Title: Mounting structure of chip part
Inventor: KOIZUMI MAMORU
IPC: H05K1/11
Filed: 1987-07-28
Abstract: PURPOSE:To prevent the rise and floating of a chip part on reflow soldering completely by leading out an electrode for confirming soldering from the end face side in the longitudinal direction of the chip part. CONSTITUTION:Electrodes 11, 12 for confirming soldering are led out of the end face sides in the longitudinal direction of a chip part 4. The quantity of cream solder 7 protruding to the end face sides of a main body 1 and adhering on terminal electrodes 2, 3 on end faces on the electrodes 11, 12 in cream solder 7 adhering on lands 5, 6 is reduced. Consequently, moment by the surface tension of solder 7 erecting, floating or displacing the part 4 on the melting of solder 7 hardly works to both end faces of the part 4. Accordingly, the erection and floating of the part 4 on reflow soldering are prevented completely.

Title: Photomask and mask pattern forming method
Inventor: NAKATSUI HISASHI
IPC: G03F1/68
Filed: 1992-06-26
Abstract: PURPOSE:To enable the formation of semiconductor IC patterns having a sufficient resolving power in spite of exposing with g rays or i rays by diagonally forming the edge parts of mask patterns. CONSTITUTION:A chalcogen compd. 2 and a metallic thin film 3 are laminated on a substrate 1 and are exposed by using a modulated laser beam. The doping quantity to the chalcogen layer of metal is controlled by a difference in the duration of the irradiation time. Namely, the doping quantity increases when the exposing time is prolonged. Doped parts 4 are hardly etched and have a sufficient shielding property. On the other hand, the chalcogen compd. 2 which is small in exposure and is not so much doped is easily removable by alkaline etching. Then, the mask patterns by the doped parts 4 having an inclination are formed by etching away the chalcogen compd. Diffractions are decreased when the photomask obtd. in such a manner is combined with a semiconductor exposure device.

Abstract: PURPOSE:To prevent stray light from being projected and to realize the manufacture which is low in cost and high in productivity by coating the signal projection end surface of a clad part with a stray light shield material and then forming a core part, and sealing it thinnly. CONSTITUTION:The projection end surface 3 of a light-transmissive base material 2 which has a groove 1 is coated with the stray light shield material 5 by an ink roller head 4. Then a light-transmissive material which is photosetting resin and has a higher refractive index than the base material 2 is charged in the groove 1 by utilizing capillarity and set by ultraviolet-ray irradiation to form the core part 6.

When a light signal is made incident, the light signal entering the clad part can not be projected from the clad part because of the stray light shield material applied on the projection end surface of the clad part and the core sealing layer is thin, so little stray light is projected.

Abstract: PURPOSE:To enable cutting grooves quickly on a cylindrical element and eliminate a drop in configuration precision by finding the shrinkage factor of the element after cutting multi-grooves and forming the multi grooves by the use of a grinding stone for cutting the multi-grooves with predetermined groove intervals enlarged depending upon said shrinkage factor. CONSTITUTION:Shrinkage appearing when many V-grooves are processed and formed on a cylindrical element 1 for forming a multi-groove belt, depends upon the types and the arrangement directions of fiber embedded in the boundary wall of the element 1, an elastomer material forming the element and the like. So far as the same material is used, a shrinkage factor falls within an approximately constant range. Also, the fiber, the elastomer material and the like once set, rarely undergo a change and the shrinkage factor of the element 1 is approximately constant in a practical sense. Also, the shrinkage of the element 1 occurs uniformly over the entire length thereof. In this respect, the sectional form of grooves to be formed and the intervals thereof are enlarged and set on the element 1 with due consideration of said shrinkage factor, and the grooves are cut according to the intervals so set. Consequently, predetermined intervals and groove shape are obtained after the cutting work.
