Title: New process to generate amplitude modulated signals
Inventor: MAEDA TSUNEO
IPC: H03C1/00
Filed: 1982-06-16
Abstract: The amplitude modulator includes a pulse generator (1-3) which supplies pulses at a carrier frequency to a pulse width modulator (4) to which a modulation signal is applied from a source of modulation signals (5-9) to produce a bipolar pulse width modulated signal which then is passed through amplifiers and filters (10-12) to produce an amplitude modulated output signal. To prevent nonlinear operation, the modulation signal is modified in a correction amplifier (9) before application to the modulator (4). In a modified embodiment the output of the pulse width modulator (4) is converted into two square wave pulse trains, phase shifted relative to each other, by monostable and amplifying circuits (10-14), and the two pulse trains are combined in a transformer (15) to produce the bipolar pulse width modulated signal. Since the components of this circuit are operating in the switching mode, high efficiency operation is obtained.

Title: Growth-modified thermal oxidation process for thin oxides
Inventor: ROY PRADIP K
IPC: H01L21/316
Filed: 1989-12-18
Abstract: GROWTH-MODIFIED THERMAL OXIDATION PROCESS FOR THIN OXIDES Abstract A method is disclosed for growing relatively thin (e.g.,<25 nm) thermal oxides which results in lowering the defect density, mobile ion concentration, interface trapped charge density, and stress of the structure. Inparticular, the prior art oxidation process is modified to include in situ preoxidation silicon surface treatments to improve the silicon nucleation surface. For example, gettering operations may be performed to remove metal-ion contaminants from the silicon nucleation surface, and high temperature annealing operations may be performed to remove any local stress gradients which exist in the silicon substrate during the initial stages of oxidation. By improving the silicon nucleation surface, the subsequently grown thin oxide will be improved in terms of the qualities mentioned above.

Title: Shoe strap for skateboarding
Inventor: PARIS LUIS E
IPC: A43B5/00
Filed: 1990-03-15
Abstract: Abstract:   When a person that is riding a skateboard wants to execute a jump with it, he/she must go through certain very specific body motions.  Those motions generate a lot of friction between the outer edge of the shoe of the skateboarder and the board surface.  Due to the abrasive nature of the surface of the skateboards, and because of the above mentioned friction, in a very short time an experienced skateboarder will develop a hole on the side of his shoe.  The devise subject of this patent application is detachable strap,specifically designed for skateboarding, that has two purposes.  The first purpose of the devise is to prevent holes in the outer sides of the shoes when jumping with the board; this goal is achieved by means of a protective surface attached to the strap.  The second purpose of the devise is to provide the friction point between foot and board, with added friction (as compared to the use of unprotected shoes).  This added friction helps control the skateboard more efficiently and thus makes it easier to perform higher jumps; this goal is achieved by means of an adhesive rubber sticker attached to the protective surface.

Abstract: ABSTRACT     A novel locking mechanism and specific applications for same are disclosed.  One aspect of the invention provides a product security system having a locking mechanism for preventing sliding movement between a slidably juxtaposed product container and product container locking structure, and a separate decoupling unit.  The decoupling unit has a frame adapted to receive the slideably juxtaposed parts, and means within the frame adapted to disengage the locking mechanism, thereby permitting sliding decoupling of the parts.  The locking mechanism has a magnetically attractable pin in a blind hole in the first part and a detent opening or recess in the second part.  The pin is moveable between a first position in which the pin enters the detent, thereby preventing sliding movement between the first and second parts, and a second position in which the pin is retracted into the blind hole from the detent, thereby permitting sliding movement.  Means are provided for biasing the pin into the first position.  One particular embodiment of the invention is a locking kit for a box having a hinged lid, such as a video cassette box.

Title: Method and apparatus for processing a complex hierarchy of data objects
Inventor: ABRAHAM ROBERT L
IPC: G06F3/048
Filed: 1990-08-20
Abstract: ABSTRACT OF THE DISCLOSURE       METHOD AND APPARATUS FOR PROCESSING A COMPLEX           HIERARCHY OF DATA OBJECTS        The  method  and  apparatus  of  the  present invention may be utilized to process a complex hierarchy of interrelated data objects so that a system user may rapidly and efficiently traverse the hierarchy from a first selected data object within the hierarchy to a second  selected data  object without  the necessity  of manually returning to a known point or "root" within the hierarchy.   Each  time  the  system  user  traverses  the hierarchy from a known point to a selected data object, the data  objects  encountered during the  traverse  are stored, along with a set of actions which were necessary to  traverse  the  hierarchy  to  that  point.   Upon  an indication by the user that a second selected data object is required,  the system will automatically display the existing path from the known point within the hierarchy to the selected data object in current utilization and the user is then permitted to alter the data objects and actions contained therein to reflect a "path" to a second data object.  Thereafter, the system will automatically traverse the complex hierarchy along this newly created path to arrive at the second selected data object.   In one embodiment of the present invention, a selected path to a known data object may be saved or "bookmarked" to permit the user to selectively return to that particular data object at any time in the future.
