An electronic musical instrument with playback of background tones and generation of key-on phrase tones, in which a simple adlib play can be performed while a user is singing using a microphone or as an interlude without requiring high-grade techniques is disclosed.The electronic instrument includes an instrument main body (1) having a microphone (5) and a plurality of key pads (6), a section for playing back stored background tones of a song, a memory (21) for storing note pattern data for a plurality of phrases each consisting of a series of a plurality of key-on phrases in correspondence with the plurality of key pads, and a tone generator (20) for reading out the note pattern data of the corresponding phrase in response to an operation of the key pad (6), and forming tone generation signals. The output from the microphone, the playback signals of the background tones, and the tone generation signals of the phrase are supplied to a loudspeaker (11). Parallel to the playback background tones, the prestored phases can be read out and played back as needed upon operation of the key pads. A singer sings a selected song while listening to the background tones of the song. Upon combination of some phrases, a simple adlib play is performed, and a joyful performance can be made.

An image collating center has a communication unit, a processing unit, and a memory unit. The processing unit accesses a geographic information database through a communication network, extracts appropriate geographic information from the geographic information database based on a picked-up image and additional information transmitted from an image provider, and generates a simulated image assumed to be viewed from the image provider. Further, the image collating center estimates the image pickup position and the image pickup attitude of the image provider through collating the simulated image with the picked-up image and returns the estimated image pickup position and image pickup attitude of the image provider to the image provider through the communication network.

摘要:
This invention discloses an electronic musical instrument, which shifts the tone pitches of a series of externally input voice signals in real time, and outputs the shifted voice signals from a loudspeaker. Data for shifting the tone pitches of voice signals is pre-programmed in a memory circuit as music piece data. Every time a user operates an operation switch, the music piece data is sequentially read out, and the tone pitches of voice signals input from a microphone are shifted by a tone pitch converter. The shifted voice signals are output from a loudspeaker in real time. The input voice signals can be shifted to a melody corresponding to the music piece data.
摘要:
In a method of processing a sealing surface of a casting to eliminate casting defects on or in the vicinity of the sealing surface, each of abrasive grains constituting a grindstone has a flat face formed on its distal end. The sealing surface of the casting is ground by the grindstone while the flat face of each abrasive grain is held parallel to the sealing surface of the casting. Consequently, a plastic flow layer is formed on the sealing surface of the casting. Blowholes present within a predetermined range of depth of the casting from the sealing surface are collapsed as the result of formation of the plastic flow layer.

An electronic keyboard or similar electronic musical instrument having an automatic rhythm playing function and an ad-libbing function. The instrument includes keys to which an ad-libbing function is assigned. When one presses any of the ad-libbing keys on the keyboard, the instrument allows the operator to feel as if the operator were performing an ad-lib. Various kinds of ad lib plays are available by looping note data representative of a single melody or by transforming the note data to a plurality of melodies by chord detection.

A single-chip microcomputer is disclosed, which comprises a central processing unit including a programmable counter for storing address data for accessing a first memory and performing operations and control, a register for setting address data of a second memory and a coincidence circuit. When the contents of the register and programmable counter coincide, the coincidence circuit provides an instruction to the central processing unit. Thus, the central processing unit accesses an address of the second memory in lieu of an address of the first memory, in which an undesired instruction in stored, according to data in the first memory. Subsequently, the second memory address is accessed in lieu of the first memory address with the undesired instruction therein.
