Patent JP-H098348-A (JP)
Title: Light emitting diode and fabrication thereof
Inventor: HIRAMOTO HIROYUKI
IPC: H01L33/30
Filed: 1995-06-16
Abstract: PURPOSE: To prevent the diffusion in different pattern by depositing an anti- diffusion film, i.e., SiO, as a first layer touching a GaAsP layer tightly, and then depositing SiN as a second layer on the SiO before forming a diffusion pattern on the anti-diffusion film. CONSTITUTION: SiO2 3a is-deposited as a first layer touching a GaAsP layer 2b tightly thus enhancing adhesion thereto and preventing the possibility of stripping. SiO2 3a is also excellent in adhesion to SiNx 3b. When Zn is diffused thermally, the SiO2 3a and SiNx 3b function complementally each other to prevent diffusion. When a pinhole is present in the SiO2 3a, for example, the more compact SiNx 3b closes the pinhole thus preventing abnormal diffusion, i.e., diffusion in different pattern.

Title: Production of high-nitrogen cold-rolled steel plate
Inventor: MIKI SHINICHI
IPC: C21D9/52
Filed: 1979-12-26
Abstract: PURPOSE:To improve the workability in high-nitrogen cold-rolled steel-plate production by a method wherein a low-carbon rimmed steel plate finished to a specified thickness is subjected to recrystallization annealing and then is nitrized at a specified temperature. CONSTITUTION:A slab is subjected to normal hot and cold rolling processes to form into a low-carbon rimmed steel plate in 0.5-2.3mm. thickness. In a loose coil condition, the steel plate undergoes recrystallization annealing in an atmospheric gas of hydrogen and nitrogen. A preferably composition of the atmospheric gas is of about 2-20% of hydrogen and about 80-98% nitrogen. Then, at steel temperature exceeding 500 deg.C, a small amount of ammonia gas (less than about 1%) is added to and mixed into the atmospheric gas, the temperature is maintained at a specified period, and then steel plate is gradually cooled. The process improves the workability in casting operation and the surface properties of slab.

Filed: 1988-07-15
Abstract: PURPOSE:To prevent a waving on an abutting surface by executing a fix-holding between a developer regulating member composed of an elastic body and a supporting body to support it by means of adhesion. CONSTITUTION:A elastic blade 5 is bond-fixed through an adhesive layer 13 to a supporting member (holder) 6 fitted to a developing device in the base part of the surface at the same side as the abutting surface with a developing sleeve 7. Since the developer regulating member is fixed to the supporting member evenly in a bus direction by means of the adhesion in such a way, the waving due to the partial strongness and weakness of a fixing force cannot be generated, and even under a particular environment such a low temperature, low humidity and a high temperature high humidity, the developer on a developer carrier can be maintained in an even thick layer.

IPC: B32B18/00
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To enable production of a ceramic green sheet laminate precisely according to the design dimensions and improvement in yield by forming an internal electrode conductor paste film on a surface of a ceramic green sheet after forming a recess on the opposite surface in a specific relationship with the conductor paste film that is printed on another sheet and faces the receded portion when the sheets are laminated. SOLUTION: A recess 43 is formed on a surface 41A of a ceramic green sheet 41 formed by applying ceramic slurry on a surface of a carrier film 40, in a portion where a conductor paste film 45 formed on another ceramic green sheet is positioned when the sheets are laminated. The recess 43 of the ceramic green sheet 41 is shaped to have the same shape as the pattern of the conductive paste film 45 formed on the ceramic green sheet that faces the sheet 41 and have a depth equal to the dry thickness of the paste film 45. Therefore, when a plurality of such ceramic green sheets 41 are laminated, the recesses 43 serve as relieves for the conductor paste films 45, avoiding deformation of the films 45 due to pressurization. Thus, the method is able to produce a ceramic laminate precisely according to the design dimensions and prevent a reduction in yield.
