Inventor: ISHIDA TOMIO
IPC: H01F17/04
Filed: 1981-09-16
Abstract: PURPOSE:To obtain high inductance by a method wherein the ratio of the grain size of a magnetic core section to that of the magnetic substance of an outside edge magnetic substance section is formed in the range of twice to five times. CONSTITUTION:A magnetic substance green sheet 2 printed with a conductive paint 3 is wound on a magnetic substance winding core 1 to obtain a columnar substance by burning. The magnetic substance winding core 1 is made by applying roll kneading to ferrite powder and a binder and pushing out the ferrite powder and the binder. After applying ball mill mixing to the ferrite powder and the binder, the green sheet 2 is formed by coating. Therefore, the magnetic substance winding core has higher density than that of the green sheet and the magnetic core section 1 has bigger magnetic substance in gain size after burning and higher inguctance can be obtained in the above range. The green sheet 2 has higher coefficient of contraction at baking and suitable clamping pressure is generated to obtain a burned substance having no delamination.

Filed: 1993-05-25
Abstract: PURPOSE:To provide an uneveness patterning method onto the surface of ceramic-based architectural material, with which enough deep and sharp uneveness patterning can be embodied even when the uneveness pattern is clearcut one. CONSTITUTION:In the case of uneveness patterning by applying linear pressure from the top surface of a patterning mold 3 with a press roll 4 under the condition that the patterning mold 3 is held on green product 1, which is ceramic- based product 1 extruded in a specific crosssectional form on a carrier retainer plate 2, uneveness pattern is so constituted as to be produced by being pressed with the press roll 4 having a non-linear contour producing line so as to make the outer diameter RA at the portion corresponding to the projected mold part of the matterning mold for producing recessed pattern on the product with press roll 4 smaller and the outer diameter RB at the portion corresponding to the recessed molded part for producing projected pattern. Thus, by making the linear pressure applied with the roll different from each other, material is flown laterally, resulting in forming sharp base part in clearcut uneven pattern.

Title: Tracking system of magnetic recording and reproducing device
Inventor: YAMADA KOUICHI
IPC: G11B15/467
Filed: 1982-08-24
Abstract: PURPOSE:To ensure stable control, by sampling and holding a tracking error signal obtained from a pilot signal recorded with superposition on an information signal synchronously with a head switching signal and having the relative control between a track and a head locus. CONSTITUTION:A head switching signal (a) is supplied from a terminal 15 to a monostable multivibrator MM16 which is triggered with the rise or fall of the signal (a). A pulse output signal (c) which is synchronous with the signal (a) and has a proper time width is obtained from the output of the MM16. The signal (c) is supplied to an MM17 to obtain a pulse output signal (d) having a comparatively short time width. A tracking error signal (b) having a large variation of level is supplied to a terminal 18 and then supplied to a sampling/ holding circuit 19. The signal (d) is supplied to the circuit 19 to obtain a held output signal (e). The signal (e) has virtually no variation of level and therefore supplied to a capstan motor as a phase error signal. Thus the wow is greatly reduced for a control system.

Title: Optical fiber array component
Inventor: SUDA HIROYUKI
IPC: G02B6/44
Filed: 1992-06-08
Abstract: PURPOSE:To enable the use of optical fibers whose cover has a large outside diameter by stacking the optical fibers into more than two layers, and horizontally arraying the optical fibers from the glass part array position of the output end face of each of the optical fibers to an initial cover portion. CONSTITUTION:Loose optical fiber cores from which an end plastic cover is partially removed are stacked into two layers each having e.g. four cores and are sandwiched between two flat panels and are arrayed and temporarily fixed by a plastic tape. The stepped level of a substrate component 6 is set such that the optical fiber core positions of an array groove component 5 are adjusted to the vertical and cross center portions of the stacked optical fiber cores and then the substrate component 6 is fixed by an adhesive which keeps an elastic state. Thereafter the end face of an array portion is polished to provide an optical fiber array component. The optical fiber cores are thus stacked and arranged into multilayers so that they can be employed even with differences in the structure and the use of optical fibers 4.
