The invention provides a process for producing a modified conjugated diene based polymer which attains favorable interaction between a rubber component and carbon black and/or silica, thereby improving dispersibility of the fillers, and which exhibits excellent properties such as heat-buildup-suppressing performance, fracture characteristics, and wear resistance; a modified conjugated diene based polymer produced through the process; a rubber composition containing the diene polymer; and a tire produced from the rubber composition and exhibiting the above properties. The process for producing a modified conjugated diene based polymer includes a step (a) of reacting a silicon compound with a conjugated diene based polymer having an active end so that the reaction takes place at the active end, the silicon compound having a protected primary amino group in the molecule thereof and a bi-functional silicon atom to which a hydrocarbyloxy group and a reactive group are bonded, to thereby modify the active end, and a step (b) of performing condensation reaction which involves the compound having a bi-functional silicon atom, in the presence of a titanium compound serving as a titanium-based condensation-accelerating agent.

A method for collecting a liquid surface residual film floating on the surface of the liquid after transfer, and a transfer tank that includes a film holding mechanism, provided at inner sides of both right and left side walls, for holding both sides of the transfer film and conveying the transfer film to an immersion area. When a film that is no longer needed after the transfer is collected, dividing means divides the liquid surface residual film so as to split the liquid surface residual film in a longitudinal direction of the transfer tank before the object is removed from the transfer liquid, and the divided films are moved closer to the both side walls of the transfer tank. At the side wall portions, the film holding mechanism is canceled, and from this canceled portion, the divided liquid surface residual films are discharged out of the tank.

The subject of the present invention is to provide a steam generator constructed small in size. A steam generator 20 of the present invention is composed of a cylindrical steam generation vessel 30 having a steam generation portion 31 formed to store an amount of water for generating steam and a steam passage 32 formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion, a heater element 40 disposed within the steam generation vessel 30, and an induction heating coil wound around the periphery of the steam generation vessel 30 for energizing the heater element. The heater element 40 is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage. In the steam generator 20, a steam discharge duct 70 is mounted on the upper end of the steam passage 32 for receiving the steam spouting upward from the steam passage to discharge it in a lateral direction such that drops of hot water adhered to a ceiling surface of the discharge duct fall and circulate into the steam generation part 31.

To provide a game device for presenting to a player inputting the amount of operation while utilizing a gauge, the length of a gauge which corresponds to a desired amount of operation. In a game device in which an object placed in a virtual three dimensional space is moved by a distance according to the displayed length of the gauge when the player carries out a predetermined operation, a target position to which the object is going to be moved is obtained (S102), a distance between the target movement position and the present position of the object is calculated (S103), and the length of the gauge corresponding to the calculated distance L is calculated based on the distance L (S104). Then, the target length of the gauge is presented based on the calculated length of the gauge (S105).

A process for producing an oral preparation containing a first water-swellable gel-forming layer and a second water-swellable gel-forming layer as outermost layers, a medicine being sealed in an inner space formed by bonding the periphery of the first water-swellable gel-forming layer and the periphery of the second water-swellable gel-forming layer either directly or via an adhesive layer, the process including (a) a step of forming a first water-swellable gel-forming layer, (b) a step of forming a recess in a predetermined area of the first water-swellable gel-forming layer, (c) a step of filling the recess with a medicine to obtain a medicine-containing body, and (d) a step of forming a second water-swellable gel-forming layer over the medicine-containing body directly or via an adhesive layer so that the first water-swellable gel-forming layer and the second water-swellable gel-forming layer are bonded around the recess, and a process for continuously producing the oral preparation are disclosed. According to the above process for producing an oral preparation, an oral preparation in which the medicine is completely masked so that the medicine can be administered without a problem of bitterness and odor of the medicine can be efficiently produced without causing the medicine to deteriorate due to heat history, without a loss of the medicine, and without a limitation to the amount of the medicine to be added.
