A retaining tool with rotational locating device includes a main frame and a locator. The main frame provides a first lock part at an end thereof. The locator rotationally inserts through the main frame next to the other end thereof. The locator further includes an adjustable unit and a locking unit attached to the adjustable unit. The locking unit has a second lock part at the lower section thereof corresponding to the first lock part. The lock parts engage with an object and the locking unit with the second lock part is capable of moving vertically in case of the adjustable unit being turned horizontally. The object is forced to keep contact other objects tightly or to release from contacting other objects.

The present invention is directed to a compact balun device that includes an unbalanced port and a set of balanced differential ports. A first set of coupled transmission line structures is coupled to the unbalanced port and one port of the set of balanced differential ports. The first set of coupled transmission line structures is characterized by at least one device parameter and a first length that is substantially equal to a quarter of a wavelength (λ). The wavelength (λ) corresponds to a first frequency. A second set of coupled transmission line structures is coupled to another port of the set of balanced differential ports. The second set of coupled transmission line structures is characterized by the at least one device parameter and a second length that is substantially equal to the quarter of a wavelength (λ). The wavelength (λ) corresponds to the first frequency. A plurality of interconnections couples the first set of coupled transmission line structures and the second set of coupled transmission line structures. The plurality of interconnections are configured such that the compact balun operates at a reduced operating frequency, the reduced operating frequency being selected from a range of frequencies by varying at least one device parameter. The range of frequencies is approximately between one-sixth of the first frequency and one-half the first frequency.

A storage bag that can maintain compactness, into which an object can be easily inserted and stored, and whose shape can be changed after the object is stored in the storage bag. A storage bag including a cylindrical body and a bottom at one end of the body, wherein the bottom closes one end of the body, the other open end of the body is formed as a storage opening, and the inside space of the storage bag is formed as a storage space capable of storing an object, and wherein the body is made of fabric in which fibers are woven in perpendicular directions, and the fiber directions A and B in the fabric are inclined with respect to the circumferential direction and the lengthwise direction of the body.

This invention provides an optical imaging lens assembly, in order from an object side toward an image side including: a first lens element with positive refractive power having a convex object-side surface, a second lens element with negative refractive power having a concave object-side surface and a concave image-side surface, a third lens element with positive refractive power having a concave object-side surface and a convex image-side surface, a fourth lens element with negative refractive power having a concave image-side surface, and the two surfaces being aspheric; wherein the optical imaging lens assembly further comprises an aperture stop disposed between an imaged object and the first lens element, and there are four lens elements with refractive power.

A cable holder is provided with an attachment portion to be attached to a strap retainer of a portable device, and a holder plate portion having a plurality of supporting projections. The attachment portion is provided with at least one claw to engage with the strap retainer. The claw elastically deforms for attaching / detaching the cable holder. A cable hole for inserting the cable is formed between two contiguous supporting projections. The cable is threaded in the cable hole between the supporting projections. With friction between the supporting projections and the cable, the cable is prevented from being unplugged.

A connector characterized in that it: is a connector that has a plurality of plate-shaped terminals that include openings able to enclose protruding terminals of the other half of the connector, and that mates with the other half of the connector. The openings comprise a wide portion, a narrow portion and a transitional portion that transitions from the wide portion to the narrow portion, and, in a top view, are provided with a first shape that is left-right asymmetric with respect to the centerline of the plate-shaped terminals, or a second shape whereby the first shape is inverted about the centerline. The plate-shaped terminals are arrayed lined up in the width direction of the connector, and arrayed such that the plate-shaped terminals comprising an opening having the first shape and the plate-shaped terminals comprising an opening having the second shape alternate.

A detection head includes a plurality of detection array portions that are arranged in a direction along which the head is relatively displaceable. Position signals indicating a position of the detection head are calculated from output signals output from the detection array portions. In order to combine the position signals with one another and determine the position of the detection head with respect to the scale, weighting according to a level of the output signal is performed on the position signal of each of the detection array portions, and the weighted position signals are averaged.
