Title: Ink drop arranging method and ink jet printer
Inventor: LEAN MENG H
IPC: B65H5/00
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To provide an on demand ink jet printer in which the movement accuracy of a recording medium relative to the print head of a printer and the ink drop arranging accuracy on the recording medium are enhanced. SOLUTION: A carrying belt is charged electrostatically with charges 46 of one polarity. A recording medium 24 is fed on the carrying belt and held precisely at a positioning position on the carrying belt. Charges of opposite polarity are induced in an ink drop 38 jetted from a print head 16 to generate an electrostatic voltage for accelerating the ink drop 38 toward the recording medium 24. Since the ink drop 38 is accelerated, the effect of transverse force due to a transverse air flow, or the like, on the directivity of the ink drop 38 is reduced. Furthermore, the arranging error of the ink drop 38 caused by an already printed image repelling the arriving ink drop 38 is reduced because the charges of a printed ink drop 38 are passed through the recording medium 24 and canceled.

Title: Clouding of polyester resin molding
Inventor: OGIWARA YOUICHI
IPC: C08J7/02
Filed: 1979-12-28
Abstract: PURPOSE: To cloud a polyester resin molding, by applying a solvent which dissolves or swells a saturated polyester resin, on the surface of the molding and then volatilizing the solvent.  
     CONSTITUTION: A solvent which dissolves or swells a polyester resin, such as an ester type solvent such as ethyl acetate, is applied on the surface of a molding of a saturated polyester resin such as polyethylene terephthalate. Then, the molding is left to volatilize the solvent applied. By this, the applied area of the molding is clouded. Methods of applying the solvent include immersion of the molding in a solvent for an appropriate time or coating the molding with a solvent by use of a roller coater. The above treatment not only achieves clouding but also improves the heat resistance and strength of a molding. If the improvement in these properties is intended, it is preferred to conduct the solvent treatment so that the crystallinity of the polyester resin on the surface of the molding to which a solvent has been applied is at least 6%.

Title: Round-shaped type high-speed boat
Inventor: KIHARA KAZUYUKI
IPC: B63B1/18
Filed: 1984-08-13
Abstract: PURPOSE:To uplift a stern part as well as to make a boat easily shiftable to its gliding state, by forming a skeg in a stern bottom part of a round type cross sectional ship, while making up a bracket of a propeller shaft projected out of the skeg into a posture or a form generating the force of upward lift in time of sailing at high speed. CONSTITUTION:In case of a high-speed boat having a round-shaped bulged cross section toward the bottom center from both ship sides, a skeg 5 is installed in the bottom part, and a propeller shaft 6 is supported by a bracket 1 projectingly installed in a ship lateral direction from the side of the skeg 5. The bracket 1 is set up in a posture having an upperward tilt frontward so as to generate the force of upward lift in time of sailing at high speed. According to this method, owing to being a round-shaped ship type, not only an impact in time of rolling and pitching in the ship is reduced but also the stern part is lifted up by dint of the upward lift by the bracket and shifting to a gliding state can be done in an easy manner.

Filed: 1992-06-29
Abstract: PURPOSE: To automatically and accurately decide the evaluation based on the lean meat/fat content of alive animal or slaughtered body by moving an ultrasonic unit, measuring, storing and analyzing a reflection signal at a plurality of positions. CONSTITUTION: A fixing unit 20 is disposed so that an alive animal or slaughtered body (specimen) is near an ultrasonic transducer 36.

Filed: 1990-06-26
Abstract: PURPOSE:To reduce a memory cell by providing a clamp circuit to hold respective bit line potentials and respective input/output line potentials lower than a prescribed potential and constituting the gate length of a transistor constituting the static memory cell shorter than the gate length of the other peripheral transistor. CONSTITUTION:A clamp circuit 50 is provided to clamp the bit line potential and the input/output line potential. Since the output voltage of the clamp circuit 50 is held at a prescribed value when a power supply voltage Vcc increases beyond a fixed value, the gate voltages of bit line load transistors 25a and 25b are held at a prescribed value and conductive resistance is not lowered even when the power supply voltage Vcc increases. Therefore, any high voltage is not impressed through the bit line load transistors 25a and 25b to access transistors 42a and 42b and driver transistors 41a and 41b. Accordingly, any transistors having low pressure resistance, namely, short gate length can be used for the access transistors 42a and 42b and the driver transistors 41a and 41b. Thus, the memory cell can be reduced.
