Patent JP-H07264881-A (JP)
Title: Ultrasonic motor
Inventor: KUNIMATSU SHUJI
IPC: H02N2/00
Filed: 1994-03-23
Abstract: PURPOSE:To further improve the driving force and durability of an ultrasonic motor by coating the frictionally contacting part of the motor where a moving body comes into contact with a fixed body with a composite metallic film containing a fluororesin. CONSTITUTION:The frictionally contacting part of an ultrasonic motor is coated with a composite metallic film containing a fluororesin. While it is preferable to coat both a fixed body and moving body with the film, it is sufficiently practical even when either one of the bodies is coated with the film. The fluororesin can be polytetrafluoroethylen, perfluoroalkylester tetrafluoride, ethylene tetrafluoride-propylene hexafluoride coplymer, etc., and the metal can be aluminum, an aluminum alloy, nickel, a nickel alloy, etc. The metallic film can be formed by Tuframe process or 'clean-S' process (registered trademarks of Kinzoku Hyoumen Kagaku Co., Ltd., and Showa Denko K. K., respectively). Therefore, an ultrasonic motor which has a strong driving force and long service life and is high in durability can be obtained.

Title: Method for keeping permethrin in washable textile material and keeping means
Inventor: SAMSON RICHARD D
IPC: D06M15/263
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To obtain a textile material having mothproofing effect with excellent washing fastness by keeping permethrin in a textile material using a polyvinyl acetate. SOLUTION: A textile material such as a plain fabric of a 50/50 polyester/ cotton blend is passed through a padding bath containing 2-10 oz of polyvinyl acetate based on 1 gallon of the bath and the applied polyvinyl acetate is cured. The treated textile material is passed through a dispersion bath of permethrin which is a synthetic pyrethroid having repelling and exterminating activity to insects and the permethrin is fixed at an initial concentration of <=1.25g per 1m<2> of the textile material. As an alternative, the textile material is passed through a mixed padding bath containing permethrin and polyvinyl acetate to apply and fix the components by a single bath treatment.

IPC: H04B10/67
Filed: 1985-03-15
Abstract: PURPOSE:To always operate an APD at the operating point of a high current multiplication factor and also stably by monitoring the noise level of an out- band in the output terminal of a pre-amplifier connected to the output of the APD and controlling the bias voltage of the APD, when said level exceeds some reference value. CONSTITUTION:The APD 1 receives an optical signal and converts it to an electric signal and the converted electric signal is amplified by the pre-amplifier 2 and also amplified by an amplifier 3 and outputted. To the output of the pre-amplifier 2, a band pass filter 4 is connected, and the frequency component of the outside of a working band is extracted from in the electric signal. The extracted frequency component of the outside of the working band is converted to a DC voltage by a detector 5. This DC voltage V is inputted to a comparator 6 and compared with a prescribed voltage value V0. If the DC voltage is larger than the prescribed voltage value V0, a bias voltage is lowered by executing feedback. On the other hand, if the DC voltage is smaller than the prescribed voltage value V0, the bias voltage is not changed.

Title: Removal of soot in exhaust gas economizer or the like
Inventor: ONISHI TOSHIHARU
IPC: F28G13/00
Filed: 1987-03-09
Abstract: PURPOSE:To remove soot, adhered to a heat transfer tube, easily and perfectly, by a method wherein a coating layer is formed on the surface of the heat transfer tube by spread soluble coating agent and the soot is removed from the heat transfer tube together with the coating agent by spraying water on the coating layer when the soot is adhered to the heat transfer tube. CONSTITUTION:A coating layer is formed on the surface of a heat transfer tube 2 by injecting coating agent from a coating agent injector 4. The coating agent is soluble by water or solution at a normal temperature while the solution is injected directly from the coating agent injector 4. When the coating agent is made of synthetic resin, the resin is injected agent is inorganic salt, it is changed into solution and, then, is spread by injection to form the coating layer. After forming the coating layer on the heat transfer tube 2, a main diesel engine is operated to feed water into the heat transfer tube 2 and retrieve the heat of exhaust gas G. The soot in the exhaust gas is adhered to and accumulated on the heat transfer tube 2, however, water is sprayed against the heat transfer tube 2 by a spraying device 6 to solve the coating layer. The soot, adhered to the heat transfer tube, may be separated and removed from the heat transfer tube 2 together with the dissolved coating agent by the dissolving of the coating layer.

Title: Die for manufacturing molding and manufacture thereof
Inventor: AOYANAGI SHIGERU
IPC: B28B7/16
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent moldings from being arranged in a disorderly manner when being attached plurally in row by installing a registering mark die part at a boundary between the molding die part of a mold face and the outside of the molding die part or at a position away from the bounding by a specified dimension. SOLUTION: The die for manufacturing moldings comprises a molding die part 11 with an arranged latticelike pattern on a molding face and a registering mark die part 2 with a square cross section projecting at a position distant by L outside the molding die part 11. Since moldings manufactured as described have edges at an accurate position, it is possible to attach the moldings at an accurate position, it is possible to attach the moldings at an accurate position without the help of the registering mark die part merely by attaching the moldings using the edges as references, when attaching the moldings in an orderly manner on an outer wall or the like. Besides, as the formed mark, of the uncompleted molding, which is provided during manufacturing the molding, is cut, the mark no longer remains.  Consequently, the moldings such as outer wall materials or the like are without the formed mark and therefore, the moldings are clean and good-looking.

Filed: 1990-03-02
Abstract: PURPOSE:To measure a magnetic field by simple and inexpensive constitution with high sensitivity and high accuracy by constituting a magnetic element by winding an exciting coil and a detection coil around a linear or beltlike magnetic core which has bistable magnetic characteristics. CONSTITUTION:The magnetic core 1 made of a (Co50-Fe50)78-Si9-B13 amorphous alloy wire which has the bistable magnetic characteristics is excited with an AC current which is led from a power circuit 4 for excitation to the exciting coil 2. At this time, the amplitude H0 of the exciting AC magnetic field is set to a value exceeding a reverse axis formation limit magnetic field H*. Therefore, the magnetism state of the magnetic core 1 corresponds to an AC magnetic field H0sinomegat and varies periodically on a hysteresis curve and a steep voltage pulse is generated by the detection coil 3 at the time of magnetism inversion from (c) to (e) or from (d) to (b) shown in a figure. Then when an external magnetic field Hex operates on the magnetic core 1 and a state of Hex>H0-H* is entered, the magnetic core 1 is not inverted in magnetism, so that no voltage pulse is generated. This state is detected 5 as an external magnetic field detection signal indicating that there is an external magnetic field exceeding H0-H*.

Abstract: PURPOSE:To prevent the decrease in the optical coupling efficiency by progressively decreasing the diameter of the joined parts where optical elements are fixed to each other by fillet welding as the joined parts become more distant from the fillet welded part to form a tapered surface. CONSTITUTION:The optical elements SMF to be fixed to each other by laser fillet welding are joined by the tapered surfaces 15a and 16a with the diameter decreasing as the joined parts become more distant from the fillet welded part (b).
