Abstract: PURPOSE:To permit molding of a molded form made of fiber reinforced resin which is high in accuracy and especially in roundness by a method wherein the titled mold is constituted of split molds, for molding a cylindrical form having recesses and projections on a part or the circumference of the molded form, and a taper ring, supporting said split molds from the inside of the molds. CONSTITUTION:A mold for molding is constituted of a split mold 1, a taper ring 2, a ring 3 for fixing the split mold and bolts 4. A taper pin or the like for aligning the axial positions of the split molds can be mounted on the mold. Carbon steel or non-iron metals such as chrome molybdenum, aluminum or the like can be used as the material of the mold, however, it is preferable to utilize a low-expansion alloy, such as invar or the like, which has a small thermal expansion coefficient. The taper of the taper ring is preferable to be the degree of 1/20-1/200. The molds are turned about the axial center and they come into the same configuration when they are turned at least 180 deg.. Filament winding method is conventional as the shaping method of the fibers of fiber reinforced resin.

Title: Pointing device
Inventor: KUSAKA YUKI
IPC: G06F3/038
Filed: 1989-02-20
Abstract: PURPOSE:To attain stable operation by an easy operating method with a space where only a pointing device can be placed by determining the direction and speed of a cursor according to the direction and distance between the center point of a hemispherical fixed part and the center point of a hemispherical moving part which moves in contact with the surface of the fixed part. CONSTITUTION:The center point 3 of the fixed part and the center point of the moving part 2 are the center points of respective constitution parts. The fixed part 1 is hemispherical and the moving part 2 is positioned on the fixed part 1 and moves in an optional direction in contact with the upper surface of the fixed part 1. Further, when the cursor on a screen is moved by a constant distance in one fixed direction, the center point 4 of the moving part is moved from the center point 3 of the fixed part in the desired direction. At this time, the moving distance of the moving part 2 corresponds to the speed of the cursor, so the speed is limited by adjusting the moving distance and the center point 4 of the moving part is returned to the position of the center point 3 of the fixed part at the end of the movement. Consequently, the stable operation is attained by the easy operating method with the space wherein only the pointing device can be placed.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a scanning exposure method in which scanning in an inward direction from the outer side is also carried out on the periphery of a substrate and which has no hindrance to focusing, and a method for manufacturing a semiconductor device using the exposure method. SOLUTION: In this scanning exposure method, the pattern of a reticle R is transferred onto a substrate W through a projection optical system PL. Focusing of the projection optical system PL is carried out by detecting the position of the system PL in the direction of the optical axis on the substrate surface in a first region on the substrate W. Outward scanning exposure of the substrate W is carried out with respect to the first region, and the position in the direction of the optical axis on the substrate surface is saved.  In scanning exposure in a second region adjacent to the first region, from the state where the projection optical system PL is focused at the saved position in the direction of the optical axis, position detection of the projection optical system PL in the direction of the optical axis on the substrate surface in the second region, and focusing of the projection optical system, are started, and inward scanning exposure of the substrate W is carried out with respect to the second region. Since the next shot is started to scan the substrate inwardly in accordance with the information of the outward scanning shot of the substrate, the focusing time is short.

Abstract: PROBLEM TO BE SOLVED: To manufacture a semiconductor laser with a small threshold by forming an active layer between insulating films. SOLUTION: An insulating film is deposited on a p-InP substrate 101. The insulating film is so patterned that a stripe of an opening part turns in a <011> direction of the substrate 101.

Filed: 1985-03-04
Abstract: PURPOSE:To equalize effective areas on soldering among electrode patterns having different length, and to eliminate the need for the variation of the positions of soldering by forming projecting sections consisting of an insulator to long-sized electrode patterns. CONSTITUTION:A projecting section 3 composed of an insulator partitioning the surface of a long-sized electrode pattern (No.1 terminal) 1 shaped to a chip carrier package 4 is formed at a position in the same length as other electrode patterns 2 on the electrode pattern 1, effective sections on soldering on two kinds of the electrode patterns 1, 2 in different length are equalized, and the projecting section 3 can be shaped easily through screen printing, etc. Since solder adhering on the electrode pattern 1 for No.1 terminal is dammed by the projecting section 3, the effective section on soldering is contracted and limited within a range corresponding to the same length as other electrode patterns 2. Accordingly, the effective section on soldering on the electrode patterns 1, 2 having different length are kept within the same length range, and effective areas thereof are made the same, thus no displacement in the longitudinal direction of the central section of a solder sagging takes place even through pre- soldering, then eliminating the need for the variation of the position of soldering of a substrate.

Filed: 1986-02-26
Abstract: PURPOSE:To increase the degree of freedom for the layout of a gear train by furnishing two sets of speed change gears on one side of a synchromesh device, and applying it to the case where either left or right of the synchromesh device has no margin. CONSTITUTION:The power from a sub-transmission 5 is fed to the input shaft 31 of a main transmission 6, and each speed-changed power is fed to the output shaft 44 to be further transmitted to either of the front and rear wheels after a differential device 7.

In case the transfer device 9 is in engagement, on the other hand, the power on the output shaft 44 is transmitted to provide four-wheel driving. Therefore, the speed change gears are arranged on a single side of a synchromesh device, that enables application even where either has no margin, to lead to enhancement of the degree of freedom for the layout of a gear train.
