Abstract: An object is to enhance workability in attachment in a sound generating apparatus that generates sound by vibrating a vibration plate with a vibrator while ensuring acoustic performance as good as that achieved by fastening with fine screw threads. Workability in attaching operation is improved while ensuring acoustic performance as good as that provided by fastening with fine screw threads, by providing first fixing portion that brings engagement portions into screw engagement with each other by rotation by a predetermined angle that can be attained by a user without taking his/her hand that holds a coupler off it and second fixing portion for fixing the coupler to a bracket so as to prevent the coupler from rotating relative to said bracket in a direction to loosen the engagement achieved by said first fixing portion.

Abstract: The invention provides a drain mechanism of a fluid filter in which a heated fluid is not splashed on a worker at a time of discharging the fluid such as a time of exchanging an element, and can inhibit dusts or the like from being mixed from an external portion at a time of normal use. A drain mechanism 7 of the present invention is provided with a cap 3 engaged with a case 2 and having a drain hole 15, a drain member (a drain plug 20) detachably mounted to the cap from an outer side thereof and closing the drain hole, a valve member 25 provided in an inner side of the cap and closing the drain hole, and an elastic means (a spring 11) for energizing the valve member in a direction of closing the drain hole. In a state in which the drain member is detached from the cap, a residual fluid within a housing is discharged by a tubular draining jig 30 inserted to the drain hole.

Abstract: A muffler which reduces noises of a wide frequency band with a simple structure. Sound waves of an intake duct enter into and are received in a resonance box via a branch pipe. At the branch pipe, a movable body slidingly abuts a peripheral portion of an opening of a cut-out portion. Due to the movable body rotating, a range of opening/closing of the cut-out portion is changed, and a length of a neck portion formed by the branch pipe and an arc-shaped plate, and a lateral cross-sectional surface area of a distal end of the neck portion, are changed.

Abstract: A trimming material for an automobile includes a surface skin material, a base material, and a colored resin film interposed between the surface skin material and the base material. The surface skin material and the base material are bonded to each other via the resin film. The resin film includes a surface-side adhesion layer on the side of the surface skin material, a base-side adhesion layer on the side of the base material, and a barrier layer interposed between the surface-side adhesion layer and the base-side adhesion layer and bonded thereto. The barrier layer is made of non-gas and liquid permeable material that is not melted at a temperature that causes the surface-side adhesion layer and the base-side adhesion layer to be melted.

Abstract: An oil filter has a drain hole, which is internally blocked with a valve member. When oil remaining in the oil filter is drained, a drainpipe is inserted into the drain hole, so that the valve member is displaced and remaining oil is drained from the drain hole. This valve member has an annular recession to steadily support an upper end of the inserted drainpipe. Therefore, gripping force of the drainpipe is enhanced without decreasing draining performance. The drainpipe and the oil filter are connected with each other via a seal member that is provided to the oil filter. The drainpipe 80 has a removing means that holds at least a part of the seal member to pick the seal member off the oil filter, when the inserted drainpipe is detached from the drain hole. Thus, the seal member can be removed simultaneously with the drainpipe from the oil filter.

Abstract: A nonwoven fabric for a filter excellent in cleaning efficiency and trapped matter retention volume is constructed by two or more different kinds of fibrous layers placed one over the other. The nonwoven fabric has an average pore size from 30 ?m inclusive to 60 ?m inclusive and a total pore area at 0.011 cm2/cm2 or more with respect to an entire surface of the nonwoven fabric. The average pore size is calculated according to a bubble point method as defined in ASTM F-316-80 with use of a Coulter Porometer II.

Abstract: An intake module for a vehicular engine has a casing that is constructed of an air cleaner housing portion and an electronic control unit (ECU) housing portion. The air cleaner housing portion that houses an air cleaner is mounted on the engine. The ECU housing portion that houses an ECU is connected with the air cleaner housing portion. A plurality of reinforcement ribs is formed on an outer periphery of the ECU housing portion.

Abstract: A drain structure for a fluid filter includes a cap internally forming a drain hole. The cap receives a valve member urged by an urging means in a direction, in which the valve member blocks the drain hole. Normally, the drain hole is blocked with a drain member. When fluid is drained from the drain hole, the drain member is removed from the drain hole, and a drain tool is inserted into the drain hole, so that the drain tool displaces the valve member in a direction, in which the drain hole is unblocked. The drain tool has a hooking portion that can hook to a hooked portion provided to the cap by axially rotating the drain tool inserted into the drain hole of the cap. Thus, the drain tool can be connected with the cap while the hooking portion is supported by the hooked portion.

Abstract: A shut off valve is provided in an intake line farther upstream than a throttle valve of the intake passage and farther downstream than an air cleaner. This shut off valve is opened by a signal or the like from an ECU when an engine is operating. Further, the shut off valve closes when the engine is stopped so as to suppress evaporative fuel inside the intake passage from flowing outside through the air cleaner. The evaporative fuel trapped inside the intake passage passes through a bypass passage that provides communication between the intake passage and the canister, and is then adsorbed with an adsorbent in the canister. A blow-by passage is also connected to the intake passage that is closed off by the shut off valve. Because the blow-by passage is closed off by a blow-by valve, which is closed during normal operation when the engine is stopped, sticking of the shut off valve and the throttle valve and the like due to the inflow of blow-by gas into the intake passage is inhibited.

Abstract: The invention provides an interior member for a vehicle which has a sufficient noise absorbing property, prevents a thermoplastic resin from leaching out from a base material and prevents a surface of a skin material, that is, a design surface from being soiled, and a method of effectively manufacturing the interior member for the vehicle.

Abstract: An adsorbent for adsorbing fuel vapors is disclosed. The adsorbent is to be disposed in an inlet system of an internal combustion engine. It has pores, and 50% by volume or more of the pores have a pore diameter falling in a range of from 1.4 to 2.8 nm. It exhibits a unit pore volume of 0.3 mL or more with respect to 1 mL thereof. It is formed as a particle. It exhibits high performance on adsorbing fuel vapors, and shows high durability even when it is used for long period of time.

Abstract: A throttle valve is opened after stopping an engine to prevent the valve from sticking. Then, when a temperature of the valve has become lower than the polymerization temperature, the valve is closed to seal the vapor of the HCs in a surge tank downstream. Changes in the temperature of the valve are, for example, estimated based on a temperature of an intake air detected by an intake temperature sensor.

Abstract: An intake device for an internal combustion engine has: a first intake pipe which is connected to the engine so as to conduct an intake air to the engine, and which has an opening portion that is provided in an upstream-side lower portion of the first intake pipe located at an upstream side in a flowing direction of the intake air; and a second intake pipe which has a downstream-side end portion that faces an upstream-side end portion of the first intake pipe, with a gap formed therebetween, and which conducts the intake air to the first intake pipe. An unburned gas reflux passage is provided for conducting an unburned gas from the engine to the first intake pipe. A container surrounds the gap and the opening so as to receive the unburned gas flowing from the opening portion. Thus, it becomes possible to prevent release of unburned gas into the atmosphere by performing a simple process on a conventional structure.
