Title: Gold for electronic parts or gold alloy plating material
Inventor: ASAHARA HAJIME
IPC: C25D5/12
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To improve heat resistance and corrosion resistance by forming the material which has an alloy plating intermediate layer containing a specific ratio of P and consisting of the balance Ni and inevitable impurities and consists of a surface layer plating of Au or Au alloy. SOLUTION: The intermediate layer contains 0.05 to 20 wt.% P. Or the intermediate layer may contain P and B at 0.05 to 20 wt.% and Co at 5 to 60 wt.% in total. P and B form a stable film in a pinhole part by their own oxidation, thereby suppressing the oxidation and corrosion of Ni and acting to prevent the diffusion of Ni via the pinhole. Consequently, the occurrence of increase in the contact resistance of the Au or Au alloys with each other by heating and the deterioration in soldrability are substantially prevented. Co has an effect of suppressing the diffusion of Ni into the surface layer. The thickness of the intermediate layer is preferably specified to 0.01 to 1.0 μm. If inserting and removing properties are also desired to be improved, the execution of an ordinary sealing treatment by various kinds of sealing treating liquid of is recommended.

Title: Noise reduction device
Inventor: IKEDA OSAMU
IPC: H03H17/04
Filed: 1992-05-12
Abstract: PURPOSE:To reduce effectively noise without use of an expensive high performance A/D converter. CONSTITUTION:A coefficient calculation circuit 22 discriminates an input level from a 2nd-order integration low pass filter 21, and when the level is less than a 1st setting value, filter coefficients a, b, c given to variable low pass filters 13, 18 are varied to change it cut-off frequency. Thus, a high frequency including much of noise is cut off effectively. Furthermore, when the input level is decreased more than a 2nd setting value smaller than the 1st setting value, a gain coefficient (d) given to the variable low pass filters 13, 18 is changed in response to the input level to decrease the gain itself of the filter. Thus, noises (hiss noise for example) is more effectively eliminated at an area where the input level is very low.

Title: Ultrafluorescent light source, optical waveguide used as ultrafluorescent light source, optical apparatus, and unidirectional ultrafluorescent light source
Inventor: DIGONNET MICHEL J F
IPC: H01S3/067
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To practically increase emission of preferred polarized light from one of first or second end of a waveguide by disposing a polarizer at a specified position along a fiber. SOLUTION: A fiber 200 includes a polarizer 240. Optical power of one polarized light is reduced, when the polarizer 240 is disposed at a fixed position along the fiber 200. Position of the polarizer 240 along the fiber 200 has conspicuous effect on the output signal from the fiber 200 to cause polarization thereof. When the polarizer 240 is positioned along the fiber 200, the optical output intensity is substantially doubled along with the uneliminated polarization mode. Consequently, an intensively polarized output signal is applied to an end 230 of the fiber 200 and the power (i.e., intensity) can be doubled as compared with original one. According to the arrangement, emission of preferred polarized light from one of first or second end of a waveguide can be increased practically.

Filed: 1981-07-31
Abstract: PURPOSE:To pervent the effect of a time delay caused by the working of a transistor, by actuating a transistor in an active region to control the working of another transistor that produces an output signal. CONSTITUTION:The collector voltage of a transistor TRQ2 is clamped by the emitter voltage of a TRQ5. The base voltage of the TRQ5 is set constant by the collector voltage VL of a TRQ6 of a constant voltage circuit 31. Thus it is always possible to actuate the TRQ2 in an active region by setting each resistance value of the resistances R3 and R4 at a prescribed value. As a result, a current I2 flows to the collector of the TRQ2 at a time point when an input signal P has a rise temporarily, and at the same time a current I1-I2 is supplied to the base of a TRQ4. Thus the voltage VO has a rise with no time delay, and an output signal OUT has a fall. The signal OUT has a rise with no time delay also when the signal P has a fall.
