Abstract: A video signal processing apparatus comprising an oscillating unit for outputting a signal of a stable frequency, a counting unit for counting the period of a cycle of a signal supplied from the outside based on the signal output by the oscillating unit, a clock number calculating unit for calculating the number of clocks in a line based on a result of counting by the counting unit, a comparing unit for comparing the number of clocks calculated by the clock number calculating unit with a threshold to decide which is larger, a switching unit for deciding the number of clocks in the next operation by switching to the number of clocks calculated by the clock number calculating unit if the calculated number of clocks is larger than the threshold, or deciding the number of clocks in the next operation by holding the number of clocks in a line in the current operation as it is, and a synchronizing signal generating unit for, based on the number of clocks in operation decided by the switching unit and the signal out

Abstract: There is provided a data memory apparatus which can efficiently use a general-purpose DRAM as a memory used during the digital data error correcting and modifying processing. The apparatus is comprised of a DRAM, a DRAM access unit and an error correcting circuit. Input digital data is first subjected to the error correcting processing by means of the error correcting circuit, assigned with a result of the error correcting processing and transferred to the DRAM access unit. The DRAM access unit accesses the DRAM in a page mode to store the data in the DRAM.

Abstract: An optically active (+)-4,4,4-trifluoro-3-(indole-3-)butyric acid is produced by a method which consists essentially of causing 2,2,2-trifluoroethanol to react on a racemic modification 4,4,4-trifluoro-3-(indole-3-)butyric acid thereby forming a reaction solution containing the trifluoroethyl ester of the butyric acid, causing an enzyme having an esterase activity to act on the reaction solution thereby forming an optically active (+)-4,4,4-trifluoro-3-(indole-3-)butyric acid, and thereafter separating the reaction product from the reaction solution.

Abstract: An agent for increasing the sugar content and/or decreasing the acid content of plant fruits has as a substantial main component thereof a fluorine-containing .beta.-indolebutyric acid compound represented by the general formula ##STR1## (wherein Y stands for one member selected from the class consisting of hydroxyl group, alkoxy group, amino group, and alkyl amino group and R.sup.1 and R.sup.2 independently stand for one member selected from the class consisting of hydrogen atom, halogen atom, alkyl group, alkoxy group, aryl group, nitro group, amino group, and alkyl amino group). A method for producing ripe fruits having a high sugar content and/or a low acid content by causing the fluorine-containing .beta.-indolebutyric acid compound mentioned above to adhere to unripe fruits on plants and plants bearing fruits and subsequently allowing the fruits to mature.

Abstract: A substituted fluorine-containing .beta.-indolebutyric acid compound represented by the formula: ##STR1## wherein Y stands for one member selected from the group consisting of hydroxyl group, alkoxy group, amino group, and alkylamino group, at least one of R.sup.1 and R.sup.2 stands for one member selected from the group consisting of halogen atom, alkyl group, alkoxy group, aryl group, nitro group, amino group, and alkylamino group, and the remaining one, if any, for a hydrogen atom, a plant growth regulating agent having as a substantial main component thereof the substituted fluorine-containing .beta.-indolebutyric acid compound, and a method for regulating the length of roots sprouting from plant seeds and the length of hypocotyls by causing adhesion of the substituted fluorine-containing .beta.-indolebutyric acid compound to the plant seeds.

Abstract: A helical scan type digital recording/reproducing apparatus arranged such that data corresponding to m fields/frames are divisionally recorded in n tracks on a magnetic tape and a slow, still or frame advance reproduction mode is effected in response to an instruction from an external input. The apparatus is equipped with a signal processing circuit coupled to a rotary head for inputting data reproduced from the magnetic tape by the rotary head to store the reproduced data in a memory. In response to the instruction for the slow, still or frame advance reproduction mode, the signal processing circuit outputs a control signal when the data corresponding to one or more frames/fields are stored in the memory. Also included is a servo circuit coupled through a signal line to the signal processing circuit to be responsive to the control signal from the signal processing circuit. The servo circuit controls a capstan motor in accordance with the control signal and the reproduction mode instruction.

Abstract: Tetrafluoroterephthalonitrile is produced by mixing tetrachloroterephthalonitrile, dry powdered potassium fluoride and a polar solvent having a water content of not more than 0.2% by weight and heating the resultant mixture with simultaneous agitation.
