IPC: E04D1/30
Filed: 1993-05-12
Abstract: PURPOSE:To prevent ridge members from falling away out of a roof face due to corrosion of a spacer member, by sticking the blocking material in a clearance between the ridge members and the roof face and fixing the ridge members at a position different from the position of the spacer member. CONSTITUTION:A substrate material 14 and roof tiles 16 are laid down in this order so as to cover the ridge on a couple of sheathing roof boards 12 inclined in the directions opposite to each other. Ridge tiles 18 are arranged as ridge materials for covering a roof top part between the uppermost parts of respective roof tiles 16 and provided with legs 18a to form a space between the ridge tiles 18 and respective roof tiles 16.

Title: Pattern formation method
Inventor: HATADA KENZOU
IPC: H01L21/3205
Filed: 1977-09-12
Abstract: PURPOSE:To enhance the pattern formation yield by having lift-off via the solution with which the metal film is removed along with the sensitive resin under the metal film, and then to stabilize the manufacturing processes by increasing the tolerance of the correlation between the resin and the metal film thickness. CONSTITUTION:Pattern 22 of the sensitive resin is provided to substrate 21 with which the element formation is through, and then the substrate is covered with metal film 23 and 23' to make corner 24 thin. Then the substrate is soaked into the solution to dissolve both the metal and resin, and the ultrasonic vibration of about 29KC is applied. As a result, resin 22 is melted away, and only film 23' remains. Thus, a pattern is formed. With this method, the metal film pinhole is enlarged positively at the pattern stage part, and at the same time the resin is melted away. As a result, a minute pattern can be formed with a high accuracy and high yield. Furthermore, the so-called tolerance can be increased between the resin film and the metal film, thus ensuring the steady manufacturing processes as well as a  high production yield.

Filed: 1987-05-06
Abstract: PURPOSE:To feed paper securely, if it is thick, by providing a constitution where a plurality of pressure rollers are arranged in a paper feed direction and the rotary shafts of these pressure rollers are connected to a belt respectively. CONSTITUTION:Both front and rear pressure rollers 1a, 1b are provided with pulleys 3a, 3b respectively on the ends of rotary shafts of the rollers, and a belt 4 is provided across these pulleys. Paper 7 is inserted through the rear pressure roller 1b side, and when paper enters between the rear pressure rollers 1b and a platen 6, the rear pressure roller 1b is separated from the platen 6, resulting in the loss of capability to feed paper 7 of the rear pressure roller 1b itself. However, a paper feed power is conveyed to the rear pressure roller 1b through the belt 4 due to the contact with the platen 6 of the front pressure roller 1a, thus assuring secure feeding of the paper 7.

Filed: 1982-06-25
Abstract: PURPOSE:To improve abrasion resistance and service life, by providing a coating layer conisting of chromium on the surface of an electrode for resistance welding to be brought into contact with a member to be welded. CONSTITUTION:A chromium coating layer 2 is formed on the forward end part of an electrode 1 in the range wider than the contact surface 21 with a member to be welded.

Title: Injection molding method
Inventor: NAKAMURA TSUTAE
IPC: B29C45/17
Filed: 1988-05-09
Abstract: PURPOSE:To compensate the warpage at cooling by a method wherein dies are opened before the solidification of the material in a cavity and, after that, the molded item is cooled down under the state being warped reversely. CONSTITUTION:Dies are clamped under pressure by advancing a mold clamping ram 20. Next, by actuating a stock injecting mechanism 3, molten molding material is injected and filled in the cavity of the dies. The dies are opened before the solidification of the material in the cavity by retreating the mold clamping ram 20. At the same time, a molded item 4 is somewhat ejected so as to be cooled down while being forcibly warped reversely by advancing ejector plates 24 and 26 by one step. At this time, during the cooling-down and solidification of the molded item, warpage develops warpage, which ejects the molded item and compensates the forcibly developed reverse warpage, resulting in making the warpage throughout the whole molded item 4 extremely small. When the cooling and solidification of the molded item 4 completes, the ejector plates are further advanced in order to take the molded item 4 out of the dies.

Title: Triangle dividing system of closed pattern
Inventor: KAJIURA TOSHINORI
IPC: G09G5/36
Filed: 1984-06-01
Abstract: PURPOSE:To decrease the number of using memories and to improve the data transfer performance by showing the data on the coordinate positions of a closed pattern at the apex positions of some continuous triangles. CONSTITUTION:When a closed pattern is divided into triangles and stored, the triangles adjacent to each other on a memory are also adjacent as patterns with a side shared in many cases. In such a case, two of three apexes are equal between both adjacent triangles. Therefore it is possible to omit the data corresponding to two apexes among three of the low-order triangle on the memory. Thus a command showing the continuous triangles and one apex display a triangle. For instance, flags 50-52 are all set at ''0'' with a command 31 which defines first a triangle. While two of flags 50-52 is equal to 1 with the rest one set at ''0'' with commands 32-35 which define a trinangle that shares two spexes with the immediately preceding triangle. Then one of flags 50-52 is equal to ''0'' with the rest wo set at 1 with a command that defines a triangle sharing an apex with the immediately preceding triangle.
