Title: Method for joining carbon member
Inventor: AKIYAMA HIROSHI
IPC: C04B37/00
Filed: 1992-05-12
Abstract: PURPOSE:To obtain a sound composite of a carbon member with other members such as a metal by arranging a member to be joined through Ti or Cr and a metal brazing material on a joining surface of the carbon member and heating the resultant assembly. CONSTITUTION:A joining surface of a carbon member is printed or coated with pasty metallic powder composed of Ti or Cr and a metallic brazing material is then arranged on the metallic powder. A member to be joined is further arranged on the metallic brazing material. The resultant assembly is subsequently heated to a temperature above the melting point of the metallic brazing material in a nonoxidizing atmosphere to carry out the joining of the carbon member. The element (Ti or Cr), reactive with the carbon member and forming a carbide is heated in a state of close contact with the surface of the carbon member by arranging the element forming the carbide separately from the brazing material. Thereby, excessive reaction of the element forming the carbide with the brazing material or the joining member on the opposite side is suppressed. As a result, a reactional layer required for the joining is formed in the interface between the element forming the carbide and the brazing material to afford the objective sound joined body.

Title: Output correcting method for azimuth detector
Inventor: YAMASHITA MITSUHIRO
IPC: G01C21/00
Filed: 1990-05-08
Abstract: PURPOSE:To improve the calculation accuracy of an advance azimuth by deciding a linear advance section from an output of a rotation angle pulse, and correcting automatically a conversion coefficient to a moving distance from the rotation angle pulse of a wheel in its linear advance section. CONSTITUTION:A left wheel speed sensor 1 and a right wheel speed sensor 2 detect the rotation of a gear-like rotor, and a sine wave-like output is obtained in proportion to a rotation of the gear. An output corresponding to the rotation angle of each wheel of every unit time obtained from these sensors 1, 2 is converted to a pulse train by interfaces 3, 4. Subsequently, in accordance with whether a state that a difference of the number of pulses of the left and the right wheels measured at a unit time interval exceeds a prescribed value is continued or not, a linear running state of a moving body is decided. By correcting a wheel constant from the number of pulses detected in a section which is decided to be a linear running state, an advance azimuth of a vehicle is calculated. That is, a wheel constant being a conversion coefficient from a rotation angle pulse to a moving distance is used as a turning angle conversion coefficient for calculating a turning angle of the vehicle by setting the left and the right coefficients as a pair, and its conversion coefficient can be corrected at every roughly prescribed distance running.

Title: Optical amplifier
Inventor: YOSHIDA TAKASHI
IPC: H01S3/10
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To secure a flat gain characteristic about wavelength, even if the temperature changes. SOLUTION: A temperature sensor 4 in the optical amplifier detects the temperature in the periphery of an optical fiber 110, a reference voltage generation circuit 6 controls an AGC circuit 130 on the basis of an output signal of the sensor 4, in such a manner that the higher the temperature around the fiber 110 is, the higher an amplification factor in the fiber 110 is set. For an erbium-doped optical fiber, the higher the temperature is, the smaller the gain in its longer wavelength side will be. Furthermore, the gain characteristic of the fiber 110 is changed also by the strength of exciting light so that the stronger the exciting light is, the larger the gain in its longer wavelength side will be.  Thus when the AGC circuit 130 is controlled, the higher the temperature is, the higher the amplification factor of the fiber 110 will be, the exciting light supplied to the fiber 110 becomes stronger at a higher temperature, which results in a change in the gain characteristic caused by the temperature change is canceled by a change in the gain characteristic caused by changing the intensity of the exciting light, thus the gain characteristic of the fiber 110 becomes flat.
