A line filter includes a magnetic core having a leg. A bobbin is placed around the leg of the magnetic core. The bobbin has end collars provided with projections respectively. A pair of windings are provided on the bobbin. A molded casing made of resin houses the magnetic core, the bobbin, and the windings. The casing has movable tongues which engage the projections on the bobbin collars to fix the bobbin to the casing. The casing has inner surfaces formed with ribs which engage the magnetic core to fix the magnetic core to the casing. The casing has an L-shaped movable member extending from a ceiling thereof and engaging the magnetic core to fix the magnetic core to the casing.

摘要:
The present invention relates to a line filter that is characterized by suppressing magnetic adverse effects inflicted on other components due to leakage magnetic fluxes from the closed magnetic circuit core used in the line filter and at the same time preventing noises from infiltrating into the closed magnetic circuit core. The line filter comprises a synthetic resin made bobbin (5) having flanges (2) on its both ends and a through hole (20) along its axis, a square shaped closed magnetic circuit core (1) with one of its magnetic legs inserted in the through hole (20) of the bobbin (5), windings (6) wound between both flanges (2) of the bobbin (5) in the direction perpendicular to the bobbin's axis, metal terminals (9) embedded in the flanges (2) and connected with the windings (6) and a wobbling preventive means to prevent the closed magnetic circuit core from wobbling.

The present invention is intended to provide a line filter having an outstanding attenuation characteristic over a wide frequency band from low frequency band to high frequency band, with an improved elimination characteristic for common mode noises. To achieve this object, the invention incorporates a structure wherein a first coil unit (14) for second band and a second coil unit (16) for second band are disposed vertically to a closed-loop magnetic core (11).

A line filter assembly adapted to be inserted in an electrical power supply circuit of various electronic appliances for avoiding an invasion and leakage of noise include first and second core members each having a pair of opposite arms connected together through a common bridge. Coils are formed on the arms of each of the core members in such a manner that directions of magnetic fluxes produced in the closed magnetic circuit as a result of flow of line currents counteract while the same coils are so arranged that the magnetic fluxes produced in the closed magnetic circuit as a result of the flow of the line currents are oriented in the same direction.

[Problem]If lidocaine is composed of non-aqueous patch, the adhesive power of the preparation tends to get lower, as the composition amount of lidocaine is higher. It is popular to solve lidocaine in dissolving agent in order to compose lidocaine in patch and release effective amount into skin. However, if the amount of dissolving agent gets higher, the adhesive power gets extremely lower, so that an long-time attachment is difficult.[Solution]A non-aqueous patch comprising lidocaine and/or its reactant, and a dissolving agent which are contained in a base of plaster, the plaster being hold by a support, of which strength of 50% stretched to longitudinal direction is less than 2,000 g/50 mm and of biaxially-oriented stretch cloth.

An ester compound represented by formula (1): wherein R1 represents hydrogen, fluorine, C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkoxymethyl, or C1-C4 alkylthiomethyl; R3 represents hydrogen or methyl, R4 represents hydrogen or C1-C4 alkyl, and R5 represents hydrogen or C1-C4 alkyl; has an excellent pest control effect and is therefore useful as an active ingredient of a pest control agent.
摘要:
Singar is identified as a novel molecule, whose expression is varied before and after the polarization of a nerve cell, and occurs in the tip of an elongating axon, called a growth cone, which is important for the formation or elongation of an axon. Singar is expressed specifically in the brain and the amount of Singar expression is largely increased in an individual during periods where the formation of axons is increased. It is observed that Singar is highly enriched in the growth cone at the tip of an axon. When the expression of Singar is inhibited in nerve cells in culture, the formation of multiple axons is induced. Thus, the inhibition of Singar can induce axon formation. Therefore, by inhibiting the expression or activity of Singar, it becomes possible to induce or promote the formation or elongation of an axon in a nerve cell.
