Description

Lea (the meters | of their substance are growing, and this is in case of the case of sop, with additional time for a constructive pairing of the equipment of the T1va. Complicated repair of photoresistors and illuminators with a change in the order number of the harmony: mono dependence. After the rewiring of a nezadhadim additionalpolitivna YuSti.rO (in, ka light-optical paths.

The aim of the invention is to reduce the time spent on the setting of the device for multiplying electrical signals: By harmonic fusions of different colors | MONIC.

To do this, two curtains are introduced into the device; they are made in an IB form of semi-diodes, balls | fixed (on the axis of rotation from two sides, on the body and connected, equipped with a fi xator) (And two of the Oveterti bodies are placed on one curtain along the circumference at an angle | M l / 2, and optically reassembling the associated co-operative 1 transform | 1cie blocks - against the hedgehog of ideas |

FIG. 1 schematically shows the proposed device, general view; in FIG. 2- schematic diagram of one of the channels of conciliation; on fwg. 3 is a diagram (locations of preabrasive blocks on photoresistors with multiplication for harmonic dependencies with n 1 and 2, as well as for the corresponding | HC1HpO; 3: modulating cancer cores.

A device consisting of mechanical and electrical parts is considered on the example of a three-channel multiplication device, since the increase in the number of multiplication channels co: is straight only with an increase in the number of cells in the conversion units and with the addition of opaque patterns of continuous harmonics of geo .Meter 11cheoki similar profile.

The device contains a shaft / with a modulating disk 2 made of pro3 (cancer material (organic, organic glass) mounted on it), on which opaque templates 2i-22 are placed, two covers 3 4 4 with holes forming a cylindrical body, elements 2, 3 , 4 form a modular unit, two 5 l 6 pin hinges, made in vice half disks, hinged on the axis of rotation of the shaft / on both sides of the housing and connected to each other by a clip 7 with a latch 8, four conversion blocks 9, two of which placed on the flap 4, and two on shchtor.k 6, four light l 10, two of which are located on the cover 3, and the other two - on the curtain 5.

Opaque bars of a modulating disk 2 have profiles representing harmonic dependences of the harmonics of the required order; constructed in polar coordinates relative to initial circles whose radii are equal to the distance from the axis of rotation of the modulating disk 2 to the middle the photosensitive pad of the Kahadi photorespstor in the transforming unit, while all photoresistars are located along the circumference of the case of the IB device of one nloskie on the bottom, m and the same radial distance from this axis. The width of the opaque profiles is equal to the distance between the middle of the photosensitive areas of neighboring photoresistors; In black. The maximum value of the amplitudes of the harmonic functions in the optical coordinates is half the height of the photoresistor's light-sensitive area.

The electrical part of health (fig. 2) contains 2k (k is the number of multiplication channels) of photoresistive bridges 11 containing photoresistors 12 in active arms and resistors 13 in passive lines.

FIG. 3, a and b shows a view of the device from the side of the scissors 6. The view from the side of the scissors 5 is similar.

Depending on the order of the p, the photoresistors in the conversion units 9 are connected between C0 | battle as follows.

For odd harmonics, the first with the second, and the third with the fourth, with this. All the converting blocks 9 on the cover 4 and on the scraper 6 are mutually co-ordinate (Fig. 3a, the first position of the lock 8). For (I am the even Gar / Monique of the photoresist in the conversion units 9, the first is connected with the third IM, and the second with the fourth and the shutter 6 is shifted by an angle l / 4 (Fig. 3b, the second position of the lock 8.) Modulating disk 2 each time It is chosen with the corresponding opaque sha: blons. Due to the fact that the 5mb curtains are shifted according to, the angles of the light 10 at n 2 will be equal to l / 2.

Ra: the bot device and its settings are as follows.

Fixing the lighters 10 of the node with unchanged U / m on one side on the lid 3 and the curtain 5, and the corresponding optical converters 1 blocks 9 on the opposite side, optically connected, the optical systems and the rigid connection of the curtains 5 and 6 s are made many ro.KOHTaiKTH s m p er key on the phone.

Signals (i) - O.D. from som.factors (Fig. 2) are connected to the input diagonal m of each pair of photoresistive bridges. The second factor is the sine (sin na) t) and cosine (cos n & t) of the angle of rotation of the shaft / with a 1Modulating disk 2, which changes the light fluxes of photoresistors with the help of opaque bars and causes proportional izmaneni.i increments of their resistances.

Claims (2)

The photoresist bridges multiply the input voltage by the signal depending on the increment of the resistances of the active arms. As a result, on the output diagonal of the photoresistive bridges, which are the outputs of the device, we obtain the following output lines, proportional to U /, (t) sin pm / and Ui, (t) cos ni,) i. When changing the order of the harmonic dependence (scaling, processing and even), it is enough to change the modulating disk 2 with the corresponding iHenip03pai4Hbi; MH templates and by turning the shutters 5 and b by the angle / 4 relative to the Case to fix them with a lock 8. The device is provided with an automatic Kommutaschi photoresistors in the reflecting units 9 by means of a multi-switch. At the same time, the position of optoelectronic couples on the body and on the shutters 5, 6 is violated, and there is also no need to rewire them at angles and in the alignment of optical systems, which in turn leads to the elimination of the drawbacks inherent in the prototype. The developed multichannel device for multiplying electrical signals, and the harmonic dependences are intended for use in harmonic aerial equipment for studying nonstationary characteristics of aircraft models in wind tunnels using the method of forced oscillations. Reducing the setup time of a device to prepare it for multiplication with other harmonic pai6oTbi aerodynamic tubes without stopping in order to preserve the identity of the pairs of meters brings Essential Eco-Efficiency.
