Abstract: PURPOSE:To detect ultrafine particles, by a method wherein floating particles are irradiated with a part of a two-split laser beam to generate a scattered beam thereof while the other part thereof is combined with the scattered beam by a frequency deviation thereof and a beat signal detectable from the composite beam is detected. CONSTITUTION:A part of an emission beam from a laser 11 is transmitted through a beam splitter 12 and passes through a detection cell 3. The scattered beam within the cell 3 passes through lenses 5 and 6 and a slit 7 and then through a beam splitter 17 via a lens 16. On the other hand, light reflected with the splitter 12 is inputted into acoustooptical modulators 13 and 14 and the emission beam with the frequency deviated is reflected with a total reflecting mirror 15 to be incident into a splitter 17. A composite beam obtained from the splitter 17 comes into a silicon avalanche photodiode 18 and an output current thereof is counted by a counter 10 through an amplifier 19 and a waveform digitizer 20. This enables the checking of weak scattered beams due to ultrafine particles thereby allowing the detection of the ultrafine particles.

Abstract: PROBLEM TO BE SOLVED: To obtain a tide level follow-up sensor which can be disposed closely to the surface of the sea by providing a wire extending from the lower surface of a float through the first through the third pulleys to a rod and connected to the lower end thereof. SOLUTION: The upper end of a vertically extending pipe 2 is secured to the upper part of a platform 1 and a float 4a is disposed in the pipe 2 with a wire 5 being fixed to the lower surface thereof. The wire 5 takes a U-turn at pulley 6, and goes through 6a, 6b, and passes through the outside of a guide pipe 8 before being fixed to the lower end of a rod 7. The float 4a has a buoyancy for balancing the rod 7 at a predetermined draft and the length of wire 5 is set so that a sensor 9 is located at a predetermined depth under the water surface when the float 4a is at that draft. Water level in the pipe 2 is varied depending on the tide level but it is substantially insusceptible to the swell. Since the rod 7 connected with the wire 5 is also invariant, the sensor 9 can be disposed constantly at a predetermined position under the surface of the sea.

Abstract: PURPOSE: To accurately control a seek operation by holding a tracking operation at the time of starting the seek operation and turning off the tracking operation at the time of positioning a lens in a prescribed position. CONSTITUTION: When access of an optical head is instructed from a controller, a driver 10 is controlled via a D/A converter 11 by a CPU 8, and a linear motor 14 is driven to hold the tracking operation under the on-state. Subsequently, a lens position signal of a lens position detector 15 is fetched by the CPU 8, and when the objective lens is positioned in the prescribed position, tracking drive is turned off. The seek operation is kept in the waiting state until the objective lens of an optical system 2 is brought into the prescribed position, whereas control other than seek control, such as focus control is executed by the CPU 8 during this waiting time. Consequently, a track loss in the direction opposite to the moving direction is eliminated, and hence track counting is accurately performed.

Filed: 1991-07-26
Abstract: PURPOSE:To obtain a vibrator, wherein warping because of the change in temperature of atmosphere is hard to occur by molding metal material or ceramic material into an irregular shape so as to obtain the polygonal cylinder state. CONSTITUTION:A vibrator 10 is formed of metal material such as, e.g. elinvar and stainless steel, or ceramic material in a regular triangle cylinder state. Pizoelectric elements 12a, 12b and 12c are formed at the central parts of the outer surfaces of the vibrator 10 when the vibrator is used as the vibrating body of an angular-velocity sensor. The vibrator 10 is bent and vibrated in the orthogonal direction with respect to the surface, on which the piezoelectric element 12c is formed, by driving signal that is applied on the piezoelectric elements 12a, 12b or 12c. When the vibrator is turned under this state around the axial direction of the vibrator 10, Coriolis force acts, and the vibrating direction of the vibrator 10 is changed. At this time, the voltage corresponding to the applied rotary-angle velocity is generated in each of the piezoelectric elements 12a and 12b. Therefore, the rotary-angle velocity applied on the angular velocity sensor can be detected by measuring the difference between the voltages generated in the piezoelectric elements 12a and 12b.
