Abstract: PURPOSE:To improve the S/N of the restored pictures by obtaining the least value to minimize the sum total of errors obtained among all picture elements for each block in a quantizing step and using the data to quantize the source data. CONSTITUTION:A quantizing circuit 7 performs an encoding job to the source data (x) stored in a block consisting of the prescribed number of picture elements in accordance with a dynamic range. The encoding data Q and the data (x) are supplied to a correction circuit 9. Then a quantizing step DELTA' or the dynamic range and the minimum value MIN' are set so that the square sum of the errors of the decoded value and the data (x) which are calculated based on the data Q and the step DELTA' set newly is minimized in terms of all picture elements within the block. Based on those set values, the data (x) is encoded by a quantizing circuit 16 in accordance with the dynamic range. Therefore it is possible to reduce the sum total of distortion degrees of all picture elements in the block and to improve the S/N of the restored pictures.

Title: Electric discharge machining power source
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1988-02-04
Abstract: PURPOSE:To obtain a discharge current having a high peak value by providing a circuit which turns on a switching element and feeds back a charged voltage to a smoothing capacitor via impedence when the charged voltage of a high voltage smoothing capacitor gets higher than a defined level. CONSTITUTION:By turning on transistors T1, T2, a source voltage E is applied between a workpiece W and an electrode P and, as electric discharge is generated between the workpiece W and the electrode P, a discharging current is linearly increased in accordance with the values of the source voltage E and the inductances L1, L2 in an electric discharge circuit. On the other hand, as the transistors T1, T2 are turned off, the energy stored in the inductances L1, L2 is fed back to a high voltage smoothing capacitor C2 through a circuit for feeding back to the capacitor C2. However, if the voltage of this capacitor C2 is kept higher than the source voltage E, the rise of the feedback current becomes steep reducing the width of the feedback current. Thereby, the pulse width of the discharge current gets small and, as a result, a discharge current having a higher peak value can be obtained with the same pulse current width.

IPC: H03G3/32
Filed: 1982-02-15
Abstract: PURPOSE:To prevent the generation of an eary rasping noise due to a BBD securely, by driving a muting circuit through a muting switch when a microphone is not in use and cutting off the output signal of the BBD. CONSTITUTION:When a microphone switch 4 is turned on, an interlocking muting switch 11 is also turned on to ground the base of the muting transistor (TR)13 of the muting circuit 12, which is then not in operation. Therefore, the output signal of the BBD6 is applied, as it is, to the 1st mixing circuit 7 through a variable resistance 16. When the micropnone switch 16 is turned off, the interlocking muting switch 11 is also turned off, so a prescribed bias is applied to the base of the muting TR13, which turns on. Consequently, a noise output of the BBD6 is grounded through the variable resistance 16 and the collector-emitter path of the TR13 and not applied to the 1st mixing circuit 7, so the noise originating from to the BBD6 is outputted from a speaker 10.

The composite current of the currents iC and iL is flowed to the input current iS by this operation. In this manner, the input power factor can be improved, thereby simplifying the circuit arrangement.
