Title: Television signal transmitter and receiver
Inventor: SUZUKI YOSHIO
IPC: H04N5/932
Filed: 1981-12-26
Abstract: PURPOSE:To secure excellent transmission quality with limited sending power by using a high frequency signal at the top end of a video signal band or outside of said band as a horizontal synchronizing signal, and maximizing the frequency shift of a video signal within a permissible range. CONSTITUTION:A frequency demodulating circuit 31 demodulates a TV signal 20 and a band-pass filter 32 extracts a high frequency signal 21 containing the horizontal synchronizing signal from the demodulated signal. An envelope detection circuit 33 detects the envelopes of the output signal of the filter 32 to extract a horizontal synchronizing frequency component. A synchronizing pulse and gate signal generating circuit 34 generate various gate signals and horizontal  synchronizing pulses. A synchronizing pulse inserting and clamping circuit 35 replaces the horizontal synchronizing signal part in the demodulated signal passed through a delay device 36 from the demodulating circuit 31 by the horizontal synchronizing pulses from the circuit 34 on the basis of the gate signals of the circuit 34 to perform DC regeneration. The resulting signal provides a television composite signal similar to the signal for a normal TV receiver.

Title: Air conditioner
Inventor: ICHINOMIYA TOSHIKI
IPC: F24F11/02
Filed: 1988-08-30
Abstract: PURPOSE:To enable a refrigerant circuit to be kept in a pressure condition having always excellent efficiency by providing a pressure control means which receives a signal from a pressure sensor to control the number of revolutions of an outdoor fan. CONSTITUTION:A pressure sensor 6 is mounted on the delivery side of a compressor 1, and a pressure control means 7 is provided for deciding by means of a signal from the pressure sensor whether a pressure is higher or lower than a preset proper value and issuing a frequency command to an inverter 9 connected to an outdoor fan 8. LP produces the lower limit of a proper pressure and HP produces the upper limit of a proper pressure, when a delivery pressure P is in a relation of LP <= P <= HP, the pressure control means 7 judges that an air conditioner is run within a proper pressure, and a frequency command to the inverter 9 is not changed. In the case of HP < P, the pressure control means 7 outputs a command by means of which the frequency of the inverter 9 is reduced. Meanwhile, in the case of P < LP, the pressure control means 7 outputs a command by means of which the frequency of the inverter 9 is increased. Thus, a delivery pressure is kept at an always constant value through a change in the number of revolutions of the outdoor fan and a change in an amount of blast to a heat exchanger on the outdoor side.

Title: Manufacture of fine magnetic particles for fixing physiologically active material
Inventor: NAGAO HIROMASA
IPC: G01N33/543
Filed: 1993-08-31
Abstract: PURPOSE:To obtain fine magnetic particles for fixing physiologically active materials by fixing fine magnetic particles and resin particles having specific particle sizes by using an impacting method in a high speed airflow. CONSTITUTION:When the particles of a ferrite and resin are made to repeatedly collide with each other and with blades for impact fitted to a rotor rotating at a high speed by scattering the particles in an airflow of about 100m in speed generated by means of the rotor, small particles (ferrite particles, etc.) are fixed on and in large particles (resin particles), because the small particles adhere to and are buried in the large particles. When the particle size ratio between the large and small particles is set at 10:1, a uniform single coating layer of the small particles can be formed on the surface of each large particle. The fine magnetic particles obtained as a solid carrier by this method can adsorb an immunologically active material, etc. When the surfaces of the fine particles are improved and a functional group is introduced to the surfaces, the immunologically active material can be fixed by covalent bonding.

Title: Raster shift circuit
Inventor: IWAI NORIHIRO
IPC: H04N9/31
Filed: 1987-08-28
Abstract: PURPOSE:To form a high brightness screen by connecting S-shaped capacitors splittingly to each of red, blue and green horizontal yokes of a video projector using three red, blue, green projection type cathode ray tubes so as to constitute the red deflection yoke and the blue deflection yoke as closed loops and causing a DC current to flow thereto thereby relieving the load. CONSTITUTION:The S-shaped capacitor is split respectively for red, blue, green yokes so as to cause a DC current I to flow to them while the red horizontal deflection yoke 21, the blue horizontal deflection yoke 23 and a DC power supply 28 are used as a closed loop. Thus, the center of the red, blue rasters 31, 33 is moved from the center of the screen of the CRT tube toward the side reduced in the horizontal direction simply. The moving quantity is varied simply by the value of a resistor 29 inserted in series with the DC power supply 28. Moreover, the DC power supply 28 is obtained by giving a +B flowing current of a horizontal output transistor 27 to a transformer and rectifying the secondary voltage. Thus, the raster size is more increased, the load per unit area of the fluorescent screen is relieved to obtain a high brightness screen.

Title: Thermal recording paper
Inventor: MORONUKI KATSUMI
IPC: B41M5/28
Filed: 1986-09-16
Abstract: PURPOSE: To obtain the title recording paper imparting color forming density not lowered even at the time of color formation under high energy and excellent in dot reproducibility, by interposing an intermediate layer based on scaly barium sulfate having oil absorption of a predetermined value between a paper support and a thermal color forming layer. CONSTITUTION: An intermediate layer based on scaly barium sulfate having oil absorption of below 30ml/100g is interposed between a support and a thermal color forming layer. Scaly barium sulfate pref. has a diameter/thickness ratio of 4 or more and a diameter of 10mum or less. Since said intermediate layer is low in oil absorption, the excessive penetration of a color forming component in the intermediate layer at the time of color formation is prevented and, even when printing is performed using high energy, developed color density is high. Since barium sulfate is scaly, when the thermal layer is provided to an upper layer, the surface smoothness thereof is high and the close adhesiveness thereof with a thermal head is well and, as a result, dot reproducibility is improved.

Title: High quality character generator
Inventor: KUDO MAKOTO
IPC: B41J2/485
Filed: 1989-08-23
Abstract: PURPOSE:To enable a high quality dot character to be generated at high speed by using a small memory area by a method wherein a dot is reversed to a rear of each scan line with an outline system character data and at last, a dot before each scan line dot pair to a dot by one dot this side of that thereafter are coated out. CONSTITUTION:A read dot calculation part D calculates a dot of which a center is above behind a scan line to an intersecting point of the scan line and a straight or curved line and which is more near, and a dot reversion part E reverses said calculated dot by ON to OFF on a dot area. Lastly, a dot coating out part F turns each scan line on the dot area B from an odd-numbered dot being ON to a dot by one dot this side of an even-numbered dot ON, and coats out the even-numbered dot by OFF. That is, a dot of which the center is inside an outline of a character data is coated, and a dot which is outside the outline is not coated. Thereby, making a dot faithfully to the original outline character can be performed, and a high quality dot character is formed.
