Title: Signal level adjusting circuit
Inventor: YAMAGUCHI TSUGIO
IPC: H04N9/83
Filed: 1991-03-31
Abstract: PURPOSE:To perform the signal level adjustment by giving the external reference current having no temperature dependency to the output step of a voltage-current conversion circuit composed of 2 steps of differential amplifiers, converting it into an alternating current of the product with the input signal and adding it to a second external reference current of direct current. CONSTITUTION:In a video signal Vin inputted from an emphasis circuit 11, the voltage change is converted into the change of an alternating current (i) via a prescribed gilbert amplifier 12 composed of 2 steps of differential amplifiers 14, 15. The alternating current i is obtained by the product of a constant K having no temperature characteristic by being contracicted in a first differential amplifier circuit 14, an external reference current IX1 having no temperature characteristic to be supplied to a second differential amplifier circuit 15 and an input signal Vin. As the gain of the alternating current (i) is that it can be controlled by an external reference current IX1 and it has no temperature dependency, the signal level can be easily adjusted by controlling an external control signal IX1. The carrier and deviation are automatically adjusted by adding the control signal of direct current from pins 10A, 10B, respectively, converting and gaining, respectively and adding to a carrier direct current IX2.

Title: Manufacture of leading-in wire for electron tube
Inventor: KONISHI KENICHI
IPC: H01J9/28
Filed: 1980-07-07
Abstract: PURPOSE:To prevent any contact between leading-in wires for an electron tube which might be caused during the formation of oxidized films, by dividing the oxidation treatment of the leading-in wires into the first and the second steps, and providing the stage of stirring between the above two treatment steps. CONSTITUTION:Numbers of pinlike alloy wires (each consisting of Fe, 42% of Ni and 6% or Cr) which have a diameter of 1mm. and a length of around 25mm. and are subjected to polishing and defatting washing, are put in an oxidation treatment boat, and are subjected to high-temperature treatment carried out at 1,100 deg.C in a wet atmosphere of hydrogen for 10min to make the pinlike alloy wires to be coated with oxidized films. After the above oxidation treatment is stopped, the alloy wires contained in the boat are thoroughly stirred before they are subjected to the second high-temperature treatment, which is carried out at 1,100 deg.C in a wet atmosphere of hydrogen for 140min, to make the pinlike alloy wires to be coated with other oxidized films. Thus prepared alloy wires coated with double oxidized films are used as leading-in wires for an electron tube. By the means mentioned above, the alloy wires don't touch any other alloy wire during the development of the oxidized films. Consequently, leading-in wires without any damage to their films can be obtained.

Abstract: PURPOSE:To obtain the sharp image of an embedded pipe, by scanning a transmitting and receiving antennae, which are provided in the direction crossing the axis of the embedded pipe at right angles, toward the direction crossing said axis at right angles. CONSTITUTION:Transmitting and receiving antennae are arranged in the direction (x) traversing a road at the certain point y1 on the embedded pipe 6 embedded along the road direction (y), that is, in the direction crossing the axis of the embedded pipe 6 at right angles. Then, a short pulse radio wave is emitted into the ground and both or one of the transmitting and receiving antennae are scanned in the direction (x) to obtain the cross-sectional image 10-1 in the direction crossing the axis at right angles. Next, both antennae are scanned in the axial direction and cross-sectional images 10-2, 10-3, 10-4 are also respectively obtained at points y2, y3, y4 slightly separated in the axial direction of the embedded pipe 6 by the same way. When thus obtained four cross-sectional images are super-imposed one upon another, because all cross-sectional images are present at the almost same position, the image of the embedded pipe 6 is intensified in its density at the part thereof. However, because the image of foreign matters such as stones in the ground hardly appears at the same position, the possibility of mutual intensification in densities, if any, is reduced. Therefore, only the image of the embedded pipe 6 is obtained sharply.
