Title: Method and device for radar control
Inventor: KUMAZAKI MEGUMI
IPC: G01S13/10
Filed: 1988-08-22
Abstract: PURPOSE:To prevent the reception state of received pulse from deteriorating by outputting sent pulses without overlapping received pulses and minimizing the difference in pulse width between two successive sent pulses. CONSTITUTION:The sent pulses 6 outputted by a transmitter 3 are radiated by an antenna 2 to strike a target 1 and received by the antenna 2 as received pulses 7, and those received pulses are inputted to a receiver 4. A pulse width controller 11 calculates such sent pulse width 8 that the pulse 6 which is received last does not overlap with the received pulse. The controller 11 outputs a switching signal with the pulse width 8 to the transmitter 3, receiver 4, and memory 11. The transmitter 3 switches the pulse width 8. Then the pulses 6 and 7 are prevented from overlapping with each other. Consequently, the reception state of the pulses 7 is prevented from becoming inferior.

Title: Echo cancellor and echo cancelling method
Inventor: GEERII UEIN ERUKO
IPC: H04B3/23
Filed: 1990-08-07
Abstract: PURPOSE: To attain convergence on a correct impulse response at a sufficient speed by dynamically assigning a real time to plural generalized adaptive filters related with plural sub-bands in a sub-band echo chancellor for establishing fast overall convergence. CONSTITUTION: A real time distributor 109 responds to parameters α1 -αn for distributing a valid real time to generalized adaptive filters from 107-1 to 107-N, that is, sub-bands. This real time distribution is expressed by the number of, so called, real time blocks(RTB) to be distributed to the sub-bands, that is, the number (p)1 -(p)n of the superimposition and latest ratios of the generalized adaptive filters 107-1 to 107-N. Thus, the signals (p)1 -(p)n are transmitted from the real time distributor 109 to the generalized adaptive filters 107-1 to 107-N. Thus, convergence on a correct impulse response can be accelerated by an echo chancellor having an especially long impulse response.

IPC: G11B5/02
Filed: 1983-11-05
Abstract: PURPOSE:To record information at a good S/N ratio with good recording efficiency by heating selectively a recording medium made of amorphous magnetic alloy in specific composition selectively with a light beam, and inverting a magnetization direction at compensation temperatures and recoding the information. CONSTITUTION:A film 2 having an easy magnetization axis vertically is formed on the film surface of 4-dimensional amorphous magentic alloy GdTbFeCo4 with a 65-80atom% total atom ratio of Fe and Cd on a substrate 1. When this recording medium is irradiated with the recording beam 5, the temperature rises and the magetism changes in direction at compensation temperatures. The coercive force of the recording medium increases temporarily and abruptly with the temperature and then decreases after the magnetism is inverted. The inverted magnetism is further inverted again with an external magnetic field 4 larger than the current coercive force to face in the same direction with the ambience. When the recording beam passes on the surface and the temperature drops, the magnetism at the irradiated part 6 is further inverted to perform recording 7. Thus, information is recorded at the good S/N ratio with efficiency.

Title: Casting method of billet for hot extrusion by ni alloy
Inventor: TAMURA MANABU
IPC: B22D27/04
Filed: 1984-10-05
Abstract: PURPOSE:To obtain a billet from which a seamless steel pipe can be produced by direct hot extrusion without the generation of flaws by specifying the plastic anisotropy of the billet in the stage of casting the billet for hot extrusion from the melt of an Ni alloy. CONSTITUTION:The flaws are generated in the casting billet of the Ni alloy and the billet is not workable if said billet is subjected to direct hot extrusion. The cause for the generation of the flaws lies in the ununiformity in the solidi fied structure of the surface layer part of the billet and the factor to affect said ununiformity includes the solidifying temp. and solidifying speed of the ingot, the size of the crystal grains thereof and the shape of a casting mold. Plastic anisotropy is thereupon used as the parameter to affect the above- mentioned ununiformity. The parameter is determined by drawing a rectangular strip-shaped test piece of whcih the width, depth and length are respectively 5, 2, 30 mm in the longitudinal direction of the billet from the surface of the billet and applying 30% tensile strain thereto at a room temp. and determining the parameter by the equation. The solidified structure of the surface layer is controlled under the cooling conditions in the stage of casting so that the plastic anisotropy attains >=0.85.
