Title: Magnetic head device
Inventor: SUGAWARA NOBUHIRO
IPC: G11B5/60
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To improve an internal transfer speed of a hard disk by arranging mutual positional intervals among high frequency current transmission wirings to be connected with a recording head and a recording preamplifier so as to be within a specific range. SOLUTION: When a recording head of a hard disk is driven with a high frequency, a high frequency current is, normally, transmitted from a recording preamplifier 3 to an arm 9 and to a recording head chip 13 through a suspension 10 via high frequency current transmission wirings 12. It is preferable that the high frequency current transmission wirings 12 are installed so that positional intervals among the high frequency current transmission wirings 12 are each 0.1 μm to 15 μm. Thus, it is possible to reduce cross magnetic fluxes passing the gap between the high frequency current transmission wirings 12, and reduce the inductance of the high frequency current transmission wirings 12.  Namely, the inductance of the high frequency current transmission wirings 12 occupies about 60% of a total inductance of the recording head, therefore, the whole inductance of the recording head can be reduced substantially.

Abstract: PURPOSE:To obtain a proper reproduced image without reference to the mount state of the document by measuring the light of formation, and selecting a low-level and a high-level light measured value range according to light measured values in a light measurement area and determining an image area or background area. CONSTITUTION:The minimum density value Dmin and maximum density value Dmax in the light measurement area (e.g. area matching with the largest area in a document to be copied) of the color document are determined. Then light measured density limit values (Dmin+alpha) and (Dmax-beta) which can be regarded as extremely low and high levels are stored in a light measuring means. Here, alpha is a density value and about 0.01-0.20 and beta is about 0.05-0.50. Then an area having picture elements where the light measured density value di of each small part (picture element) of the document which is read by utilizing a light measuring means is Dmin+alpha<=Di<=Dmax-beta is determined as an image area and other areas are determined as a background area prior to a copying process. An area density value regarding one of both areas is found and used as one arithmetic element to determine the best copy exposure quality, thereby performing control.

IPC: G05F1/10
Filed: 1982-07-15
Abstract: PURPOSE:To simplify the structure of a noninterference device, by feeding back a current measurement value in a voltage operation-enabled coil and current differential value generated by a digital differential filter in a short-circuiting coil. CONSTITUTION:An output (y) generated when short-circuiting coil current ip is selected is used as an input of a digital type differential filter 50 in stead of the differential value of the short-circuiting coil current ip. In controlling intermediate values u1, u2, u3, voltages to be applied to respective coils is found by an equation (Akm: deltakm+Mkm/Lm, Bkm: -MkmRm/Lm, deltakm: Kronecker's delta, Mkm: mutual inductance of coil, Rm: resistance, Lm: self-inductance of coil). The application of these voltages forms the relation of uk=(Rk+SLk)ik between the control intermediated values u1, u2, u3 and current i1, i2, i3 and the coil looks independent apparently. If the outputs of the control system are u1-u3, three methods may be considered for the current control of the independent coil.
