Title: Grinding device for magnetic head
Inventor: NAKAGAWA TERUO
IPC: G11B5/187
Filed: 1986-03-04
Abstract: PURPOSE:To improve workability and productivity, by a method wherein an upper and a lower fixed cylinders, guiding a grinding table on a peripheral surface, a guide means, preventing a grinding tape from making vertical movement, are provided, and during grinding, a magnetic head is rotated between the upper and the lower fixed cylinders togetherwith a disc. CONSTITUTION:Since a magnetic head 27 is of a type in which it is attached to a rotary disc 26 and rotated togetherwith the disc 26, the plural magnetic heads 27 are attached to the disc and can be simultaneously ground to improve working efficiency. A grinding tape 15, running in a state to be wound around the peripheral surfaces of upper and lower fixed cylinders 11 and 12, from which the magnetic heads 27 are protruded, is apt to move vertically. When the magnetic head 27 is applied as a load (brought into contact with the tape), the magnitude of the vertical movement is sharply increased, and the desired shape of a guide is difficult to form. In which case, a guide means 13 placed on the peripheral surface of a fixed cylinder 10 prevents vertical movement of the grinding tape 15 to stabilize running of the grinding tape 15.

Title: Semiconductor integrated circuit device
Inventor: YAMAGUCHI YOICHI
IPC: H01L21/8238
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To satisfy a wiring lifetime by a single layer and to suppress an increase in a chip area to a minimum limit by altering current densities of wiring widths of power supply wirings and output signal wirings in shapes so as to become constant, corresponding one narrow part of the widths to the other wide part, approaching the parts and forming the parts. SOLUTION: In order to contract a wiring area, power supply wirings 22 and an output signal wirings 23 are changed stepwise in wiring widths. Since a current flowing to the wirings 32 is large in a portion D and a current flowing to the wirings 22 is the smallest in a portion A, the portions where the currents are least correspond to one another. Thus, the wirings 22 and the wirings 32 are disposed so that the widest part B of the wirings 22 and the narrowest part C of the wirings 32 are disposed to be the same position and the narrowest part A of the wirings and the widest part D of the wirings 32 are disposed at the same position. Further, the wirings 22 and the wirings 32 are approached to satisfy wiring lifetime and its wiring area can be contracted.

Filed: 1994-03-17
Abstract: PURPOSE:To eliminate noise components from a displacement signal by adjusting a gain adjusting means in such a way that noise components superposed on the displacement signal, and a noise signal from an amplifying means become equal. CONSTITUTION:The gain of a gain adjustable amplifier 16b is changed by changing the resistance value of a variable resistance. Noise components in the output signal of an amplifier 16a containing noise components, and the output signal of the gain adjustable amplifier 16b formed only of noise components can be thereby adjusted to be approximately on the same level, so that there is no need to accurately set the position relationship between a flow detecting pickup and a noise detecting pickup, thereby facilitating adjustment for noise elimination. This is the action of an inflow side noise eliminating circuit 16, but an outflow side noise eliminating circuit 17 is of the same constitution as the circuit 16.

IPC: H02G15/18
Filed: 1993-03-09
Abstract: PURPOSE:To enhance the insulating characteristic of an insulator layer by filling voids existing in the insulating layer, formed by winding a self-welding tape with an electrically negative gas. CONSTITUTION:Voids (gaps between the abutting parts or lapping parts of a self-welding tape 1) existing in an insulator layer formed by winding the self-welding tape 1) are filled with an electrically negative gas 2 such as SF6, N2, etc., for example, Since the electrically negative gas 2 has excellent insulation resistance and is hard to produce sparks, discharge inside the voids is suppressed by filling the voids existing in the insulator layer with the electrically negative gas, and partial discharge starting voltage and AC breakdown voltage become high. Consequently, it becomes possible to enhance the insulating characteristics at connections of CV (crosslinked-polyethylene-insulated power) cables.
