Patent JP-S5684007-A (JP)
Title: Amplifying circuit
Inventor: KANAI TAKASHI
IPC: H03F3/30
Filed: 1979-12-12
Abstract: PURPOSE:To prevent the generation of switching distortion by increasing the bias of one transistor of a class ''B'' SEPP amplifier according to an increase in load current of the SEPP amplifier. CONSTITUTION:When current i5 flowing through load ZL is greater than zero and emitter currents i3 and i4 of transistors Q8 and Q10 are also greater than idling current, voltage Va is large when i5=0, and consequently current IC3 increases, so that the gain of differential amplifier DK1 will be increased. Consequently, negative feedback is provided between terminals t2 and t3 and the voltage between t2 and t3 is almost unchanged. At this time, transistor Q10 never turns off through the operation of diode D2 and transistor Q2. When i5<0, transistor Q8 will not turn off neither.

Title: Blood vessel photographing method by mri and mr angiograph
Inventor: HATTA JUNICHI
IPC: A61B5/055
Filed: 1993-06-30
Abstract: PURPOSE:To enable the understanding of the structure of a blood vessel in a slice area three-dimensionally by performing a photographing in each polarity once and twice in total while inverting the polarity of a flow encode pulse to subtract a data thereof two-dimensionally. CONSTITUTION:One polarity of a bipolar gradient pulse (flow encode pulse 9 (c)) is used to apply a phase shift proportional to the velocity of a blood stream only to a blood stream signal in a slice area while a unipolar gradient pulse (depth encode pulse (e)) in the direction of slicing is used to apply the phase shift proportional to the position in the direction of slicing in the slice area thereby collecting a nuclear magnetic resonance signal. Thereafter, the polarity alone of the bipolar gradient pulse is inverted to collect the nuclear magnetic resonance signal likewise. Image data of first and second projection images in the direction of slicing in the slice area based on the signal collected are computed based on the signal collected and the image data are subtracted mutually to obtain a projection image of a blood vessel. This method enables the obtaining of the projection image of the blood vessel fed with depth information in the direction of slicing.

Title: Multioutput switching regulator
Inventor: INAO KIYOHARU
IPC: H02M3/28
Filed: 1995-06-29
Abstract: PURPOSE: To stabilize the output voltage control by employing the side having relatively high output voltage as a suboutput circuit for driving a photocoupler and forming an AG feedback circuit comprising an error amplifier thereby improving the phase margin of control loop. CONSTITUTION: The output power from a main output circuit, i.e., the product of main output voltage Vout1 and load current I1 , is set lower than the output power from a suboutput circuit, i.e., the product of suboutput voltage Vout2 and a load current I2 . The DC component is stabilized through negative feedback employing an error amplifier 10 and a PWM control circuit 20 where a signal, obtained by dividing the main output voltage Vout1 , is delivered to the reference terminal of error amplifier 10. The Ac component is stabilized by connecting the cathode terminal of error amplifier 10 with the output voltage Vout2 through a diode D3 in a photocoupler PC. This circuitry improves the phase margin of control loop by lowering the gain for the variation of output and enhances stability of control by suppressing the oscillation.

Title: Positive photosensitive composition, photosensitive planographic printing plate and positive image forming method
Inventor: URANO TOSHIYOSHI
IPC: C09D201/00
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To ensure high sensitivity to near infrared laser, wide development latitude and no coating defects by incorporating a coloring material having an N,N-diaryliminium salt skeleton in its molecule. SOLUTION: A coloring material having at least one N,N-diarylirninium salt skeleton or N,N-diarylaminium skeleton in its molecule is incorporated as a near infrared light-heat conversion material. The coloring material absorbs light in the 650-1,300 nm wavelength range of a light source for exposure and generates heat. The near infrared light-heat conversion material has a high dissolution inhibiting effect by which solubility to an alkali developer is reduced by forming a hydrogen bond matrix by way of active hydrogen of hydroxyl groups or the like of an alkali-soluble resin.  When the near infrared light-heat conversion material is irradiated with near infrared laser, it loses the high dissolution inhibiting effect because hydrogen bonds are relaxed or dissociated by the action of heat generated by the near infrared light-heat conversion material in the exposed part to facilitate the penetration of the alkali developer into a photosensitive layer.
