A radiation resistant composition includes 100 parts by weight of a polymer, 5 to 80 parts by weight of an aromatic series process oil that a polycyclic aromatic (PCA) extract by an IP 346 method (DMSO extraction) is not more than 3% and an aromatic compound content is not less than 20% by a Kurtz analysis, and a radiation resistance imparting agent. The polymer is cross-linked or vulcanized. A wire or a cable includes an insulation and/or a sheath material including the radiation resistant composition.

A radiation-proof resin composition includes a polymer containing chlorine, a radiation resistance providing agent for providing the polymer with a radiation resistance, an amorphous inorganic material for capturing an ionic component generated in the polymer by radiation application, and a reinforcing material for reinforcing a mechanical strength of the polymer. An amount of the reinforcing material is not more than that of the amorphous inorganic material.

A voltage-controlled oscillator includes a resonator section in which a plurality of types of variable capacitance elements having different structures and capacitance variation characteristics are connected in parallel and capacitance values of the plurality of types of variable capacitance elements are controlled simultaneously by a control voltage; and an amplifier section for maintaining oscillation produced by the resonator section. Varactor diodes and MOS varactors can be used as the variable capacitance elements.

Disclosed is an image display apparatus including a recording unit in which a plurality of images are recorded, an obtaining unit which obtains at least one displaying image from the recording unit, a display unit and a setting unit which sets at least one image display region in the display unit. The image display apparatus further includes a deciding unit which decides a position for arranging the displaying image in the image display region and a control unit which displays the relating information corresponding to the displaying image in a non-arranging region along a longer dimensional direction thereof.

Disclosed is a method for estimating, within a short time, the life of a cable insulating coating material containing an antioxidant in a suitable concentration based on the rate of decrease of the antioxidant and on the critical concentration of the antioxidant at which oxidative degradation rapidly proceeds. The method tests the coating material to examine its life, the coating material including a base polymer, and an antioxidant having a functional group suppressing an oxidative deteriorative reaction of the base polymer. The method includes performing a thermal degradation test on the coating material; determining the degradation levels and degradation rates of the coating material at two or more time points in the thermal degradation test, based on the ratio of the absorbance of the functional group of the antioxidant to the absorbance of the base polymer; and thereby evaluating the life of the coating material.

A photosensor system includes a photosensor array constituted by two dimensionally arraying a plurality of photosensors, an image reading section which reads a subject image at a predetermined image reading sensitivity by using the photosensor array, a sensitivity adjustment image reading section which reads a sensitivity adjustment subject image while the image reading sensitivity in the photosensor array is changed to a plurality of stages, an optimal image reading sensitivity deriving section which derives an image reading sensitivity optimal for reading operation of the subject image, on the basis of a pixel data group relating to an image pattern of the subject image read by the sensitivity adjustment image reading section, and an image reading sensitivity setting section which sets the optimal image reading sensitivity as the image reading sensitivity in the image reading section.
摘要:
A downconverter capable of being normally operated even in the case where a universal dual downconverter is made up by use of multiple downconverter circuits. The downconverter includes first and second downconverter circuits, and an amplification unit having at least a first amplifier LNA for receiving a horizontally polarized wave signal, and a second amplifier LNA for receiving a vertically polarized wave signal. If a Tone/Pola signal is a signal indicating a power-saving mode, a control circuit of the first downconverter circuit causes both a local oscillator and a frequency converter to be in a non-operating state, controlling a bias circuit such that power is supplied to the first amplifier LNA.
