Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To reduce a leak current while impressing an inverted voltage at a specified temperature and a duration after a nickel film to be made a Schottky electrode being applied. SOLUTION: A lightly doped n epitaxial layer 3 is laminated on a heavily doped n+ substrate 4. A nicked film is evaporated by a sputtering on the surface (silicon surface) of the n epitaxial layer 3. After forming the nickel film patterning by photolithography is made to make a Schottky electrode 1. Succeedingly heat processing for the Schottky electrode 1 is made by a vacuum annealing hearth and so on. Processing conditions are set as temperature of 200±50 deg.C or 600±50 deg.C and duration of 5 to 30 minutes. Heat processing atmosphere may be in vacuum or in inactive gas (Ar or so on). Accordingly an inverted direction leak current can be reduced without loosing a forward property by the heat processing at near 20 deg.C or 600 deg.C after the nickel film being applied.

Title: Analog optical communication system
Inventor: HAYASHIDA FUJIO
IPC: H04B10/54
Filed: 1980-03-26
Abstract: PURPOSE:To reduce the distortion of modulated light by interposing a mode mixer between a light emitting element and optical fiber. CONSTITUTION:An electric analog signal inputted to input terminal 5 of light transmitter 1 drives LED6 for direct intensity modulation. Modulated light from LED6 is led to optical fiber 3 via mode mixer 2 and then converted by photodetector 7 in light receiver 4 into an electric signal, which is amplified to a proper level and then outputted as an analog signal to output terminal 8. Said mode mixer 2 nearly uniforms mode distribution in optical fiber 3 varying with the driving current of LED6 to reduce the current dependency, thereby sending the signal to fiber 3. Consequently, even if a loss of mode dependency is generated by fiber 3, the modulated light never distorts in itself, so that the system with good linearity can e constituted.

Title: Vibrating gyroscope

IPC: G01C19/56
Filed: 1989-02-18
Abstract: PURPOSE:To detect the angular speeds in two directions by providing a cross-shaped vibrator wherein four vibrating pieces are connected in a cross shape in an x-y plane as a unitary body. CONSTITUTION:In a vibrator 1, four vibrating pieces 2 are connected in a cross shape in an x-y plane. When an AC voltage is applied to a driving piezoelectric element 5 of each vibrating piece 2, a pair of the vibrating pieces 2 facing the direction of the (y) axis are excited in the same phase in the direction of the (z) axis. A pair of the vibrating pieces 2 facing the direction of the (x) axis are excited in the reverse phase with respect to a pair of the vibrating pieces 2 facing the direction of the (y) axis. Therefore, the driving force acting on a pair of the vibrating pieces 3 facing the direction of the (x) axis can be balanced with the driving force acting on another pair of the vibrating pieces 3 facing the direction of the (y) axis. Thus the vibrations on the driving sides can be balanced. When an angular speed around the (y) axis is applied to the vibrator 1, Colioris force in the direction of the (x) axis is generated in a pair of the vibrating pieces 2 in the direction of the (y) axis. Vertical plates 4a of a vibration detecting part 4 are vibrated in the direction (x). Detecting piezoelectric elements 6 of the vertical plates 4a detect the vibrations. Thus the Colioris force is detected, and the angular speed around the (y) axis can be detected.

Abstract: PURPOSE:To suppress the effect of a reflected light with simple constitution by detecting its own pilot signal included in an output signal of a photodetector and feeding back the amplitude and phase as an amplification factor and a phase shift of an amplifier and a phase shifter. CONSTITUTION:A pilot signal of its own station mixed by reflection is detected from an output signal of a photodetector 17 and the amplification factor of an amplifier 20 is adjusted by the amplitude of the pilot signal of its own station and a phase shift of a phase shifter 21 is adjusted at nearly 180 deg. by the phase of the pilot signal of its own station. Thus, the amplitude and phase of the signal inputted to a light emitting element 14 are adjusted and the resulting signal is superimposed on an output signal of the photodetector 17 and the feedback loop relating to the amplitude and the phase of the pilot signal of its own station is formed. Then the feedback loop is formed to decrease the amplitude of the pilot signal detected. Thus, the reflected light of the optical signal is effectively eliminated with simple circuit.
