摘要： An inverter circuit produces a proper electric power to be supplied to a discharge lamp. A feedback control system detects a lamp voltage and a lamp current, or a lamp power of the discharge lamp, and feedback-controls the inverter circuit based on the detected at least one of the lamp voltage, lamp current and lamp power. A response switching circuit switches a response speed of the feedback control system so that the response speed is high in a low luminous efficiency region, and is low in a high luminous efficiency region.

摘要： There are disclosed a process for producing methyl formate by dehydrogenating methanol in liquid phase in the presence of a solid catalyst and a process according thereto wherein a gas (N.sub.2, H.sub.2, CO, etc.) is continuously blown into the liquid phase from outside, and the gas along with the reaction product are continuously withdrawn outside the reaction system from the gaseous phase directly or through a cooler. By virtue of the liquid-phase reaction in the above process, as compared with the conventional gaseous phase reaction, the reaction temperature can be lowered, the reaction gas rich in the objective methyl formate rather than methanol is obtained by continuously withdrawing the resultant methyl formate outside the reaction system and accordingly, a single pass yield higher than that at the thermodynamical equilibrium-value is assured, whereby energy saving is made possible.

摘要： When a communication network system is constructed using an optical fiber as a transmission path, a node which transmits a signal may receive its own transmission signal upon reflection of an optical signal on the transmission path. When access control to a network is performed by a CSMA/CD method, the reflection signal may be erroneously detected as a signal sent from another node, and a collision which has not actually occurred may be detected. In order to avoid this, a reflection signal component of the transmission signal must be removed from a reception signal. For this purpose, a time-inverted signal of the transmission signal, and the reception signal are modulated, and the modulated signals are then input to a convolver, thereby obtaining a convolution integral value between the two signals. Since the transmission signal component included in the reception signal can be detected from the obtained value, the detected transmission signal component is removed from the reception signal component, and a signal transmitted from another node can be extracted. In this manner, erroneous detection of a collision upon reflection of a signal transmitted from its own node can be prevented.

摘要翻译： 当使用光纤作为传输路径构建通信网络系统时，发送信号的节点可以在传输路径上反射光信号时接收其自身的传输信号。 当通过CSMA / CD方法执行对网络的访问控制时，反射信号可能被错误地检测为从另一个节点发送的信号，并且可能检测到没有实际发生的冲突。 为了避免这种情况，必须从接收信号中去除发送信号的反射信号分量。 为此，对发送信号的时间反转信号和接收信号进行调制，然后将调制信号输入到卷积器，从而获得两个信号之间的卷积积分值。 由于可以从获得的值检测包含在接收信号中的发送信号分量，所以从接收信号分量中去除所检测的发送信号分量，并且可以提取从另一个节点发送的信号。 以这种方式，可以防止从其自身节点发送的信号的反射错误地检测碰撞。

摘要： A portable video camera and recording apparatus is comprised of a video camera section and a recording section. The video camera section is comprised of a CCD, analogue-to-digital converters for converting signals from the CCD into digital form. The digital signals are then processed, converted into analogue form, processed in analog form, and then output as the composite video signal. A digital luminance signal and either a digital composite color signal or a plurality of digital color difference signals are received as inputs into the recording section. If the digital composite color signal is received, then the signals are time-base-compressed, converted into analogue form, the composite color signal is frequency converted and filtered and the luminance signal is frequency modulated and filtered. Next, the signals are added together and recorded onto a recording medium. If the digital color difference signals are received, the digital color difference signals are multiplexed together, converted into analogue form, frequency modulated, filtered and then recorded onto one track on the recording medium. The digital luminance signal is time-base-compressed, converted into analogue form, frequency modulated, filtered, and then recorded onto a second track on the recording medium.

摘要： An optical communication terminal detects an unused first wavelength in a wavelength range in response to a transmission request and transmits a call signal to a transmission destination using the first wavelength. An acknowledgement signal from the destination is detected in a portion of the wavelength range not including the first wavelength. When a call signal addressed to the terminal from another terminal is detected thereat and the terminal is ready for communication, an unused second wavelength in the wavelength range is detected and an acknowledgement signal is sent using the second wavelength in response to the call signal.
