IPC: H01L21/66
Filed: 1986-06-17
Abstract: PURPOSE:To observe an original sectional structure even if a semiconductor element has any surface film by O2-plasma processing the surface of the element to form an oxide film on the surface, then cutting the element, processing the section with medicine having breakdown strength, and then observing the sectional structure. CONSTITUTION:A semiconductor element having a laminated structure of a thermal oxide film 2, a polysilicon 3, an interlayer insulating film 4, aluminum wirings 5 and an insulating film (PSG) 6 on an Si substrate 1 is O2-plasma processed to oxidize the film 6 of the uppermost surface, thereby forming a thin oxide film 7. Then, the processed element is cut, dipped in a mixture solution of nitric acid and fluoric acid to slightly etch the section. At this time, the surface of the element is formed with the film 7. Thus, it is scarcely etched. In this manner, the element having any surface film can be reproduced with a sectional structure in which a boundary of the layers is clarified without loss of the original structure to be effectively used for evaluating a step coverage and analyzing an abnormal part.

Title: Surface treated steel plate for fuel vessel
Inventor: HIGUCHI YUKINOBU
IPC: C25D7/00
Filed: 1981-09-09
Abstract: PURPOSE:To obtain a surface treated steel plate for fuel vessels having corrosion resistance to gasoline contg. alcohol by applying an Sn plating layer on the upper surface of an Ni or Ni-Co alloy layer which is an underlying layer on the surface of the steel plate. CONSTITUTION:Ni or an Ni-Co alloy is plated by electroplating, etc. on the surface of a steel plate which has passed through a surface cleaning stage. An Sn plating layer is applied by a method such as electroplating on the upper layer of the underlying plating. The Sn plating layer decreases the pinholes generated in the stage of applying the underlying plating and improves corrosion resistance accompanied with the corrosion preventing effect of the sacrificing anode in the pinhole parts. If the thikness of the total plating layers of the Ni or Ni-Co alloy plating layer and the Sn plating layer are <0.25mu, many pinholes remain and if >=15mu, workability degrades; therefore said thickness are kept at 0.25- 15mu. The corrosion resistance is improved further by applying a chromate film or phosphate film thereon.

IPC: F02B77/08
Filed: 1987-06-08
Abstract: PURPOSE:To perform adjustment for a load detector being high in accuracy as well as to improve its load detecting accuracy by performing the adjustment of the load detector of a Diesel engine at an area where a torque variation is small to an engine speed variation. CONSTITUTION:Adjustment of a load detector of a Diesel engine is performed at an F point which is in and around a boundary between an area C and another area D and simultaneously it is equivalent to an area B. Output control is in this area B where a torque (injection quantity) variation is relatively small to an engine speed variation. At time of the output control, it is made so hard to be influenced by the speed variation as the adjusting conditions, and since torque sensitivity is good enough against the opening, highly accurate adjustment is made attainable.

Title: Semiconductor laser
Inventor: NISHI KENICHI
IPC: H01S5/00
Filed: 1985-06-28
Abstract: PURPOSE:To control oscillating wavelengths by applied voltages, by monotonously changing the width of the forbidden band of a semiconductor layer, which has the narrow width of the forbidden band, among semiconductor layers constituting a semiconductor thin film, with respect to the laminating direction. CONSTITUTION:A semiconductor laser has a multilayer heterostructure. An active layer has a thin film structure, in which one or more semiconductor layers wherein the thickness is less than about the mean free path of electrons, are laminated in many layers. A means for injecting a current into the active layer is provided. A means for applying an electric field in the laminating direction is also provided. Of the semiconductor layers constituting the thin film structure, the width of the forbidden band of the semiconductor layer having the narrow forbidden band width is monotonously changed in the laminating direction. Namely, since the amount of inclusion of Al is gradually increased and the quantum well layers 34 are grown, the forbidden band width is expanded in the direction toward the upper surface of a substrate. Even if the oscillating wavelength is changed by changing an absorbing end, the phenomenon such as difficult oscillation due to rapid increase in oscillating threshold current value is hard to occur.
