Patent JP-S61131906-A (JP)
Title: Power amplifier
Inventor: NIWA FUMIYUKI
IPC: H03F3/68
Filed: 1984-11-30
Abstract: PURPOSE:To realize a low distortion factor and to decrease a DC voltage difference between outputs by placing a non-inverting negative feedback amplifier circuit to the 1st stage and inverting the phase by an inverting negative feedback amplifier circuit so as to decrease the variance in the voltage gain. CONSTITUTION:When a signal is inputted to an input terminal 115, a non-inverting negative feedback amplifier circuit 101 having a gain 0dB inputs a signal having the same amplitude and in phase with the input signal to a negative feedback circuit 103, from which a signal amplified by a factor of the gain is outputted to an output terminal 117. On the other hand, a signal inputted to an inverting negative feedback amplifier circuit 102 with gain 0dB via the circuit 101 becomes an inverted signal with the same amplitude as the input signal, amplified by a negative feedback circuit 104 and outputted to an output terminal 118. In this case, the gain of the circuits 101, 102 is the unity, the feedback rate is the unity and the voltage gain variation and distortion factor of each amplifier circuit are decreased to 1/(1+Avo) with respect to those at no feedback and then the circuit is stabilized, where Avo is the voltage gain. Further, the voltage gain variance is compressed to stabilize the DC voltage difference between output terminals thereby realizing a low distortion factor.

Title: Balloon pump for inside of aorta
Inventor: KANAI SHIGETOMO
IPC: A61M25/08
Filed: 1989-09-30
Abstract: PURPOSE:To insert a balloon to the aorta of a patient safely even by a non- skillful person by providing a means on a catheter member side or a sheath member side to detect that the rear end of the balloon and the front end of the sheath member are separated by more than a prescribed distance. CONSTITUTION:In a center tube 12, a blue detection color area 40 is formed as the detecting means. A balloon 13 is inserted through a sheath 29 to a descending aorta 2 and it is detected, however, that the rear end part of the balloon 13 is not sufficiently separated from a blade-shaped part 29a of the sheath 29. In such a position, the balloon is not returned back for adjusting the insertion but advanced to be inserted as it is. When the balloon 13 is further deeply inserted to the aorta 2, the rear end part of the balloon 13 is sufficiently separated from the blade-shaped part 29a of the sheath 29. In such a state, the detection color area 40 is already hidden in the sheath 29 and not detected from an external part. Thus, even when an operator returns the balloon 13 back for adjusting the insertion after the state that the detection color area 40 is not detected from the external part, the balloon 13 is prevented from being damaged by engagement with the blade-shaped part 29a of the sheath 29.

Title: Beam width converter of surface acoustic wave
Inventor: NAKAMURA KENJI
IPC: G02F1/335
Filed: 1984-12-03
Abstract: PURPOSE:To convert a beam width while holding the uniformity of power distribution of a surface acoustic wave after beam width conversion by varying the film thickness of the surface acoustic wave guide thin film of a beam width converter in the direction orthogonal to the propagation direction of the surface acoustic wave. CONSTITUTION:An incident surface acoustic wave 1 is made incident on the incidence end A-A' of a surface acoustic wave beam width converter 5 and is propagated in a dielectric thin film of the converter 5 and is discharged from an exit end E-E' as an exit surface acoustic wave 2. Since the dielectric thin film of the beam width converter 5 has a film thickness distribution in the direction orthogonal to the propagation direction of the surface acoustic wave, the propagation direction of the surface acoustic wave propagated in the converter 5 is deflected to the direction of the thicker film. This film thick ness distribution is set to a desired shape, and thereby, the surface acoustic wave has a uniform power distribution after it is radiated from the exit end E-E' to become the exit surface acoustic wave 2 having a beam width LB.

Filed: 1988-10-08
Abstract: PURPOSE: To minimize the sensitivity of a system to the interference signal from a signal source and to synchronize a detector with a driving signal for correct demodulation by including a controllable light source and a photodetector means which forms an electric signal in response with the receipt of the light from this light source. CONSTITUTION: LEDs of two wavelengths are used in order to collect the signal components used to calculate pulse oxygen saturation with a pulse oxygen meter. A photodiode 60 forms AC signals in response with the light pulses formed by these LEDs 62 and 64. The composite AC signals are applied to the primary side of two transfomers. A secondary tuning circuit responds only to the frequency component corresponding to respective resonance frequencies. The signal components amplified by an amplifier 76 and an amplifier 78 are demodulated by amplitude demodulators 100 and 102 in order to restore physiological information. The demodulated information signals, RED and IR are thereafter further filtered, by which the mixed signals are removed, and are transmitted to an oxygen meter processor for the calculation of the level of blood oxygenation.
