    摘要： A preload measuring apparatus to measure the preload of a rolling bearing that includes a bearing support, a pressurization device, an excitation device, a vibration sensor, and a control section. The bearing support supports a rolling bearing by supporting both ends of a shaft inserted into an inner ring of the rolling bearing. The pressurization device loads a predetermined weight in the axial direction onto the rolling bearing. The excitation device applies vibration onto the rolling bearing by the drive of the piezoelectric elements. The vibration sensor detects the vibration generated on the rolling bearing by the vibration application of the excitation device. The control section operates the excitation device in the situation that the pressurization device presses the rolling bearing, and obtains the resonance frequency by the output signal from the vibration sensor and calculates the preload of the rolling bearing according to the obtained resonance frequency before the predetermined weight as loaded.

    摘要： A process for preparing nitrogen-containing isotropic pitch, comprising the steps of mixing a petroleum heavy oil, a nitrating reagent and water to prepare a homogeneous dispersion, thereby contacting the petroleum heavy oil with the nitrating reagent in the homogeneous dispersion state to prepare a crude nitrated heavy oil, and subjecting the crude nitrated heavy oil to refining, thermal polymerization and vacuum distillation. According to the process of the invention, a petroleum heavy oil containing a large amount of light oil components and being liquid at ordinary temperature, from which pitch has been hardly prepared conventionally, is used as a starting material for preparing pitch, and there can be obtained nitrogen-containing isotropic pitch of homogeneity and high quality having a desired softening point of from a low softening point to a high softening point, though such pitch was unable to be obtained so far.

    摘要： While maintaining a shaft in a fixed state, an outer ring is rotated. Vibrations of the shaft are detected by a first vibration pickup and a second vibration pickup. Detection signals of both the vibration pickups are delivered to a frequency converter via amplifier, respectively. The frequency converter determines, by Fourier transformation, the rotation frequency of the outer ring, the revolution frequency of balls and the resonance frequency of the double-row ball bearing. A first computing assembly then calculates the contact angle and bearing rigidity, and a second computing assembly calculates the preload.

    摘要： An image reading device includes a conveying unit, reading unit, and a control unit. The conveying unit conveys successive two sheets along a conveying path such that a gap is formed between the successive two sheets. The reading unit reads a sheet conveyed at a reading position in the conveying path. The reading unit has a light source and light-receiving unit. The control unit controls the light source to emit light at a first light intensity for a sheet that has reached the reading position. The light-receiving unit receives light reflected by the sheet present at the reading position. The control unit further controls the light source to emit a light at a second light intensity lower than the first light intensity during a period of time from when the reading unit has been read the preceding sheet to when the reading unit begins reading the subsequent sheet.
