An object of the present invention is to bring a video signal obtained by imaging into a proper level without use of a controllable diaphragm. An imaging apparatus is provided with no controllable diaphragm. Peak detection is performed by a peak detecting circuit for each vertical scanning interval. A peak value is applied to a control device. Necessary shutter speed control in a shutter control circuit, gain control in a pre-amplifier circuit and gain control in a GCA are carried out. Consequently, the level of the video signal obtained by the imaging is adjusted to a proper level without controlling a diaphragm, to obtain an image of proper brightness.

摘要:
The present invention relates to a composite tubular article for use as the fixing belt in an image-forming device such as a copying machine etc., particularly as a fixing belt suited for thermal fixing, and also relates to a process for producing the same.Conventionally known as an image-fixing belt is a belt consisting of a polyimide resin as the inner layer and a fluoroplastic as the outer layer. However, this fixing belt has problems that clear images cannot be obtained because the thickness of each layer is uneven, and that unglossed, so-called matt images cannot be obtained because the belt surface is smooth.This invention provides a composite tubular article comprising a tubular inner layer made of a polyimide resin and a tubular outer layer made of a fluoroplastic, the outer circumferential surface of the fluoroplastic tubular outer layer having a surface roughness of 1 to 10 .mu.m. The invention further provides, as a production process for the same, a process in which the outer layer is formed by use of a cylinder having an inner circumferential surface with a surface roughness of 1 to 10 .mu.m, and a polyimide-resin tubular inner layer is formed on the inner circumferential surface of the outer layer by converting a poly(amic acid) into a polyimide, or a process in which an inner layer formed by converting a poly(amic acid) into a polyimide is immersed in or sprayed with a fluoroplastic solution in which a particulate material of 5 .mu.m or smaller has been dispersed, thereby to form an outer layer.

A quartz glass crucible for pulling a single crystal, which comprises a cylindrical straight portion, a bottom portion and a curved intermediate portion for connecting the straight portion and the bottom portion. The straight portion has an opaque area positioned within about 75% or less of the total height of the crucible, measured from the upper open end of the crucible. The opaque area in the straight portion has a total bubble volume which ranges from about 7.times.10.sup.-3 cm.sup.3 /cm.sup.3 to 30.times.10.sup.-3 cm.sup.3 /cm.sup.3. The remaining straight portion, the curved intermediate portion and the bottom portion consist of two layers. One layer is an inner transparent layer having a total volume of bubbles of about 4.times.10.sup.-3 cm.sup.3 /cm.sup.3 or less and corresponds to from about 20% to 60% of the thickness of the crucible, measured from the inside surface thereof. The other layer is an outer opaque layer having a total volume of bubbles ranging between about 7.times.10.sup.-3 cm.sup.3 /cm.sup.3 and 30.times.10.sup.-3 cm.sup.3 /cm.sup.3, which is integral with the opaque area of the upper part of the straight portion.

摘要:
A digital radio transmission system having a first terminal office (10), a second terminal office (20) and at least one drop/insertion (DI) office (30) located therebetween. Long distance lines between the first and second terminal offices are handled in the DI office together with first and short distance lines each being replaced by first and second protection lines, respectively. A protection line for the long distance lines is realized by commonly using the first and second protection lines inherently allotted to the first and second short distance lines. Further the line switching, due to a fault in the long distance line, from the faulty long distance line to the both the first and second short line side protection lines can be achieved by communicating a particular line switching control signal among all the offices.
