Abstract: A glass wool molded product comprising a layered body of glass wools is characterized in that the layered body does not contain any binder, the layered body is needle punched in a direction orthogonal to a longitudinal direction of the wools thereof, that the layered body is integrally formed, the wools have an average diameter of 3 to 7 ?m, and each of the wools has a length between 10 and 200 mm. Preferably, the molded product has a multilayer structure in a direction orthogonal to the longitudinal direction of the wools, and the average diameter of the fibers or wools of a first layer differ from each other. Preferably, a density of the second layer that of the second layer differ from each other.

Abstract: A glass run channel mountable along a window frame and made of a thermoplastic elastomer includes a base portion, a pair of side wall portions extending from the base portion, and projections that engage the window frame. A non-slip portion made of material having a larger coefficient of friction with respect to the window frame than that of the thermoplastic elastomer is provided on a face of the base portion opposite to the window frame. The non-slip portion is less slidable on the window frame than the thermoplastic elastomer, and further less slidable due to an orthogonal load produced when the glass run channel is mounted and pressed. Therefore, the glass run channel is stably maintained at a predetermined position in the window frame even if a force is exerted by sliding the window pane repeatedly.

Abstract: An object of the present invention is to reduce or prevent noise during a slide movement of a window pane for a long period of time. A plurality of projecting ridges 30 and 31 are formed on surfaces of interior and exterior sealing lips 24 and 25 of a glass run channel to be mounted on a window frame, so as to be substantially in parallel to each other along a lengthwise direction of the sealing lips 24 and 25. Each of main projecting ridges 30 and 31 is formed so that a cross-sectional shape thereof becomes substantially a scalene triangle including a longer side at a root side of each of the sealing lips 24 and 25 and a shorter side at a distal end side of the sealing lips 24 and 25.

Abstract: According to a decision threshold voltage controlling method of feeding an optimum decision threshold voltage to a clock and data recovery circuit which converts an optical input signal into an electric signal, extracts a clock component from an input data signal amplified to a predetermined amplitude, and identifies 1 or 0 in the input data signal at a timing of the clock, three decision points are suitably controlled, by selectively performing a process of controlling the spaces of the three decision points, a process of moving the three decision points with their spaces kept as they are, and a process of changing an error pulse measurement time, depending on a measurement result of the error pulse.

Abstract: A glass-run channel comprises a sectionally U-shaped body which is installed on a window frame of a door of a vehicle and a glass sealing lip which slidably contacts a windowpane 81 which is opened and closed. The rear surface of the glass sealing lip and/or the inner surface of the body are covered with a sliding-contact material formed of a material different from that of the body and having a high degree of sliding-contact performance.
