Title: Antenna multicoupler
Inventor: SHINDO MASAHIRO
IPC: H03H9/72
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To attain miniaturization and light weight by combining a dielectric filter having a steep band block characteristic with a band pass type surface acoustic wave filter with a comparatively low loss. SOLUTION: A radio wave arrived in an antenna 1 is received by a reception filter 3 via a branching circuit 2, a transmission band signal (Tx) is blocked by a band stop dielectric filter 4 and only a reception band signal (Rx) is passed. Furthermore, the reception band signal (Rx) is given to a band pass surface acoustic wave(SAW) filter 5 provided with a matching circuit connected in cascade to the filter 4 and having a high frequency pass characteristic and the signal Tx is attenuated. Through this constitution, the signal Tx with a high power level outputted from a transmission filter 6 is not directly applied to the SAW filter 5, and ternary intermodulation distortion generated in the filter 5 receiving the signal Tx with a high power level is reduced and the small sized multicoupler is obtained.

Abstract: PURPOSE:To prevent the influence of change of ambient temperature on the accuracy of positioning of a head by bringing a bearing into contact with one side in the same direction of bearing fixing holes on both sides of a carriage or making the bearing eccentric to bring it very close to the side. CONSTITUTION:An adhesive 6 is filled between upper and lower bearings 4, 5 loose fitted to upper and lower housings 2, 3 of a carriage 1, and head positioning is made by bonding the fixing upper and lower bearings 4, 5 thrusting them in the same direction of upper and lower housings 2, 3 to make them eccentric.

Title: Crack inspection method and apparatus of semiconductor device
Inventor: TAKABAYASHI MEIJI
IPC: G01N27/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To easily detect a crack in a semiconductor junction, by a method wherein a voltage which varies in waveform with time is applied to the semiconductor junction, and the waveform of a current flowing through the semiconductor junction is observed. SOLUTION: A voltage which varies in waveform with time is generated by a current waveform generator 902 and applied to a semiconductor device 905 as an object of measurement. A current flowing through the semiconductor device 905 is detected by a current detector 903, and the waveform of a current is displayed on a current waveform display 904. When a crack is present, a recombination center of carriers is formed, and minority carriers are decreased in life and lessened in diffusion distance. By this setup, a semiconductor junction is lessened in diffusion capacity, so that the waveform of a forward current is lessened in crest value, and also the crest value of a backward current gets small. A current waveform changes also in width.  Therefore, these changes in a current waveform are observed through the current waveform display 904, whereby it is easily judged whether a crack is present in a semiconductor junction or not.
