Title: Apparatus for removing foreign matter
Inventor: SATO TAKESHI
IPC: B01D35/02
Filed: 1984-11-22
Abstract: PURPOSE:To dispense with a straight pipe part in a pipeline and to obtain the titled apparatus with small pressure drop by utilizing a water chamber whose opening area is large and wherein the flow velocity is low without using any drum bodies and removing foreign matter in the water chamber. CONSTITUTION:Water is charged usually from a pipe stand at the lower part of a water chamber 6, passed through a filter member 1, and discharged in the direction of a pipe bundle. In this case, foreign matter (a) mixed into water is stopped on the surface of the filter member 1 on the upstream side by the member. When foreign matter is removed, a valve 5 is opened to generate an extracting water flow due to the pressure difference between the pressure in the water chamber 6 and the end part of the pipe after the valve 5. Consequently, the water from the upstream side of the filter member 1 is obstructed temporarily by an extracting pipe 2 on the filter member 1 end side of the extracting pipe 2, external force for pressing the foreign matter (a) on the filter member 1 is released, and the foreign matter (a) is removed by the extracting water flow. By utilizing the action and moving the extracting pipe 2, the foreign matter on the whole filter member 1 can be removed.

IPC: G21C15/18
Filed: 1990-09-18
Abstract: PURPOSE: To make it possible to maintain a danger in an environment to the minimum limit by incorporating fusible metal in a fault assembly, and introducing cooling water into a dry well when a reactor core is fused. CONSTITUTION: In a nuclear reactor facility 100, a mounting support 114 supports a reactor vessel 104 in a dry well 106, and a fault assembly 112 coupled to a conduit 110 prevents the flow of cooling water 120 from a water reservoir 108 to the well 106 in a normal state. If a reactor core cooling system is faulted, the core is fused, corium of high temperature fused product substance is immersed into the vessel 104 to drop on the floor of the well 106, the metal contained in the assembly 112 is fused by the heat of the corium so that the reaction of the corium injected with the water 120 in the well 106 with concrete is suppressed. Thus, the gas pressure in the facility is maintained at an allowable level, making it possible to substantially avoid the danger due to the operator's carelessness and malfunction of a controller.

Abstract: PURPOSE:To contrive improvement in the uniformity of a semiconductor substrate by a method wherein the prescribed quantity of ions are divided into three parts, and they are implanted three times on the surface of the semiconductor substrate at the angle rotated one third with the vertical shaft as the center. CONSTITUTION:One third of the prescribed quantity of impurities of implantation is implanted three times at the angle rotated 0 deg., 120 deg. and 240 deg. on the vertical axis. By implanting ions three times as above-mentioned, the irregularity of layer resistance can be reduced to one third of 1.5-0.5% of the average value in the standard deviation when compared with a one-time ion implantation achieved with orientation flat (OF) fixed. Also, said irregularity can be reduced to the state in which almost no channelling effect is recognized. Besides, the three-time injection brings about excellent results not only for a substrate 100 but also for a six-time symmetrical substrate 111.

Abstract: PURPOSE: To prevent the deterioration of a hot-carrier resistance which is caused by the moisture present in an interlayer insulation film, in the semiconductor device having a MOS-type transistor. CONSTITUTION: After a MOS-type transistor having a gate electrode G1 is formed on the surface of a semiconductor substrate 10, a wiring layer 16 of a first layer is formed via an interlayer insulation film 14.

Title: Light-emitting diode array
Inventor: TOMINAGA MORIO
IPC: H01L33/56
Filed: 1988-09-30
Abstract: PURPOSE:To obtain a uniform luminance distribution by forming the surface of a transparent synthetic resin film covering arrayed light-emitting diode devices on a light collection surface. CONSTITUTION:The surface covering a light-emitting diode device 2 is formed on a light collection surface which collects light emitted from the light-emitting diode device 2 in front. Hence, light emitted from a light-emitting diode device 25 which emits a strong light particularly travels through a synthetic resin film 4 and travels radially in many directions from a non-light collection surface 46. Light which advances obliquely is totally reflected on the non-light collection surface 46 and advances toward a substrate 1. Most of the light are absorbed here, and some of it is reflected again on the substrate 1 and advances obliquely from the non-light collection surface 46. As a result, if this array is seen from the front, the light emission of the light-emitting diode device 25 is seen in the same brightness as that of other light-emitting diode devices 2 despite the fact that the light emission of the device 25 is stronger than that of the device 2, and the luminance distribution becomes uniform.

The connecting hole 4 is filled with the high-melting-point metal film 5. Then, treatment for increasing the area of the exposed surface of the high-melting-point metal film is performed. Then, an upper wiring layer 6 which is connected to the conducting region 2 through said high-melting-point metal film 5 is formed on the interlayer insulating film 3. For example, the tungsten film 5 is selectively grown in the contact hole 4 by a silane reduction method. Then, the device is exposed to Cl2 gas for forming WClx having high vapor pressure for about one minute. Thus a part of the surface of the tungsten 5 becomes WClx. Then SF6 is supplied as etching gas, and etching is performed. Then irregularities are formed on the tungsten 5. Thereafter, the upper wiring film 6 is formed.
