Title: Disc drive slider lifter using shape memory metals
Inventor: YAEGER JOHN R
IPC: G11B21/12
Filed: 1990-11-30
Abstract: ABSTRACT      A slider lifter arrangement is provided for conven-tional disc drive assemblies.  The slider lifter includes a wire support having a pair of wire support arms extending outward from a head positioning assembly adjacent opposite sides of a flexure arm that carries a slider.  A lifting wire is strung between the opposing wire support arms in the space between the flexure arm and the disc surface. The lifting wire is formed from a shape memory alloy having martensitic and austenitic phase conditions.   The wire is arranged to lift the flexure arm sufficiently to lift the slider off of the disc surface when the wire is in a first phase condition while allowing the slider to rest on the disc surface when the wire is in a second phase condition. The wire is selectively electrically heated to change its state from one phase condition to the other.   The wire support is preferably formed integrally with the flexure assembly.  The lifting wire is also preferably coated with an insulating material.

Title: Silo with a discharge means
Inventor: SCHWEDES JORG
IPC: B65G65/44
Filed: 1990-12-21
Abstract: Abstract of the Disclosure A silo has a device for discharging bulk material from the silo,  the bulk material being composed of  particles varying  in  size up to  a maximum diameter.  The silo comprises a floor having a plurality of discharge openings and a scraper movable over an entire upper surface of the floor. Each of the discharge openings is sufficiently large to  allow  passage  of  particles  of  the  maximum diameter when the particles move with respect to the floor but which is sufficiently small to allow the bulk material to form bridges over the openings when the  particles  are  stationary.    The  discharge openings are spaced apart from each other by a distance which precludes significant compaction of the bulk material by the scraper and which assures that a front edge of the scraper will always be disposed proximate at least one discharge opening. This  ensures  that  the  bulk  material  will  be constantly discharged from at  least one of the discharge openings when the scraper is moving over the  floor  so  that  new  material  is  constantly contacting the front surface of the scraper.

Abstract: A system for the automated transfer of data includes a means for transmitting a paper form by telephone, a means for re-ceiving the transmitted image of that form, and a computer con-nected to the receiving means.  The format on the paper form is prepared using a program on the computer, and a copy of that for-mat is stored in the computer.  The format includes option boxes, alphanumeric blocks for specific data collection and blank figure-8 boxes for collecting numerical information.  An operator of the computer selects the particular format required according to the needs of the location(s) having the transmitting means.  The for-mat is then transmitted to the location(s) either physically as a paper form or electronically over the telephone.  Personnel at the location(s) select from the various options on the paper form, and return an image of the form by telephone to the receiving means. Without requiring human supervision, the computer interprets the responses using its stored knowledge of the positions on the form at which the various options were placed when the particular for-mat was created.  The response may include data that the computer adds to data bases or may be a command such as asking the computer to send the current state of a data base by telephone to the loca-tion(s).

Abstract: Two corner cubes are opposed to share one or two mirror surfaces in common thereby integrally forming two mirror groups, and driven to be reciprocatively rotated in a plane including two opposite edges thereof or a symmetry plane including an edge defined by the two common mirror surfaces, while a beam splitter is provided in front of the two corner cubes for reflecting a part of incident light and guiding the same to one of the corner cubes as well as transmitting the remaining part of the incident light and guiding the same to the other one of the corner cubes while causing interference between light components reflected from the corner cubes.      According to the present invention, a moving mechanism may simply cause reciprocative rotation movement about one center of rotation, and adjustment in assembling is extremely simple and easy to allow reduction in manufacturing cost.      A double corner cube member, which can be formed of the same material, is stable against disturbance such as vibration and temperature change.      When plane mirrors for forming the corner cubes are manufactured by machining such as cutting or grinding, it is possible to perform assembling and working in high accuracy.

Title: Acoustic transducer
IPC: H04R17/00
Filed: 1991-05-15
Abstract: ABSTRACT          A broadly tuned transducer system for pulse echo ranging systems has a rigid plate, to a planar radiating front surface of which is applied at least one layer of acoustic coupling material having a density intermediate between that of the plate and an atmosphere into which the transducer is to be coupled.  Three or more driver assemblies spaced apart in a two dimensional array are rigidly secured to a rear surface of the plate,  each assembly having a loading block and a piezoelectric element compressed between the block and the plate.  The driver assemblies all have the same resonant frequency on axes perpendicular to the plate and are driven in phase; they occupy not less than one fifth and not more than four   fifths of the area of the rear surface of the plate, which is rigid enough to prevent the excitement  of  significant  flexural  oscillations.    The arrangement permits the transducer to have a large planar radiating surface whilst using quite small piezoelectric elements.

