Title: Mode s secondary surveillance radar device
Inventor: INOUE KIICHIRO
IPC: G01S13/76
Filed: 1995-04-07
Abstract: PURPOSE: To increase data link communication capacity, relating to a secondary surveillance radar device (SSR mode S) having a mechanical rotation type antenna. CONSTITUTION: The transmission data from a inquiry management calculator 1 is converted into high-frequency signal by a transmitter 2 and transmitted from a mechanical rotation type antenna 3 having main beam and sub-beam toward an aircraft. The position of the aircraft is predicted in advance by the inquiry management calculator 1, and, usually transmission is performed at the timing when a target aircraft is present within the main beam of the mechanical rotation type antenna 3, however, when communication is not finished in the main beam and further the inquiry management calculator 1 decides that switching over to sub-beam will increase data link communication capacity, a selector switch 4 switches the output of the transmitter from the main beam over to the sub-beam, based on the switching signal from the inquiry management calculator 1.  The response signal from the aircraft is, after received by the then beam at the mechanical rotation type antenna, inputted in the receiver 5 for amplifying, and then converted into digital data by a signal processing device 6, and then inputted into the inquiry management calculator 1.

Title: Manufacture of wax pattern
Inventor: NISHIDA MASAKATSU
IPC: B22C9/04
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To improve the lowering of yield caused by the breakage of a core by manufacturing a wax shell having the outer surface outline of a desired cast product while beforehand dividing into two or more pieces, combining these divided wax shells and a core and arranging a hollow part between the wax shell and the core. SOLUTION: The wax shells 8a, 8b are the one forming a part of the outline part corresponding to the outer surface of the product as the shell-state by using a metallic mold and pouring the wax into the metallic mold with the conventional injection method. These wax shells 8a, 8b and the core are combined to make the wax pattern. Since the core is not inserted with the wax, the brittle part in the core does not break with the pouring pressure. Further, the core is not broken with stress at the time of solidifying the wax. Furthermore, since the flow-out of the wax material is very little at the time of dewaxing, the frequency of the breakage at the brittle part of the core caused by the flow-out stress becomes very small.
