Abstract: By the selective use of a homogeneous stable precursor solution in which no polymerization reactions immediately occur and which contains aromatic compounds such as pyrrole, thiophene, aromatic amines or their derivatives, oxidizing agents, and solvents, as a precursor solution of conductive polymer film, a homogeneous and tough conductive polymer film can be obtained when the said precursor solution is cast on a substrate and the solvents are evaporated to remove.

Abstract: This invention relates to 3,6-diamino-2,5-pyrazinedicarbonitrile which is a red crystal and yellowish green fluorescent substance and the methods of preparation from compounds represented by formula [I], ##STR1## (wherein R are aryl, alkyl, aralkyl or alkenyl or may be substituted), as a starting material, under acidic condition in the presence of oxygen.

Abstract: A pyrrole polymer membrane having electrical conductivity and liquid crystal properties in the same matrix. The starting pyrrole monomer derivative is illustrated by the formula ##STR1## where R.sub.1 and R.sub.2 are selected so that at least either of them is an electron attractive group. Methods of producing such membranes by a electropolymerization process and by a chemical oxidation process are described.

Abstract: Aminoacetonitrile derivatives, where the 2-position of aminoacetonitrile is optionally substituted by alkylthio groups, arylthio groups and heterocyclicthio groups. The process for making such compounds comprises reacting hydrogen cyanide with the desired corresponding R-S-H and recovering the crystallized salt thereof. The aminoacetonitrile derivatives are useful as starting materials to produce pharmaceutical and agricultural intermediates such as benzomide derivatives with fungicidal and herbicidal activities.

Abstract: A spring clip for a heat seal connector used to secure a thermocompression bonded portion of a heat seal connector in a manner not to be peeled off by an external force is disclosed. The spring clip is used in order to hold a thermocompression bonded portion with a fine pitch of a terminal portion in a heat seal connector, and designed so that a spring portion and a holding portion are formed continuously and lengthily, and a plurality of punched portions to weaken a spring pressure are provided at fixed intervals only on the side of the spring portion.

Abstract: A refrigeration cycle is a closed cycle constituted by a variable power compressor, a four-way valve, an indoor heat exchanger, an expansion valve and an outdoor heat exchanger. Air-conditioned air is supplied from the refrigeration cycle to a plurality of rooms to be subjected to air conditioning through a supply duct at a portion near a supply opening for supplying the air-conditioned air to a corresponding one of the rooms and controls a flow amount of the air-conditioned air supplied from the supply opening. Air is returned from each room to the refrigeration cycle through a return duct. The indoor heat exchanger of the refrigeration cycle has a temperature sensor for detecting the temperature of the indoor heat exchanger. A system controller controls a drive frequency of the variable power compressor of the refrigeration cycle in accordance with a difference between the temperature of the indoor heat exchanger detected by the temperature sensor and a preset temperature of the indoor heat exchanger.

Abstract: A test pattern projector built into a color television camera, for adjusting the camera to desired conditions in order to attain a favorable quality of image immediately before use. A test pattern chart is illuminated with an illuminating light of an adjusted color temperature, forming an image of the test pattern chart on an image pickup apparatus. The color temperature adjustment of illuminating light emitted from a light source is effected by using a color temperature conversion filter and a color compensating filter both disposed in front of the light source. An interference filter or an absorbing filter with a wedge shape in cross section can be employed as the color compensating filter. The color correction depends, in the former, on the inclination thereof relative to the optical axis and, in the latter, on the thickness thereof intersecting the optical path.

Abstract: Compounds having the formula ##STR1## wherein R.sub.1 denotes hydrogen atom, halogen group atom or methyl radical,R.sub.2 denotes cyclohexyl radical, phenyl radical or phenyl radical substituted with methyl radical or nitro radical, andX denotes oxygen atom or sulfur atom,are useful for the control of phytophthora diseases and downy mildew of vegetable and fruit trees.The compounds of formula [I] can be prepared by reacting compounds having the formula ##STR2## wherein R.sub.1, R.sub.2 and X are defined previously, are reacted with a carbonic acid derivative in the presence of an acid-binding agent.

Abstract: A compound of the formula ##STR1## wherein typical representations of X, Y and Z is oxygen or sulfur; R.sub.1 is methyl; R.sub.2 is phenyl substituted with chlor, methyl, methoxy, nitro or methylenedioxy; and R.sub.3 is cyclohexyl, methylcyclohexyl or tetrahydropyranyl, is useful as an acaricide.
