Abstract: Although a variety of pest control agents have been used for many years, many of these pest control agents have various problems, such as insufficient effectiveness, and restriction on use thereof due to resistance acquired by pests, and the like. Therefore, it is desired to develop a novel pest control agent that is less likely to have such drawbacks. One of objects of the present invention is to provide a highly active compound or a salt thereof against a pest. The present invention relates to an N-(4-pyridyl)nicotinamide compound represented by the following formula (I) (in the formula (I), for each substituent, see Description) or a salt thereof.

Abstract: An industrial X-ray tube formed by accommodating a cathode and anode in a container having an evacuated interior, in which electrons emitted from the cathode are caused to strike the anode and X-rays are emitted from the anode. The cathode is formed from graphite. The graphite is a layered crystal obtained by layering a plurality of carbon hexagonal planes. The graphite is cut based on crystal axes of the carbon hexagonal planes. The resulting cut surface is caused to function as an electron-emitting surface. For example, directions of an a- and b-crystal axis may be set so as to be arbitrary between each of the layers of the carbon hexagonal planes, the graphite may be cut along a surface parallel to the c-axis, and the resulting cut surface may be caused to function as an electron-emitting surface. The graphite may also be cut along a surface orthogonal to the c-axis.

A lead wire extending from the cathode to the outside of the X-ray tube is connected to the high-voltage terminal of the booster circuit. A molded member containing insulating resin is formed to shield at least a cathode side end part of the X-ray tube, the lead wire outwardly extending from the cathode side end part and a high-voltage terminal side end part of the booster circuit.

Abstract: Input terminals to which two types of serial data with similar formats are sent are disposed. Video data sent to the normal dubbing input terminal is data that has not been compressed/encoded. Data sent to the straight dubbing input terminal is data that has been compressed and encoded. Data received from the input terminal includes a sync error flag (error flag for each sync block) that is OR output data of data added by a reproducing VTR and transmission error information. The sync error flag is sent to an ECC encoder through a format converter not through an BRR encoder. An output signal of an ECC encoder is recorded to a magnetic tape by recording heads through a recording driver.

Abstract: A line number LN is extracted from serial data corresponding to BTA S-004 standard. The line number LN is placed as LN0 and LN1 to each of a luminance signal Y and color difference signals Pr/Pb of a 4:2:2 signal. The 4:2:2 signal is converted into a 3:1:1 signal by a bandwidth-compressing means. In addition, the 3:1:1 signal is re-arranged to two-channel signals Ch0 and Ch1 with the same format at a transmission rate of 46.40625 MHz. Thereafter, the, signals are processed at the transmission rate of 46.40625. The line number LN is placed as LN0 and LN1 at the beginning of one horizontal interval.

Abstract: Reproducing heads reproduce signals from a tape in advance of recording heads for a time period equivalent to a system delay. An ECC decoder corrects an error of a signal received from each reproducing head. A BRR decoder decompresses and decodes the signal received from the ECC decoder. A concealing circuit interpolates the signal received from the BRR decoder. An output signal of the concealing circuit is sent back to a selector of the recording system. The selector switches between a signal received from an input terminal and the reproduced signal at the end of each field. An intra-field encoding process or an intra-frame encoding process can be selected as an compressing and encoding process. Information that represents the selected encoding process is recorded on the tape.

Abstract: A digital audio and video signal recording system and method wherein erasure of a channel has no major effect on adjoining audio signals in the case of high density recording. The same channel of audio signals are recorded arranged in blocks in a direction orthogonal to the helical track of the magnetic tape. There is a possibility of the occurrence of error at the two outside tracks due to narrowing of the tracks at the time of editing of a channel, but preferably an outer code is added to enable erasure correction.

Abstract: In a method for recording and/or reproducing digital data, such as digital audio signals recorded simultaneously with video signals, dividing sampling data composed of a plurality of bits into higher order bits and lower order bits, constituting error correction coding blocks by only the higher and lower order bits of the sampling data of a plurality of samples respectively, thereby making it possible to easily realize adaptive error checking in the course of the block-by-block error checking in association with, for example, data criticality.A sync word and a block address are affixed to the error correction coding block constituted in that manner. Since one block address is formed using the address data of two or more blocks, a broader address space can be obtained even when the bit number of the address area of each block is few.

Abstract: In a high definition television system (HDTV), a video signal is recorded on and reproduced from oblique and successive parallel tracks on a magnetic tape, and an audio signal is recorded on and reproduced from a plurality of parallel tracks extending in a longitudinal direction of the tape. The tape is transported in its longitudinal direction during recording and reproduction. A tape position adjuster adjusts the position of the magnetic tape in its transport direction, and first and second transducing heads located at positions separated by a predetermined distance which may vary slightly because of manufacturing tolerances are employed for respectively reproducing and recording the audio signal. When the tape is edited, a processor connected to the first transducing head processes a reproduced audio signal and supplies it to the second transducing head, which records it accordingly.

Abstract: In the transmission of digital video data signals, for example, in a digital video tape recorder, a luminance signal and first and second chrominance signals, such as R-Y and B-Y, are individually sampled to provide respective digital luminance data signals and first and second digital chrominance data signals for forming a high-definition video picture. Time code data signals representing the corresponding frame including the sampled signals are provided as individual sets of identical signals. The digital luminance data signals and the first and second digital chrominance data signals are divided into respective sets thereof which each consist of two successive data signals.
