摘要:
A balanced-unbalanced conversion element for realizing easy adjustment of a phase balance of two balanced signals is provided. The balanced-unbalanced conversion element includes a first ¼-wavelength resonant line coupled to a first balanced terminal, a second ¼-wavelength resonant line coupled to a second balanced terminal, and a ½-wavelength resonant line. The ½-wavelength resonant line includes a first open-end-side line coupled to an unbalanced terminal and the first ¼-wavelength resonator and a second open-end-side line coupled to the second ¼-wavelength resonator. In addition, a width of the first open-end-side line differs from a width of the second open-end-side line.

A balanced-unbalanced transformation device includes a plate-like dielectric substrate having a ground electrode and a plurality of major surface electrodes formed thereon. Two of the major surface electrodes are connected to the ground electrode via short-circuit side surface electrodes so as to form ¼ wavelength resonator transmission lines. A third major surface electrode is disposed between the two major surface electrodes and has either end open so as to form a ½ wavelength resonator transmission line. A balancing characteristic adjustment side surface electrode is provided on a side surface of the dielectric substrate. By adjusting a capacitance formed between the balancing characteristic adjustment side surface electrode and the third major surface electrode, a phase balance between two balanced signals is set to a desired value.

A balance-unbalance conversion element that easily adjusts the phase balance between two balance signals. The balance-unbalance conversion element includes a dielectric substrate and an electrode pattern on a surface of the dielectric substrate. The electrode pattern includes a first ¼-wavelength resonance line coupled to a first balance terminal; a second ¼-wavelength resonance line coupled to a second balance terminal; a ½-wavelength resonance line having a first open end coupled to an unbalance terminal and the first ¼-wavelength resonator and a second open end coupled to the second ¼-wavelength resonator; and a balance characteristic adjustment electrode having a tip end opposed to a side of the ½-wavelength resonance line and a base end electrically coupled to a ground electrode. A center line of the electrode pattern on the surface of the dielectric substrate and the center of the tip end of the balance characteristic adjustment electrode are separated from each other.

The present invention provides a bag for packaging food products whose materials can be easily recycled. A bag for packaging food products is formed of a laminated film having a structure of polyester-type sealant layer with a low melting, point/barrier layer (vapor-deposited layer of ceramic or metal)/polyester-type heat resistant layer with a high melting point. The bag is formed by heat sealing the film such that the polyester-type low melting point sealant layer forms an inner side.

There is provided a container closure that can easily be manufactured, has improved drop strength and is convenient for opening operation. The present invention provides a container closure which includes a substrate having adequate property for retaining an object which is enclosed in a container, a peripheral section formed on the periphery area of the container closure on the opposite side of a side where the substrate is attached to a container body, a panel section covering an area of the substrate surrounding by the peripheral section on the same side where the peripheral section is provided, and a score section formed between the peripheral portion and the panel section to provide a weakened region. The peripheral section and the panel section is a plastic layer formed with the same heat-fusible plastic as the substrate. A substantial area of the score section is constructed of the substrate. Further, a thin layer is formed on at least a part of the score section with the heat-fusible plastic that connects the peripheral section and the panel section.

A stripline filter with wide-band filter characteristics having an attenuation pole on a high frequency side of frequency characteristics. The stripline filter includes at least three resonant lines, and two of the resonant lines include parallel line parts and bent parts. The third resonant line has a U shape in which both ends thereof are open and interdigitally coupled to the two resonant lines located on both sides thereof. The parallel line parts extend from base ends connected to a ground electrode via side surface lines that are parallel to respective line parts of the third resonant line. The bent parts extend so as to be bent from ends of the parallel line parts, and face each other at an interval.

In an electrically-driven piston pump including a fluid reservoir for retaining fluid that has leaked into a cam chamber, at an edge between a side wall surface of the cam chamber and the fluid reservoir, an upper edge, which is positioned on the upper side, is arranged so as to extend downward from the electric motor side toward the side away from the electric motor. With this arrangement, the fluid that has leaked into the cam chamber from a piston bore flows from the electric motor side toward the side away from the electric motor, coursing along the upper edge due to the gravity, and is thus introduced into the fluid reservoir.
