Title: Recording and reproducing device for fm modulation signal
Inventor: OSUE TADASHI
IPC: G11B20/06
Filed: 1981-11-20
Abstract: PURPOSE:To increase the degree of pre-emphasis within a linear range of the input/output characteristics of a tape head system related to the exponent of modulation and to improve the S/N of a high band, by applying the pre-emphasis to the video signal. CONSTITUTION:The composite color video signal is converted into the signal S0 via a pre-emphasis circuit 7 and an FM modulating circuit 8. The circuit 7 has 10-14dB emphasis in terms of the ratio between a level near 10kHz and 3.58MHz for example. The FF10 and FF11 are triggered with the rise and the fall of the signal S0 respectively, and the output signals S1 and S2 are recorded on a tape via the output terminals 14 and 15 respectively. On the other hand, the reproduced FM modulation signal of each channel is synthesized through an exclusive OR gate 20. Then the signal S0 is extracted and then converted into the reproduced color composite signal via a demodulating signal 21, an LPF22 and a deemphasis circuit 23. Thus the reproduced signal S0 is set at 1/2<n> original exponent of modulation which is obtained before division.

Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a joint structure which is excellent in connection reliability and kept free from cracking or delamination caused by thermal stress induced at air bubble interfaces by a method in which the air bubbles are controlled in size and position even if air bubbles are present inside resin at the joint. SOLUTION: The two-dimensional model of a COG chip joint is of three- layered structure composed of chip/resin/glass, and the joint of an anisotropic conductive film is 50μm in thickness. A relation between the diameter and shear stress of an air bubble is obtained through a thermal stress analysis by the use of a nonlinear structure analytical program ADINA, by which it is found that a shear stress induced at an air bubble interface is proportional to the size of the air bubble, and when the diameter of an air bubble is 1/5 as large as the thickness of a resin layer, for instance, 10μm or below, the shear stress of the air bubble penetrating through the resin layer becomes half or below.  When a relation between a distance from a resin/wiring board interface and shear stress is checked, it is found that shear stress is inversely proportional to a distance, so that a resin layer of thickness 3μm or above is provided between an air bubble and an electronic component, and between the air bubble and a wiring board.

Filed: 1994-08-09
Abstract: PURPOSE: To provide a packet protocol for both an interruption request and an interruption reset. CONSTITUTION: An address bus packet is used for reporting interruption and transferring information. When the interruption request is provided, an interruption source requests the use of an address bus. When the use of that bus is permitted, the interruption source sends out an interruption request packet. An interruption controller processes that information and reports the interruption to a processor. At a multiprocessing system, the interruption controller can designate any suitable processor as the route of interruption information. When that interruption is completely processed, the processor issues an alarm to the interruption controller so as to send a reset packet to the interruption source.
