Title: Explosion chamber provided with silencing construction
Inventor: ARAKI MASATOU
IPC: B01J3/08
Filed: 1978-05-31
Abstract: PURPOSE: To effectively reduce the sound of explosion, and to extend the life of the explosion chamber, by making the cover of the explosion chamber into the hollow double wall or the hollow multiwall construction, and by arranging the open ports at a distance in the inner wall, the outer wall, or the middle wall.  
     CONSTITUTION: When the explosives explode, the detonation pressure is transmitted, and according to circumstances, the sound wave is generated; the pressure collides against the inner wall 6 and is attenuated by the baffling effect, and then, enters the interwall space 11, where the pressure is transformed into the sound wave which propagates and collides against the outer wall 7 and is hereupon again attenuated by the baffling effect. On the other hand, the gas generated by explosion flows covering whole area of the inside of the inner wall 6, or the gas enters from the open port 10 at the skirt portion of the inner wall 6 into the interwall space 11, where the gas pressure or the sound pressure is reduced by the baffle plate 13, and at the same time, the sound is absorbed by the acoustical absorbent; after that, the gas pressure or the sound pressure is exhausted from the open port 12 of the outer wall into the outside of the space. Besides, if the explosion chamber is made into a hollow triple wall construction, the silencing effect is further improved. According to this mechanism, the long silencing cylinder becomes unnecessary, and also, the life of the explosion chamber is extended.

Abstract: PURPOSE:To simply obtain an electrodeposition paint film of a prescribed thickness by coating a body to be coated by electrodeposition to form an electrodeposition paint film and by applying thick electrodeposition paint to the part of the body to which the paint film hardly sticks before the paint film is baked. CONSTITUTION:A body to be coated is coated by electrodeposition to form an electrodeposition paint film. Before the paint film is baked, thick electrodeposition paint is applied to the part of the body to which the paint film hardly sticks or the requiring an electrodeposition paint film of a larger thickness. The concn. of the thick paint is higher than about 18-22wt.% concn. of electrodeposition paint used in an electrodeposition cell. The thick paint may be any of anionic and cationic paints but the thick paint and paint used to form the paint film on the body are preferably of the same kind. By using the thick paint, a paint film of a desired thickness is easily obtd. and dropping during the application can be prevented. The wet paint films are then baked. The resulting paint film has performance comparable to that of a conventional electrodeposition paint film and exhibits higher rust preventing capacity.

Abstract: PURPOSE:To decrease the integration time by using a rigger signal to drive a switch and allowing an integration type A/D converter to integrate a signal to be converted for a prescribed time symmetrical around a zero cross point of an AC component superimposed on the signal to be converted. CONSTITUTION:A trigger signal of a trigger circuit (TRG) is fed to a control logic CL and a switch S3 is driven on/off by a drive signal relating to the trigger signal outputted from the CL. The TRG circuit detects a zero cross point of the AC component superimposed on the signal Vi to be converted, the CL decides the on/off time of the switch S3 based on the trigger signal fed from the TRG circuit to apply a prescribed drive signal to the switch S3. Thus, the switch S3 is turned on only for a prescribed time (T/4+T/4=T/2) symmetrical around the zero cross point of the AC component superimposed on the signal Vi to be converted in this way.
