Title: Manufacture of laminated ceramic capacitor
Inventor: NAKANISHI TAKAAKI
IPC: H01G4/30
Filed: 1990-02-13
Abstract: PURPOSE:To manufacture a capacitor where chipping and others do no occur by cutting and polishing a compound, where ceramic dielectric materials and inner electrodes are laminated alternately and thermobonded, into the shape of an element so as to smooth the edge of the element, and then removing the organic binder within the element by thermal decomposition. CONSTITUTION:A green sheet compound, which is integrated by laminating ceramic dielectric materials and inner electrodes alternately and thermobonding them, is cut into element-shaped chips by a dicing saw. These are mixed with alumina powder, alumina polishing material and water, and is put in a cylindrical aluminum pot, and is polished by rotating it for 15 minutes at the rotation of, for example, 30 times a minute. Hereby, the edge of the element can be smoothed. And it is washed in water and dried, and then it is treated in the air for eight hours at, for example, 600 deg.C so as to thermally decompose and remove the organic binder, and then is baked for four hours at 950 deg.C, thus baking is completed. Hereby, chipping does not occur at the time of manufacturing or at the time of mounting to a board, and there is no microcrack on the surface of the element, and electric capacitance per unit volume can be made large.

Title: Gear shaping device
Inventor: SATO NAOTOSHI
IPC: B23F9/12
Filed: 1993-01-26
Abstract: PURPOSE:To provide a gear shaping device having the capability of inexpensively and yet efficiently machining the tooth space of different size and shape. CONSTITUTION:A tool main spindle 26 is caused to rotate on the operation of a servo motor 62 for tool rotation via a reduction gear train 70 and a shaft 68. The rotation of a servo motor 82 for tool travel is converted to linear motion via a ball screw 84 and a nut 86 for transmission to the spindle 26, thereby causing the travel thereof along a rotational center line. In the case of the rough machining of tooth space on a gear element, a front milling cutter 34 is mounted on the spindle 26 and shifted, while rotating, to perform the rough machining of the tooth space. The finish machining of the space is undertaken after changing the cutter 34 to a disc broach. According to this construction, the travel distance of the front milling cutter 34 and the disc broach can be arbitrarily adjusted by controlling the rotation of the motor 82. Furthermore, a relief section can be formed, and a correction or the like can be made, regarding crowing and tooth trace.
