    摘要: A pulse signal is output from a position detector or the like provided on an object to be driven by the motor as the object to be driven travels, and the commutation of the motor is controlled on the basis of the pulse signal. More specifically, the object to be driven is driven by the motor, so that the travel of the object to be driven is proportional to the rotational amount of the motor, and the rotational state of the motor can be detected from the traveling state of the object to be driven, thus enabling the detection of the position of the rotor. Hence, by controlling the commutation of the motor on the basis of a detection signal from the position detector, a commutation timing can be precisely detected even if the motor is in a low speed zone.

    摘要: A method is provided for detecting a bacterial pathogen in a sample. One step of the method includes obtaining a sample and then subjecting the sample to nested PCR. The nested PCR is conducted in the presence of at least two outer oligonucleotide primers complementary to a target nucleotide sequence of the bacterial pathogen so that a first amplified product is produced. The target nucleotide sequence includes at least a portion of a 16S-23S ribosomal RNA sequence. The first amplified product is subjected to the nested PCR in the presence of at least two inner oligonucleotide primers complementary to the nucleotide sequence of the first amplified product so that a second amplified product is obtained. Detection of the second amplified product indicates the presence of the bacterial pathogen in the sample.

    摘要: A disk storage unit houses a plurality of sheet-like protective sleeves, each for storing a disk therein. Punched apertures are provided in the protective sleeves, to enable them to be bound in a binder type filing implement. An edge of each of the plurality of protective sleeves is removably affixed to a case by means of an adhesive, which can be peeled off, for example. The disk storage unit enables storage of a great number of recording media disks, such as CD's, in a limited space.

    摘要: When a rotor of a brushless motor 1 is at rest, excitation is performed three times such that excitation phase is switched each time an excitation is performed thereby to ensure that the rotor rotates. When the rotor has stopped after the third excitation, a commutation reference point is set at the rest position. A position detector outputs pulses in response to movement of an object driven by the brushless motor. The pulses output from the position detector are monitored and commutation is controlled on the basis of the number of pulses as counted starting from the commutation reference point. For example, the number of pulses output during a period starting from the commutation reference point and ending at a point of time at which commutation should be performed is measured as a predetermined number in advance. When the counted number of pulses with respect to the commutation reference point becomes equal to the above predetermined number, it is determined that a commutation timing has reached, and commutation is performed.

    摘要: A charger capable of reliably and uniformly maintaining a discharging gap formed in the vicinity of a contact portion between a charging member and a photosensitive member. A charging member 101 is arranged by supporting and fixing both ends of a flexible film 102 by means of support members 103 to 105. The film 102 forms a flexible portion oriented downwardly from fixed ends S1, S2. The film 102 is brought into contact with the member 110 to be charged in a state in which an unsupported side of the film 102 is oriented toward the downstream side in the rotating direction of the member 110 to be charged. Then, the film 102 is brought into contact with the member 110 to be charged in a contact area N, and the radius of curvature of the film 102 in a zone P2 located downstream of that zone N in the rotating direction of the member 110 to be charged becomes smaller than the radius of curvature of the film 102 in an upstream zone P1.
