Abstract: A tracking error detector receives laser light that is irradiated onto tracks on a disc surface and that is reflected from the tracks by using a light-receiving device having divided portions, binarizes signals output from the light-receiving device having divided portions in accordance with the amount of tracking error by using a signal processing circuit including a binarization circuit, and outputs a tracking error signal for tracking control on the basis of a phase difference between the binarized signals. The tracking error detector includes an inter-signal amplitude difference adjustment circuit for determining an amplitude difference between signals output from the light-receiving device, for adjusting the amplitude difference between the signals, the amplitude difference being binarized by the signal processing circuit, for equalizing the phase offset of each of the signals, and for suppressing the phase offset with respect to the tracking error signal.

The display panel case houses the display panel such that the display panel can display an image. The display panel case has a protrusion portion formed at a first end. The main body section is disposed on a second surface and has an input section and a depressed portion. The depressed portion is formed at a second end of the second surface and has a pierced portion and a housing portion. The pierced portion is formed from the second surface to an opposite surface thereof such that a battery is attached to the pierced portion. The housing portion axially houses the protrusion portion on a side opposite to the input section with respect to the pierced portion.

A first vibrator supports a power unit relative to the vehicle body and directly vibrates the vehicle body. A second vibrator directly vibrates air inside the vehicle body. A drive control unit performs calculation on the basis of a detecting signal from the vibration sensor and controls the first and the second vibrators on the basis of the result of the calculation so that the vibration of the solid element and the vibration of air inside the vehicle body are damped. The vibrator control ratio of the first and second vibrators is changed according to the condition of a predetermined factor of the vehicle.

Abstract: An edge trim and weather seal assembly for a movable sun roof of a vehicle comprises an edge strip secured in use around an edge of a sun roof panel by means of a bonding agent, and a seal strip mounted on the edge strip to form a weather seal with the vehicle roof opening. The edge strip has top and bottom flanges overlying upper and lower edge portions of the sun roof panel and secured thereto by the bonding agent, and a recess or well portion in the bottom flange receives excess bonding agent and prevents its spillage out onto the exposed part of the sun roof panel. The seal strip has a locating edge portion for engaging the recess in the bottom flange of the edge trim to retain the seal strip on the edge trim.
