Title: Blood filter and method for removing potassium ion in blood
Inventor: MOTOMURA TADAHIRO
IPC: A61M1/16
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To selectively lower only the potassium concentration without breaking electrolytic balance by using an inorganic compound having a potassium ion memory characteristic as an adsorbent and selectively removing the potassium ions in blood. SOLUTION: This blood filter uses the inorganic compound having the potassium ion memory characteristic as the adsorbent and selectively removes the potassium ions in the blood. The inorganic compound having the potassium ion memory characteristic is a compound formed by substitution of the potassium ions in a potassium-containing inorganic complex to substitutive cation, such as proton and is a cationic compound having a skeletal structure capable of capturing the potassium ions into the molecules.  More specifically, the blood filter may be obtained by introducing the potassium ions into, for example, the inorganic compound (host compound) in the state of maintaining the ion bond and forming the skeletal structure while holding the covalent bond of the host compound, then converting the potassium ions to the substitutive cation without substantially changing the skeletal structure capable of holding the potassium ions.

Title: Helicopter attitude control device
Inventor: AZUMA KENICHI
IPC: B64C27/04
Filed: 1993-04-23
Abstract: PURPOSE:To enable the use of generated longitudinal force for the longitudinal attitude control of a helicopter by allowing a tail rotor to be operated in the cant angle holding state from the horizontal direction. CONSTITUTION:A signal from an attitude angle sensor 2 detecting the attitude angle of an airframe 01 is inputted into a controller 3. A target attitude angle signal delta preset or set by the operation of a pilot is also inputted into the controller 3. On the basis of these signals, the controller 3 computes the extent the rotating face of a tail rotor 13 is to be inclined toward an axis of the airframe direction from the vertical plane in order to attain the target attitude from the vertical plane in order to attain the target attitude angle of the airframe 01. The cant angle signal of the tail rotor 13 computed by the controller 3 is sent to variable cant angle mechanism 14, and the tail rotor 13 is set to the specified cant angle. Since the tail rotor 13 becomes different force from the force generated in the longitudinal and lateral directions before setting, the dynamics of the airframe 01 changes, and this is detected by the attitude angle sensor 2 so as to obtain the target attitude angle of the airframe 01 in the end.

Title: Toothbrush
Inventor: TANAKA YUJI
IPC: A46B9/04
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a toothbrush easy to handle in the mouth, capable of effectively cleaning occlusal surfaces or interdental parts which are frequently affected by dental caries by even a baby or child unskilled in brushing operation, and hardly impairing gingiva or malar mucosa even when the tips of bristles are erroneously and strongly abutted on the gingiva or malar mucosa. SOLUTION: In this toothbrush provided with a head part 1 on which plural bundles of bristles 2 are filled on a filling surface 3, a neck part and a grip part succeeding the head part, the tip part of the bristle bundle 2 is cut into chevron shape when a brush part is viewed from the side face, and a level difference A between a mount part 2a and a valley part 2b of the chevron shape is defined as 7% to 15% of a full length B of the brush. Since the tip of the bristle bundle is cut into the chevron shape, the tips of bristles can reach even a narrow gap such as lacuna or interdental part of occlusal surface even when the length of the brush is short, then a cleaning effect is enhanced.  Also, since the level difference between the mount part and the valley part is 7% to 15% of the length of the brush, the apex of the chevron shape is not too sharp, so that the inside of the mouth is not impaired even by unskilled brushing by baby or child.

Title: Video equipment capable of canceling monochromatic image
Inventor: YOSHIDA NOBORU
IPC: H04N5/44
Filed: 1994-05-12
Abstract: PURPOSE:To cancel a blue back function only for a channel without received signal by canceling the display state of a monochromatic image with a cancel button operated during the display of the monochromatic image and thereby displaying a receiving channel. CONSTITUTION:When a horizontal synchronizing signal SH of an exact frequency is not applied from a video signal processing circuit 7 since the receiving state of a channel under receiving is faulty, a PLL tuning control part 12 judges the absence of a received signal in that receiving channel and displays the monochromatic image in blue over the full surface on a receiver 8. When a viewer operates the same tuning button 13 in such a receiving state, a comparator part 14 compares channel data shown by that operate signal with channel data stored in a channel storage part 15 and outputs a coincidence signal to the PLL tuning control part 12. Thus, the PLL tuning control part 12 outputs a control signal S1 showing blue back off to the video signal processing circuit 7, cancels blue back and displays an image just under reception at preset on the receiver 8.

Title: Delivery pressure pulsation reducing mechanism for liquid pump
Inventor: MIYAJI TATSUYA
IPC: F04B11/00
Filed: 1991-04-30
Abstract: PURPOSE:To reduce the occurrence of delivery pulsation of a liquid pump throughout a wide range of the number of revolutions. CONSTITUTION:A variable displacement swash plate type axial plunger pump 10 changes the inclination angle of a non-rotating swash plate 18 by means of a capacity control piston 17 to vary a delivery amount. In control through which a delivery amount is maintained at a constant value when the number of revolutions of a rotary shaft 14 is fluctuated, a control oil pressure having magnitude responding to the number of revolutions is fed to a hole part 13b to move the piston 17. In structure shown in a figure, displacement of the piston 17 is transferred to a spool 320 through a rod 312, and the volume of a resonance chamber 322 and the length of a communicating pipe between a delivery passage 30 and a cylindrical passage 323 are simultaneously changed. Since the resonance frequency of a resonator 300 is changed in response to the number of revolutions and thus the frequency of delivery pulsation, a resonance frequency can coincide with the frequency of pulsation in any running state, and the occurrence of delivery pressure pulsation can be reduced in a wide range of the number of revolutions.
