    • The internal combustion engine control technique of the invention computes a TDC pass rotation speed Ntdc, which represents the rotation speed of an engine when one of multiple cylinders of the engine passes over a top dead center TDC (step S110). The control technique estimates an engine stop crank angle CAs from a map that is experimentally or otherwise obtained to represent a variation in TDC pass rotation speed Ntdc against the stop position of the engine (step S120), and specifies a fuel injection cylinder that stops in a preset cycle range including part of a compression stroke at a stop of the engine (step S130). The specified fuel injection cylinder receives lean fuel injection at a specific fuel injection timing (step S170). When the specified fuel injection cylinder is later presumed not to pass over a top dead center TDC of the compression stroke, a corrected amount of fuel is injected into the specified fuel injection cylinder (step S240). When the specified fuel injection cylinder is later presumed to pass over the top dead center TDC of the compression stroke, on the other hand, the control technique ignites an air-fuel mixture of the intake air and the injected fuel for combustion in the compression stroke, synchronously with fuel injection into a next cylinder that goes into the compression stroke after the specified fuel injection cylinder (step S270).
    • 本发明的内燃机控制技术计算出TDC通过转速Ntdc,其表示当发动机的多个气缸中的一个通过上止点TDC时的发动机的转速(步骤S110)。 控制技术根据实验或以其他方式获得的映射表示发动机停止曲柄角CAs,以表示相对于发动机的停止位置的TDC通过转速Ntdc的变化(步骤S120),并指定停止的燃料喷射缸 在包括在发动机停止时的压缩冲程的一部分的预设循环范围内(步骤S130)。 指定的燃料喷射缸在特定的燃料喷射正时接收贫燃料喷射(步骤S170)。 当指定的燃料喷射缸后来被推定为不超过压缩冲程的上止点TDC时,将校正量的燃料喷射到指定的燃料喷射缸中(步骤S 240)。 另一方面,当指定的燃料喷射缸被推定为经过压缩冲程的上止点TDC时,另一方面,控制技术在压缩冲程中点燃进气和喷射燃料的燃料混合物,用于燃烧 与在特定燃料喷射缸之后进入压缩冲程的下一个气缸中的燃料喷射同步(步骤S 270)。

    • An object of the invention is to provide a receiving circuit where the quality of reception can be prevented from deteriorating when the gain changes, so that the good quality of the received signal can be preserved, as well as a receiving apparatus and a transmitting/receiving apparatus using the receiving circuit. In the configuration of the invention, a switch (113) is converted to a short state in response to a change in the gain of a variable gain amplifier (107) by means of a gain control apparatus 112, and thereby, the output terminal of a high pass filter (111) is fixed at a reference voltage and the cutoff frequency of a low pass filter (108) is increased. As a result, the period during which the DC voltage has transient response properties in the low pass filter (108) can be shortened, and this transient response prevented from passing through the high pass filter (111).
    • 本发明的目的是提供一种接收电路,其中当增益改变时可以防止接收质量恶化,从而可以保持接收信号的良好质量,以及接收装置和发送/接收 使用接收电路的装置。 在本发明的结构中,通过增益控制装置112响应于可变增益放大器(107)的增益的变化而将开关(113)转换为短状态,由此,输出端子 高通滤波器(111)被固定在参考电压上,并且低通滤波器(108)的截止频率增加。 结果,可以缩短在低通滤波器(108)中具有瞬态响应特性的直流电压的周期,并且防止该瞬态响应通过高通滤波器(111)。
