Inventor: RODDER MARK S
IPC: H01L21/336
Filed: 1997-10-27
Granted: 1999-09-11
Abstract: A method for forming a MOSFET transistor (100) using a disposable gate (120). A disposable gate (120) having at least two materials (122, 124) that may be etched selectively with respect to each other is formed on a semiconductor substrate (102). Source/drain region (104) are then formed adjacent to the disposable gate. The source/drain regions may, or for example, include raised source/drain region (106). An insulator layer (114) is then deposited over the structure and then a portion of the insulator layer (114) over the disposable gate (120) is removed (e.g., using CMP or an etch-back). The composition of the insulator layer (114) is chosen such that the top layer (124) of the disposable gate (120) may be removed selectively with respect to the insulator layer (114). The disposable gate (120) is then removed and a channel implant may be performed that is self-aligned and only in the channel region. The gate dielectric and gate electrode (112) are then formed.

Abstract: The purpose of the present invention is to provide an image displaying apparatus which can select, display the virtual world in a sense of reality corresponding to each stage of images in the growing up process of living things, and which can provide a kind of image display control device to control the display of images more delicately depending on the selection and the recognition of users so that it only displays images of those living things which grow corresponding to the given growing elements, so that users of the apparatus can have the feeling of raising up living things (animal, plant) more real. Select the most appropriate image data of growing elements depending on the arbitrary choice of users from the stored plurality of image data of growing elements to correspondingly display the growing image of living things. Examine whether the growing element data value selected by the user is predefined or not. In response to the examination result, the growing process image currently displaying or the next growing process of the living things can be displayed. Furthermore, control without updating the specified data required by specifying the image of living things in the next growing process to respond to the examination result in the same way, the current growing process image displaying or the next growing process of the living things can still be displayed. Also, since users can arbitrarily select at least two kinds of image data of growing elements, users can have feeling of actually raising living things by mixed growing elements (e.g. two kinds of elements such as water and forage, etc.) even more real. The image of current growing process or the next growing process of the living things can be read out from the image of living things in the plurality of living processes previously stored in ROM and displayed.

Title: USB peripheral microcontroller
Inventor: DUNNIHOO JEFFREY CLAY
IPC: G06F13/38
Filed: 1998-04-28
Granted: 2001-04-01
Abstract: The present invention relates to a peripheral microcontroller for providing a high performance USB (Universal Serial Bus) connection to existing peripheral architectures (such as printers and disk drives with existing microcontrollers) and to new peripheral architectures (such as a 4-port USB-to-Ethernet Bridge). The USB peripheral microcontroller includes three units. A Serial Interface Engine (SIE) connects to a USB host or USB hub. A Microcontroller (MCU) Interface Unit connects to one or more peripheral devices such as ISA-like peripherals. A Memory Management Unit (MMU) provides a buffering mechanism between the SIE and MCU Interface Unit. The MMU utilizes a unique data packet buffering architecture. Packets received at the MMU from a peripheral for transmission to the USB host and packets received at the MMU from the USB host for transmission to a peripheral are buffered in a RAM. The capacity of the RAM is dynamically allocatable among various USB endpoints and the USB host so that the size of the RAM is minimized. The data path of the inventive USB peripheral controller is also highly advantageous. The SIE accesses the packet buffer RAM via a DMA controller in the MMU. The MCU Interface Unit accesses the packet buffer RAM via a microcontroller or a DMA controller. An arbiter in the MMU enables these multiple masters to access the packet buffer RAM.

Title: Rotary gas valve device
Inventor: MIZUTANI KEIICHI
IPC: F23Q3/00
Filed: 1998-06-16
Granted: 2000-09-21
Abstract: A gas valve device includes: a gas cock (2), a safety valve (3) opened and closed in a direction transverse to axis of the gas cock (2), and an ignition switch (4). A bar is operably rotatably to move the gas cock toward an open side, press open the safety valve, and press a press piece (4a) of the ignition switch (4) in order to turn ON the ignition switch (4). When the safety valve (3) is in a press-switch state, but the press piece (4a) of the ignition switch (4) is not fully pressed, the aim is to permit full pressing of press piece (4a) to ensure turning ON of the ignition switch (4). The solution is to divide the bar into a first bar for the ignition switch and a second bar for the safety valve. The first bar (7) is movable with and is rotated by an operating axle (6) of the gas cock (2). The rotary force of the first bar (7) is transmitted to the second bar (8) via a spring component (9). When the safety valve (3) is press-switched, the second bar (8) rotates intermittently. By virtue of the spring deformation of the spring component (9), the first bar (7) rotates continuously such that the press piece (4a) of the ignition switch (4) is fully depressed, and turning ON of the ignition switch (4) can be ensured.

