In this invention, the detection result indicating physical characteristics obtained from sensor sections and associated with a to-be-detected object for which it is determined that determination of detection thereof by a high-speed detecting process is difficult to make is stored in a data storage unit. Then, in a precise examination processing section, the detecting process is effected on the non-real time basis for a to-be-detected object for which it is determined that the precise examination is necessary by the high-speed detecting process by use of data stored in the data storage unit and the to-be-detected object is distributed into a storage box corresponding to a category of the to-be-detected object as the detection result from the precise examination processing section.

A circuit board electrical connector includes a connector housing (20) having a front edge holding section (21) with a receiving groove (23) for receiving a leading edge of a circuit board (1) having a plurality of contact pads (2) on the leading edge and an aperture or notch (3) therein, and a pair of guiding sections (22) extending upward from opposite ends of the front edge holding section for guiding the circuit board; a plurality of contact elements (25) provided in the receiving groove for contact with the contact pads of the circuit board; a pair of insertion slots (28) provided in the guiding sections and having a width slightly greater than a thickness of the circuit board; at least one pair of pressure portions (29A) provided on opposed faces of one of the insertion slots such that a distance between the pressure portions is slightly less than the thickness of the circuit board so as to hold the circuit board between them; and at least one pair of engaging projections (29B) provided on the pressure portions for engagement with the notch or aperture of the circuit board when the circuit board is inserted in the receiving groove.
摘要:
A method and a system for monitoring specific channels in a WDM system involve splitting a WDM signal into multiple parallel signals, filtering the parallel signals with corresponding individually tunable filters in order to pass specific channels to each filter, and then detecting the presence of passed channels with dedicated detectors that correspond to the tunable filters. In a preferred embodiment, the initial WDM signal is demultiplexed by wavelength into multiple different transmission groups and each filter can be individually tuned over a channel range that corresponds to the range of channels within the transmission group that is directed to the filter. The preferred individually tunable filters are vertical cavity filters formed utilizing semiconductor wafer processing techniques, and the preferred photodetectors are simple low cost single-cell photodetectors.

An ultrasonic motor comprises first piezoelectric oscillators alternately arranged with first polarized regions having a first direction of polarization and second polarized regions having a second direction of polarization opposite to the first direction of polarization. The first piezoelectric oscillators undergo bending vibration in a first direction upon input of drive signals having a same phase to the first polarized regions and the second polarized regions to thereby excite the first and second polarized regions. Second piezoelectric oscillators are laminated to the first piezoelectric oscillators in a second direction generally perpendicular to the first direction for undergoing elongation and contraction vibration in the first direction. When a driving signal is applied to the first and second piezoelectric oscillators a drive force is generated by a combination of the bending vibration of the first piezoelectric oscillators and the elongation and contraction vibration of the second piezoelectric oscillators.

Radioactive stents used in angioplasty on sclerotic coronary arteries without the risk of restenosis can be produced by ion injecting 133Xe into the surfaces of stents as a nuclide that has a shorter half-life and emits a smaller maximum energy of &bgr;-rays than 32p Uniform ion injection is accomplished using an apparatus capable of uniform irradiation of the stents with 133Xe ion beams. The source of 133Xe is a nuclear fission product generated from 235U in the fuel rods in nuclear reactor.

A ferromagnetic material can be formed in a very small size on the order of an atomic size and is capable of being stably magnetized. The ferromagnetic material comprises basic unit structures each consisting of a first atom (11), a second atom (12) of the same kind as the first atom (11), and a third atom (or atomic group) (13) of the same kind as the first atom (11) or of a kind different from that of the first atom (11). In each of the basic unit structures, the atoms are arranged on a surface of a substrate so that a chemical bond (14) is formed between the first atom or and the third atom or molecule, a chemical bond (14) is formed between the second atom and the third atom or molecule, a chemical bond or an electron path (15) not passing the third atom is formed between the first and the second atom.

A chemically amplified positive resist composition contains (A) an organic solvent, (B) a base resin in the form of a polyhydroxystyrene having phenolic hydroxyl groups some of which are protected with alkoxyalkyl groups and having a weight-average molecular weight of 3,000-300,000 and a dispersity of 1.0 to 1.5, (C) a photoacid generator, and (D) a vinyl ether group-containing compound. The composition is sensitive to actinic radiation, especially KrF excimer laser beam, has high sensitivity and resolution, and forms a resist pattern having improved plasma etching resistance and heat resistance.
