Abstract: PURPOSE:To give an antithrombus character, and in the same time, enable to make the bore of an artificial blood vessel fine by coating at least the surface in contact with blood of a porous base material with a fluororesin to form an artificial patch material. CONSTITUTION:A fluororesin film is formed by the conventional method of dipping, spraying, coating, etc., with emulsion or organic solvent solution of fluororesin on at least the surface, in contact with blood of a base material, having porosity of a porous polyester or a porous polyurethane and the like. An artificial patch material is obtained by drying a pipe-shaped structure, in which the fluororesin film is formed, for about 1 to 30min at about 60 to 190 deg.C temperature. Further, concurrent use of a cross-linking agent or the like for firmly providing binding force between fluororesin and the base material and for improving durability is also effective for the emulsion or organic solvent solution of the fluororesin.

Title: Current switching type logical circuit
Inventor: SATOU FUMIHIKO
IPC: H03K19/086
Filed: 1983-05-10
Abstract: PURPOSE:To prevent a reverse current from flowing even if a low voltage is applied to an input by adding a diode between emitters of a differential transistor (TR) so as to increase the dielectric strength when viewed from the input terminal of an input transistor. CONSTITUTION:A TRQ1 to the base of which an input signal VIN is inputted is connected to a common constant current source I1 via a diode D1 and a TRQ2 to the base of which a reference voltage Vref is given is connected to the I1 via a diode D2. When the input signal VIN is not given, the base potential of the TRQ1 approaches almost a minimum potential VEE of the circuit because of a pull-down resistor R3. The effect is ensured remarkably without deteriorating the performance of the circuit in using TRs having a low reverse dielectric strength of emitter-base in this way and the leakage current is eliminated, thereby improving the reliability.

Title: Tone ringer circuit for telephone
Inventor: NISHIMURA SHINJI
IPC: H04M19/04
Filed: 1982-05-14
Abstract: PURPOSE:To obtain large sound volume with a simple circuit, by constructing a tone ringer circuit for a telephone with a self-oscillation circuit which is made of an output transformerless amplifier and a 3-terminal piezoelectric sounder. CONSTITUTION:A call signal passes a capacitor C1 for DC prevention and is rectified both waves by diodes D1-D4. Power source voltage caused by the rectified call signal between power source terminals V- and V+ of a push-pull amplifier A of complementary symmetric type is divided its voltage by resistance elements R4-R7 to be supplied to the bases of transistors (TR) Q1 and Q2. If the voltage exceeds the sum of ON-state voltage of Q1 and Q2, current flows in TRs Q1 and Q2. Due to the current, voltage is impressed between main electrodes P1 and P2 of a 3-terminal piezoelectric sounder S2. Only the resonance frequency component of the sounder S2 returns to a terminal V1 of the amplifier A via a feedback electrode P3, and self-oscillation starts at the resonance frequency of the sounder S2. Since the amount of the feedback is large, and TRs Q1 and Q2 performs switching operation, the sounder S2 obtain a large ringing sound.

Filed: 1990-03-29
Abstract: PURPOSE:To ensure synchronization by dividing a modulation signal into I and Q components with a different phase, integrating them separately, obtaining a bit timing error and correcting the deviation of bit timing so as to make the error zero. CONSTITUTION:A PCM-PSK modulation signal is inputted to the circuit, shifted by a 90 deg. phase shifter 2 in both polarities by using a signal generated from a local oscillator 1 to obtain I and Q components whose phases differ by 180 deg.. Then the l and Q components are given to adders 9/11, digitized by A/D converters 7/8 respectively and the I and Q components are integrated for a bit timing period in a prescribed timing. Then a phase angle thetak of a modulation carrier obtained based on the sum output of the I and Q components is obtained by a tan computing element 17 to detect the presence of deviation of the bit timing. Moreover, a computing element 20 corrects the deviation of the bit timing so that the bit timing error obtained based on the phase angle thetak and the timing error of the I and Q components are made zero thereby securing the synchronization of the bit timing. Thus, the synchronization of the modulation carrier is not required and the synchronization is secured.

Abstract: PURPOSE:To demodulate a transmission-side input signal train regardless of frequency variation of a local oscillator of a transmitter or a receiver, by allowing a discriminating circuit to discriminate whether the output signal train of a subtracter is higher than a specific level or not, and performing the demodulation. CONSTITUTION:A transmitter 11 delays an exclusive OR output by N bits of the input signal train through delay circuit 15 to supply the delay signal to its reception side 18, which sends out a carrier to a transmission line 17 after frequency shift (FSK) modulation. At this reception side 18, a detection output is divided into two by a hybrid 21; and one is inputted directly to the substracter and the other is inputted through an N-bit delay circuit 22 so that the both have equal amplitude. The output signal of the subtracter 23 has three amplitude values and is converted into a binary signal by an absolute value circuit 24. The FSK signal on the transmission line 17 is discriminated on the basis of only frequency difference between N-bit components, so characteristic deterioration due to variation in the center frequency of the FSK signal never occur in the linear area of the frequency-voltage characteristics of a frequency discriminator 19.
