Abstract: A frame processing circuit performs frame processing that is creation processing of creating an RFID data frame from a payload or analysis processing of analyzing an RFID data frame and obtaining a payload. The frame processing includes m (1?m?n) number of processing steps according to a type of data frame among n (n is an integer of 2 or above) number of processing steps. The frame processing circuit includes n-number of processing blocks that respectively execute the n-number of processing steps. The n-number of processing blocks include a bypassable block where setting of whether to bypass processing can be made according to a type of data frame, that performs processing of a relevant step on received data and outputs processed data if no bypassing is set, and outputs received data without performing any processing if bypassing is set.

Abstract: A to be-processed portion of an inner panel formed by stamping a steel plate is overlaid, in a thickness direction thereof, with a to-be-processed portion of a reinforcing member formed by stamping a steel plate. The inner panel and the reinforcing member are joined and integrated by a spot welding apparatus, thereby obtaining an intermediate article. A material handling robot puts off the intermediate article from the spot welding apparatus, conveys it to a pressing apparatus, and sets it against the pressing apparatus. The to-be-processed portion of the inner panel and the to-be-processed portion of the reinforcing member are subjected to piercing by the pressing apparatus.

Abstract: An industrially more advantageous method for the production of metabolites biologically synthesized via phosphoribosyl pyrophosphate (PRPP) is provided, making use of metabolically modified strains in which transketolase activity is deficient or reduced in comparison with the parent strain.

Abstract: The present invention provides a process for producing an L-amino acid which comprises culturing in a nutrient medium a microorganism which is capable of producing the L-amino acid and which can not grow in a synthetic medium containing said L-amino acid as the sole nitrogen source in an amount of 5 mg/ml or below, allowing the L-amino acid to accumulate in the culture, and recovering the L-amino acid from the culture.

Abstract: In tracing a tape with a signal recording head to form tracks having digital data recorded thereon, a plurality of tracks provide each of blocks, and a usual playback data area NA and trick playback areas TH and TL are arranged on each of the tracks included in each block. The trick playback areas are enlarged to provide increment areas TA with a decrease in the bit rate of usual playback data. In recording image data as to a plurality of programs on a tape conjointly, signal recording tracks are formed on the tape, and a usual playback data area and a trick playback data area are formed on each of the tracks or on one track per plurality of tracks, as arranged longitudinally of the track, whereby the image data as to programs A to D is conjointly recorded on the same tape.

Abstract: Disclosed are a vinyl chloride-based polymer-polyurethane composite comprising vinyl chloride-based polymer (1), polyurethane, plasticizer (4), metal salt of higher fatty acid (6) and hydrocarbon-based lubricant (7), the metal of metal salt of higher fatty acid being at least one element selected from a group consisting of magnesium, zinc and lead, which have low hardness and excellent hydrolysis resistance, compression set characteristic and profile extrusion moldability, and a method of producing vinyl chloride-based polymer-polyurethane composite which is produced by means of of heating, melting and mixing not less than 200 parts by weight to not more than 800 parts by weight of polymer polyol (2), isocyanate compound (3) with three or more isocyanate groups in amount of the molar ratio of isocyanate group in isocyanate compound (3) to hydroxyl group in polymer polyol (2) being not less than 0.3 to not more than 0.

Abstract: The present invention provides a process for producing an L-amino acid which comprises culturing in a nutrient medium a microorganism which is capable of producing the L-amino acid and which can not grow in a synthetic medium containing said L-amino acid as the sole nitrogen source in an amount of 5 mg/ml or below, allowing the L-amino acid to accumulate in the culture, and recovering the L-amino acid from the culture.

Abstract: A process for the production of L-threonine by fermentation of Escherichia coli FERM BP-3756 or Escherichia coli FERM BP-4072 and a process for the production of L-isoleucine by the fermentation of Escherichia coli FERM BP-3757 is disclosed. The strains are resistant to purine analogues such as 6-dimethylaminopurine or 6-methylaminopurine.

Abstract: Disclosed is a process for producing L-threonine, which comprises culturing an L-threonine-producing microorganism belonging to the genus Escherichia and having a resistance to at least one of L-phenylalanine and L-leucine in a medium until L-threonine is produced and accumulated in the culture, and recovering L-threonine therefrom.

Abstract: A disc player for playing a first disc having data recorded on both sides thereof and also a second disc having data recorded on only one side thereof has disc drive means loadable with one of the first and second discs selectively. Whether the disc loaded on the drive means is the first disc or the second disc is detected from the data read by pickup means. When the second disc is detected, the pickup means is positioned for the data recording side of the second disc automatically so as to reproduce signals therefrom. Accordingly, even if the second disc is loaded with the disc side oriented erroneously, the data can be read from the recording side at all times.

Abstract: An apparatus for reproducing signals from both sides of a disc which comprises a detector for detecting that the signal reproduction side of the disc opposed to the pickup is being changed over from one side to the other side, and a device for notifying the user that the reproduction side is being changed over according to an output signal from the detector. The notifying device enables the user to properly recognize the state of the pickup during the travel thereof between the both sides of the disc.
