Title: Method of sealing-up ultrasonic wave
Inventor: NISHIDA SHIGETO
IPC: B29C65/08
Filed: 1979-02-19
Abstract: PURPOSE:To prevent the extreme fall of in the strength of ultrasonically sealed-up parts, by previously providing ultrasonic wave attenuation zones such as slopes, thin sections or the like on the overlapped edge parts of thermoplastic resin bands. CONSTITUTION:Slopes or thin sections are provided on the overlapped edge parts of bands 1a, 2a of thermoplastic resin such as polyester resin. The edge parts 3a of the bands 1a, 2a are then overlapped with each other so that ultrasonic wave attenuation zones are formed. An ultrasonic horn 4 is pressed on the overlapped edge parts to seal them up. Since the slopes or thin sections are provided on the edge parts 3a of the bands 1a, 2a, ultrasonic vibration does not concentrate to the edge parts. Therefore, local embrittlement or strength fall does not take place in the sealed-up parts.

Abstract: PURPOSE:To cancel the distortion in a stereophonic demodulating signal produced in a band pass filter of an intermediate frequency stage by providing a level adjusting circuit adjusting an output level of a multiplier circuit and a correcting means for correcting a subsignal by an output of the said level adjusting circuit. CONSTITUTION:An output signal S4 of a low-pass filter 4 and an output signal S5 of a low-pass filter 5 are multiplied at a multiplier circuit 9. In denoting the level ratio between input and output of the level adjusting circuit 10 as l (=8k), an output signal S10 of the level adjusting circuit 10 is expressed as S10 (1/4) lcos2pt. An output signal S10 of a subtraction circuit 11 is expressed as S11= S5-S10(1/2)cospt+(2k-l/4)cos2t. Thus, an outut signal S16 of an adder circuit 6 and an output signal S17 of a subtraction circuit 7 are expressed respectively as S16=S4+S11=cospt+(2k-l/4)cos2pt and S17=S4-S11=(2k-l/4)cos2pt. Since the adjustment is made as l=8k, the component of the cos2pt is zero and the presence of the 2nd harmonic distortion in the stereophonic demodulating signal is eliminated.
