Title: Detecting method for mark
Inventor: SATOU HITOSHI
IPC: H01L21/027
Filed: 1980-12-24
Abstract: PURPOSE:To remarkably shorten the exposure time in a mark detecting method by calculating a mark signal detecting step and a mark signal detecting data and approximately performing it in parallel with the step of measuring the position of a mark. CONSTITUTION:A mark M is canned by a charging beam with a beam having a scanning width L designated in advance, a distance a from the left scan starting point to the mark and a distance b from a right scan starting point to the mark are detected, an operation of measuring the value of{a+[L-(a+b)]/2}from these numerical values is performed several times, and their average value is calculated. In this case, the average value of the values measured by scanning the marks up to m times m(m<n) while scanning the mark at n times is calculated, and the position of the center of the mark is detected. Since it does not almost apparently take a time to measure the position of the mark in this manner, the exposure time can be resultantly remarkably shortened.

IPC: H01S5/40
Filed: 1986-08-04
Abstract: PURPOSE:To be able to perform a sole oscillation in a 0 deg. phase mode by so reducing the maximum refractive index of a strip at the center of an arraylike stripe laser as to be smaller toward the end symmetrically with respect to lateral directions in such a manner that an optical density distribution in an element coincides with 0 deg. phase mode. CONSTITUTION:A semiconductor laser array is periodically varied in the thickness of a P-type AlxGa1-xAs clad layer 3 by grooves 51-57, its filaments are specified in the shape corresponding to the grooves 51-57, and further gradually reduced in the thickness of an N-type AlxGa1-xAs clad layer 5 from the center toward both ends. Electrodes 7 exist in laterally symmetrical shape in a stripelike state at a part that is coincident with the centers of the grooves 51-57. Thus, an implanted carrier exists by weighting the filament (directly above 54) at the center, and decreases toward both ends. Thus, the element can oscillate solely in 0 deg. phase mode to obtain a fine emitting light only in a direction perpendicular to a resonator face.

Title: Mechanical seal mechanism
Inventor: KASHIWAMURA KAZUO
IPC: F16J15/34
Filed: 1986-08-05
Abstract: PURPOSE:To improve the durability of a sheet ring and obtain a mechanical seal mechanism having a superior durability and a high reliability, by cooling the sheet ring with a heat medium to be circulated and radiated by a heat medium circulating/radiating means. CONSTITUTION:During the operation, temperature of a sealing end surface 4 of a mechanical seal becomes high due to the generation of heat with slide. The heat is transmitted to a heat medium 25 enclosed in a cooling jacket 21 provided in a sheet ring 2b. As a result, the heat medium 25 is evaporated to generate gas 26 which in turn transfer the heat through a heat medium passage 22 formed above the cooling jacket 21 and a pipe 24 to a radiator 23. The radiator 23 conducts heat exchange between the gas 26 and the atmosphere to liquify the gas 26. The liquid heat medium is returned to the jacket 21 by the gravity. Thusly, the heat generated at the sealing end surface 4 may be continuously and efficiently radiated to the atmosphere to thereby maintain the temperature of the sealing end surface 4 at temperatures not greater than a heat resisting limit temperature. Accordingly, it is possible to obtain a mechanical seal mechanism having a superior durability and a high reliability.

IPC: B29L9/00
Filed: 1987-07-24
Abstract: PURPOSE:To depress effectively warpage of a laminated plate, by positioning metal foils on nearer sides to press hot plates in the method for preparing a laminated plate where a plurality of laminated plates having a metal foil on one face of each prepreg and a release film on the other face of each prepreg are placed through metal plates and molded by heating and pressing. CONSTITUTION:Laminated bodies 3 which are individually separated through metal plates 2 are placed between press hot plates 1. A laminated body 3 is constituted of a prepreg on one and the other face of which a metal foil 4 and a release film 5 are respectively placed. Metal foils 4 are all positioned so as to be placed on nearer sides of the press hot plates 1 and the laminated bodies 3 are symmetrically placed from the central part between the press hot plates toward the upper and lower press hot plates. As the metal foils 4 of the laminated bodies 3 are positioned at nearer sides to the press hot plates, in the cooling after molding under heating and pressing, the metal foils are gradually contracted with cooling of the press hot plates and the rapid contraction can be therefore avoided. Therefore, warpage where the metal foils are recessed due to molding of the laminated plate is remarkably depressed, and reject rate of the laminated plates is reduced. Yield of the product and characteristics of the printed base plate are also improved.
