Abstract: In an impedance matching circuit, first to fourth inductors are formed by a conductor pattern of a coil shape, and a fifth inductor is formed by a conductor pattern of an unwound shape. The first inductor and the third inductor are respectively formed in different layers of a substrate and are arranged in such a relationship as to have coil openings overlapping each other. Moreover, the second inductor and the fourth inductor are respectively formed in different layers of the substrate and are arranged in such a relationship as to have coil openings overlapping each other. Two coils interposing the mounting position of the RFIC are in a 180° rotational symmetry relationship.

Abstract: Based on a result of repeated analysis of stress caused by application of an external impact in a circuit board, which is rectangular or substantially rectangular in plan view and includes mounting electrodes, included in an electronic component, the mounting electrodes near four corners of the circuit board, of the mounting electrodes provided on a back surface of the circuit board included in the electronic component, are provided at positions shifted from diagonal lines of the back surface. Hence, the stress produced near the four corners of the circuit board is reduced, and this can effectively prevent a fracture, a chip, and a crack from being caused in the circuit board.

The toothbrush contains a head having bristles implanted therein, a neck having the head attached to the distal end thereof and a holder for holding the neck. The head is a single piece or is composed of a plurality of head segments. The holder is provided at the distal end thereof with an adjuster for adjusting the length of the neck protruding from the holder.

Abstract: The present invention proposes an odor measuring apparatus capable of determining the similarity of the odor of an unknown sample with high objectivity and performing measurements with sensitivity similar to that of the human nose. According to a mode of the invention, an m-dimensional space is created from detection signals of m pieces of odor sensors, and a standard odor vector S1 representing the result of measurement of a standard odor and another vector Sx representing the result of measurement of an unknown sample are drawn in the space. Then, from the angle &thgr; between the two vectors, a degree of similarity is determined within the range from 0 to 100%, where the degree of similarity is corrected taking account of the difference in sensitivity between the odor sensor and the human nose.

The brush head 1 of the toothbrush has two or more brush segments 2a, 2b and 2c each having bristle bundles 6 implanted in a brush base 5, which are arranged in the axial direction of the toothbrush; and the brush segments are connected to each other with a resilient resin material, a rubber material, a spring, a rubber ligament, a magnet or other restoring means which permits restorable torsional and bending deformations in all directions with respect to the axis of the toothbrush; the restoring means having at the proximal end a neck 3 for fitting the brush head to the distal end of a handle 4.

Abstract: Provided is a toothbrush head which enables a single toothbrush to cope with any individual user's oral condition. The toothbrush head has bristle bundles, sponge pieces or the like implanted herein as a cleaning element on the bristling surface and contains unbristling areas formed on the bristling surface. Some or all of the bristle bundles are implanted asymmetrically with respect to the major central axis or the minor central axis of the head. The head can contain as separate parts bristling areas having bristle implanted therein and unbristling areas, which are removably attached to the head.

Abstract: A sample gas is introduced into a collecting pipe filled with a collecting agent to collect odor components therein, and a gas, such as nitrogen gas, is introduced into the collecting pipe to remove moisture and so on. Then, a heater is heated to raise a temperature of the collecting pipe so that a part of the odor components adsorbed by the collecting agent is separated therefrom, and then, a carrier gas is supplied to the collecting pipe to send the separated odor components to a sensor. After a predetermined time has passed, the heater is further heated to send the separated odor components to the sensor. The heater may be further increased. Thus, an output information of the gas sensor in one cycle of measurement can be increased.

Abstract: In a method of manufacturing moldings and an apparatus therefore, a ridge piece 20 protrudes from a molding main body 10 of a molding 1 in a lip manner is removed gradually from a leading end side to a root side by a lip removing piece 33 moving together with a second die 32 which changes the extrusion contour of the molding main body 10, then the ridge piece 20 is removed by the movement of the second die 32 without decreasing the thickness of the ridge piece 20 thinning. Accordingly, the ridge piece 20 can be removed effectively by the simple operation and apparatus without requiring the operation such as the after-treatment, which can result in the improvements of the productivity of the molding 1, the appearance of the molding 1, and the reliability.
