Abstract: The present embodiment relates to an electron multiplier or the like having a structure for realizing fast response characteristics as compared with the related art, and the electron multiplier includes at least a dynode unit, a stem, a coaxial cable, a conductive member, and a capacitor. The dynode unit includes multiple-stage dynodes, an anode, and a pair of insulating support members. An end portion of an outer conductor is drawn into the dynode unit together with an exposed portion of an inner conductor constituting a part of one end portion of the coaxial cable. With this configuration, it is possible to arrange the capacitor in a space between the dynode unit and the stem, and it is possible to fix the exposed portion of the inner conductor to a portion of the anode interposed between the pair of insulating support members.

Abstract: A drive force transmission device includes a motor, a transmission, a motor case, and a seal member. The motor is disposed in a dry space within a motor housing. The transmission is disposed in a wet space within a transmission case. The motor case covers an outer periphery of the motor housing and is coupled to the transmission case. The seal member is between the motor case and the motor housing and isolates the wet space and the outer space. The motor housing is divided into a divider wall housing dividing off the wet space and an outer wall housing dividing off the outer space, the divider wall housing being a material lighter than a material of the outer wall housing and integrally coupled thereto. The divider wall housing is divided from the outer wall housing at a position nearer to the dry space than the seal member.

Abstract: With a piezoelectric transformer formed of a ferroelectric element which generates a high voltage in a secondary section upon application of an AC voltage to a primary section, ground electrodes are attached to upper and lower surfaces of the secondary section of the piezoelectric transformer via a dielectric sheet for insulation in tight contact therewith such that a dielectric barrier discharge occurs around the ground electrodes to generate positive and negative ions, and an air flow is injected from an air nozzle to flow toward a neutralized subject across the ground electrodes.
