IPC: G02B26/02
Filed: 1985-02-26
Abstract: PURPOSE:To place the light receiving elements adjacent to one another to minimize the device size by using constitution in which the neighboring light receiving elements different in wavelength range and light emitting elements opposite thereto by the intermediary of through-holes emit light within the effective wavelength range. CONSTITUTION:The light receiving elements P1-P4 and the light emitting element L1-L4 are mounted opposite to one another by the intermediary of through-holes h of a rotating plate A on which the 4-bit code is formed. The elements P1 and P3 and the elements P2 and P4 have different wavelength ranges so that the elements L emit light within the effective wavelength range of the opposing light receiving elements P. The light from the light emitting element L1 arriving at the light receiving element P2 is not sensed by the element P2. The same applies to the remaining elements. Hence, the light from adjacent light emitting elements accidentally arriving at the neighboring elements do not affect the function so that the respective light receiving elements can be mounted adjacent to one another to minimize the size of the overall device.

Filed: 1993-02-26
Abstract: PURPOSE:To allow easy detection of pressure variation by detecting the oscillation frequency of an amplifier connected with a strip line to effect positive feedback oscillation through a thin film thereby obtaining a frequency output. CONSTITUTION:An amplifier 10 is connected with a strip line 6 and effects positive feedback oscillation. A frequency detector 11 is connected with the output terminal of the amplifier 10 and detects oscillation frequency.

A conductor formed on the diaphragm 3 has area variable depending on the pressure applied to the diaphragm 3. Since the resonance plate 5 has resonance frequency variable with the area of the conductor, pressure dependent resonance frequency can be obtained. Since displacement in the center of the diaphragm 3 is determined according to a specific formula and the resonance frequency varies in proportion to the square of the pressure, pressure variation representative of resonance frequency variation can be detected.
