Patent IT-973872-B (IT)
IPC: H01G7/02
Filed: 1972-12-04
Granted: 1974-06-10
Abstract: An electret transducer in which the electret material is an inorganic insulator sheet with electric charges in it and is juxtaposed to an electrode, and either the sheet or the electrode is mechanically deformable to change the distance between the two, thereby changing the electric charge induced in the electrode by the charged electret sheet. In a preferred form, the electret material comprises a multilayer sheet of insulating materials. The method of forming the transducer includes at least the steps of vapor-depositing a thin layer of inorganic material on a substrate and subjecting the exposed surface of the insulating material to a source of electric charge for a time sufficient to implant charges in the insulating material. If the insulating material is to be deformable, it should be deposited on a thin layer of metal which, in turn, has been deposited on a thicker substrate. A spacer layer of metal is deposited on top of the charged insulating material. Thereafter, selected areas of the substrate and of the spacer layer are chemically removed to leave the thin metal layer and the charged insulating material free of support except around the periphery of such open area. The ability of the insulating material to accept and hold a charge may be improved by depositing the insulating material as two separate layers of different materials, one immediately on top of the other.

Inventor: CONNELL LAWRENCE EDWIN
IPC: H03K19/0185
Filed: 1989-07-07
Abstract: A low current CMOS translator arrangement is disclosed that utilizes a low current inverting stage (102), having a peak current requirement, fed by a constant current source (104) at a supply node (+V) that also has a capacitor (106) coupled to it. This low current inverter (102) is useful for a number of applications, including generating a sinusoidal signal when it is coupled to a crystal. When one or more are cascaded and coupled to a square wave input signal, the arrangement becomes a low current translator that level-shifts, or translates, the input signal having a first voltage range to a translated square wave output signal having a second voltage range. In another embodiment called a low current squaring translator, a squaring stage is coupled between the low current inverter and a low current translator that includes one or more inverting stage.s This arrangement is able to achieve an output signal that maintains a precise duty cycle with low noise at a very low current.

Abstract: Large amounts of various modified forms of Pseudomonas exotoxin are produced. At least one of the modified forms (pJH8) of the exotoxin exhibits low toxicity to human or mouse cells by itself but retains its enzymatic activity and makes a very active cell specific immunotoxin with very low nonspecific cytotoxicity. All the constructs with low cytotoxic activity will be useful as vaccines to produce the antibodies to treat pseudomonas sepsis. In addition, the protein encoded by domain I alone could be administered directly to patients to treat pseudomonas sepsis because that domain would block toxin binding to cells. Clones containing domain II and particularly clone pJH12 can be fused to other toxins which have low activity (such as ricin A chain or pokeweed antiviral protein) to increase their cell-killing activity without increasing their nonspecific binding to cells.
Patent PT-88604-B (PT)
IPC: G11B5/596
Filed: 1988-09-28
Abstract: A magnetic data storage system for use with a double sided disk in which a prerecorded pattern of opaque optical lines is used to define the tracks in which magnetic data is to be stored. A separate optical system including an illumination source and a photosensitive detector is provided on a read/write assembly for each side of the disk. Each detector is designed also to serve as a reference grating. The illumination source is designed to image the prerecorded pattern of optical lines on the reference grating as an indication of the alignment of the read/write head of the assembly and a desired data track and any misalignment of the head and track generates a servo signal. The detector uses four separate photocells interleaved in a prescribed fashion to form a quadrature detector that is adjustable to compensate for various non-uniformities. One form of illumination source uses a surface-emitting light emitting diode and optics for forming a multiple beam source.
