Title: Confidential document producing method using diazo photosensitive paper
Inventor: KOMURA SHUJI
IPC: G03G21/00
Filed: 1987-04-21
Abstract: PURPOSE:To produce a confidential document by which true information is difficult to leak, by copying the true information by a toner of the same color onto a photosensitive layer forming surface of diazo photosensitive paper, and also, copying dummy information by the toner of the same color, and forming the third information on the other face of the diazo photosensitive paper. CONSTITUTION:On an original placing table of an electrophotographic copying machine, the first original (true information) is set and copy is executed, and on a photosensitive layer forming surface of diazo photosensitive paper used as transfer paper, a white toner image corresponding to an original image is formed. As for an obtained copy, an image is formed by a white toner on white diazo photosensitive paper, and an image information part becomes difficult to be decoded. This copy is further used as transfer paper, and the second original (dummy information) is copied by a coloring toner. Also, the other face of the transfer paper on which the first and the second information are formed is used as a transfer surface, and the third original (dummy information) is copied. As for the toner used in this case, desirably, the toner having a high contrast to the transfer paper is used. In such a way, a confidential document can be produced.

IPC: A01K61/00
Filed: 1994-04-12
Abstract: PURPOSE:To fill a heavy matter into a tire to increase the weight of the tire, and constrain a number of the resulting tires by a net or fence to form an undersea setting matter. CONSTITUTION:A net 5 is formed so as to have a bag form gradually narrowed toward the rear according to the outer circumferential form in which tires 10 are combined. The housed tires 10 are constrained in such a manner as to be slightly movable but keep the form as the whole. Thus, a number of tires 10 can be arranged and held without mutually connecting the tires 10 nor mutually screwing the tires. Instead of the net 5, a box fence consisting of a frame material fitted to the outside of the tires may be used.

Title: Image display device and its manufacture
Inventor: NAKAMURA AKIRA
IPC: G02F1/136
Filed: 1989-04-20
Abstract: PURPOSE:To simplify a process by utilizing side etching of an insulation layer at the upper layer when forming a hole reaching a polycrystal silicon by etching. CONSTITUTION:A polycrystal silicon 2, NSG(Nondoped Silicon Glass) 3, and Pl-SiNx4 are accumulated on a crystal substrate 1 in sequence and a part for forming contact is subjected to patterning by a resist 7. Then, etching is performed by using 7% hydrofluoric acid solution. Etching rate of Pl-SiNx is faster than that of NSG so that Pl-SiNx is side-etched to a great extent when etching is performed. Thus, the side wall of a contact hole becomes slanted. By eliminating the resist 7, accumulating an ITO 5, and performing heat treatment, an ohmic contact is formed directly between the ITO5 and the polycrystal silicon 2 and then finally Pl-SiNx 6 of passivation is accumulated. In this manner, production process can be simplified by allowing direct contact between the ITO and polycrystal silicon.

IPC: F16L47/02
Filed: 1988-04-21
Abstract: PURPOSE:To eliminate difficulty in setting an energizing time by measuring the temperature of a plastic pipe joint so as to stop the energization when the temperature reaches a predetermined temperature. CONSTITUTION:A connecter 3 is provided with a connecter bushing 33, electrical wires 34 and a thermocouple 31 by which the temperature of a plastic pipe joint 1 is measured. The plastic pipe joint 1 is energized through the electrical wires 34 and a connector bushing 33, and a increased temperature of the pipe joint 1 is measured after several seconds elapsing. If an increased temperature is lower than a set increased temperature, the energization is stopped, but it is higher, the energization is continued. Further, when the temperature of the plastic pipe joint 1 comes to the set temperature, the energization is stopped. With this arrangement, it is possible to eliminate the control of energizing time, and therefore, it is possible to eliminate a difficulty in setting an energizing time. Further, it is possible to prevent inferior fusing since an abnormality during insertion of the connector 3 may be detected.

Abstract: PURPOSE: To provide a stock management system which can automate the stock management of received materials to save the labor needed for the stock management, to improve precision of the stock management and also to improve the productivity. CONSTITUTION: In a stock management system 1, a previous confirmation lot input processing part 7 registers the relation between a previous confirmation lot number and a material stock population related to the lot number when the previous confirmation lot number is put into an assembling process. After this registration processing, the data on relation between the preceding lot number and population are registered in a previous confirmation lot management file 20. At the same time, the material component of the material stock population is shifted from the receiving inspection pre-stock of the material part number related to the previous confirmation lot in a material stock file 19. Furthermore, the material component used for the previous confirmation is shifted from the stock under the receiving inspection.  The number of material pieces used for the previous confirmation is put into the assembling process and therefore subtracted from the total material stock.

Filed: 1989-04-19
Abstract: PURPOSE:To improve the natural frequency of an actuator and to improve driving sensitivity by magnetically coupling the both ends of a guide shaft and a fixed magnetic unit to a casing composed of a magnetic substance. CONSTITUTION:A magnet 25 for focusing, which is almost ring-shaped as a whole, is formed by using plural circular arc-shaped sintered magnets.

Abstract: PURPOSE:To uniformize temperature distribution of a whole surface, by a method wherein spaces, partitioned by partition walls and having one released and surface and the other closed end surface, and spaces having the released and closed end surfaces reversed to those of the former space are alternately aligned. CONSTITUTION:A hollow panel 1 is partitioned by partition walls 10 positioned in a dust in juxtaposition in the same direction extending from an end surface 5 to an end surface 6. The end surfaces 5 are closed with their respective partition plates 11 at intervals of one end surface. The end surfaces 6 are also closed in a similar manner, but are closed alternately with the end surface 5. Hot air or cold air is discharged in the hollow panel 1 through the end surfaces 5 and the end surfaces 6, but since the closed end surfaces 5 and 6 are displaced alternately with each other, an air duct, in which hot air or cold air is sucked through the end surface 5, and an air duct, in which it is sucked through the end surface 6, are alternately arranged. A temperature distribution difference is produced between two types of hot air passing through the air ducts having the end surfaces 5 and 6, but two types of hot air discharged through opening parts 7 are immediately mixed together, and thereby temperature distribution of surrounding air is averaged.
