Title: Multiple targets display processor
Inventor: KOHAMA SHIYUNICHI
IPC: G01S3/84
Filed: 1984-07-06
Abstract: PURPOSE:To elevate the multiple targets monitoring capacity of a sonar operator, by synthesizing data of multiple peak bearings into one data with a synthesization means to be outputted to one display. CONSTITUTION:A phase shaper 1 forms a directional peak from signals from a plurality of receivers and outputs arrival signals in terms of bearing. Then, a narrow band analyzer 2 calculates a power spectrum density in a short time for each of multiple frequencies from the arrival signals and outputs the intensity of signals at each frequency. Spectrum selection adders 31-3N selects characteristic frequency components for respective targets from the intensity of signals to totalizes them by bearings. Peak detectors 41-4N detect the bearings of peaks from the intensity of signals classified by the bearing. Signals of the respective detectors 41-4N are synthesized with a multiple targets display processor 7 and peak bearing of multiple targets are shown on a display 5.

Filed: 1984-07-05
Abstract: PURPOSE:To obtain a two-shaft turntable actuator which is excellent in responsiveness, by providing a condenser lens which converges laser lights at a position which is eccentric in the longitudinal direction against the center of the swingingly rotating movement of a rectangular turntable and becomes the node of the cut-of-plane resonance mode of the turntable. CONSTITUTION:A condenser lens 2 is positioned with, for example, its center at a position which is eccentric in the longitudinal direction against the center of the swingingly rotating movement of a rectangular turntable 10 and becomes the node of the out-of-plane resonance mode when the turntable 10 is driven upward and downward. The structural resonance mode of the turntable 10 when the turntable 10 is driven upward and downward is the lowest order resonance mode and becomes the out-of- plane vibration of the turntable coincident with the driven direction, but becomes antiresonance whose node passes through the center of the condenser lens 2. The structural resonance mode when the turntable 10 is swingingly rotated by means of a swinging totation driving mechanism is the lowest order resonance mode and becomes the in-plane vibration of the turntable 10 coincident with the driven direction. This vibration becomes a structural resonance frequency which is extremely higher than conventional torsional resonance frequencies.

Title: Bimorph-using focus adjuster and exposure controller
Inventor: TANAKA YOSHIHIRO
IPC: G03B3/00
Filed: 1986-06-16
Abstract: PURPOSE:To perform continuous focus adjustment with a simple constitution, by driving a photographing lens by utilizing a bimorph and controlling the voltage impressed across the bimorph by comparing the voltage with the voltage of an analog memory corresponding to the distance to an object. CONSTITUTION:When switches S1 and S2 are turned on and a comparator COMP outputs a high level, the output of an ANd circuit AN1 becomes a high level. As a result, a transistor (TR) Q1 is turned on and a base current is made to flow to another TR Q2, and thus, the TR Q2 is also turned on. When the TR Q2 is turned on, a voltage V2 which is boosted at a booster circuit 14 is impressed across a bimorph 4. As the voltage is impressed, electric charges are accumulated in a capacitor C2 and the voltage impressed across the bimorph 4 is boosted. When the voltage impressed across the bimorph 4 is boosted, the bimorph 4 is deformed and, at the same time, voltages divided by resistances R2 and R3 are also boosted. When the divided voltages become equal to the voltage of a capacitor C1 for memory, the output of a comparator circuit 6 is inverted and both the TRs Q1 and Q2 are turned off and power supply to the bimorph 4 is stopped.
