Title: Fuel cell
Inventor: MAOKA TADANORI
IPC: H01M8/02
Filed: 1986-05-07
Abstract: PURPOSE:To obtain an electrolyte layer and a catalyst layer formed on an oxidizer electrode of a fuel cell, which is stable even at a high temperature, enhances the oxygen solvability, and promotes the cathode reaction, by containing carbon fluoride in the electrolyte. CONSTITUTION:Silicon carbide as an electrolyte-resisting micropowder, and phosphoric acid are put in a beaker, stirred up sufficiently while being depressur izing, heat-treated in a thermostat, and then depressurized and degassed while being cooled naturally. Then, carbon fluoride is added and the mixture is stirred up. After that, polytetrafluoroethylene dispersion solution is added gradually, stirred np, heat-treated in a thermostat, cooled naturally, stirred up at a high speed under the depressurized condition, and an electrolyte layer holding a paste-form electrolyte including carbon fluoride is acquired. This electrolyte layer is spread over the anode catalyst side of an electrode, a cathode is piled thereover, and unified and pressed to make a unit cell. Since such a fuel cell has an electrolyte layer with fluoric acid as the base, or the catalyst layer formed on the oxidizer electrode, which is added with carbon fluride, the oxygen density around the cathode is increased, the oxygen reducing reaction is speeded up, and the cell property is improved.

Title: Sedimenting separator
Inventor: MOURI TAKUO
IPC: B01D21/24
Filed: 1980-07-29
Abstract: PURPOSE: To effectively recover small floc pieces, fine particles, etc., present in separated water as well as keep the amount of separated water to be discharged per unit time in the same as in the conventional cases by a method wherein radial water-collecting troughs and circumferential water-collecting concentric troughs are provided an almost the same level each other.  
     CONSTITUTION: On almost the same level as radial water-collecting troughs 3, a large number of circumferential water-collecting concentric troughs 11 are provided, which are communicated only to the radial water-collecting trough 3. Thus, since water does not fluid rapidly in the circumferential water-collecting troughs 11, fine particles or small floc pieces floating in the separated water become liable to settle in the circumferential water-collecting troughs 11, whereby improving not only the recovery efficiency of fine particles but also the turbidity of the separated water. In addition, since the number of the radial water-collecting troughs 3 are the same as in the conventional apparatus, the amount of the separated water to be discharged per unit time and also the amount of raw water to be treated can be kept  at the same as in the conventional apparatus.

Title: Formation of soi film
Inventor: KOYAMA KENICHI
IPC: H01L21/02
Filed: 1988-04-28
Abstract: PURPOSE:To execute a laser annealing operation by a method wherein a thin film with a film thickness capable of increasing a laser beam absorption rate is formed on a semiconductor thin film on an uneven device in order to make a heat balance uniform inside the semiconductor thin film. CONSTITUTION:A film thickness of a silicon oxide film 2 on a gate electrode 3 is thin; it is thick on source-drain regions; the thick ness of the silicon oxide film 2 in a device isolation region is maximum. A silicon oxide film 8 and a silicon nitride film 7 are formed on a region 5 in a polycrystalline silicon film 4; a film thickness of these two thin films is set in such a way that about 1.2times a laser beam in a region 9 are incident on the region 5 in the polycrystalline silicon film 4. The thermal nonuniformity in the polycrystalline silicon film 4 due to a heat accumulation effect is offset by a difference in an incidence amount of the laser beam. As a result, a whole region of the polycrystalline silicon film 4 can be made monocrystalline by a laser annealing operation under an identical condition. By this setup, even when an interlayer insulating film is formed on an uneven device, a semiconductor thin film on it can be easily made uniformly monocrystalline by the laser annealing operation.

Title: Insulation gate transistor
Inventor: YOSHIDA ISAO
IPC: H01L29/10
Filed: 1984-05-25
Abstract: PURPOSE:To obtain the MOST having the characteristics of high withstand voltage and low ON-resistance by a method wherein the depth of the first impurity layer is made larger than that of the second impurity layer by providing the former by surrounding the latter. CONSTITUTION:A material with an n type low concentration impurity layer 2 formed on an n type Si substrate 1 is used as the semiconductor substrate. In a cell part A, a polycrystalline Si layer is formed on a gate insulation film 3 and then processed into a gate electrode 4, and a base layer 6 is formed by using the electrode 4 as a mask. This base layer 6 is a p type impurity region and is e.g. 10mum deep, whereas a source region 7 formed in the layer 6 is an n type high concentration impurity layer and is e.g. 2mum deep. In the periphery B, p type impurity layers 5 and 5' are e.g. 20mum deep and formed so as to surround the base layer 6 of the cell part A. This construction reduces the dimension of the base layer 6 because the depth of the layer 6 is smaller than the impurity layer 5, resulting in the improvement in current density in the cell part A and to the reduction in ON-resistance.
