摘要： PURPOSE:To shorten remarkably the winding time of the wound core to a coil by a method wherein two formed wound cores are wound at the same time by a common winding belt around a pair of leg parts of a coil preliminary wound and formed. CONSTITUTION:Formed and wound two cores 3, 33 are equipped respectively to supporting spools 2, 32 rotation freely by supporting rollers 2a, 32a. Both leg parts 5a, 5b of the coil 5 are fixed as to face with the wound cores 3, 33 respectively. Then the ends of the outermost circumferential layers 11, 38 of the wound cores 3, 33 are fixed temporary at parts X, Y passing the inside of the coil leg parts 5a, 5b, and are made to hold large circular shape by guide poles 6, 36. The belt 8 is equipped in common to the outer circumference of the two circular shapes thereof, and after the wound cores 3, 33 are wound forming large circles having the same winding thickness, the guide poles 6, 36 are removed, the temporary fixing at the parts X, Y are released, and the belt 8 is driven moreover to wind the wound cores 3, 33 around the coil leg parts 5a, 5b at the same time by stability generated by elasticity of the wound cores.

摘要： PURPOSE:To provide high adhesion to dental resin materials and stable durability of adhesion by activatng the surfaces of cleaned dental alloys with liquid contg. organo functional silanes and/or partial hydrolyzates thereof. CONSTITUTION:After the surfaces of dental alloys are cleaned, the surfaces are coated with liquid contg. at least 1 kind organo functional silanes having the general formula or their partial hydrolyzates (in the formula, R; an alkyl group having 1-4C, R'; bifunctional hydrocarbon having 1-12C or group-CH2CH2CH2 NHCH2CH2-, X; -NH2, -SH, -OH or -Cl groups, (a); 2-3, (b); 0-1 and a+b=3). The above-mentioned cleaning is accomplished preferably by mechanical or chemical means. The above-mentioned organo functional silanes are used as they are or used in the form of an aq. soln. by hydrolyzing part or the whole of alkoxy groups.

摘要： PURPOSE:To enable direct control of oscillating state in the laser by varying a voltage applied to the laser element. CONSTITUTION:Only the center of the semiconductor layers 2-5 grown epitaxially are retained in stripe state, and are mesa etched, and thereafter p type Ga1-zAlzAs buried layer 6 is epitaxially grown on a crystalline substrate 1 at the part removed by etching. An n type GaAs buried layer 7 is epitaxially grown on the layer 6, and is aligned with a cap layer 5. Thereafter, source electrode S, is formed under the substrate 1, and a drain electrode D is formed on the layer 5. A gate electrode G is formed on an n type GaAs buried layer 7 in predetermined interval with both ends of the drain electrode D. With the above steps, the semiconductor laser can be constructed. When the gate applied voltage is increased higher than the drain voltage, the laser light can be stopped in oscillation.

摘要： PURPOSE:To smoothly wind a core, by rewinding a shaped wound core so that its innermost layer is located most outside and by winding the rewound core around a leg of a coil. CONSTITUTION:A turning force oriented in the direction of an arrow is applied to a shaped wound core 30 made of a silicon steel band. The wound core is rewound so that its innermost layer is located most outside. This results in providing a rewound core 3 in which the innermost and the outermost layers are replaced with each other. The rewound core 3 is placed on an inner drive roller 4. The end of the outermost layer of the core 3 is passed inside a leg 7 of a coil 5. Since the core 3 has a self- contracting property, it winds itself around the leg of the coil 5. Further turning forces are applied to the inner drive roller 4 and another drive roller 2 to transfer the core 3 toward the leg 7 of the coil 5. The core 3 is thus wound across the coil 5.
