Patent JP-H04158192-A (JP)
Title: Heat exchanger
Inventor: MASUKAWA SEIZOU
IPC: F28F1/40
Filed: 1990-10-23
Abstract: PURPOSE:To prevent a clogging of a gas flow passage caused by a film-like flow from being generated and make a substantial reduction of noise caused by an intermittent opening or closing of the gas flow passage by a method wherein a plurality of flow liquid grooves wider than that of heat transferring groove are formed in a spaced-apart relation in a circumferential direction at an inner surface of each of curved lines in a heat exchanger having bent connection pipes. CONSTITUTION:Cylinders 18 are formed at both ends of a connection pipe 16. Each of linear line portions 10A of a heat transferring pipe 10 is inserted into these cylinders 18 and fixed there. Since a plurality of flow liquid grooves 14 having wider width than that of a helical groove 12 and extending along an axial direction are formed within a curved line part 10B of a heat transferring pipe 10, refrigerant flows along each of the flow liquid grooves 14 having wider width and thus a uniform film-like flow clogging the inside part of the curved line 10B is not formed. A width of each of the flow liquid grooves 14 is wider than that of the helical groove 12 and preferably about 3 to 30% of an inner diameter of the heat transferring pipe 10. A depth of each of the flow liquid grooves 14 is the same or slightly deeper than that of the helical groove 12 and the bottom surface of each of the flow liquid grooves 14 is made flat and smooth. When the film-like flow or the gas flow is intermittently broken, the noise generated during this operation can be substantially reduced.

Title: Chirp signal generator
Inventor: FUTAGAWA NORIO
IPC: G01S13/28
Filed: 1988-11-10
Abstract: PURPOSE:To enable measurement of a distance to a target located at a very long distance and to settle the problem of ambiguity by modulating a chirp signal in phase by a predetermined digital signal. CONSTITUTION:In a reception system, a received chirp signal (d) reflected by a target 3 and received by a reception antenna 4 is time-compressed by a pulse compressor 5. A time difference detector 6 detects a time difference between a pulse signal (e) time-compressed thereby and a timing signal (a). The phase of the time-compressed pulse signal (e) is detected by a phase demodulator 8 and the phase demodulated signal (f) is outputted therefrom. A distance converter 7 can determine an equivalent distance to the target 3 from an output of the time difference detector 6 and the phase demodulated signal (f). Since a transmitted chirp signal (c) is phase-modulated by a predetermined digital signal (b) in synchronization with the timing signal (a) in this way, the chirp signal in each period can be discriminated by phase-modulating the received chirp signal (d).
