Next, the amorphous silicon film 3 is polycrystallized by heat-treating the silicon substrate, and then a polisilicon film 4 is formed, and after cleaning the surface, a CVD oxide film 5 is grown, and thermal oxidation is performed in atmosphere of H2-O2 at 750 deg.C so as to form a silicon oxide film 6 on the polysilicon film 4. Though it is thermally oxidized at relatively low temperature, the flatness of the interface between the polysilicon film 4 and the silicon oxide film 6 is good, and the unoxidized silicon crystal grains do not exist in the silicon oxide film 6. Accordingly, the temperature in formation process of a semiconductor device can be materialized.

Title: Coefficient transfer discriminator and echo canceller using the same
Inventor: O YOKA
IPC: H04B3/23
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To suppress the possibility of the erroneous transfer of a coefficient by accurately detecting double talk by a first coefficient transfer discriminating means, preventing the erroneous transfer in a section in which a far end signal is not present by a second means, making the residual error of a BG filter smaller than the residual error of an FG filter in a third means, and performing the transfer of a coefficient only when all the first to third judgment conditions are fulfilled. SOLUTION: A first condition judging means 31 obtains correlation between an echo signal z and a first pseudo echo yb by a correlator 10. A square averaging circuit 21 calculates the power of the first pseudo echo yb, and calculates the absolute value of the rate, and discriminates whether or not the rate is within a certain range. A second condition discriminating means 41 discriminates whether or not the power of the first pseudo echo yb obtained by the square averaging circuit 21 is larger than the integral multiple (>=1) of the power of the first error signal eb. Coefficient transfer discriminating means 60 and 70 transfer the coefficient of a BF filter when all the conditions are satisfied.

Title: Optical scanner
Inventor: SUZUKI TAKASHI
IPC: B41J3/00
Filed: 1986-02-27
Abstract: PURPOSE:To correct excellently an irregularity in scanning pitch due to the surface tilt error of a rotary polygon mirror through simple constitution by providing a driving means which allows an optical path returning plane mirror which is arranged between a rotary polygon mirror deflecting device and a plane to be scanned to vary in angle or shift in position so as to correct the surface tilt error of the rotary polygon mirror. CONSTITUTION:A driving source is expanded and contracted by a piezoelectric element 73 as shown by an arrow A according to an applied voltage and the plane mirror 70 is pressed against a fulcrum 74 by a fulcrum pressure spring 72 to rotate around the abutting part. A counterclockwise driving force is obtained by the piezoelectric element 73 and a clockwise driving force is obtained by a return spring 71. The voltage applied to the piezoelectric element 73 is varied in a blanking period wherein a light beam is deflected beyond an area in which information is recorded and the variation of the installation angle of the plane mirror 70 is completed in this period. Consequently, even if the rotary polygon mirror 1-a has a surface tilt error, an optical path return plane mirror surface 70-1 is so controlled as to draw a scanning line at the same position on a photosensitive drum 6, thereby varying the installation angle.

Inventor: PEETAA RAIMAN
IPC: C04B37/00
Filed: 1993-03-03
Abstract: PURPOSE: To produce rings of uniform thickness from an active brazing filler alloy by lifting individual coils of a helix off a metal drum during the short time in which a liquid alloy is cooled rapidly on the metal drum and then coiling them into a helix. CONSTITUTION: Rings of uniform thickness are produced from an active brazing filler alloy by melt-spinning the liquid alloy. The alloy is liquefied in a crucible 3, having a lateral opening whose height is approximately equal to the width of the ring material. The liquid alloy is forced out of the crucible, at a radial distance from the drum center approximately equal to the ring diameter, onto the side surface of a high thermal conductivity metal drum 1 rotating at a high circumferential velocity at a distance from the crucible approximately equal to the ring thickness. The alloy is lifted off, after approximately a quarter to three-quarters turn of the alloy, the metal drum 1 by a mechanical deflector 5 or an injected gas stream.  A ring helix 7 being formed is guided around a winding mandrel 8 which is located on one side of the crucible and has an end flange and a diameter slightly smaller than the inner diameter of the rings, and the rings are cut off from the ring helix 7.

The device makes one turn in a constant direction to represent the peak values P2 and P1 of the sensors 2 and 8 as a time difference t1. The processing part 5 finds the angle theta=1/2Xt1Xw between the sensors 2 and 8 which is viewed from a scanning axis X from the time difference t1 and the angular speed (w) of the shaft 42 of the device 4. Then the position of the body 1 in motion is detected.
