  • Patent number: 5556670
    Abstract: A flexible liquid crystal display panel includes spacers and cross members which are prevented from moving and from exfoliating, respectively, even when a force is applied thereto. In this panel, upper and lower substrates have flexibility, and spacers coated with an adhesive are fixed to orientation films formed on the substrates, by means of the adhesive. Thus, even when a force is applied from the outside, the spacers are prevented from moving, and therefore the distance between the substrates can be kept constant and the display characteristics of the liquid crystal can be made uniform. Further, a sealing member interposed between the substrates has holes through which cross members are fitted. This means that the cross members are reinforced by the sealing member, and hence they can be prevented from exfoliating from the substrates, keeping good electrical connection.

  • Patent number: 5553172
    Abstract: An electronic image pickup apparatus picks up an object image such as an image on a blackboard and outputs the image. The apparatus can synthesize a picked-up image with format data input from another unit and output the synthesized image. When synthesis processing is to be performed, format data to be synthesized are created and stored in several line buffers in advance. When a picked-up one-line image signal is written in a line buffer of 1 line, the format data stored in the several line buffers are read out, and the image signal and the format data are synthesized in the line buffer of 1 line. By outputting the data in this line buffer in units of lines, the synthesized data obtained by synthesizing the picked-up image with the format data is output.

  • Patent number: 5547076
    Abstract: In a packaging structure, a tongue-like portion is formed in one end portion of a base to extend toward an end of the one end portion. A wristwatch, having a pair of watchbands with a band keeper being provided on one of the bands, is placed on the base, and the tongue-like portion is inserted into an opening of the band keeper through a gap of the band keeper and the corresponding watchband. A pillow portion is formed in the one end portion of the base at a region which is nearer to the end of the one end portion than the tongue-like portion. The pillow portion covers the tongue-like portion, and an extending end of the one of the watchbands lays on the pillow portion in a longitudinal direction of the base.

  • Patent number: 5546565
    Abstract: An input/output apparatus records both a handwritten image and a speech to facilitate the collation between the recorded image and speech. When a command recognizing section recognizes that a handwritten image input through a coordinate input section is a voice command image, a voice processor starts recording the speech, input from a microphone, into a voice recording memory. During this recording, the voice processor sets the input handwritten image as a key image. When an end command image is written, the voice processor registers the speech, recorded in the voice recording memory, into a voice register file in association with the key image. When an image identical to the registered key image is input, the voice processor reads the speech corresponding to the key image from the voice register file into the voice recording memory, and reproduces the speech from a loudspeaker.

  • Patent number: 5545576
    Abstract: A gate electrode, a semiconductor thin film, a channel protecting film and a photoresist are accumulated on the overall surface of a transparent substrate on which a gate electrode and a gate line are formed. Ultraviolet rays are irradiated through the substrate so that the photoresist and the channel protecting film are self-aligned with respect to the gate electrode and the gate line. A mask is formed on the channel protecting film so as to extend in a direction perpendicular to the channel protecting film. The channel protecting film and the semiconductor thin film are etched using the mask. As a result, the semiconductor thin film and the channel protecting film are patterned without positional deviation so as to have the same width W. Therefore, it is possible to reduce the thin film transistor forming region and the number of steps of the manufacturing process.

  • Patent number: 5546424
    Abstract: A spreading process is performed with a spreading code assigned to each user and a spreading code assigned according to an attribute, and the resultant signal is modulated on the transmitter side. On the receiver side, a transmitted signal, modulated in the above manner, is subjected to a despreading process with the attribute-oriented spreading code from a reception spreading code generator, the resultant signal is subjected to despreading process with the user-specific spreading code from the reception spreading code generator, and those signals which have undergone the despreading processes are demodulated by data demodulators to extract desired information together with a desired signal corresponding to a wide band service. It is therefore possible to simplify the management of the individual users and individual services and facilitate the system design.

  • Patent number: 5546466
    Abstract: When a plurality of effects are simultaneously applied to an input audio signal, a plurality of effect-algorithms each for applying solely an effect to the input signal are stored in a memory, and a plurality of combination-algorithms or combination-data which represent combinations of the effects and orders in which effects are applied to the input audio signal are stored in the memory. When one of the combination-algorithms or the combination-data is selected, effect-algorithms included in the selected combination-algorithm or combination-data are selectively read out from the memory. A program for applying effects in a predetermined combination and order is written by CPU based on the read out effect-algorithms and combination-algorithm or combination-data. Receiving the program, DSP successively applies effects to the input audio signal in accordance with the program.

  • Patent number: 5544091
    Abstract: For input signals f0-f7, by the implementing of signal processing in several stages with bit-serial form, output signals f0-f7 are obtained. For input signals f0-f7, non-two's power approximation proportions of ideal values of fixed coefficient, i.e., cos[.pi.l(2K+1)/2N] are applied. This results in asymmetrical hardware to implement a forward transform mode and an inverse transform mode. Therefore, by adding a circuit element which is employed for a forward transform mode, and by adding a circuit element which is employed for an inverse transform mode, hardware which can deal with both of forward transform and inverse transform is realized.

  • Patent number: 5538920
    Abstract: A semiconductor device has a connection electrode and protective film formed of organic material and covering the connection electrode. An opening is formed in the protective film to expose the connection electrode. A natural oxide layer is etched by argon-based dry etching. The surface layer of the protective film is altered to reduce the insulativity in the dry etching process. After a projection electrode is formed on the connection electrode later, the altered surface layer of the protective film is removed by oxygen-based dry etching. As no altered surface layer remain on the protective film, an adverse affect such as inadequate insulation does not occur.
