Abstract: Abstract of the Disclosure The specification discloses a reference voltage generator device which detects a voltage corresponding to an energy gap of a semiconductor, or a voltage of a value close thereto, or a voltage based on an energy level of a semi-conductor, and generates the detected voltage as a reference voltage.  The reference voltage is generated by detecting the difference of threshold voltages of first and second insulated gate field-effect transistors (IGFETs).  Gate electrodes of the first and second IGFETs are formed on gate insulating films which are formed on different surface areas of an identical semiconductor substrate under substantially the same conditions.  The gate electrodes of the first and second IGFETs are respec-tively made of two semiconductors which are selected from among a semiconductor of a first conductivity type, a semiconductor of a second conductivity type and an intrinsic semiconductor made of an identical semi-conductor material, and which have Fermi energy levels of values different from each other. The channels of the first and second IGFETs have an identical conductivity type.  On the basis of a self-alignment structure, at least those parts of first and second polycrystalline semiconductor regions being the gate electrodes of the first and second IGFETs which are proximiate to source and drain regions  are doped with the same impurity as that of the source and drain regions, and a central part of one of the first and second polycrystalline semiconductor regions is doped with an impurity of a selected one of the first conductivity type and the second conductivity type. The reference voltage is applicable to a differential amplifier circuit and operational amplifier of the offset type, a voltage comparator, d constant-current circuit, a voltage regulator, a Schmitt trigger circuit, an oscillation circuit, a battery checker, and so on.  In particular, the reference voltage generator device is relatively insensitive to changes of temperature.

Abstract: Abstract of the Disclosure A luminance/chrominance separating apparatus is described in which a luminance and a chrominance signal are extracted from a composite color television signal by a comb filter.  The filter comprises a first delay circuit and a second delay circuit, connected in series, and each delaying the composite color signal by one horizontal scanning period.  First and second delayed signals are thereby obtained.  The second delayed signal is added to the non-delayed television signal to produce a first added signal and this is then added to the first delayed signal to produce a second added signal.  The first added signal is also subtracted from the first delayed signal to produce a subtracted signal and a low frequency signal component is extracted from the subtracted signal.  A variable attenuator attenuates the low frequency signal component and the output of the attenuator is added to the second added signal.

Abstract: ABSTRACT     Metal substrates are protected against corrosion by applying a protective covering of a heat-recoverable article such as a heat-shrinkable sleeve or wrap-around sleeve which is provided with an inner coating or lining of a sealant composition containing a corrosion-inhibitor appropriate to the metal.  The preferred corrosion-inhibitors are soluble so that they dissolve in any moisture which diffuses through the sealant layer and preferably act by passivating the metal surface by anodic or cathodic inhibiticjn mechanisms. The presence of the heat-recoverable material ensures that the soluble corrosion-inhibitors do not become leached out from the sealant composition.
