A zoom lens optical system includes a first optical group with a first lens having negative refraction, a second lens having positive refraction, and a light path changing unit to change the path of an incident light passing through the first lens to have light incident on the second lens. A second optical group is provided for varying magnification. The second optical group has a third lens having negative refraction, a fourth lens, and a fifth lens, wherein the fourth and fifth lenses are integrally connected and have negative refraction. A third optical group includes an iris diaphragm, a sixth lens having positive refraction, and a seventh lens having negative refraction. A fourth optical group is provided for focusing. The fourth optical group has an eighth lens and a ninth lens being integrally connected and both having positive refraction.

A method and apparatus for reducing a length of an antenna (402) involves an arrangement which includes an orthogonal antenna feed. An antenna includes a radiating element (404) with a length extending along an axis (418). The orthogonal feed arrangement permits recovery of a portion of the spatial volume comprising the antenna which is normally used for antenna matching circuitry (406). An end portion of the radiating element is chosen to be helically shaped and includes an RF feed gap. The RF feed gap is coupled to a matching network which includes elongated conductors (412). The matching circuitry is positioned so that the elongated conductors are adjacent to the first end portion and extend in a direction aligned with the axis, but orthogonal to the coils forming the helically shaped end portion.

In an image sensor in which a vertical length from a photoelectric conversion element to an uppermost micro-lens is minimal, and a method of manufacturing the same, the image sensor includes a substrate, a plurality of photoelectric conversion elements, and first to n-level (where n is an integer greater than or equal to 2) metal wires. In the substrate, a sensor region and a peripheral circuit region are defined. The plurality of photoelectric conversion elements are formed in or on the substrate within the sensor region. The first to n-level metal wires are sequentially formed on the substrate. The n-level metal wires within the sensor region are of a thickness that is less than the n-level metal wires within the peripheral circuit region.

Disclosed is a coin change which comprises a coin sort section 50 for sorting coins C discharged from an input hopper 21, and a coin storage section 60 for storing the coins C sorted by the coin sort section 50 on a coin type by type basis. The coin storage section 60 includes a plurality of coin storage grooves 63 provided respectively to the plural coin types and disposed parallel to each other. Each of the coin storage grooves has a width dimension slightly greater than the diameter of a corresponding one of the types of coins and extends approximately horizontally. The coin storage section 60 also includes a stacking belt 65 disposed along the base of each of the coin storage grooves to extend in the longitudinal direction of the coin storage grooves, and a stopper member disposed at the downstream end of each of the coin storage grooves and adapted to be moved between a coin-passing-enabling position of allowing one or more of the coins C to pass therethrough and a stack position preventing the passing of the coins C so as to allow the subsequent coins C to be stacked on each other

A flange 62 having motor mounting through holes 63 is provided on a motor 6, motor mounting holes 19 are provided on a base body 1, so that motor mounting screw 61 are passed through the motor mounting through hole 63 from a back surface 1b side so as to be screwed into the motor mounting holes 19 to fix the motor 6 to the base body 1. Housing mounting holes 83 are provided on a control housing 8, housing mounting through holes 17 are formed on the base body 1 so as to be offset from portions which are in abutment with the flange 62, so that housing mounting screws 81 are passed through the housing mounting through holes 17 from the back surface 1b side so as to be screwed into the housing mounting holes 83 to fix the control housing 8 to the base body 1.

The invention relates to a holographic optical waveguide device for three-dimensional dynamic display and augmented reality display equipment.
