Abstract: PURPOSE:To obtain high corrosion resistance by the outermost layer and high sacrificial corrosion preventive effect by the layer on the inner side of the outermost layer by forming an Al rich layer on the outermost layer and lowering the Al content of the layer on the inner side lower than the Al content of the outermost layer. CONSTITUTION:An Al/zinc alloy plating layer 2 is formed on a material 1 to be plated and the layer of the Al content higher than the Al content of the layer 2 is formed on the outermost layer 3 of the layer 2. The material 1 to be plated is, therefore, immersed into a molten zinc bath and after the material 1 is taken out of the bath, the material is immersed into a molten Al/zinc alloy bath. The material is taken out of the bath and is cooled, by which the Al/zinc alloy plating layer is formed. The material is rapidly cooled down to about 450 to 500 deg.C at this time, by which the Al is rapidly solidified and the zinc in the molten state is pushed downward. The Al rich layer is thus formed on the outermost layer 3. The material is thereafter cooled at the rate lower than the above-mentioned cooling rate, by which the Al/zinc alloy plating layer 2 in the part inner than the outermost layer is solidified and formed.

Title: Semiconductor device and its preparation
Inventor: PIITAA ROOSON WAINDO
IPC: H01L29/739
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To form an emitter window without using any highly accurate photolithographic technique by forming an emitter structure having a recessed section which is combined with its overlying metallization. SOLUTION: A silicide layer 8 improves the electric contact between a source diffusion region 6 and a body diffusion region 4 along the bottom and side wall of a recessed section A. A deposited insulating layer 9 is used for covering a gate region on the side wall of the recessed section A. Aluminum metallization 10 is formed on the gate region so that the metallization 10 can come into contact with the bottom section of each emitter cell. Since the silicide layer 8 is used to distribute the electric current below the insulating layer 9 to the source region 6, the metallic layer is only required to come into contact with the center of each cell. The diffusion area of each cell and the strap of the silicide layer 8 are formed in a self-aligned fashion except a contact window B formed in the insulating layer 9.  The advantage of this structure is that a small emitter window can be formed without requiring very accurate alignment for photolithography.

Abstract: PROBLEM TO BE SOLVED: To reduce the amt. of the decomposition residue by injecting a small amt. of water into a thermal decomposition reactor in a process for decomposing plastic wherein plastic is decomposed in the absence of oxygen and the resultant gas is cooled to recover an oil. SOLUTION: Water is injected into a thermal decomposition reactor in a process for decomposing plastic wherein plastic is thermally decomposed in the absence of oxygen and the resultant gas is cooled to recover an oil.

(pref. 0.01-0.5pt.wt.) based on 1.0pt.wt. plastic present in the reactor. Thus, the decomposition is performed quickly at a high temp. while reducing the generation and deposition of the decomposition residue and improving the oil recovery ratio.

Title: Multi-contact connector
Inventor: TAKAHASHI TAKUMI
IPC: H01R9/16
Filed: 1994-07-13
Abstract: PURPOSE:To avoid the generation of the insulating material of a connector contact due to fine slide in a multi-contact connector used for connecting a number of signal lines in parallel. CONSTITUTION:A spring contact 3 is formed in the structure of being elastically deformed in the inserting and extracting direction of a connector to make the spring contact 3 abut on a pin contact 16 or the spring contacts abut on each other for making contact. A contact part is formed at the top part 7a of an inwardly bending side 7 by bending the spring contact 3 inwardly after once bending it outwardly so as to produce flexibility only in the inserting and extracting direction of the connector, The head part 15 of the pin contact is formed in a flat form which has a large width in the extending direction of the spring contact. The spring contact can be formed in the structure in which the spring contacts of an identical form are opposed in symmetry to a line for making contact. The extending direction of the contacts 3, 16 is slightly tilted to make crossing contact in plane view, thereby being able to assure sure contact even when the fitting of the connector gets out of position. In the structure according to this invention, a very fine slide between the contacts due to vibration is not brought about, so that the generation the insulating material of a contact due to fine slide can be prevented.
