Title: Vehicle lamp system
Inventor: KUNG THOMAS L
IPC: B60Q1/14
Filed: 1985-12-13
Granted: 1992-06-16
Abstract: Case 2955 VEHICLE LAMP SYSTEM           Abstract of the Disclosure A vehicle lamp system makes provision for a pair of daytime running lights.  While the system particularly lends itself to dual filament sealed beam lamps, in which one of the filaments in a lamp is used for running light purposes, it may also be incorporated with a system using replaceable bulb units.  In view of the safety aspects involved a particular control switch system is used, in order to assure automatic employment of the lights when the vehicle is driven during daylight hours.  In particular, the arrangement encourages the adoption of a four-lamp system.  In order to promote running light longevity in excess  of  the life expectation of the other lamp filaments of the system, the running lamp filaments are connected in series relation which promotes long life while supplying an appropriate light intensity.  By combining the subject running light filaments in a dual beam lamp construction, in which the second filament is for "low" beam illumination, in a four-lamp arrangement the high beam provisions for the system can be provided by lamps dedicated to high beam usage.

Title: Retractable work station
Inventor: MCINTOSH LAWRIE
IPC: A47B21/03
Filed: 1986-08-26
Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE A retractable work station suitable for use with a computer keyboard has a parallel swing-link suspension for selectively moving a working platform surface from a fully retracted position, to an advanced working position, while maintaining unchanged the inclination of the platform surface. The apparatus is equipped with a brake for immobilizing the linkage in any desired intermediate position. The platform is adjustably secured to a moveable frame portion of the apparatus so that the inclination of the work platform can be selectively adjusted. One embodiment incorporates tension springs to urge the platform towards either one or the other of its bi-stable positions i.e. fully retracted or fully extended. An inverted embodiment of the apparatus maintains itself in a selected one of its two bi-stable positions without the need for springs. The shape of the respective links of the suspension assures the maintenance of an adequate free space over the platform when retracted, for storage of a keyboard apparatus thereon.

Abstract: SPIRAL COIN-QUEUEING HEAD FOR HIGH-SPEED          COIN-SORTING AND COUNTING APPARATUS               Abstract of the Disclosure A coin-queueing head for use in a high-speed coin-sorting and counting apparatus is provided using a spiral coin processing channel.  Coins are fed from a central loading area through an infeed opening into an infeed area having a height permitting unrestricted outward travel of the coins to a peripheral limit having a generally helical shape.  The coins are then fed into a coin-processing channel having a first portion for partially separating face-stacked coins.  The coins then pass to a second ramped channel portion providing a gradual depressing of the coins and a sudden release into a third channel portion.  An inwardly positioned camming lobe and an outwardly positioned expanded area are provided to facilitate lateral separation of the coins upon their release from the second channel portion.  The trailing end portion of the third channel portion has a height to relieve the coins of all restriction and the peripheral limit is sloped upward to provide a smooth transition of the coins from their helical path to the circumferential peripheral rim of the disc. Recirculation is provided into the infeed area of coins positioned too far inward at the entry into the first channel portion.

Abstract: ABSTRACT           This application discloses a novel thermal ink jet printhead and related integrated pulse driver circuit useful in  thermal ink jet printers.   This combined printhead  and pulse  drive  integrated circuit includes a first  level  of metalization   comprising   a  refractory  metal  which   is patterned  to define the lateral dimension of the  printhead resistor.   A passivation layer or layers are deposited atop this  first level of metalization and patterned to  have  an opening  or openings therein for receiving a second level of metalization.   This  second level of metalization  such  as aluminum  may then be used for electrically  interconnecting the printhead resistors to MOSFET drivers and the like which have  been  fabricated in the same silicon  substrate  which provides  support for the printhead resistors.   Thus,  this "on-chip"  driver  construction enables these  pulse  driver transistors  to be moved from external electronic  circuitry to the printhead substrate.

Title: Integrated circuit comprising load resistors, arranged as thin-film elements on the field oxide zones which separate the active transistor zones, and processes for the production thereof
Inventor: WINNERL JOSEF
IPC: H01L27/06
Filed: 1987-11-17
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE         In an integrated circuit containing MOS transistors and/or bipolar transistors, the load resistors, which are arranged as thin-film elements on the field oxide zones which separate the active transistor zones, consist of polycrystalline silicon which is formed simultaneously with gate electrodes and/or the emitter and base terminal zones of the bipolar transistors on a substrate which contains the integrated circuit.  The structuring of the load resistors is carried by way of an oxide mask which serves as an etch stop during the structuring of the gate electrode composed of a double layer of polysilicon and a silicide of a refractory metal.  As only the polysilicon of the gate layer without overlying silicide is used for the load resistors, the sheet resistance of the load resistors can be set independently of that of the gates.

Granted: 1992-05-12
Abstract: ABSTRACT     It is known to use a miss information holding register in a cache memory organization to store the details of a CPU load request on a cache miss so that the cache may accept subsequent requests pending the receipt of data in respect of the first request.  In the subject invention, this organization is modified for use with a virtual addressable cache memory by incrementing a counter which overflows to free the miss information holding register with each untranslatable response signal from the address translation unit relating to the request stored in the miss information holding register.  The modified organization also clears the used bit associated with the location in the cache tag memory to which the tag address of the request has been stored upon receipt of the first untranslatable response signal from the address translation unit in respect of the request.

Abstract: Abstract:   A semiconductor device is produced by the following process.  Ionized material is poured to a predetermined depth in a silicon substrate to form an etching stopper layer.  A predetermined area of the silicon substrate is then etched to the depth of the etching stopper layer to form a recess.  A compound semiconductor chip is then located in the recess, and an insulating film is formed covering the space between the walls of the recess and the side walls of the chip so as to be patterned.  Then a second thin film circuit is formed on the patterned insulating film so as to connect electrodes of the chip to a first thin film circuit that has previously been formed on the surface of the substrate.  The resulting device is capable of high density packing and high speed operation.

Filed: 1988-05-10
Granted: 1991-10-08
Abstract: Abstract of Disclosure A Doppler navigation system includes an altimeter section with increased accuracy resulting from closed loop operation of signal processing portions for reflected signals including phase shift information. Quadrature processing of the reflected signal includes compensation for differences between quadrature processing channels, wherein the reflected signals are periodically processed by alternate ones of the channels.  A maximum amplitude signal is forwarded by the signal processing portions to a frequency tracker of the navigation system.  Periodic calibration of the altimeter section corrects for delays introduced in the signal processing portions.   Effects of FM to AM conversion in a Gunn oscillator are reduced by connection of the signal processing portions to a short circuit during the calibration periods.
