Title: Production of magnetic head
Inventor: ARIGA EIKICHI
IPC: G11B5/127
Filed: 1993-05-24
Abstract: PURPOSE:To prevent warpage in a core half caused by the difference of thermal expansion between a magnetic material and a metal magnetic material in the production method of a magnetic head by which a magnetic gap is formed by joining magnetic core halves comprising a magnetic material with surfaces of metal magnetic material films facing to each other. CONSTITUTION:Metal magnetic films 3, 3a, 4, 4a are formed on both of joining surfaces and back surfaces of core half bodies comprising a metal magnetic material. Glass is molten in the apex part formed on the joining surfaces of the core halves joined and solidified to join the core half bodies. Then the joined body is cut into a specified dimension to obtain a magnetic head product. By this method, expansion of metal magnetic films formed on both surfaces of the core half is balanced when the half body is heated at high temp. to fill the glass, and thereby, warpage harmful for formation of the gap is not produced.

Title: Method for controlling operation of rolling mill
Inventor: SHINTANI SADAHIKO
IPC: B21B1/22
Filed: 1985-07-02
Abstract: PURPOSE:To stabilize rolling or light draft rolling of an extra-thin material and to execute satisfactory rolling by controlling the circumferential speeds of work rolls to different speeds until motor currents attain the values necessary for a stable operation when the motor currents of a rolling mill attain the values to disturb the stability of the operation of the rolling mill. CONSTITUTION:Currents I0, I1 of motors 3, 4 are detected and the rolling is so executed that the circumferential speeds V0, V1 of the work rolls 1, 2 attain a uniform speed when the absolute values of the currents I0, I1 are larger than the set values. One of the rolls 1, 2 is controlled to the low speed and the other to a different speed which is higher than said speed and the rolling is executed at such speeds if the currents I0, I1 are smaller than the set values. The reason thereof lies in that the circumferential speed ratio is small and the driving torque is small in the case of the uniform speed rolling but if the circumferential speed ratio increases in the different speed rolling, the driving torque increases and the currents increase as well. The circumferential speed ratio is therefore changed to the larger value if the detected current values are smaller than the set values. The stable operation is thus assured.

Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a self-supporting cable capable of giving looseness to a cable itself in the case of a connection work. SOLUTION: A wave-shaped deformation is given so as to generate looseness in a cable body member 21, and a supporting line 5 and the cable body member 21 are covered with thermoplastic resin integratedly extruded without deforming the wave shape of the cable body member 21.

Title: Signal processing circuit for charge coupled device
Inventor: AKIYAMA IKUO
IPC: H04N5/335
Filed: 1986-06-20
Abstract: PURPOSE:To obtain a signal processing circuit for a CCD having a large noise- reducing effect by limiting the zone of an output signal from the CCD while clamping the field-through level of the Zone at a fixed potential. CONSTITUTION:When clamping pulses phiC applied to a switch 3 for a soft- clamping circuit 5 are turned ON first, a coupling capacitor 2 is charged at the potential VC of a DC power supply 4. Since a CCD output signal from a buffer amplifier 9 is transmitted to the capacitor 2 through a resistor 1, on the other hand, the CCD output signal receives band limiting in which only a low pass component passes, and the high band component of output amplifying noises in the output signal is damped. CR is selected so that folded noises are minimized within a range in which clamping is applied normally at that time. phiC is turned OFF at the next time, gate pulses phiG applied to a switch 6 for a gate circuit 7 are turned ON in place of phiC, only a CCD output is outputted from the circuit 7, and gains are adjusted by an inversion amplifier 12 through a buffer amplifier 11 and an LPF 8.
