Title: Automatic chemical analysis instrument
Inventor: NAKANO KIYOKAZU
IPC: G01N35/10
Filed: 1985-01-31
Abstract: PURPOSE:To make possible the exact metering of a reagent by providing a deaerating part to a reagent dispersing line and removing preliminarily the gaseous component dissolved in the reagent before sucking the reagent into a reagent metering pump. CONSTITUTION:A vacuum pump 23 is operated and the piston of the metering pump 11 is sucked and moved where a rotor 15 of a three-way solenoid valve 7 is rotated 180 deg. toward the right after the confirmation that a reduced pressure chamber 18 attains the intended 100mmHg pressure. The reagent 22 in a reagent vessel 21 enters first a liquid feed tube 20 and in succession, the reagent enters a synthetic resin film tube 17 where the foam generated in the reagent and the gaseous component dissolved in the reagent are separated through the porous wall of the tube 17. The carry over of the foam into the pump 11 is thus prevented. The rotor of the three-way solenoid valve is rotated 180 deg. to the right when the reagent is exactly metered. The piston of the pump 11 is thereby moved to the discharge side to disperse the reagent into a reaction tube 2.

IPC: H02P9/08
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To attain an exciting device for synchronous machine which can attain cost reduction, simple constitution, and easy maintenance. SOLUTION: This exciting device involves a thyristor bridge 3 constituted of a plurality of thyristors 3a to 3f for exciting the field winding 1a of a synchronous machine 1 connected to a system side. In stopping the synchronous machine 1, a main circuit breaker 31 is opened, the thyristors 3a to 3f of the thyristor bridge 3 are ignited simultaneously, and field energy stored in the field winding 1a is discharged through all the thyristors 3a to 3f.  The resistance of a field discharge circuit at that time is almost determined by the resistance value of the field winding 1a, discharging is conducted more slowly with its discharge time constant being about 10 seconds than a conventional type whose discharge time constant is about 2 seconds, and the time of dozens of seconds, or minute unit is required for complete elimination of the field current, however, it causes no trouble in practical use.

Filed: 1991-02-08
Abstract: PURPOSE:To change brightness of illumination naturally, by outputting a driving signal to an inverter drive circuit or a transformer, based on a data series in which a power spectrum is in proportion to inverse number of a frequency.
