Abstract: A first rectangular groove having a rectangular cross section and a second rectangular groove substantially orthogonal to the first rectangular groove and having a rectangular cross section are formed in a first silicon substrate. A third rectangular groove located at a position facing the first rectangular groove and having a rectangular cross section is formed on a second silicon substrate. A device substrate including a frequency conversion device is provided in the second rectangular groove, so that the frequency conversion device is located where the first and second rectangular grooves are orthogonal to each other.

Abstract: An antenna apparatus detects a reflected light from a scattered light or from a reflector (40) mounted in an optical fiber (6,6a-6d), measures a strain generated in a primary reflecting mirror (1) and so on based on the scattered light or the reflected light, and calculates a reflector surface compensation data based on the strain of the primary reflecting mirror (1) and so on. An antenna driving section (11) is driven according to the reflector surface compensation data in order to compensate a direction of an antenna.

Abstract: A laser pointer and an image sensor are employed as one measuring system, and two measuring systems are arranged such that a laser beam is irradiated in the opposite direction. One laser pointer and one image sensor are arranged on the measuring reference portion, and also One laser pointer and one image sensor are arranged on the measured portion. The parallel displacement &Dgr;X and the inclination &thgr; of the measured portion are calculated separately based on measured results obtained by these two measuring systems.

Abstract: A golf club head includes a body having a front face which is adapted to engage a golf ball, the front face being disposed at an acute angle relative to vertical when a player addresses the ball by viewing the golf club head when the golf club head is in a position to engage the golf ball. The front face has an upper edge portion which is chamfered to form a chamfer face which is disposed at an obtuse angle relative to the front face. The chamfer face has an upper edge which defines the upper boundary of the head body while the front face has a lower edge which defines the lower boundary of the head body. The chamfer face and the front face are disposed such that when a player addresses the ball, the player perceives the plane extending between the upper and lower edges as the ball-engaging plane such that the player thereby perceives the loft angle to be greater than the actual loft angle, the actual loft angle being the acute angle of the front face relative to vertical when a player addresses the ball.
