In a vehicle having an air cleaner for cleaning incoming intake air supplied to an engine, a stepped surface is formed on at least one of a plurality of walls of an air cleaner housing. The stepped surface is formed on an upper wall of the air cleaner housing, such that an outer step is arranged on a periphery of an inner step. The upper wall is formed into a stereoscopic shape by providing the stepped surface thereon, such that the rigidity of the upper wall is enhanced, and a sonic resonance of the upper wall can be suppressed during vehicle operation, thereby reducing intake noises. By providing the stepped surface to the upper wall of the air cleaner for reducing intake noises, and it is unnecessary to add one or more extra components to the air cleaner for reducing intake noises.

This treatment device for endoscope is used for cutting body tissue while the treatment device is retractably projected from a catheter. The treatment device includes: a control wire inserted into the catheter; and a cutting electrode mounted at the distal end of the control wire with the cutting electrode being imparted a bent configuration in advance. The cutting electrode elastically deforms in a state where the cutting electrode is retracted into the catheter, thereby assuming such a shape as to resemble the configuration of the catheter.

In a rolling process, the level of rolling performed by a rolling mill for one operation is set to 1 μm to 20 μm. A magnesium substrate is rolled by rollers while being heated by a thermostatic chamber. As a result, there is manufactured a high-quality magnesium sheet which is less susceptible to influence of oxidation, which realizes a high internal loss, prevention of a drop in sensitivity, and low distortion, and which has a thickness of 30 μm to 100 μm. Further, as a result of the magnesium sheet being formed into a semi-dome shape or a dome shape, the sheet can be inexpensively manufactured as a speaker for high-tone playback. In particular, in the case of a magnesium diaphragm into which a dome section and an edge section are integrally formed, high-quality sound can be played back in a high frequency range without involvement of a drop in sensitivity.

In a foam molding method useful in efficiently manufacturing a foam molding with high surface accuracy and a mold suitable therefor, a plurality of gas-blowing devices 24 including the following members are arranged in the bottom of a cavity 23 present in a lower die 22: valve boxes 25, gas channels 26, valve elements 27, gas flow-restricting valves 28, and other members. The gas channels 26 of the gas-blowing devices 24 are supplied with gas from a common air pump. The valve elements 27 move vertically such that openings of the gas channels 26 that arranged in the cavity are opened or closed. When the gas is supplied to the gas channels 26, the valve elements 27 are moved upward by the pressure of the gas so as to push a molding 34. The valves 28 move upward together with the valve elements 27 and then sit on valve seat sections 31 disposed in the gas channels 26 to restrict the gas to flow into the gas channels 26. The valves 28 have vent holes 32; hence, the gas is allowed to flow into the gas channels 26 although the amount of the glowing gas is small.

A refueling operation of an all terrain vehicle can be enhanced, even when a fuel tank is arranged below a seat, without changing an entire length of the vehicle. A fuel tank is arranged below a seat. A seat concave portion with a substantially concave shape when viewed from the top is formed in the seat. A fuel filler of the fuel tank is arranged in the seat concave portion to be seen from the top. It becomes possible to perform refueling from the fuel filler without detaching the seat. Also, an overlap between the seat and the fuel filler when viewed from above is avoided, with a reduction in a seating area of the seat minimized.

An intake and exhaust device for a multi-cylinder engine includes: a first intake and exhaust system corresponding to a first cylinder group and having an exhaust passage and an intake passage; a second intake and exhaust system corresponding to a second cylinder group and having an exhaust passage and an intake passage; a communication passage through which the exhaust passage of the first intake and exhaust system and the exhaust passage of the second intake and exhaust system communicate with each other; an adjusting valve for opening and closing the communication passage; an EGR unit for causing exhaust gas to circulate between the exhaust passage and the intake passage of the first intake and exhaust system and between the exhaust passage and the intake passage of the second intake and exhaust system respectively; and a control unit for controlling opening and closing of the adjusting valve and circulation of exhaust gas by the EGR unit based on an operating condition of the engine.
摘要:
A control unit cooling device for an industrial vehicle that can efficiently cool the control unit, wherein the control unit includes a cooling portion integrally formed with an electric circuit. In one embodiment of the invention, the control unit cooling device may be implemented on an industrial vehicle, such as a counterbalanced forklift. The cooling device has a first air current generation mechanism and a second air current generation mechanism. The first air current generation mechanism generates a first air current from air drawn in from the outside of a vehicle body. The first air current cools the electric circuit. The second air current generation mechanism generates a second air current from air drawn in from the outside of the vehicle body. The second air current cools the cooling portion. This efficiently cools the control unit.
