IPC: G01T1/164
Filed: 1987-09-30
Abstract: PURPOSE:To collect the data with high accuracy by correcting a reference value of a period which is measured first based on a fluctuation, of the fluctuation can be regarded as a normal fluctuation, even in case when a period of a pulsation, etc., is fluctuated. CONSTITUTION:Before executing an accumulation of a signal from a gamma camera 1, an R-wave signal from an electrocardiograph 6 is inputted to a CPU 5, a data of an R-R interval T is collected, and a frequency distribution is obtained. Subsequently, from this frequency distribution, a standard value, the maximum value and the minimum value of the period T are derived, they are sent to an R-R interval deciding and setting circuit 8, and the maximum value and the minimum value of the period T are set. Thereafter, the signal from the camera 1 is inputted to a buffer memory 3, and whether the interval T of that time is contained in the maximum value and the minimum value or not is decided by the circuit 8. When it is decided to be contained, the data which is accumulated in the memory 3 is transferred to a collecting memory 4, and when it is decided not to be contained, the data of that time is rejected. Accordingly, the circuit 8 decides whether the interval T is contained within a range which is corrected at every period or not, and the data can be collected with high accuracy.

Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To obtain a desired heat exchange performance even if R410-based refrigerant is used in place of R22-based refrigerant, in a refrigeration cycle in which R410-based pseudo-azeotropic mixture refrigerant is used, by providing a tank for changing circulation composition ratio of refrigerant midway between an outdoor heat exchanger and indoor heat exchanger. SOLUTION: In a refrigeration cycle of an air conditioner, a tank 11 and tank 12 are respectively connected to heat exchanger tubes 8 of an indoor heat exchanger 5 and outdoor heat exchanger 3, and a predetermined amount of R410 A-based pseudo-azeotropic mixture refrigerant comprising R32 and R125-based refrigerants is sealed in the tanks 11, 12. At the time of a cooling operation, refrigerant delivered from a compressor 1 returns again to the compressor 1 via a four-way valve 2, the exchanger 3, pressure reducing means 4, the exchanger 5, and the valve 2; however since R125 refrigerant is condensed more easily than R32 refrigerant, R125 refrigerant is stored in the tank 11 and hence the ratio of R32 refrigerant which circulates increases. Thus amounts of heat exchange equivalent to the amount of refrigerant in the case that R22 refrigerant of single component is used can be obtained.

Title: Power supply for silent discharge
Inventor: TAKECHI KAZUHIRO
IPC: H02M7/48
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To lower a switching loss when voltage rises, by providing a switching element controlling power supply to the primary side of a transformer and a gate pulse control means supplying a pulse to a gate of the switching element in synchronization with oscillation voltage of the secondary side of the transformer. SOLUTION: If a gate pulse generating circuit is constituted so that it generates a pulse only when a zero-cross signal arrives, an additional tuning circuit is not necessary, because the gate pulse generating circuit itself has a synchronization function. Thus, the current flowing in a switching element 13 becomes a sine wave after the gate pulse is impressed, by adding the gate pulse in synchronization with the rise of oscillation voltage. Consequently, the current at the voltage rise of the switching element 13 is zero, then, a switching element loss, that is, a power loss in the switching element is lowered.
