Title: Energy saving method in building and external wall construction
Inventor: TAKAHASHI KENJI
IPC: E04B1/76
Filed: 1995-01-25
Abstract: PURPOSE: To perform energy saving in the summer season and the winter season at the same time. CONSTITUTION: On the surface outside a tile main body 200, a sunlighit absorbing covering material 250 and hood members 270 are provided. The sunlight absorbing covering material 250 absorbs more sunlight compared with the tile main body 200 and efficiently raises temperature. The hood members 270 insulate the sunlight and have higher heat insulating ability compared with the tile main body 200. In the summer season when the sun is high, the hood members 270 insulate the sunlight so as to reduce a cooling load, in the winter season when the sun is low, the sunlight is not insulated by the hood members 270, but irradiated on the sunlight absorbing covering material 250, and hence the tile 20 is warmed up so as to reduce a heating load.

Title: Electronic component packaging structure
Inventor: SUZUKI MITSUAKI
IPC: H05K1/18
Filed: 1988-02-15
Abstract: PURPOSE:To alleviate a thermal stress without deteriorating a property with respect to a superhigh speed signal by a method wherein an electronic component is fixed in such a manner that its lead is set apart from a foot print by a specified length and the lead and the foot print are soldered to each other by melting a molded solder piece interposed between them. CONSTITUTION:Each lead 22 is separated from the opposed foot print 28 formed on a printed board 24 by 1mm or so. A thick solder piece 29 is heaped on the foot print 28 occupying the space between the foot print 28 and the lead 22 and connects electrically each lead 22 with the foot print 28 opposed to the lead 22. The solder piece 29 can be slightly deformed so as to make its upside and underside slide in opposite directions respectively, therefore the thermal expansion difference between a package 21 and the board 24 is offset by the deformation of the solder piece 29 at a cyclic heating. By these processes, a thermal stress acting on the connecting part can be alleviated, properties of an electronic component are free from the adverse effect caused by a lead, so that the above-mentioned packaging structure can be applied to a superhigh speed signal circuit device with effect.

Abstract: PURPOSE: To prevent an occurrence of work distortion due to contraction of a metallic thin plate after work, by providing preliminarily minute rugged parts near the work line for the high-temperature heating work of the metallic thin plate.  
     CONSTITUTION: For welding or the like between metallic thin plates 1 and 2, a regular form is given to welding line 3, and fine and smooth wave-form rugged parts 8 are provided continuously near welding line 3 along this line by the press work or the like. Surface dimensions of thin plates 1 and 2 in part 5 near welding line 3 are extended to a degree adapted to contraction after welding.

That is, rugged parts 8 are deformed with tensile stress in the face sufficiently smaller than buckling stress of thin plates 1 and 2 and are stretched into a plane. As a result, thin plates 1 and 2 have a plane form within the allowable range after welding.

IPC: C23C14/54
Filed: 1988-02-15
Abstract: PURPOSE:To make it possible to control and monitor the film formation in atomic layer order by a method wherein a spectrochemical analysis of photoelectron is conducted simultaneously with the formation of the film. CONSTITUTION:A film-forming material 7 is scattered on a substrate material from the source of vapor deposition, and a thin film is grown on the substrate. Simultaneously with the above-mentioned growth of film, a spectrochemical analysis of photoelectron is conducted by projecting X-rays or a radiant light from the source of X-rays or the source of radiant light 4, and the variation with time of a spectrum is monitored. The first peak only appears when an atomic layer B is formed, its intensity is increased with the formation of said atomic layer, and after the 1-atomic layer B has been formed, the second peak appears when the formation of a 2-atomic layer D is started. Accordingly, the monatomic layer B thin film can be formed by stopping the growth before the appearance of the second peak. As a result, the control and monitoring of the formation of a film in the atomic layer order can be conducted.

Title: Wet motor type pump
Inventor: YANAI RYOICHI
IPC: F04D7/08
Filed: 1986-02-18
Abstract: PURPOSE:To prevent water leakage by furnishing a weak point pin, which supports a thrust bearing on a pump shaft and collapses when a load over a certain value is applied, and installing a sealing device which checks liquid flow through mutual linkage when said weak point pin has collapsed. CONSTITUTION:If water leak has occurred at a heat-exchanger 9 and primary cooler pipings 18, 19 or a motor 4, the pressure in the motor casing 5 becomes lower than the pressure in a reactor vessel 10. At this time, a load due to pressure difference is applied to the pump shaft 6 in addition to its own weight to cause collapse of a weak point pin 21. As a result, the sealing surface 24 of the pump shaft 6 is detained with the sealing surface 22 of a stretch tube 16 to allow checking of high-temp., high-pressure water from flowing in from the reactor vessel 1 side to the pump casing 5 side. While wet motor type pump 3 is at a standstill in normal condition without water leak, impeller 12 and pump shaft 6 are supported by the weak point pin 21 through a lower thrust bearing 11.
