Title: Excavation cutting edge and manufacture thereof
Inventor: YAMAGISHI YOSHINORI
IPC: E02F9/28
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a bucket tooth wherein the penetration resistance of a cutting edge to an object of excavation does not change greatly by making the cutting edge wear totally in a sharp state without getting dulled even if it wears during use. SOLUTION: A bucket tooth 11 is formed into a double structure made up of a tooth skin portion 12 on the surface side and a core portion 13 inside by forging. The tooth's inner core portion 13 uses a material that becomes harder after thermally treated by burning than the skin portion 12. If the skin portion 12 wears during use, the inner core portion 13 that is harder than the skin portion 12 exposes itself and wears retaining sharpness without getting dulled. Therefore, the penetration resistance of the cutting edge of the tooth to an object of excavation does not change greatly from when put to use, thereby retaining its bite into an object of excavation in good condition.

Title: Optical amplifier
Inventor: SHIGEMATSU MASAYUKI
IPC: H01S3/094
Filed: 1991-11-15
Abstract: PURPOSE:To reduce the variation in light amplification gain, and to lessen the distortion of waveform of a signal light by providing an attenuation means with which the signal light amplified by the main body of a light amplifier is outputted by attenuating it with almost complementary wavelength characteristics against the wavelength characteristics of the light amplification gain of the light amplifier main body. CONSTITUTION:The signal light made incident on one end of an Er-doped fiber 46 through the intermediary of an optical fiber coupler 26 is amplified by the induced emission of the exciter Er. The amplified signal light is taken out to an output end through an optical filter 56. As the transmission characteristics of the optical filter 56 has complementary wavelength dependency, the distortion of wavelength of the signal light, caused by the wavelength dependency of light amplification gain on the optical fiber 46, can be compensated. To be more precise, the variation in light amplification gain, caused by the microscopic variation of wavelength of the signal light inputted to the main body part of a light amplifier 6, can be removed by the working of the filter 56, the distortion of wavelength of the signal light outputted from the light amplifier is reduced, and the high degree of noise component generated on the light amplifier can also be decreased.
