There is provide a pneumatic radial tire for heavy loads capable of more effectively preventing a breakdown due to separation of a rubber chafer in an area corresponding to a bead heal portion than before. A pneumatic radial tire 10 for heavy loads has a pair of bead portions 12, a bead core 14 which is embedded in each of the bead portions 12, a radial carcass 16 extending from one bead portion 12 to the other bead portion 12 and turned around the bead core 14 from an inner side to an outer side of the bead portion 12 in a width direction of the tire to be anchored, a rubber chafer 22 disposed over the radial carcass 16 in the opposite side of the bead core 14. An angle θ formed by a steel cord 24S of the wire chafer 24 provided inside of the bead portion 12 outside of the radial carcass 16 and a carcass ply cord 16S of the radial carcass 16 is optimized depending on shear strain generated in the rubber chafer 22 so as to effectively preventing a breakdown of the rubber chafer 22 due to separation in an area corresponding to a bead heal portion 26.

A pneumatic tire includes: a pair of bead portions 11; bead cores 12 each having a polygonal configuration in cross section; a radial carcass 13 having respective ends thereof wound around the corresponding bead cores from the inner side to the outer side of the tire; one layer of wire chafer 14 disposed on the outer side of the radial carcass 13 with respect to the bead core 12; and a rubber chafer 16 disposed in a contact area between the bead portion 11 and a prescribed rim R, wherein, in a cross section of the tire assembled with the prescribed rim R, the angle formed by the bottom side 12a of the bead core with respect to a bead seat Ra of the prescribed rim R is set in the range of 0±2°, and a portion, on the tire outer surface side, of a spiral filament or an outermost layer filament of steel cords 15 constituting the wire chafer 14 extends at an angle in the range of 90±5° with respect to the extending direction of ply cords constituting the radial carcass 13.

The present invention presents a motor drive device capable of detecting jamming accurately without falsely detecting jamming when a movable part contacts with other members. Jamming by a backrest is detected by judging whether the value of a period of one pulse P1 and a period of the next pulse P2 (P2/P1) integrated for 150 times (integrated value: 150) exceeds a specified threshold (160) or not. Accordingly, if the backrest rubs against a backrest of an adjacent seat, and the motor speed suddenly drops for a short period, such “warp” is not falsely detected as jamming, and only actual jamming can be detected securely.

An apparatus is provided that easily realizes a video recording and playback according to a taste of the user based on summary information prepared from voice/video information of TV broadcast programs. For this purpose, a seek bar is provided which, based on the summary playback information generated by the summary information generation unit for summary playback, distinguishes the time bands to be played back from the time bands to be skipped by displaying them in different colors. Also a control unit is provided which allows for changing the summary playback time and for selecting between the playback enable and disable.

An electrophotographic image forming system having a form cassette for storing forms, a transfer unit for forming an image, a feeder for feeding the forms to the transfer unit and a fusing device for fusing transferred image of the form. The electrophotographic image forming system provides in a path for feeding the form with unfused colored particles (toner) deposited thereon, a form guide so as to contact the non-printing area of the surface of the form with unfused colored particles (toner) deposited thereon.

A waterproof power window apparatus comprises: a driver-seat switch unit; an other-seat switch unit; and a bus line allowing communication to be established between the driver-seat switch unit and the other-seat switch unit. The driver-seat switch unit has: a first controller; a first driving unit for opening and closing a window at the driver seat in a window-sliding operation; an other-seat-window-opening and closing switch; a first submergence-detecting unit; and a first power-supply unit connected to the bus line and provided with a control terminal connected to the first control unit and the first submergence-detecting unit. The other-seat switch unit has: a second control unit; a second driving unit for opening and closing an other-seat window in a window-sliding operation; a second submergence-detecting unit; and a second power-supply unit connected to the bus line and provided with a control terminal connected to the second control unit and the second submergence-detecting unit.

The linear guide device has a structure in which a solid lubricating film is applied on the ball guide grooves of the main rail and the ball circulating paths of the slider, and the surfaces of the balls housed to be rotatable and movable in the ball circulating paths, are formed porous. Thus, when the slider is urged to move with respect to the main rail, and the balls rotate and move within the ball circulating paths, the balls are brought into contact with the solid lubricating films on the ball circulating paths and the films on the ball guide grooves of the main rail. Due to the effect of the surfaces of the balls, the solid lubricating film is transferred onto the surfaces of the balls, thus achieving solid lubrication.

A screw shaft, a nut, and a conduit member are made of metal material, and a solid lubrication film is coated on inner walls of thread grooves thereof and a ball circulation path of the conduit member. Where d1 is the inner diameter of the ball circulation path of the conduit member, d2 is the groove diameter of the screw shaft, d3 is the diameter of each ball, and h1 is a clearance between the screw shaft and the end portion of the thread groove (as well as the end portion of the conduit member), respective members are arranged so as to satisfy relations of (.vertline.d1-d2.vertline./d3).ltoreq.1/40 and h1/h3.ltoreq.1/40. As a result, it is possible to provide a ball screw mechanism in which film-transfer lubrication is achieved between the members and the durability and precision are improved.

A plurality of chambers are partitioned in a muffler by a baffle board. The muffler is provided with an exhaust gas passage for discharging exhaust gas outside the muffler via these chambers and a valve that bypasses a part of the exhaust passage. This valve opens according to the exhaust gas pressure. Also provided are a mechanism for pushing the valve in a closing direction, and a mechanism for damping the shock when the valve closes. Thus, valve closing noise is suppressed, and exhaust gas noise is further suppressed.
