    • The method of manufacturing an epoxide according to the present invention includes: a dehydrogenation step 1, in which a gas A containing an alkane is dehydrogenated, producing a gas B which contains an alkene and hydrogen; an epoxidation step 2, in which the gas B is epoxidized by use of a gas C containing oxygen in the presence of a catalyst containing gold, producing a gas D which contains an epoxide and unreacted hydrogen and oxygen; a separation step 3, in which the epoxide is separated from the gas D, leaving a gas E; and an oxygen elimination step 4, in which oxygen and hydrogen contained in the gas E are allowed to react, eliminating the oxygen and leaving a gas F. At least part of the gas F (gas F.sub.1) is recycled by returning it to the dehydrogenation step 1. Hydrogen produced in the dehydrogenation step 1 is consumed in the epoxidation step 2 and the oxygen elimination step 4, and thus does not build up in the system of reaction. Accordingly, it is not necessary to separate or eliminate the hydrogen from the system of reaction. In other words, a method can be provided which is industrially advantageous for continuously producing an epoxide from an alkane.
    • 根据本发明的环氧化物的制造方法包括:脱氢步骤1,其中含有烷烃的气体A脱氢,产生含有烯烃和氢气的气体B; 环氧化步骤2,其中气体B在含有催化剂的存在下使用含氧的气体C进行环氧化,产生含有环氧化物和未反应的氢和氧的气体D; 分离步骤3,其中环氧化物与气体D分离,留下气体E; 和氧气消除步骤4,其中使气体E中所含的氧气和氢气发生反应,消除氧气并留下气体F.至少部分气体F(气体F1)通过将其返回脱氢而再循环 在脱氢步骤1中产生的氢在环氧化步骤2和氧消除步骤4中消耗,因此不会在反应体系中积聚。 因此,不需要从反应体系中分离或除去氢。 换句话说,可以提供一种工业上有利于从烷烃连续生产环氧化物的方法。

    • A fuel injection apparatus for internal combustion engine of this invention applies detection output of a wide-range air/fuel ratio sensor to an observer so as to estimate an air/fuel ratio of individual cylinder and, based on thus estimated air/fuel ratio, obtains an air/fuel ratio correction coefficient for individual cylinder and correctively controls the fuel injection amount for individual cylinder with the air/fuel ratio correction coefficient for individual cylinder. While the estimation processing of the observer is always continued, the air/fuel ratio correction coefficient for individual cylinder is automatically adjusted, for example, when the estimated air/fuel ratio becomes an abnormal value, according to operational condition of the internal combustion engine, and the like, thereby securing the stability in the corrective control and preventing the emission from deteriorating. Also, the calculation processing of the air/fuel ratio correction coefficient for individual cylinder is thinned out at a predetermined timing in response to increase in the engine speed, for example, to shorten the corrective control, thereby achieving the purification of the exhaust gas even when the internal combustion engine is at a high speed.
    • 本发明的内燃机的燃料喷射装置将大范围的空气/燃料比传感器的检测输出应用于观测者,以估计各个气缸的空燃比,并且基于这样估计的空气/燃料比, 获得单个气缸的空燃比校正系数,并且对各个气缸的空燃比校正系数进行各个气缸的燃料喷射量的校正。 在观察者的估计处理总是持续的情况下,根据内燃机的运转状态,例如当估计的空气/燃料比成为异常值时,自动调节各气缸的空燃比校正系数, 从而确保了校正控制中的稳定性并防止了排放的恶化。 此外,响应于发动机转速的增加,单个气缸的空燃比校正系数的计算处理在预定定时被稀疏,例如缩短校正控制,从而实现排气的均匀化,甚至 当内燃机处于高速时。

    • A first pictorial communication apparatus for transmitting and receiving a pictorial signal and a sound signal through a first channel and a control message through a second channel, having a line interface for communicating with ISDN, a video codec portion for coding and decoding of the pictorial signal, a key input portion and a camera, further comprises a character storing portion for storing character codes in corporation with the key input portion, a data conversion portion for converting character data train read from the character storing portion into a character video signal. On arrival of a call in an automatic answering mode, the character data train is read and transmitted through the first channel in place of a video signal from the camera after the conversion. The second apparatus has similar structure. A called second apparatus transmits the character code data train included in the control message through the second channel in the automatic answering mode on the arrival of call without the conversion. The called apparatus detects the character code data train from the control message and indicates the character code data train as an answering message after conversion by the data conversion portion.

    • A hybrid circuit composed of semiconductor current amplifiers without an inductance and large capacitance has been found. The DC speech current supplied by the DC power source (33) and the speech signal from the modem (28) are adjusted by the current amplifiers (17a, 17b) so that the subscriber line (2) is terminated with the predetermined impedance (600 ohms), and the speech signal from the subscriber line (2) is transferred to the modem (28) through the AC monitor circuits (24a, 24b). The common mode noise induced on the subscriber line (2) is cancelled by adjusting the input current of said current amplifiers (17a, 17b) by the common mode noise detector (22) and the common mode noise monitor circuits (23a, 23b). The speech signal from the modem (28) to the subscriber line (2) does not return to the modem (28) because of the cancellation operation by the return signal detector circuit (32). The present hybrid circuit is suitable to compose a semiconductor integrated circuit (IC) because no inductance is used and no large capacitor is used.
