Abstract: The open/close body drive device is capable of restarting a brushless motor, without using magnetic pole sensors, so as to securely drive an open/close body in an arbitrary direction when any of the magnetic pole sensors has failed. When a CPU (1) detects an abnormal logic as a detection pattern of the magnetic pole sensors (9), the CPU (1) determines that the sensor has failed and temporarily stops drive of a DC brushless motor (5), and a motor drive unit (4) generates a phase switching signal to prolong one of electric connection patterns for performing sensorless drive when restarting the DC brushless motor (5).

Abstract: A tilt sunroof unit has a sunroof panel provided tiltably with respect to a plane of an opening provided in a vehicular roof, an annular frame formed so as to extend continuously along an entire periphery of the opening, the annular frame being formed of a single parts in which a peripheral gutter continuing along an entire periphery thereof is integrally formed, and a lifting mechanism for connecting the sunroof panel and the annular frame, wherein the tilt sunroof unit in a subassembled state with the sunroof panel assembled thereto is assembled to the roof

Abstract: The present invention provides a panel seal structure having a seal mounted around the outer circumferential edge of a panel body, such as glass panel, covering an opening formed in a vehicle body. An upper face of the seal is set to be substantially flush with an upper face of the panel body. A lip to be contactable with an edge of the panel body is formed along the upper face of the seal, and the edge of the lip is deformed downward upon contact with the edge of the panel body. Thereby, since the edge of the lip is deformed downward, a dimensional error of the panel body is accommodated for, and the continuity between the upper face of the seal and the upper face of the panel body is enhanced.

Abstract: In a glass panel arrangement for automotive sun roof systems having a weather strip frame which is disposed substantially flush with the glass panel, a support frame made of metallic material and attached to a lower surface of the glass panel along a peripheral part of the glass panel is provided with an outer extension for supporting a part of the weather strip frame extending away from the edge of the glass panel from below so as to resist the tendency for the weather strip frame to get detached from the outer periphery of the glass panel. Therefore, the weather strip frame can be made of plastic material which has a relatively low affinity with the glass panel. In particular, if the outer extension is provided with an upwardly directed flange, not only the retaining force of the outer extension is improved but also the bending rigidity of the outer extension is improved.

Abstract: In a method of cooling a tank molded from thermoplastic plastic material, a molded tank is received from a metallic die assembly at a temperature somewhat lower than a melting point of the plastic material, the molded tank is retained in a jig frame, and cooling water is sprayed onto an external surface of the molded tank. Preferably, the method further comprises the step of blowing cooling air into the tank substantially at the same time as spraying cooling liquid onto an external surface of the molded tank. Thus, the molded plastic tank can be removed from the metallic die assembly at a relatively high temperature, and the use efficiency of the metallic die assembly can be improved. Also, because the tank is not subjected to any pressure or buoyant force, it is prevented from undesirably distorting. In particular, by blowing cooling air into the tank, the tank can be cooled even more quickly.

Abstract: The double glazed panel assembly comprises a glass holder frame which includes an inner annular glass supporting surface and an outer annular glass supporting surface which extends along an outer periphery of the inner annular glass supporting surface in a laterally spaced relationship and is raised relative to the inner annular glass supporting surface, and the outer and inner glass sheets are supported by the outer and inner annular glass supporting surfaces, respectively. Therefore, the outer peripheral part of the outer glass sheet provides an inwardly facing surface (facing the corresponding glass supporting surface of the glass holder frame) that is available as a surface for bonding onto the glass holder frame so that the outer glass sheet as well as the inner glass sheet can be firmly attached to the glass holder frame, and a required integrity of the assembly can be ensured even though the panel assembly presents a flush outer surface.

Abstract: There is provided a weather strip for use on a sunroof which can be firmly built in a seal holder even if there occur variations in molding dimensions.

Abstract: In an automotive sunroof system which comprises a fixed roof panel defining a roof opening, an inner frame defining guide rails and drain grooves, a moveable panel guided along said guide rails via sliders and a slide and tilt mechanism for effecting a slide and tilt motion of the moveable pane, a terminal member is attached to each front corner of the inner frame to serve several purposes such as a closure member for the guide rail, a stopper for the forward travel of one of the sliders, a member for retaining the fore-and-aft movement of the moveable panel, and a support for a wind deflector device.

Abstract: There is provided a weather strip for use on a sunroof capable of preventing squeak noises being generated in advance between a hollow seal part and a roof panel during traveling of a car by allowing the hollow seal part to satisfactorily follow vibrations of the roof panel. The weather strip ensures sealing property between a roof glass mounted on the sunroof of a car and a roof panel and comprises a built-in base part attached to the roof glass, and a hollow seal part composed of continuous ends integrally formed with the built-in base part and having substantially a circular cross section, a tip end contact part elastically contacting the roof panel, wherein thicker parts protruding inward and being continuous with the built-in base part are formed on the continuous ends of the hollow seal part and protrusions protruding inward are formed on substantially middle parts between the continuous ends and the tip end contact part.

Abstract: A sunroof apparatus with a sliding panel freely opening and closing an opening of a roof in a vehicle, a movable drain arranged below a rear end in the panel and moving forward and rearward interlocking with a forward and rearward movement of the panel, and a sunshade covering a lower side of the sliding panel and freely opening and closing. A holding means for the sunshade is constructed by forming sliding grooves in frames in both sides extending along a longitudinal direction in a side of a passenger room of the opening, forming a notch at a predetermined position of the groove L3 fitting front and rear sliders to which the sunshade is mounted, and integrally forming an engagement piece made of elastic member and fitted to the notch in the rear slider.

Abstract: In a plastic fuel tank comprising a main body having a laminated structure including a layer made of gasoline barrier material and an outer layer made of common plastic material, and a component part adapted to be secured in a hole formed in the tank main body, the component part includes at least a part made of weldable plastic material and welded to a part of the tank main body made of common plastic material, and a part made of gasoline barrier material and extending across said component part so as to separate the interior and exterior of the tank main body from each other. The two parts of the component part may be permanently integral to each other or may be detachably attached to each other. Thus, the welding strength can be ensured while the permeation of HC through the part made of the common plastic material can be avoided.
