  • Patent number: 5694061
    Abstract: A semiconductor device having at least first and second MIS transistors of a same P or N conductive type. The first MIS transistor has a first data terminal which receives a high potential Vdd, and the second MIS transistor has a first data terminal which receives a low potential GND lower than the high potential Vdd. An output terminal is coupled to second data terminals of the first and second MIS transistors. A first input terminal is connected to a gate of the first MIS transistor for supplying a non-inverted signal. A second input terminal is directly connected to a gate of one of the first and second MIS transistors for supplying an inverted signal having a reverse polarity to the non-inverted signal and which is synchronized with the non-inverted signal. An output voltage compensating circuit is connected between one of (i) the output terminal and the first input terminal and (ii) the output terminal and the second input terminal.

  • Patent number: 5691493
    Abstract: A main CPU and a sub CPU take share of executing a tone generating process to generate multiple tone signals on a real-time basis without using an exclusive tone generator. The main CPU and sub CPU are formed on a one-chip LSI, thus facilitating realization of a compact electronic musical instrument. According to another structure, the main CPU executes tone generation while the sub CPU performs an effect process, thereby permitting a one-chip LSI to generate an effect-added musical tone.

  • Patent number: 5689352
    Abstract: A plurality of conductive lines are formed on a lower base plate. One surface of the lower base plate is divided into a first portion which is to be formed into a lower substrate, and a second portion. The first portion includes a first area which is to be covered with an upper substrate, and a second area. The conductive lines are extended from the first area of the first portion to the second portion through the second area of the first portion. A connecting pattern is formed on the second portion, and is connected to each of the conductive lines. Thereafter, an orientation film is formed on the first area of the first portion. Then, the surface of an orientation film is rubbed in an orientation process. During the orientation process, electric charges which are generated in each of the conductive lines by friction, flow to the connecting pattern immediately. Therefore, the conductive lines and the orientation film are protected from the electric charges, and damage is avoided.

  • Patent number: 5687386
    Abstract: A character input apparatus contains a ROM that stores the character change pattern for each character according to where the character is in a string of characters, and a character reader for reading the characters before and after the entered character. When a character is entered from an input unit, the characters before and after the entered character are read by the character reader, and the change patterns corresponding to the entered character and the characters before and after the entered character are read from the ROM. This makes it possible to enter such concatenated characters as those written in one stroke, and further enter characters in a language where the form of each character changes according to the preceding and succeeding characters.

  • Patent number: 5682504
    Abstract: A printing apparatus is provided with a thermal head which has a plurality of heatable elements disposed in a line and divided into plural groups. A control unit controls the plural groups of heatable elements in accordance with printing data to generate heat to thermal-transfer ink of an ink ribbon onto a label tape, thereby printing the printing data on the label tape. A boundary heatable element within one group of heatable elements which is disposed adjacently to other group of heatable elements is driven in accordance with the printing data when the other group of heatable elements are driven to generate heat. The boundary heatable element generates heat twice to prints data twice on the label tape at a portion corresponding to the boundary between two groups of heatable elements, there by printing data on the portion with higher printing intensity.

  • Patent number: 5680184
    Abstract: A pair of polarizing plates are arranged on both the sides of a liquid crystal cell in which liquid crystal molecules are aligned to be twisted, and two biaxial retardation plates serving as color adjusting optical elements are arranged between one of the polarizing plates and the liquid crystal cell. The biaxial retardation plates satisfyn.sub.X >n.sub.Z >nywhere n.sub.X, n.sub.y, and n.sub.Z are refractive indexes in a direction in which a maximum refractive index is obtained on the plane of the biaxial retardation plates, a direction perpendicular to the direction in which the maximum refractive index is obtained on the plane, and a direction of thickness, respectively. The positions of maximum refractive index directions serving as the phase delay axes of the biaxial retardation plates are set to obtain a display color having a desired hue.

  • Patent number: 5680378
    Abstract: A CPU edits audio data stored in a hard disk by referring to an event address table. The event address table serves to store the ID information of each event and the storage position of each event on the hard disk. Pieces of ID information corresponding to the order of reproduction of the events are arranged and stored in a control track. In the reproduction mode, the storage position of each event on the hard disk is detected from the ID information arranged/stored in the control track, and audio data is read out from the hard disk in a desired order of the events.

  • Patent number: 5677999
    Abstract: Plural types of fixed format data for printing on a label tape are previously stored in a ROM in a label printer. The label printer displays a menu for selecting a fixed format on a display section. A user operates a key input section to select a fixed format and then input character data. The input character data is printed on a label tape in accordance with a format based on selected fixed format data. Therefore, the printing apparatus can easily input data and prepare elaborate label tapes.

  • Patent number: 5672837
    Abstract: Measures each contain plural event data, which are memorized in an arrangement of SNG-SONG. 1024 measures (the first measure to 1023-th measure) in each music or in each track of the music are grouped into 8 measure blocks. Leading event data of 8 measure blocks each containing 128 measures are memorized in an arrangement of SNG-BAR-PTR. Element numbers of leading event data of respective 128 measures contained in each measure block are memorized in an arrangement of SNG-BAR-TBL. For example, increment or decrement of a point value of the measure block in the arrangement of SNG-BAR-TBL or the measure in the arrangement of SNG-BAR-PTR allows a fast forward reproduction and/or a fast rewind reproduction.

  • Patent number: 5668784
    Abstract: A pair of band holding members are attached by joint pins to band attachment portions of a watch case formed at positions of 12 o'clock and 6 o'clock of a dial in the watch case. The band holding members extend obliquely and outwardly from a back surface of the watch case in a direction opposite to a front surface thereof. A watch band insertion slot is formed in each of the holding members to extend from a first position which is positioned at or away from the back surface of the watch case to a second deposition which is positioned further away from the back surface of the watch case than the first positions and to open at the first and second positions. A watch band consisting of one band piece is passed through the watch band insertion slots of the band holding members so that the watch band projects its both end portions from the openings of the second positions of the insertion slots of the band holding members toward outsides of the holding members and extends along the back surface of the watch case.
