Abstract:
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.

Abstract:
Disclosed is a vehicle-mounted communication device that carries out radio communications with a communication device for pedestrians which is carried by a pedestrian, the vehicle-mounted communication device including: a receiver that receives pedestrian information showing whether the pedestrian belongs to a pedestrian group formed of the pedestrian and a plurality of pedestrians in the vicinity of the pedestrian from the communication device for pedestrians; a controller that judges the pedestrian information received by the receiver and issues a command to present pedestrian attention information when the pedestrian information shows that the pedestrian does not belong to a pedestrian group; and an information outputter that presents the pedestrian attention information according to the command from the controller. Therefore, the vehicle-mounted communication device enables the driver to certainly recognize the existence of a pedestrian not belonging to a pedestrian group.
Abstract:
In an image reading apparatus, it is judged whether an original sheet is either one of a first sheet type, whose sheet length is longer than or equal to a first conveyance distance and shorter than a second conveyance distance, and a second sheet type, whose sheet length is longer than or equal to the second conveyance path, the first conveyance distance being distance between a first conveyance roller and a second conveyance roller, the second conveyance distance being distance between a supply roller and the second conveyance roller. The original sheet is conveyed at a separation timing, when the original sheet separates away from the supply roller, at a speed that is smaller for a case where the original sheet is of the first sheet type than for a case where the original sheet is of the second sheet type. An image is read from the conveyed original sheet.

Abstract:
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.
