摘要:
A sound insulator of the invention includes a sound absorption layer 202 and an air-impermeable resonance layer 203, which are bonded to each other via an adhesive layer 204. The sound absorption layer 202 has a thickness in a range of 5 to 50 mm and an area-weight of not greater than 2000 g/m2. The sound absorption layer 202 has a two-layer structure of a high-density sound absorption layer 202a and a low-density sound absorption layer 202b, which have different densities. The high-density sound absorption layer 202a is bonded to the air-impermeable resonance layer 203 via the adhesive layer 204 and has a density in a range of 0.05 to 0.20 g/cm3 and a thickness in a range of 2 to 30 mm. The low-density sound absorption layer 202b is bonded to the other face of the high-density sound absorption layer 202a, which is opposite to the air-impermeable resonance layer 203, via an adhesive layer 202c and has a density in a range of 0.01 to 0.10 g/cm3 and a thickness in a range of 2 to 30 mm. The structure of this sound insulator effectively reduces a noise level in a voice-tone frequency band, especially in a high frequency domain, thereby efficiently enhancing the clarity of conversion in a vehicle interior.

摘要:
An order-reception system has: an order-reception subsystem which receives, from a customer, customer order information including order-reception information and/or support request information and customer information; a business management subsystem having a customer-information database storing the customer information including information regarding a price of a commodity purchased frequently by the customer, and a cost of a support requested frequently by the customer, the price and the cost set by a seller; an order-entry subsystem which performs an order-reception processing based on the customer order information; and a delivery subsystem which arranges delivery of the commodity and providing of the support.
摘要:
A continous mixing apparatus has an upper rotary disk and a lower rotary disk able to rotate independently of one another. A plurality of scrapers are attached to the upper and lower sides of the upper and lower rotary disks. Scrapers on the lower side of the lower rotary disk have a notch enabling the scrapers to pass over a lower ring plate in the mixer. Material to be mixed is supplied to an upper portion of the mixer, and the product is discharged from a lower portion of the mixer. The device is constructed to enable any subsequently replenished liquids to not rise to the top of the mixing apparatus. The device produces a mixture that is uniform, highly stable, and that has a small particle size or a low viscosity which can be manufactured quickly.

A highly productive, continuous method for the production of room-temperature-curable organopolysiloxane compositions is obtained by continuously feeding 100 parts by weight of a diorganopolysiloxane with a viscosity at 25.degree. C. of 0.1 to 500 Pa.s that contains at least 2 silicon-bonded hydroxyl groups or hydrolyzable groups in each molecule; 1 to 30 parts by weight of an organosilane that contains at least 2 silicon-bonded hydrolyzable groups in each molecule, or the partial hydrolysis condensate thereof; 1 to 200 parts by weight of an inorganic filler in powder form, and 0 to 10 parts by weight of a cure-accelerating catalyst into a continuous mixing apparatus having starting material feed openings installed at its top, a discharge opening installed at its bottom, and a rotating disk installed within a casing and are therein mixed by the rotation of the said rotating disk, and in that the resulting mixture is thereafter continuously introduced into a vacuum mechanism- equipped degassing apparatus in which the water fraction present in the said mixture is removed under reduced pressure.
摘要:
A fuel supply system has an in-tank module. The in-tank module is provided with a pump, a filter, a pressure regulator and a pressure sensor detecting a fuel pressure. The pressure sensor is disposed on or at a vicinity of the fuel pump so that the pressure sensor easily detects a pulsation component due to the pump. A fuel pump controller includes a speed detection module which detects the rotation speed of the fuel pump based on a cycle of the pulsation component of the pressure detected by the pressure sensor. Thus, the rotation speed of the fuel pump can be indirectly detected by means of the pressure sensor.

The upper and lower sides and the ribs define a plurality of cells which are arranged adjacent one another. Each of the cells has an opening at a front end thereof for introducing air into the canopy. The mesh cloth of the ribs includes large and small apertures disposed therein. According to one embodiment, either the large or the small apertures are arranged in matrix-like groups which are separated from one another by the other of the large and small apertures. According to another embodiment, the large and small apertures are disposed in groups which are arranged parallel to one another in the vertical direction.
