Abstract: This invention is intended to identify a gene cluster involved in biosynthesis of a cyclic peptide compound produced by a filamentous fungus of the Curvularia species and to establish a system for synthesizing such cyclic peptide compound. The gene is composed of a first module to a tenth module and encodes a protein having activity of synthesizing a nonribosomal peptide constituting a basic peptide backbone of a cyclic peptide compound produced by a filamentous fungus of the Curvularia species.

Abstract: An impact test hammer includes a cylindrical handle having opposite first and second end portions and a hollow interior, a sensor portion fixed to the first end portion of the handle, and a grip portion fixed to the second end portion of the handle. An elastic striking portion is fixed to an outer periphery of the sensor storage portion, and an impact acceleration sensor is housed within the sensor storage portion for sensing a striking power of the elastic striking portion applied to a test object. A circuit is housed within the grip portion and operatively connected to the sensor by way of wiring extending through the hollow interior of the handle. Such a circuit includes a range switch, a scale conversion amplifier and a wind amplifier. A knob is provided on the outer periphery of the grip portion for operating the range switch to set a degree of amplification of the amplifier.

Abstract: An electronic component testing laminated board suitable for performing a heat test on electronic components of a multikind and small quantity production type. The laminated board includes a metal plate, a testing circuit layer including a double-sided printing wiring board or the like and integrally formed through a thin electric insulating layer on one side of the metal plate for mounting thereon electronic components to be tested, and a heater circuit layer including a metal foil circuit or the like and integrally formed through another electric insulating layer on the other side of the metal plate for maintaining the testing circuit layer at a given temperature. An inorganic filler or the like is added to the electric insulating layers. An electronic component testing box for removably accommodating the electronic component testing lamianted board includes walls made of a heat insulating material, power supply connecting connector, signal input and output connector, temperature measuring apparatus, etc.
