Title: Metallic shell
Inventor: ASO YOSHIYUKI
IPC: F42B12/72
Filed: 1993-06-23
Abstract: PURPOSE:To obtain a metallic shell having a large destruction force by composing a shell core, a filler, a cylindrical jacket, etc., which are parts of the metallic shell, from a metal hydride that sufficiently occludes hydrogen or heavy hydrogen. CONSTITUTION:The outer surface of a shell core 1 composed of a metal hydride is covered with a heat-insulating material 2, so that the heat-insulating material 2 protects the shell core 1 from being heated by heat caused by shock waves during flight and generation of hydrogen from the shell core 1 is restrained until the shell hits on a target. But, metal hydride generates heat only when it occludes hydrogen or heavy hydrogen by an amount equal to the number of metal atoms or more. That is, when the shell core 1 made up of metal hydride hits on a target, the shell core 1 is rapidly heated by the impact of hitting and releases ten times or more heat energy than a conventional explosive does. Therefore, the small shell core 1 does a work similar to that done by an explosive having a high energy density, and a stronger destruction force can be obtained in the same destruction process due to an ordinary high explosive squash.

Title: Tone control circuit
Inventor: KUROSAKI TETSUYA
IPC: H04R3/04
Filed: 1987-06-17
Abstract: PURPOSE:To simplify circuit constitution, by using a common operational amplifier for tone control and loudness. CONSTITUTION:The output of the operational amplifier 44 performs the enhancement of a low tone area and the attenuation of a high tone area by operating the movable piece 57 of a variable resistor VR1, and performs the attenuation of the low tone area and the enhancement of the high tone area by operating the movable piece 59 of a variable resistor VR2. The impedance of an impedance change circuit 46 for the loudness changes depending on a frequency, and it goes to a low impedance at a low tone area side. Therefore, the output from the operational amplifier 44 is also voltage-divided by a resistor 7 and a variable resistor VR3, and also, is negative-fed back so that the low tone area side can be enhanced by the impedance change circuit 46. Thus, it is possible to simplify the circuit constitution by sharing the operational amplifier 44 for the tone control and the loudness.
