Patent JP-H09102544-A (JP)
Title: Semiconductor device and its manufacture
Inventor: SEKIGUCHI MITSURU
IPC: H01L21/768
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of a wiring resistance or contact resistance or the occurrence of a junction leak caused by mutual diffusion which occurs between a refractory metal, such as tungsten, etc., and metallic wiring of aluminum, etc., at the time of heat treatment. SOLUTION: A tungsten nitride layer 3e having such a structure that nitrogen atoms and tungsten atoms are bonded to each other in an area near the surface of a tungsten film 3b is formed by exposing the surface of the film 3b to the plasma of a gas containing nitrogen at <=550 deg.C. Then metallic wiring 3 is formed by depositing an aluminum alloy film 3c on the film 3b. The tungsten nitride layer 3e formed by plasma nitrization has such a large barrier function that can prevent the diffusion of other metallic atoms and can be formed in a thin film, because nitrogen atoms and tungsten atoms are bonded to each other in the layer 3e. Therefore, the formation of a high-resistance alloy layer and the occurrence of a junction leak caused by heat treatment can be prevented.

Title: Blowing controlling method
Inventor: MASUDA SEIICHI
IPC: C21C5/30
Filed: 1979-10-08
Abstract: PURPOSE:To improve production efficiency and perform controlling of dynamic type blowing which reduces in-furnace residence time in converter blowing, by using the contents of P and S as control targets together with molten steel temperature and C content, and enhancing the accuracy in the control of the end point. CONSTITUTION:Prior to blowing point of a pure oxygen top blowing converter, the C, P and S contents of molten steel are measured simultaneously with the measurement of molten steel temperature by means of a converter sublance. Based on the thus measured values and the dephosphorization and desulfurization behaviors from the record of precedent charge, the C content CEP at the time when the target P content is attained and the C content CES at the time when the target S content is attained under the target molten steel temperature TA of the blowing end point are estimated and calculated. The oxygen supply amount O2C necessary for lowering these down to the minimum value CE out of these CEP, CES and the target C content CA of the blowing end point is calculated. On the other hand, the oxygen amount OL required for making the C content to the blowdown threshold value and the oxygen amount O2T necessary for making molten steel temperature to a target value are calculated, thence O2C, O2L, O2T are compared and cooling material is charged or slag making agent is added.

IPC: B29C53/06
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To form a sharply bent part by stably shaping without deformation due to damage or spring back by separating reinforcing fiber along a ridge of a mold shape of a fiber-reinforced sheet before the molding step of a profile section. SOLUTION: An end of a rod-like member 3 having the end including a radius of curvature of, for example, 3 mm or less is brought into contact with a site to be a ridge of a profile section of a fiber-reinforced sheet 1 on a table 2, and the sheet 1 is moved in a lengthwise direction. The fiber 3 and table 2 become a means for forming a flute for forming the ridge of the profile section composite material at the sheet 1. When the end of the material 3 is pressed to the sheet 1, a surface of the table 2 having elasticity is recessed, and the sheet 1 is drawn, and hence a flute 4 is formed along the moving direction at a position to become the ridge of the section of the sheet 1. Thereafter, it enters the molding step.

Title: Path controller for data communication network
Inventor: OYAMA TETSUO
Filed: 1986-06-05
Abstract: PURPOSE:To relieve the load of a central processing unit by sending a redundancy bit discriminating the high-order direction and the low-order direction to a communication line between controllers in a data communication network. CONSTITUTION:Controllers 2-6 take either one of channels 7-12 connected to itself as a high-order direction and other channels 7-12 are taken as a low-order direction. The controllers 2-6 send the data from the high-order direction in a direction receiving a redundant bit '1' from the opposite controller in the low-order directions. In case of the data from the low-order direction, the controllers 2-6 fetch the data only from the channels 8-12 receiving the redundant bit '1' and send the result in the high-order direction. Through the operation above, a communication path decided definitely is set between a central processing unit 1 and the controllers 2-6. Thus, the load of the unit 1 is relieved.

Abstract: PURPOSE:To enable cleansing of a flux by a method wherein a metallized part of the bottom surface of a ceramic carrier is projected and thereby an aperture is made between the bottom surface with no metallized layer and a substrate. CONSTITUTION:The outer edge of the bottom surface of the carrier continuing to an outside lead 14 is formed into a projection 22. The metallized part 18 is formed in extension on the lower surface of the projection. Moreover, in the projection 22 are provided passing grooves 23 for cleansing liquid at the time of cleansing of the flux. When the metallized part 18 is soldered to the wiring 20 of the substrate 19 in this constitution, a large aperture l2 is produced between a nonmetallized part 11a and the surface of the substrate 19, while the outside and inside are communicated with each other through the grooves 23. Accordingly, the cleansing liquid is made to pass inside the aperture l2 through the grooves 23 after soldering, whereby the flux can be cleansed effectively. By this the erosion of the lead is prevented and the reliability and durability of the device is improved.
