Surface mount component placement machines are being widely used in electronic manufacturing industry for automated placement of components on printed wire boards (PWBs). Their performance is determined by their board assembly time. Factors that determine this include the machine’s architecture and placement sequence algorithm, and component locations on the board. For a given machine and a boa...

We present the experimental and astronomical results of the tunerless waveguide 810GHz SIS receiver. The Nb/AlOx/Nb junctions associated with a broadband tuning circuit, namely parallel connected twin junctions, are fabricated at Nobeyama Radio Observatory. The tuning microstrip line is made of a Nb thin lm. The lowest receiver noise temperature is 580 K (DSB) measured at 810 GHz, in which the ...

the constitutive relationships of the rubber materials that act as the main spring of a hydraulic engine mount are nonlinear. in addition to material induced nonlinearity, further nonlinearities may be introduced by mount geometry, turbulent fluid behavior, temperature, boundary conditions, decoupler action, and hysteretic behavior. in this research all influence the behavior of the system only...

The dimensional changes of 4 types commercial luting cements after setting were examined in distilled water, using a developed thermal expansion testing apparatus. The measurements were carried out under three conditions: increasing temperature (from 37•Ž to 60•Ž), decreasing temperature (from 37•Ž to 10•Ž), and constant temperature (37•Ž). The results indicated that: (1) the zinc phosphate cem...

abstract this study was carried out in japan for evaluation of the relationship between phenolic compounds and skin color indices of 3 apples cultivars including ‘fuji’, ‘jonathan’ and ‘jonagold’, in 2006. in ‘jonathan’, l* (lightness) increased with decreasing red color of skin. in ‘jonagold’, chroma increased with increasing red color. but in ‘fuji’, there was no detectable difference between...

A scanner characterization method based on an analytic spectral model was derived. Themethod firstmodeled the spectral formation of eachmedium using either Beer-Bouguer Law or Kubelka-Munk theory. Scanner digital counts were then empirically related to dye concentrations. From these estimated dye concentrations, either spectral transmittance or spectral reflectance factor could be predicted. Th...

Applying our photo technology, we succeeded in generating silver particles exceeding 10 μm by using 50 nm gold particles as catalysts, which are commonly used in commercially available influenza diagnostic kits. The amplified silver particles are 1,000 times easier to see than gold nano-particles. We have commercialized the influenza detection kit, named “FUJI DRI-CHEM IMMUNO AG cartridge FluAB...
