Abstract: PURPOSE:To permit the protection of a ship and an attacking vessel from a threatening target by a method wherein attacking weapons on board the ship are shifted to a specialized attacking vessel, which is small-sized and having enough maneuvability, while the ship is unified to the attacking vessel systematically. CONSTITUTION:A weapon control unit 6 is shifted from a ship 2 to an attacking vessel 15 and the attacking vessel 15 is advanced previously in order to entrust attacking operation to the attacking vessel 15. When a radar 4 on a ship 2 is detected that a threatening target 1 is appeared, the ship 2 outputs immediately to the attacking vessel 15 an attacking command together with a remote/local operating command 13, showing whether the attacking judgement is entrusted to the attacking vessel 15 or not, then, attacking is applied on the threatening target 1 in an early period and the attacking vessel 15 is retreated. When threatening radio wave 21 from the threatening target 1 is monitored by a threatening radio wave receiver 19, tactics of applying an attack on the threatening target 1 automatically may be effected based on a knowledge collecting type data base 24 in order to protect the attacking vessel 15 itself from the attacking of the threatening target 1 against the attacking vessel 15. On the other hand, the bearing angle of a threatening axis is judged by a receiving unit 19 which is monitored the threatening radio wave 21 whereby the movement of the threatening target 1 may be caught correctly by a target tracking unit 26 and attacking may be applied on the target.

Title: Vertical thermomagnetic recording system
Inventor: TANAKA MOTOHARU
IPC: G11B11/105
Filed: 1981-05-12
Abstract: PURPOSE:To enable a recording with a size smaller than a heated minute part, by heating continuously a minute part of a recording medium to a Curie point or more and moving the part, magnetizing the part when the temperature is near the Curie point and keeping the magnetization when the temperature further drops. CONSTITUTION:An example of execution and an enlarged view of a point P are shown in a figure. A recording medium 13 moves toward the arrow in high speed. A thermal wire spot position is moved, and the spot part as shown in a circle (a) (heated to a compensation point or more) is moved by DELTAx after DELTAt second and comes to the position of a solid line circle (b). Thus, the hatched part (c) is decreased in the temperature. In this case, since the coercive force of the magnetic substance film is small, magnetization is made toward a coil 14 and when the temperature closes to a room temperature, since this coercive force is increased, the direction of magnetization at the hatched part (c) is not inverted even if the magnetic field of the coil 14 is inverted afterward.

Abstract: PURPOSE: To make it possible to use resources effectively and reduce the maintenance cost by using general cards, where PROMs are mounted, to constitute a digital comparison function.  
     CONSTITUTION: In case that a three-digit value of BCD counters 5 to 7 and "315" set to PROM 1 to 3 are compared with each other, output 1 of PROM 1 is outputted to output 10 only when value B of counters 5 to 7 and set value "315" of PROM 1 to 3 are equal to each other.

Abstract: PURPOSE:To improve the density of arsenic on the surface of a silicon substrate by a method wherein an arsenide compound is formed on the silicon oxide layer, on which arsenic is diffused, and on the interface of the silicon substrate at a specific temperature in inert gas atmosphere, the arsenic-silicon compound is oxidized at a specific temperature in an oxygen-containing atmosphere, and it is diffused on an arsenic-silicon substrate. CONSTITUTION:A silicon oxide layer of 100nm in thickness, having arsenic density of 1X10<21>atoms/cm<-3>, is deposited on a p-type silicon substrate by conducting an LPCVD method in which raw gas of Si (OC2H5)4 and As(OC2H5)4 is used. A heat-treatment is conducted thereon at 1000 deg.C for 90 minutes in an atmosphere of nitrogen only, and then they are heated at 1000 deg.C for 90 minutes in a nitrogen atmosphere containing 10% of oxygen. Subsequently, a silicon oxide film is removed using fluoric acid. The density of surface arsenic on the silicon substrate obtained is 3X10<20>atoms/cm<-3>, which is three times higher than the density obtained before using the atmosphere of nitrogen only.

Title: Nonvolatile analog memory
Inventor: YAMADA MAKOTO
IPC: H01L27/112
Filed: 1982-04-28
Abstract: PURPOSE:To obtain a nonvolatile analog memory of holding characteristic stable for a long time and sufficient output width by a method wherein the shift width of threshold voltage and beta of a memory element are set at a specific value, with the threshold voltage as the center immediately after manufacture. CONSTITUTION:A nonvolatile memory by an FET having a floating gate 4 and a control gate 6 can store the analog value, since the threshold voltage Vt varies according to the writing voltage Vd, and the drain current Id at the time of readout varies in response to Vt. Vt set by write is converged into the threshold value V0 immediately after manufacture by being left to stand, and the shift width is larger as Vt is larger. At the time of the voltage VG impressed on the control gate 6, Vt=(2Id/beta)<1/2>-VG, and the values of changes of the Vt shift width and the holding characteristic are approximately proportional. Sudden increase of drift is restrained by setting the Vt shift within a width of 1.83V, and decrease of output Id due to the reduction of widths is prevented by setting beta>100. By this constitution, a nonvolatile memory for storing analog values of holding characteristic stable for a long time and sufficient output width can be obtained.
