Title: Magnetic disk device
Inventor: SEGA MASAHIKO
IPC: G11B21/02
Filed: 1992-06-04
Abstract: PURPOSE:To prevent the deterioration of positioning accuracy of a head due to the vibration and impact of reaction force generated at the seek time of the head by providing an air spring for regulating a relative position relationship between a member on the side of a supporting mechanism in an actuator and a member surrounding the above member in a housing. CONSTITUTION:The head 19 is positioned by operating a spindle motor 18 to rotate disks 15 together with a spindle 16, conducting a current into a coil 24 of the actuator, moving a carriage 21 and controlling the current to flow into the coil 24. Upon seek of the head, the reaction force of its movement is given to the carriage 21. Vibration of a magnet carrying member 26 based on this reactive force is damped by an air spring 30, and hence vibration to be transmitted to the spindle 16 via the housing 11 is damped to prevent the oscillation of the spindle 16. Moreover, the damping force of the air spring 30 is increased by a diaphragm 38. The member 26 is carried by the housing 11 via a linear bearing 31 to minimize the vibration of the spindle.

Title: Fish finder for whitebait fishing
Inventor: MORI GENJI
IPC: G01S15/96
Filed: 1990-05-31
Abstract: PURPOSE:To perform detection with high resolution and inexpensively by modulating an echo signal in a broad band area, and transmitting it by a weak radio wave. CONSTITUTION:This fish finder is comprised of fish detectors at a slave ship side and a master ship side. The fish finder at the slave ship side transmits an ultrasonic pulse under the water by ultrasonic pulse transmission reception means 10-16, and receives echo from fish including whitebait. Synchronizing signals synchronized with the transmission timing of the ultrasonic pulse are generated at synchronizing signal generating means 25-29, and the echo signal is modulated by a frequency signal with at least band area >=several kHz with those signals at a broad and modulation means (frequency modulation circuit 20. Thence, the frequency signal is transmitted by the weak radio wave by radio transmission means 21, 23. The fish finder at the master ship side receives the radio wave, and demodulates the synchronizing signal and the echo signal, and confirms the echo signal as an image. Thus, distance resolution in the broad band area of the echo signal can be sufficiently heightened, and inexpensive constitution with a small amount of interference with another can be realized in the transmission of the weak radio wave.
