The upper lateral members 7a, 7b are downwardly sloped toward the center, and at the ends of the slope, clearance parts 10a, 10b which are communicated with the partitioned chambers 9a, 9b are formed, and the lower lateral members 8a, 8b are downwardly sloped in the direction going away from the center. Further, in the upper part of the longitudinal member 6c not connected with the upper lateral members 7a, 7b, a tubular air passage 13 is formed. And by connecting the water- collecting drainage pipes to each other, or by connecting this water-collecting drainage pipe with a drainage pipe of the other shape via pipe couplings, a water-collecting drainage device is formed. Thus, the reduction in weight can be achieved and the durability can be increased.

Title: Detector for partial discharge
Inventor: TAKAHASHI HIDEKI
IPC: G01R31/12
Filed: 1979-12-14
Abstract: PURPOSE: To easily separate a partial discharge signal from outside noises through measurement of a positive-polarity signal by employing a subtracting circuit composed of three wide-band transformers as a means for preventing the generation of output voltage by the detector due to the outside noises.  
     CONSTITUTION: Electrification current of diodes D 1 WD 4  flows through resistances 1W4 respectively and the terminal voltage thereof is detected. The terminal voltage of the resistances 1 and 2 excites the primary winding with neutral point of the wide-band transformer 5 to generate the full-wave rectification waveform or minute voltage of a loop current in the output of the secondary winding. The terminal voltage of the resistances 3 and 4 excites the primary winding with neutral point of the wide-band transformer 6 to generate the full-wave rectification waveform or minute voltage of the loop current in the output of the secondary winding. Thus, in the secondary winding of the transformer 7 is generated a voltage resulted from subtraction of the output voltage of the secondary winding of the transformers 5 and 6. By discriminating the polarity of this output voltage, the partial discharge signal can be detected through separation.

CONSTITUTION:Inverse electromotive forces induced in three-phase stator windings 11, 12, 13 and the selective signal outputted by a selective signal generating means 6 are inputted to a means 1 for sensing inverse electromotive forces. The means 1 for sensing inverse electromotive forces senses the zero-crossing points of the three- phase inverse electromotive forces according to the selective signal outputted by the selective signal generating means 6, and the zero-crossing points are converted into a pulse train m. The pulse train m represents the zero-crossing points of the three-phase inverse electromotive forces. The pulse train m outputted by the means 1 for sensing inverse electromotive forces is inputted to a logical pulse generating means 2 and a pulse delaying means 3.

Title: Plate type mfb speaker
Inventor: KOIZUMI AKIO
IPC: H04R3/00
Filed: 1978-12-29
Abstract: PURPOSE:To make it possible to improve considerably the characteristic of a speaker by controlling vibration of a diaphragm on a basis of capacity change of a capacitor formed between the conductive layer and the conductive material on the back face of the diaphragm. CONSTITUTION:Skin layer 6c and conductive material 13 on the back face of diaphragm 6 are so formed that they may be opposite to each other in parallel throughout the surface of diaphragm 6. Consequently, even if split vibration is generated in any position of diaphragm 6 when diaphragm 6 is vibrating, the capacity of the capacitor formed between the skin layer 6c and conductive material 13 is always changed. By detection of this capacity change, split vibration generated in any position of diaphragm 6 can be detected accurately, and motion feedback control can be performed accurately. Thus, distortion can be prevented from being generated in the characteristic of the speaker to improve considerably the characteristic of the speaker.
