IPC: H01L23/12
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To easily position bumps to the correct positions of electrode pads, by a method wherein the electrode pads, in which the central parts of their surfaces are collapsed into a recess form, are formed from the surface of a wiring board to the interior on the side of a base material and the bumps are fitted in the interiors of these recessed electrode pads. SOLUTION: A surface outer layer conductor 3 on an electronic component mounting surface and a bump connection side surface outer layer conductor 5 are formed on prescribed places on the surface of a glass epoxy base material constituted with a wiring board 1 for electronic component, a phenolic base material or the like by a printing method. Then, recessed electrode pads 6, which are recessed at the central parts of their surfaces, are made to collapse from a bump connection side substrate surface 5A located under the lower part of the board 1 to the interior of the base material to form the pads 6. A conductive paste 8 made by using a creamy solder 28 is filled in the interiors of the pads 6 and in a state that spheric bumps 45 are fitted therein, the bumps 45 are bonded to the pads 6 to temporarily fix the pads 6 on the board 1.

Title: Spiral wedge type optical corrector
Inventor: NISHIDA KAZUHIRO
IPC: G02B5/30
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a spiral wedge type optical corrector having simple constitution and allowed to be easily controlled. SOLUTION: A spiral wedge rink 22 forming a glass wedge like a ring and a circular arc-like wedge 23 are used and the ring 22 is rotated by a motor 24, so that a mechanical end is removed, control can be easily executed and constitution is simplified. Since the reverse rotation of the motor 24 for rotating the ring 22 is unnecessary, it is unnecessary to consider the backlash of a motor or a screw as compared with a conventional device. When the ring 22 and the wedge 23 constitute a light density filter or a phase compensating plate, light density or a phase can be continuously corrected by the simple constitution without using a mechanical limit.

IPC: G11B5/53
Filed: 1989-04-07
Abstract: PURPOSE:To compensate the decrease of the reproduction output signal of a main rotary head which is caused during fast reproduction or reverse fast reproduction and to perform the fast reproduction or reverse fast reproduction without any noise bar by using auxiliary rotary heads and selecting their azimuth angles and rotational planes. CONSTITUTION:The main rotary heads M1 and M2 and auxiliary rotary heads S1 and S2 are fitted to a rotary disk 3 in the same rotational plane at a distance corresponding to the period of two horizontal synchronizing signals of, for example, a video signal. In such a case, the amplitudes of the reproducing signals of the main rotary heads and auxiliary rotary heads are compared and switching to the reproduction outputs of the auxiliary heads is performed in a section wherein the amplitude of the reproduction output signals of the main rotary heads decrease below the amplitudes of the reproduction output signals of the auxiliary rotary heads, so even if the heads differ in reproduction output characteristics or even if the reproduction characteristics vary with time, the rotary head output having a larger reproduction output amplitude can be extracted at all times.
