Abstract: A microcomputer based music apparatus allows a user to gain efficient access to a desired chord progression (CP). To this end, the apparatus includes a chord progression database (CPDB) containing a large collection of practical CPs with various kinds of style and harmonic rhythm. A database localizing manager provides a localized virtual space of CPs preselected from CPDB in accordance with the user's musical tastes and intentions. To help the user think of a melody and its harmonization in an integrated mental process, a suitability testing feature evaluates suitability between a CP (from CPDB) and a melody (supplied from the user) based on stored melody pattern rules. A music editor electronically manages (edits) structures of an intended music piece and provides a desired chain of phrases (each including attributes, CP and melody) in accordance with user's commands to construct a desired music piece, thus aiding the user's music composing activities.

Abstract: In a compass, the direction of the geomagnetism is detected by magnetic sensors and an azimuth detector, and data on the direction of the geomagnetism is supplied to a controller. A ROM stores declination data representing the angle formed between the direction of the geomagnetism and the direction of the geographic meridian. The data on the direction of the geomagnetism is corrected in accordance with the declination data stored in the ROM, to thereby obtain geographical direction data. This geographical direction data is displayed on a display device. In this manner, the compass enables the user to easily know a true direction.

Abstract: In a compact electronic appliance having a display unit, a size of the display unit is stored by specifying, for example, a line number and a column number for a screen display. A judgment is made whether or not the inputted character position exceeds the line number and column number while inputting display information on the display unit. An external storage medium, such as a so-called IC card, stores the display information, monitors a judgment result made by the compact electronic appliance, and controls a transfer of the display information in accordance with the judgment result. Even when the display information is applied to screen to different sizes the display information can, nevertheless, be properly displayed.

Abstract: A resin band is formed by molding a first resin member by injection molding to cover a net member excluding its periphery, and by molding a second resin member by injection molding to cover a periphery of the net member exposed from the first resin member. In the resin band formed in this manner, the adhesion strength of the first and second resin members is increased by the net member, and the resin band can be colored in two colors by changing the colors of the first and second resin members.

Abstract: When a start signal is supplied from a processing unit, a variable-length processing unit reads out variable-length data stored in a memory unit, executes an operation instructed by instruction information stored in an instruction memory, and outputs an operation end signal to the processing unit when the operation is ended. When the processing unit receives the operation end signal, it outputs an operation result obtained by the variable-length processing means to other devices.

Abstract: First processing means designates a plurality of individually accessible memory blocks of memory means in a predetermined order and performs processing thereon block by block. Second processing means sequentially process those blocks, block by block, which have already been processed by the first processing means.

Abstract: A compact calculator includes a matrix type display unit and executes a graphic representation of a functional formula. When both the functional formula and an integral range are inputted as information about a definite integral, a judgement is done whether or not an X-value increased while forming a graphic representation is located with the integral range. If this X-value is present within the integral range, then the pixels from the coordinate point (X,Y) to an X-axis are turned on. Thus, the integral range is graphically represented under the above-described process operation.

Abstract: An electrostatic recording apparatus includes a developing agent carrying member having a surface for carrying a developing agent thereon. A plurality of recording electrodes are arranged on the surface of the developing agent carrying member in parallel to each other at a predetermined gap while being electrically insulated from each other. An electrode cylinder is arranged to oppose the plurality of recording electrodes at a predetermined gap. A developing agent convey section conveys the developing agent such that a circulating convey path is formed along the surface of the developing agent carrying member. A voltage control section outputs a control signal including recording data. A recording electrode drive section is provided inside a space defined by the circulating convey path.

Abstract: An astronomical data indicating device is provided with a memory for storing location data representing a location on the earth. In the present device, before calculation of astronomical data such as hour angle data of moon and moon phase data, at first hour angle data and moon phase data for Greenwich Mean Time are calculated regardless of the place where the present device is used, and then hour angle data and moon phase data at the place where the present device is used are calculated. Therefore, the calculation process is performed in a very simple manner.

Abstract: An electronic musical instrument has a tone generation mode selecting switch capable of selecting a tone generation mode associated with an arbitrary one of a keyboard instrument play mode, a stringed instrument play mode and a wind instrument play mode, and a CPU for controlling the tone generation mode for a tone generator in accordance with the selection. This electronic musical instrument serving as a so-called tone generator module, can be driven by a MIDI signal supplied to a MIDI circuit from an external unit.

Abstract: A table memory is provided for selecting types of files to be updated in accordance with identification codes designating types of transactions. When a transaction occurs, the corresponding transaction record and the identification code indicating the type of transaction are generated. Data from the table memory is retrieved in accordance with the identification code to select all the files to be updated. The selected files are sequentially updated in accordance with the transaction record.

Abstract: A music interpreter apparatus automatically interprets a notational music composition (written or printed music), which is abstract and incomplete to some extent, to provide its performance realization information which is specific and complete. The apparatus includes a score memory, an interpreter and a performance memory. The score memory stores a coded music notational symbol string representing a written music composition. The interpreter reads and interprets the coded music notational string based on an artificial intelligence simulating knowledge and experience of a human music interpreter or performer to provide a performance symbol string specifying the performance realization and containing played pitch, note-on time, duration and loudness parameters of specified values with respect to each note in the music composition. The resultant performance symbol string is stored into the performance memory.

The shutter plate is moved to a first position, in which only one of two types of data is exposed, when the above described one data is displayed on the display panel, and is moved to a second position, in which only the other data is exposed so that any not-displayed portions in the display panel is not exposed, when the other data is displayed on the display panel, the two types of data being different from each other in the number of displaying digits for displaying them.

Abstract: A voice input to a microphone is converted by an A/D converter to a digital signal which is then delivered to a DSP, which extracts the notes of the input voice for determining same. The processing by the DSP includes bandpass filtering with a frequency corresponding to each note as the central frequency. A plurality of notes is processed on a time divisional basis to determine their respective notes. A new musical sound electronically corresponding to one or more notes extracted as the result of the note detection is then generated on a real time basis.
