Patent JP-S59112603-A (JP)
Title: Electromagnet device
Inventor: OKADA YOSHINOBU
IPC: H01H50/40
Filed: 1982-12-17
Abstract: PURPOSE:To provide excellent response property even if sectional area of an armature itself is small, by a method wherein an auxiliary yoke is connected to one end of a yoke, and magnetic flux of the armature is by-passed by the auxiliary yoke. CONSTITUTION:If voltage is applied to a coil 8, magnetomotive force is generated and flowing of magnetic flux X1, X2 is produced. X1; yoke 7   auxiliary yoke 9   free end 10c of armature 10   armature surface 7a, X2; yoke 7   leg 10d of armature 10   free end 10c of armature 10   armature surface 7a. Such magnetic flux produces attractive force at an air gap T between the free end 10c of the armature 10 and the armature surface 7a of the yoke, thereby the armature 10 is attracted to the armature surface 7a about the base end 10a as fulcrum. Since the armature 10 has the auxiliary yoke 9 in parallel, the magnetic flux is by-passed thereby sectional area of the armature 10 at intermediate part may be reduced. In this constitution, the electromagnet is improved in the working time and the working speed.

Title: Production of metal hydride
Inventor: INOUE KIYOSHI
IPC: C01B25/45
Filed: 1984-10-25
Abstract: PURPOSE:Electrolysis is carried out using a cathode made of a hydrogen-storing metal to allow the hydrogen generated on the surface of the cathode to react with the cathode itself to produce a metal hydride of high hydrogen storage density without need of pulverization of the hydrogen-storing metal and high-pressure equipment. CONSTITUTION:For example, waste water 3 containing organic substances is fed to the electrolysis tank 1 in which active sludge is previously stored or to which it is recycled and the organic substance is treated, e.g., decomposed under agitation with unit 4. The chimney 8 for recovering metal hydride 8 is perforated on its side wall so that large sizes of refuse may not pass through into the chimney 8. When a voltage is applied from the source unit 15 between the anode 5 and the cathode 7, the anions in the waste water is removed their electrons to generate bubbles and a part of the bubbles are consumed by the active sludge and the remainder is collected in the bubble collector 6. In the meantime, the cations in the waste water bond to the anode itself made of a hydrogen-storing metal such as LaN5H6 to form a metal hydride such as LaN5H6 on the cathode surface. The hydride usually peels off in the form of a powder and precipitates or the peeling-off is accelerated with ultrasonic vibration.

Title: Silicate slurry with high fluidity and suspension stability
Inventor: MIYAZAKI NAOMI
IPC: C01B33/40
Filed: 1984-10-25
Abstract: PURPOSE:A small amount of crosslinked polymer of a carboxyl type monomer is added to an aqueous slurry of a silicate to give the titled slurry which is easy to handle as a detergent or its starting material. CONSTITUTION:An aqueous slurry containing 30-50wt% (calculated as anhydride) of fine particles of silicates is combined with a crosslinked polymer of a carboxyl type monomer. The polymer means an electrolytes with a high- molecular chain which has carboxyl groups and is crosslinked in branched chains. Since the polymer becomes acidic, when dissolves in water, e.g., an aqueous slurry of a synthetic zeolite, which is high in alkalinity, may be added directly, or it is neutralized with an alkali such as sodium or potassium hydroxide or an amine, then added to the slurry. The amount of the polymer added depends upon the apparent viscosity of the desired aqueous slurry and particle size of the silicate salt, however, it is preferred to be mixed in an amount of 0.01-0.3wt%.

Title: Cutting of new roving in roving exchanger and apparatus therefor
Inventor: SAITO YUKIO
IPC: D01H15/00
Filed: 1992-08-21
Abstract: PURPOSE:To certainly prevent mis-suction in pick finding of the end of a new roving and to cut the new roving nipped by a roving-ending head to a length sufficient to end the roving without any hindrance. CONSTITUTION:After performing pick finding by sucking a new roving through a suction nozzle under a high suction pressure while rotating a full bobbin, the suction pressure of the suction nozzle is reduced. The suction nozzle is then moved down while sucking the new roving and the new roving is nipped by a roving-ending head between the full bobbin and the suction nozzle. The suction nozzle and the roving-ending head are relatively moved in the vertical direction and the new roving is cut by engaging the new roving with a roving cutting member set to the suction nozzle. The suction nozzle is connected through a suction pipe 18 to a cotton-collecting box 15. An opening 33 made in the cotton-collecting box 15 is opened and closed by a shutter 39 so as to change the intensity of the negative pressure applied to the suction nozzle.

Filed: 1990-08-24
Abstract: PURPOSE:To omit high precision height adjustments of a supply tape guide and a take-up tape guide and to reduce the number of parts and also to attain low cost by forming the whole shape of a slant pole into an approximately conical shape and using a guide base in common for a lower flange of the supply tape guide and the take-up guide respectively. CONSTITUTION:The shape of the slant pole 13 is a conical shape formed with gradually smaller diameters from the upper end to the lower end, while lower flanges of the supply tape guide 5 and the take-up tape guide 7, bosses and fixing screws are omitted. Then, deviation force downward in the widthwise direction of a magnetic tape 3 due to the conical shape of the slant pole 13 is substituted for pressing force downward in the widthwise direction of the magnetic tape 3 by upper flanges 5a and 7a. Then, a flange of the guide base 15 is acted in place of the lower flange of the supply tape guide 5 and the take-up tape guide 7 respectively, so that the magnetic tape 3 is prevented from flawing due to its fall. By this method, the number of parts of the supply tape guide and the take-up tape guide is reduced, and the high recision height adjustment is omitted.

Abstract: PURPOSE:To send all fish finder information at all times without missing a video image near sea bottom by providing a transmitter having a synchronizing signal generating means and a delay transmission wave timing signal generating means and a receiver provided with a reception means and a signal reproduction means to the telemeter. CONSTITUTION:A transmission wave timing signal (KP signal) delay circuit 7 provided to a transmitter 6 delays the KP signal for a time for a synchronizing signal and returns the delay KP signal of the same width of the original KP signal to a display control circuit 2. A synchronizing signal generating/control circuit 9 generates a synchronizing signal from the KP signal and controls the changeover to send the synchronizing signal and the video signal to a transmission section 10. A reception section 15 of a receiver 13 demodulates a reception signal and outputs the video signal to a display section 14 and a synchronization detection circuit 16 detects the synchronizing signal and generates a pulse signal with a prescribed width after the end of the synchronizing signal and outputs the pulse signal to the display section 14 as a pseudo KP signal. Thus, the signal just before the KP signal is not replaced into the synchronizing signal and a space time and the data by an observation time required after the KP signal is entirely sent.
