Title: Power amplifier
Inventor: TAKUMA HIROSHI
IPC: H03F1/02
Filed: 1990-11-02
Abstract: PURPOSE:To increase a collector loss of a transistor(TR) by switching a voltage fed to a power amplifier from a low voltage to a high voltage before an input signal is clipped even at reduction in a power supply voltage. CONSTITUTION:An input voice signal is subject to current amplification by a transistor(TR) 12, its output audio signal is fed to a speaker 13, from which a voice is outputted. Since a voltage of a low level input voice signal fed to a base via a diode D1a is low, TRs 18a, 19a are nonconductive. When the voltage of the input voice signal is gradually increased and a base voltage of the TR 18a gets higher via the diode D1a, the TR 18a is conductive. Succeedingly, the TR 19a is conductive succeedingly and a voltage of a high voltage power supply 16a is fed to a TR 12a and a high output amplifier signal is fed to a speaker 3. Thus, even when the power supply voltage is low, normal operation is kept and the power supply is effectively used.

Title: Wavelength stabilizing control system
Inventor: FURUYAMA YOSHITO
IPC: H01S3/13
Filed: 1993-11-29
Abstract: PURPOSE:To allow offset locking of the frequency of laser light while stabilizing. CONSTITUTION:A laser light emitting means 1 emits a laser light and laser light modulating means 2 receives the laser light and outputs modulated and unmodulated laser lights. A resonance signal output means 3 absorbs the modulated and unmodulated lights from the laser modulating means 2 according to the absorption characteristics and delivers two types of resonance signal corresponding to the modulated and unmodulated lights. A wavelength control signal output means 4 detects the two types of resonance signal synchronously and feeds a wavelength control signal, obtained depending on the difference of potential between the two types of resonance signals, back to the laser light emitting means 1 thus controlling the wavelength of laser light stably. Since the laser light emitting means 1 is controlled only by the driving current from a current source, unmodulated laser light having stabilized frequency is emitted from the laser light emitting means 1.

Title: Scintillation camera
Inventor: TANAKA MASATOSHI
IPC: G01T1/164
Filed: 1994-11-08
Abstract: PURPOSE: To prepare appropriate uniformity distortion correcting data by correcting a distribution image in accordance with the difference in magnitude of the solid angle against a point radiation source at each position within the visual field of a detector before the correcting data are prepared. CONSTITUTION: Uncorrected data are collected by providing a point radiation source container 11 containing a radioactive isotope at a distance D from the center C of the visual field of a detector 1 on a vertical line passing through the center C. Firstly, the nonuniformity of incident γ-rays which is caused by the difference in solid angle against the container 11 is removed by dividing the data by a solid angle ratio K (x, y). The ratio K (x, y) at each position (x, y) measured from the center C becomes K (x, y)=D<3> /(D<2> +x<2> +y<2> )<3/2> . Then the average value of the corrected data in the entire visual field of the detector 1 is found and a table is prepared by using the correcting amount at each position and stored on a magnetic disk.  At the time of collecting actual data, the detected data of the detector 1 are corrected by using the correcting amount at each position read out from the table. Therefore, appropriate uniformity distortion correcting data can be obtained.

Title: Sound source-characteristic extracting method
Inventor: SHIRAKI YUICHI
IPC: G01S3/802
Filed: 1991-11-14
Abstract: PURPOSE:To provide the initial-value setting processing, which is resistant to frequency noises. CONSTITUTION:The amounts of the characteristics such as the bearings and the frequency of a sound source are regarded as the parameters of the specified nonlinear combination functions. The error between a received signal (a) and an estimated signal is repeatedly evaluated. Thus the amounts of the characteristics are extracted. With regard to a processing 1 for setting the initial value in this method, a broad-band beam is formed by Fourier transformation and inverse Fourier transformation in a bearings analyzing part 11. The phasing signals for a plurality of the predetermined bearings are formed. The initial value of the bearings is set based on the maximum value of the power spectrums of the phasing signals. The initial value of the time characteristic amount is set based on the phase signal, which is phase with the initial value of the bearings. Since the direction of the larger sound is regarded as the bearings of the sound source, the initial value, which is resistant to frequence noises, can be set.