IPC: B22F1/00
Filed: 1991-08-21
Abstract: CERAMIC-METAL ARTICLES AND METHODS OF MANUFACTURE     ABSTRACT    A dense cermet article includiny about 80-95% by volume of a granular hard phase and about 5-20% by volume of a metal phase.  The hard phase is a carbide, nitride, carbonitride, oxycarbide, oxynitride, or carboxynitride of a cubic solid solution selected from W-Ti, W-Hf, W-Nb, W-Ta, Zr-Ti, Hf-Ti, Hf-Zr, V-Ti, Nb-Ti, Ta-Ti, or Mo-Ti. The metal phase consists essentially of a combination of nickel and aluminum having a ratio of nickel to aluminum of from about 90:10 to about 70:30 by weight, and 0-5% by weight of an additive selected from titanium, zirconium, hafnium,  vanadium,  niobium,  tantalum,   chromium, molybdenum, tungsten, cobalt, boron, and/or carbon.  The article may be produced by presintering the hard phase -metal phase component mixture in a vacuum or inert atmosphere at about 1475° 1675°C, then densifying by hot isostatic pressing at a temperature of about 1575°-1675°C, in an inert atmosphere, and at about 34-207 MPa pressure. Limiting the presintering temperature to 1475°-1575°C and keeping the presintering temperature at least 50°C below the hot pressing temperature produces an article of gradated hardness, harder at the surface than at the core. In this gradated product, the hard phase may alternatively be  a  carbide,  nitride,  carbonitride,  oxycarbide, oxynitride,  carboxynitride,  or boride of an element selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, or B.

Patent CA-2058937-A1 (CA)
Title: Semiconductor light emitting device
Inventor: PLUMB RICHARD G
IPC: H01S5/00
Filed: 1990-06-07
Abstract: A semiconductor device for amplifying radiation comprises an n-type substrate (1), a p-type layer (3) between which is located an active layer (2). Portions of the p-type layer (3) are removed by an etching process to create a central contact portion (11).  Typically, the p-type layer portions are removed by an etching process in combination with a photoresist mask deposited on the top surface of the p-type layer (3). By using an etching process the contact portion can be shaped so that the photoresist layer then overhangs the contact portion (11). N-type ions are then implanted into the active layer (2) where the p-type layer (3) has been removed and the overhanging photoresist layer (4) creates non-implanted regions (10) in the active layer (20) which separates the implanted regions (8, 9) from the contact portion (11). The implanted regions (8, 9) have the effect of creating a potential barrier between the non-implanted regions of the first layer and the implanted regions and this prevents current injected into the contact portion (11) from spreading horizontally in the active layer (2).

Filed: 1992-01-09
Abstract: A connecting device for integrated circuits or the like.      The disclosed device has a housing interposed between the lead of an integrated circuit and the respective terminal. A slot in the housing extends from one surface of the housing to the oppositely facing second surface. The slots, of which there can be a plurality, extends parallel to the axis of alignment of the lead and the terminal. The first surface has a trough proximate the integrated circuit lead. The second surface has formed therein a similar trough which is near the terminal.      The first mentioned trough receives a rigid first element extending across the slot or slots in which one or more contacts are received. The second mentioned trough receives an elastomeric second element. It also extends across the slot or slots. A planar contact or contacts is or are received in the slot or slots. Each contact has a protrusion to be engaged by an integrated circuit lead. The contact also has a nub normally extending outward from the housing toward the second surface of the housing to engage a corresponding spaced terminal. The contact further has a hook near the nub of the contact, which hook encircles the elastomeric second to hold the contact thereto. There is an elongated channel in each contact for receiving the rigid element. Relative movement occurs as the protrusion of the contact is engaged by, and urged inwardly into the housing by, an integrated circuit lead. The assembly functions as a result of the rigid first element moving relatively along the channel formed in the contact. The protrusion of the contact moves across the integrated circuit lead by which it has been engaged. The nub of the contact moves across the corresponding spaced terminal of the printed circuit board. A number of different embodiments is discussed in the disclosure.
