    • A motor includes a shaft including upper and lower shaft members spaced axially away from each other. A shaft connecting member made of electrically insulating material is arranged axially between the upper and lower shaft members. The shaft connecting member is provided with fitting portions to which the upper and lower shaft members are to be fitted. While the upper and lower shaft members are secured to the shaft connecting member, the rotor magnet is integrally formed with the upper and lower shaft members and the shaft connecting member. With this configuration, an axial electric current is prevented from flowing through the shaft by the shaft connecting member.
    • 马达包括轴,该轴包括彼此轴向间隔开的上轴和下轴构件。 由电绝缘材料制成的轴连接构件被轴向布置在上部和下部轴构件之间。 轴连接构件设置有配合部分,上轴和下轴构件将被配合到该配合部分。 当上下轴构件固定在轴连接构件上时,转子磁体与上下轴构件和轴连接构件一体地形成。 利用该结构,能够防止由轴连接部件轴向流过轴。

    • Disclosed herein is an ink set for use in ink-jet recording, which comprises at least 2 ink compositions the solid content concentrations of which are different by more than 2% by mass. The at least 2 ink compositions each comprise an aqueous medium, a pigment and a dispersant for dispersing the pigment. The dispersant is an amphiphilic block copolymer having an A segment that is a hydrophobic segment, a B segment that is a nonionic hydrophilic segment, and a C segment that is an ionic hydrophilic segment. The number of unit structures of the B segment of the amphiphilic block copolymer contained in each of the at least 2 ink compositions is smaller in the amphiphilic block copolymer contained in the ink composition having a relatively high solid content concentration than in the amphiphilic block copolymer contained in the ink composition having a relatively low solid content concentration.

    • A jointing holder for an optical module for single-fiber bidirectional communication comprises a unitarily structured cylindrical body that has the following portions: (a) an optical fiber-fixing portion for securely holding an optical fiber for transmitting multiwavelength light bidirectionally, (b) a semiconductor laser-fixing portion for securely holding a semiconductor laser for emitting outgoing light λ1, (c) a photodiode-fixing portion for securely holding a photodiode for receiving incoming light λ2, (d) an optical path-forming space for optically coupling the optical fiber, the semiconductor laser, and the photodiode, and (e) in the optical path-forming space, an optical filter-fixing face for securely holding an optical filter for separating multiplexed wavelengths. The jointing holder enables the optical module to reduce the number of components, to be miniaturized, and to reduce the dimensional deviation at the time of the assembly, enabling high-precision assembly. An optical module for single-fiber bidirectional communication incorporates the jointing holder.
