Title: Flight control system
Inventor: UMIBE MASAHISA
IPC: G01S13/88
Filed: 1991-08-28
Abstract: PURPOSE:To prevent the deterioration of misdistance by a method wherein a guidance signal, obtained by a seeker, is added sequentially with the stored data of a data memory unit to cancell the change of the changing rate of the angle of line of sight due to the acceleration and/or deceleration of a missile itself and effect homing flight of the missile on a straight line substantially toward an estimated point of rendez-vous. CONSTITUTION:An operating device 14 produces guidance correcting data at a plurality of times for correcting the amount of change of the changing rate of the angle of line of sight, which is generated due to the acceleration and/or deceleration of a missile, previously from a target information and the flight characteristic information of the missile while supposing that the flying target T does not effect acceleration, deceleration, turning and the like, then, stores them into a data memory unit 21 loaded on the missile. After the missile is launched and homing is started, a guidance signal, obtained by a seeker 22, is added with the stored data of the data memory unit 21 sequentially by an adder 27. According to this method, the change of the rate of change of the angle of line of sight due to the acceleration and/or deceleration of the missile itself is cancelled to effect the homing flight of the missile on a straight line substantially toward an estimated point of rendez-vous whereby the deterioration of misdistance is prevented.

Abstract: PURPOSE:To obtain a device capable of detecting leakage of oil without fail by a construction wherein the ends of two optical fibers forming an optical joint are connected to each other in the state wherein a force separating them from each other is applied thereto, by fixing them with a substance which softens or melts when immersed in oil. CONSTITUTION:The ends on one side of two optical fibers 2 and 3 are made to contact with each other oppositely inside a hollow-cylindrical case with an oil inlet 4 formed therein, and simultaneously are fixed in the state in which a spring pressure is applied thereto in the direction perpendicular to the axial direction by a spring material 6, by filling up the case with a substance 7 which is softened or melted by an oil such as paraffin and elastomer. A device 1 thus prepared is disposed in a place where the oil is likely to leak out, and it is monitored at all times or any time whether or not a light applied to the other end of the fiber 2 appears at the other end of the fiber 3. When there is any leak of the oil, the substance 7 is melted or softened to separate the contact parts of said fibers from each other by the action of the spring 6 and thereby to intercept the light. In this way, the device enabling remote monitoring, making an explosion-proof device unnecessary and being free from an electromagnetic induction impediment is obtained.

Title: Portable semiconductor memory device
Inventor: MORI YOSHIHIDE
IPC: B42D15/10
Filed: 1990-08-18
Abstract: PURPOSE:To prevent the generation of the breakage of an element or the degeneration of data by arranging the metal piece directly connected to the circuit ground of a built-in substrate in close vicinity to an insulating layer and forming the part opposed to the metal piece as a low withstand voltage part lower than the other part of the insulating layer in electrostatic withstand voltage. CONSTITUTION:An electrode piece 8 is arranged in close vicinity to a metal panel 2 and the ground terminal of this circuit is connected to the earth terminal of a terminal machine. The part opposed to the electrode piece 8 for a negative electrode among the respective parts of an insulating layer 1.0 is formed as a low withstand voltage part 10a lower than that of the other part of the insulating layer 10 in electrostatic withstand voltage. When the noise due to high level electrostatic discharge is applied to the metal panel 2, a discharge current flows to the circuit ground terminal 4 from the metal panel 2 but a part low in insulating withstand voltage is selected from this discharge route to form a discharge route reaching the circuit ground terminal 4 from the metal panel 2, a low withstand voltage part 10a and the electrode piece 8 for the negative electrode. Since a discharge current flows to the circuit ground terminal through the shortest route, it is prevented that an element is broken or data is degenerated.

Title: Protective detection circuit for current type inverter
Inventor: METSUGI MASATAKE
IPC: H02M1/00
Filed: 1990-08-18
Abstract: PURPOSE:To realize reliable protective detection of individual switching element with an appropriate margin by detecting input and output voltages of a current type inverter, rectifying thus detected voltages, making the difference therebetween and canceling the load voltage part thereby detecting the ON voltage of the switching element. CONSTITUTION:A comparator 91 in an excessive element ON voltage judging element SH 9 is fed with a signal produced by subtracting the output voltage of an input voltage detector 6 from the output voltage of an output voltage detector 7 and then rectifying the difference. Consequently, the SH 9 extracts and detects only the ON voltages of the elements 41a, 41b and the like in an inverter 4. As a result, ON voltage of transistor increases abruptly from the vicinity of rated current Ic1 thus enabling overcurrent detection of individual element. Since the ON voltage Vce increases abruptly even if the base current Ib is insufficient to cause a current flow over the DC amplification factor of the transistor, abnormality including malfunction of base drive circuit can be detected.
