A conical frustum shaped air cleaner comprised of a porous foam material in multiple layers. A cavity opening is formed at the center section of the flat bottom surface of the cleaner. The airflow resistance through the aforementioned foam material formed in the tapered side section of the cleaner is different from the airflow resistance through the foam material comprising the upper-surface section of the air cleaner. The desired airflow resistance is also controlled by selecting the appropriate number of layers, the appropriate thickness and the appropriate foaming ratio of the applicable foam materials that comprise the side-surface section and upper-surface section of the air cleaner.

The connecting mechanism 10 is stretchable and contractible.
摘要:
A laser groove machining method for forming bottomed grooves in a surface of a workpiece using a laser, wherein an emitting position of a laser beam which is to be emitted onto the workpiece is shifted relatively along groove forming positions at a high speed of 150 mm/min. or faster. Thus, melted portions which are melted by the laser beam can easily be separated, cooled and removed by shifting the laser beam emitting position at high speed. In addition, water may be jetted to the workpiece so as to form a pillar of water so that the laser beam is emitted through the interior of the pillar of water so formed.

A sound increase apparatus includes a partition wall adapted to divide an engine room for defining a first engine room space that is located on a side of a dash panel and a second engine room space in which an engine is installed, and a first pressure fluctuation amplification unit inter-communicating an engine inlet pipe arranged in the second engine room space and the first engine room space. The first pressure fluctuation amplification unit amplifies a pressure fluctuation of a first frequency selected from a plurality of frequencies when pressure of air residing inside the engine inlet pipe fluctuates at the plurality of frequencies.
摘要:
An MCU determines whether a backlash over a predetermined value exists in a driving system including a motor and a window driving mechanism. Then, when it is determined that the backlash over the predetermined value exists in the driving system, the MCU sets the time passed from the detection of the peak of the number of rotations of the motor to a predetermined additional time as a termination time of a start cancellation period. When it is determined that the backlash over the predetermined value does not exist in the driving system, the MCU sets, as the termination time of the start cancellation period, the time when the rate of change of the number of revolutions of the motor reaches a predetermined value or the time when the rate of change of a motor input ratio reaches a predetermined value.

A probe 10 receives an echo signal, and the echo signal is stored in memory 18. Operation desk 28a has at least one readout-range setting device 34 for setting an echo signal readout-sensitivity range of the echo signal stored in memory 18. Echo signals in the sensitivity range preset by readout-range setting device 34 is read out from memory 18 from among the echo signals in the sensitivity range stored in memory 18. The echo signal read out of memory 18 is converted into data corresponding to the display dynamic range of monitor 24a by a digital gain regulation circuit 31. The converted data is inputted into image construction unit 22 to create image data. The image data is displayed on the screen of monitor 24a.
