Title: Device and method for synchronous acquisition of spreaded spectrum signal
Inventor: AOYAMA AKIO
IPC: H04B1/7073
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a synchronous acquisition method for preventing the detection of a pseudo-synchronous point in a correlative value sequence and for correctly detecting the synchronous points of plural incoming waves by means of a mutli-path. SOLUTION: The self correlative function of a spreading code to be used is generated before the synchronous point is detected (S1). The correlative value component of the pseudo-synchronous point belonging to the previously detected synchronous points is calculated for the detection of the n-th (n is an integer of >=2) synchronous point (S9). After the correlative value component of the pseudo-synchronous point is removed from the correlative value sequence (S10), a processing for detecting a peak point from the correlative value sequence is executed. Therefore, the n-th synchronous point is detected for the correlative value group where the correlative value component of the pseudo- synchronous point is previously removed so that it is prevented that the pseudo- synchronous point is errorneously detected.

Title: Worm type compressor
Inventor: INAGAKI MITSUO
IPC: F04C18/14
Filed: 1979-12-12
Abstract: PURPOSE: To enable to keep high cooling performance, by providing a check valve on the downstream side of a gas sealing chamber of a worm type compressor that is used in an air conditioning system, so as to prevent backflow of coolant when reverse rotation of the compressor is caused.  
     CONSTITUTION: When operation of a compressor is stopped and the pressure difference on the opposite sides of a connecting port 23 becomes zero, a check valve 24 is closed immediately by the force of a spring 28, so that high pressure coolant in an oil separating chamber 30 does not flow back into a discharge chamber 15 if pressure in the discharge chamber 15 is lowered. Therefore, reverse rotation of the compressor is not caused. Here, if reverse rotation of a rotor 3 is caused, cooling performance drops rapidly by the temperature rise of an evaporator. However, the check valve 24 is set into operation when operation of the compressor is stopped, so as to prevent backflow of coolant positively. Therefore, it is enabled to prevent occurrence of problems such as rapid temperature rise of the evaporator and thus to keep the cooling performance of the evaporator always high.
