Title: Magnetic recording and reproducing head
Inventor: MATSUDA NOBUHIDE
IPC: G11B5/127
Filed: 1982-05-11
Abstract: PURPOSE:To extract only an effective signal containing the reduced noises, by providing plural magnetic poles having windings around them in opposition to a vertically magnetized recording medium and adding a differential amplifier which performs magnetic recording/reproducing with the 1st magnetic pole and then obtains the output difference between the 1st magnetic pole and another. CONSTITUTION:For instance, a main magnetic pole 2 is set at the side of a magnetic material 4 of a vertically magnetized recording medium 1, and auxiliary magnetic poles 31 and 32 having even characteristics are provided opposite to the pole 2. In this case, the pole 31 is set opposite to the pole 2 and the polse 32 is set close to the pole 31. The outputs of the poles 31 and 32 are fed to a differential amplifier 5. The reproduced signal of a recorded signal emerges only at the pole 31. When an external magnetic field has a fluctuation, the induced voltage due to this fluctuation emerges both at poles 31 and 32. Then only an effective signal containing the reduced noises is obtained by a differential amplifier 5. It is also effective to use two main magnetic poles instead of two auxiliary magnetic poles and to extract a difference signal out of the windings of main magnetic poles 21 and 22.

Abstract: PURPOSE:To stabilize the characteristics by preventing the generation of air gaps in the titled device by a method wherein a hole is bored in the Si oxide film on the surface of a substrate, and the hole of the Si film is enlarged after forming a recess in the exposed substrate surface. CONSTITUTION:An SiO2 film 12 is deposited on the surface of the GaAs substrate 11 by CVD. Next, the hole 13 is bored in the film 12, thus exposing the surface of the substrate 11, and thereafter the recess 131 is formed by removing by etching the exposed surface of the substrate 11. Then, the hole 13 is enlarged concentrically, resulting in the formation of a hole in such a manner that the surface of the substrate 11 so exposes as to surround the recess 131 in ring form. A Ta layer 14 and an Au layer 15 are formed by vapor deposition on the recess 131, the surface exposed part 11a of the substrate 11, and the SiO2 film in the periphery. The Au layer 15 is removed by etching by leaving the electrode part 16, and the Ta layer 14 other than at the electrode part 16 is removed with the Au layer at said part 16. An reacting layer 18 is formed by heat treatment.

Abstract: PURPOSE: To make lateral visual fields and back visual field visible respectively alternately selectively by connecting the lens-barrel of the lateral checker near the eyepiece portion of the lens-barrel of the oscillating back checker and providing a reflecting mirror which permits opening and closing through remote operation to its connection part.  
     CONSTITUTION: At the time of lateral checking, the rays of a wide visual field taken in through a fish-eye lens 18 are reflected by a reflecting mirror 20, pass through a lens barrel 22, and are reflected by a reflecting mirror 24 which is held open by 45° downward then by a reflecting mirror 16, after which they slightly reflect irregularly on a convex lens 17 and enter the driver's visual field. At the time of oscillating back checking, the reflecting mirror 24 is closed upward like the dotted lines and a wire 8 is pulled to oscillate the oscillating barrel 11. At this time, the rays taken in through the fish-eye lens 1 bypass the underside of the reflecting mirror 24 and reach the convex lens 17 and therefore the driver is able to view the back visual field. By opening and closing the reflecting mirror 24 by an electromagnet 29 through remote operation in this way, the lateral visual fields and back visual field become respectively alternately selectable, thus safety may be assured.

The inputted analysis conditions are stored in the memory in the control part 7. The setting part 3 is removed from the body part 2 after the analysis conditions are set. Since the analysis conditions are thereby stored in the memory of the control part 7 even after the setting part is removed, the analysis processing is thereafter executed according to the analysis conditions. Since the setting part 3 is removed from the body part 2 in this case, the change of the conditions by the erroneous key operation is obviated and a malfunction is prevented.
