摘要： Dust containing high-temperature gas exhausted from an electric steelmaking furnace is directed through scrap preheaters, wherein scrap that is to be charged into said electric furnace is preheated. The absorption of some of the heat from the exhaust leaving the electric furnace by the scrap, therefore, decreases the amount of electric power required for melting the steel scrap and also shortens the time required for steelmaking. Exhaust gas after preheating of the scrap is contaminated with incidental malodorous materials, e.g., paint and oil fumes, and is directed through a gas scrubber followed by a wet-type electric precipitator to remove these contaminants before release of cleaned exhaust gas into the atmosphere. A flow of alkaline aqueous solution of a deodorant solvent in the gas scrubber removes malodorous substances from the exhaust gas, simultaneously causing a drop in the gas temperature to a predetermined controlled value while generating a constant supply of saturated water vapor. Exhaust gas mixed with the saturated water vapor then flows through a wet-type electrostatic precipitator which collects oil mist attached to the water vapor and any small water droplets entrained therein. This purging of dust and malodorous constituents from the exhaust gas facilitates preheating of scrap for electric steelmaking processes, providing benefits of improved economy and reduced environmental air pollution.

摘要翻译： 含有从电炼钢炉排出的高温气体的粉尘被引导通过废料预热器，其中将要加入到所述电炉中的废料被预热。 因此，通过废料从排出电炉的排气中吸收一些热量，减少了熔炼钢渣所需的电力量，并缩短了炼钢所需的时间。 废料预热后的废气被偶然的恶臭物质（例如油漆和油烟雾）污染，并且被引导通过气体洗涤器，随后是湿式电除尘器以除去这些污染物，然后将净化的废气释放到大气中。 气体洗涤器中除臭溶剂的碱性水溶液流从废气中除去恶臭物质，同时使气体温度下降到预定的受控值，同时产生恒定的饱和水蒸气。 与饱和水蒸气混合的废气然后流过湿式静电除尘器，其收集附着在水蒸汽上的油雾和夹在其中的任何小水滴。 从排气中清除灰尘和恶臭成分有助于预热电炼炼工艺废料，提供经济改善和减少环境空气污染的好处。

摘要： A mounting member has a tube, and a plurality of clamps. The clamps hold the tube or outer portions on both sides of the tube. Therefore, the external load on the mounted part can be minimized while at the same time the mounted part is easily held fixedly on a board such as a printed wiring board.

摘要： First to fourth initial data memories 31a to 31d prestore initial data R obtained when a reference optical fiber 22 having a predetermined length was previously measured, and initial data Pa to Pc obtained when a to-be-monitored optical fiber was previously measured. A first arithmetic unit 33 finds a difference .alpha. between measurement data R' obtained when the reference optical fiber 22 is newly measured and the initial data R as a first drift amount representing a variation in characteristics of the OTDR itself. A second arithmetic unit 34 finds a difference .beta. between measurement data P' obtained when the to-be-monitored optical fiber 1 is newly measured and the initial data of the to-be-monitored optical fiber as a second drift amount representing a variation in characteristics of the OTDR itself and characteristics of the to-be-monitored optical fiber 1. A third arithmetic unit 35 finds, from a difference between .beta. and .alpha., a real characteristic variation amount .gamma. of the to-be-monitored optical fiber 1 as a third drift amount representing a variation in characteristics of the to-be-monitored optical fiber 1. A waveform comparator 36 detects the presence/absence of abnormality of the to-be-monitored optical fiber 1 based on the real characteristic variation amount .gamma. of the to-be-monitored optical fiber 1.

摘要： In a three-dimensional YC separating circuit including an intra-field YC separating circuit and an inter-frame YC separating circuit, when an NTSC composite video signal is nonstandard and is used for a static image part of an image, a low pass filtering is performed upon a C signal of the inter-frame YC separating circuit, and the low pass filtered C signal is added to a C signal of the intra-field YC separating circuit. Then, a Y signal is obtained by subtracting the combination of the two C signals from the NTSC composite video signal.

摘要： Two field memories for supplying a composite video signal of a previous frame to a motion detector are provided in performing a three dimensional Y/C separation. An output of the field memory connected to an input terminal is connected to a two dimensional Y/C separator by a switching circuit when there is a request for a function employing a field memory. When there is no such request, the input terminal is connected to the two dimensional Y/C separator. When there is a request for a still reproducing function employing a field memory, the function is realized by using the field memory employed in a three dimensional Y/C separation.

摘要： An automatic phase controlling circuit according to the present invention has a phase shifter and an auxiliary detector for producing a sensitizing signal in association with a signal loop constituted by a main detector for producing a control signal and a voltage-controlled oscillator for producing a variable-phase signal, and the sensitizing signal is delayed in phase from the control signal by about 90 degrees by virtue of the phase shifter, so that the main detector achieves a stability around a phase difference of 0 degree without sacrifice of quick response characteristics at a large difference in phase between the variable-phase signal and a reference signal.
