IPC: F23C6/04
Filed: 1993-11-26
Abstract: PURPOSE:To enable energy recovery and heavy metal separation in the gasification of a superheavy oil by installing, separately from a gasification oven for partially oxidizing the oil, an oven for burning or gasifying unreacted residues and deposits and a water bath for an exhaust gas on the downstream side. CONSTITUTION:A superheavy oil 10 (e.g. a petroleum distillation residue) is spouted together with air 11 in a ratio of the oil to air of about 0.35-0.45 into a gasification oven 1 and partially oxidized. After heat recovery, the resulting gas is filtered with a porous filter 3 to remove a solid component (char) and utilized for a gas turbine. The separated char is burned or gasified in another oven 6 with a different air ratio. When the char is gasified, a gas with 1,000kcal/kg or higher is obtd. and recovered through a line 14; in the case of burning, heat is recovered with a water wall 7 installed on the wall of the oven 6 and the combustion gas is fed back through a water bath 8 to the oven 1 as a heat source. Thus, the installtion of the burning or gasification oven 6 enables not only energy recovery from the char formerly disposed of but also removal of ash.

Title: Private branch exchange
Inventor: TAKASHIMA SHOICHI
IPC: H04Q3/58
Filed: 1991-11-13
Abstract: PURPOSE:To allow the private branch exchange to reply an extension terminal equipment in which communication of a kind based on setup information is available by providing a recognition means recognizing kind of communication and a discrimination means discriminating whether or not the extension terminal equipment is to be called to the private branch of exchange. CONSTITUTION:This private branch exchange is provided with a recognition means recognizing kind of communication based on call setting information transmitted from an ISDN 104 and a discrimination means discriminating whether or not an extension terminal equipment is to be called based on the comparison between the kind of the extension terminal equipment and the kind of the communication recognized by the recognition means. When the recognition means recognizes it that the kind of communication is talking, the discrimination means discriminates it that no setup information is sent to the extension terminal equipment for data communication. That is, an extension terminal equipment not available of the communication of the kind based on the setup information is not called. Thus, the deterioration in the communication efficiency due to the reply of the extension terminal equipment of such a kind is prevented.

Filed: 1990-11-02
Abstract: PURPOSE:To prevent stress from being accumulated at a contact part and prevent deterioration of a characteristic value by partially covering a part above the contact part between an impurity diffusion region and an Al wire with an insulation film which is made of a softer material than a cover film. CONSTITUTION:A p-type base region 2 consisting of a diffusion layer 3 and an n-type emitter region 3 are formed on a silicon substrate 1 and this n-type emitter region 3 is connected electrically and physically to an Al wire 5 which is formed on an insulation film through a contact hole. Then, a part above this emitter/contact part 4 is in a cover structure where it is partially covered with a material, for example a silicon oxide film 6, which is softer than a material of a cover film 7 which covers an entire chip surface, thus enabling stress which is accumulated at the contact part to be relaxed and deterioration of characteristics to be restricted.

Title: Sealing device
Inventor: KANDA TAKESHI
IPC: F16J15/3244
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To improve sealing performance by providing slits of a seal lip in such a way that the openings thereof are extended from a cross line of a sliding contact face and a sealed fluid side end face while inclining in the direction between a rotating direction of the other member and the fixed part direction, and providing these slits at least one each for lateral rotation of the other member so as not to intersect each other. SOLUTION: Several slits 6 obliquely extended from a sliding contact face are extended on the oil side end face 22a of a lip part 22 from points on a circle S of a cross line of the end face 22a and sliding contact face so as not to intersect each other. Taking account of the case of CCW rotation of a shaft 5, an opening of a slit 61 is extended from a point p1 on the circle S while a point on the shaft in contact with the point p1 is inclined in the direction between the rotating direction X and the fixed part direction Z1. A slit 62 is provided taking accout of the case of CW rotation of the shaft 5. At the time of CW rotation, the slit 62 is opened to generate pumping effect, and the slit 61 is closed to prevent the generation of pumping effect. At the stationary time, both slits 61, 62 are closed. Sufficient sealing performance can therefore be obtained in both rotating and stationary cases.
