Abstract: In a video reproducing apparatus, operating devices and recording devices are connected with a simple structure to record game information while operating the game, and a plurality of small capacity of external secondary memory means can be used as a large capacity of external secondary memory means. The main body of the video game machine is connected to a plurality of the operating devices with a serial interface so that serial data is communicated bidirectionally in accordance with a predetermined communication procedure while at the same time connecting recording devices to the serial interface respectively corresponding to a plurality of operating devices to allow the main body of the game machine to write predetermined data into and read it from recording devices in accordance with a communication procedure.

Abstract: A electronic keyboard instrument for producing an artificial sound, including a plurality of keys; waveform-forming structure for generating a signal indicative of a waveform of an artificial sound corresponding to one of the keys, when the one of the keys is depressed; at least one operating element; detecting structure for detecting whether or not the at least one operating element is being operated; and waveform-modifying structure for modifying the signal indicative of the wave form depending on results of detection by the detecting structure, the waveform-modifying structure including envelope-determining structure for determining an envelope of the wave form of the artificial sound, and envelope-modifying structure for outputting a modification value used in changing an output from the envelope-determining structure depending on results of detection by the detecting structure.

Abstract: A PCM signal editing apparatus with functions of storing in memories the edit-point proximate sample data of a first PCM audio signal reproduced from a first recording medium and that of a second PCM audio signal reproduced from a second recording medium, then reading out such sample data of the PCM audio signals at a desired speed from the memories respectively in a manner to attain a coincidence of the edit points, and cross-fading the signals at the edit-in point or edit-out point in a cross-fade time conforming with the read-out speed, thereby performing a short-time insert editing operation with high efficiency and sufficient certainty. Furthermore, the apparatus is so contrived that the editing conditions proximate to the edit points of the PCM audio signals can be aurally perceived with accuracy, and the access states of the memories are displayed by bar graphs to consequently render the editing state visually recognizable.

Abstract: According to the present invention, a fish growth hormone was isolated from an organ culture broth of the pituitary gland of eels, and further a recombinant DNA incorporated with a DNA coding for the eel growth hormone polypeptide and a microorganism containing the recombinant DNA were obtained. They can be used for mass production of an eel growth hormone.
