Filed: 1980-06-24
Abstract: PURPOSE: To efficiently perform a gravitational separation of nonmagnetic solid substance, by providing a separating zone spreading over the upper and lower sides of an opening of a V-shaped ditch, across which the flow direction is made to incline to the horizontal.  
     CONSTITUTION: Permanent magnets 1 of which under part is connected, are formed into a V-shaped magnets which are arranged symmetrically with respect to the plane 10 inclined by an angle θ from the vertical. A space C between the magnets 1 and its upper part, a space A above the magnets 1, and a space B above the magnets 1 and the outer side part, are all united into one body i.e. a tank 11, which is filled with magnetic fluid 2. When nonmagnetic solid substance is fed obliquely from an upper side into the fluid 2 of the A part in the tank 11, the nonmagnetic solid substance of low specific gravity moves across the upper part of the magnets 1 to the B part to settle into the bottom of the tank, and the solid substance of high specific gravity moves through a separating zone 4 into the magnetic fluid of the C part to settle and finally to pile up at the bottom of the tank. Thus the separation is performed efficiently depending on the difference in specific gravity of the solid substance.

Title: Picture recording method
Inventor: MURAKAMI SEIKI
IPC: H04N1/40
Filed: 1983-05-14
Abstract: PURPOSE:To attain excellent recording reproducing color by providing the priority on each image so as to prevent an image with other lower priority from being superimposed on a partial space, where at least one bit is standing, of a memory space storing the image having the highest priority. CONSTITUTION:When a control circuit 5 confirms that 1 bit is standing, an output of a data of a partial space corresponding to a graphic image is inhibited in the partial space. Conversely, when all bits of the character image in the partial space are ''0'', the output is not inhibited. The operation like this is repeated for each partial space of a prescribed area. The bit data is outputted as it is at an area where two images are not overlapped. The bit data in the partial space is not outputted at the part where the bit output value is not inhibited at the overlapped part. Thus, only the character pattern is recorded in the area where two images are overlapped on the recording paper, and each respective image pattern is recorded in other areas. As a result, a picture with good quality is recorded.

Abstract: PURPOSE:To perform the action of a motor and a transformer at the same time, by arranging the transformer windings of the arbitrary number of turns wound up in the same manner, in the same slots as those of the main windings of the stator of an AC motor. CONSTITUTION:To stator windings 1 and stator auxiliary-windings 2, single phase voltage is fed for start, and when a motor comes to given rotational frequency, then the auxiliary windings 2 are released by a switch 5 for operation. By the current of the stator windings 1 and the current of squirrel-cage rotor windings 3, an electromotive force is generated on transformer windings 4 which function as transformers. Accordingly, when the transformer windings 4 are inserted and wound up in the same slots as those of the main windings l in the same manner as shown in the figure, then voltage is generated between the terminals of the transformer windings 4 and can be used as the power source of another load.

Title: Air direction control device
Inventor: TERADA TAKASHI
IPC: B60H1/34
Filed: 1984-04-25
Abstract: PURPOSE:To let the whole air blow-off port be the effective portion of air flow passage even when fins are inclined at their maximum by a structure wherein the fins at both ends are made so as to bend themselves about their pivots by consisting fins of two rotatable wings. CONSTITUTION:For example, when a knob provided at the center of horizontal fins 20 is moved from its central position upwards, firstly the rear end of the central fin 20 is inclined so as to direct upward and consequently the front end of a drag link, to which the fin 20 is fixed, directs downwards. At this time, a pin 36 moves downwards in the hole 34 of an air direction control piece 33, resulting in pulling a pin 30 through a sliding member 29 to the rear side B. The extrusion of the pin 30 to the rear side B causes control links 27 and 28 to be pulled to the rear side B by the pin 30. Consequently, the front wings 25 of the fins at both ends of the horizontal fins 20 are respectively pushed to outer frame walls 2, resulting in controlling the air flow together with the rear wings 24, which are inclined in the same direction as the remaining fins 20 by means of a link 21. Accordingly, no blocking of flow passage develops and the whole incoming air is availably used and consequently air flow resistance becomes smaller.

Abstract: PURPOSE:To prevent insulator breakdown, deterioration of a displacement characteristic by multiplying the ratio of the thicknesses of a forward electric field applying side piezoelectric plate to a backward electric field applying side piezoelectric plate by specific times as large as the ratio of the electric field value of maximum electric field dependency of piezoelectric constant of the forward plate to coercive electric field value of the reverse plate. CONSTITUTION:In a piezoelectric bimorph element formed in a bimorph structure by boding two piezoelectric plates, piezoelectric d constants of a forward electric field applying side piezoelectric plate 1 and a backward electric field applying side piezoelectric plate 2 are made different, and the ratio of the thicknesses of the plate 1 to the plate 2 is set to 1.2-2.0 times as large as the ratio of the electric field value of maximum electric field dependency of piezoelectric d33 constant of the plate 1 to the coercive electric field value of the plate 2. That is, the thicknesses and materials of the plates 1, 2 are altered, a material having large piezoelectric d constant is used as the plate 1, and the electric field value is so applied that the electric field induction distortion becomes maximum. On the other hand, a piezoelectric material having large coercive electric field value is used as the plate 2 in which its available voltage is limited by the coercive electric field value to obtain a piezoelectric bimorph element having small insulator breakdown and high reliability.
