Title: Exhaust gas emission control device for internal combustion engine
Inventor: KANESAKA HIROYUKI
IPC: F01N3/20
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To perform high-efficient forced desorption treatment of an exhaust gas component by bringing an air-fuel ratio into a rich state at an optimum timing. SOLUTION: An SOx absorbing catalyst 4 is arranged upper stream from an NOx absorbing catalyst 3 in the exhaust passage 2 of an internal combustion engine 1 and inflow of an SOx component to the NOx absorbing catalyst 3 is prevented from occurring. Absorbed NOx is needed to effect desorption by bringing an air-fuel ratio into a rich state before saturation and based on a running route decided by a navigation system 11 for a vehicle, a running condition under running is estimated and an optimum desorption treatment timing is predicted. Thus, high-efficient desoprtion treatment is executed at a timing at which a condition, such as an exhaust gas temperature, is suitable for desorption.  When it is predicted that a discharge SOx amount under running exceeds an absorbable amount, desorption treatment is immediately executed without waiting for a timing, and an outflow of SOx is surely avoided.

IPC: B65D81/26
Filed: 1989-02-21
Abstract: PURPOSE:To impart a shelf life equivalent to metal can at low costs and a freedom of improving the design and print of a container by placing a plastic container filled with sterilized contents into a bag consisting of metal, providing an oxygen absorbent between the bag and the container and packing the container under vacuum or displacement with an inert gas. CONSTITUTION:A plastic container 1 filled with contents A and sealed with a lid 2 is subjected to retort or boil sterilization. The container is then placed into a bag 3 consisting of metal such as aluminum and a commercially available oxygen absorbent 4 of iron powder is placed in this bag 3 which is then packed under vacuum or complete displacement with an inert gas such as carbonic acid gas. Therefore, the container 1 requires a sufficient heat resistance to withstand the retort and boil sterilization and the lid 2 requires the same heat resistance as the container and the ability to seal the container 1. The bag 3 is so formed as to completely exclude gas such as oxygen gas, water, etc., which degenerate the shelf life of the contents A.

Abstract: PURPOSE:To prevent wafers from adhering closely onto a rubber plate at the time of ion implantation by performing ion implantation with wafers of semiconductors being put on the rubber plate with a fixed form of linear or curved grooves which is sticked onto a pedestal on a rotating disc. CONSTITUTION:In an apparatus in which wafers of semiconductors 6 are set on a plural number of pedestals 4 arranged to be on the same circumference 5 of a disc 1, for ion implantation into wafers 6 to be performed, while the disc 1 being rotated, a fixed form of linear or curved grooves 14 are formed on the surface where the wafers 6 are put on, as in shown by broken lines, using the pedestal 4 sticked by a silicon rubber plate 7.

Patent JP-S62196972-A (JP)
Title: Original reader
Inventor: SASAKI HIROSHI
IPC: H04N1/04
Filed: 1986-02-24
Abstract: PURPOSE:To attain the automatic control of the photodetecting level at an approximately fixed value regardless of the brightness on the surface of an original, by controlling the timing cycle to read the detection signal out of a 1-dimensional or 2-dimentional array of storage-type photodetecting elements in response to the brightness on the original surface. CONSTITUTION:A shift register 17 functions to control the output timing of the detection signal of a photodetecting element array 5b and is shifted by the timing of the clock pulse CP delivered from a VCO 18 to deliver the output signal from the corresponding element of the array 5b. Then the natural light L1 is made incident on a luminous intensity sensor 3 consisting of a phototransistor PTO and therefore the voltage VO is produced at the terminal of a resistance RO in response to the quantity of the light L1. The VO is increased as the light quantity is increased and the originating frequency of the VCO 18 is increased with the cycle of the pulse CP shortened respectively. Thus the shifting time interval of the register 17 is shortened. Then the voltage VO is reduced when the luminous intensity is reduced. Thus the originating frequency of the VCO 18 is reduced and the register 17 is shifted at a long time interval.

Abstract: PURPOSE:To prevent creation of excessively large strain in a rare-earth magnet by molding a rare-earth magnet material into a shape of a final product by itself, then hot molding the rare-earth magnet material together with a mating member or a material for the mating material into the final shape, and securing it to the mating member simultaneously with the final molding process. CONSTITUTION:A rare-earth magnet material 12 and a material for a mating member are molded into predetermined shapes, respectively, by a cold molding process. These compacts are combinded with each other to provide an integrate body, which is subject to a final molding process. More particularly, the rare-earth magnet material 12 is molded into a shape having a cavity at the center, while the mating member material is molded into a shape corresponding to the cavity. The latter compact is fitted in the former one to provide the integral body, and the integral body is put in an extrusion molding die. An extruding punch is applied to the mating member material compact located at the center and the integral body as a whole is extrusion molded into a ring shape 26. During the extrusion molding, it is the material for the mating member that is in direct contact with the extruding punch and subject to large strain. Accordingly, the rare-earth magnet material 12 is not subject to very large strain and hence can be prevented from being broken.
