Title: Hot gas engine
Inventor: HARADA TERUMARU
IPC: F02G1/053
Filed: 1980-06-26
Abstract: PURPOSE:To prevent a motive power loss, by connecting the opening between a piston and a partition plate, which is provided in a low-temperature opening, to that between a displacer and the partition plate through a unit including an oil filter, to keep constant the pressure of the openings on both the sides of the partition plate. CONSTITUTION:A low-temperature opening 12 defined by a flexible partition plate 11 and a piston 3 and another low-temperature opening 6 defined by the partition plate 11 and a displacer 2 are connected to each other through a unit 14 including an oil filter 13. The oil filler 13 prevents oil from being conducted to a high-temperature opening. The pressure of the low-temperature openings 6, 12 is kept constant. For that reason, no unnecessary force acts to the partition plate 11. Therefore, the lifetime of the plate 11 is lengthened. Since fluctuating pressure is well transmitted between the openings 6, 12, a motive power loss is low.

Title: Method for searching for route
Inventor: ICHIMURA ATSUSHI
IPC: G01C21/00
Filed: 1994-03-31
Abstract: PURPOSE:To correctly set a search start point or a search end point in conformity with a user's desire when a route to a destination or a passing midway point is to be searched in a navigation apparatus which updates and displays a current position of a vehicle on a map screen as the vehicle runs. CONSTITUTION:A link L5 nearest to a point P0 designated by a user is selected, and sequentially traced to extract a node N3 of an intersection. If the node N3 is within a distance (r) from a point P1 which is a projected point of true point P0 on the link L5, the node N3 is set as a search point. If the node is not within the distance (r), one of the nodes N4 and N5 at both ends which is nearer to the node N3 and within the distance (r) is selected. If the nodes N4 and N5 are not present in the distance (r), a pseudo node is formed. In this manner, even when a distance between nodes is long, for example, in arm expressway, it is possible to search to a point proximate to the point P0 without a sense of incompatibility.

Title: Method for welding metallic building material in place of screwing method
Inventor: NAGAO SHUNSUI
IPC: B23K37/04
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent the twisting or squeaking, to guarantee the correct work, and to save the labor by providing a groove in a side surface of a rod-like metallic building material, and achieving the insertion welding of a clawed building material thereto. SOLUTION: A joining method is to provide a groove 2 in a rod-like metallic building material 1, and insert a building material 4 having a claw 3 therein for welding. Deterioration of the strength due to a hole can be prevented, and the strength of a structural body itself can be increased because no twisting is generated. Further, disposal of the material due to mistakenly opened holes can be prevented. This joining method can be applied not only to the core material joining mainly used for a flush door such as a general door each side of which is laminated with a decorative sheet, but also to larger structures. Because the method is based on the covering by the decorative sheet, a process to grind the pollution due to the welding can be dispensed with.
