摘要： PURPOSE:To select and put plural video signals which differ in aspect ratio together. CONSTITUTION:An image processor 22 selects and puts the video signal (squeeze signal) of 9:16 in aspect ratio from an image source 20A and the video signal of 3:4 in aspect ratio from an image source 20B together and supplies the composite signal to a monitor 24 with a 3:4 aspect ratio. A horizontal expanding circuit 28 cuts a center part except the starting 1/8 period and ending 1/8 period of each horizontal video period out of the output video signal of the image source 20A and expands it to one horizontal video period. The output video signal of the horizontal expanding circuit 28 is a video signal which matches a screen of 3:4 in aspect ratio. A selective composing circuit selects and puts the output video signal of the image source 20B and the video signal from the horizontal expanding circuit 28 together in one.

摘要： PURPOSE:To accurately obtain a battery residue by obtaining an open circuit voltage of the battery from the output voltage of the battery before and after variation in the operating state of a load circuit, and comparing it with data regarding open voltage vs. voltage residual characteristic of the battery. CONSTITUTION:A voltage between terminals of a resistor 18 is digitized by an A/D converter 20 before and after variation in the operation modes of a load circuit 14, input to an operator 22, and multiplied by a predetermined coefficient in the operator 22 to obtain a load terminal voltage V. An open circuit voltage V is obtained by operation from the voltage V of a battery 10 and a load current I therefore. The voltage V is compared with data of open circuit voltage vs. battery residual time obtained by an experiment, stored in a memory 26 to determine the battery residual time.

摘要： PURPOSE:To more accurately decide the residual capacity of a battery by correcting the residual capacity of the battery, which is calculated in accordance with the open-circuit voltage, by the difference between plural open-circuit voltage values detected at different times. CONSTITUTION:A calculating circuit 20 sends a control signal to a measuring circuit 18 to connect a switch 16 to a contact (a) and a contact (b), and currents I1 and I2 flowing to resistances 12 and 14 and inter-terminal voltages V1 and V2 of a battery 10 are measured respectively. The circuit 20 calculates an open- circuit voltage V of the battery 10 in accordance with currents I1 and I2 and voltages V1 and V2. In the case of the voltage V first calculated after the start of a device, its value is stored as a variable VX and is subtracted from the open-circuit voltage V calculated again after a certain time to obtain a variation DELTAV. The circuit 20 obtains the time corresponding to the residual capacity of the battery 10 and displays it on a display device 22, and calculation is terminated when this time is '0', but the voltage V is stored as the variable VX to calculate the voltage V again when it is not '0'. Thus, the obtained residual capacity value is corrected by the difference value of the voltage V to obtain a more accurate residual capacity.

摘要： PURPOSE:To reduce the unevenness of rotation by changing the clock frequency in a digital servo, in a phase where a torque ripple is generated. CONSTITUTION:A driving circuit for a brushless motor 19 is composed if a magnetoresistance element 11 and its FG amplifier 20, an oscillator 13, a frequency divider 14, a counter 15, a D/A converter 16, a compensating filter 17 and a driver 18, and changes a supply current to the motor 19. In this case, a corrective circuit 21 and an A/D converter 26 are also provided and said corrective circuit 21 produces a torque ripple cancel correction signal by a three phase back electromotive force waveform. The output of said corrective circuit 21 is converted into a digital value by said A/D converter 26. Then, where a generated torque is lower than a desired value, the latch output of said counter 15 is latched at a large value and a high voltage is applied to the motor 19 so that a current value increases and the generated torque becomes higher. On the contrary, where said generated torque is higher than said desired value, a service voltage drops and the generated torque lowers too.
