IPC: G02B26/10
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an optical operation device and optical path interval detecting device for accurately aligning a focus and an optical path. SOLUTION: Laser beams emitted by light sources 1A and 1B are reflected by collimator lenses 3A and 3B and further refracted by a half-mirror in one direction. A polygon scanner 7 makes fast scans with the laser beams. A horizontal-scanning-direction detecting element 11 has a slit 13 formed at right angles to a scanning direction. Each time two laser beams shifting in position in the scanning direction (horizontal scanning direction) pass through the slit 13, two waveform-shaped pulses are outputted from a converter. to is judged from the interval between the pulses how much the two laser beams shift in position in the scanning direction and on the basis of the deviation, a fine driving actuator 21A and a fine driving actuator 21B are driven.

Title: Crystal oscillation circuit for liquid sensor
Inventor: UENO YOSHIFUSA
IPC: H03B5/32
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To allow a negative resistor for a crystal oscillation circuit to be set at a sufficiently large value and to ensure stable oscillation in a liquid by using an odd number of amplifiers and a feedback circuit including a liquid crystal sensor. SOLUTION: When a crystal resonator in an oscillation circuit is used as a liquid sensor, the resonator is soaked in a liquid and changes in frequency are measured under each condition. In a liquid, effective resistance of the crystal resonator is about >=20 times as much as that measured in the air. Thereby, stable oscillation is difficult to be attained in the oscillation circuit. Thus, in order to improve amplification ratio of an amplifier, an odd number of amplifiers are connected in series to secure sufficiently large negative resistance of the oscillation circuit. Thus, stable frequency is supplied. An amplifier circuit uses three IC inverters and connected in series to obtain a liquid sensor having satisfactory oscillation intensity and also to attain negative resistance of the oscillation circuit up to about -3 kΩ to -5 kΩ.
