Title: Radiation-sensitive semiconductor device
IPC: H01L31/05
Filed: 1968-11-13
Abstract: An array of solar cells, photo-resistors &c. 18 are arranged on a common flexible insulating support 10 provided with incisions defining tags 12a, 12b, 14a, which include portions of metallized regions 12, 14 of the support 10. Each element 18 is connected between adjacent metallized regions. As shown, each metallized portion 12 has a tag at each end, one of which, 12b, is folded back upon itself so as to receive the lower face of the element 18 soldered thereto. The upper face of the element 18 is soldered to the adjacent tag 14a of the next metallized region 14. A layer of adhesive 19 holds the element during the soldering process. In a modification, Fig. 10 (not shown), each metallized region (26) has a tag (30) associated with only one of its ends, and the lower face of the element (31) is soldered to a small metallized region (23) on the upper face of the support (20) electrically connected to the corresponding region (26) on the lower face by a metallized hole (29). The tag (30) is soldered to the upper face of the element as in the illustrated embodiment. The preferred material for the support 10, Fig. 7, is a polyimide resin. The metallization may be provided by vapour evaporation to entirely cover one or both faces of the support 10, followed by selective etching to restrict it to the desired regions. Cu or Ag or a multi-layer structure having Ag as the outer layer may be used. Metal sheets may alternatively be stuck to the support, e.g. using a resin which polymerizes in the cold. A solder comprising Pb, Sn and Sb is used to fix the elements to the metallized regions, the electrodes on the elements themselves being made of Ag.

Title: Dictionary-reading device
IPC: G03B21/11
Filed: 1968-11-29
Abstract: A micro-film reader comprises a film on which are recorded in orthogonal array the pages of a dictionary or the like as photographic images, an alphabetical key-board 11, and film driving means for shifting the film in X and Y directions to bring the image containing a selected word to a position for projection on to screen 41 when the first three letters of the word is spelled out on key-board 11. The film driving means may consist of a series of coaxially mounted masking discs (211, 212, 213), Fig. 7 (not shown) selectively rotatable on shaft (16) in response to pulses transmitted to stepping motors (13) by depression of key (1) once for each mask. Light from source (222) passes through the superposed masks on to an array 220 of photoconductive elements, the superposition of the masks identifying a particular element. Each of these elements corresponds in position to an image of the micro-film (3) and the signal produced by the light from lamp (222) actuates X and Y direction indexing motors which position film (3) for projection. Each mask (211, 212, 213) has twenty-six sections, each having transparent portions corresponding in position to those portions of film (3) having images for pages containing words with a letter in a particular position. Alternatively, the film driving means may comprise a programme sheet having transparent portions whose positions correspond to those of the film at which images have words with letters corresponding to those struck on the key-board, means for positioning the sheet in X and Y directions whereby light may be passed through a selected portion to illumine an array of photoconductive elements whereby the necessary pulses are provided for the indexing motors.
Patent ES-367192-A1 (ES)
Title: Blazed surface hologram
IPC: G03H1/18
Filed: 1969-05-13
Abstract: In a method of forming holographic images an object modulated beam of coherent radiation is directed at one face 26 of a photo-hardenable layer 28 and a reference beam of coherent radiation, in phase with the object beam, is directed at the other face 12 to create a standing wave interference pattern in and at the faces of said layer to create a corresponding change in and at the faces of said layer in resistance to a solvent to produce surface relief holographic recording. Preferably the vector direction of the reference beam is other than perpendicular to the photo-hardenable layer and forms an angle of between 90 degrees and 180 degrees with the direction vectors of the object beam. The two beams are collimated. After exposure the photo-hardenable layer is developed in a suitable solvent to form at least one blazed surface. A self-supporting layer will form two such surfaces and can then be split to give two holograms. The blazed surface may be coated with a reflective material e.g. aluminium, gold, silver, chromium. Desirably the minimum direct distance of the top of the riser portion of each step in the blazed surface above the tread portion is between 0À05 and 10 microns. The image is reconstituted in the usual way. If the photo-hardenable material is self-supporting the surface relief may be produced on both its faces, and the layer hologram split to give two separate holograms.

Patent ES-393602-A1 (ES)
Title: Shift register stage using insulated-gate field-effect transistors
IPC: G11C19/28
Filed: 1971-07-06
Abstract: An insulated-gate field-effect transistor (IGFET) shift register stage occupies less semiconductor chip area because a separate ground lead to the gate and drain electrodes of a pair of IGFET load devices is eliminated. This lead is eliminated by substituting therefor a connection from those devices to a first clock phase which controls conduction through that pair of load devices and through a pair of cross-coupling transistors. A second clock phase, which is out of phase with the first clock phase, controls conduction through both an input transistor of the stage and a third IGFET load device connected to an output terminal of the stage.

Patent ES-410494-A1 (ES)
Title: Regulator for pneumatic vibrator
IPC: B06B1/18
Filed: 1973-01-10
Abstract: A pneumatic vibrator of the type having a vibration-generating body that rolls within a casing and is powered by compressed air is provided with an automatic control valve that limits the vibration of the vibrator to a predetermined value, regardless of the load imposed upon the vibrator. A valve member interposed in the passage by which compressed air is delivered to the vibration-generating body is normally urged into an open position that provides normal operation of the vibrator. A regulating body rolls in a raceway, one surface of which is movable in association with the valve member. When the regulating body is subjected to acceleration beyond a given value, it shifts outwardly, relative to the axis of the raceway, thereby shifting the movable surface of the raceway and, in turn, the valve, to reduce the air flow.
