IPC: C23G1/00
Filed: 1985-08-02
Abstract: PURPOSE:To prolong the endurance life of a stainless steel drum by mechanically spraying an HNO3-HF soln. on the parts of the drum damaged by burning during deposition so as to form a passivated layer on the whole inner surface of the drum as well as to simply dissolve and remove the damaged parts. CONSTITUTION:When a stainless steel drum is manufactured, gaps in the joints between the top and body plates and between the body and bottom plates are sealed by deposition. At this time, parts damaged by burning are produced. The parts change the property of chemicals filled into the drum. HNO3 is mixed with HF in 3:1 ratio and diluted with three times as much water as the mixture. The resulting soln. is mechanically sprayed on the damaged parts to passivate the inner surface of the drum as well as to remove the damaged parts. The durability of the drum is improved by the passivation. Thus, the endurance life of the drum is prolonged by said simple operation.

Title: Demodulating circuit of am stereo signal
Inventor: IWASAKI HIDEKI
IPC: H04H40/36
Filed: 1979-12-28
Abstract: PURPOSE:To prevent a sudden S/N deterioration in a minute range of the input electric power in comparison with an envelope system, by demodulating the stereo signal by the synchronous wave detection system using no + or -pi/4 phase shifter. CONSTITUTION:The output of the VCO4 is applied to the synchronous phase wave detector 6 which detects the phase modulation component of the output of the limiter 2. On the other hand, the output sinwct of the VCO4 has a shift deflected by 90 deg. to the AM stereo signal es(t) and is thus shifted by 90 deg. by the phase shifter 7. Thus the signal of cosphi with a synchronous phase detection is obtained from the output of the detector 6. The signal cosphi is then applied to the subtractor circuit 8 to give a subtraction to the IF output es(t), and thus only the amplitude modulation signal component is delivered from the circuit 8. This signal is put into the synchronous detection circuits 9 and 10 to receive a synchronous detection by sinwct and coswct and then applied to the matrix circuit 11 for demodulation.

Title: Carburetor for use in internal-combustion engine
Inventor: II AKIRA
IPC: F02M11/00
Filed: 1981-10-30
Abstract: PURPOSE:To provide an air valve type two-stage actuating dual compound carburetor, capable of preventing the run-on of an engine, by designing the carburetor such that the opening of an air valve is restricted at a closed idling position or at an initial opening of a primary throttle valve. CONSTITUTION:At the time of idling operation of an engine, the opening of a primary throttle valve 11 is relatively small, while a secondary throttle valve 21 is fully closed. In this state, a first lever 42 is turned by a connecting rod 41 connected to a lever 40, so that an air valve 25 is forcibly opened to a certain angle via a second lever 43 by the closing force of the primary throttle valve 11. Under such circumstances, if ignition is stopped by turning off an engine key, fuel is not ejected from a secondary main nozzle 26 since the air valve 25 is opened and hence the negative pressure acted to the nozzle 26 is low, even though return of the secondary throttle valve 21 is not sufficient by some reason or other. Thus, it is enabled to prevent the run-on of the engine.
