Title: Muffler
Inventor: BABA TAKANORI
IPC: F01N1/08
Filed: 1980-07-25
Abstract: PURPOSE: To restrain exhaust gas from being changed into white smoke in a muffler in which a final expansion chamber is communicated with the atmospheric air by means of a tail pipe by disposing a one-way valve for preventing exhaust gas from flowing reversely on the downstream side of a pipe which introduces exhaust gas to the final expansion chamber.  
     CONSTITUTION: Exhaust gas exhausted from an engine flows into a muffler through an exhaust pipe 26. In the muffler, the exhaust gas circulates in order a first expansion chamber 20, a pipe 30, a second expansion chamber 22, another pipe 32 and a final expansion chamber 24 so that it is alternately expanded and throttled to thus reduce variations of the pressure of the exhaust gas. Also, high frequency sound energy is effectively absorbed by an acoustic material 28 within the first expansion chamber 20. The exhaust gas thereafter passes the final expansion chamber 24 and then a tail pipe 34 and is exhausted into the atmospheric air. A one-way valve 42 is provided in an opening on the atmospheric side of the tail pipe 34 in order to prevent the atmospheric air of a low temperature from reversely flowing into the tail pipe 34 due to pulsations of the exhaust gas, thereby restraining the exhaust gas from changing into white smoke.

Title: Heat transfer tube
Inventor: IZUMI MASASHI
IPC: F28F1/40
Filed: 1985-05-15
Abstract: PURPOSE:To display heat transfer performance even upon inflow of steam having high dryness by a method wherein a plurality of fins, extending in parallel to the lengthwise direction along the axis of the tube, is provided on the inner surface of the tube so that the height of the fin is reduced gradually from the inlet port side of the tube toward the outlet port side thereof. CONSTITUTION:In case superheated steam having a high dryness flows into the heat transfer tube 1, much amount of latent heat of the superheated steam is transferred at the inlet port side of the tube to the outside of the tube and the dryness of the superheated steam is reduced suddenly since the heat transfer area in the tube is formed so as to be wider at the inlet port side of the tube. As a result, the superheated steam becomes saturated steam at a part near the inlet port of the heat transfer tube 1. The fins 2, 2...of the heat transfer tube 1 is formed in parallel to the lengthwise direction along the axis of the tube and are provided also with the guiding function of the flow of steam, therefore, the flow of steam is improved. On the other hand, the heights of the fins 2, 2...are formed so as to become lower gradually toward the outlet port side of the tube and the sectional area of the tube is widened gradually to reduce the resistance of the flow of steam, therefore, deterioration of the flow may be prevented and the performance of the heat transfer tube 1 may be displayed sufficiently.

Title: Dc-dc converter
Inventor: MATSUO HIROBUMI
IPC: H02M3/28
Filed: 1991-02-25
Abstract: PURPOSE:To avoide a mode in which a resonance capacitor is short-circuited by firing a second switching element connected in reverse parallel with a second diode upon extinction of a first switching element. CONSTITUTION:The DC-DC converter is different from a conventional one in that a switching element(Tr) 9 and a diode 6 are connected in reverse parallel. When a Tr 2 is fired at time To, primary winding current (IL1) increases. When the Tr 2 is extinguished at time T1 and the Tr 9 is fired, a capacitor 4 and a transformer 5 constitute a series resonance circuit and the IL1 vibrates sinusoidally to release the diode 6 thus feeding a negative secondary winding current (IL2). At time T2, the IL2 goes positive to feed a current to the diode 6 and conventional operation takes place after extinction of the Tr 9. Consequently, when the negative current IL2 is fed during the interval from time T1 to time T2, the peak value of IL1 required for obtaining the same output current IO increases but no short circuit area appears.
