Title: Sleeper
Inventor: SAKURAI YOSHIKI
IPC: E01B3/20
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To increase the capacity by protruding downward a resistant plate at the ends of a metallic box-form sleeper opened at the bottom and making larger toe surface area or the resistant plate covered with ballast in the deeper part than that in the shallower part. SOLUTION: This resistant plate 15 is made to shape such a trapezoidal form that the width becomes larger as it goes to the depth in the ballast and hence, the area becomes larger. The plate 15 is made larger in the surface area where the resistance from the ballast gets large, to increase the resistant efficiency against the lateral pressure and prevent the increase of the weight of sleeper 1. When taking the strength of the plate 15 into consideration, it is not desirable that the plate size becomes larger as the plate goes to the depth but it is made breadthwise larger and hence, the size does not become larger in the depth direction. In this way, a required capacity against lateral forces can be obtained and further, the workability is improved.

Title: Color cathode-ray tube
Inventor: KAMATA AKIHIRO
IPC: H01J29/02
Filed: 1994-03-30
Abstract: PURPOSE:To prevent the color purity of a color cathode-ray tube from deteriorating at the time of operation by causing a stud pin to offset the thermal expansion of a spring, regarding a color cathode-ray tube assembled so as to fix and support a shadow mask body structure. CONSTITUTION:A stud pin is formed out of bimetal where a material member 7a having a small thermal expansion coefficient and another material member 7b having a large thermal expansion coefficient are jointed to each other at a plane vertical to the displacement direction of a spring 5 due to thermal expansion. In this case, when the temperature of a shadow mask 3 rises during operation, thermal conduction from a frame 4 to the stud pin 7 takes place via the spring 5, and the spring 5 is displaced along the arrow direction of a dotted line, due to thermal expansion. The stud pin 7 made of the bimetal, however, is deformed along the arrow direction of a solid line, due to a thermal expansion coefficient difference between the members 7a and 7b. Thus, the displacement of the spring 5 is offset and the position of a shadow mask body structure 6 relative to a face panel 1 can be maintained without any change.

Abstract: PROBLEM TO BE SOLVED: To automatically and effectively acquire the information on an unknown object based on its image by retrieving an image data base based on the retrieval object image and also the environmental information defined when the object image is acquired. SOLUTION: A user photographs an object via a camera part 1 to retrieve an unknown object. If the composition of the photographed image is inappropriate, the user corrects the composition via a composition change part 3 to acquire an image of optimum composition. Then the user cuts out the contour of the optimum image shown at a display part 14 via a pen input part 4 and extracts the image at an image extraction part 5. The extracted image is converted into an object binary image at an object image conversion part 6. Meanwhile, the object size is calculated from the photographed image, and the data image acquired by retrieving an image data base 11 is converted into a binary image at a data image conversion part 12 as long as the data image has a size equal to the object. Then the binary image is compared with the object binary image at an image comparison part 10. When the highest similarity is decided between both binary images, the data are extracted from the acquired image. Then the retrieval result is outputted as an image via a result display control part 13.

Title: Manufacture of semiconductor device
Inventor: SHIMODA KOUICHI
IPC: H01L23/522
Filed: 1984-03-30
Abstract: PURPOSE:To prevent short circuits along a step in a multilayer device between its lower and upper conductive layers and disruption of wirings belonging to the upper conductive layer by a method wherein the entire surface of a second insulating layer is flattened by forming a P-doped insulating layer on the surface of the first insulating layer. CONSTITUTION:On a semiconductor substrate 11 covered with an impurity- diffused layer 12, a first insulator 13 of PSG or the like is formed. An insulating layer 14 is then formed densely diffused with P by the ion implantation or diffusion method. A conductive layer 15a for contacts and a conductive layer 15b for wirings are formed. A second insulating layer 16 is formed of P-glass or an oxide by CVD under a normal pressure. Next, a second conductive layer 17 is formed. The existence of the P-doped insulating layer 14 on the first insulating layer 13 accelerates the growth of the second insulating layer 16, which alleviates the inclination C in the second insulating layer 16 at a step. This design greatly reduces the possibility for the second conductive layer to be formed excessively thin or of disruption thereof, which contributes to the prevention of short circuits between the first and second conductive layers.
