Title: Recording/reproducing device
Inventor: MASUOKA NOBUO
IPC: G11B5/56
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To enable securing head contact performance without injuring head life by displacing a gap position to the position extremely enlarging contact force in a magnetic head part. SOLUTION: A magnetic head 1 is fixed to a head base 2, and the head base 2 is attached to an upper drum 4 by an attaching screw 5. At this point, the head base 2 is made freely rotatable around the screw 5. The head base 2 is rotation displaced by displacing a head attitude control member 3. The top 1b and the gap 1a of the magnetic head 1 coincide nearly with each other. When the head base 2 is rotate-displaced, the position of the top 1b isn't changed, and only the position of the gap 1a is displaced in the left direction. In such a manner, the center of rotation of the head base 2 is made coincide with the center of the top shape of the head 1 so that the position of the top of the magnetic head 1 and a projection amount from the upper drum 4 surface aren't changed by rotation displacing the base 2.

Title: Magnetic head
Inventor: TERAI KATSUYA
IPC: G11B5/60
Filed: 1993-07-27
Abstract: PURPOSE:To enable balance winding and to lower an inductance L by providing the magnetic head with a laminated magnetic core chip having a winding window, of which the leading side end face is joined to a groove-forming surface for winding of a slider body. CONSTITUTION:This magnetic head is composed of a slider body 7 having a groove 6 for winding on the end face and a laminated core chip 1 consisting of a I type core 3 and C type core 4 and having a winding window 5, of which the leading side end face is joined to the surface for forming the groove 6 for winding of the slider body 7. The magnetic core chip 1 constitutes the nucleus of the magnetic head and the recording and reproducing to and from a medium are executed by the magnetic gap 9 in the operation of the magnetic head. The medium is floated by rotation of rails 10, 11, 12, 13. Since the area of magnetic metallic films 2 is extremely smaller than heretofore, the L is diminished. The winding window is newly formed on the slider body 7 in addition to the winding window 5 of the laminated magnetic core chip 1 and, therefore, the winding on both of the I type core 3 side and the C type core 4 side, i.e., the balance winding, is made possible and further the decrease in L is made possible.

Title: A/d converter with offset voltage correcting function
Inventor: ARATA KATSUTOSHI
IPC: H03M1/06
Filed: 1993-07-27
Abstract: PURPOSE:To automatically correct an offset voltage in a moment regardless of the abrupt temperature change or the supply voltage variance by supplying the earth potential to one channel and taking the subtraction output between this potential and the analog input signal to the other channel as a digital output signal. CONSTITUTION:An input signal to be essentially digitized is supplied to an R-channel analog input R-IN, and the earth potential is supplied to the other L-channel analog input L-IN. Digital output signals of these two channels are inputted to a digital subtractor 2 and are subjected to subtraction processing, and the substraction output is led out as an essential A/D converter output signal OUT. Offset data are cancelled by each other to obtain only a main digital signal in the subtraction output of the subtractor 2. Thus, the offset voltage is always automatically corrected.

Title: Engine valve lift variable device
Inventor: SAKURAGI SHIGERU
IPC: F01L13/00
Filed: 1989-07-18
Abstract: PURPOSE:To prevent a rocker arm from coming off from the pivot of the rocker arm by mounting a spring which forces the rocker arm to go to the pivot at stopping parts which are formed respectively at the rocker arm and the pivot. CONSTITUTION:Since a rocker arm 21 separates from a pivot 32 at the time of valve opening and the rocker-arm 21 is supported temporarily only at a sliding-contact part with a cam 51 and so forth, there occurs a risk of the rocker arm's coming off to a valve side. To cope with this, the protruding part 61 of the rocker arm 21 and a through hole 62 in the pivot 32 are used as stopping parts respectively for mounting a spring 63 between them. As the rocker arm 21 separates from the pivot 32, the spring 63 is transformed to accumulate elastic force. It is thus possible to use the elastic force of the spring 63 for forcing the rocker arm 21 to go to the pivot 32, which prevents the rocker arm 21 separating from the pivot 32.
