摘要:
A semiconductor substrate includes a substrate, an insulating layer, and a semiconductor layer. The insulating layer is over and in contact with the substrate. The insulating layer includes at least one of an amorphous metal oxide and an amorphous metal nitride. The semiconductor layer is over and in contact with the insulating layer. The semiconductor layer is formed by crystal growth.

摘要:
Alkyl (or aralkyl) .alpha.-isocyanoacetate is condensed with a trihalogenoacetic aldehyde or its hydrate in the presence of an amine to give trans-4-alkoxycarbonyl(or aralkyloxycarbonyl)-5-trihalogenomethyl-2-oxazoline. The oxazoline compound is hydrolyzed under acidic conditions to give threo-.gamma.,.gamma.,.gamma.-trihalogenothreonine, which is then subjected to catalytic or electrolytic reduction. The above-mentioned reactions can be carried out stereoselectively and threo-threonine is thereby obtained without by-products such as allo-threonine.

An insulation degradation diagnostic device (1a) comprises a current transformer (7a), a first amplifier (15), a first high-pass filter (17), a low-pass filter (19), a second amplifier (20), a second high-pass filter (21), and a discharge judgment section (30). The current transformer (7a) has a filtering function with an amount of attenuation of −60 dB or less and a slope characteristic of −5 dB/oct or less at a commercial frequency and detects a current flowing through a grounding conductor (5). The first amplifier (15) amplifies a current signal from the current transformer (7a). The first high-pass filter (17) removes a low frequency component from an amplified current signal. The low-pass filter (19) removes a high frequency component from a current signal from which the low frequency component has been removed. The second amplifier (20) amplifies a current signal from the low-pass filter (19) to a predetermined level. The second high-pass filter (21) extracts a signal corresponding to a discharge current caused by a partial discharge from the current signal amplified in the second amplifier (20). The discharge judgment section (30) judges whether or not a partial discharge has occurred in a cable (2) based on the signal extracted in the second high-pass filter (21).
摘要:
A robot arm apparatus includes an arm mechanism including a base member and a link pivotally connected to the base member for pivotal motion in a horizontal plane through a rotational shaft. The link holds a regular circular transport object at its distal end. The apparatus also includes an edge detector, provided on the base member, that detects two edges of the regular circular transport object as the link pivotally rotates with respect to the base member, a pivotal angle detector that detects a pivotal angle of the link with respect to the base member, and a center position calculator that calculates a center position of the regular circular transport object with respect to the link. The calculation is based on two pivotal angles detected by the pivotal angle detector when the edge detector detects the two edges of the regular circular transport object.
