Abstract: A method of executing communication programs in a modem apparatus. A plurality of communication programs used to perform data communication or facsimile communication are stored in an internal memory space (e.g., ROM) in a processor after they have been compressed. A communication program to be executed in ROM is decompressed and developed in a work area external to the processor (e.g., RAM). The developed communication program is then executed by the processor. The data decompression is performed according to an exclusive program decompression program or a program in the communication programs which is adapted to provide a data decompression function.

Abstract: A communication card and the structure of a jack therefor. The end face of the card is provided with a slit-like aperture. Into the aperture there is inserted a base plate having a thickness smaller than the width of the aperture so as to allow insertion into the interior of the card and removal from the card. The base plate is provided with a notch directed to the outside when viewed from the card. The notch passes through the base plate in the direction of its thickness. The jack is formed by utilizing this notch. The plug, on the other hand, is of a rectangular parellelpiped shape and is electrically coupled to a cord. The inner surface of the notch is configured so as to be able to receive the plug. When the plug is inserted, the notch receives and holds the plug. At that time, the notch receives and holds the plug in such a manner that the direction of the longest edge among the edges of the plug, or the extending direction of the cord is parallel to the major planes of the card.

Abstract: A convergence measurement apparatus for a color cathode-ray tube is capable of high precision convergence measurement by elimination of luminance omission portions occurring in the screen. A dot pattern displayed on a color cathode-ray tube is picked up by an image pickup camera and is stored in an image memory. A signal movement amount control unit is arranged to move a beam spot of the dot pattern displayed on the cathode-ray tube by a predetermined pitch in a horizontal or vertical direction. Corresponding dot pattern shifting occurs to sequentially record images of discrete colors for a more accurate measure of convergence. For example, if a gap between adjacent phosphor elements of one color (for example red) is defined as one pitch, three sequential red dot patterns can be each shifted by 1/3 of a pitch and thereafter picked up and stored in the image memory of dot pattern data.

Abstract: A DQPSK delay detection circuit is provided that can securely reproduce stable clock signal. An absolute value circuit ABS(14) calculates an absolute value of I signal. An absolute value circuit ABS(15) calculates an absolute value of Q signal. Subtraction circuit(16) generates a P signal according to the difference between the absolute values of I signal and Q signal. Zero-cross detection circuit(11) detects zero-cross timing of the P signal to input it as a timing signal to the DPLL(64). The zero-cross timing of the P signal can be detected even when the data pattern of I or Q signal makes it impossible to detect the zero-cross timing from I and Q signal. Because the zero-cross timing of the P signal has a variation less than that of the zero-cross timing determined from I or Q signal, it is becomes possible to reproduce stable clock signals and in turn reliability of data demodulation can be improved.

Abstract: In a rotor which is rotated for adjusting capacitance provided by a variable capacitor, a portion for receiving a tool for rotating the same is defined by a through-hole. Thus, it is possible to protect the rotor from application of a pressing force from the tool, thereby suppressing change of a clearance between the rotor and a stator. Consequently, it is possible to stabilize the capacitance as the capacitor is being adjusted, as well as to reduce setting drift that causes the capacitance as adjusted disadvantageously to change when the tool is separated from the rotor.
