摘要： An adaptive transform coding/and decoding arrangement is provided to effectively exploit different redundancies between the bands of a spectrum envelope to effect coding at a low bit rate for an audio signal. In the adaptive transform coding method, the spectrum envelope is divided into bands so that different coding methods may be applied to the spectrum envelopes of the individual bands. By applying the present invention to the adaptive transform coding of an audio signal, the spectrum envelope can be adjusted to the coding/and transmission method which is suitable for the time fluctuation in each frequency band, so that the different redundancies for the individual bands can be effectively exploited to realize a highly efficient audio signal coding/and decoding method which has its bits reduced as required for coding the spectrum envelope.

摘要： A communicating pipe for introducing atmospheric pressure to an air vent circuit changeover valve has an intermediate portion provided in a fuel tank and slanted portions extending obliquely upward. The intermediate portion has a drain pipe wherein a drain hole is provided. Liquefied fuel in the communicating pipe is gathered to the intermediate portion through the slanted portions and drained from the drain pipe into the fuel tank. Thus constituted communicating pipe prevents a clogging of liquefied fuel in the communicating pipe.
摘要翻译：用于将大气压引入排气回路切换阀的连通管具有设置在燃料箱中的中间部分和倾斜向上延伸的倾斜部。中间部分具有排水管，其中设有排水孔。连通管中的液化燃料通过倾斜部分聚集到中间部分，并从排水管排出到燃料箱中。这样构成的连通管防止了连通管中液化燃料的堵塞。

摘要： A pressure reducing valve with a breathing hole is incorporated in a dome provided on the upper wall of a fuel tank and it is open to a vent pipe. A fuel cut valve with a leak hole is provided proximately to the pressure reducing valve. Opening-closing means are also provided on the port side of the fuel cut valve so as to actuate both the pressure reducing valve and the fuel cut valve. When an engine is running, the pressure of return fuel is applied to a float of the opening-closing means, whereby the pressure reducing valve is opened and the fuel cut valve is closed. When the engine is stationary, due to no pressure of return fuel, the float goes down to close the pressure reducing valve and open the fuel cut valve.
摘要翻译：具有呼吸孔的减压阀装在设置在燃料箱上壁上的圆顶中，并且通向排气管。具有泄漏孔的燃料切断阀靠近减压阀设置。开闭装置也设置在燃料切断阀的端口侧，以便致动减压阀和燃料切断阀两者。当发动机运行时，返回燃料的压力被施加到打开 - 关闭装置的浮子，由此减压阀打开并且燃料切断阀关闭。当发动机静止时，由于没有返回燃料的压力，浮子下降以关闭减压阀并打开燃油切断阀。

摘要： In an air breather system for the fuel tank of a vehicle, a mechanical seal is provided at the mouth of a filler pipe for preventing overflow from the mouth when filler gun is inserted into the mouth for fueling. The mouth is communicated with a canister for adsorbing the vapor of the fuel through an air breather passage. Even when negative pressure occurs under the mouth, normal fueling is performed without functioning the automatic stop of the filler gun.

摘要： A bypass pipe 10 which bypasses the first and second check valves 13a, 13b of an air breather pipe 8 for the communication between the upper space of a fuel tank 3 and an absorbent 2 contained in a canister 1 is disposed including a first change-over valve 12a which is opened only during the operation of a motor vehicle, while that second vent pipe 16 of the canister 1 which is openable to the atmosphere is furnished with a second change-over valve 12b which enlarges a ventilating cross-sectional area only during the operation of the vehicle. During the running of the vehicle, accordingly, the second vent pipe 16 is opened, and the first and second check valves 13a, 13b interposed in the air breather pipe 8 are invalidated to bring the fuel tank 3 and the canister 1 into direct communication.
