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. Further, the first silicon substrate on which the device substrate is located is bonded to the second silicon substrate, so that the first rectangular groove opposes the third rectangular groove, forming a rectangular waveguide which includes the first rectangular groove and the third rectangular groove, and in which a received high frequency signal propagates and is incident on the frequency conversion device.

Silicon substrate apparatus and method of manufacturing the silicon substrate apparatus

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

Antenna apparatus

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.

Parallel displacement/inclination measuring apparatus and antenna system

A golf club having a head made of metallic material such as aluminum, stainless steel, titanium or the like is provided with a shaft sleeve made of non-metallic material such as fiber reinforced plastic, wood or the like is mounted on a tip end portion of a shaft or a shaft insertion portion of a head with which player's wrists, elbows, shoulders or the like would hardly be damaged, it is easy to enjoy an inherent performance of the shaft, to enhance a repulsive force by a kick back phenomenon to increase a hit distance of the ball.
