Abstract: PROBLEM TO BE SOLVED: To form a stent to a flat form by constituting the stent of transverse branches including waveform projections of a width and thickness in a range of specific values and longitudinal branches of a width and thickness in a range of specific values. SOLUTION: This stent for blood vessels comprises the transverse branches 1 and longitudinal branches 2 consisting of stainless steel materials. The transverse branches 1 among these branches contain the projections of the waveform of about 0.3 to 0.8 mm in height.

Title: Multilayer interconnection structure body and its manufacture
Inventor: YAMAMOTO EIICHI
IPC: H01L23/52
Filed: 1989-08-04
Abstract: PURPOSE:To realize an interlayer connecting pillar which is fine and whose aspect ratio is large without increasing an interconnection pitch and to obtain a multilayer interconnection structure body which can realize an interlayer interconnection which is fine and whose density is high by a method wherein the surface of a lowerpart interconnection layer coming into contact with the interlayer connecting piller is constituted of a metal nitride layer or a metal layer/a metal nitride layer which is different from the interlayer connecting pillar. CONSTITUTION:For example, an Al alloy layer is deposited as a metal for pillar use; after that, an Al alloy pillar 17 for interlayer connecting conductor pillar use is formed by a well-known lithographic technique and a dry etching technique. When, at this process, a reactive ion etching method by silicon tetrachloride gas is used for the dry etching technique and a processing operation is executed under conditions of 1 to 2 Pa and a power density of 0.2W/cm<2>, a selective ratio of an Al alloy to a Ti nitride can be set to be large at 7 to 9. Consequently, an extremely thin Ti nitride layer 14 can act as an etching stopper layer when the Al alloy pillar 17 is processed; a good processing operation without an etching residue can be executed by a sufficient overetching operation in consideration of an etching nonuniformity.

Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To suppress increasing of a pressure loss so as to eliminate necessity for increasing of a capacity of a drive motor, by forming a sectional area inside a hydraulic pipe in the vicinity connected to an oil muffler smaller than a sectional area inside the other hydraulic pipe. SOLUTION: A sectional area inside a hydraulic pipe 10 in a part of length Lo in the vicinity connected to an oil muffler 5, of hydraulic pipes 9, is set to S3. This sectional area S3 of the hydraulic pipe 10, sectional area S1 inside the oil muffler 5, and a sectional area S2 inside the hydraulic pipe 9, are set so as to obtain a relation S1>S2>S3. Further, the length Lo of the hydraulic pipe 10 and the sectional area S3 are set in a range without increasing a capacity of a drive motor. By this constitution, since the sectional area S3 of the hydraulic pipe 10 in a part of the length Lo connected to the oil muffler 5 is decreased in a range without causing a capacity increase of the drive motor, a damping effect can be improved without causing the enlargement of the oil muffler 5, the deterioration of installation workability, increasing of a cost, etc.

Title: Chip resistor
Inventor: CHIBA TOMIYASU
IPC: H01C13/02
Filed: 1988-08-16
Abstract: PURPOSE:To enable high precision functional trimming even if cutting distance is lengthened by arranging two or more resistors, having different sheet resistance, connected in series on the same substrate to form a chip resistor. CONSTITUTION:A high resistance side resistor 3a formed on a substrate 1 of a chip resistor 5 is trimmed in the X1 direction, and the trimming of the high resistance side resistor 3a is stopped at a point where the cutting distance A is just before reaching a value to change the resistance value largely. Then, to achieve high precision trimming, a low resistance side resistor 3b for fine adjustment is trimmed in the X2 direction until a resistance value R1, to realize a desired functional characteristic value, is obtained. In this chip resistor, because the resistor with a low sheet resistance value is introduced, the changing rate of the cutting distance versus resistance function after the definite cutting distance A is reached becomes smaller than that before A is reached as shown by a solid line b, so that high precision trimming can be effected though there is a time lag from the production of the trimming stop signal at the functional trimming device to the trimming stop.

Abstract: PROBLEM TO BE SOLVED: To enable high speed rendering even when there is eccentricity in object arrangement in a three-dimensional(3D) space by dividing a boxel when the number of polygons in each boxel is higher than an allowable value and coupling the boxel with the adjacent boxel when that number is lower. SOLUTION: A dividing control means 14 prepares a cube including an object from 3D data, afterwards, divides that cube into boxels in a previously designated size and sets polygon information in each boxel to a boxel table 24. A storage means 12 stores an allowable value for the number of polygons and investigates the number of polygons in each boxel from the table 24. Then, the boxel having the number of polygons greater than the allowable value is further divided and concerning the boxel having that number smaller than the allowable value, when the number of total polygons in the adjacent boxel is settled within a allowable value range, these boxels are coupled into one.  Besides, the boxel in which no polygon exists, is deleted from the table 24 and when the number of polygons in each boxel is equal to or less than the allowable value, a processor 10 performs rendering while discriminating the looseness of rays and boxels.