Title: Cache coherency protocol with tagged state and historical information
Inventor: ARIMILLI RAVI KUMAR
IPC: G06F12/0815
Filed: 1998-07-13
Granted: 2000-01-01
Abstract: A cache coherency protocol uses a ""Tagged"" coherency state to track responsibility for writing a modified value back to system memory, allowing intervention of the value without immediately writing it back to system memory, thus increasing memory bandwidth. The Tagged state can migrate across the caches (horizontally) when assigned to a cache line that has most recently loaded the modified value. Historical states relating to the Tagged state may further be used. The invention may also be applied to a multiprocessor computer system having clustered processing units, such that the Tagged state can be applied to one of the cache lines in each group of caches that support separate processing unit clusters. Priorities are assigned to different cache states, including the Tagged state, for responding to a request to access a corresponding memory block. Any tagged intervention response can be forwarded only to selected caches that could be affected by the intervention response, using cross-bars. The Tagged protocol can be combined with existing and new cache coherency protocols. The invention further contemplates independent optimization of cache operations using the Tagged state.

Title: Interrupt mechanism using TDM serial interface
Inventor: JAJIL FADAVI-ARDEKANI
IPC: H04M1/00
Filed: 1998-08-31
Granted: 2000-03-11
Abstract: An improvement to split-architecture audio codecs such as those defined by the Audio Codec '97 specification (AC '97) includes an interrupt mechanism which allows an event at an analog peripheral device such as an incoming call to be sensed by the AC analog sub-system and initiate a wake up procedure in the split-architecture audio codec system. The interrupt mechanism includes a masked interrupt register which is responsive to an interrupt signal from an audio source, such as a ring detect from an incoming telephone line. Either the AC controller sub-system or the peripheral analog device via the AC analog sub-system can initiate a wake up procedure. The AC controller sub-system includes a static divide by 256 counter responsive to a bit clock signal. The bit clock signal is sensed at the AC controller sub-system to determine an operating mode. Upon detection of at least 256 bit clock cycles after a predetermined minimum time for the AC analog sub-system to be in a halted or sleep mode, a wake up interrupt register is enabled in the AC controller sub-system. The interrupt sensor is opto-coupled to the AC analog sub-system, and the interrupt signal from the interrupt sensor is communicated to the AC controller sub-system via the five-wire TDM serial bus between the AC analog sub-system and the AC controller sub-system.

Title: Pulse energy control for excimer laser
Inventor: SANDSTROM RICHARD L
IPC: H01S3/137
Filed: 1998-09-18
Granted: 2000-04-21
Abstract: A process for controlling pulse energy and integrated energy dose in bursts of pulses produced by an excimer laser. The energy of each pulse in each burst is measured. The rate of change of pulse energy with charging voltage is determined. A pulse energy error is determined for a previous pulse of the present burst. An integrated dose error is also determined for all previous pulses in the curent burst. A charging voltage for the next pulse is determined using he pulse energy error, the integrated dose error, the rate of change of energy with charging voltage and a reference voltage. In a preferred embodiment, the rate of change of energy with voltage is determined by dithering the voltage during two pulses of each burst, once lower and once higher. The reference voltage is a voltage calculated using prior energy and voltage data. In this embodiment, the method of determining the reference voltage during a first portion of the pulse is different from the method used during a first portion of the pulse is different from the method used during a latter portion of the burst. During the first set of pulss (40 in this embodiment), for each pulse, a specified voltage calculated using voltage and energy data from a corresponding pulse in a previous burst is utilized as a prediction of the voltage needed to produce a pulse energy converging on a target pulse energy. For pulses 41 and thereafter the reference voltage for each pulse is the specified voltage for the previous pulse.
