Abstract: A lock lever structure includes a shaft; a cam attached to the shaft to fit a different-shaped portion of the shaft to prevent rotation of the cam in a circumferential direction of the shaft, the different-shaped portion having a different shape in cross section from a round portion of the shaft; a lever having an inner hollow cylindrical portion larger than an outline of the shaft and attached to the shaft to be rotatable in the circumferential direction of the shaft; a spring attached to the shaft to press the cam and the lever in an axial direction of the shaft; and a retainer attached to the shaft to retain the spring, the cam, and the lever to the shaft. The cam has at least two valley portions. The lever has a contact portion to contact the cam. The contact portion has a base shape.

Abstract: A holding structure for holding a microphone includes a chassis configured to be separated into at least a first chassis and a second chassis; an elastic member formed of an elastic material, the elastic member including a holding unit configured to hold the microphone and an attachment portion provided in a periphery of the holding unit; and a retention member configured to retain the attachment portion at a predetermined position of the first chassis. The retention member is fixed to the first chassis by the second chassis in a state where the second chassis is attached to the first chassis.

Abstract: Disclosed is a communication apparatus including an image input unit that includes an image input member that inputs an image of an object and a retaining member that retains the image input member at its one edge; an enclosure to which a concave portion is formed at its one side surface; a uniaxial hinge device that includes a first hinge member and a second hinge member rotatably connected with each other and capable of rotating around a first axial line with respect to each other, the first hinge member being connected to the enclosure and the second hinge member being connected to the other edge of the retaining member. The image input unit is rotated via the uniaxial hinge device around the first axial line with respect to the enclosure between a housing position and a protruding position.

Abstract: A compact, high-torque electric motor in which one motor element (either the stator or rotor) has magnetic poles whose effective magnetic width is substantially equal and which span equal center angles. The second motor element has a plurality of armature groups, each of which occupies a phase sector of the motor element formed by dividing the total periphery by a natural number. All of the armatures within an armature group are connected electrically in series and excited with a current of one phase (either an alternating current phase or an equivalent phase generated by commutator action). Within on pole group the poles may have equal widths or different widths.
