Title: Inverter divece
Inventor: TANAKA HIROICHIROU
IPC: H02M7/48
Filed: 1977-09-20
Abstract: PURPOSE: To secure by a simple means the output voltage of an inverter in case of instant suspension of ac input power by connecting dc constant voltage source through dc to dc converter in parallel with the variable voltage direct current link of a forward and backward converter.  
     CONSTITUTION: A dc constant voltage source 40 is connected through dc to dc converter 30 in parallel with the dc link of an inverter and a floating charge use battery 50 is also connectrd thereto in necessary. If instant suspension of power may be occurred in ac input power source, a forward converter 10 is halted by a signal for detecting the instant suspension of the power and the dc to dc converter 30 starts so that the voltage on converter 30 is equivalent to a value of the dc link volttage. Next, the signal detects recovery of the ac input power source, the dc to dc converter 30 is halted by the recovery signal and the forward converter 10 starts with the phase corresponding to the dc link voltage. As a result, the voltage applied to a motor 90 can be operated without influence from the instant suspension of power in the ac input source

IPC: G01J3/45
Filed: 1982-06-29
Abstract: PURPOSE:To prevent lowering of the measuring accuracy due to phase errors by automatically adjusting a sampling signal to the zero point of the optical path difference. CONSTITUTION:Sampling of an interferogram signal (b) is done at level values D1-Dn and the sampled data is stored into a memory circuit MEM. Then, data Dm-1 and Dm+1 before and after the maximum value Dm are determined and when the difference between both the data is larger than the allowable errors, data to be outputted to a D/A converter DA is increased or decreased by a unit value. Output voltage of the DA is applied to a voltage controlling variable resistance element to change the resistance value, whereby output pulse of a monostable multivibrator MV is varied to adjusting the timing of the sampling. This operation is repeated until the difference between Dm-1 and Dm+1 falls below the allowable errors. This enalbes the zero-point adjustment at a required accuracy.

Title: Stainless steel plated with noble metal
Inventor: SHIGA SHIYOUJI
IPC: C23C18/44
Filed: 1980-08-19
Abstract: PURPOSE: To improve surface characteristics such as corrosion resistance, electrical connecting property, solderability or the like by interposing the intermediate plating layer of a specific metal or an alloy between a noble metal plating layer and stainless steel.  
     CONSTITUTION: After the surface of stainless steel is activated, an intermediate layer comprising one or more of Zn, Cd, Sn, In or an alloy thereof is formed by plating. If necessary, on said plated layer, further, a secondary intermediate layer comprising one or more of Ni, Co or an alloy thereof is provided and noble metal plating such as Au, Ag, Pt or the like is applied thereon. Because said first intermediate layer is less noble than stainless steel in an electrolytic corrosion system, said stainless steel is subjected to cathode corrosion proofing. Further, the secondary intermediate layer prevents deterioration of the noble metal acting as a diffusion barrier. Therefore, the resultant noble metal plated stainless steel is suitable for a material for an electronic and an electric parts.
