Title: Multielement magnetic head
Inventor: INCHI TOSHIO
IPC: G11B5/10
Filed: 1981-08-28
Abstract: PURPOSE:To eliminate the azimuth loss and to improve the reproduction characteristics, by forming a recording head of a metallic material and a reproducing head of a ferrite material into a front core via an SiO2 film with a nonmagnetic block used to a rear core and unifying these front and rear cores into a body. CONSTITUTION:The SiO2 films 1a and 2a are vapor deposited to a recording front core block 1 of a ''Sendust  '' material and a reproducing front core block 2 of a ferrite material. Both cores 1 and 2 are adhered to each other, and grooves 1b and 2b are formed. The thickness of the films 1a and 2a are set <=2mm. and identical with the space between the recording working gaps. Grooves 3a and 3b are cut to a nonmagnetic block 3 and then unified via a center piece 4 to obtain a front block matter 5. The grooves 5a and 5b plus front shielding plates 9 and 10 are provided to the matter 5. Then the block matter 5 is sliced to obtain a front chip 11. Thus the recording side is separated from the reproducing side via a groove 8. As a result, the azimuth loss is reduced and the deterioration can be prevented for the frequency properties of the recording and reproducing characteristics.

Title: Picture data compression processing method
Inventor: ITO WATARU
IPC: H04N19/196
Filed: 1993-06-04
Abstract: PURPOSE:To improve data compressibility while maintaining the picture quality of the important part of pictures by raising a bit number at the time of performing quantization for the highly important part of an object in the pictures and lowering the bit number for the part not so important. CONSTITUTION:Wavelet transformation is repeated N times to an original picture data Sorg and wavelet transformation coefficient signals WW0-WWN, WV0-WVN, VW0-VWN and VVN are obtained. Picture element numbers in respective main and sub directions are (1/2)N for the coefficient signals compared to the original picture data Sorg. The pictures indicated by the respective transformation coefficient signals WVi, VWi and WWi are the ones for which the source pictures are reduced and labeling executed to the coefficient signal WWN corresponds to the respective transformation coefficient signals as well. Thus, at the time of the quantization of the transformation coefficient signals, the bit number of the quantization is changed corresponding to the result of the labeling. Then, for the respective transformation coefficient signals, the picture quality is maintained by raising the bit number for the important part, the bit number is lowered for the unimportant part and the overall compressibility is improved.

Title: Circuit for detecting polarity inversion
Inventor: ENOMOTO SADAICHI
IPC: H04M1/00
Filed: 1984-06-29
Abstract: PURPOSE:To detect the polarity inversion independently of the polarity before trunk line closing by detecting the polarity from a voltage of a trunk line when the voltage of the said line is a prescribed value or over before the DC circuit of a telephone set is closed and from the voltage extracted from a trunk line current when the voltage after the closing of DC circuit is lowered. CONSTITUTION:In case of outgoing, contacts k1, k2 are thrown to the position of trunk lines 5, 6 before the closing of the DC circuit 4 of the telephone set and a polarity inversion detecting section 2 detects the polarity of the voltage and stores it only when a trunk line voltage supervisory section 7 detects that a trunk line voltage is a prescribed value or over. When the voltage is a prescribe value or below, the supervisory section 7 inhibits the said operation, and the contacts k1, k2 are restored. Then, after a dial signal is transmitted from a dial a sender section 1, contacts l1, l2 are opened, hook switches h1, h2 are closed and the contacts k1, k2 are thrown to the position of an inverting current detecting section 3. Then the voltage of the polarity in response to the direction of the trunk line current flowing to the detection section 3 is fed to the detection section 2. The detection section 2 compares the polarity of the trunk line detected and stored before the closing of the circuit 4 with the polarity of the voltage fed from the detection section 3 to detect the polarity inversion.
