Title: Multiblade blower impeller
Inventor: MIYAHARA SHINJIRO
IPC: F04D29/30
Filed: 1988-07-22
Abstract: PURPOSE:To improve the performance of the multiblade blower impeller in the title and reduce its noise by designating the number of blades, setting the total of blade outer surface areas larger than the surface area of the outer peripheral side surface of the impeller, and designating its diameter ratio. CONSTITUTION:The number Z of blades 5 is set as Z>=45, and the total of the outer surface areas of the blades 5 in a circular-arc shape is set larger than the surface area of the outer peripheral side surface of an impeller 1. At the same time, the ratio of the inside diameter D1 and the outside diameter D2 of the impeller 1 or its diameter ratio nu (D1/D2) is set as nu=0.88. As a result, high aerodynamic performance can be available and breakaways within a passage between the blades can be restrained during a high-speed operation. Then a blade load per blade can be reduced and the occurrence of noise can be restrained. And since the length of the chord of the blade is shortened and the passage between the blades are not extended, increase in frictional loss can be restrained.

Title: Liquid fuel combustion device
Inventor: HIKINO TADASHI
IPC: F23D11/00
Filed: 1982-10-19
Abstract: PURPOSE:To prevent the accumulation of a large amount of tar on the vaporization surface of a vaporization cylinder to thereby secure a stabilized combustion condition for a prolonged period of time by a method wherein the vaporization surface is roughened and oxidized by an anode oxidation process to form a porous film thereon and the temperature of the vaporization surface is made higher than the film boiling temperature of the liquid fuel. CONSTITUTION:A vaporization cylinder 11 is heated by a preheating sheath heater 12. When the temperature of the vaporization cylinder 11 rises up to a temperature at which the liquid fuel film-boils, a motor 7 is started and a cone 8, a shake-off plate 9 and an agitating vane 10 rotate. Then, simultaneously with the initiation of ventilation, a fuel pump operates to supply the liquid fuel over the cone 8 through a supply pipe 17 so that the liquid fuel becomes oil drops of 100mum in grain size as it runs against the shake-off plate 9 and the agitating vane 10 and scatters toward the vaporization surface 18. In this case, primary air is supplied into the vaporization cylinder 5 where the air is mixed with the vaporized fuel to produce a gas mixture which flows through a burner head 15 to make a combustion flame 16. The vaporization surface 18 of the vaporization cylinder 11 roughened to 50mum, treated by an anode oxidation process in a nitric acid bath to thereby form the porous film thereon. Thus, when the vaporization surface of such structure is heated continuously, the amount of tar accumulated on the surface reduces.

Title: Sound volume control circuit
Inventor: MIYATA KENJI
IPC: H04B1/10
Filed: 1985-08-20
Abstract: PURPOSE:To reduce the residual noises of the sound signals by receiving the AM/FM signal, detecting the sound signal through a receiving/wave detecting means, muting the output of a sound volume control means for output through a muting means when the degree of attenuation of the output of the sound volume control means is maximum, and outputting the result. CONSTITUTION:An electronic control type sound volume 3 controls the sound volume of the sound signal by the volume data D1-DN and therefore can know easily the degree of attenuation of the sound volume. Thus, the characteristics of the volume 3 are utilized by muting the sound signal when the volume 3 is turned down to its minimum level. Thus, the residual noises are reduced. In other words, the sound signal given from the volume 3 is applied to muting circuit 4 and the muting signal is delivered from an output circuit 14. As a result, the sound signal is muted and therefore attenuated less. Then, this sound signal is applied to a power amplifier 5. Thus, it is possible to reduce the residual noises of the sound signal when the volume 3 is turned down to its minimum level.

CONSTITUTION:A main signal 15 and equalizing signals 13-14, 16-17 are obtained through a delay line or LPFs 5, 6, and attenuators 7-10 from an input signal 12. In this case, the delay time of delay lines 2, 3 and the attenuation quantity of the attenuators 8, 9 are set so as to decrease the half value width of the amplitude, when waveforms of the equalizing signals 14, 16 have been subtracted from the main signal 15. On the other hand, the cut-off frequency and the delay time of the LPFs 5, 6 and the attenuation quantity of the attenuators 7, 10 are set so that a negative peak of the main signal 15 can be eliminated, when waveforms of the equalizing signals 13, 17 have been added to the main signal 15. In this state, by an adding circuit 11, the equalizing signals 13, 17 are added to the main signal 15, and the equalizing signals 14, 16 are subtracted, and an output signal 18 is obtained. In such a way, an isolated reproducing wave having no negative peak, which has been slimmed is obtained, and the read-out error rate is reduced.
