Abstract: This motor is a DC motor in which the rotor is rotated by magnetic force from a permanent magnet. The rotor has a combination of two or more permanent magnets, with fixed armatures with coils on either side in the direction of the rotation shaft, enabling the motor to be built with narrow housing. It is also theoretically possible to add permanent magnet rotors and fixed armatures alternately in a straight line in the direction extending from the end of the fixed armatures, which can be presumed to achieve a greater rotational force. The DC motor described in Item 2 has a rotor consisting of three armatures consisting of steel rods with coils arranged in fixed, parallel positions around a rotation shaft. Fixed permanent magnets are arranged on the left and right side of the rotor, and a current is applied with a brush to generate rotation.

Abstract: Provided is an ignition coil which is capable of maintaining reliable insulation performance over a long period of time. A coil main body unit (BDY), which houses a primary coil (L1) and a secondary coil (L2) as well as a switching element (Q), is configured such that the coil main body unit is segmented into a case main body (10) in which a housing space is provided, and a case lower portion (20) which abuts the perimeter of the case main body, and the primary coil and the secondary coil, which are placed in the case lower portion (20), are covered by the case main body (10). The secondary coil (L2) is configured by winding a second winding (41) around a secondary bobbin (40), through which a central hole (H2) is extended in the horizontal direction, and the outer periphery of the same is covered by the case lower portion (20) and a protective cap (42) and filled with a first material.

Abstract: Collection containers (17) are heated by head conduction from a container rack (18) with a heater (19) as the heat source. When an eluting solvent is supplied into a trap column (7) by a pump (5), an eluate containing a target compound exiting from the column (7) flows through a preparative separation passage (13) and drips from a solution nozzle (13a), and this solution is separated into fine droplets by a gas stream blowing from a gas ejection nozzle (15a). When a droplet touches an inner wall of the container (17), the volatile solvent immediately vaporizes, leaving the target compound precipitated in solid forms on the inner wall. Thus, the process of vaporizing and drying the eluate to collect the target compound is completed within a short period of time. This process can be performed online and hence is suitable for laborsaving.

Abstract: A solution containing a target compound is passed through a trap column (14) to capture the target compound in the column (14). Thereafter, wash water is introduced in the trap column (14). Then, the setting of a six-port valve (7) is changed and an on/off valve (6) is opened to introduce nitrogen gas through a supply-side passage (8) in the trap column (14). In this stage, the nitrogen gas is warmed by means of a heat-exchange block (10), and the trap column (14) is warmed via a column rack (15). Any water remaining in the trap column (14) is initially thrust upwards by the nitrogen gas, to be extruded from an exit edge (14b) and discharged through a discharge-side passage (20). Furthermore, any water adhering to adsorbent or the inner wall surface of the trap column (14) is quickly vaporized and carried away by the nitrogen gas.

Abstract: A mixed liquid passage (31) is connected to a trapping passage (22) at a point upstream of a trap column (23). A mixture of a diluting liquid and an additive agent, which are respectively drawn and sent by pumps (35) and (36), is supplied into the mixed liquid passage (31). When an eluate containing a target compound is passed through the trap column (23), the eluate is diluted with the diluting liquid and hence its elution capability decreases, so that the target compound can be easily captured in the trap column (23). Meanwhile, the solubility of the mobile phase in the eluate decreases, causing not only the target component but also foreign compounds to more easily precipitate. However, their precipitation is prevented by the effect of the additive agent. Thus, clogging of the trap column (23) or pipes is prevented.

Abstract: After a target compound is captured by an adsorbent within a trap column (7) held by a column rack (8) in a substantially vertical position and the column is filled with water to wash its inside, dichloromethane is slowly introduced from an inlet end (7a) on the lower side by a pump (5). The water within the trap column (7) is pushed upward by dichloromethane and exits from an outlet end (7b), to be disposed of via a two-way selector valve (12) and a disposal passage (14). Dichloromethane elutes the captured target compound. Therefore, when the eluate, which initially consists of water, changes via an emulsion to dichloromethane, the eluate contains an adequately high concentration of target compound. At this point, the two-way valve (12) is switched to a preparative separation passage (13). As a result, a solution that is adequately free from water and yet contains the target compound can be collected into a collection container (17), and the target compound in solid forms can be quickly obtained.

Abstract: Signal wavelengths ?1, ?2, ?3 of signal light components multiplexed at signal multiplexing sections 31, 41, 51 of multiplexing stations 3, 4, 5 installed on the input end side of an EDFA 2 on an optical transmission line 1 are set such that the wavelength-dependent noise figure of EDFA 2 successively decreases from the signal wavelength ?1 multiplexed at the signal multiplexing section 31 closest to the input end of EDFA 2 to ?2 and ?3. On the other hand, the transmission length of individual signal light component before being fed into the EDFA 2 is the shortest in the signal light component at ?1 and successively increases at ?2 and ?3. Thus, the order of magnitude of input signal light power is the same as the order of highness of noise figure in EDFA 2, whereby fluctuations in S/N ratio in the resulting amplified light are reduced.
