Title: Gas liquid separation type vertical thermo siphon
Inventor: SHIRAISHI MASAO
IPC: F28D15/02
Filed: 1986-07-21
Abstract: PURPOSE:To provide a superior work efficiency and a superior thermal transportation amount by a method wherein an inner pipe having an opened upper end and having several air holes at its circumferential wall is concentrically inserted and arranged within an external pipe having a closed structure and a helical line is held between both pipes. CONSTITUTION:A heat Q is applied to an evaporater part 15 from an external source and the heat Q is retrieved from a radiation part 14, a working fluid 19 is evaporated and gasified at an evaporation part and its steam flows upwardly toward a radiation part 14 having a low pressure. In this case, the working fluid vapor is generated between the inner pipe 11 and the outer pipe 10 to generate an ascending flow. Since a helical line 12 is held between the pipes, a flowing resistance is high, resulting in that the working fluid vapor passes through air holes 17 formed in the inner pipe 11, enters the inner pie 11 and then flows toward the radiation part 14. In this way, the condensed and liquefied liquid phase working fluid in contact with an inner circumferential surface of the outer pipe 10 at the radiation part 14 flows down along the inner surface of the outer pipe 10, enters a space between the inner pipe 11 and the outer pipe 10, the working liquid becomes a helical flow due to a presence of the helical line 12 and flows out of the inner pipe 11. Therefore, the interior of the inner pipe 11 becomes a vapor passage and the outer part becomes a working fluid passage and thus a gas liquid separation is carried out.

Title: Psk demodulation circuit
Inventor: YAMAMURA HIDEYA
IPC: H04L27/227
Filed: 1990-07-02
Abstract: PURPOSE:To capture synchronism in a short time faster than ever by adding or subtracting the output signal of a filter on or from a designated phase correction signal when step out occurs. CONSTITUTION:When the amount of phase shift is increased due to the influence of a noise, etc., and for example, the output signal of the filter exceeds an upper limit value, an arithmetic circuit 4 outputs a signal in which a phase correction signal is subtracted from the output signal of the filter to an oscillator 5 as a control signal. Meanwhile, when the output signal of the filter becomes less than an addition/subtraction value within a synchronism holding range, the arithmetic circuit 4 outputs a signal in which the phase correction signal is added on the output signal of the filter to the oscillator 5 as the control signal. Thereby, since the frequency and the phase of an internal oscillation signal can be controlled in a direction to reduce phase difference at that time, the synchronism can be captured in a short time.
