摘要:
The objective of the present invention is to efficiently and inexpensively mass-produce a sound insulator for a vehicle which is light in weight and has excellent sound insulating properties. For this purpose, the ultra-light sound insulator of the present invention is composed of a felt single sheet 3 having a vehicle interior side surface 1 and a vehicle exterior side surface 2 and being thermoformed of cotton fibers and binder fibers which are tangled and contacted and jointed to each other in a random manner. The ratio of the stiffness of the vehicle interior side surface 1 to that of the vehicle exterior side surface 2 is set to be in a range of 1.1 to 10. The single sheet 3 also has an area of gradually-decreasing stiffness 4 that spreads over at least one part of the area between the vehicle interior side surface 1 and the vehicle exterior side surface 2. The area of gradually-decreasing stiffness 4 has a stiffness distribution pattern in which the stiffness decreases gradually from the vehicle interior side surface 1 toward the vehicle exterior side surface 2 with respect to the direction perpendicular to the vehicle exterior side surface 2.

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:
Disclosed is a data collector that collects a first data string sent by a control unit to a network according to a predetermined format. The control unit has a first identification number, and the first data string includes the first identification number and a parameter which is used to control a vehicle or a vehicle component. The data collector includes a first collecting means for collecting the first data string sent by the control unit; and a second collecting means for collecting a second data string sent by a data converter. The data converter has a second identification number different from the first identification number of the control unit and the second data string conforms to the predetermined format. The data converter converts analog data sent from a sensor that detects a driving condition of the vehicle into digital data, puts the second identification number and the digital data in the second data string to be sent, and sends the second data string at a predetermined interval.
摘要:
During a downshift of a belt-drive continuously variable transmission, occurring owing to vehicle deceleration, a CVT controller foretells that a slippage between a drive belt and each of primary and secondary variable-width pulleys tends to occur, when a primary pulley pressure is less than a first predetermined pressure level and a primary pulley speed is less than a first predetermined rotational speed. When the belt slippage has been foretold, the CVT controller inhibits the primary pulley pressure from dropping by setting an actual transmission ratio calculated before a set time period from a time when the slippage has been foretold or a transmission ratio of a relatively higher speed side as compared with a ratio-change operating state obtained when the slippage has been foretold, to a desired transmission ratio, or by relatively rising a line pressure as compared with a line pressure level produced when the slippage has been foretold.
摘要:
The shift control apparatus for a continuously-variable transmission includes; a primary pulley; a secondary pulley connected with the primary pulley by a belt; a shift actuator adapted to vary a speed ratio; a line pressure adjusting section configured to adjust a line pressure; a secondary-pressure adjusting section configured to adjust a secondary pressure; and a control section configured to control the shift actuator, the line pressure adjusting section, and the secondary-pressure adjusting section. Moreover, the control section includes a fail determining section configured to determine whether the shift actuator is under a failed condition. The control section is configured to carry out a fail-safe shift-actuator fixing control to fix the shift actuator, when the fail determining section determines that the shift actuator is under the failed condition, and is configured to carry out a fail-safe hydraulic control to bring the line pressure to its upper limit pressure and bring the secondary pressure to its maximum pressure, when a control-start criterion predetermined to secure driving performance of the vehicle is satisfied under the failed condition.
摘要:
A plurality of TEM mode transmission lines (L2-L5) are structured by pairs of thin film conductors (21 and 22, 22 and 23, 23 and 24, and 24 and 25) which sandwich thin film dielectrics (31 to 34) by alternately stacking the thin film conductor (21 to 25) and the thin film dielectric (31 to 34). The phase velocities of TEM mode waves which are propagated at least by two of the transmission lines (L2 to L5) are substantially equal to each other. The thickness of each of the thin film conductors (21 to 25) is smaller than the skin depth of the frequency used so that the electromagnetic fields of at least two TEM mode transmission lines among the TEM mode transmission lines (L2 to L5) are coupled to each other. In this way, the skin depth can be increased effectively. The conductor loss and the surface resistance can be reduced significantly as compared to those of the conventional electrode. By use of this electrode, a transmission line, a resonator, a filter, and a high frequency device are structured.
摘要:
A high-frequency integrated circuit which operates in a microwave band or in a millimeter wave band. The high-frequency integrated circuit has a plurality of devices with respective nonradiative dielectric waveguides such as an oscillator, a coupler, etc., and a substrate on which these devices are surface-mounted. Each of the devices has a pair of parallel conductors, a dielectric strip which is disposed between the conductors and propagates a high-frequency electromagnetic wave, a mounting surface which is formed on one of the conductors and is in contact with the substrate, and an end surface which is defined by an end of the conductors so as to be vertical to a traveling direction of the electromagnetic wave propagated in the dielectric strip and at which an end of the dielectric strip is exposed. The devices with a nonradiative dielectric waveguide are evaluated separately, and thereafter, the devices are surface-mounted on the substrate close to or in contact with one another.
