Title: Reinforced structure of protective film for semiconductor device
Inventor: AMANO AKIRA
IPC: H01L21/321
Filed: 1989-02-21
Abstract: PURPOSE:To back up a strength of a protective film and to prevent a crack from being produced by forming a reinforcement film on a protective film, with which a peripheral edge of a metal film arranged and formed on a chip of a semiconductor device is covered, in such a way that a range near the peripheral edge of the metal film is covered and that the metal film is surrounded from the outside. CONSTITUTION:A protective film 4 is used to cut a semiconductor device off from an influence by the open air and is produced by a dense organization such as silicon nitride or the like; however, this organization is hard, causes a crack easily and is damaged easily. Therefore, a reinforcement film 10 is formed on the protective film 4 in such a way that range near a peripheral edge of a comparatively large-sized metal film 3 used for a connection pad or the like is covered and that the metal film 3 is surrounded from the outside. Accordingly, even when a thermal strain is caused in the protective film 4, a strength of the protective film 4 is backed up while a thermal stress is being alleriated by the reinforcement film 10. A metal whose adhesion property to the protective film 4 is good, e.g. titanium, chromium, or a resin, e.g. a polyimide resin, is used as the reinforcement film 10. Thereby, it is possible to prevent a crack and damage of the protective film 4.

Abstract: PURPOSE:To reduce the influence of internally reflected beams due to optical parts by arranging optical parts in a beam waist forming area so as to have their end faces inclined at an angle to a plane orthogonal to the optical path of optical system of coupled lenses. CONSTITUTION:The optical signal incident from the first optical fiber 11 is sent to the second fiber 12, and the optical signal incident from the fiber 12 is sent to the third fiber 13. A Farady rotator 22 in the beam waist forming area is provided at an angle alpha to the optical path, and thereby, end faces 24 and 25 of the rotator 22 are inclined in the horizontal direction at the angle alphato the plane orthogonal to the optical path of a lens coupled optical system 14. Consequently, the beams reflected on end faces 24 and 25 of the rotator 22 are deviated form the optical path of the optical system 14 and cannot be coupled optically on end faces of fibers 11 and 12. Thus, the influence of internal reflected beams due to optical parts in the beam waist area is reduced considerably.

Abstract: PURPOSE:To reduce the amount of NOx and expand the variable range of turn down ratio (TDR), by a method wherein a combustion chamber is formed so that combustion chamber walls, provided with a plurality of flame ports, are opposed to form opposed flames between the combustion chamber walls mutually while the flame ports are arranged locally and crowdedly so as to form a plurality of groups. CONSTITUTION:When liquid fuel is used, a sheath heater 11 is energized and the fuel is injected through a nozzle 13. The liquid fuel 16 collides against an evaporating tube 10 to evaporate, mixes with air sent simultaneously together with the fuel, and thereafter passes a throat to become a uniform mixture 18. Then, the mixture 18 is supplied through a mixing chamber 7 into a combustion chamber 5 through flame ports 6 and ignited by an ignitor 14, whereby opposing flames 19 are formed. After effecting premixed combustion, exhaust gas 20 is discharged. The opposing flames 19, formed in such a manner, form points of stagnation at the parts whereat the flames are collided and the flow speed of the exhaust gas is reduced, whereby the flames are stabilized. The flame ports 6 are arranged so as to form a plurality of groups 6A on the combustion chamber walls 2' therefore, the flames are dispersed remarkably and the temperature of the flames is reduced, whereby low NOx combustion may be promoted and the variable range of turn down ratio (TDR) may be expanded.

Abstract: PURPOSE:To detect the number of turns exactly at all times by forming a concave on the outer circumferential surface of the rotary shaft and by providing a detecting part of an electromagnetic detector for detecting the rotation speed so that it can be faced to the concave. CONSTITUTION:The electromagnetic detector 27 contains a detecting head that consists of the core 30 and the coil 31, both ends of the coil 31 are connected to the external terminals 32, 33 respectively. The terminal 32 is grounded through the resistance 34, and is also connected to the wave form shaping circuit 36 through the capacitor 35. The output side of the shaping circuit 36 is connected to the input side of the frequency converter 39 through the capacitor 38, and is connected to the tachometer 41 through the resistance 40. When the rotary shaft 8a turns, magnetic resistance is changed by the core 30 and the rotary shaft 8a every time the air vent 25 formed in the shaft 8a faces to the detecting part 28, resulting in the development of voltage at the external terminal 32. Also the transformer 39 provides a voltage output proportional to the frequency of a pulse emitted by the shaping circuit 36. In this way, the number of turns of the rotary shaft can be detected by the tachometer 41.
