IPC: G01S7/28
Filed: 1986-09-04
Abstract: PURPOSE:To enhance target searching capacity necessary for the navigation of a ship, by setting a high energy emitting azimuth and a low energy emitting azimuth, and increasing and decreasing the intensity of a pulse signal by the azimuth of the antenna detected to control electromagnetic wave energy. CONSTITUTION:An azimuth setting part 6 sets a high energy emitting azimuth alphaand a low energy emitting azimuth beta. An azimuth comparing part 8 judges whether the azimuth of the antenna 2 detected by an azimuth detection transmitter 4 is the azimuth alpha or the azimuth beta. The judge result is sent to an amplification control part 10 and the mu-factor of an RF pulse amplifier 9 is controlled so as to be increased and decreased on the basis of whether the azimuth of the antenna 2 is the azimuth alpha or the azimuth beta. When the antenna 2 is within the azimuth alpha being an important monitor azimuth, the level of a pulse modulation signal with definite frequency is enhanced and said signal is supplied to the antenna 2 to bring an emitted electromagnetic wave to high energy. By this method, target searching capacity necessary for the navigation of a ship is enhanced and reliability can be enhanced.

Title: Disc fixing device and spindle motor including disc fixing device
Inventor: KO HAJIME
IPC: G11B17/028
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to save production cost by reducing parts and production processes by providing a configuration which fixes the disc when a pin member is positioned at a corner of an operating hole of a disc hub. SOLUTION: A long hole 21 is drilled in-side of a central portion of a rotor case of a spindle motor, The long hole 21 is formed diagonally to a diagonal line and its angle θ is within the range of 90 deg., its width k is smaller than the diameter of a pin and larger than the neck. Also, the pin is cylindrical and the neck interval is formed in alignment with the thickness of a rotor case, and thus it can be moved in the range of the length of a long hole when the pin is fitted in the long hole 21 and assembled. When the disc is rotated after lifting to an operating hole 3 of the disc hub, it always moved to the angle of the operating hole 3, a fixing force is developed when a further movement becomes impossible and the disk is fixed.  As a result, the disc fixing pin does not require mounting parts any more, so that the number of parts is reduced, production processes can be reduced and also production cost can be saved.
