A method of selecting a barley variety comprising: a heat treatment step of heat-treating a crude enzyme solution extracted from a seed of a barley (e.g., at 57.5° C. for 30 minutes); an activity-determining step of determining the enzyme activity of β-amylase in the crude enzyme solution heat-treated; and a selection step of selecting the barley variety containing a β-amylase having a residual activity of from 85 to 90% as a result of the activity determination.

The blind rivet for fastening together a plurality of mounted components with mounting holes comprises a rivet body having a sleeve, a flange and a through hole; a mandrel having a slender stem and a head; and a washer. The head of the mandrel is adjacent to the sleeve-side end portion of the rivet body, the stem of the mandrel extends through the rivet body from the flange-side end portion, and the washer is mounted near the flange on the outer periphery of the sleeve of the rivet body. A portion of the outer peripheral surface of the sleeve adjacent to the flange is swaged to form a recessed portion so that the diameter in the other position is enlarged. The washer is pushed onto the enlarged-diameter portion and secured. The mounted components are fastened together between the enlarged end portion of the sleeve and the washer.

A container 1 has a support member 3 which ascends and descends freely and is provided at back of a container body 2, a top connecting member 11 which is fixed at front of the container body 2 and can couple and decouple with a carrier 45, a bottom connecting member 16 which is provided at the front of the container body 2 so as to be able to move and which couples and decouples with the carrier 45, and transmitting members 21, 40 which transmit the movement of the bottom connecting member 16 to the support member 3 and raise and lower the support member 3. When this container 1 is loaded on the carrier 45, it is possible to synchronize the front and back of the container body 2 so that the container 1 remains level by raising the front of the container 1 by lifting the top connecting member 11 at the front of the container body 2 by means of a member 61 of the carrier 45, and holding the bottom connecting member 16 at the front of the container 1 fixed with respect to the ground, transferring the motion of the bottom connecting member 16 relative to the container body 2 to the support member 3 at the back of the container 1 by means of the transmitting members 21, 40, and extending the support member 3 at the back of the container 1 down to raise the back of the container 1.

摘要:
A multifunction apparatus for the direct heat treatment of a medium- to high-carbon steel rod in a lower quench line and the treatment of low carbon steel in an upper quench line. A hot-rolled rod is transported on a conveyor in the form of a sequence of non-concentric rings, the conveyor, being operative between a first position in contact with the lower quench line and a second position in the upper cooling line. In the lower quench line the rod is subjected to controlled cooling in a coolant so that the greater part of any austenite in the entire length of the rod is substantially uniformly transformed to a fine pearlite structure. A heat holding vessel is operated under conditions that transforms any residual defects into pearlite.

An AM signal transmitter for generating an amplitude modulated carrier comprises a voltage-increasing stage and a power-increasing stage. The voltage-increasing stage includes a pulse width modulator, responsive to an input modulation signal, for producing a pair of high frequency pulse trains which are modulated in width in a complementary fashion. The pair of pulse trains are respectfully fed to a pair of switching and amplifying elements arranged in push-pull fashion. The output of the switching and amplifying elements is processed through a low pass filter to eliminate high frequency components, and is stepped up in voltage by processing through a voltage step-up transformer. The output of the voltage step-up transformer is then fed to the power stage of the AM signal transmitter, which include a power amplifier. Both the power amplifier and the switching and amplifying elements can be powered from a single power source. Other embodiments of the invention can be realized.
摘要:
In a vehicle seat, two front links and two rear links are pivotally connected between a seat cushion frame and a floor of vehicle. One of the two front links is of a sector shape having an arcuate gear region meshed with a drive pinion. Or alternatively, both of the two front links may be of such sector gear configuration, such that one front link is engaged with the drive pinion and the other front link engaged with a free-to-rotate pinion. Hence, both two front links are robust enough to withstand an excessive great load in the case of rear-end collision. By contrast, the two rear links are simply prone to deformation by the excessive great load. Accordingly, the excessive great load is to be intensively exerted upon those two rear links which will in turn be deformed quickly to absorb a corresponding excessive great impact.
