Title: Spacer made of silicon foam
Inventor: OKUDERA TAKASHI
IPC: A61L27/00
Filed: 1989-09-26
Abstract: PURPOSE:To obtain the spacer which withstands long-term implantation, allows permanent detention and allows the easy checking of the insertion position and shape even after operation by using silicon as a base and forming the spacer to the average cell size and average film thickness of specific sizes. CONSTITUTION:The spacer made of the silicon foam is the silicon foam to be detained between the cerebral nerves and blood vessels and has 0.6 to 3mm average cell size and 0.2 to 1.5mm average film thickness. This spacer is constituted by mixing the fine powder of alumina, yttrium oxide, the compd. of the alumina and the yttrium oxide, stabilized zirconia, partially stabilized zirconia, barium carbonate, and pure titanium with the silicon foam. The spacer is constituted of such silicon foam and has the small probability that an excessive reaction is induced in a living body even if the spacer is implanted into the living body over a long period of time. In addition, the pressure reduction between the nerves and the cerebral blood vessels can be adequately executed. Further, the position where the spacer is inserted in the living body is easily and exactly checked by radiophotography if the particles of pure titanium are dispersed into the silicon foam.

Title: Semiconductor stress sensor
Inventor: SAITO KICHIZO
IPC: G01L1/00
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor stress sensor taking advantage of a field effect transistor of the structure suitable for detection of generated stress at high sensitivity. SOLUTION: A surface layer SL, whose resistance is higher than the internal part BL, is formed on the surface of the semiconductor substrate located directly under the gate electrode G of a field effect transistor. Suitably, the high resistance surface layer SL is formed by the doped donor and the acceptor, which is generated by the compressive stress when the gate electrode is formed, are almost cancelled with each other. This field effect transistor functions as a JFET by the change of the surface layer SL into a p-type when compressive stress is generated, and the field effect transistor functions as an MESFET by the change of the surface layer into n-type when tensile stress is generated.

Abstract: PURPOSE:To improve catalytic performance by allowing an oxide as a preliminary processing material to be borne on a thin wall support with a low coefficient of water absorption of a monolithic structure and then further allowing a specified catalytic component to be borne. CONSTITUTION:A specified catalytic component is allowed to be borne after an oxide as a preliminary processing material is allowed to be borne on a thin wall support with a low coefficient of water absorption of a monolithic structure. The oxide with a low coefficient of water absorption of a monolithic structure consists of a fireproof metal oxide with a coefficient of water absorption of 12wt.% or lower. The most favorably used support is a honeycomb support of cordierite. The thin wall design is for reducing a pressure loss when the catalyst is mounted on a vehicle and the actual wall thickness is 90% or lower than that of the conventional catalyst. The preliminary processing material is selected from among activated alumina, activated silica, cerium oxide, ziconium oxide and titanium oxide. The catalytic component is platinum element, activated aluminum or cerium oxide. Thus catalytic performance is enhanced.

Title: Electronic camera and recording medium recording image processing program
Inventor: KUNIBA HIDEYASU
IPC: H04N19/186
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To correctly decide a compression parameter by which a target compression rate is attained by only a few test compression times by calculating the proper compression parameter to obtain the target compression rate and compressing image data through the use of the calculated compression parameter. SOLUTION: A compression processing part 18 executes communication with a control part 21 and obtains compression image quality setting by an operation button group 24. The part 18 decides the target compression rate in accordance with the image quality setting. Then approximation is obtained by a relational expression: Y=g/(X+c)+h (g, c and h are an unfixed parameter) so that 'relation between the compression parameter X and a compression code amount Y' which indicates an inverted S shape curve is excellently approximated within a wide range. The compression parameter X which seems to be proper in attaining the target compression rate is correctly obtained by the inverse calculation of the relational expression. Then the test compression times are efficiently reduced.

Title: Thermal transfer type color recorder
Inventor: OBARA KAZUKI
IPC: B41J17/36
Filed: 1987-10-06
Abstract: PURPOSE:To prevent wasteful printing by a trailing end part of an ink ribbon from being carried out, by indicating a near-end condition when a threshold value for a near-end velocity is exceeded by the feeding velocity of recording- starting marks on the ink ribbon. CONSTITUTION:Marks 31 indicates positions for starting a printing sequence. An ink ribbon 29 is taken up on a take-up roll 9. The number of basic clock signals generated from an oscillating circuit 34 in the period from the moment the mark 31 reaches a sensor 30a to the moment the mark 31 is fed past the sensor 30a is counted by a velocity detecting circuit 35, thereby measuring the passing velocity. With the number of the clock signals thus detected, a threshold value for the number of clock signals at which to issue a near-end indication is fetched from a controlling part 37, and the detected number is compared with the threshold value by a comparing circuit 38. When the threshold value is exceeded by the detected number, the near-end indication is given by an indication lamp. By this, it is possible to prevent printing by a trailing end part of the ribbon from being carried out.

Title: Manufacture of crosslinked polyolefin resin foam
Inventor: KENMOTSU TAKAAKI
IPC: B32B27/32
Filed: 1988-10-07
Abstract: PURPOSE:To make the surface smooth and improve cushioning properties, by a method wherein only a surface layer of a laminated body is crosslinked by applying ionizing radial rays to the surface layer and then a sheet core body and the surface layer are foamed by heat-treating the whole of the laminated body. CONSTITUTION:A sheet core body is comprised of a composition obtained by adding a foaming agent and chemical crosslinking agent to polyolefin resin.A surface layer of a sheet becomes an appropriate crosslinked state when ionizing radial rays are applied to the surface layer of a laminated body comprised of a composition obtained by adding only a foaming agent to the polyolefin resin.Then, when the whole is foamed through heating, a radical generated within the sheet core body advances crosslinking of the polyolefin resin of the sheet core body without being caught by oxygen in air through a barrier effect of its surface layer and cracked gas also from a foaming agent is not dispersed. Therefore, the title method can be used effectively for raising foaming magnification of the core body, the surface is free from also skin irritations due to dispersion of the cracked gas and since the surface layer itself also becomes a foam, flexibility becomes favorable.
