Title: Solar energy capturing device
Inventor: SAWA MICHIO
IPC: D06F58/00
Filed: 1978-06-18
Abstract: PURPOSE: To eliminate inconveniences such as separate installation of heat receiving spaces, increased number of steps, low concentration magnifications, etc., make the device thinner, make  possible home position fixing and obtain high temperatures by using the special unit fly eyes'  lenses, using only the front hemispheres in collecting light and using the rear hemispheres as focal  planes.  
     CONSTITUTION: Sunlight incident to a glass spherical body 1 of a refractive index 1.91 focuses at  the portion close to the surface of its rear hemisphere. Such microspheres are laid as unit fly eyes'  lenses in one layer and the individual spheres are mutually bonded at the portions unexposed to  light collection, whereby a fly eyes' lens structure 2 is formed. The portions on the back side  which become focal planes are sandblasted to a rough surface and a heat-ray absorbing coating  film mainly composed of iron oxide is applied thereon to finish a hot point type heat collecting  sheet 2. A sheet 5 which is non-transparent to heat rays, mutually penetrated comb-tooth-form  partition plates 3, 4, hot point type heat collecting sheet 2, comb-tooth-form partition plates 3, 4  and sheet 6 which is non-transparent to heat are superposed in this order. Where the upper and  lower partition plates overlap by leaving the outlet and inlet 7, 8 of heating medium, the respective materials are bonded to provide the crooked paths for the heating medium.

Abstract: PURPOSE:To enable the yield of desired photoelectromotive forces by blocking surface current flowing through each photovoltaic array by a method wherein the photovoltaic arrays are surrounded by surface-current blocking regions. CONSTITUTION:The surface-current blocking regions 29 are formed by surrounding each photovoltaic 20-24 by removal of Si3N4 films formed on the surfaces of isolating regions 28. Since the regions 29 are thus provided, the surface current having flown through each array 20-24 does not flow, and a desired photoelectromotive force can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide an image display capable of displaying change in water surface in a virtual three-dimensional space more realistically. SOLUTION: A program to display a three-dimensional image of the water surface is read (S1). A water object formed by arranging plural wave objects constituted of two polygons is set in the virtual three-dimensional space (S2, S3). A sticking position of texture as patterns of the water surface is set at a position shifted for the wave objects (S4). A visual field image is generated by sticking the texture to the wave objects projected on a two-dimensional space (S5, S6). The visual field images to be successively generated by steps S3 to S6 are successively displayed (S7, S8). Thus, distortion of the texture is changed at the boundary between polygons of the wave objects in accordance with changes of the sticking position of the polygons of the wave objects and the realistic state of the water surface is displayed.

Title: Drier
Inventor: IMAI KOICHI
IPC: F26B9/06
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To increase the durability of a filter element by arranging a filter member so as to separate between a gas intake hole and gas outtake hole compressing in a gas compression chamber and feeding the gas purified by means of the filter member to nozzles from a gas discharge outlet, relating to a drier to dry washed hands. SOLUTION: When matter to be dried is put inside an insertion part 29, high-pressure air blows out from nozzles 27 and the matter to be dried dries in a short time. In this device, the air purified by a filter member 22 is blown off at a high pressure and the air-intake surface of the filter member 22 is arranged in parallel with the shaft of an air intake hole formed on a parting strip 15. As the air-intake hole faces to a parting strip 16 which is the bottom plane of a filter chamber 18, the impact caused by pressure which is generated when a blower 20 is initiated, is transmitted from the air-intake hole to the filter chamber 18 and comes into contact with the parting strip 16.  Further, the impact is dispersed in an extensive space and the filter member 22 is prevented from being damaged as the pressure is slackened and is applied onto the spatial inner surface of the filter member 22.

Abstract: PURPOSE:To eliminate a channel stopper for displaying the characteristics of an element and the element isolation in high reliability by a method wherein, after forming element isolating regions, wells are formed for enabling the concentration in wells and that in the groove bottom to be controlled independently. CONSTITUTION:Grooves are formed in a P type silicon substrate 101 using e.g., photoresists 102 as masks. First, the upper corners of the grooves are chamferred by oxidizing the silicon substrate wherein the grooves are formed in oxidizing atmosphere. Secondly, a CVD oxide film 105 as an insulating film in thickness larger than the depth of the grooves is formed on the surface of the silicon substrate to be coated with a high molecular resin film 106. Thirdly, the high molecular resin film 106 and the CVD oxide film 105 are etched away but the latter film 105 is to be left in the grooves. Fourthly, e.g., a boron 103 is ion-implanted as an impurity in different conductivity type from that of the silicon substrate and then phosphorus 107 is ion-implanted as another impurity in different conductivity type from that of the boron 103. Finally, the silicon substrate is thermal-diffused in nitrogen gas atmosphere to draw the specified concentration profile.

IPC: F16C13/00
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To simultaneously realize weight reduction and high hardness by providing a double layer structure composed of a white iron structure having a highly hard cam surface and a graphite structure having a soft inner wall of a central hole. SOLUTION: A chilled cast iron hollow camshaft for an automobile engine is formed as a double layer structure composed of a white iron structure 3 having the highly hard outer periphery of a cam part and a graphite structure 5 having a soft inner wall part of a hollow hole 4 by inclusion casting of a hollow core. The shaft end is formed so as to have a matrix softer than the graphite structure 5 and excellent in cutting performance. Thus, casting takes an annealing method of placing a heating core or a pad in an end part. Thus, the graphite structure 5 can be sufficiently exhibited by using the hollow core as a core. Graphitization of this part is promoted further by arranging the heating core in the end part, and a soft matrix further transformed into ferrite can be obtained.
