Abstract: In a headphone which inhibits noise generated within an ear structure by vibration transmitted through bone, head motion based on vibration is detected by a motion sensor, and a motion signal is output. This motion signal is delayed by a delay time, and the phase of the motion signal is inverted to generate a first noise cancelling acoustic signal in the first cancelling circuit. An acoustic driver of the headphone is driven by the first noise cancelling acoustic signal to inhibit noise.

Abstract: An obliquely bent spring tab is projected from a circumference of a bolt hole in a power connector of a bus bar. When the bus bar is housed in and fixed to a case, the spring tab is in stable surface contact with a bolt. Thereby, conductivity inspection can be performed by connecting a conductivity inspection apparatus to the bolt.

Abstract: Upper and lower casings (10, 11) are coupled together and are fixed to a holder (20) by a bolt (B). The upper casing (10) has an upper wall (10b) with a bolt hole (11c) and the lower casing (11) has a bottom wall (11b) with a bolt hole (11c). A cylindrical collar (15) is molded with the bottom wall (11b) of the lower casing (11) and projects from the edge of the bolt hole (11c). The collar (15) has a length to penetrate through the bolt hole (10c) in the upper wall (10b) of the upper casing (10). The collar (15) has a step (15a) for supporting a lower surface of a bolt head (Bb) of the bolt (B) and inward projection (15b) for engaging an upper surface of the bolt head (Bb). Thus, the bolt head (Bb) is held rotatably between the step (15a) and the inward projection (15b).

Abstract: The invention provides an indoor LAN system, including: a distributor for distributing or delivering a television signal having a frequency band contained in a first frequency band, and a LAN signal having a frequency band contained in a second frequency band to a plurality of common antenna terminals provided in a plurality of rooms through house wirings, respectively; a television•LAN signal-separating apparatus for receiving as its inputs the television signal and the LAN signal through corresponding one of the plurality of common antenna terminals provided in the plurality of rooms, respectively, and outputting the television signal and the LAN signal to a television signal-outputting portion and a LAN signal-outputting portion, respectively, through signal separation; and a display device for processing at least one of the television signal and the LAN signal separated from each other in the television•LAN signal-separating apparatus.

Abstract: In a structure for attaching a circuit board terminal to a circuit board, stress is minimized in a soldered portion on a circuit section upon inserting and drawing an electrical element into and from the circuit board. The attaching structure including a holding member mounted on and secured to a circuit board, a bus bar that has a base portion supported on the holding member and a leg portion that passes one or more through-holes and to be soldered on a circuit section, and a circuit board terminal that has a base portion to be connected to the bus bar and a connection portion adapted to be coupled to a terminal of an electrical element. The bus bar is provided on the base portion with elastic tongue pieces that can contact elastically with a circuit board terminal. The circuit board terminal is connected through the bus bar to the circuit section.

Abstract: An automotive electrical connection box (10) has a casing main body (11) fastened to a holder (20) by a bolt (B). A mating connector (12) is mounted in the casing main body (11) and is connected with a waiting-side connector (21) in the holder (20) simultaneously with the fastening by the bolt (B). A dummy housing (13) projects from the casing main body (11) at a side of the bolt (B) opposite the mating connector (12), and an opening (22) is provided at a portion of the holder (20) corresponding to the dummy housing (13). The dummy housing (13) and the opening (22) engage and create a stress to balance a stress created upon connecting the waiting-side connector (21) and the mating connector (12).

Abstract: An electrical connection box has upper and lower casings (10, 11) for accommodating circuitry. A surrounding wall (10a) of the upper casing (10) fits inside a surrounding wall (11a) of the lower casing (11). Engaging locking claws (10b, 11b) project from the outer surface of the surrounding wall (10a) of the upper casing (10) and from the inner surface of the surrounding wall (11a) of the lower casing (11). An upper wall of the upper casing (10) is inclined down from a center portion to three peripheral edges. A drainage path (13) is defined by a clearance between the surrounding walls (10a, 11a) of the upper and lower casings (10, 11). A bottom wall of the lower casing (11) has drainage holes (14) at the bottom end of the drainage path (13).

Abstract: Upper and lower casings (10, 11) have the surrounding walls coupled together. A bolt (B) is mounted beforehand in the casings (10, 11), and projects through a bolt hole (11c) in the lower casing (11) to fix the casings (10, 11) to a holder (20). A first bush (15) is fixed in the lower casing (11) and a second bush (16) is interlocked with an outer circumferential surface of the first bush (15). The bolt (B) passes through the bushes (15, 16) so that a lower surface of the bolt head (Ba) engages the upper end surface of the first bush (15). On the other hand, an inward-projection is formed on an upper part of the second bush (16), and contacts the upper surface of the bolt head (Ba). Thus, the bolt head (Ba) is held rotatably between the upper end surface of the first bush (15) and the inward-projection.
