    摘要: 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.

    摘要: In a brake control system for yaw control in a vehicle, the conditions for starting a brake operation are that the absolute value of a deviation between a target yaw rate determined in a target yaw rate determining device and an actual yaw rate detected by a yaw rate detecting device is equal to or greater than a preset deviation value and that the absolute yaw rate is equal to or greater than a preset value. The wheel brake for an outer wheel, during turning of the vehicle, is operated by the yaw control system based on the deviation between both the yaw rates. However, brake control does not occur when both of the yaw rates are the same in direction and are large. Thus, yaw control is conducted immediately when necessary, but the conduction of unnecessary yaw control is avoided, thereby reducing the frequency of the brake operation.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: An apparatus for cleaning an endless photosensitive surface includes a photoreceptor rotatable around a horizontal axis in an electrophotographic copying machine. A cleaning roller and an edge of a blade are maintained in frictional engagement with the upper run of the rotating surface and into the space between the roller and the blade, a cleaning liquid is continuously supplied onto the surface between the blade edge and the cleaning roller, thereby achieving an effective cleaning function. The liquid within the space tending to flow over the other edge of the blade remote from the photosensitive surface and to then drip on the cleaned surface, is effectively prevented in accordance with the invention.

    摘要: A roller is disposed parallel and adjacent to a photoconductive drum with a small gap inbetween. The roller is made of an electrically conductive material and covered with an insulating coating of hard anodized aluminum. The roller is fixed to a shaft which is driven to rotate the roller in the same direction as the drum to remove excess developing liquid from the drum through viscous friction. Electrically conductive bearings are mounted on the ends of the shaft which have an outer diameter greater than the diameter of the roller. The bearings rotatably contact the surface of the drum to maintain the gap. Either insulating plastic bushings or layers of alumite are disposed between the ends of the shaft and the bearings to insulate the shaft from the bearings and thereby from the drum.
