摘要： A high density liquid is used to simultaneously transfer a liquid sample and a liquid reagent from antechambers formed in a centrifuge rotor to a transmissive measurement chamber formed in a radially outer region of the same rotor. The antechambers for the sample and the reagent and a reservoir chamber for the high density liquid are all elongated radially of the rotor and in fluidic connection through the radially outermost ends of the respective chambers. First the high density liquid is introduced into the antechambers so as to occupy a radially outer portion of each chamber, and then the sample and the reagent are introduced into the respective antechambers through their radially innermost ends. Thereafter the sample and the reagent are forced to flow out of the respective antechambers to enter the measurement chamber by additionally introducing the high density liquid into the reservoir chamber while the rotor is rotating.

摘要： Two guide members cooperatively constitute a chuck portion for holding a screw head. Opening and closing of the chuck portion is regulated depending on a mutual position between a machine body and a member into which a screw is driven. Guide pin portions of respective guide members engage with a stopper portion of a push lever until a screw is driven to a predetermined depth. The chuck potion tightly holds the screw head until a screw fastening operation is substantially finished, thereby suppressing the lifting of a machine body.

摘要： A vibration-damping apparatus for an electric hammer unit is provided. This vibration-damping apparatus is provided with the so-called transatory unit including elastic bars disposed between elastic damper members connected to a tool body and a handle of the electric hammer unit, respectively, for absorbing relative displacement of the elastic damper members caused by vibrations produced by the tool body during use. The vibration-damping apparatus further includes a stopper member attached to the elastic damper member attached to the handle so as to engage a chamber formed in the elastic damper member attached to the tool body for preventing the handle from being dislodged from the tool body even when the handle is swung laterally by a hammer operator. Additionally, each of the elastic bars includes a large-diameter portion and a small-diameter portion so as to allow the large-diameter portion to be deformed toward the small-diameter portion during the relative displacement of the elastic damper members for increasing the life of the bars.
摘要翻译：提供一种用于电锤单元的减振装置。该减震装置设置有所谓的转换单元，其包括分别设置在连接到工具主体的弹性阻尼器构件和电锤单元的手柄之间的弹性杆，用于吸收由振动引起的弹性阻尼器构件的相对位移在使用过程中由工具体产生。该减振装置还包括一个止动件，该止动件附接到安装在手柄上的弹性阻尼器件，从而与形成在安装在该工具主体上的弹性阻尼器件中的腔室接合，以防止手柄从工具主体上脱离，手柄由锤子操纵器横向摆动。此外，每个弹性杆包括大直径部分和小直径部分，以便在弹性阻尼器部件的相对位移期间允许大直径部分朝向小直径部分变形以增加寿命的酒吧。

摘要： A slipping torque changing mechanism for an impact tool includes a driving source for generating a rotational motion. A motion converting mechanism is connected with this driving source for converting the rotational motion of the driving source into a reciprocating motion. An impact mechanism is connected with this motion converting mechanism for transmitting the reciprocating motion to a tool end. A rotational motion transmitting mechanism is disposed separately from the motion converting mechanism for transmitting the rotational motion of the driving source to the tool end. A plurality of clutches, having different slipping torques, are disposed at different portions on the rotational motion transmitting mechanism.
