Abstract: Provided is thin lightweight woven fabric which is suitable for use as covering fabric for down wear, down jackets, futons, sleeping bags, etc. and which, even when subjected to bias deformation, can retain low air permeability. The present invention relates to thin lightweight woven fabric constituted of synthetic fiber multifilaments, characterized in that in a cross section of the warp or weft constituting the woven fabric, the degree of overlapping between adjacent groups of monofilaments is 0.6 or greater for either the warp or the weft and that the woven fabric has a basis weight of 15-50 g/m2. The invention further relates to sports clothing, ticking, and inner-bag woven fabric which are each obtained using the thin lightweight woven fabric.

Abstract: If an event set in advance is detected by state storage event detection unit 119 when an instruction is executed, then this is reported from state storage event occurrence reporting unit 120 to state storage unit 116, by which state storage file 118 is produced. Simultaneously, a state storage file name and a situation upon the storage are stored in a correlated condition into storage situation management file 122 by storage situation management unit 121. When a certain debugged state is to be restored, by referring to the information, the state storage file can be determined readily from among existing state storage files.

Abstract: A data processor provided with a debug device which performs a simulation and debug on a user program for use in program development for a microcomputer which uses a stack area in order to save a program counter's value and a stack area control device which controls the stack areas in which the stack area control device comprises a using stack area control unit controlling the stack area used by an instruction including functions and interruption routines constituting the user program by use of the access mode information indicating write permit or write inhibit and a stack area access check unit detecting an abnormal access operation into the stack area on the basis of the access mode information.

Abstract: A reflection type imaging optical system is provided with at least one reflecting mirror, whose reflecting surface is constructed of a plurality of zone areas different from each other in spectral reflectance characteristics. Further, in the optical system, the spectral reflectance characteristics of each zone area are selected so that an incident angle providing the maximum reflectance when a ray of light of a predetermined wavelength is incident on each zone area has a value between the maximum and the minimum of the incident angle in the zone area. The reflection type imaging optical system thus provides an important advantage in practical use in that the reflection efficiency of each reflecting surface is enhanced to bring about the brightness necessary for the imaging surface.

Abstract: An X-ray microscope is provided with an X-ray source, a converging optical system collecting radiation emitted from the X-ray source, a stage on which an object is placed, and a detector having sensitivity with respect to radiation of wavelengths ranging from an X-ray region to a vacuum ultraviolet ray region, in which a filter eliminating long wavelength components from the radiation emitted from the X-ray source is disposed in an optical path from the X-ray source to the detector. Whereby, the X-ray microscope has important advantages in practical use that radiation of a desired wavelength region can be sensitively detected from the X-ray source, without bringing about large size and high cost of the optical instrument even where the X-ray source is used as a radiation source for white light.
