Title: Wavelength multiplexed light source
Inventor: TANIGUCHI KOICHI
IPC: G02F1/35
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To emit multiple wave in a state where the desired number of wavelength difference and output are arranged well without using many LDs having different wavelengths by making plural difference frequency generating wavelength changing elements on which a pump light beam is made incident exist in one optical group and making a signal light beam incident on the wavelength changing element. SOLUTION: In a state where the pumping light beams P1 and P2 having different wavelengths are made incident on the respective wavelength changing elements 1 and 2, the pumping light beam P1 having a certain wavelength and a signal light beam S having another wavelength are made incident on a first element 1 in a loop and the output light beam from the element 1 is made incident on a second element 2. Then, three light beams having the different wavelengths, that is, idler light beams are newly generated in addition to the signal light beam S and the pumping light beam P1 which are made incident. Thereafter, two idler light beams having different wavelengths are additionally generated anew every time when the light beam goes through one wavelength changing element.  By repeating such conditions, in other words, by making circles around the loop, many light beams are generated from the first one signal light beam S.

Title: Ultrasonic diagnosing apparatus
Inventor: TSUNODA YOICHI
IPC: G01N29/22
Filed: 1991-06-24
Abstract: PURPOSE:To enable the judging of whether an ultrasonic probe is left alone in the air or not accurately by detecting reflection of an ultrasonic wave with an acoustic lens to control the transmission of waves from the ultrasonic probe according to an output of the detection. CONSTITUTION:When an ultrasonic probe 4 is left alone in the air, an ultrasonic wave is reflected in multiplicity with a rubber lens. At this point, a signal A is inputted into a wave form shaping section 10 and a signal B is outputted from the waveform shaping section 10. A pulse generating section 12 outputs a pulse of a signal D as the signal B becomes larger than a specified level T when a gate signal C is at 'H'. When the signal D is inputted, a pulse width judging section 13 outputs a transmission checking signal as pulse widths P1, P2 and P3 are equal. This enables accurate detection of how the ultrasonic probe is left alone in the air thereby preventing heating and characteristic degrading.

IPC: C22C5/02
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To enable brazing without impairing high grade feeling, color tone, etc., incidental to pure gold by constituting a gold solder such that Co and Ge are incorporated by a specific weight% or above and that the balance is Au by a specific weight% or above. SOLUTION: The solder is designed to contain not less than 0.5 wt.% each of Co and Ge, with the balance Au by 95 wt.% or above. Co and Ge are added for the purpose or lowering the melting point 1,063 deg.C of pure gold and increasing the strength of the filler metal itself. Both of these effects are attained by the combined addition of Co and Ge, which are required to be not less than 0.5 wt.% each. If either Co or Ge is less than 0.5 wt.%, it makes the melting point of the filler metal higher and its strength lower, preventing the use as the filler metal. Meantime, Au needs to be contained for 95 wt.% or above; otherewise, gold is degraded.
