Abstract: A control system of a game apparatus such as a racing game apparatus has a CPU for controlling a signal processor based on a program stored in a computer-readable recording medium to process three-dimensional image data for perspective projection and horizontal image distortion correction for images to be projected onto a curved projection screen. The CPU also controls an image display processor to write the processed image data into a RAM, from which the image data is supplied to an image projector to project the images onto the curved projection screen. The curved projection screen gives a game player, e.g., a racing car driver, a horizontally long panoramic view in front of the game player, so that the images displayed on the curved projection screen look wide and realistic.

Abstract: A DES permutation is presented that has minimal crossovers between the DES 64-bit structure and 32-bit data structures, allows for efficient data transfers via a 32-bit data bus. Every other bit location in the DES 64-bit data structure is mapped to a contiguous bit location in the 32-bit data structure, in a sequential order. The sequential mapping to contiguous bit locations minimizes potential crossovers that are area inefficient, and allows for encoding algorithms that effect the mapping by using incrementing or shifting operators only.

Title: Device for paste coating
Inventor: KAWASUMI YUKIHIRO
IPC: B05D1/26
Filed: 1999-08-27
Granted: 2001-11-21
Abstract: To facilitate the rapid adjustment of the coating quantity of paste to form a paste pattern having a desired shape with high precision. While changing the relative position relation of a nozzle 13a and an actual substrate 22, by discharging paste 23 from a discharge port of the nozzle 13a, a desired paste pattern is formed on the surface of an actual substrate 22. In this case, when the nozzle 13a reaches a position on the actual substrate 22 determined as a change point in advance, the distance for the surface of the actual substrate 22 to the paste discharge port of the nozzle 13a, that is, the coating height is changed from a coating height 1 to a coating height 2 set in advance, and accordingly, paste discharge from the nozzle 13a is changed. In this way, coating paste thickness can be changed more quickly than changing of pressure applied to a paste housing cylinder provided with the nozzle 13a.

Patent TW-448691-B (TW)
Title: Analog video tagging and encoding system
Inventor: BARTON JAMES M
IPC: H04N7/025
Filed: 1999-11-05
Granted: 2001-08-01
Abstract: An analog video tagging and encoding system. The invention inserts an analog tag frame into the analog video stream such that the luminance (Y) values are made to approach zero, i.e., black, allowing a potential tag frame to be quickly identified. Tag information is then encoded as a structured color pattern into the chrominance (Cb and Cr) portions of the frame, making the tag itself invisible to the casual viewer and contains program start/stop information, program segment identification, or data downloads. The color pattern is chosen such that when it is converted into digital form, the digital signal so produced may be easily and minimally parsed to recognize the presence of absence of a tag within a normal frame time period. In a simple embodiment of the invention, the structured analog color pattern may appear as a pattern of colored blocks aligned with the macroblock segmentation performed on the analog signal by the MPEG encoding process, causing the DC component of the encoded Cr and Cb macroblocks to precisely reflect the color pattern. The simplest color pattern uses two colors with extremely different Cr or Cb values, and derives a binary encoding sequence where a binary one (1) represented by values near the other color and is easily extended to create a number of different chrominance levels within each encoded macroblock, allowing multiple bits of tag information to be encoded by each macroblock. Another embodiment of the invention provides a method whereby ""trimming"" of the analog signal (i.e., truncation of the signal in the vertical or horizontal direction during transmission) has no effect on the ability to derive the tag from the encoded frame. A window is selected within the tag frame such that the size of the window is known to most likely fit within a trimmed frame and transmitted in its entirety with the tag information redundantly encoded within or outside the window to guarantee that no portion of the tag information is omitted whenever the frame is transmitted. Square colored blocks of a multiple of the macroblock size are used such that a phase encoding is achieved which is easily detected during a single pass over the MPEG bitstream. To insure that all tag data is present, the tag frame is preceded and possibly followed by ""reset"" frames which are exactly opposite from the tag frame, forcing the MPEG encoder to generate all macroblocks for the tag frame, regardless of whether the current frame is an I-frame or not.

Title: Control panel for electronic equipment and method of producing the same
Inventor: NARITOMI MASANORI
IPC: H01H13/70
Filed: 1999-12-15
Granted: 2002-08-11
Abstract: A control panel for electronic equipment that satisfies the requirements of hermeticity, clearness of indication and operability and yet allows a cost reduction. A sheet made of a commercially available light- transmitting thermoplastic synthetic resin material is used as a substrate. Sheet recesses are formed on the sheet so that each print layer formed on the surface of the sheet is located on the inner side of the bottom of a sheet recess. The sheet recesses are filled with a synthetic resin material to form pushbuttons. A contact surface of a case cover and a contact surface of a pushbutton outer skin are kept in close contact with each other during injection molding. Therefore, there is no possibility of the resin material flowing between the contact surfaces. It is unnecessary to insert a mold member into the clearance between each pushbutton and the associated opening in the case cover. Because the clearance can be minimized, it becomes easy to achieve a size reduction and so forth. Design limitations are also reduced.

Abstract: This invention is about fabricating method of buried bit line and is briefly described as follows. At first, a substrate with a silicon substrate, a first insulation layer and a silicon epitaxy layer is provided, wherein the insulation layer contains silicon. After that, shallow trench isolation that contacts with the first insulation layer is formed in silicon epitaxy layer. A trench that penetrates shallow trench isolation and goes deep into the first insulation layer is formed in substrate. Buried bit line with its surface located in between the upper surface and the lower surface of shallow trench isolation is then formed in the trench. The second insulation layer is formed on the buried bit line such that its surface is coplanar with the surface of silicon epitaxy layer. Several word lines and several source/drain regions are formed individually on top of substrate and in silicon epitaxy layer. The third insulation layer with its surface coplanar with the word line surface is formed on top of substrate and fills up in between the word lines. After that, self-aligned contact window process is performed. The contact window opening of bit line that exposes buried bit line and part of source/drain region is formed in between word lines. Finally, bit line contact is formed in the contact window opening of bit line.
