IPC: H04B10/40
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To correct the waveform distortion of a light signal due to the rise delay of the light signal with simple constitution by applying a variable comparison reference voltage to a buffer amplifier and adjusting the pulse width when an input signal having its signal waveform rise and fall slanted by using a filter circuit is shaped through the buffer amplifier. SOLUTION: The input signal is inputted to an input terminal 11A of a filter circuit 11 to obtain an output 11B whose digital signal waveform rise and fall are slanted, and the output is inputted to the uninverted input terminal 12A of a buffer amplifier circuit 12. The buffer amplifier circuit 12 outputs a reference voltage 12C which is internally compensated according to a driving power source, so the voltage divided by it through resistances R12 to R14 is inputted as the comparison reference voltage to the inverted input terminal 12B. The uninverted and inverted outputs 12D and 12E of the buffer amplifier 12 are inputted to the uninverted and inverted input terminals 13A and 13B of a light emitting element driving circuit 13 to drive a light emitting element 14.

Title: Particle detection and breakage in hydraulic system
Inventor: ARAN BII OOUEN

Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce electromagnetic disturbance radiation at the time of burning up particles in the field using an easily programmable small unit by discharging electric energy stored at a preset level upon detection of a particle (chip) while traversing a contactor. SOLUTION: When a particle is detected while traversing the electric contactors 38, 40 of an arbitrary chip detector 30a, short circuit state of that channel (circuit) is delivered from a differential amplifier 46 through a multiplexer 48 to a μP 28 in order to energize a variable voltage DC/DC converter 16 thus storing (charge) the electric energy in a capacitor bank 18 up to a burn up level corresponding to the circuit of detector 30a. When the electric energy reaches the level corresponding to the detector 30a, the μP 28 deenergizes the variable voltage DC/DC converter 16 and energizes a power switch 26 associated with the circuit of detector 30a. Consequently, the energy stored in the capacitor bank 18 is fed to the detector 30a and the contactors 38, 40 are short- circuited thus burning up and destroying the particle.
