Abstract: A miniature transformer is provided at each end surface of a bobbin thereof with two spaced principal pins and two spaced dummy pins located between the two spaced principal pins. The dummy pin each is an integral extension from a rear end of an extended rear section of one adjacent principal pin embedded in the bobbin. The extended rear section extends obliquely forward toward a central area of the end surface of the bobbin and then turns straight forward to project from the end surface to form the dummy pin. The dummy pin each is provided at an inner side with a curved notch for a lead from windings on the miniature transformer to wind around there without further reducing a small distance between two adjacent dummy pins. Since the dummy pins are located between and shorter than the principal pins, they are protected by the principal pins without being easily touched or pulled to cause broken leads that would result in high bad yield in the production of the miniature transformer.

Abstract: A rotary operating-type electronic device used mainly in a peripheral apparatus such as a mouse for computers, portable telephones, an electronic device mounted on an automobile, and the like, in which a rotary type component and a linearly-driven type component are operated by a rotating manipulation of an operating knob attached to an operating axle and a tilting manipulation of the same knob in a direction orthogonal to an axis of the operating axle. The device is so constructed that the operating axle is supported to be rotatable together with a rotary encoder unit and also tiltable, by fitting an end of the operating axle in an axle-supporting portion having a non-circular center hole of a rotor of the rotary encoder. An operating knob of either a discal shape or a polygonal shape having a predetermined width is attached to an intermediate portion of the operating axle that protrudes from the rotor, and a push switch is disposed in a position to be in contact with another end of the operating axle.

Abstract: An assembly for supporting a personal electronic device includes a base and a holder. The holder is adapted to hold the device. The holder is removably connected to the base such that the holder may be selectively removed from and replaced on the base. Also, the holder is adjustably movably connected to the base such that the holder may be repositioned relative to the base. The device may thereby be reoriented relative to the base and, thus, a support surface, when mounted in the holder. A method for handling a personal electronic device includes mounting the device in a holder, mounting the device and the holder on a base, repositioning the holder relative to base to position the device as desired while the holder is mounted on the base, and removing the device and the holder from the base.

Abstract: An ignition coil that can be easily assembled, that assures co-axial alignment of a primary coil, a secondary coil and a center core part, and that generates desired high voltage. A core body is formed to have an outer diameter larger than that of a permanent magnet so that the permanent magnet will not protrude out of the outer peripheral face of the core body. Accordingly, when the center core part is inserted into a secondary spool, the center core part is not caught by the secondary spool and may be readily inserted and assembled therewith. Also, because no bulge is created at the center core part, it is possible to prevent the center core part from tilting within the secondary spool and to readily assure the co-axial alignment of the primary spool, the secondary spool and the center core part. Thus, voltage generated by the secondary coil is prevented from dropping, and high voltage may be applied to the ignition plug.

According to the invention, the at least two side walls (1b, 1c) each have at least one shoulder (1d, 1e), which subdivide the at least one winding space into a non-constricted first region (B1) and into at least one constricted second region (B2). In addition, the inductance element has electrical insulation (5), which bears on the at least one shoulder (1d, 1e) of the side walls (1b, 1c) and separates the non-constricted first region (B1) from the at least one constricted second region (B2).

Abstract: A small-sized heat resisting high voltage transformer and an ignition transformer using the high voltage transformer are provided and utilize both a heat resistant casting resin and a bobbin, which contain an inorganic filler. The high voltage transformer is capable of producing an output voltage of 10-35 kV and comprises a primary coil, a secondary coil, and a magnetic core, wherein a casting resin is injected into the coil part and subsequently cured. The casting resin and bobbin material used for making the coils have heat distortion temperature of at least 130° C., and contain an inorganic filler. The surface of the bobbin may be pretreated. Thereby, adhesion between a bobbin and a casting resin is enhanced to ensure operating properly under the sever heat cycle condition and provide a small-sized heat resistant high voltage transformer.

Abstract: A transformer comprises a printed circuit board having elongated conductors printed thereon, a ferrite core having a bottom mounted onto the printed circuit board and a flex circuit. The flex circuit comprises a dielectric sheet and elongated conductors printed on both faces of the sheet. The flex circuit is contoured around a top and sides of the core. The conductors of the flex circuit are surface bonded to respective conductors of the printed circuit board to form a series of primary windings and a series of secondary windings around the core. Provision of the upper portions of the windings by means of the flex circuit is economical because it does not require handling of discrete conductor portions.

The groove engages the engagement pieces, such that the anode lead wire is held by the anode lead holding device.

Abstract: A movable contact arrangement for a low-voltage circuit breaker which has a contact lever bracket equipped with contact levers and may move around a pivot bearing for opening and closing the circuit breaker. A journal, which engages with a bearing opening close to an inner end of a stationary conductor segment, is molded onto a main arm of the contact lever bracket. The journal is positioned more or less in the center and has a length that does not exceed the width of the contact arrangement. The bearing opening is also positioned within the width of the contact arrangement. This reduces the width of the circuit breaker, especially in multipole designs, while simultaneously improving the load carrying capacity and service life of the pivot bearing.

In an electronic appliance incorporating the revolving operation electronic component of the above structure, the clearance margin to be provided in relation to an operating knob and an aperture for the knob can be made small.

A button (12) is connected with the movable assembly (100). The button (12) is manually depressible toward the circuit board (14). A spring (220) biases the movable assembly (100) and the button (12) away from the circuit board (14). A plurality of angled surfaces (84, 92, 126, 172) on the movable assembly (100) cooperate to cause the movable assembly to rotate about the axis (22) when the button (12) is manually depressed toward the circuit board (14).
