The trifluoromethylketone derivatives (I) and pharmaceutically acceptable salts thereof have a human leukocyte elastase inhibiting activity and are useful as human leukocyte elastase inhibitors for treating or preventing degenerative diseases. The trifluoromethylketone derivatives (I) have the following formula: ##STR1## wherein R.sup.1 is C.sub.1-6 alkyl which has one or two substituents selected from carboxy, esterified carboxy and di-C.sub.1-6 alkylcarbamoyl; phenyl(C.sub.1-6) alkyl, the phenyl moiety of which may have halogen or nitro or amino substituents and the alkyl moiety of which may have carboxy or esterified carboxy substituents; halo-phenyl; morpholino; or morpholino(C.sub.1-6) alkyl,R.sup.2 and R.sup.3 are each C.sub.1-6 alkyl,X is -- or --NH--, andY is ##STR2## and pharmaceutically acceptable salts thereof.
摘要:
An optical encoder having a structure for preventing water or the like from adhering to a V-shaped groove of a code plate of the encoder. The optical encoder has a protective plate made from an optically transmissive material, the protective plate being positioned adjacent to a surface of the code plate on which the V-shaped groove is formed.

The present invention relates to an optical sender applicable to WDM (wavelength division multiplexing), and a primary object of the present invention is to prevent interchannel crosstalk in WDM. The optical sender includes a light source for outputting a light beam, an optical modulator for modulating the light beam in accordance with a main signal to output an optical signal, and a unit for shutting down the optical signal when receiving at least one of a power alarm relating to on/off of power supply and a wavelength alarm relating to the wavelength of the light beam.

The invention aims to reduce an error occurring due to the mounting condition of an acceleration sensor. In the case of a two-axis sensor, an angle θ is calculated from outputs (x′, y′) that the acceleration sensor produces when known accelerations (x, y) are applied, and the angle θ is stored in a storage device contained in a casing in which the acceleration sensor is housed. In the case of a one-axis sensor, the ratio of the magnitudes of accelerations is stored. The acceleration detected by the acceleration sensor is compensated by using the value stored in the storage device.
摘要:
A rotary disc for use in a rotary encoder includes a signal generation section having a pattern formed thereon to generate a signal indicative of a rotational angle/phase. The signal generation section has a peripheral surface, which is provided with a linear portion usable as an indicator indicative of the rotational angle/phase represented by the signal generation pattern on the signal generation section. A robot hand is employed to hold the linear portion and attach it through an attachment portion of the rotary disc to a rotor shaft of a motor.
