摘要： A front stage circuit of a transformer includes a switch series unit, capacitors, and a ground electrical path. The switch series unit, connected in parallel to a power supply, includes odd-numbered/even-numbered switches configured to be alternately turned ON. Assuming that mutual connection points of the switches and points at both ends of the switch series unit are m nodes in total, and one of the points at the both ends is a ground node, the capacitors are provided on at least one of a first electrical path that combines odd nodes and leads them to a first output port, and a second electrical path that combines even nodes and leads them to a second output port, and the capacitors are present to correspond to (m−1) nodes excluding the ground node. The ground electrical path connects the ground node directly to the first output port without an interposed capacitor.

摘要： A method for manufacturing a spin wave excitation/detection structure to excite and detect a spin wave. The method includes: forming an insulating magnetic film on a donor substrate, producing a bonded substrate by bonding a surface of the insulating magnetic film on the donor substrate to a surface of a support substrate via a conductive film, removing the donor substrate from the bonded substrate, and forming a conductive line on the insulating magnetic film. The spin wave excitation/detection structure includes the support substrate, the conductive film provided on the support substrate, the insulating magnetic film provided on the conductive film, and the conductive line provided on the insulating magnetic film. This provides the method that can manufacture the spin wave excitation/detection structure, having a structure with high strength, the spin wave that can be excited with high intensity, and the spin wave that can be excited with broad frequency bandwidth.

摘要： Powder particles for forming a homogeneous green body having a sufficient strength and a process for producing a green body by using the powder particles. A green body is shaped by using powder particles of composite particles in which thermoplastic resin particles are scattered on surfaces of large particles in an amount within a predetermined volume ratio range with respect to the large particles, and loaded to form resin pools in contact point peripheral areas of adjoining ones of the large particles and form voids in areas other than the contact point peripheral areas when the thermoplastic resin particles are melted. A green body packed with the powder particles each having a small amount of the thermoplastic resin particles attached thereon is placed under a melting condition of the thermoplastic resin particles, the thermoplastic resin is melted and gathers around contact points (or proximal points) of the adjoining powder particles.

摘要： An exogenous substance transfer apparatus that introduces an exogenous substance into a small amount of cells by electrical action and a method for manufacturing exogenous substance-bearing cells at low cost are provided.In the introducing an exogenous substance like a gene into a cell, a cell suspension liquid that contains the cell and the exogenous substance is supplied to a container through an opening portion in an amount that is prepared such that a liquid droplet that is formed will not come into contact with a pair of electrodes simultaneously. The liquid droplet is formed in an oil stored in the container, without the cell suspension liquid mixing with the oil. When a direct current voltage is supplied to the electrodes from a power supply, the liquid droplet moves there-between, and the exogenous substance is introduced into the cell within the liquid droplet by electrical action.

摘要： A transformer includes a front stage circuit and a rear stage circuit. As a front stage circuit, a switch series unit, which is connected in parallel to a power supply, includes odd-numbered switches and even-numbered switches alternately turned ON. Mutual connection points of the respective switches and points at both ends of the switch series unit are regarded as m nodes in total. Capacitors are provided on at least one of a first electrical path combining odd nodes to lead them to a first output port, and a second electrical path combining even nodes to lead them to a second output port. The capacitors are present so as to correspond to at least (m−1) nodes. The rear stage circuit includes an element series unit, which is composed of a pair of semiconductor elements connected in series to each other for conducting operations of mutually opposite polarities, and necessary inductors.
