Filed: 1986-03-27
Abstract: PURPOSE:To obtain a magnetic head with an excellent magnetic characteristic at a high yield by forming a magnetic layer by an ion etching method using a batch twice and selectively removing a mask remaining after the 1st etching ends. CONSTITUTION:A magnetic thin film 6 is built up on an insulating layer 4 formed on a conductive layer 3. Next a resist pattern 7 in the desired shape of a magnetic layer is formed on the film 6, which is ion-etched. In that case it is etched by half its thickness. Then a resist pattern 8 is again patterned. In the consecutive ion etching, the resist pattern 8 is patterned so that a part around the gap part of the magnetic layer cannot be thin compared with other parts. The film 6 is ion-etched to form an upper magnetic layer 6. Such an inexpensive, high reliability magnetic head can be obtained at a high yield that employs a resist as an insulating layer and has a magnetic layer with an excellent magnetic characteristic.

Filed: 1995-03-28
Abstract: PURPOSE: To prevent the transmission of the service channel(SC) signal in a noise state at not only the time of the step-out of a reproduction carrier wave but also the time of the input disconnection of a doubly modulated signal. CONSTITUTION: An automatic gain control amplifier circuit 1 performs AGC amplification for the doubly modulated signal a of a main signal and an SC signal and outputs a control signal f when the disconnection of a doubly modulated signal b is detected.

When a carrier wave asynchronization detection circuit 6 detects the asynchronization of the reproduction wave g from the VCO control signal f, the circuit 6 generates a step-out signal i.  An SC signal reproduction circuit 7 reproduces an SC signal h from the VCO control signal f but when the circuit 7 receives a control signal j or the step-out signal i, the circuit stops the transmission of the SC signal h.

IPC: G03F7/004
Filed: 1988-03-25
Abstract: PURPOSE:To obtain the inexpensive resin composition superior in antistatic effect and the light shielding property by incorporating an ethylenic copolymer resin as a resin composition, a coupling agent, an aluminium filler, a carbon black and an antioxidant in the resin composition, in specified amount respectively. CONSTITUTION:The resin composition contains >=20wt.% of the ethylenic copolymer resin.
