Title: Regeneration of adsorbent for drying inert gas
Inventor: IHARA SATOSHI
IPC: B01D53/26
Filed: 1983-08-29
Abstract: PURPOSE:To regenerate an adsorbent under energy saving without taking out a packing layer, by moistening an adsorbent packing layer of which the capacity is lowered while bringing the moistened layer into contact with water to remove a solid salt component. CONSTITUTION:In performing the dehydration of inert gas for shielding the tank provided in a tanker, when the pressure loss of an adsorbent packing layer 2 exceeds predetermined pressure, the supply of oil 13 is stopped and wet air is passed through the absorbent 2 from a blower 14 through pipes 19, 6 to sufficiently moisten the adsorbent 2. Subsequently, a valve 26 is opened to introduce washing water from a pipe 4 and water is sprinkled over the adsorbent 2 from spray nozzles 5. The solid salt component adhered to the adsorbent particle 2 is dissolved and flowed out from a pipe 7. After washing is finished, drainage is performed under gravity and air is sent from an air introducing pipe 30 through a valve 29 to preliminarily dry the adsorbent 2 and, thereafter, air with a temp. of about 150-200 deg.C is sent to dry the same and exhausted from a gas outlet 8.

Title: Semiconductor laser device
Inventor: TANAKA TOSHIO
IPC: H01S5/00
Filed: 1979-12-05
Abstract: PURPOSE:To obtain a semiconductor laser having a high confining effect in excellent controllability by a method wherein a distance of diffusion of impurities into a crystal is skillfully controlled, and an active region confining an active layer from the three directions is formed. CONSTITUTION:The locations of P-N junctions are formed in diverged shapes by lowering the concentration of the carriers of an N type AlGaAs layer 12 at the lower side more than P type AlGaAs layer 14 at the upper side between the N type and the P type layers 12, 14 holding both sides of an N type GaAs active layer 13. A location of a P-N junction of the N type GaAs active layer 13 is also formed conforming to the P type AlGaAs layer 14 on the N type GaAs active layer 13 by changing the concentration of carriers and utilizing the difference of the speed of diffusion of AlGaAs and GaAs. Thus, since the P-N junctions contact with an active region 17 in the two directions, an extent of currents in the N type active layer 13 is limited from the three directions, threshold value currents are low, and the oscillation of a single mode is easily obtained.

IPC: C23C2/00
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent peeling of a rubber roll during use by fitting a sleeve-like unvulcanized rubber on a roll core metal, pressing and vulcanizing the rubber in a die. SOLUTION: An unvulcanized rubber formed into a sleeve, namely, into a center cylinder is fitted on a roll core metal 2 in such a manner that the center axis of the cylinder coincides with the center axis of the roll core 2 and that the inner surface of the cylinder of the sleeve rubber 1 covers the outer surface of the roll core metal 2. Then the rubber is pressed and vulcanized by using a die press 3. Thereby, air trapped and remaining between the roll core metal 2 and the rubber 1 can be removed, which prevents peeling on the adhesion face between the roll core metal 2 and the rubber 1 when the rubber roll is used. Moreover, air remaining in the rubber can be removed by pressing and vulcanizing, which makes the rubber itself dense to have higher strength and prevents peeling in the rubber part when the roll is used.  By vulcanizing in a die press, wear resistance of the rubber roll can be improved.
