Title: Induction heating device
Inventor: NOMURA TOSHIHIRO
IPC: H05B6/10
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To provide an induction heating device whose end surface can be efficiently heated particularly by welding of metallic bars or the like by arranging plural coils to generate magnetomotive forces in the direction perpendicular to the central axis of the metallic bars, and connecting them so that the magnetomotive forces of the respective coils can be added to each other. SOLUTION: Two coils 21 and 22 are arranged so as to cover a part to which metallic bars 1A and 1B are joined. A reason for being constituted in this way is that a butting end surface of the metallic bars 1A and 1B can also be heated, but they are connected so that respective electromotive forces of the coils 21 and 22 can be added in the direction perdpendicular to the central axis of the metallic bars 1A and 1B. The two coils 21 and 22 are connected in series to each other. In this way, since the coils are divided into two parts, the metallic bars 1A and 1B can be easily mounted on and demounted from the coils 21 and 22. The coils 21 and 22 are desirably excited by a high frequency power source 5 of two phases or four phases.

Title: Method for modifying resin
Inventor: KASAI HIROAKI
IPC: C08J7/00
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To improve the water repellency or hydrophilicity of the surface of a resin without applying a different type of a material such as a bonding layer to the surface by irradiating its surface with ion beams. SOLUTION: When the surface of a resin is irradiated with ion beams, the surface is etched by the energy of the colliding ions to form fine acicular irregularities thereon. This irradiation improves the water repellency of a material having water repellency (an angle of contact with water of at least 90 deg.) when it is smooth and improves the hydrophilicity of a material showing hydrophilicity (an angle of contact with water of below 90 deg.) when it is smooth. It is possible to simply impart high water repellency to the surface of a resin by irradiating the surface with ion beams and forming thereon a layer having an angle of contact with water of at least 90 deg. when it is smooth (for example, coating with a solvent-soluble fluororesin). It is desirable that the energy of ions used in irradiation is in the range of 5-40 keV.

Filed: 1984-06-29
Abstract: PURPOSE:To enable a ship to take various sailing attitudes, by disposing, between a stationary member and a support member for securing an outboard engine, a lift cylinder device coupled at its one end to the stationary member and at its the other end to a link by means of pins. CONSTITUTION:An attachment unit 10 allows an outboard enging 12 to be elevated due to the extending and retracting motion of a lift cylinder device 17 which is driven by a pump, relative to a ship 11. If four members, a stationary member 13, a support member 14, a first link 15A and a tilt cylinder device 16, form a parallel rectangular linkage due to the retraction of the cylinder device 16, the outboard engine 12 is only moved in the vertical direction so that it is possible to aim at effectively using the space in the ship. Meanwhile, if they form a not parallel rectangular linkage due to extension of the cylinder device 16, the outboard engine 12 is moved up and down while being tilted so that a part of a propeller 32 is positioned above the water surface to decrease the propelling resistance to establish a high speed sailing condition or a shallow sailing condition.

Title: Electromagnetic fuel injection valve for internal combustion engine
Inventor: KONNO HITOSHI
IPC: F02M51/06
Filed: 1995-05-31
Abstract: PURPOSE: To reduce opening delay and closing delay by arranging a plurality of coils which compose a magnetic circuit, thereby carrying current to a plurality of coils at the opening operation for enlarging magnetic attraction force, and reducing attraction force in an opened state. CONSTITUTION: Two coils 30, 31 are wound, while each one side is connected to form a tap part 33 and connected to a power source 32, and the other side ends are arranged through driving circuits 36, 37. The driving circuits 36, 37 are switched ON or OFF based on a signal from a CPU 38, for controlling current carrying to the coils 30, 31. Current is carried to both the coils 30 and 31 for a specified time from starting the current carrying. Strong magnetic flux is generated and speedy opening operation is performed, for reducing opening delay. After a specified time passed, current carrying to one coil 30 is stopped, keeping the current carrying only to the other coil 31. In such a state, the current carrying to the coil 31 is also stopped. Since magnetic attraction force is small originally, speedy closing operation is enabled for reducing closing delay.

Title: Medicine for curing damage of corneal parenchyma
Inventor: OTSUKI TOMOHIRO
IPC: A61P27/02
Filed: 1995-05-31
Abstract: PURPOSE: To obtain a safe corneal prenchyma damage-curing medicine capable of reducing corneal opacity and pain caused in a process for healing the damaged corneal parenchyma, capable of healing the damage to the normal state in an early stage, and free from side effects such as those of steroid medicines. CONSTITUTION: A corneal parenchyma damage-curing medicine contains taurine in an amount of 0.1-3wt.% as an active ingredient. Since an antiseptic agent (e.g. benzalkonium chloride) usually used as an essential ingredient on the preparation of an ophthalmic solution is not used, the irritation of an eye with the antiseptic agent on the application of the corneal parenchyma-curing medicine to the eye can be prevented. The corneal parenchyma medicine is suitably compounded with other ingredients for ophthalmic solutions and subsequently prepared by a conventional method. The daily administration of the corneal parenchyma medicine is performed several times, preferably 3-6 times.  The usual ingredients for the ophthalmic solutions include methyl nestigmine sulfate, an antiinflammatory agent (e.g. glycyrrhizinic acid dipotassium salt), an antihistaminic agent (e.g. diphnhydramin hydrochloride), an afflux- removing agent (e.g. naphanoline hydrochloride), a vitamin (e.g. active type vitamin B2 ), an amino acid, a refreshing agent, a polymeric additive, a stabilizer, and a preservative.

Title: Drying method for grain
Inventor: YAMAMOTO SOICHI
IPC: F26B25/22
Filed: 1990-05-23
Abstract: PURPOSE:To dry grain at a proper temperature of hot air according to distribution of moisture content by measuring moisture content of grain a plurality of times, judging distribution condition of measured value of moisture content, and controlling temperature of hot air. CONSTITUTION:Moisture content of grain is measured a plurality of times, and distribution condition of measured value of moisture content is judged; when the distribution is partial to the side of high moisture content or distribution is normal or approximately normal with wide width of distribution, temperature of hot air is fallen, when the distribution is partial to the side of low moisture content or normal or approximately normal with narrow width of distribution, temperature of hot air is risen. Of the distortion of distribution of measured value, for instance, relative skewness one of skewness is obtained by dividing difference between average value of measured value and the mode by reference deviation of measured value. When the code of this value is positive and absolute value is high, distribution of moisture content is positive asymmetrical distribution, and distribution of moisture content spreads to a high value. Thus, grain can be dried rapidly without damages by heat such as cracking, etc.
