Title: Production of magnetic head
Inventor: KAMEOKA FUMIO
IPC: G11B5/187
Filed: 1990-03-19
Abstract: PURPOSE:To prevent the peeling and burring of ferromagnetic metallic thin films to be generated at the time of forming glass packing grooves and to regulate a gap length with high accuracy by forming the glass packing grooves before the ferromagnetic metallic thin films are formed. CONSTITUTION:Glass 16 is packed into the glass packing grooves 14 which regulate thin-film forming surfaces 15 atop a pair of substrates 7 consisting of a ferromagnetic oxide. The ferromagnetic metallic thin films 3 are deposited on the thin-film forming surfaces 15 and the glass 16. A direct resist 17 is then formed on the ferromagnetic metallic thin films 3 and are etched to remove the ferromagnetic metallic thin films 3 deposited on the glass 16. Nonmagnetic thin films 8 for forming gaps are formed atop a pair of the substrates 7 in succession thereto and a pair of the substrates 7 are glass-bonded to each other in such a manner that the ferromagnetic metallic thin films 3 are butted against each other via the nonmagnetic thin films 8. The peeling and burring of the ferromagnetic metallic thin films at the time of forming the glass packing grooves are prevented in this way and the gap length is regulated with the high accuracy.

Title: Automatic hue control device
Inventor: NAGAO NOBUYA
IPC: H04N9/68
Filed: 1980-05-26
Abstract: PURPOSE:To realize a proper control of hue, by applying a signal EQ to a nonlinear signal processing circuit which varies its characteristics according to the signal EI of a color TV, extracting the output EQ' to give it to a matrix circuit, thus compensating only a color close to the flesh tint not to lower the degree of saturation of other colors. CONSTITUTION:A chrominance subcarrier (a) having the same phase as a burst and a carrier chrominance signal (a) obtain signals EQ and EI throgh a circuit shown in a block diagram. The signal EI is applied directly to a matrix circuit, and the signal EQ is applied to the circuit 9 via a nonlinear signal processing circuit 10 which is installed in place of a conventional attenuator. Thus three color difference signals (c), (d) and (e) are obtained. A nonlinear signal and a linear signal are obtained at the circuit 10 in the case of EI>=EIC and EI<EIC respectively, and the characteristics is varied by the size of signal EI. At the same time, the control range EQC of the signal EIC is also changed by a control signal (f). In such way, a proper compensation is given only the colors within a range approximate to the T axis of the flesh tint, and no compensation is given to the colors outside this ragne. Thus a color reproduction is possible with a color close to a natural state and without lowering the degree of saturation.
