Abstract: PROBLEM TO BE SOLVED: To reduce a data quantity obtained as a result of image coding. SOLUTION: A texture area separate circuit 36 detects a texture area being a closed area where a degree of a change in a picture element is small. Then a characteristic amount calculation circuit 40 calculates an average value (hereinafter called activity) of absolute values of orthogonal transformation coefficients in each texture area, a quantization map generating circuit 41 decides the quantization step size for the orthogonal transformation coefficient in each texture area based on the activity. Then a quantization device 42 conducts quantization based on the quantization step size.

Title: Antenna adjustment system
Inventor: MORIZAKI SHOJI
IPC: H04B1/40
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To obtain an antenna adjustment system by which an operator can select an audible frequency band that belongs to a sound frequency band easily discriminated by an operator. SOLUTION: In the case of adjusting the direction of a reception antenna to maximize a reception input electric field of a radio receiver 2, the strength of the reception input electric field is discriminated depending on the level of an AGC signal of the radio receiver 2. A frequency oscillator 3 receiving the AGC signal provides an output of an audible tone and an operator discriminates the strength of the reception input electric field depending on a pitch of the audible tone (when the electric field is strong, the pitch of the audible tone is high or low).  Since this method adopts discrimination depending on the pitch of the tone, it is not required for the operator to observe an indication of an electric field strength meter, for example, and the operator adjusting the direction of antenna need not divert the sight from the working point and then one-man operations is attained more safely. Furthermore, the frequency oscillator 3 of the antenna adjustment system is provided with a level converter 3-1 to allow the operator to select a range, which is easily discriminated by the operator.

Abstract: PROBLEM TO BE SOLVED: To prevent a boss from damaging even when excessive force is given to a gear which is meshed with a rack gear to transmit driving force of a motor to a pickup by elastically holding a bearing for holding the gear. SOLUTION: When a carriage motor 8 is driven to rotate the gear 15 in the direction of an arrow work F, force Fo is worked at the contact point between the gear 15 and the rack gear 7. Since the rack gear 7 is already positioned in a limit of a range of sliding the pickup, this position is not changed, and force -Fo is given to the gear 15 due to reaction. Therefore, the gear 15 which is provided on an elastic holding member 17 is given force in the direction of unmeshing from the rack gear 7 to gradually increase the driving force of the carriage motor 8, and when the driving force exceeds component force Fx , the center of a rotary axis of the gear 15 is displaced, and the gear 15 is unmeshed from the rack gear 7 to run idle. Consequently, a shaft and a boss for supporting each individual gear are not bent.
