Abstract:
An actuator has a first yoke plate, a second yoke plate, magnets, coils, a haptic feel providing member, and a coil fixing member. The first yoke plate and the second yoke plate each assume a plate-like shape having a generally square outline, and are provided approximately parallel with each other. The magnets are fixed to that surface of the first yoke plate which is opposed to the second yoke plate. The coils are provided movably between the magnets and the second yoke and are fixed to the coil fixing member so as to form a unitary body together. Electromagnetic forces that are generated in magnetic fields of the magnets act on the coils, whereby the haptic feel providing member that is supported by the coil fixing member is moved.
Abstract:
An elongated vehicle member including a front portion having a first polygonal cross section with vertexes, a rear portion having a second polygonal cross section with less vertexes than the vertexes of the first polygonal cross section and connected to a vehicle body, and an intermediate portion connecting the front portion to the rear portion. The intermediate portion includes a transitional portion having a transitional surface for gradually changing a cross section from the first polygonal cross section to the second polygonal cross section. A reinforcement extends forward from the rear portion across the transitional surface to the front portion.
Abstract:
A cassette tape player has two reel bases which couple with the reels of a cassette tape located in the hold position of the tape player, a drive motor which drives the reel bases to rotate, a tape slack eliminating mechanism which rotates each reel base in its own tape winding direction, two pulse generators, each of which outputs pulse signals that depend on the rotational states of one of the reel bases, and a pulse width comparator which detects whether the pulse widths of the pulse signals from the pulse generators have exceeded a prescribed value. During the tape slack eliminating operation, if a width of the pulse signal from at least one of the pulse generators exceeds the prescribed value, the player terminates the tape slack eliminating operation and proceeds to another operational mode. The player thereby eliminates tape slack in the cassette irrespective of the tape position.

Abstract:
A developing device includes a first developing roller including a first transport member that transports magnetic developer by rotating while being close to a latent-image carrier rotating in one direction and a first magnet member, a second developing roller including a second transport member that transports the developer by rotating while being close to the latent-image carrier at a position on a downstream side of the first developing roller in the one direction, and a second magnet member, and a regulation member that regulates transport amounts of the developer distributed to the first and second developing rollers to required transport amounts, and opposes the developing rollers with predetermined distances therebetween. The first and second developing rollers are spaced from each other. The regulation member is movably supported in an area closer to the latent-image carrier than a closest position between the first and second developing rollers.
Abstract:
A developing device includes first and second developer carriers facing each other in a facing region, a regulating member that regulates a layer thickness of developer, and a separation member. The first and second developer carriers respectively include first and second magnetic members that are respectively magnetized with first and second facing magnetic poles having opposite polarities. The separation member separates the developer so that the developer is supplied toward the first and second developer carriers. The separation member is disposed such that distances between the separation member and the first and second developer carriers are the smallest in a region in which a magnitude of a combined magnetic field of the first and second magnetic poles locally decreases as compared with a case where at least one of the first and second developer carriers is independently disposed due to interaction between the first and second facing magnetic poles.
