Patent JP-H05248395-A (JP)
Title: Axial fan
Inventor: NAKAMURA ISAMU
IPC: F04D29/66
Filed: 1992-03-10
Abstract: PURPOSE:To reduce the sound of swirls to enable silent operation of an axial fan at low noise level by disposing small blades between main blades on the outer peripheral surface of a hub. CONSTITUTION:An axial fan 1 comprises a plurality of main blades 3 disposed at a proper angle pitch on the outer peripheral surface of a tubular hub 2 and small blades 4 are disposed between the main blades 3. The distribution of radial wind speeds of the axial fan 1 is such that at the center portion the wind speed shows a tendency to increase outwards from the center point, as in the case of conventional axial fans; in an area outside it, a uniform distribution of wind speeds is available. This is presumably due to the action of the small blades 4 to straighten air flow; i.e., generation of swirls that may cause the sound of swirls is restrained at the trailing flow, reducing the sound of swirls. Therefore, with a normal rotating area of a high frequency region above 800Hz, silent operation of the axial fan at low noise level is made possible.

Title: Color picture tube
Inventor: OKADA HISASHI
IPC: H04N9/28
Filed: 1978-07-17
Abstract: PURPOSE: To enable omission of a magnet for purity and static convergence alignment of a color picture tube by providing a circular electrode of magnetizable magnetic material between an electron gun and the inner wall of the neck of the picture tube.  
     CONSTITUTION: A circular electrode 12 of magnetic material is provided, for example, between the third gric 6 3  of an electron gun 6 internally mounted in the neck 5 of a color picture tube and the inner wall of the neck 5. This electrode 12 is connected via a conductor 13 to the third grid 6 3 . When the electron beam spot is displaced in such a color picture tube, the electrode 12 is aligned as multi-polar magnet from the exterior of the neck 5 using a multi-polar magnetic field generator. When the electrode 12 is thus magnetized, it necessitates no purity and convergence alignment at the color picture tube aligning time and no alignment magnet. Since the potential in the vicinity of the neck is thus stabilized. it can improve the withstand voltage characteristics of the electron gun 6.

Filed: 1986-04-15
Abstract: PURPOSE:To improve the freedom of design of devices and to improve mass- productivity by opening a coupling window on a metal plate and sandwiching the metal plate between a circular waveguide and a square waveguide.

Title: Antiphase detector
Inventor: MATSUO ISAMU
IPC: G01R29/18
Filed: 1978-07-14
Abstract: PURPOSE: To perform definite antiphase detection by a simple constitution, by making a logical judgement by a rectangular wave corresponding to the half wave of a three-phase current obtained by a current transformer and a narrow-width pulse at the time of the rise of the rectangular wave.  
     CONSTITUTION: A three-phase current from current transformers 1 to 3 is converted into pulses with the width equivalent to the positive half-wave period by three- phase half-wave rectifier circuit 4 and waveform shaping circuits 5 to 7 before being inputted to AND gate circuits 13, 11 and 12. On the other hand, those circuits 11 to 13 are applied with pulses of narrow width generated by differentiating circuits 8 to 10 when pulses outputted from circuits 5 to 7 rise; at the time of a positive phase, none of circuits 11 to 13 generates an AND output while OR circuit 14 generates a low-level output and at the time of an antiphase, the output of circuit 14 is inverted to a high level. Therefore, the transformed current is waveform-shaped by an amplifier which is sufficiently saturated with a slight load, so that definite antiphase detection can be carried out by a simple constitution even at the time of low torque or a slight shift in phase.
