Granted: 1998-12-08
Abstract: An improved color correction system and method are disclosed.  A color corrector may include circuits for selecting a predetermined range of colors around an infinitely selectable principal color and circuits for selectively generating color corrections for the video picture signals which correspond to the predetermined range of colors.  The color corrections are then applied to the video picture signals to produce color corrected video picture signals.  The color corrections may be stored and recalled on a scene-by-scene basis.  Two or more such circuits may be employed so that two or more different principal colors can be selected.  Preferably, the predetermined range of colors is adjustable.  A color corrector may also include circuits for storing and recalling area discrimination signals on a scene-by-scene basis.  Moreover, a color corrector may include circuits for identifying the color corrections for a particular scene with a video picture from that particular scene.  The video picture for the particular scene is displayed, and the operator may recall the color corrections by using the video picture together with an associated control.  More particularly, the improved color correction system utilizes an improved color detector for selecting a range of colors around an essentially infinitely variable center color.  The center color is adjustable through an angle of 360° or more, while the passband may be adjusted to be broad or narrow, e.g., changed from ~ 2° to ~ 90° about the center color.

Title: Trench sidewall isolation by polysilicon oxidation
Inventor: FULTON INGE G
IPC: H01L21/74
Filed: 1987-04-08
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a process of growing a conformal and etch-resistant silicon dioxide on a surface by forming a conformal layer of polysilicon and subjecting the polysilicon to thermal oxidation to completely convert the polysilicon into (poly) silicon oxide.    Disclosed also is a method of forming an isola-tion trench in a semiconductor substrate having a high integrity oxide sidewall.  After forming the trench in the substrate surface using a suitable etch mask and RIE, a single (thermal) oxide or dual (thermal) oxide and  (CVD)  nitride  liner  is  formed  on  all  trench surfaces.  A conformal layer of undoped polysilicon is then formed (by. e.g. LPCVD) on the liner. By subject-ing to thermal oxidation, the polysilicon is complete-ly converted into a conformal  (poly)  silicon oxide layer having a thickness about 2.5 times that of the polysilicon layer.  The resulting (poly) silicon oxide has the conformality of CVD oxide and the high etch resistance of thermally grown oxide.    Alternatively,  prior  to  forming  the   (poly) silicon oxide, the polysilicon layer is removed from the trench floor and the substrate surface in order to limit volume expansion of the polysilicon to a single direction perpendicular to the trench walls.    The  trench  is  filled  with  oxide,  epitaxial silicon, polysilicon, polymers or metal, as desired.          For achieving substrate contact through the trench, the trench bottom is opened up by RIE. Polysilicon is deposited with in-situ doping at a high temperature to fill the trench and simultaneously diffuse the dopant from the polysilicon  fill  into the underlying sub-strate to form a channel stop.

Abstract: ABSTRACT OF THE DISCLOSURE     A sensor is used in a retractor of a seat belt apparatus of a vehicle for winding a webbing to be fastened on an occupant of the vehicle and serves to prevent a webbing take-up shaft from rotating in the direction where the webbing is wound out.  A bracket which supports an inertial body is mounted on the retractor through mounting means which allow the angle at which the bracket is mounted on the retractor to be selectively altered.  Therefore, a constant acceleration response characteristic can be maintained even if the retractor is mounted on the body of the vehicle at different angles.

Abstract: PROGRAMMER FOR IDENTIFICATION SYSTEM                   Abstract of the Disclosure A tag has a memory programmable to store alphanumeric indications in a pattern identifying an object associated with the tag. The stored indications are convertible to signals transmitted to a displaced reader in an individual pattern at first and second frequencies to identify the object.  The memory may be programmed, during the production of a first logic level in a signal on a program pin, (a) by the operation of keys on a keyboard in a programmer housing, each key representing an individual alphanumeric character, or (b) from an external source such as a typewriter keyboard used in conjunction with the programmer.  The signal on the program pin has a second logic level to provide for bulk erasing all particular memory positions.  A configuration signal has a first logic level providing for the alphanumeric coding of the memory and a second logic level providing for the selection, at particular memory positions, of individual capacitors to generate signals at the first and second frequencies.  When the programming signal has the second logic level and the configuration signal has the first logic level, bulk information may be erased from the memory.  Dependent upon the logic levels of the programming and configuration signals, (1) information is programmed in the memory, (2) the capacitors are selected or (3) programmed information is bulk erased when an energizing pin in the programmer receives a particular voltage.  A detent on the tag has a plurality of pads for introducing the different logic levels to the programming, configuration and energizing pads in the tag. This detent mates with a detent in the programmer housing to provide for the introduction of the programming, configuration and energizing signals to the tag through the pads in the tag detent,

Abstract: Abstract The invention relates to an apparatus for the manufac-ture of  insulating chutes.  The apparatus  comprises means for winding plies of insulating material on to cores; means for curing the insulating material wound on the cores; means for removing cured insulating ma-terial from the cores; and means for returning empty cores to the winding step. The object is to make the operation of this kind of apparatus more efficient than previously. The object is achieved in such a man-ner that the cores (12) are arranged in groups on an endless  transporter  (1),  whereby  empty  spaces corresponding to the number of cores in a group are left between the groups of cores, and the transporter is arranged to move step by step a distance corre-sponding to the interspace between individual cores in a group when the first core in each group reaches the winding means, and a distance corresponding to the in-terspace between the groups when the last core in each group leaves the winding step. When the transporter is displaced a distance corresponding to the interspace between the groups, the whole group of cores is intro-duced into the curing means (5), in which the group of cores is detached from the transporter for the time of the curing, being thereafter returned to the following empty space on the transporter.

Abstract: A porous substrate is formed from discrete elements preferably anisotropic and permeable to oxygen and preferably having a first coefficient of thermal expansion.  A pyrolytic material permeable to oxygen may be deposited in a thin layer on the discrete elements.  A barrier material (e.g. boron carbide or silicon carbide) may be deposited in a thin layer on the pyrolytic material to inhibit diffusion of elements into the pyrolytic material.  A material impermeable to oxygen (e.g. boron nitride or silicon nitride) may be deposited in a thin layer on the barrier material.  A refractory matrix permeable to oxygen may be deposited on the impermeable material.  The matrix may include a metallic element (e.g. silicon, hafnium, tantalum or zirconium) and another element (e.g. oxygen, nitrogen, carbon or boron) chemically bonded to the metallic element.  The matrix may have a second coefficient of thermal expansion different from the first coefficient and may have a minimal bond to the substrate.  The matrix is accordingly able to move relative to the substrate with changes in temperature, partly because the pyrolytic material contributes to a shear between the matrix and substrate.  A refractory material impermeable to oxygen may be deposited in a thin layer on the matrix and may include a metallic element (e.g. silicon, hafnium, tantalum or zirconium) and an element (e.g. oxygen, nitrogen and boron) chemically bonded to the metallic element.  The different layers may be deposited on the substrate, each in a substantially uniform thickness, at an elevated temperature and at pressures pulsating at a particular rate, and in reverse directions, between first and second particular limits.
