An upstream-side catalyst is provided at a location in close to an exhaust manifold of an engine. An HC absorbent and a downstream-side catalyst are installed in series at the downstream side. With the upstream-side catalyst put in an inactive state, the HC absorbent absorbs HC having passing through the upstream-side catalyst. After the upstream-side catalyst has been activated, HC released from the HC absorbent is refluxed to the upstream side of the upstream-side catalyst through a reflux path to be removed by the upstream-side catalyst. At that time, the ECU executes catalyst-early-warming control right after an engine start in order to raise the temperature of the upstream-side catalyst at an early time so as to shorten the time it takes to activate the upstream-side catalyst.

The invention discloses a leakage inductance energy absorption and feedback circuit of a flyback transformer and a control method thereof. The leakage inductance energy absorption and feedback circuit is integrated together and formed by a clamper tube Sc and a clamper capacitor Cc only. The leakage inductance energy absorption and feedback circuit is simple and reliable in structure. According to the control method of the leakage inductance energy absorption and feedback circuit, the clamper tube is switched on for Tc after a flyback main tube is switched off, and Tc is half of a resonance period of leakage inductance and the clamper capacitor and far shorter than the switch-off time of the main tube. The leakage inductance energy absorbed by the clamper capacitor is released to a main power circuit by means of the resonance of the clamper capacitor and the leakage inductance, so that the switched-off voltage peak of the flyback circuit main tube is lowered effectively, and the efficiency of the flyback transformer is increased. Meanwhile, by means of non-complementary connection of the clamper tube and the main tube, the switch-on time of the clamper tube is far shorter than the switch-off time of the main tube, and therefore, the absorption and feedback circuit does not affect the switching process of the main tube and is suitable for flyback circuits in any operation modes. The circuit reliability and efficiency of a miniature photovoltaic grid-connected inverter utilizing the leakage inductance energy absorption and feedback circuit can be increased greatly.

An impact absorbing device has fixed discs and rotary discs alternately and coaxially disposed. Each disc has two surfaces, and two surfaces of each pair of fixed and rotary discs face each other through a lubricant. Each surface has dimples, respectively, surrounded by concave portions. A position of each dimple in the rotary discs is differentiated from a position of any dimple of the fixed discs in a radial direction of the discs. In response to an impact given to the rotary discs, the rotary discs are rotated on the fixed discs against a frictional force between the discs to absorb the impact. During this rotation, each dimple of the rotary discs is moved along a circumferential direction of the discs, and no concave portions of the rotary discs are placed just on the concave portions of the fixed discs.

A diaper is provided in a transverse middle of a crotch region with a pad seat formed from top- and backsheets. The pad seat has a pair of extensions bifurcated from a rear end of the pad seat toward respective tape fasteners. In the course of wearing the diaper as well as during use of the diaper, a tensile force functioning to pull side flaps outward as viewed in a transverse direction of the article is transmitted to the respective extensions and pulls the pad seat so that the pad seat may be tightened so as to press a pad laid in the pad seat against the wearer's skin.

A webbing retractor having a force limiter mechanism whose energy absorption amount is large and which can reliably absorb energy. To this end, a wire is provided as an energy absorbing member having a fixing portion, a curved portion and a fit-in portion. When a spool rotates in a pull-out direction relative to a lock base, the fit-in portion is forcibly pulled-out from a fit-in hole and deformed while being strongly rubbed. Here, the fit-in portion deforms along an imaginary extended line of the curved portion. Thus, breaking of the wire due to concentration of shearing stress at one portion of the wire can be prevented.

It is an object of the present invention to increase displacement amount of a dent preventive reinforcement in an impact load application direction when an impact load is applied to an outer surface of an outer panel in a front structure of a vehicle hood.In a front structure (1) of a vehicle hood, a dent preventive reinforcement (70) is connected to an outer panel (20) and an inner panel (30).
