Title: Cutting method by wire sawing
Inventor: OKADA KUNIO
IPC: B28D1/08
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To carry out cutting work by a method for horizontally cutting a concrete structure under water by wire sawing, more easily and quickly than the conventional cutting methods which are carried out by driving a wedged spacer into a cut interval in order to maintain the cut interval, when cutting has proceeded to a certain extent. SOLUTION: Drilling at a cut interval 23 of a concrete structure 21 is carried out by driving a core drill 22 for rotation, the drill of which is constituted of a cylindrical main body detachably fixed to a shaft to be driven for rotation by a motor reducer, and diamond chips fixed to the front end of the main body. Then, the core drill 22 attached to the concrete structure 21 is left as is, and the weight of the concrete structure 21 is borne by the core drill 22. The attachment of the core drill 22 to the concrete structure 21 is facilitated by the drilling work, and when attached, it can make contact with the concrete structure with a wide contact area, whereby the number of the core drills 22 for use can be reduced, to thereby reduce workload.

Abstract: PURPOSE:To provide a wiper blade, which allows long time maintaining of excellent slipping and wiping performances. CONSTITUTION:A wiper blade is molded with a base rubber which is a rubber having unsaturated bond in the molecular structure. The surface of this molding is subjected to the halogenating process. A film of polyvinylidene fluoride, polyvinyl chloride, or polyurethane is formed over the surface of this wiper blade. Polymeride of polyvinylidene fluoride, etc., is dissolved in a solvent and applied to the wiper blade, and then the solvent is removed through volatilation. Thereby a thin polymeride film of polyvinylidene fluoride, etc., is formed in tight attachment to the wiper blade. This film is of 1-100mum thick and gives anti-weatherability, anti-abrasiveness, and water resistance to the wiper blade. Also inclusion of a solid lubricant in the film can give the wiper blade a further favorable slipping performance.

Title: Magnetic track for running magnetic levitator and running method thereof
Inventor: SUZUKI HARUHIKO
IPC: E01B25/30
Filed: 1994-12-27
Abstract: PURPOSE: To realize continuous branching through the use of pin stop effect without bringing a magnetic levitator into stationary state by forming the point of branch track of a plurality of rhombic electromagnets and connecting them to exhibit different polarities. CONSTITUTION: Electromagnets having rhombic pole faces 3, 4 are disposed at two points at a branch point of a track. Two electromagnets are excited to exhibit the opposite polarities and the current supply is previously regulated to arrange the flux in the turning direction. Consequently, the course can be changed by simply reversing the direction of current supply to the electromagnet. In other words, when the electromagnet is excited such that the pole A serves as S pole and the pole B serves as N pole, a traveling body (magnetic levitator) advances in the direction 1 and when the electromagnet is excited such that the pole A serves as N pole and the pole B serves as S pole, the traveling body advances in the direction 2.  With such arrangement, the magnet track can be branched continuously through effective use of pin stop effect without bringing the traveling body into stationary state.

Title: Formation of coating film
Inventor: KAWAHARA NORISHIGE
IPC: C25D5/18
Filed: 1989-12-18
Abstract: PURPOSE:To form a coating film having fixed properties by wet electrolysis on the same atomic level as in dry one by periodically imparting an external force while controlling the potential between the soln. contg. a material to be deposited and a conductor to be deposited with. CONSTITUTION:A coating film having fixed properties is formed by wet electrolysis on an atomic level by keeping the electrical double layer between a depositing electrode C and an electrolyte at a fixed state, or the potential difference between the depositing electrode and electrolyte and the current density are controlled based on the information on a response current waveform due to the periodical external driving force. Accordingly, the concn. of the material to be deposited in the diffuse layer or electrical double layer and the soln. structure are not changed because the potential difference and current density are changed. Meanwhile, an external driving force is periodically imparted to restore the electrical double layer tending to change by the change in the concn. of the material to be deposited, hence the double layer is kept at a fixed state, and a homogenous coating film of the deposit is practically obtained on the atomic level.

IPC: H03H9/19
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To facilitate frequency adjustment and to prevent frequency change after adjustment by forming an input-output electrode on one principal plane of a piezoelectric piece and common electrodes on the other principal plane, connecting the common electrodes in a common manner and making an inter- input electrode an input side and an inter-output electrode an output side. SOLUTION: Common electrodes 4 of two crystal filters 1a and 1b where the common electrodes 4 are formed on one principal plane and input-output electrodes 2a and 3a are formed on the other principal plane are connected to each other by external connection to be made earth ground. Further, inter- input electrodes 2 are defined as an input end and inter-output electrodes 3a are defined as an output end. Then, the input-output terminal becomes one that is independent of the earth terminal to be able to be a balanced filter. Because the crystal filters 1a and 1b have the common electrodes 4, frequency adjustment is performed by adding a metal film on the common electrodes 4. Then, it is possible to make adjustment work easy and also to prevent a frequency from changing after adjustment because the electrodes 4 do not have to be divided.
