Title: Composite textured yarn having unevenness of thickness and production thereof
Inventor: KOJIMA YASUHIRO
IPC: D02G3/36
Filed: 1993-08-20
Abstract: PURPOSE:To obtain a processed yarn, having unevenness of thickness in the longitudinal direction of the yarn and a specific relationship of the ratio of filling degree of the yarn between thick parts and thin parts of the unevenness of the thickness and thereby a spun yarnlike natural uneven feeling and excellent in high-order processability. CONSTITUTION:This composite textured yarn satisfies the following formula: 1< filling degree of thin parts/filling degree of thick parts) <=2 [with the proviso that the filling degree denotes the ratio = (weight of the yarn/volume of the yarn)]. The textured yarn is obtained by feeding drawn polyester yarn as core yarn at a constant speed, feeding highly oriented and undrawn polyester yarn while changing the feed speed, applying interlacement by the air turbulent texturing and then heat-treating the resultant interlaced yarn.

Title: Formation of ii-vi compound semiconductor thin film
Inventor: KOMATSU HIROSHI
IPC: H01S5/00
Filed: 1987-08-20
Abstract: PURPOSE:To make it possible to achieve self-alignment and excellent reproducibility and to improve productivity, by epitaxially growing a II-VI compound semiconductor thin film on a semiconductor substrate, on a part of which a mask is formed. CONSTITUTION:SiO2 is embedded in the surface of a double-hetero(DH) substrate. A stripe shaped SiO2 mask 106 is formed by a photoetching method. Thereafter, with the SiO2 as a mask, the substrate is etched to the intermediate part of a P-type clad layer. Thus, a rib 107 is formed. Then ZnSe thin film layer 108 is epitaxially grown approximately flatly on the DH substrate so as to embed the rib. At this time, the attachment of the ZnSe thin film is not recognized on the SiO2 mask 106. The ZnSe thin film is selectively formed on the substrate other than the SiO2 mask part. Since the SiO2 mask, which is used for etching the DH substrate, is intacly utilized, self-alignment is performed, and the reproducibility becomes excellent.

Title: Manufacture of semiconductor thin film
Inventor: OKUMURA NOBU
IPC: H01L21/77
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To create at a high throughput on a large substrate a highly uniform semiconductor thin film having a high electron-mobility, by projecting the double pulses of a laser beam on the non-single-crystal semiconductor thin film, and by setting energy density in each pulse within the threshold of its fine- crystallization energy density caused by the projection of a pulse laser beam. SOLUTION: After depositing as a cover film a silicon oxide film 2 on a glass substrate 1 by a plasma chemical vapor deposition method, an a-Si film 3 is deposited thereon. Then, a XeCl laser beam 50 having predetermined dimensions is projected on the a-Si film 3 to set the threshold of its fine- crystallization energy-density to, e.g. 470 mJ/cm2. In this case, by synchronizing two light sources 4, 5 with each other through a controller 6, the double pulses of a laser beam are projected through an optical system 7 on the a-Si film 3 of the glass substrate 1 provided in a chamber 8. As the projective conditions of the double pulses of the laser beam, the energy densities of first and second laser beams are set respectively, e.g. to 400 mJ/cm2 and 240 mJ/cm2 to make them not larger than the threshold of the fine-crystallization energy-density of the a-Si thin film 3.

Preferably the electrolyzed aqueous solution is adjusted to pH 5.0-6.5 and 3-30 ppm available chlorine concentration. Especially in the case of the maintenance of the freshness of vegetable and fruit, preferably the electrolyzed aqueous solution is adjusted to pH 6±0.5 and 10-20 ppm available chlorine concentration.

Title: Optical information recording and reproducing device, optical head and optical recording medium
Inventor: NAKAO TAKESHI
IPC: G11B7/135
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To enable high density recording by using a magnetic field modulated recording method, recording/reproducing information through converged irradiation of a nearly circular polarized beam to a magneto-optical disk, and thereby contriving a high S/N of a magneto-optical signal reproduction. SOLUTION: Reflected light (nearly circular polarized light) from a disk 1 becomes a linear polarized light again, after passing through an objective lens 8 and an 1/4 wavelength plate 6. Since it passes through the 1/4 wavelength plate twice, however, the polarizing direction of the linear polarized light in a two-way path crosses at right angles to the polarizing direction on a going path. Consequently, after the total reflection by a polarizing beam splitter 5, it is divided by a beam splitter 12 into the optical flux which is guided to an optical system 13 for detecting a light spot control signal and the optical flux which is converged on a photodetector 15 with a lens 14 and which detects/ reproduces information signals to be recorded on the disk 1.  The information recorded are detectable by the intensity change of the reflected light of the disk 1; therefore, the structure is simpler than an optical system by a differential detecting method.

Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To control various kinds of information in one piece with a measuring instrument by reading control information from a connected external signal-processing device. SOLUTION: A measuring instrument 1 is provided with a storage means 1a for arbitrarily rewriting and adding information with a non-volatile storage element and generates a periodical output signal according to the amount of rotation of a shaft 1b. The measuring instrument 1 is connected to a measuring primary standard 3 with connection equipment 2, an information- processing means 4 stores information from the measuring primary standard 3 into the storage means 1a, and reads information from it. The information-processing means 4 and the measuring instrument 1 can be connected by connection wires 5 and 8 and can be separated by disengagement.  A cumulative error over one period of the measuring instrument 1 and the measuring primary standard 3 becomes a periodical signal, and a control device 4b writes the cumulative error into the storage means 1a as angle information and error information via the connection wire 8. As a result, an error can be corrected by subtracting the error information from the measurement value. After that, the information-processing means 4 and the measuring instrument 1 are separated and can be combined with a signal-processing device for measuring an arbitrary amount of rotation for use.
