  • Patent number: 6137547
    Abstract: A projection type displaying apparatus with a movable built-in screen has an image display, an image projector and a position detector for detecting a position where the built-in screen is installed. When the position detector determines that the built-in screen is in an image projection pass, the focus of the image projector is adjusted on the built-in screen and the image projector projects the image onto the built-in screen. When the position detector determines that the built-in screen is out of the image projection pass, the focus of the image projector is adjusted on an external screen and the image projector automatically projects the image onto the external screen.

  • Patent number: 6133518
    Abstract: A keyboard, having a plurality of keys arranged so as to be pivotable upward and downward and a plurality of light emitters arranged under the keys in one-to-one correspondence therewith, selectively causes the light emitters to emit light, thereby teaching keys to be depressed. A base resin, which forms each of the plurality of keys, has transparency and contains a pigment which colors the base resin and a light scattering agent having a light diffusion property. By virtue of the use of the pigment and the light scattering agent, a surface color which confers a refined feature on the keys can be realized, and accordingly a product with an excellent appearance can be attained. Moreover, by virtue of the blending of the pigment and the light scattering agent, the keys can shine uniformly without a difference in brightness when their corresponding light emitters are lighted, and a keyboard instrument player can fully recognize by his/her eyes that the keys shine.

  • Patent number: 6130860
    Abstract: A transmitter includes a time measuring unit. The transmitter also includes a time information storage unit for storing information on the time measured by the time measuring unit when a specified process was performed. The transmitter is responsive to an instruction of transmission to transmit to a receiver information on the time difference between the time measured by the time measuring unit and the time whose information is stored in the time information storage unit. The receiver calculates the time when the specified process was performed by the transmitter on the basis of the information on the received time difference and information on the current time obtained by a time measuring unit. Thus, although the transmitter has no current time measuring unit, the receiver is capable of specifying the time when the specified process was performed.

    Abstract: When a desired plurality of document data are selected from a recorded plurality of document data and read into a text memory, the selected plurality of document data are combined into a document data string, and cut instruction data is added between any two adjacent document data. Printing lengths of a tape are calculated for the respective document data sectioned by the cut instruction data, so that positions where the tape is cut are calculated and then stored in a cut position memory. In connection with printing of the document string developed into a print data memory from the text memory, a cut instruction signal is output and the tape is cut each time the number of motor driving steps for tape carriage matches a respective one of the cut positions.

  • Patent number: 6124852
    Abstract: Two kinds of alternation signals, that is, an alternation signal for odd-numbered electrodes and an alternation signal for even-numbered electrodes, are input to an SEG driver. In accordance with those signals, the SEG driver reverses, at different timings, the polarity of SEG drive signals which are output to odd-numbered signal electrodes and the polarity of SEG drive signals which are output to even-numbered signal electrodes. As a result, spikes are generated before and after the timing of a polarity reversal of an alternation control signal which is input to a COM driver. Further, the SEG driver reverses, at the same timing and in different directions, the polarity of the SEG drive signals which are output to the odd-numbered signal electrodes and the polarity of the SEG drive signals which are output to the even-numbered signal electrodes. By so doing, the crosstalk due to the spikes is reduced.

  • Patent number: 6124909
    Abstract: In a liquid crystal display device using color filters, the area of each of color filters arranged on the inner surface of one of substrates in correspondence with the pixel areas is set to be smaller than that of each pixel area to form non-colored light exit areas, and color pixels are displayed with non-colored light which is not transmitted through the color filters and colored light which is transmitted through the color filters. Since high-luminance color pixels are displayed with these colored light and non-colored light, the screen can be made brighter. The liquid crystal display device further includes a reflecting member for reflecting external light incident from the front side of the device and transmitted through the liquid crystal layer toward the front side.

  • Patent number: 6118458
    Abstract: An image displaying apparatus stores plural image data and displays one of the image data, which image data represent a growing plant (animal) or represent a series of motions of an animal. The apparatus further stores plural element data for growing the plant (animal). When one of the element data is selected, another image data of the plant (animal) is displayed in place of the previously displayed imaged data to show how the plant (animal) grew up responsive to the selected element data. The apparatus is provided with a sensor for detecting motion of a user. Detecting the motion of the user, the apparatus displays new image data representing a motion of the animal in place of the previously displayed image data to show how the animal reacts to the user's motion.

  • Patent number: 6115014
    Abstract: One frame of a video signal is separated to a plurality of display frames. To display a color specified by the video signal by mixing display colors of a plurality of display frames, the video signal is converted to data indicative of a voltage to be applied to each pixel over the display frames by using a conversion table. A voltage corresponding to the converted data is applied to a birifringence control type liquid crystal display device to drive the liquid crystal display device multiple times in one frame period of the video signal. When the response speed of the liquid crystal is fast, a color obtained by mixing the display colors of a plurality of display frames is recognized by an observer. When the response speed of the liquid crystal is slow, a color corresponding to an average value of the voltages applied to a plurality of display frames is recognized by the observer.

  • Patent number: 6111658
    Abstract: A ROM in the control circuit of a color printer stores a threshold matrix. The individual elements of the threshold matrix correspond to print dots, the number of which is X.times.Y and which form 1 pixel in the original image. Values t (x, y) which are integral numbers not less than 0 are assigned one to each of the individual elements in a predetermined order. Using the threshold matrix, the CPU of the control circuit creates mask patterns for representing halftones. A value of 1 is subtracted from the tone number allotted to the tone of color of a pixel in an image to be printed, and the resultant value is substituted for a variable G. When a gradation for image data representing the pixel is given as "g", the condition required for setting ON (transferring toner to print) the dot specified by the coordinates (x, y) in the pixel in the case of the gradation "g" is expressed by the following formula (6):t (x, y).ltoreq.g.times.X.times.
